Mapping the perfect storms: Where poverty, livestock and disease meet in terrible triage

Posted on November 6, 2012 by Susan MacMillan

The following remarks are a transcript of the second part of a presentation made last week by Delia Grace, who works at the International Livestock Research Institute (ILRI), in Nairobi. Grace, a Irish veterinary epidemiologist, leads ILRI’s research on food safety in informal markets in developing countries and on ‘zoonoses’—diseases shared by animals and people. Grace also leads a component on agriculturally related diseases of a new multi-centre CGIAR Research Program on Agriculture for Health and Nutrition, which is headed by John McDermott, former deputy director general-research at ILRI, who is now based at ILRI’s sister CGIAR institute the International Food Policy Research Institute (IFPRI), in Washington, DC, USA. Grace is also a partner in another multi-institutional initiative, called Dynamic Drivers of Disease in Africa.

A prolific writer of scientific publications and a scientist of particularly wide research interests, Grace began her ‘big-picture’ talk on zoonoses—on why, and if, they are ‘the lethal gifts of livestock’—with an overview of human health and disease at the beginning of the 21st century. Go here to read part one: The riders of the apocalypse do not ride alone: Plagues need war, famine, destruction–and (often) livestock, ILRI News Blog, 4 Nov 2012.

Here we begin part two of this ILRI ‘livestock live talk’ presentation by Delia Grace on ‘The lethal gifts of livestock’.

Getting a handle on why zoonotic diseases matter, to whom and how much
‘So, we’ve discussed the links between livestock and disease and why livestock play such an important role in human disease. The next question we have to ask is to try and put some details on this, to put some parameters on it. So, if disease matters, and if animals have a big role in disease, what disease matters? How much? To whom? What does it cost? And what can we do about it?

‘In thinking through this, we tend to think at ILRI of different categories, which help us get more of a handle on some of the details. So we talk about the neglected zoonoses; these are the diseases like TB, brucellosis, cystercicosis—diseases that have been eradicated anywhere people have money and care, but persist—hang on—in poor countries. We talk about emerging infectious diseases—the BSEs, the SARS, the bird flus, Rift Valley fever, blue tongue—diseases that are changing their patterns and becoming more important. Then the food-borne diseases are the other big category. This is the single-most important. If you’re interested in human health and human death, food-borne diseases are the single-most important category. And finally, there are the other health risks in agro-ecosystems: How we farm and what this means for our health and nutrition.

Let the mapping begin
‘I now want to talk about some recent work we did on mapping poverty, zoonoses and emerging livestock systems in order to get a better handle on some of these questions about why it matters, who it matters to, how much it matters, and what we should or could do about it.

‘I’m going to present some work that was commissioned by DFID [the UK Department for International Development]. These were two systematic reviews that DFID asked us to do. The aim of these was to present data and expert knowledge on poverty and zoonoses hotspots in order to prioritize areas, to target areas, where prevention of zoonotic diseases can bring the greatest benefits to poor people.

‘This study took us down some interesting paths and some interesting conclusions. I’m going to talk about them in a little bit of detail.

‘So, the methods. What we wanted to do was to update global maps of poor livestock keepers. The first ever global map of poor livestock keepers was produced by ILRI around 10 or 15 years ago, again commissioned by DFID. This, I would say, was a landmark map. We also wanted to map rapidly emerging livestock systems. And here we drew a lot again on ILRI’s expertise, especially Mario Herrero’s group, which have been doing a lot of big-picture work on changes in livestock systems—what’s happening, where it’s happening and why it’s driving change. We also wanted to update one of the most iconic maps for people in the zoonoses community, and this is the map by Kate Jones on emerging infectious diseases that appeared in Nature about ten years ago (and everywhere else since).

‘We wanted to identify which were the most important zoonoses for poor people. You’d think that we’d know that, but what we find is that we have a dozen definitions and none of them agree. And then, finally, we wanted to develop the first global mapping of where zoonoses, poverty and emerging [livestock] systems come together to make hotspots, for maximum investments, for maximum bang for the buck.

Where are the poor livestock keepers?

Update in 2012 by ILRI’s Delia Grace of map by ILRI’s Phil Thornton showing density of poor livestock keepers (map credit: ILRI/Philip Thornton).

‘Here is the updated map of poor livestock keepers. I think you can see by looking at it that it’s focal. The dark areas represent high density. South Asia jumps out at us. And in Africa we see the ‘magic 7’, from the coastal regions of West Africa to Nigeria and up through the highlands of Ethiopia and right down the Rift Valley through Uganda and northern Tanzania and right down to Malawi.

‘So what can we say in our updating of poor livestock keepers?

One billion poor livestock keepers depend on 19 billion livestock. Most of the livestock in the world are owned by poor people: 24 billion in total in the world and 19 billion in poor countries. That’s a lot of opportunities for disease to spill over, 19 billion animals.

What’s more, the ‘parietal law’, the law of ‘the vital few and the trivial many’, applies. Just 4 countries have 44 per cent of poor livestock keepers. All countries are not equal.

‘Livestock matter a lot: 75% of rural people, and 25% of urban people, depend on livestock. Now ‘depend’ is one of those weasel words that we keep being asked to shine more light on. We don’t know enough—it’s amazing how little we know despite how important this is—but our best guess for now is that when we say ‘depend’ we mean that livestock contribute between 2 and 33% of household income and 6 to 36% of protein. It’s not trivial.

Where are the fast-evolving livestock production systems?

2012 maps showing changes in poultry and pig production between 2000 and 2030 (map credit ILRI/Delia Grace).

‘The second map we updated was these emerging livestock systems. As we suspected, most emergence is happening in the monogastrics, the pigs and the poultry. And of course this has been known since the landmark papers on the livestock revolution. Our maps confirm this; we’re getting a lot of change in pigs and poultry, and again it’s focal; you can see that it’s not uniform.

‘So in summary, where are we getting massive, rapidly changing systems? Big changes in numbers? Big changes in baselines? Where do we have people who don’t have a lot of experience doing this sort of farming now doing it in a big way? (Once you get naïveté along with massive intensification, you get problems.)

Poultry in several places on all continents, bovines in South and East Asia, and pigs in sub-Saharan Africa. These are the rapidly emerging livestock systems.

Where are the emerging infectious diseases?
‘Next, we updated the emerging infectious diseases map. This was a study that was originally done by Jones et al. based on all emerging diseases from 1940 to 2004. What we wanted to do was to focus just on zoonotic diseases (the 75% of all human disease that are zoonotic) and also to update it with data from 2004 to 2012.

Map by IOZ, published in an ILRI report to DFID; Mapping of Poverty and Likely Zoonoses Hotspots 2012.

‘All of these dots represent new, potentially scary, diseases. The bigger the dot, the more the outbreaks. The new diseases are the blue circles; they are the ones that happened in the last ten years. The brown are the old; those are the ones that happened in the 70 years before. Again you can see a pattern here, but it’s not the same pattern we saw in the other map.

‘What we see is that western USA and western Europe are the hotspots for disease emergence. There’s a reporting bias in here, but we believe that this is not just reporting bias but actually represents emerging events. Interestingly, the blue events, the new events, are more common in South America and Southeast Asia, as intensification takes off in these regions and start to look more like intensive [livestock] systems of the West.

Multiple disease burdens are ‘where it’s at’
‘So, what are the high-priority zoonoses? We were interested in multiple [disease] burdens. One of the things we believe leads to bad management of zoonoses is that it’s done sectorally; it falls between lots of chairs. The World Health Organisation thinks about the human burden. The United Nations Food and Agriculture Organization thinks about the animal burden. Other people think about the wildlife burden. But people too rarely get together and think about the multiple burden.

What isn’t measured isn’t managed. And we think that one great step forward is just having people think about multiple burdens. So our listing, our criteria, consists of looking at the burdens across human health, animal health and ecosystems health.

‘From lots of listings, we assessed 56 zoonoses and found that together they caused a lot of problems. But the ones that were most important tended to have a wildlife interface, had a major impact on livestock and were amenable to on-farm agricultural interventions.

Slide of ‘top zoonoses’ from ‘livestock live talk’ presentation, ‘Zoonoses: The Lethal Gifts of Livestock’, made by Delia Grace on 31 Oct 2012.

‘Just to give you some idea of the numbers, there are about 600 zoonoses and we looked at the top 50. Of that top 50, this is the human death caused by the top 13 and that by the next 43. Again, I think you can see it’s a case of the vital few and the trivial many. If you’ve got scarce resources and care about human death, you invest in the top 13, not in the bottom 43.

And here it is just broken out by individual zoonoses, and even in that top 13, you can see that there’s a difference between big killers and little killers. And sometime the ones we hear most about—and worry most about—are the ones that kill least.

‘The first thing we did then was to go to official reporting systems to try to find out where these zoonoses were and how these linked to the other things we were mapping. There are several reporting systems. There’s one by OIE [World Organisation for Animal Health], which is ‘notifiable’, that is, every OIE member has to report all their animals that die of notifiable diseases (you’d think that was easy enough). There’s also one run by FAO, and there’s Pro Med, there’s GEWS, and there’s Health Map, which is an aggregator. That a picture of Health Map, and it’s a pretty exciting innovation. A ‘bot’ trawls the web and captures all the information on diseases.

When we put all of these [official disease reporting systems] together, what we found was that they were completely useless. They told us almost nothing about the burden of diseases. They told us about exciting things, interesting things. When a kid in Buenos Aires got bitten by a rabid dog, that showed up here. But when we were interested in what is sickening and killing billions and millions of people, it was just hopeless.

‘Just to give you an example, Africa has about 250 million tropical [aggregated] livestock units; we know that around 25 million of them die prematurely every year. We estimate around half of those deaths are due to notifiable diseases. There are over 60 notifiable diseases and pretty much everything falls into these. And what’s reported? Say 10 million dead, 80,000 reported.

This isn’t just under-reporting; this is a reporting system that is not very helpful!

‘So we couldn’t use the official reports. And it’s a huge weakness. People go along blindly and mechanically collecting this data, sending it in to OIE, doing complicated analyses showing all the different effects and impacts of these diseases, but they fail to take into account that they’re only looking at the 80,000 that are reported, and not the 920,000 that are not reported. It’s sort of an exercise in futility.

‘So what we did instead was a systematic literature review. We found that the only way we could get some sort of handle on where these zoonoses are was just to keep looking through the literature, pulling it out—grey, white, published, local language—and get as many surveys as we could and geographically map them and see what they are doing. In fact, we got over a thousand studies, which was enough to get some sort of a spatial understanding.

Map by ILRI, published in an ILRI report to DFID: Mapping of Poverty and Likely Zoonoses Hotspots, 2012.

‘This is what we came up with. Where you see a dot is where 1 or more people or animals in 100 are affected by 1 or more diseases per year. At least a 1%, at least 1 in 100 are sickened or killed. The dark colour shows where the poor livestock keepers are. Again, you can see the ‘7’ in Africa, whereby the zoonoses are linked to the poor livestock keepers. You can see quite a bit in South Asia and some in Southeast Asia.

‘There is a definite link between livestock keeping and poverty, which is what we suspected, but here again there is a lot of under reporting.

An unlucky 13 zoonoses sicken 2.4 billion people and kill 2.2 million people and they affect more than 1 in 7 livestock each year. These numbers are not trivial. These are large numbers, large numbers of sickness and death.

Our zoonotic problems are big problems

Slide of ‘multiple burdens of zoonoses’ from ‘livestock live talk’ presentation, ‘Zoonoses: The Lethal Gifts of Livestock’, made by Delia Grace on 31 Oct 2012.

‘As I said, we focused on multiple burdens of zoonoses, and here are some. I won’t read through them in detail, but again, going across all of these surveys, the numbers are frighteningly high. Round about 10% of animals have brucellosis, which is a serious disease in people, causing ungulant fever, infertility in men; it can cause psychosis and depression. And it’s transmitted in milk. If you don’t boil your milk, 1 in 10 animals has brucellosis. Ten per cent of animals in Africa have tryps [African animal trypanosomiasis], reducing their productivity by 15%. With 250 million livestock units, say they’re worth USD500 each, and you reduce their productivity by 15%—we’re talking large numbers here. TB, cysticercosis, bacterial food-borne disease, all of these came up.

‘The bad news is that it’s there and it’s a big problem in animals as well as people. The good news, of course, is that this provides incentive-based ways of tackling some of these zoonoses. Because if you can manage your animal zoonoses and boost your productivity by 10 or 20%, there’s a strong incentive for you to do it. What we’ve found with these studies (and we’ve been doing a lot of them over the years), is that too often the human health attitude is that people should do this because it’s good. You should do it to protect your own health. You should do it to protect the consumer’s health. That is one of the weakest motivations of all. How many things do we not do even though we know they’re good for our health? And how many fewer things do we do if they’re not good for our health but they’re good for someone else’s health?

Give people incentives, not rules, to better manage disease
‘What we find in these informal markets, where regulation is a joke and you have a hundred vets in a country and a hundred million animals, there’s no point in regulations or officials telling people “You should do this because it’s good for you”. It has to be incentive-based. People have to see a real benefit from changing their behaviour, either in their pocket or in their social status. And it doesn’t have to be money. We found people will change their behaviour just as much if they can get a social kick out of it. If instead of being a low-status person they get to be a high-status person, they’ll change their behaviour.

‘So, in summary what did we find? There are definite [zoonotic] hotspots, which is good, because that’s what the donor wanted because that’s where the donor wants to invest. This is also a nice example of how science can generate evidence that is asked for by a donor and then influences donor behaviour, so it’s a virtuous cycle.

Where the ‘perfect storms’ lie
‘Poor livestock keepers? South Asia is the biggest. Emerging livestock systems? Again, South Asia. Zoonotic emerging infectious diseases? Western Europe and USA. Zoonoses? South Asia and central and eastern Africa.

If we are to name six countries where all of these come together, where you get the ‘perfect storm’ conditions, they are India, Bangladesh and Pakistan in Asia; Ethiopia, Nigeria and Congo in Africa.

‘So we’ve talked a bit about the big picture, human health and disease in the 21st century and why livestock matter. I’ve presented some of these findings of our mapping studies trying to get some evidence: the evidence that decision-makers want in a format they can use, in a way that motivates them to invest money.

‘But now, finally, I want to talk a bit about how we move from mapping to managing. . . .’

The riders of the apocalypse do not ride alone: Plagues need war, famine, destruction–and (often) livestock

Posted on November 4, 2012 by Susan MacMillan

a presentation made last week by Delia Grace, who works at the International Livestock Research Institute (ILRI), in Nairobi. Grace, a Irish veterinary epidemiologist, leads ILRI’s research on food safety in informal markets in developing countries and on ‘zoonoses’—diseases shared by animals and people. Grace also leads a component on agriculturally related diseases of a new multi-centre CGIAR Research Program on Agriculture for Health and Nutrition, which is headed by John McDermott, former deputy director general-research at ILRI, who is now based at ILRI’s sister CGIAR institute the International Food Policy Research Institute (IFPRI), in Washington, DC, USA. Grace is also a partner in another multi-institutional initiative, called Dynamic Drivers of Disease in Africa.

Regarding diseases, it’s not the past we have to worry about, says ILRI scientist Delia Grace; it’s the diseases we’re picking up and the lifestyle choices we’re making (picture credit: ILRI/Susan MacMillan).

‘At the moment we are 7 billion people and by 2050, we’ll probably be 9 billion.

To date, farming is not doing a very good job of feeding us or looking after our health. We have 1 billion people who are hungry, 2 billion people who suffer from ‘hidden hunger’, or micronutrient deficiencies (iron, vitamins, minerals), and we 1.5 billion people who are overweight or obese. All in some ways functions of a dysfunctional agricultural system.

‘Not only does agriculture have an important role in nutrition, it also has an important role in health. And that’s going to be the main topic of my presentation.

‘But a few facts here just to get us in the mood.

‘Of our 7 billion people, 55 million die each year; 18 million die of infection. That’s preventable—there’s no reason now why anyone should die of an infectious disease. But to put that in perspective, there are lots of other preventable things that also kill people: 1.2 million people die each year in road traffic accidents, 170,000 from fatal agricultural accidents and 22,000 (and rising) from extreme weather events.

‘Of those people who die each year . . . two-thirds live in middle-income countries and most of those people die of lifestyle-associated diseases (cardio-vascular/chronic). About a sixth of those who die each year die in high-income countries, and most of them die from being just too old—they die from things like Alzheimer’s and stroke and cardiac disease, things that often come at the end of a life. And then there are the one-sixth who die in low-income countries, and what they die of are the ‘preventables’, mainly infectious diseases.

So, where do these infectious diseases come from? When we look at diseases as a whole, we can see that most are ‘earned’. The wages of sin may be death but the wages of lifestyle choice is disease.

‘The major causes of disease on this planet are the choices we make or the choices that are forced upon us: degenerative diseases, cardiac diseases, diabetes, stroke, cancer. Allergies and asthmas, which are probably reflections of a lifestyle that was not the way we were evolved to live. Those diseases are not the focus of this discussion.

‘What we are focusing on are the “souvenirs”, the diseases we pick up from other sources. And those sources are pretty much animals. Around 60 per cent of all human diseases are shared with animals, and of the new and emerging diseases, 75 per cent are “zoonotic”, that is, they come from animals. What’s more, of the 18 million people who die of infectious diseases each year, two of the biggest killers are zoonotic, or jumped from animals to people.

‘One thing that distinguishes the “souvenir” diseases is that many of these are diseases that kill people when they are young or in the prime of their life, when they have a future ahead of them.

We’re all going to die—that’s one thing that’s fairly inevitable. If we want to spend scarce resources doing something about making our planet more healthy and productive, it makes sense to invest in the souvenirs, the diseases we’ve acquired rather than these end-of-life diseases, about which nothing much can be done.

‘In fact, some economists argue it’s cheaper to let people die once they’ve reached a certain age than it is to invest in trying to make them better, because they’re not going to contribute much more to society.

The diseases that don’t matter so much we call the ‘legacies’. These are the diseases that have always been with us, the diseases that humans brought with them in their evolution from non-human primates. It’s interesting to see that these diseases (e.g., staph, lice, typhoid) are pretty much conquered. So it’s not the past we have to worry about; it’s what we’re picking up and the choices we’re making.

ILRI scientist Richard Bishop asks Delia Grace a question following her ‘livestock live talk’ on 31 Oct 2012 in Nairobi on the subject of ‘Zoonoses: The lethal gifts of livestock’ (photo credit: ILRI/Susan MacMillan).

‘So, how do these diseases get from animals into people, these 60 per cent of diseases that we share with animals? “Spillover” is the word. Here we see what we call an epidemiological or sylvatic cycle. That’s a little pathogen living in a kind of equilibrium with its wild host. By the usual evolutionary rules, once these pathogens have been living a long time with their hosts, they tend to co-evolve so that they get a little less malignant. Otherwise, if the pathogen kills all its hosts, it’s not good for its long-term survival. So what you tend to get are complex pristine ecosystems with lots of hosts and lots of pathogens, all in an evolutionary race but all staying in a relative status quo.

‘Once you bring in humans, you can get spillover. Once humans start coming into these pristine ecosystems and start messing with them—start killing lots of animals or butchering game meat or doing other things that happen when people invade pristine ecosystems—some of these pathogens can spill over into humans. What tends to happen when they first spill over is that they’re not adapted to humans: they kill them and that’s it. That’s what we tend to see with the ebola and marburg viruses; you’ve heard about these in Uganda. They spill over, they kill, that’s it. But if they get lots and lots of opportunities to spill over to people, evolution starts kicking in, too, and they now have got a new host, a new lease, so they’re going to start being able to be transmitted more readily, from human to human.

‘The other thing that can happen in these sylvatic cycles is the spillover can occur into livestock. This can be expected. Humans have contacts with wild animals, but livestock have many more. So we often see that livestock can act as a sort of bridge to bring these wild animal diseases into people. And that’s what we see with diseases such as the Nipah virus, diseases such as avian influenza and Rift Valley fever. The host is out there somewhere in the wild; often we don’t know where it is. It’s shocking to say: we still aren’t sure where the host for Rift Valley fever is, we just don’t know. But we know it gets into livestock, and from livestock it gets into people. People can be a dead-end host—the virus can get in, sicken and kill and that’s it—or the virus can gradually start adapting to humans.

‘Some of the factors that can help this transition are increasing the densities, increasing the contacts, increasing the amount of pathogen in the environment, but also other things like habitat change, biodiversity, vector density, host density.

I would argue—this is a little bit provocative and not everyone would agree—that spillovers happen all of the time and most of the time just aren’t any big deal. A lot of the present effort to control emerging infectious diseases is perhaps not well directed because we’re dealing with problems that are intrinsically self-limiting. However, when you look back at history, in order for a spillover to become a disaster—in order for a spillover to become a pandemic, a civilization-altering disease—you need something else. I think this missing ingredient is great societal dislocation.

‘And that’s what history shows. The first big transition was the Neolithic transition. I’m going to come back to that because it’s important. Other examples, from the 13th to the 15th centuries, Europe went through a little Ice Age—we talk about climate change making it hotter today; then, it got colder. People got hungry, people, starved, people moved; you got Black Death and it killed one in three.

‘When they opened up the New World and when people came to the Americas, something like 90 per cent of the population died in the Americas, from smallpox, from measles. This is what we call ‘virgin soil’ epidemics; people who had no immunity; why? because they hadn’t hung out with livestock for long enough, according to some people, so people just died in droves.

‘But it wasn’t just a disease—it was the collapse of their society, the collapse of a highly advanced, highly stable, highly functioning society. It was destroyed from the outside and the disease came in.

The riders of the Apocalypse do not ride alone. Plague by itself needs war, needs famine, needs destruction.

‘We saw the same in the First World War, with the trenches and that massive societal misery, which led to Spanish flu and 40 million dying, and colonialization and urbanization in Africa in the early 20th century leading to HIV.

Slide from ‘livestock live talk’ by Delia Grace on 31 Oct 2012 (slide by ILRI/Delia Grace).

‘Some argue and some spend millions of dollars hearing that we are about to enter a new time of unprecedented societal dislocation. As we get massive population increases, massive climate change, massive global destruction, we’re in for another big plague.

‘Let’s look at the first epidemiological transition, just to take us back to history and to show how domestication leads to disease. The first [animal we domesticated] was the dog [15,000–30,000 BC], and some would argue that the dog domesticated us, and the last was the goose (1,500 BC), and anyone who has been chased around a farm by a goose knows that they are as yet imperfectly domesticated!

But between the dog and the goose, there’s been a long range of domestication and the animals brought disease with them, diseases we tend to think of as human diseases; measles, mumps, diptheria, flu, smallpox, they all jumped from animals, many of them from livestock.

Slide from ‘livestock live talk’ by Delia Grace on 31 Oct 2012 (slide by ILRI/Delia Grace).

‘And of course this is a dynamic: once they jumped in they can jump back; other diseases jumped from people to livestock, and once they were in the livestock, they came back again.

‘So that was the link between livestock and disease and why livestock play such an important role in human disease.

‘The next question we have to answer is to try and put some details on this, try and put some parameters on it. If disease matters, and if animals play a big role in disease, what disease matters? how much? to whom? what does it cost? what can we do about it? . . .’

Livestock in the city: New study of ‘farm animals’ raised in African cities yields surprising results

Posted on October 15, 2012 by Susan MacMillan

Leonard Gitau, a small-scale livestock farmer in Dagoretti, Nairobi, speaks to journalists during a media tour by ILRI of urban farmers in Nairobi on 21 Sep 2012 (photo credit: ILRI/Paul Karaimu).

For the first time in history, more people are living in cities than rural areas. Many of them still keep livestock. At least 800 million people in cities in developing countries practice urban agriculture, from growing vegetables to keeping camels—often in close confinement in densely populated areas.

The benefits of urban livestock keeping are many: from improved food security, nutrition and health from livestock products, creation of jobs and protection from food price volatility. But the risks in urban livestock are also large: unsanitary conditions and weak infrastructure mean that livestock can be a source of pollution and disease.

‘Zoonoses’, diseases transmitted between animals and people, are a global health problem that particularly affects the poor in developing countries. A new study by the International Livestock Research Institute (ILRI) and partners finds that zoonoses and diseases recently emerged from animals make up 26% of the infectious disease burden in low-income countries, but just 0.7% of the infectious disease burden in high-income countries.

The study, published in the journal Tropical Animal Health and Production, which was led by University of Nairobi and ILRI, is part of a series of papers that examine the facts and fiction of urban livestock keeping. The researchers note the need for evidence in the planning and practice of urban food systems and the danger of relying on perceptions or models taken from different contexts.

Here are some of the results of the study.

LOTS OF URBAN LIVESTOCK
Much more livestock is being raised in the urban areas of developing countries than most people (and policymakers) think.

THE DISEASE RISK
Domestic as well as wild animals can spread many, and some very serious, diseases to people and it is a reasonable assumption that as the population of urban areas of these and other developing countries continues to increase, the risk of zoonoses also increases.

THE GOOD NEWS
This recent in-depth study of urban zoonoses in urban environments in Nigeria and Kenya suggests that the human disease risk posed by raising, processing, marketing and/or consuming livestock in cities, city suburbs and big towns in developing countries is less than we might think.

SUPPORT INFORMAL MARKETS
Rather than bar poor people from livestock enterprises in urban areas in an attempt to protect public health, which could do the poor more harm than good, this study suggests that a more practical and equitable course is to work to enhance practices in small-scale urban livestock raising and informal livestock marketing by encouraging poor livestock producers, processors and sellers to upgrade some of their practices.

PROVIDE INCENTIVES FOR GOOD BEHAVIOUR
This study included participatory work with the local communities, and an important outcome has been the success achieved by creating incentives for the poor to improve their livestock practices rather than trying to strictly regulate these informal livestock markets, or harass the people involved, or bar them from operating altogether.

DISEASE RISKS ARE NOT WHAT WE THINK
Another important finding is that people are not the good judges of risks that they think they are; most people, including food safety officials, think that livestock foods, being so perishable, carry the greatest risk of disease in informal urban markets, but studies have shown that, for example, city vegetables are often a greater cause of disease concern than milk and meat.

TRACKING PATHOGENS AND RELATED ILRI RESEARCH
This research project was conducted jointly with the University of Nairobi, whose Professor Erastus Kang’ethe led the data collection and participatory work within Kenya, with the support of the Kenyan government and health officials. This project also expands ILRI’s long-standing research on informal dairy markets in East Africa and South Asia, led by ILRI scientist Amos Omore and others, which helped to refine dairy policies to support rather than harass sellers of ‘raw’ (unpasteurized) milk. And a new ILRI research project led by ILRI scientist Eric Fevre will investigate zoonoses further by tracking disease pathogens as they move among farms, processors and markets in Nairobi.

Delia Grace, an ILRI veterinary epidemiologist and leader of a component of the CGIAR Research Program on Agriculture for Nutrition and Health, was the principal investigator in the Ibadan-Nairobi zoonoses study and editor of this special edition of Tropical Animal Health and Production. Grace says that regulations that work for rich countries do not always work for poor countries, and that policies should follow a risk-based approach where decision-makers’ focus is not the bugs present in food but the likely effects on human health. ‘The risks of food-borne diseases’, she says, ‘need also be weighed against the economic benefits and nutrition abundantly supplied by animal products.’

In the absence of evidence, policies are based on the prejudice that urban livestock keeping is unsafe and unmodern, and it is often banned outright. Of course it continues behind hedges and in back alleys, but the imposed illegality drives a rush to the bottom in hygienic practices and investments. When farmers are harassed by authorities and operate in a legal grey area, they have little access to the support they need and little incentive to invest in business improvements.

Thanks in part to previous research on the benefits of urban agriculture, the Government of Kenya has been proactive in posting veterinary, animal production, and crop personnel in major urban centers to lead from the front in championing the development of urban agriculture. The government has also led in the development of the urban agriculture and livestock policy. Involving these civil servants has been key in enabling our research in urban agriculture. This is a good example of government changing its policy to better meet the needs of citizens.

Rapid urbanization, and along with it the urbanization of poverty and food insecurity, raises urgent challenges for the global research and development community. Among them is the need to manage the growing risks of zoonosis associated with urban farming and to improve food safety for the one billion of the world’s poor living in cities, most of whom depend on informal markets instead of more formal government-organized markets or grocery stores.

Informal, or wet markets, exist in many different forms across Africa and Asia but have common characteristics: food escapes effective health and safety regulation; many retailers do not pay tax and some are not licensed; traditional processing, products and retail practices predominate; infrastructure such as water, electricity, sanitation, and refrigeration is lacking; and little support is provided from the public or non-governmental sector. Unsurprisingly, women and the poor are involved most in informal markets.

Applying an innovative research approach known as ‘ecohealth’, the findings of this research contradict some basic assumptions about zoonoses and urban farming and show how livestock keepers in one of Africa’s biggest cities, Nairobi, Kenya, are transforming their livestock and public health practices to combat disease and help feed a city where 60% of the population lives in slums.

But what does it mean in practice? A special edition of 11 papers sets out how ecohealth approaches can make a difference to city health. The researchers base their findings from two case studies. One is in Dagoretti, a Nairobi district of some 240,000 residents, and analyzes the emerging zoonoses cryptosporidiosis, a diarrhoeal disease that is passed from cattle to humans.

Roots and tubers to the fore: Cassava and sweet potato may improve dairy goat production in Tanzania’s drylands, but will women benefit?

Posted on October 9, 2012 by Paul Karaimu

Harrison Rware, an ILRI researcher, listens to Sinayo Taigo, a farmer in Mvomero District, Tanzania during a review of 3-year work plans developed by women in a program that is setting up community-managed breeding programs for dairy goats and introducing improved varieties of cassava and sweet potato in the country (photo credit: ILRI/Deo Gratias Shayo).

Researchers in Tanzania are exploring how small-scale farmers might better integrate production of root and tuber crops, such as cassava and sweet potatoes, with rearing dairy goats to improve the food and nutritional security of their households.

Surprisingly, few programs in Tanzania have yet focused on integrating these crops with small ruminants, such as goats. This is despite the fact that sweet potato and cassava are among the most important root and tuber crops grown by the country’s farmers, most of whom keep goats. Cassava and sweet potato provide human food in periods of hunger, provide feed for ruminant animals (leaf meal from cassava and vines from the sweet potato plant), and can be grown in semi-arid areas.

With farmers, the scientists are setting up community-managed breeding programs for dairy goats and introducing improved varieties of cassava and sweet potato. Both dairy goats and root crops are new to the study region, the Mvomero and Kongwa districts of Morogoro and Dodoma regions, respectively, where project staff distributed Toggenburg and Norwegian improved breeds of dairy goats to 107 farmers in February 2012.

Drought-tolerant varieties of cassava and sweet potato have never before been farmed at large scale in the region and dairy goat keeping has previously been restricted to the wetter areas of the districts. ‘This is changing now,’ says Faustin Lekule, a professor with Sokoine University of Agriculture, ‘because with the use of these crops, we can now introduce dairy goats in dry agro-pastoral areas.’

Led by Tanzania’s Sokoine University of Agriculture and the University of Alberta, in Canada, the project also involves collaboration with the agricultural research institute in Kibaha, the Kongwa and Mvomero district councils and the Foundation for Sustainable Rural Development, a non-governmental organization. The International Livestock Research Institute (ILRI) is serving as knowledge-support partner for the project and is providing expertise on goat production, gender integration, monitoring and evaluation, and assessing food and nutritional security.

‘We’re combining project- and community-based indicators to ensure that farmer decisions guide the project’s implementation,’ said Pamela Pali, a scientist at ILRI who is leading the monitoring and evaluation component of the project. The project is using a web-based monitoring and evaluation system, set up by ILRI’s Research Methods Group, to collect and share information on how farmers are responding to the project’s interventions.

A gender analysis has been applied from the start of the project, including in its research design. ‘We analyzed gender roles, time use, labour allocation and other gender-related factors associated with raising dairy goats and cultivating root crops,’ said Pali. This information was used to refine the distribution of goats and planting materials to households.

Results from the study sites show that few women own goats or have control over the milk produced and sold from dairy goats. As the demand for milk and milk products increases in cities and milk points, men’s role in milk marketing has taken centre stage. ‘But we also know that livestock activities for women in Africa increase with intensification of production’, says Pali. ‘Seasonal and gender differences in livestock activities such as feeding, watering and milking must be well understood so that we avoid the extra work load on women but ensure that their control over the benefits is increased.’

A key input of the project has been capacity building. Both Sokoine University of Agriculture and the agricultural research institute in Kibaha are training farmers how to raise dairy goats.

‘I received a goat in February this year. As a result of the training, I now understand how to feed the animal, construct a better goat house and identify signs of diseases for my goat. This project has improved my farming skills,’ said Subeida Zaidi, a woman farmer in Kongwa District.

Farmers like Zaidi, who keep goats and grow root crops on small plots typically about one-quarter of an acre, both consume the milk produced by their animals at home and will start to sell it to meet their cash needs. Sustainability is built into this project: once a goat produces offspring, its owner gives a female kid to another farmer, thus ‘passing on the gift’, to use the term made popular by the American non-governmental organization Heifer International.

The project’s monitoring and evaluation trainings have helped farmers clarify their objectives, which include increasing the number of goats they keep, the amount of milk their goats produce and the amount of dual-purpose food-fodder root crops they cultivate. The farmers keep records of their milk production, and this information is supposed to be regularly fed into the web-based monitoring and evaluation system. The researchers are using the information generated to put checks against interventions that are likely to impact women and men, especially those that will narrow the gender, nutrition, income and asset gaps between men and women. The information is also helping project staff and the community members to better understand, and make better use of, the informal markets and ‘value chains’ in the region that the farmers use.

In particular, the University of Alberta is using the project to assess the economic impacts of informal markets, trading and gift giving between households at the village level. Knowing how these informal markets for root crops and goats work will broaden understanding of, and inform, ongoing initiatives in the project.

This project, ‘Integrating Dairy Goats and Root Crops Production for Increasing Food, Nutrition and Income Security of Smallholder Farmers in Tanzania’, is funded by Canada’s International Development Research Centre, and Canadian International Development Agency (CIDA).

Taking Stock: Jul 2012 round-up of news from ILRI

Posted on August 1, 2012 by Susan MacMillan

JEFF HASKINS
Last month, we at the International Livestock Research Institute (ILRI) and within CGIAR and the wider agricultural development communities grieved over the sudden loss of American media guru Jeff Haskins, who had spent six years in Africa covering African agriculture news stories for the American PR firm Burness Communications. Haskins, who had just turned 32, died at the Kenya coast on 14 Jul 2012. See online tributes to him from the ILRI News Blog (with links to 25 major news releases and 20 major opinion pieces that ILRI produced with the help of Jeff and his Burness team over the last five years), Pictures of Jeff Haskins (ILRI Pinterest Board), Pictures by Jeff Haskins (ILRI Pinterest Board), Burness Communications Blog, Global Crop Diversity Trust, CGIAR, International Center for Tropical Agriculture, La Vie Verte and Jeff Haskins Facebook page.

MAPPING ZOONOSES
Before his untimely death, Jeff Haskins in early Jul orchestrated major and widespread media coverage of a groundbreaking report by ILRI revealing a heavy burden of zoonoses, or human diseases transmitted from animals, facing one billion of the world’s poor. Some 60 per cent of all human diseases originate in animal populations. The ILRI study found five countries—Bangladesh, China, Ethiopia, India and Nigeria—to be hotspots of poverty and zoonoses. The study also found that northeastern United States, Western Europe (especially the United Kingdom), Brazil and parts of Southeast Asia may be hotspots of ‘emerging zoonoses’—those that are newly infecting humans, are newly virulent, or have newly become drug resistant. The study, Mapping of Poverty and Likely Zoonoses Hotspots, examined the likely impacts of livestock intensification and climate change on the 13 zoonotic diseases currently causing the greatest harm to the world’s poor. It was developed with support from the United Kingdom’s Department for International Development (DFID).

An opinion piece by the main author of the study, ILRI veterinary epidemiologist Delia Grace, wearing her hat as a member of the Dynamic Drivers of Disease in Africa Consortium, appeared this Jul in The Guardian‘s Poverty Matters Blog.

ILRI AWARD
Azage Tegegne, of ILRI and the Improving Productivity and Market Success of Ethiopian Farmers (IPMS) project, was awarded an honorary doctorate of science degree by Ethiopia’s prestigious Bahir Dar University.

ILRI STAFF
ILRI bid goodbye to Bruce Scott, who served ILRI as a director for 13 years, the last decade as director of ILRI’s partnerships and communications department. Bruce is moving only down the road in Nairobi, from Kabete to Westlands, where he is taking up the position of deputy director of a new initiative of Columbia University (USA): Columbia Global Centers ⁄ Africa.

ILRI & FODDER AT RIO+20
We compiled links to ILRI inputs to the Rio+20 conference, including how to ‘turn straw into gold’ with dual-purpose crop residues and, with the International Center for Tropical Agriculture (CIAT), how livestock feed innovations can reduce poverty and livestock’s environmental ‘hoofprint’.

POLICY BRIEF
ILRI produced a policy brief on ‘Preventing and controlling classical swine fever in northeast India‘.

VIDEO INTERVIEWS
We film interviewed ILRI director general Jimmy Smith on ILRI’s evolving new livestock strategy and on ILRI’s role in providing evidence about the ‘bads’ as well as ‘goods’ of livestock production, marketing and consumption. And we interviewed ILRI scientist Joerg Jores on his research results, which, as reported in Scientific American, show that the pathogen that causes cattle pneumonia (CBPP) arose with domestication of ruminants ten thousand years ago, but only ‘heated up’ and began causing disease relatively recently.

VIP VISITORS
An Australian contingent visited ILRI this month and launched a new initiative, the Australian International Food Security Centre, to improve food security in Africa. The centre, which falls under the Australian Centre for International Agricultural Research (ACIAR), will spend USD33.8 million over four years to support food production in Africa as well as in Asia and the Pacific region.

PROJECT NEWS
We reported on the signing of a memorandum of understanding by ILRI and Korea‘s Rural Development Authority (RDA) for laboratory work in Kenya, innovative platforms in an imGoats project in India and Mozambique, and training sessions on controlling zoonoses conducted by the Vietnamese members of an ILRI-led project known by its acronym EcoZD (‘Ecosystem Approaches to the Better Management of Zoonotic Emerging Infectious Diseases in Southeast Asia’).

New ILRI study maps hotspots of human-animal infectious diseases and emerging disease outbreaks

Posted on July 5, 2012 by Susan MacMillan

Map by ILRI, published in an ILRI report to DFID: Mapping of Poverty and Likely Zoonoses Hotspots, 2012.

A new study maps hotspots of human-animal infectious diseases and emerging disease outbreaks. The maps reveal animal-borne disease as a heavy burden for one billion of world’s poor and new evidence on zoonotic emerging disease hotspots in the United States and western Europe.

The new global study mapping human-animal diseases like tuberculosis (TB) and Rift Valley fever finds that an ‘unlucky’ 13 zoonoses are responsible for 2.4 billion cases of human illness and 2.2 million deaths per year. The vast majority occur in low- and middle-income countries.

The study, which was conducted by the International Livestock Research Institute (ILRI), the Institute of Zoology (UK) and the Hanoi School of Public Health in Vietnam, maps poverty, livestock-keeping and the diseases humans get from animals, and presents a ‘top 20’ list of geographical hotspots.

From cyst-causing tapeworms to avian flu, zoonoses present a major threat to human and animal health,’ said Delia Grace, a veterinary epidemiologist and food safety expert with ILRI in Kenya and lead author of the study. ‘Targeting the diseases in the hardest hit countries is crucial to protecting global health as well as to reducing severe levels of poverty and illness among the world’s one billion poor livestock keepers.’

‘Exploding global demand for livestock products is likely to fuel the spread of a wide range of human-animal infectious diseases,’ Grace added.

According to the study, Ethiopia, Nigeria, and Tanzania in Africa, as well as India in Asia, have the highest zoonotic disease burdens, with widespread illness and death. Meanwhile, the northeastern United States, Western Europe (especially the United Kingdom), Brazil and parts of Southeast Asia may be hotspots of ’emerging zoonoses’—those that are newly infecting humans, are newly virulent, or have newly become drug resistant.

The study examined the likely impacts of livestock intensification and climate change on the 13 zoonotic diseases currently causing the greatest harm to the world’s poor.

The report, Mapping of Poverty and Likely Zoonoses Hotspots, was developed with support from the United Kingdom’s Department for International Development (DFID). The goal of the research was to identify areas where better control of zoonotic diseases would most benefit poor people. It also updates a map of emerging disease events published in the science journal Nature in 2008 by Jones et al.[i]

Remarkably, some 60 per cent of all human diseases and 75 per cent of all emerging infectious diseases are zoonotic.

Among the high-priority zoonoses studied here are ‘endemic zoonoses’, such as brucellosis, which cause the vast majority of illness and death in poor countries; ‘epidemic zoonoses’, which typically occur as outbreaks, such as anthrax and Rift Valley fever; and the relatively rare ’emerging zoonoses’, such as bird flu, a few of which, like HIV/AIDS, spread to cause global cataclysms. While zoonoses can be transmitted to people by either wild or domesticated animals, most human infections are acquired from the world’s 24 billion livestock, including pigs, poultry, cattle, goats, sheep and camels.

Poverty, zoonoses and markets
Today, 2.5 billion people live on less than USD2 per day. Nearly three-quarters of the rural poor and some one-third of the urban poor depend on livestock for their food, income, traction, manure or other services. Livestock provide poor households with up to half their income and between 6 and 35 per cent of their protein consumption. The loss of a single milking animal can be devastating to such households. Worse, of course, is the loss of a family member to zoonotic disease.

Despite the danger of zoonoses, the growing global demand for meat and milk products is a big opportunity for poor livestock keepers.

Increased demand will continue over the coming decades, driven by rising populations and incomes, urbanization and changing diets in emerging economies,’ noted Steve Staal, deputy director general-research at ILRI. ‘Greater access to global and regional meat markets could move millions of poor livestock keepers out of poverty if they can effectively participate in meeting that rising demand.’

But zoonoses present a major obstacle to their efforts. The study estimates, for example, that about one in eight livestock in poor countries are affected by brucellosis; this reduces milk and meat production in cattle by around 8 per cent.

Thus, while the developing world’s booming livestock markets represent a pathway out of poverty for many, the presence of zoonotic diseases can perpetuate rather than reduce poverty and hunger in livestock-keeping communities. The study found a 99 per cent correlation between country levels of protein-energy malnutrition and the burden of zoonoses.

Many poor livestock keepers are not even meeting their own protein and energy needs’, said Staal. ‘Too often, animal diseases, including zoonotic diseases, confound their greatest efforts to escape poverty and hunger.’

Assessing the burden of zoonoses
The researchers initially reviewed 56 zoonoses that together are responsible for around 2.5 billion cases of human illness and 2.7 million human deaths per year. A more detailed study was made of the 13 zoonoses identified as most important, based on analysis of 1,000 surveys covering more than 10 million people, 6 million animals and 6,000 food or environment samples.

The analysis found high levels of infection with these zoonoses among livestock in poor countries. For example, 27 per cent of livestock in developing countries showed signs of current or past infection with bacterial food-borne disease—a source of food contamination and widespread illness. The researchers attribute at least one-third of global diarrheal disease to zoonotic causes, and find this disease to be the biggest zoonotic threat to public health.

In the booming livestock sector of developing countries, by far the fastest growing sectors are poultry and pigs.

As production, processing and retail food chains intensify, there are greater risks of food-borne illnesses, especially in poorly managed systems’, said John McDermott, director of the CGIAR Research Program on Agriculture for Nutrition and Health, led by the International Food Policy Research Institute (IFPRI). ‘Historically, high-density pig and poultry populations have been important in maintaining and mixing influenza populations. A major concern is that as new livestock systems intensify, particularly small- and medium-sized pig production, the more intensive systems will allow the maintenance and transmission of pathogens. A number of new zoonoses, such as Nipah virus infections, have emerged in that way.’

Map by Institute of Zoology (IOZ), published in an ILRI report to DFID: Mapping of Poverty and Likely Zoonoses Hotspots, 2012.

Intensification and disease spread
The most rapid changes in pig and poultry farming are expected in Burkina Faso and Ghana in Africa and India, Myanmar and Pakistan in Asia. Pig and poultry farming is also intensifying more rapidly than other farm commodity sectors, with more animals being raised in more concentrated spaces, which raises the risk of disease spread.

Assessing the likely impacts of livestock intensification on the high-priority zoonoses, the study found that livestock density is associated more with disease ‘event emergence’ than with overall disease burdens. Both the northeastern United States and Western Europe have high densities of livestock and high levels of disease emergence (e.g., BSE, or ‘mad cow’ disease, and Lyme disease), but low numbers of people falling sick and dying from zoonotic diseases. The latter is almost certainly due to the relatively good disease reporting and health care available in these rich countries.

Bovine tuberculosis is a good example of a zoonotic disease that is now rare in both livestock and human populations in rich countries but continues to plague poor countries, where it infects about 7 per cent of cattle, reducing their production by 6 per cent. Most infected cattle have the bovine form of TB, but both the human and bovine forms of TB can infect cows and people. Results of this study suggest that the burden of zoonotic forms of TB may be underestimated, with bovine TB causing up to 10 per cent of human TB cases. Human TB remains one of the most important and common human diseases in poor countries; in 2010, 12 million people suffered from active disease, with 80 per cent of all new cases occurring in 22 developing countries.

Massive underreporting

We found massive underreporting of zoonoses and animal diseases in general in poor countries’, said Grace. ‘In sub-Saharan Africa, for example, 99.9 per cent of livestock losses do not appear in official disease reports. Surveillance is not fulfilling its purpose.’

The surveillance lacking today will be even more needed in the future, as the climate changes, she added. Previous research by ILRI and others indicates that areas with increased rainfall and flooding will have increased risk of zoonoses, particularly those diseases transmitted by insects or associated with stagnant water or flooding.

The main finding of the study is that most of the burden of zoonoses and most of the opportunities for alleviating zoonoses lie in just a few countries, notably Ethiopia, Nigeria, and India. These three countries have the highest number of poor livestock keepers, the highest number of malnourished people, and are in the top five countries for both absolute numbers affected with zoonoses and relative intensity of zoonoses infection.

‘These findings allow us to focus on the hotspots of zoonoses and poverty, within which we should be able to make a difference’, said Grace.

Milk markets as ‘the great equalizer’ in East Africa?

Posted on May 26, 2012 by Paul Karaimu

Remarkably, more than 80 per cent of the milk produced and sold in Kenya comes from small-scale players, typically farmers raising one or two dairy cows on small plots of land and milk hawkers plying their trade on bicycles on streets and in villages.

The fast-growing dairy sector in this East African country could help tens of thousands of people climb out of poverty. But this will require supporting small-scale milk producers and traders in gradually entering the country’s formal milk markets.

Until recently, Kenya’s informal milk producers and traders were harassed rather than supported by officials because they were unregulated and were perceived to be a threat to public health.

A chapter in a new book, Towards priority actions for market development for African farmers, describes how Kenya’s small milk producers and sellers are being integrated into formal dairy markets. Authors Amos Omore and Derek Baker, from the International Livestock Research Institute (ILRI), say that what was needed was ‘recognizing and embracing’ the big contributions of dairy’s informal producers and traders and the potential role played by the informal milk markets in fighting poverty. According to the researchers, the removal of policy barriers to allow price-based competition to govern milk trade is enabling this informal dairy industry to significantly improve the welfare of the poor.

Using lessons and examples from a highly collaborative research and development Smallholder Dairy Project, the authors point out that training and certifying small-scale milk traders helps draw the informal milk producers and traders into a more ‘formal’ trading environment. This training also raises consumer confidence by improving and guaranteeing the quality of milk produced for market. With this training, which also teaches business and entrepreneurial skills, the small market players are increasing their incomes as well as milk consumption among poor communities.

‘This dairy project was instrumental in bringing about “mind-set and policy changes” and an impact on the profits made by milk producers in Kenya,’ say Omore and Baker. ‘It also provided a new model of incorporating these small producers into the formal sector.’

Carried out between 1997 and 2005, the Smallholder Dairy Project was led by Kenya’s Ministry of Livestock and Fisheries Development and implemented by ILRI and the Kenya Agricultural Research Institute. It was funded by the UK Department for International Development.

Kenya’s dairy industry, one of the largest in Africa, is supported by over 1.8 million mostly small-scale cattle producers who at the time of implementing the Smallholder Dairy Project supplied over 86 per cent of the country’s milk through direct milk sales from producers to consumers and from dairy farmer groups and over 40,000 small-scale farmers.

The chapter argues that small-scale milk traders trained and certified by the Kenya Dairy Board improved their hygienic practices in milk production and handling. These efforts have brought about ‘direct and sustainable benefits’ for dairy-dependent livelihoods, including making more milk available in the market and higher prices. More licensed small-scale vendors now to operate in the country contributing to more competitive prices that encourage farmers to produce more milk.

The success of the dairy project in mainstreaming Kenya’s the informal milk producers into Kenya’s dairy industry led to a revision of the country’s licensing processes, which then began to start recognizing these informal milk sellers. A 2004 dairy policy change paved the way for significant increases in the number of traders adopting milk testing methods, greater enforcement and compliance in milk quality control and an on-going regional harmonization of dairy policies and standards aiming to transform informal milk markets in Rwanda, Tanzania and Uganda along the lines of the Smallholder Dairy Project in Kenya.

For the tens of thousands of small milk producers in Kenya, these policy changes have made a great difference. Evidence suggest that without the Smallholder Dairy Project, these benefits would have taken another two decades to come to small-scale dairy sector players.

Animal plagues: ‘The lethal gift of livestock’

Posted on May 2, 2012 by Susan MacMillan

List of reported bird flu outbreaks from 11 May through 27 August 2005 (map on Flickr by Brooke Ganz/Asparagirl).

Two veterinary epidemiologists working at the International Livestock Research Institute (ILRI) recently published a fascinating look at the state of ‘livestock plagues’ that can, and regularly are, transmitted to human populations.

The two authors are John McDermott, who has since moved from ILRI to the International Food Policy Research Institute, where he leads a new CGIAR Research Program on ‘Agriculture for Better Nutrition and Health’, and Delia Grace, who remains at ILRI and leads the health components of this new program.

Introduction to this ILRI essay
‘Since the widespread domestication of animals in the Neolithic era, 10,000–15,000 years before the Common Era (CE), human livelihoods have been inextricably linked with the livestock they keep. Domesticated animals must have been among the most valued assets of ancient humans: walking factories that provided food, fertiliser, power, clothing, building materials, tools and utensils, fuel, power and adornments. Inevitably, the innovations of crop cultivation and food storage that allowed people to settle and live in high numbers and densities also increased the number of animals kept, density of livestock population and the intimacy of human-animal interactions. Pathogens responded, undergoing intense genomic change to seize these dramatically expanded opportunities.

Epidemics of highly contagious and lethal disease emerged, as livestock and people reached the critical population sizes needed for acute infections to persist. Diseases also jumped species from animal to humans: the lethal gift of livestock.

‘This chapter discusses which livestock epidemics are likely to constitute a disaster and why. . . .

Conclusion of the ILRI chapter
‘The struggle with epizootics continues and has even intensified in recent times. Population-decimating animal plagues, such as contagious bovine pleuropneumonia, peste des petits ruminants, swine fever, Newcastle disease and avian influenza, continue to have lethal and devastating impacts on livestock and livelihoods.

Livestock plagues are also shifting and emerging while climate change, urbanisation, migrations, genetically modified crops and rapid land use changes are examples of wild cards which could alter the present distribution for the disease dramatically for the worse.

The declaration of an era of epidemics, though, might be premature. In richer countries, dependence on livestock is low, resources exist to effectively control disease and non-communicable diseases associated with modern farming systems (such as lameness and reproductive problems) production pose the greatest problem to animal health.

‘In the developing world, the situation is different. Many people depend on animal agriculture: 700 million people keep livestock and up to 40 per cent of household income depends on livestock. Animal and human disease outbreaks are far more frequent, both for infections well controlled elsewhere and for emerging diseases.

In the poorest countries in Africa, livestock plagues that were better controlled in the past are regaining ground. Paradoxically, the fear of epizootics is much higher among the worried well in rich countries, who are highly concerned about the diseases they are very unlikely to fall sick or die of.

Thankfully this enlightened self-interest is providing more support for control of epizootics in poor countries. But it appears that while the centralised control of livestock plagues is effective (albeit, at high-cost) in richer countries, it struggles in the poorest. New approaches are not only needed but need to be rapidly tested and made available. What is required now is the vision and courage to transcend sectoral and conventional veterinary approaches and apply innovations to these urgent problems.’

Section one situates hazards and disasters in their broad political, cultural, economic, and environmental context. Section two contains treatments of potentially damaging natural events/phenomena organized by major earth system. Section three critically reviews progress in responding to disasters including warning, relief and recovery. Section four addresses mitigation of potential loss and prevention of disasters under two sub-headings: governance, advocacy and self-help, and communication and participation. Section five ends with a concluding chapter by the editors.

New markets book showcases livestock insurance scheme that is helping Kenyan herders protect their marketable assets

A new book on markets development for African smallholder farmers has highlighted a pioneering livestock insurance project as a key innovation that could enable African farmers reduce their losses in crop and livestock production.

The new publication: Towards priority actions for market development for African farmers, says lowering production and efficiency losses in agricultural production and improving agricultural markets will, among other actions, ‘level the playing field for smallholder farmers’ and support human and economic development in Africa. The books calls for the ‘right mix’ of policy and investments to not only ‘strengthen African policy expertise’ but also encourage ‘a more diverse array of investments and initiatives, including those initiated by the private sector.’

One such initiative that brings together private and public sector actors to support African agriculture is an Index-Based Livestock Insurance project in Kenya. The project is featured in a chapter in the new book.

Started in 2010 by the International Livestock Research Institute (ILRI) in partnership with UAP insurance, Equity Bank, Cornell University and the Index Insurance Innovation Initiative program at the University of California at Davis, the Index-Based Livestock Insurance project provides livestock insurance against forage losses to over 2500 households in Kenya’s Marsabit District. Freely available satellite imagery is used to assess conditions of pastures. When pasture vegetation is reduced to a level below a specified threshold, the insurance company pays herders who bought insurance. Yearly premiums cost USD100 for 6-8 animals.

Pastoral livestock sectors are at the heart of agricultural markets in Africa. Kenya’s livestock industry, for example, is estimated to be worth about USD800 million per year and produces most of the meat consumed in the country and is critical to the country’s food security. Research by ILRI shows that long-term solutions to food security in Kenya and other countries in the Horn of Africa need to support livestock herding. Pastoral systems are critical for the survival of livelihoods here and offer the most efficient way of managing the region’s large arid and semi-arid lands.

This insurance scheme is currently being piloted in other parts of Kenya and in Ethiopia. In late 2011, 600 livestock keepers insured through the project received insurance payments for vegetation losses arising from the drought that struck the Horn that year. The project is also now making use of mobile phones to widen its impact in remote communities.

Notes:

The new book, which is published by ILRI and the Alliance for a Green Revolution in Africa (AGRA), warns that ‘it will not be enough to simply produce more food from the fields and grazing lands of Africa.’ More effort is needed to create better markets and improve access to these markets’ especially in remote regions.

The book describes the outcomes of an international conference held in Nairobi three years ago that examined the ‘priority actions’ that if taken could speed up the development of African agricultural markets.

Authors of the markets books recommend enhancing markets for poor people, improving market information, lowering transaction costs associated with trading and adding value to farm produce by upgrading value chains and processing mechanisms.

Five ways to enhance agricultural markets in hungry regions of East and West Africa

With food shortages being predicted for dryland communities in both East and West Africa this year, it seems an appropriate time to revisit a major way African experts see that the continent can feed itself: Get Africa’s markets working.

Three years ago, 150 of the world’s leading market experts gathered in Nairobi, Kenya, to document the best ways to drive agricultural market development in sub-Saharan Africa. Both the proceedings of this international conference, Towards Priority Actions for Market Development for African Farmers, held 13–15 May 2009, and a synthesis of its outcomes, Priority Actions for Developing African Agricultural Markets, were published last year by ILRI and the Alliance for a Green Revolution in Africa (AGRA).

The synthesis of this major African markets conference begins by referring to the sudden escalation in food costs that began in late 2010 and persisted into 2011—the second time in only three years that rapid food price rises, caused by a combination of production shortfalls and market failures causing dramatic gaps between supply and demand, rocked developing countries worldwide. With Africa’s long-term struggle with food insecurity, this continent and its economies and people are especially vulnerable to any sudden rise in food prices.

Even before the price shocks of 2008 and 2011, expert opinion had begun to coalesce on the centrality of agriculture in addressing African hunger and poverty. Much of the discussion has focused on increasing agricultural productivity through improved crop varieties and animal breeds, along with increased access to inputs and veterinary services, to boost farm yields. And, indeed, with crop and livestock yields on African farms typically a fraction of that in other regions, there appear to be big opportunities for new breadbaskets and milk sheds emerging across the continent.

But it will not be enough to simply produce more food from Africa’s fields and grazing lands. First, most Africans—including most smallholder, and even subsistence farmers—are net purchasers rather than growers of food. Also, as more and more people migrate from rural to urban areas, more and more Africans are relying on markets to meet their food needs. And because most rural as well as urban Africans spend a significant proportion of their income on food, even modest increases in food prices can tip millions of them into poverty.

Efficient and vibrant agricultural markets would help. But Africa’s agricultural markets suffer from a dearth of processing and storage facilities, pricing information, smallholder credit, and transport. These create inefficiencies that both raise prices for consumers and restrict sales opportunities for farmers, who are stopped from selling their food surpluses in nearby food-deficit regions.

Five recommendations
The following five recommendations, highlighted here for their special pertinence to the drylands of East and West Africa, are presented in case studies published in the ILRI-AGRA markets book:
1 Support village seed trade in semi-arid areas
2 Manage pastoral risk with livestock insurance
3 Employ ICTs to raise smallholder income
4 Embrace informal agro-industry
5 Encourage intra-regional trade

Details of these recommendations follow.
1 Support village seed trade in semi-arid areas
Section 2 of the proceedings volume, Seed and Fertilizer Markets, includes a case study of the utility of Tapping the potential of village markets to supply seed in semi-arid Africa in Mali and Kenya. This paper, written by Melinda Smale, (Oxfam America), Latha Nagarajan, Lamissa Diakité, Patrick Audi (ICRISAT), Mikkel Grum (Bioversity International), Richard Jones (ICRISAT) and Eva Weltzien (ICRISAT), shows that village markets have the potential to supply high-quality pigeon pea and millet seed in semi-arid areas of Kenya and Mali, respectively.

The problem: Periods of seed insecurity occur in remote, semiarid areas when spatially covariate risk of drought is high and many farmers fall short of seed. In these remote environments, seed systems are typically informal, and farmers rely on each other for locally adapted varieties. They are not reliable clients for private seed companies because they purchase seed irregularly. Less improved germplasm has been developed for semiarid environments because of the high costs of breeding and supplying seed—a situation that has worsened with decreasing public funding for agricultural research. In the Mali study, village markets assure a supply of seed of identifiable, locally adapted, genetically diverse varieties as a final recourse in a risky environment where there are as yet no reliable formal channels, for which competitive varieties have not yet been bred, and the potential of agro-dealers to supply certified seed has not yet been exploited. In the Kenya study, well-adapted varieties have been bred, but no formalized channels of seed provision exist for pigeon pea and agro-dealers are active in selling improved varieties of maize and vegetables. In both studies, farm women are major seed trade actors. Interestingly, the characteristics of seed vendors and the locations of seed programs—not the price of seed—tend to determine the quantities of seed sold. The authors argue for strengthening and linking both formal and informal systems for non-hybrid dryland crops.

Some solutions: Several approaches piloted recently are potential candidates for improving the supply of good-quality seed on a large scale.

The West Africa Seed Alliance (WASA) and the Eastern and Southern Africa Seed Alliance (ESASA) work to help local entrepreneurs expand existing seed companies and create new ones.

Since private seed companies do not yet operate in the sorghum- and millet-based systems of the Sahel, where state agencies are underfunded, scientists at the International Crops Research Institute for the Semi-Arid Tropics (lCRISAT) have tested several models that draw on the comparative advantages of farmer organizations.

2 Manage pastoral risk with livestock insurance
Section 3 of the ILRI-AGRA markets proceedings, Strengthening Finance, Insurance and Market Information, has two case studies of particular relevance to the food problems facing the drylands of West and East Africa.

First is a report on Insuring against drought-related livestock mortality: Piloting index-based livestock insurance in northern Kenya, written by ILRI’s Andrew Mude and his partners Sommarat Chantarat, Christopher Barrett, Michael Carter, Munenobu Ikegami and John McPeak.

The problem: Climate extremities pose the greatest risks to agricultural production, with droughts and floods not only causing crop failures but also forage and water scarcity that harms and kills livestock. The number of droughts and floods has risen sharply worldwide in the last decade, with disaster incidence in low-income countries rising at twice the global rate. In much of rural Africa, where water harvesting, irrigation and other similar water management methods are under developed, the impacts of climate change are expected to be especially pernicious.

A solution: In the last several years, new ways to manage weather-related agricultural risk have been developed. Of these, index-based insurance products represent a promising and exciting market-based option for managing climate-related risks faced by poor and remote populations.

This paper describes research to design commercially viable index-based livestock insurance for pastoral populations of northern dryland Kenya, where the risk of drought and drought-related livestock deaths is high.

The analysis indicates a high likelihood of commercial sustainability in the target market and describes events leading up to the pilot launch in Marsabit District in early 2010. The paper concludes that this insurance tool has largely succeeded in helping Marsabit’s livestock herders better manage their risk of drought. Growing interest from both commercial and development partners is helping to take this instrument to other arid and semi-arid districts in Kenya and other countries and regions.

3 Employ ICTs to raise smallholder income
The same Section 3 of the ILRI-AGRA book offers a case study from West Africa, written by Kofi Debrah, coordinator of MISTOWA, supporting the Role of ICT-based management information systems in enhancing smallholder producers’ incomes.

The problem: Smallholder African farmers typically have little access to reliable marketing outlets in which to sell their surplus produce at remunerative prices. Furthermore, their ability to respond quickly to market opportunities is constrained by lack of labour, credit, market information and post-harvest facilities. As a result, West African farmer incomes from agriculture are low and variable and little agricultural produce is traded in the region.

A solution: A project funded by the United States Agency for International Development (USAID), ‘Strengthening Regional Networks of Market Information Systems for Traders’ Organizations in West Africa’ (MISTOWA), helped build a private-public partnership to develop and deploy an ICT-based market information system that improved farmers’ access to markets. Some 12,500 agricultural producers and traders from 15 West African countries benefited from the project, with the beneficiaries reporting USD4,080 in benefits, or USD4.33 per dollar of donor funds invested.

Evidence from the beneficiaries suggests that access to real-time market information provides smallholder farmers with incentives for investing in agriculture.

4 Embrace informal agro-industry
Section 4 of the markets book, High-Value Commodities and Agroprocessing, includes a paper by ILRI scientists Amos Omore and Derek Baker on Integrating informal actors into the formal dairy industry in Kenya through training and certification.

The problem: Throughout the developing world, most food produced by smallholder farmers is delivered and processed by an ‘informal’ agro-industry, which is the principal source of food for most poor consumers and a major source of employment of poor people as traders and service providers. In spite of this, agro-industrial policy has historically tended to displace this informal sector with a formal one featuring relatively large-scale and capital-intensive production and marketing. Other policy concerns, such as public health and municipal planning, have further selected against informal agribusiness, particularly livestock’s informal agro-industry.

A solution: This paper presents a case study of interventions in the Kenyan informal milk industry that led to changes in dairy policy that in turn reduced poverty levels in the East African country. The paper identifies the informal agribusiness sector as fertile ground for alleviating poverty and supporting vulnerable groups.

Policies do well to embrace informal agro-industry, the research indicates, while helping it transform itself into a more formal industry.

The ILRI scientists show that the informal dairy industry can respond well to consumer demand for quality, particularly for safe food, and, when unjustified policy barriers are removed, can compete well when price alone becomes the basis of competition. These achievements support much conjecture in the development literature about the centrality of markets, and access to them, for pro-poor development and the idea that pro-poor markets rely heavily on policy and institutional change. The lessons of this project are being transferred to other informal commodity sectors (goats, beef cattle and pigs) in Africa and Asia and the policy changes seen in the Kenya dairy project have been adopted across the East African region.

5 Encourage intra-regional trade
Section 6 of the markets book, Encouraging Regional Trade, includes a paper on The impact of non-tariff barriers on maize and beef trade in East Africa. The paper is written by Joseph Karugia (ILRI and ReSAKSS-ECA), Julliet Wanjiku (ILRI and ReSAKSS-ECA), Jonathan Nzuma, Sika Gbegbelegbe, Eric Macharia, Stella Massawe, Ade Freeman, Michael Waithaka and Simeon Kaitibie.

The problem: In 2004, the East African Community member states established an East African Community Customs Union, committing them, among other things, to eliminate non-tariff barriers to facilitate increased trade and investment flows between member states and to create a large market for East African people. However, several such trade barriers are still applied by member states and there exists little reliable information about how, and how much, these non-tariff barriers are actually hurting regional trade. This study identified the existing non-tariff barriers on the trade of maize and beef in East Africa and quantified their impacts on trade and citizen welfare in the region. The study found that the main types of non-tariff barriers within the three founding members of the East African Community (Kenya, Tanzania and Uganda) are similar and include administrative requirements, taxes/duties, roadblocks, customs barriers, weighbridges, licensing, corruption and transiting.

Some solutions: The study recommends taking a regional approach to exploit economies of scale by eliminating non-tariff barriers, since they are similar across the member countries and across commodities. Specific policy recommendations include streamlining administrative procedures at border points to improve efficiency; speeding up implementation of procedures at point of origin and at the border points; and implementing monitoring systems to provide feedback to relevant authorities on progress in removing unnecessary barriers to trade within East and Central Africa. The welfare analysis of the study shows that abolishment or reduction of the existing non-tariff barriers in maize and beef trade increases trade flows of maize and beef within the East African Community, with Kenya importing more maize from both Uganda and Tanzania and Uganda exporting more beef to Kenya and Tanzania. As a result, positive net welfare gains are attained for the entire East African Community maize and beef sub-sectors.

These findings give compelling evidence in support of the elimination of non-tariff barriers within the East African Community Customs Union.

Making Asian agriculture smarter

Posted on April 20, 2012 by Susan MacMillan

Last week, coming on the heels of a Planet Under Pressure conference in London, which set out to better define our ‘planetary boundaries’ and to offer scientific inputs to the Rio+20 United Nations sustainable development conference this June, a group of leaders in Asia—comprising agriculture and meteorology chiefs, climate negotiators and specialists, and heads of development agencies—met to hammer out a consensus on ways to make Asian agriculture smarter.

The workshop, Climate-smart agriculture in Asia: Research and development priorities, was held 11–12 April 2012 in Bangkok. It was organized by the Asia-Pacific Association of Agricultural Research Institutes; the CGIAR Research Program on Climate Change, Agriculture and Food Security; and the World Meteorological Organization.

This group set itself three ambitious tasks: To determine the best options (1) for producing food that will generate lower levels of greenhouse gases, which cause global warming; (2) for producing much greater amounts of food, which are needed to feed the region’s rapidly growing and urbanizing population; and (3) for doing all this under a changing climate that, if farming and farm policies don’t change, is expected to reduce agricultural productivity in the region by anywhere from 10 to 50 per cent over the next three decades.

The workshop participants started by reviewing the best practices and technologies now available for making agriculture ‘climate smart’. They then reviewed current understanding of how climate change is likely to impact Asian agriculture. They then agreed on what are the gaps in the solutions now available and which kinds of research and development should be given highest priority to fill those gaps. Finally, they developed a plan for filling the gaps and linking scientific knowledge with policy actions at all levels.

On the second of this two-day workshop, the participants were asked to short-list no more than ten key areas as being of highest priority for Asia’s research and development communities.

This exercise tempted this blogger to suggest ten suitable areas in the livestock sector.

(1) Lower greenhouse gas emissions from livestock through adoption of improved feed supplements (crops residues) that reduce greenhouse gas emissions.

ILRI adopts strategy and plan to mainstream approaches for gender equity in livestock development

Posted on March 23, 2012 by ILRIComms

This month, management of the International Livestock Research Institute (ILRI) adopted a ‘Strategy and plan of action to mainstream gender in ILRI’.

The document was developed by a task force led by Jemimah Njuki, leader of ILRI’s Poverty, Gender and Impact team.

This strategy and action plan define the role that ILRI will play to stimulate and facilitate efforts, both in-house and with partners, to take advantage of opportunities to promote gender equality and equity within the livestock subsector and the agriculture sector in general.

It has three main objectives:

To promote equality of opportunity and outcomes between women and men in the livestock subsector at local, national, regional and global levels;
To increase the quality, efficiency and impacts of ILRI’s work in livestock development;
To ensure that equality, equity and rights are respected across gender, that there is good gender representation in ILRI staffing and decision-making positions and that there is active and balanced participation by both women and men in ILRI’s work.

The strategy and action plan to mainstream gender in ILRI embodies ILRI’s strong commitment to efforts to promote gender equality and women’s empowerment—Jimmy Smith, ILRI director general

The action plan is designed to contribute to the ongoing development of a new strategy for ILRI. To make it operational, Jimmy Smith called on ILRI staff to ‘work together to translate this commitment into actions that make a difference on the ground’.

The finalization of the strategy is one of the last actions in ILRI by Jemimah Njuki, who departs the institute at the end of March 2012. Her energy and commitment across ILRI will be missed. Read more about her work, and that of her team, on the ‘agrigender blog‘.
