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.

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.

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? . . .’

As the cooking pot turns: Staple crop and animal foods are being ‘recalibrated’ for a warmer world

Posted on November 1, 2012 by Susan MacMillan

CGIAR has just published a really useful snapshot of the world’s major food crops, animals and tree and water resources and what is likely to happen to them in the face of climate change, the effects of which on food production will require reexamining what’s in the cooking pot, especially in regions where people already do not get enough to eat. Above, a worker on a small farm in Limuru, Kenya, pushes maize stalks (after their cobs have been harvested) through a pulverizer before feeding the stover to the cows; this is one way small-scale farmers can improve their dairy cow feeding and milk yields while reducing the amount of methane their cows generate per unit of milk produced. (Photo on Flickr by Luigi Guarino.)

CGIAR, the world’s leading international agricultural-research-for-development organization, has just done something really useful. It has published a snapshot of how climate change is likely to affect key food crops and livestock farming and natural resources in poor countries, where these staple foods and resources remain the backbone not only of food security but also of national economies. What happens to maize and wheat and rice and cattle and goats and sheep and trees and water, for example, will foretell what happens to the 1 billion people living in severe poverty today.

This snapshot summarizes the state of knowledge on 21 CGIAR crop commodities as well as on the ‘living’ livestock assets of the poor and the water and tree resources on which they depend. The study, Impacts of climate change on the agricultural and aquatic systems and natural resources within the CGIAR’s mandate, should help decision-makers at all levels prepare better for future food production on our warming planet.

The summaries, written by scientists at 14 of the 15 CGIAR centres, outline the importance of each commodity for food and nutrition security, its biological vulnerability to climate change, and the likely socio-economic vulnerability of the people affected.

The study shows points up some surprising gaps in our knowledge. For example, crops like cassava and yam, which make critically important contributions to the food security of millions of people and are highly climate-resilient, have been little studied in relation to a changing climate. We also know little about how multiple stressors of animals and plants may combine. We also have big knowledge gaps about likely impacts of climate change on weed, pest and disease complexes. We need this information to help identify and evaluate the trade-offs and synergies of particular climate change adaptation and mitigation options in different places.

A few things are already for certain. We must develop hardier varieties of maize, rice and wheat—the three main food staples around the world—quickly to avoid declines in their yields. And the common sources of protein—livestock, fish, and even soybeans—all face difficulties in adapting to the new normal.

Crops and animals till now neglected by major research initiatives, and now considered ‘old-fashioned’ by many, are likely to play an increasingly important role on global food production once again. Drought-resistant camels and goats, ‘famine foods’ such as heat-tolerant cassava and millet, and dual-purpose crops such as protein-rich cowpea (aka black-eyed peas) and groundnut that feed people and animals alike are all likely to come back to the fore in regions with drying or more unpredictable climates.

In some drying regions, smallholders will be forced to switch from crop growing to livestock raising, and/or from raising dairy cows to raising dairy or other goats. This matters to many. As the new CCAFS policy brief reports: ‘In South Asia and sub-Saharan Africa, for example, nearly one billion people living on less than two dollars per day keep livestock; two-thirds of those are women. Fisheries and aquaculture support an additional half-billion people around the world. There is no easy answer for adapting these sectors to changing climates.

But the benefits to people from eating fish and animal protein—as well as raising livestock for their livelihoods—will not evaporate as the planet warms; answers must be found in securing their continued availability.’

While the news seems grim, adaptation is possible. Recent CCAFS research in Africa found that farmers are already adapting to climate change. Some 34% of the farmers interviewed in Africa, for example, have reduced their livestock herd sizes and 48% are managing their feed resources better. The better livestock diets also lower livestock methane emissions per kilogram of milk or meat produced. On the other hand, only 25% of the farmers interviewed have begun using manure or compost to improve their soils and only 10% have begun to manage or store agricultural water.

For more information, visits the CCAFS blog page on Recalibrating food production in a changing climate—What do we know and what can be done?

Read a new policy brief by CCAFS that outlines the challenges required in feeding the estimated 9–10 billion people who will live in this world by 2050. In the brief, the need for a complete recalibration of what crops we grow and animals we raise around the world is detailed, as climate change will bring challenges in weather, water use, and increased pests and diseases of crops and animals alike.

The policy brief is based on a new CCAFS working paper. Read the paper by Philip Thornton and Laura Cramer (eds.). 2012. Impacts of climate change on the agricultural and aquatic systems and natural resources within the CGIAR’s mandate. CCAFS Working Paper 23. Copenhagen, Denmark: CGIAR Research Program on Climate Change, Agriculture and Food Security.

This report was co-edited by ILRI scientist Phil Thornton, who is a scientist at the International Livestock Research Institute (ILRI) who also coordinates one of CCAFS’ research groups. CCAFS is a global partnership launched in 2011 between the research centres of CGIAR and the Earth System Science Partnership. CCAFS facilitates and integrates thematic work across multiple CGIAR Centres and other global, regional and local partners. Its key target groups are resource-poor agricultural producers, and rural and urban consumers of food, in low-income and middle-income countries in the tropics and sub-tropics.

Philip Thornton explains about CCAFS: ‘There are many other examples of the way in which CCAFS is working across disciplines and mandates, and across temporal and spatial scales. These include linking to modelling communities from different fields such as crop modelling and global integrated assessment modelling, and partnering with organisations with skills in the development and provision of downscaled models, decision-tools and datasets that provide the necessary granularity for national and sub-national planning. As well as linking across scientific disciplines, CCAFS recognizes the need to span boundaries across research and policy domains. To link knowledge and action entails involvement of policy-makers in all stages of the research cycle, and an understanding of policy as dynamic and polycentric across the public, private and civil society sectors.’

KARI agricultural innovations big hit with young smart business farmers: ‘Those are OUR people’

Posted on October 30, 2012 by Susan MacMillan

The 13th Biennial Scientific Conference and Exhibition at the Kenya Agricultural Research Institute (KARI) took place last week at KARI’s headquarters in Nairobi’s leafy suburb of Loresho.

This correspondent—enamoured of the sea of white tents erected across KARI’s rolling green lawns to showcase hundreds of exhibitors of ‘Agricultural Products, Technologies & Innovations’—never actually made it to the proceedings of the conference itself. But if the conference was anything like the exhibits, it must have been a great success.

My organization, the International Livestock Research Institute (ILRI), tried to distinguish its exhibit on livestock forage research and capacity building from the hundreds of other tents just like it with decorations of African artefacts—wooden bowls, woven baskets and traditional cloths and the like—as well as safari chairs inviting passersby to come inside for a conversation. So successful were we that many people upon entering the ILRI tent promptly asked to buy some of the display items (and were promptly disappointed when we told them they weren’t for sale.) The big cattle and camel bells were also a big hit, with the visitors having to explain to ILRI staff the difference between the bell sounds appropriate for cows and those for bulls!

We were at KARI to promote opportunities for young Kenyan scientists to train at ILRI, the headquarters of which are located just a 15-minute drive from KARI. And we showcased our collaborative research with KARI scientists, including Solomon Mwendia, on disease-resistant varieties of Napier grass, aka ‘elephant grass’, on which so many Kenyan smallholder farmers depend for feeding their milk cows.

Visitors showed great interest in ILRI printed materials about improved forages and feeds (lab lab, oats, vetch), seed samples and Napier grass cuttings and leaves, and a research-based feed assessment tool for selecting appropriate feeds for different regions.

‘The demand for information was huge’, says Alexandra Jorge, who heads ILRI’s Forage Genebank, in Addis Ababa, Ethiopia, and came down to Nairobi to answer questions and provide expertise at KARI’s week-long event. ‘We had questions about the best feeds for dairy goats, how to maximize forage production for feeding dairy cows, the best methods for raising pigs, the best breeds of chickens to keep, how to transition to stall-fed (‘zero grazed’) dairy animals, how to start hydroponic and screen-house forage production, and what climate change is likely to change in Kenyan agriculture—and what livestock farmers can do now to cope with it.’

‘I really enjoyed participating in this exhibit,’ Jorge says ‘having real contact with our users and clients and chatting about their challenges and projects. It made me think hard about what we researchers do and the impact and benefits we can bring to farmers. It also made me realize how little I know about the work that many colleagues are doing and that we should make this information much more available.’

‘It was amazing to see the amount of interesting and innovative work KARI and many Kenyan universities are doing. Many people had stories to share, or tasty food, like the amazing sorghum sausages that taste just like meat!’ If you’re planning similar events, you may find the services offered by https://eventmanagementservices.co.uk/corporate-events/award-ceremony-event-management to be a great way to recognize outstanding achievements.

ILRI research manager Sandra Rwese was most impressed with the number of young entrepreneurs at this event looking for agricultural innovations and good ideas. ‘Scores of youth finding few jobs in urban areas appear to be calling city life quits and heading to rural farming villages. The numbers of these young new farmers that I met at the KARI event are much larger than I’d expected. This young generation is clearly keen on taking agriculture and livestock farming to the next level. In fact, the success of events like these highlights the importance of event management for award ceremonies, which can inspire and recognize the achievements of such visionary individuals.’

Jane Gitau, a communications officer at ILRI, agrees. ‘Many of the visitors to ILRI’s tent inquiring about better methods of livestock keeping appeared to be in their thirties and early forties. They wanted information to take away with them; they wanted to learn more efficient methods of farming. It was refreshing to witness this drive to make agriculture a knowledge-based business. As we explore these innovations, incorporating technology such as effective video conferencing tools can significantly enhance communication and collaboration among young farmers interested in improving their practices. Additionally, implementing SEO services can help these farmers access valuable online resources and reach a wider audience, fostering growth and sharing of agricultural knowledge. For more insights, check out this resource at https://corporateeventproduction.co.uk/video-conferencing/.’

‘Walking from booth to booth’, Gitau said, ‘I was amazed to see all that KARI had to offer from its 22 centres countrywide, from Kibos to Kiboko, Muguga to Thika, each with a different mandate in agricultural research. Staff from KARI’s Kiboko Research Station, located about 150 km southeast of Nairobi and the institute’s drylands station, exhibited various imported and hybrid rangeland grasses they are trialing. KARI’s Muguga Station was exhibiting some of Kenya’s important plant and livestock genetic resources. And an improved rice variety grown under irrigation at Kibos, in western Kenya, was on display, along with rice flour, rice cakes, rice doughnuts and rice cookies!’

Finally, Gitau remarked on the close connections KARI has to its constituency. ‘Those of us manning the ILRI booth often directed visitors to the many KARI booths to get their specific farming and livestock keeping questions answered. These people sought practical help and region-specific recommendations we didn’t have’, Gitau said. ‘When I asked people if they knew where to find KARI, I several times got the reply, ‘Hao ni watu wetu’, colloquial Swahili for, “Those are our people”.

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.

ILRI scientist Delia Grace is interviewed by BBC and AllAfrica.com before the start of a journalist tour of urban livestock farmers in Nairobi that ILRI organized on 21 Sep 2012 (photo credit: ILRI/Paul Karaimu).

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.

Participatory radio’s power in driving adoption of farming technologies: Lessons from Farm Radio International

Posted on October 10, 2012 by Paul Karaimu

A recent study by Farm Radio International shows participatory radio campaigns that use local languages, allow farmer participation and that highlight tested and available technologies are particularly useful in hastening the adoption of new technologies by small-scale farmers in Africa.

In an experiment carried out between 2007 and 2011 under the African Farm Radio Research Initiative, Farm Radio International tested a participatory radio campaign in in Ghana, Malawi, Mali, Tanzania and Uganda. The campaign carried out 49 participatory radio campaigns through 25 state, community and religious radio stations across the 5 countries.

Nearly 80 percent of small-scale farmers in Africa have access to radio and farm radio broadcasts have existed in the continent for a long time but most have not inspired large-scale change.

The African Farm Radio Research Initiative wanted to see how radio could be used to reach farmers at a larger scale. Using radio broadcasts that explained available and tested farming improvements, the initiatives focused on what farmers in the target communities said they wanted. Broadcasts were then scheduled at times that were most convenient to the farmers in each region. The programs featured interviews and content from members of participating ‘active communities’ and each week a successful farmer’s experience was featured in the shows. Listeners were asked to decide if they would try the improvement they had heard about and they were given a chance to comment and be heard through live calls and short message service (SMS).

The study compared the reach and impact of 14 participatory radio campaigns in a participating community and a control community which never received the signals. The experiment also assessed the impact of the broadcasts in the larger community that was reached by the broadcasts.

‘The results were compelling,’ says David Mowbray, the manager in charge of training and standards at Farm Radio. ‘We found that 39 percent of the active listeners and 22 percent of the passive listeners had started new practices to improve their farming since the start of the broadcasts,’ he said. Mowbray, who presented the findings of the survey at the International Livestock Research Institute (ILRI) on 17 September 2012, said that as a result of the initiative, nearly 1 million small-scale farm households tried what they heard on radio in the 5 countries.

‘The participatory radio campaign approach worked because radio programs were broadcast in local languages and allowed farmers to learn from each other,’ said Mowbray.

Farm Radio is now carrying out a follow-up survey to investigate how the adoptions spread after the end of the campaign and if the early adopters have continued using the methods they learnt. The organization hopes to scale out the methodology used in this study to other parts of Africa.

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).

Misku’s story: How sheep fattening is transforming lives in western Ethiopia

Posted on October 1, 2012 by Susan MacMillan

This very brief photofilm (1:41 minutes) shares the story of Misku Abafaris, a woman farmer in Ethiopia, who was interviewed in 2010 about the changes in her life as a result of interventions by an ILRI-led Improving Productivity and Market Success of Ethiopian Farmers (IPMS) project. Since 2006, ILRI has been working closely with Ethiopia’s Ministry of Agriculture and Rural Development to improve farmers’ livelihoods.

When asked what life was like a decade ago, Misku Abafaris immediately says: ‘In those days I was never exposed to any new ideas, any new approaches.’ Then, after more consideration, the 40-year old mother of six turns to practical matters. ‘I used to spend most of my time caring for my children and preparing food. And I’d look after our cow and help my husband when the crops needed weeding.’

In short, her daily routine in Gudeta, a small village some 30 minutes’ walk from a tarmac road, was little different from that of earlier generations of women in Ethiopia’s Oromiya Region. There were good years, when the coffee harvest was plentiful, and bad years, when the coffee failed or drought shrivelled their food crops.

Five of Misku’s children still live at home, chickens still wander in and out of their mud-walled, tin-roofed dwelling, and it’s still a long walk to the nearest well to get drinking water. But new ideas and new approaches, so lacking in the past, have recently helped to transform their lives. Their most obvious manifestation can be seen in the fields below the village, where half a dozen handsome sheep are being fattened for the market.

‘With the profits I’ve made from my sheep, I’ve been able to buy a Boran heifer, which will yield much more milk than our local breed of cow’, says Misku, ‘and last year, when we didn’t get a coffee harvest, we still made enough money from the sheep to pay all our household expenses.’ She’s particularly proud of the fact that her sheep-fattening business has paid for her eldest daughter, now 21 years old, to live and study in the nearby town of Agora.

Misku’s forgotten to tell you about the chairs we’re sitting on’, says Abafaris Abamaliky, her husband. ‘It was the money from the sheep that paid for the timber and the carpentry. And it paid for the wooden box where I now keep my clothes and my private things.’ The pride he takes in his wife’s achievement is plain to see.

The power of knowledge
Misku and her husband are among tens of thousands of farmers to benefit from a project which has helped them to improve the productivity of their livestock and crops and—crucially—market their produce more effectively. Funded by the Canadian International Development Agency (CIDA) and managed by the International Livestock Research Institute (ILRI) on behalf of the Ministry of Agriculture and Rural Development, the Improving Productivity and Market Success of Ethiopian Farmers (IPMS) project was launched in 2006.

Goma, where Misku and her family live, is one of 10 districts where the project operates. The early stages involved the identification of crops and livestock which could benefit from activities to improve production and marketing. This followed lengthy consultations with farmers and local government staff. In Goma the focus has been on improving ‘value chains’—linking production, the supply of farm inputs and the markets—for coffee, poultry, honey, fruit and sheep.

‘Many farmers were keen to develop sheep fattening, but they didn’t have the knowledge or skills to improve production’, explains Yisehak Baredo, the project’s research and development officer in Goma. ‘Their sheep were in poor health, and it took them up to a year to fatten them.’ Misku’s experience was typical: she used to keep just one sheep, whose only food supplement was kitchen scraps, and she made hardly any money fattening its lambs.

In 2008, the project provided training on sheep fattening for Misku and 119 other farmers. They learned, among other things, about the importance of providing their animals with protein-rich food supplements and how to keep them in good health. Such was the success of the first training program that the project repeated the exercise for 92 farmers a year later.

None of this would have been possible without access to credit, which was provided through a local microfinance institution. Talk to any of the farmers who benefited and they’ll tell you in great detail precisely how they spent their first loans.

Misku borrowed 1500 birr (USD115). With this she bought five young sheep, a supply of cotton-seed meal, life insurance for herself and insurance for her five sheep, and de-wormers and other veterinary medicines. Three months later, she sold the fattened sheep and paid back the loan, leaving her a net profit of 1200 birr (USD90)—a considerable sum of money in one of the poorest countries in the world. Subsequent fattening cycles have provided her with similar profit margins.

So is her story unusual? Yes and no. Yes, in the sense that she is a strong and respected leader, and the group of 30 smallholders which she chairs was immediately able to repay its loans in full—something several other groups failed to achieve. As a result, the microfinance institution has been happy to provide further loans. And no, in the sense that many other farmers have made a success of fattening their sheep and increasing their income. Over four out of five who received training shortened the fattening period to just three months.

‘With the profits I’ve made from the sheep, we’ve built an extension to our house and bought a high-yielding Boran cow’, says Suchare Abamaliky, one of Misku’s neighbours. Musa Kadir, who belongs to the same peasant association, has used the profits from his sheep to pay school fees for his children. ‘I’m now earning as much money in three months as I used to make in a year from the sale of coffee beans’, he says. He has ambitious plans to expand the number of sheep he fattens, and he’s also begun to raise avocado and mango seedlings, having observed the activities of one of his neighbours. Shito Nasir had received training on how to graft superior varieties of fruit tree. ‘I could see she was making such a good business that I decided to do the same’, explains Musa Kadir. This is the way new ideas are beginning to spread, across hedges and fields from farmer to farmer.

A rural revolution?
Abafaris Abamaliky is some 20 years older than his wife, Misku, and he has lived, as he puts it, through three governments. Life is now better than it ever was in the past, he says. ‘We now have electric light in the village and better health care.’ Just as importantly, he and his neighbours now feel they can talk openly to government officials. Indeed, the success of the IPMS project owes much to the close relationship between villagers and the staff at the district offices of the Ministry of Agriculture and Rural Development.

Besides introducing new technologies to Ethiopian farmers, the project has begun to change the way government staff approach agricultural development. ‘Before the project began, we used to focus on increasing the production of particular commodities, but we knew nothing about value chains’, explains Tanashe Eyasu at the local Office of Agriculture and Rural Development. ‘Now, we’re changing the way we work, and we’re linking producers with suppliers of inputs like fertilizers and feed, and sometimes even linking them with buyers as far away as Addis Ababa.’

Although the IPMS project will come to an end at the end of this year (2012), its impact is assured. ‘You can already see the knowledge being transmitted from farmer to farmer’, says Tsegaye Umeta, Goma’s district administrator, ‘and local government staff will continue to promote the knowledge and practices introduced by IPMS to new areas.’ It shouldn’t be a hard sell: when farmers are making good money, others will follow where they lead. And already, new businesses have sprung up to provide feed, fertilisers, medicines, beehives and other equipment.

If you ask Misku about her hopes for the future, she lists her priorities without hesitation. ‘My first desire is to support my children, so they can go to college’, she says. ‘Then, if God is willing, I would like a better house, with a cement floor, not a mud floor like this one, and with brick walls painted a nice colour. I’d also like a well.’ A while ago, she went on a farmers’ study trip to the capital, where she saw a small pump for drawing well water. ‘I’d like that too’, she says.

But is this a dream too far for a family which has just three hectares of land, a pair of oxen, two cows, ten chickens and a small flock of sheep? ‘No’, she replies. ‘If we continue to work hard, I’m sure this will happen.’ Her husband nods in agreement.

As we leave the village, we are accompanied by a chattering crowd of children, including Misku’s eight-year-old boy. When Ariso is not at school, he helps to look after the family’s sheep, but he also has a lamb of his own, which he recently bought with money he earned picking coffee.

‘Once I have fattened it up’, he says, ‘I will make a good profit.’ He probably hasn’t heard of ‘value chains’, but he is very much his mother’s son: he understands the importance of the market.

Addressing the issue of our time: Experts meet in Nairobi to shape new nutrition program for Africa by new Australian food security centre

Posted on September 19, 2012 by Paul Karaimu

This 10-minute film shares the views of 10 nutrition, food policy and food safety experts who discussed gaps between research on food security, agriculture and nutrition in Africa at a meeting in Nairobi on 10–11 Sept 2012. Interviewed are: Mellissa Wood, Australian International Food Security Centre (AIFSC); Delia Grace, International Livestock Research Institute (ILRI); Bruce Cogill, Bioversity International; John McDermott, CGIAR Research Program on Agriculture for Nutrition and Health (A4NH); Robyn Alders, University of Sydney; Juliet Ssentubwe, Uganda Ministry of Agriculture; CJ Jones, Global Alliance for Improved Nutrition (GAIN); Ruth Oniang’o, member of the policy and advisory council of the Australian Centre for International Agricultural Research (ACIAR); Mateete Bekunda, International Institute for Tropical Agriculture (IITA); and Cyprian Ouma, World Vision.

A new program to help deliver improved nutrition to Africa was recently designed at a workshop in Nairobi on 10–11 September 2012. The expert panel defined research priorities for Australian investments in the sphere of food and nutritional security in sub-Saharan Africa.

The workshop helped advance progress on what Hilary Clinton and others argue is the issue of our time—food security.

More than one billion people remain malnourished, and another billion suffer from hidden hunger due to lack of essential vitamins and minerals in their diets—this while another 1.5 billion people are overweight or obese and are in need of Testosterone booster supplements to help them loose weight.

The workshop helped advance progress on what Hilary Clinton and others argue is the issue of our time—food security.

If you are getting ready to start or get back on your fitness journey after being on hiatus then Maria’s story below is a must read. After seeing her friends’ awesome results, Maria joined the program and has lost 10lbs & 10 inches and found a love of fitness…all with just starting with 2 days per week and combining mi diet with a new cannabis product I found online, the delta 8 thc flower!

Delta-8 is a cannabis compound that has become popular because of its similarity to delta-9 THC, the main compound in cannabis that gets you high, causing euphoria, happiness, sedation, symptom relief, and much more. Large amounts of THC are found in a majority of cannabis strains. What we know from the 2004 study is that mice ate 16% more food over a nine-day period after being given carts with D8. This was more than the D9 group. This suggests that with more research, delta-8 might become a therapeutic tool for those who face food intake challenges for a number of reasons. Additionally, exploring cannabis for fibromyalgia could provide symptom relief for individuals suffering from chronic pain.

A key to achieving lasting food security is meeting the challenge of providing food and adequate daily nutrition to all.

The agricultural sector rarely has ‘enhancing nutrition’ as an articulated objective. Delia Grace, a veterinary epidemiologist and food safety expert at the International Livestock Research Institute (ILRI), in Nairobi, Kenya, says: ‘A consensus is growing that the disconnect between agriculture, health and nutrition is at least partly responsible for the disease burden associated with food and farming’. The Australian International Food Security Centre (AIFSC), a new Australian Government initiative announced in October 2011, and ILRI hosted the 1.5-day workshop to help address this disconnect.

Experts in nutrition, national and subregional food policy, food safety, agricultural production and value chains from across Africa and the world participated.

Participants in the meeting discussed gaps between research on food security, agriculture and nutrition, in line with African priorities and how the Australian International Food Security Centre can best complement work being undertaken by other organizations. The centre will use the outcomes of the workshop to shape its nutrition program by identifying where to make its initial investments in African food security.

The Australian centre aims to help bridge existing gaps between agricultural innovations and development so as to speed adoption of those innovations for better food and nutritional security of poor people.

Mellissa Wood, director of the Australian International Food Security Centre, says Australia has a role to play in this area. ‘Australia has many similar environments and challenges common to African agriculture. Our expertise in agriculture can help play a role in achieving food security in Africa, including developing more nutritious food,’ Wood said.

Australian agricultural science has experience with climatic variability and extreme climatic events that affect farming, forestry, fisheries and livestock. While eventually working in developing countries across Africa, Asia and the Pacific, the Australian International Food Security Centre is focusing its first efforts in sub-Saharan Africa.

The new Australian centre will work specifically to:

increase the nutritional quality, safety and diversity of food
reduce food losses after harvest
improve access by the poor to markets and other business opportunities
build the capacity of local institutions and individuals
promote gender equality

Rinderpest: Scourge of pastoralists defeated, at long last, by pastoralists

Posted on September 18, 2012 by Susan MacMillan

A timeline of major events in the history of rinderpest in Africa from its introduction in 1887, in military cattle brought to Eritrea to feed troops, to the declaration of rinderpest’s eradication in 2011. RP, rinderpest. (Illustration credit: Figure 1 in ‘Rinderpest eradication: Appropriate technology and social innovations’, 2010, by Jeffrey Mariner et al. Science 337, 1309.)

The invention of sex and death, evolutionary biologists tell us, allowed organisms to escape wholesale extermination by parasitic infections. The invention of antibiotics and other miracles of modern medicine allows many of us, particularly in rich countries, to think we can escape most disease, if not death. This of course is over-optimistic and flies in the face of all of human history. Disease has altered those histories, stamped whole continents with its imprint, shaped global affairs—bubonic plague in 14th-century Europe, smallpox in the Americas in the 16th century following European invasion, potato blight in 19th-century Ireland, the Spanish flu pandemic that circled the world in 1918, malaria and HIV/AIDS in Africa today.

Some of the most important diseases have killed human populations indirectly, by annihilating the crops and animals that sustained us. This happened when late blight affected the potato crop in Ireland in the 1840s, killing some 1 million people and causing another 1.5 million to emigrate in The Great Hunger, and when brown spot of rice ruined crops in Bangladesh and eastern India in 1943, leading to the deaths of 2 million or more people in The Bengal Famine.

Among the latter ‘food plagues’ is a remarkably little-known viral disease of cattle and other ungulates that ‘has been blamed for speeding the fall of the Roman Empire, aiding the conquests of Genghis Khan and hindering those of Charlemagne, opening the way for the French and Russian revolutions, and subjugating East Africa to colonization (Rinderpest, scourge of cattle, is vanquished, New York Times, 27 Jun 2011).

Rinderpest, a German term meaning ‘cattle plague’, is a viral disease related to measles (recent evidence suggests the measles virus may have diverged from the rinderpest virus during the Middle Ages). It is arguably the most important animal disease historically. It entered the Horn of Africa from the port of Massawa, in what is now Eritrea, in 1887 with an invading Italian army that was importing Indian cattle for food and draft power.

The virus exploded so fast that it reached South Africa within a decade (and is considered one of the factors that impoverished Boer farmers as war with the English approached). It doomed East Africa’s wandering herders, subsisting on milk mixed with cow blood. Historians believe a third of them or more starved to death—Rinderpest, scourge of cattle, is vanquished, New York Times, 27 Jun 2011.

Killing animals within days of infection, the rinderpest epidemic emptied East Africa of most of its large grazing animal populations, wiping out 80–90 per cent of the region’s cattle, which, it is argued, left the remaining population too weak from hunger to oppose European colonialism.

Rinderpest struck East Africa in 1890, and in two years 95 percent of the buffalo and wildebeest there had died. So began a series of events of such profound ecological importance that the repercussions are still being felt today.—A R E Sinclair and M Norton-Griffiths, editors, Serengeti: Dynamics of an Ecosystem, 1979.

Journalist Fred Pearce gives more details.

Great pastoral civilizations across the continent were shattered. Central African cattle-rearing tribes like the Tutsi and Karamajong starved, along with Sudanese nations like the Dinka and Bari, West Africans like the Fulani, and southern Africans like the Nama and Herero. The folklore of the Maasai of East Africa tells of the enkidaaroto, the “destruction,” of 1891. They lost most of their cattle, and two-thirds of the Maasai died. One elder later recalled that the corpses were “so many and so close together that the vultures had forgotten how to fly.”

Many of these societies never recovered their numbers, let alone their wealth and power. Rinderpest served up the continent on a plate for European colonialists. In its wake, the Germans and British secured control of Tanzania and Kenya with barely a fight. In southern Africa, the hungry and destitute Zulus migrated to the gold mines of Witwatersrand, helping to create the brutal social divide between black and white from which apartheid sprang.

It is an extraordinary story, rarely told. . . .

Fred Pearce: Why Africa’s national parks are failing to save wildlife, Yale Environment 360, 19 Jan 2010.

Dan Charles, of National Public Radio, in the USA, reports on an article published in Science this month demonstrating that it was African cattle herders that wiped this ancient plague from the face of the Earth.

‘Twice in all of history, humans have managed to eradicate a devastating disease. You’ve heard of the first one, I suspect: smallpox. But rinderpest? . . .

‘In this week’s issue of the journal Science, several of the architects of rinderpest’s elimination lay out the reasons for their success. The key innovation wasn’t technological, they say. It was social and cultural.

‘Technology certainly played a part. Half a century ago, a British veterinarian named Walter Plowright, working in Kenya, created the first truly effective and safe vaccine for rinderpest. . . .

‘Later, Jeffrey Mariner of the Tufts Cummings School of Veterinary Medicine, developed a version of the vaccine that didn’t need to be refrigerated, allowing veterinarians to use it far from roads and electricity.

‘Yet the disease persisted in Africa, surviving in remote areas plagued by weak government and chronic conflict, such as southern Sudan and parts of Uganda, Ethiopia, and Somalia. Veterinarians rarely ventured into those areas, and it was hard to know where vaccinations were even needed because government officials were reluctant to report outbreaks.

Mariner, who now works at the International Livestock Research Institute in Kenya, says that ultimately, the skills and knowledge of nomadic cattle herders who lived in those hard-to-reach areas were the keys to cracking the rinderpest puzzle.

“Those farmers could tell us where outbreaks were occurring,” Mariner tells The Salt, speaking by phone from Nairobi. In addition, some nomadic farmers got training as “community animal health workers” and were able to carry out vaccinations themselves. They proved better at the job than veterinarians, in part because they knew their animals. . . .

Tom Olaka, a community animal health worker in Karamajong, northern Uganda, was part of a vaccination campaign in remote areas of the Horn of Africa that drove the cattle plague rinderpest to extinction in 2010 (photo credit Christine Jost).

‘Tom Olaka, a community animal health worker in the border region between Uganda, Sudan, and Kenya, identified and reported the last outbreak of rinderpest in 2000. The virus was officially declared extinct last year. Around the world, cattle farmers can breathe just a little easier.’

New analysis in ‘Science’ tells how world eradicated deadliest cattle plague from the face of the Earth

Posted on September 13, 2012 by Susan MacMillan

In a new analysis in Science, ILRI researcher Jeffrey Mariner describes how the world eradicated deadliest cattle plague, the second such success after smallpox. The authors of the paper reveal the essential role of Africa’s nomadic herders in ridding the world of rinderpest.

A new analysis published today in Science traces the recent global eradication of the deadliest of cattle diseases, crediting not only the development of a new, heat-resistant vaccine, but also the insight of local African herders, who guided scientists in deciding which animals to immunize and when. The study provides new insights into how the successful battle against rinderpest in Africa, the last stronghold of the disease, might be applied to similar diseases that today ravage the livestock populations on which the livelihoods of one billion of the world’s poor depend.

Capable of wiping out a family’s cattle in just a few days, rinderpest was declared vanquished in May 2011. After smallpox, it is only the second disease (and first livestock disease) ever to be eradicated from the earth.

‘The elimination of rinderpest is an enormous triumph against a disease that has plagued animals and humankind for centuries’, said Jimmy Smith, director general of the International Livestock Research Institute (ILRI). ‘Science succeeded despite limited resources, and we now know how. We are committed to applying the lessons in this study to making progress against other similarly destructive livestock diseases.’

According to the analysis, which was conducted by international scientists coordinated by ILRI, and published this week in Science, the eradication of rinderpest happened thanks to the development of an effective temperature-stable vaccine, collaborations between veterinary health officials and cattle farmers to deliver those vaccines, and reliance on the knowledge and expertise of the local herders to determine the location and movement of outbreaks.

The cattle plague and its path of destruction
Rinderpest, known as ‘cattle plague’ in English, is thought to have had its origin in the dense cattle herds of Central Eurasia more than two millennia ago and subsequently spread through warfare and trade to cattle in Europe, Asia and eventually Africa. Caused by a virus related to the one that causes measles and canine distemper, rinderpest could infect cows, water buffalos and other cloven-hoofed animals, leading to a high fever, severe diarrhea, then dehydration and emaciation. The pathogen could kill 90 per cent of a herd, wiping out an entire farm’s livestock in just a matter of days. There was no treatment.

While rinderpest is not dangerous to human health, its impact on humanity has been significant. Its path of destruction has been linked to many history-changing events such as the fall of the Roman Empire, the French Revolution and famines throughout Africa since the 19th century. Indeed, 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 affect a family’s economic health, while depriving it of a primary source of nutrition.

Road to eradication
The first major contributing factor to eradication, as identified by the analysis, was a major improvement made to an existing rinderpest vaccine. While the original vaccine was safe, effective, affordable, and easy to produce, it needed to be refrigerated—making it nearly impossible to transport it to remote rural villages. With the development of a new heat-resistant vaccine formulation in 1990 that could be stored at 37 °C for eight months, and in the field without refrigeration for 30 days, scientists had a tool that would become the cornerstone of the eradication effort in remote pastoral areas of Africa.

But according to ILRI’s Jeffrey Mariner, the analysis’ lead author and inventor of the temperature-stable rinderpest vaccine, it was the role played by pastoralists that really turned rinderpest on its head.

As part of a public-private-community partnership, Mariner and colleagues trained what they called community-based animal health workers, or CAHWs—local pastoralists who were willing to travel on foot and able to work in remote areas—on how to deliver the new vaccine. These CAHWs carried the vaccine from herd to herd, immunizing all the cattle in their communities.

The local herders performed as well, if not better, than did veterinarians at vaccinating the herds—in fact often achieving higher than 80 per cent herd immunity in a short time—remarkable for a disease that had plagued most of the world for millennia. Indeed, it turned out that the pastoralists were not only very, very good at delivering the vaccine, but that they also knew more about the disease and how to stop it than many of the experts.

‘We soon discovered that the livestock owners knew more than anyone—including government officials, researchers or veterinarians—where outbreaks were occurring’, Mariner said. ‘It was their expertise about the sizes of cattle herds, their location, seasonal movement patterns and optimal time for vaccination that made it possible for us to eradicate rinderpest.’

Based on their immense expertise about migratory patterns and in recognizing early signs of infection, the herders were able to pinpoint, well before scientists ever could, where some of the final outbreaks were occurring—often where conventional surveillance activities had failed to disclose disease. Harnessing this knowledge of rinderpest through ‘participatory surveillance’ of outbreaks to CAHW delivery of vaccination proved to be the most successful approach to monitoring and controlling the disease. It effectively removed the disease from some of the hardest-to-reach, but also most disease-ridden, communities.

Applying rinderpest lessons to other diseases
While livestock and those who depend on them for food, transportation and economic stability are now safe from one major pathogen, they continue to be plagued by a number of other dangerous and debilitating diseases—some as deadly as rinderpest.

The international animal health community is now gearing up to address the next major constraint to livestock livelihoods in Africa and Asia. In their analysis, Mariner and colleagues consider how the lessons learned from battling rinderpest can be applied to protect livestock from other infectious agents—particularly peste des petits ruminants (PPR), also known as ‘goat plague’. Strategies to address PPR using the lessons from rinderpest have been developed and action is under way to mobilize international support for a coordinated program to tackle PPR. As a next step, ILRI and the Africa Union/Interafrican Bureau for Animal Resources are planning to host the next meeting of the PPR Alliance, a partnership of research and development organizations who prioritize PPR, in Nairobi in early 2013.

A dangerous virus that can destroy whole flocks of sheep and goats, PPR threatens livestock owners in Africa, Asia and the Middle East, in particular. As with rinderpest, a sheep or goat infected with PPR will come down with a high fever and will stop eating, leading to severe diarrhea and death. Eventually, it will take down the entire herd of the animals, which are equal to cattle in their importance to the poor. And controlling PPR is made challenging by the short life span and heavy trading of sheep and goats—making it difficult to keep the disease in check and preventing its spread to new areas.

Nonetheless, the lessons of rinderpest eradication have begun to have an impact on the toll exacted by goat plague. Participatory surveillance methods are now applied in many countries, CAHWs are now frequently involved in vaccination campaigns and ILRI has developed a temperature-stable vaccine that can be transported to rural farms and has started to put into place training programs for shepherds and farmers in Uganda and Sudan to deliver it.

Eventually, these same lessons could be applied to other livestock diseases such as foot-and-mouth disease—even some that have recently jumped to humans, like avian flu. Such ‘zoonotic’ diseases are responsible for 2.4 billion cases of human illness and 2.2 million deaths per year, primarily in low- and middle-income countries.

Kenya’s minister of state for development of northern Kenya and other arid lands, Mohamed Elmi, has praised a livestock insurance project implemented in Kenya by the International Livestock Research Institute (ILRI) and other partners for its role in improving the productivity of the country’s drought-prone arid and semi-arid lands. If you also need to handle a delicate business plan. we recommend reading here about this project management software Australia business are using.

‘The index-based livestock insurance project in Marsabit District is an excellent example not just of innovative risk management, but of how, with thought and imagination, basic services such as insurance can be brought within reach of those previously excluded,’ said Elmi.

The minister was speaking last week (7 Sep 2012) at the launch of a five-year Kenya Rural Development Programme at the Kenya Agricultural Research Institute rangeland research station at Kiboko, located in Makueni County. Representatives from the Kenya government, the European Union and international research organizations, including ILRI, participated in the launch.

The Kenya Rural Development Programme is a new five-year agricultural support program funded by the European Union at 66 million euros. It is seeking to improve drought response and management and agricultural productivity in the country’s arid lands and to reduce the vulnerability of people living in these areas.

Jimmy Smith, the director general of ILRI, who attended the launch, said the index-based livestock insurance project is making rangelands-based livelihoods more sustainable.

‘Promoting food security and reducing poverty in arid areas is a key priority for the government. I’m delighted the minister highlighted the role IBLI is playing in this process; ILRI is committed to making an important contribution,’ said Smith.

The insurance project, which was piloted in Marsabit District, in northern Kenya, in 2010, is a component of the Kenya Rural Development Programme. The project is a result of collaborative efforts between ILRI, UAP Insurance, Cornell University and the Index Insurance Innovation Initiative, based at the University of California at Davis. A second phase of the project, which started in southern Ethiopia in August 2012, has received 1 million euros from the European Union.

‘The Kenya Rural Development Programme responds to the development needs of the rural people in Kenya and the support given by the European Union to the agricultural sector will improve the lives of people in the country,’ said Marjaana Sall, deputy head of delegation of the European Union to Kenya.

The event featured displays of European Union-funded activities in Kenya’s rangelands from the Kenya Rural Development Programme, the Kenya Agricultural Research Institute and ILRI, among other exhibitors, and was attended by local community members and farmers in Kiboko.

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’).
