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

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. . . .

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 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. Above, an Afar community animal health worker in 1993 describes the appearance and characteristics of rinderpest in cattle (photo by Jeff Mariner).

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.

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.

The road back to Rio: Turning straw into gold — Crop ‘wastes’ at the heart of greener livestock development

Posted on June 18, 2012 by Susan MacMillan

Key findings were presented today on ways to enhance the value of coarse crop ‘wastes’—better termed ‘residues’—as feed for cattle, water buffalo, sheep, goats and other ruminant farm animals. The talk was given at a ‘learning event’ that is part of Agriculture Day at the Rio-20 United Nations Conference on Sustainable Development.

Carlos Seré, former director general of the International Livestock Research Institute (ILRI) now serving as chief strategist for the International Fund for Agricultural Development (IFAD), delivered this presentation on behalf of Michael Blümmel, an animal nutritionist based in ILRI’s office in Hyderabad, India, who could not make the event as scheduled.

The gist of the presentation is that wheat and rice straw, maize stover, groundnut haulms and other residues of crops that remain after their grain or pods have been harvested for human consumption are major feed resources for livestock in developing countries. Widespread and increasing shortages of arable land and water in these countries are increasing the importance of these crop residues for livestock feed, and their importance will only increase over the coming decades as human population grows and as more and more people move out of poverty and begin adding more milk and meat to their diets.

In recent years, livestock and crop improvement researchers have worked together to improve the fodder value, in terms of both quantity and quality, of crop residues at their source. They’ve done this in crop improvement programs that incorporate fodder traits in crop selection, breeding and new cultivar release criteria. Key cereals and legumes are tackled and both conventional and molecular breeding techniques are employed. Fodder traders and feed processors have started employing additional interventions to further improve the superior crop straws and stover.

The following examples illustrate the many promising findings from this collaborative fodder research.

01 Nutritionally significant variations exist in crop residue fodder value among existing cultivars that can be exploited through simple phenotyping without detriment to primary crop traits such as grain and pod yields.
As a ballpark figure, 5 percentage units in digestibility can be exploited in crop residue fodder quality without detriment to gain or pod yield in all key cereal and leguminous crops. The advantage of daily milk yield accruing from 5% difference in digestibility of basal diet in well designed ration is about 5 kg per day due to a multiplicator effect from both higher energy concentration in the diet and higher intake.

02 Simple and network-sharable food/feed/fodder nutritional phenotyping techniques have been established, such as near-infrared spectroscopy (NIRS) platforms that support whole-plant crop improvement paradigms and programs.
ILRI NIRS platforms in India and Ethiopia are being used by other research programs (e.g., the new CGIAR Research Program on Livestock and Fish) and research organizations (e.g., the International Center from Tropical Agriculture and the International Centre for Agricultural Research in the Dry Areas). Staff of national agricultural research institutions from the Congo, Eritrea, Ethiopia, Rwanda, Tanzania and Uganda have been trained in the NIRS technology and have access to network-shared NIRS equations. NIRS is increasingly being used to test for more qualitative grain traits such as lysine, tryptophan, iron, zinc and polyunsaturated fatty acids, with the aim of optimizing whole plants. This collaborative research is facilitating the analysis of 50 to 100 cultivars every day and gaining information about all their pertinent grain and crop residue traits.

03 Fodder value can be further increased through conventional crop breeding (such as recurrent selection) and molecular crop breeding (such as quantitative trait loci [QTL] identification and backcrossing).
Identification of stay-green QTLs and their backcrossing into elite sorghum varieties could increase stover digestibility by 3 to 5 percentage units while also increasing the sorghum plant’s drought resistance and water-use efficiencies.

04 In mixed crop-and-livestock agricultural production systems, the rates of adoption of new crop cultivars improved for both food and feed/fodder traits appear to be better than that for adoption of new cultivars improved for food traits only.
In a recent maize project in East Africa, farmers ranked stover traits 2.4 and grain yield 2.9 on a scale of 3. Farmers were most likely to adopt new maize cultivars that had improved stover as well as grain traits. Anecdotal evidence from groundnut adoption studies in India suggests that farmers prefer relatively small additive advantages—say 10% more pod + 10% more haulm + 10% more haulm quality—over (often theoretical) drastic increases in pod yield.

05 Participants in fodder value chains for straw and stover profit from superior straw and stover.
Price premiums for 3 to 5 percentage units in digestibility are in the range of 10 to 30%. There is higher demand for higher quality crop residues and superior sorghum stover is now regularly transported more than 400 km in parts of India. There are significant employment opportunities in harvesting, chopping, transporting and selling these crop residues.

06 Further improvement of superior straw and stover, in the form of supplementation, fortification or densification, can be done in feed processing, with productivity levels achieved from such processed but largely by-product-based feeds being four or more times greater than current levels of production.
Complete rations based on more than on 80% by-products (50–60% straws and stovers) can support 15–16 kg of milk daily in dairy buffaloes, about 1 kg live-weight gain in cattle and 120–130 g in sheep. Complete rations are suitable for smallholder farmers because the rations need not entail complex feed processing options; simply chopping and supplementing residues can suffice.

07 Increasing current yields of animals in India, such as by doubling the average daily yield of 3.6 kg of milk (across buffalo, crossbred and local cattle herds), would reduce levels of greenhouse gases dramatically, decreasing methane emission from dairy production by more than 1 million tons per year.
This is straightforward; increasing average daily milk yields in India from 3.6 to 6 to 7 kg per animal per day would reduce methane production from dairy animals relative to the same amount of milk produced by about 1 million tons per year.

In addition, there are good prospects for mainstreaming such multi-dimensional crop improvement outputs. For example, new CGIAR Research Programs (such as those on maize, rice, dryland cereals, and grain legumes) have already adopted the approach and have incorporated fodder value as high-priority traits in these crops.

Africa’s vast eastern and southern drylands get new attention–and support–from agricultural researchers

Posted on June 6, 2012 by Susan MacMillan

A new CGIAR Research Program on Dryland Systems is being planned to find ways to help dryland communities climb out of poverty while enhancing their food security and protecting their natural resources. This program will conduct four strategic research themes in five regions. Two of the research themes—reducing vulnerability/managing risk and sustainably intensifying production—make up the ‘meat’ of what has come to be called ‘the hamburger’ diagram. The top and bottom ‘buns’ represent the other two research themes: strengthening innovations systems and measuring impacts/synthesizing knowledge across regions, respectively (figure by the CGIAR Research Program on Dryland Systems).

This week in Nairobi, Kenya, opening on a morning as grey and cold as London’s weekend Diamond Jubilee celebrations on the Thames, a Regional Inception Workshop of the CGIAR Research Program on Dryland Agricultural Systems for East and Southern Africa is being held. The 3-day workshop (5–7 Jun) is organized and hosted by the International Livestock Research Institute (ILRI). This inception workshop brings together more than 50 experts working in the drylands of eastern and southern Africa to identify key hypotheses and research questions for the research program, to agree on initial sites for its activities and to develop impact pathways and implementation plans. See the introductory slide presentation by Maarten Van Ginkel, deputy director general of the International Centre for Agricultural Research in the Dry Areas (ICARDA): The CGIAR Research Program on Dryland Systems: Scientific content and progress in the inception phase.

The planners of this CGIAR Research Program on Dryland Systems (the full mouthful of a title of which is ‘Integrated and Sustainable Agricultural Production Systems for Improved Food Security and Livelihoods in Dry Areas’) say this large, multi-institutional, multi-stakeholder and multi-diciplinary research program aims to develop a series of complementary technologies, policies and institutional innovations that will help very poor and highly vulnerable dryland populations improve their livelihoods—and do so over the longer term.

As its full name suggests, this CGIAR research program will apply ‘integrated systems’ approaches, which focus less on technical fixes for discrete problems and more on how interventions can be combined to meet the many needs of a profitable, equitable and sustainable agricultural production system. And the program will use large, so-called ‘landscape level’ frameworks to help scientists think through the links between farm or community practices and the broader ecosystem in which they are located; such analyses should allow, for example, more comprehensive assessments of the increasingly hard trade-offs in use of natural resources.

See consultant John Lynam’s slide presentation (below), which gives a comprehensive overview of ‘systems thinking’. Lynam argued that we need to change our research designs and methods if we’re going to serve the expanding agendas for international agricultural research. In his presentation he asked asked some provocative questions, such as, ‘How do we (should we) understand system performance? Is it by productivity, profitability, or income? Is it levels of vulnerability or food security? Or is it resource efficiency or resilience?. . . . Why do we have plantain (matoke) systems in Uganda while beer banana systems dominate in Burundi and Rwanda? . . . Why are many more people exiting agriculture in Africa than they are in Asia?’

Applying a systems framework to research on African farming systems

Presentation by John Lynam,

The dry areas of the developing world occupy some 3 billion hectares, which represent 41% of the earth’s land area. These drylands are home to 2.5 billion people, who make up about a third of the population in developing countries. At least 16% of this population lives in chronic poverty.

These people make a living from the drylands by growing and managing a mix of food, fodder and fibre crops; vegetables; rangeland and pasture grasses, shrubs and trees; fruit and fuel-wood trees; medicinal plants; livestock; and fish. These dryland people face enormous environmental challenges, which in many regions are likely only to worsen with climate change.

This program targets two kinds of drylands. The first are those with the deepest endemic poverty and the most marginalized and vulnerable people, the most extreme environmental variability, and often the greatest natural resource degradation as well. The second are those with the greatest potential to increase food security and reduce poverty over the short to medium terms.

The future of dryland farming communities, the research planners assume, depends largely on their ability to more effectively manage risk as well as to diversify and intensify their agricultural production systems. The integrated approach the program will take should help people better manage their natural resources and improve their crop, vegetable, livestock, tree and fish production. The approach should also help facilitate for dryland communities the establishment of enabling policy environments; the provision of greater institutional support; and a more equitable distribution of, and control over, resources, access to information, livelihood opportunities and decision-making.

More specifically, this dryland research program aims to:

prioritize agricultural systems for impact
identify key researchable issues
increase the efficiency and sustainability of natural resource use
develop more resilient agricultural systems to manage risk and production variability
promote in situ and ex situ conservation and sustainable use of dryland agrobiodiversity
improve the productivity and profitability of dryland agricultural systems through sustainable intensification, diversification, and creation of value-added products and market links
identify niches of importance to the most vulnerable livelihoods (even if they appear to have low marketing potential)
address constraints faced by the most marginal farmers
develop new partnerships and models of working together.

The structure and process of this workshop, which is focused on eastern and southern Africa, have been developed by an interdisciplinary research team headed by ILRI’s Polly Ericksen, with participants from the World Agroforestry Centre, the International Water Management Institute and the International Crops Research Institute for the Semi-Arid Tropics, as well as agricultural research consultants John Lynam and Brian Keating. The lead centre for this CGIAR research program is the International Center for Agricultural Research in Dry Areas.

In this region, the drylands program plans to work to reduce vulnerability in three areas of three East Africa countries:
Northern Kenya/southeastern Ethiopia: the triangle from Garissa in Kenya to Borana in south-central Ethiopia to Somali Region in southeast Ethiopia
Central Kenya: Baringo District
Southern Kenya/northern Tanzania: Kajiado and Narok districts and Serengeti National Park and Monduli and Samanjiro districts.

The program plans work to intensify agricultural production in three areas of three eastern and southern African countries:
Zambia-Malawi-Mozambique: the Chinyanja Triangle
Northeast Tanzania: from Kahama through Shinyanga to Babati districts
Ethiopia: the Oromia zones of East Shoa, West Shoa, Horogudru and the Amhara zone of North Shoa

Developing a new strategy for ILRI – Your ideas needed

Posted on May 11, 2012 by ILRIComms

Dear Colleague

I am contacting you to request your assistance in developing a new strategy for the International Livestock Research Institute (ILRI).

Our 2002 strategy (‘livestock – a pathway out of poverty’) was based on a simple conceptual framework for understanding the potential roles of livestock in poverty reduction and the contributions of research to these. It described three main opportunities to enhance the role of livestock in providing a pathway out of poverty, summarized as ‘securing critical assets to the livelihoods of the poor’, ‘sustainably improving their livestock productivity for food and income’, and ‘linking livestock keepers to markets’ to increase the value from their production.

Ten years on, we face a rapidly changing world. The context for livestock development is rapidly evolving, driven by the continued Livestock Revolution and a greater recognition that ongoing transformation in the sector in developing countries needs to be adjusted to the diverse situations and aspirations of smallholders and the different livestock commodities they produce. More generally, the food price crisis and heightened volatility has raised concerns about future food security. The private sector in developing country food economies is creating new opportunities for smallholder livestock production and marketing systems, but it is also causing rapid structural changes in scales and quality of livestock commodity production, marketing and consumption. Pressure to raise animal production is increasingly weighed against its impact on the environment, health issues and climate change.

Our analysis suggests that the combined challenges of growing demand for food, continued rural poverty, climate change and scarcity of land, energy and water require changes in livestock production systems, i.e. livestock production needs to be highly productive and highly sustainable. Further, we need to redefine the targets of our research and the ways we best deliver results together with our partners.

We need your help!

As part of our strategy development efforts, we have worked up a short ‘storyline’ that captures some key strategic directions for our future work. We want to ‘ground-truth’ this assessment with other people involved in livestock research and development.

Visit http://ilristrategy.wordpress.com to read this storyline and give us your answers to a few questions.

We have also identified a few ‘tough issues’ where we need some more specific feedback. If you have specific ideas on these we need them:

I very much hope you can take a little of your time to help us better tackle urgent livestock development challenges in the coming years.

Yours sincerely

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.’

About the Handbook
The Handbook provides a comprehensive statement and reference point for hazard and disaster research, policy making, and practice in an international and multi-disciplinary context. It offers critical reviews and appraisals of current state of the art and future development of conceptual, theoretical and practical approaches as well as empirical knowledge and available tools. Organized into five inter-related sections, this Handbook contains sixty-five contributions from leading scholars. 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

Posted on May 1, 2012 by Paul Karaimu

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

Posted on April 29, 2012 by Susan MacMillan

Causes of livestock deaths, figure reproduced in ILRI-AGRA book: Towards priority actions for market development for African farmers: Proceedings of an international conference, Nairobi, Kenya,13-15 May 2009. Nairobi (Source of figure: J McPeak, PI Little and C Doss. 2010. Livelihoods in a Risky Environment: Development and Change among East African Pastoralists, Routledge Press, London.)

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.

Why livestock: The big picture

Posted on April 24, 2012 by Susan MacMillan

Cover of ILRI’s Corporate Report for 2010-11 (cover picture credit: ILRI/Stevie Mann).

Positioned as we are now, squarely between a scientific ‘Planet Under Pressure’ conference held in London in March and a ‘Rio+20 Sustainable Development’ conference in Brazil this June, it seems an appropriate time to raise a topic that rarely gets raised at these large affairs, that is, why livestock matter so much to so many, why they will remain important in pro-poor development for years to come, and what we can do to make smallholder livestock development more profitable, healthy and sustainable.

The 2010–2011 corporate report of the International Livestock Research Institute (ILRI) provides a ‘big-picture’ overview of these topics.

If you haven’t seen it, we invite you to take look. As the foreword points out:

Whether your main interest is increasing food production, or sustaining farming systems, increasing the incomes of the poor, developing new global bread baskets, making better use of dryland resources, conserving biodiversity, slowing climate change, helping people cope with climate change, or enhancing human health and nutrition, you will find livestock issues critical to your concerns.

‘. . . In the developing world, livestock are the fastest- growing part of agriculture. They’re a ‘demand-pull’ that can drive small-scale agricultural systems—the motor that brings in cash to smallholder mixed crop- and-livestock farmers. While cereals sustain the family, farm animals are the family’s source of cash— its living ‘asset base’.

‘Due to population growth and other drivers of change, many of the developing world’s livestock systems are transforming as fast as they are growing. Science needs to help the world’s poorer livestock keepers make better and more sustainable use of the big changes and new trends. That’s where, and why, the role of livestock science is so critical. . . .’

A short introduction—’Livestock matter(s): The big picture gets bigger—and the following six two-page chapters tell (some of) the story.

Livestock sustain smallholder food production:

Smallholder livestock farming is a mainstay of the poor

Livestock products feed incomes as well as people:

Livestock value chains are valuable value chains

Livestock intensify mixed farm production:

Small-scale crop-livestock farmers will feed the growing world

Livestock make productive use of dryland resources:

Smart livestock-related support reduces pastoral vulnerability

Livestock influence climate change—for good and bad:

Smallholders can make their livestock production much more efficient and profitable

Livestock impact human health—for better and worse:

Animal matters are life and death matters for human health and nutrition

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.

A new global alliance for a safer, fairer and more sustainable livestock sector

Posted on April 13, 2012 by Susan MacMillan

Eight major organizations working in livestock development are issuing a joint communiqué today, committing themselves to working in closer alliance to develop and fulfill on a global agenda for the livestock sector that is safer, fairer and more sustainable. The organizations are:

African Union-Interafrican Bureau for Animal Resources
Association of Southeast Asian Nations
Bill & Melinda Gates Foundation
Food and Agriculture Organization of the United Nations
International Fund for Agricultural Development
International Livestock Research Institute
World Bank
World Organisation for Animal Health

This communiqué was developed by participants of a High-Level Consultation for a Global Livestock Agenda to 2020, co-hosted by the World Bank and the International Livestock Research Institute (ILRI) in Nairobi, Kenya, 12–13 Mar 2012. At that meeting, leaders in livestock development issues exchanged ideas, concerns, experiences and expertise with the aim of developing closer partnerships, a shared vision and more complementary programs for a global livestock agenda. They agreed on the outlines of a consensus regarding strategies for a safer, fairer and more sustainable global livestock agenda to 2020. The full joint communiqué follows.

A new global alliance for a safer, fairer and more sustainable livestock sector
In the face of a fast-growing, resource-hungry and commonly misunderstood livestock sector, it is clear that increased investment in the sector is essential to livelihoods, global health and the environment. To address livestock as a global public good, a strengthened alliance has been formed among key institutions charged with shaping and steering the global livestock agenda.

We, the representatives of global and regional institutions whose mandates cover livestock, met in Nairobi, Kenya, 12-13 March 2012. We exchanged ideas, concerns, experiences and expertise with the aim of developing closer partnerships, a shared vision and more complementary programs for a global livestock agenda.

Our consultation came at an opportune time. Global production and consumption of meat, milk and eggs are growing fast, especially in developing countries, in the face of diminishing natural resources. Decision-makers and investors continue to under-appreciate the critical role that livestock play in the lives and livelihoods of the world’s poorest people. The world remains alert to the risk of pandemics arising at the interface between people and animals.

We agreed that social equity, global health and the environment should be considered among the strategic ‘pillars’ of the global livestock agenda. There was also much concurrence on the issues and challenges facing the livestock sector and the ways to address them.

We are building this alliance to work in closer partnerships, with each organization bringing to bear its comparative advantage. Together we aim to be more effective in explaining to the world better why livestock are essential to the society and to the health and wellbeing of the poor and to show leadership in addressing the challenges and opportunities that livestock can bring.

We will do this by marshalling the best evidence to support our case; directly addressing the harm as well as benefits generated by livestock; learning from successes and failures to design and implement the most appropriate programs and policies; exploiting advances in our understanding of complex systems and powerful new technologies; and building on existing successful initiatives. We aim to develop strategic goals, and to create, and share publicly, a means to measure progress against these goals.

We invite our colleagues in other institutions, public and private, to join us.
