Edinburgh-Wellcome-ILRI project addresses neglected zoonotic diseases in western Kenya

Posted on July 28, 2010 by Paul Karaimu

‘Neglected diseases are diseases of neglected peoples’—Eric Fèvre

Animals and people live close together throughout the developing world. Chickens, goats, pigs, cows and other farmed animals range freely in and out of rural homesteads as families go about their daily lives. This space-sharing by people and their livestock makes good use of the small plots of land managed by the world’s many smallholder farmers; food that might otherwise go to waste can be fed to the animals, for example, while animal manure feeds the cropland by fertilizing it. Most of the world’s smallholder farmers depend on their animals for milk, meat and eggs to feed their families, with the surplus generating much-needed regular household income.

However, such close proximity to their animals puts many people at risk of ‘zoonotic’ diseases, which are those transmitted between people and animals. Remarkably, more than 60% of all human diseases are infections they can get from animals and more than 70% of today’s emerging diseases, such as bird flu, are zoonotic.

Because human and animal health are particularly intertwined in poor countries where people and livestock live in such close proximity, efforts to improve human health in the developing world need to focus on improving animal as well as human health. This makes it necessary for medical and veterinary experts to collaborate and for livestock farmers and herders to be made aware of the disease risks their animals pose to the health of their households.

A project begun in 2009 and funded by the Wellcome Trust, with other support from the International Livestock Research Institute (ILRI), is studying neglected zoonotic diseases and their epidemiology to raise levels of health in poor rural communities. The project, People, Animals and Their Zoonoses, is based in Kenya’s Busia District, which sits on the country’s western border, with Uganda.

Eric Fèvre, who is working jointly for the International Livestock Research Institute (ILRI) and the University of Edinburgh, is the project’s principal investigator and leader. Fèvre says this study is important.

‘Zoonotic diseases are a great burden on poor communities’, Fèvre says. ‘In a poor household where animals and people are in regular close contact, there is a significant chance of zoonotic diseases spreading. Typically in such areas, animals have access to human waste, there is little preventative health services for livestock and there is poor-quality food and forage for people and animals.’

With insufficient and/or unreliable health infrastructure and with many poor people not readily seeking professional medical attention, these diseases often go underreported or misdiagnosed. Complicating and aggravating this already serious health situation, he says, is that ‘in some cases, other non-zoonotic infections may already be present.’

Furthermore, as reported in the May 2010 issue of Veterinary Record, Fèvre says:

‘While malaria is undoubtedly a very serious health issue, its overdiagnosis hides many other problems. To compound this, people in marginalised communities can easily fall off the policy radar – many may be born, live and die without official record being made of them and, as such, they have a weak, or nonexistent, political voice. Thus, while the diseases are grouped as “neglected zoonotic diseases,” it would be equally correct to identify them as “diseases of neglected populations”.’

The Kenya zoonotic study is a four-year project that brings together ILRI scientists in Kenya with researchers from the School of Biological Sciences at the University of Edinburgh and from the Kenya Medical Research Institute, the latter of whom are already working in much of Kenya’s Western and Nyanza provinces. These epidemiologists, veterinarians, medical health professionals and laboratory technologists will visit over 500 homesteads in Busia to collect data and samples from people and livestock; those people found ill will be treated or referred to specialists.

The project data will be used to quantify the place of zoonoses in the context of other infectious diseases and to refine our understanding of factors that put people and livestock at risk. The study team also aims to come up with diagnostic tests that can be used in the field and to design cheap, easy-to-implement health interventions for both people and livestock. The project is focusing on bovine tuberculosis, cysticercosis, brucellosis, Q-fever, Rift Valley fever and trypanosomiasis (in cattle) /sleeping sickness (in people) and their impacts on both livestock and the people.

The results of this project are expected not only to improve the health aspects of the relationship between people and their livestock in western Kenya but also to provide important background for future research and policymaking on zoonotic issues.

Les experts avertissent que la disparition rapide du bétail indigène de l’Afrique menace l’approvisionnement alimentaire du continent

Posted on July 22, 2010 by Susan MacMillan

D’ « anciennes » espèces bovines d’Afrique de l’Ouest, résistantes aux maladies, figurent parmi les races qui risquent de disparaître parce que le bétail importé est en train de supplanter un précieux cheptel indigène.

Une action urgente est indispensable pour arrêter la perte rapide et alarmante de la diversité génétique du bétail africain qui apporte nourriture et revenus à 70 % des Africains ruraux et constitue un véritable trésor d’animaux résistants à la sécheresse et aux maladies. C’est ce que dit une analyse présentée aujourd’hui à une importante réunion de scientifiques africains et d’experts du développement.

Les experts de l’Institut international de recherche sur l’élevage (ILRI) ont expliqué aux chercheurs réunis pour la cinquième Semaine africaine des sciences agricoles (www.faraweek.org), accueillie par le Forum pour la recherche agricole en Afrique (FARA), que des investissements sont indispensables aujourd’hui même pour intensifier, en particulier en Afrique de l’Ouest, les efforts d’identification et de préservation des caractères uniques de la riche variété de bétail bovin, ovin, caprin, et porcin, qui s’est développée au long de plusieurs millénaires sur le continent et qui est aujourd’hui menacée. Ces experts expliquent que la perte de la diversité du bétail en Afrique fait partie de « l’effondrement » mondiale du cheptel. Selon l’Organisation des Nations Unies pour l’alimentation et l’agriculture, près de 20 % des 7 616 races de bétail existant dans le monde sont aujourd’hui considérées comme à risque.

« L’élevage africain est un des plus robustes au monde, et pourtant nous assistons aujourd’hui à une dilution, si pas une perte totale, de la diversité génétique de nombreuses races, » dit Abdou Fall, chef du projet diversité animale de l’ILRI pour l’Afrique de l’Ouest. « Mais aujourd’hui, nous avons les outils nécessaires pour identifier les caractéres de grande valeur du bétail africain indigène, une information qui peut être cruciale pour maintenir, voire augmenter la productivité de l’exploitation agricole africaine. »

M. Fall décrit les différentes menaces qui pèsent sur la viabilité à long terme de la production de bétail en Afrique. Ces menaces comprennent une dégradation du paysage et le croissement avec des races « exotiques » importées d’Europe, d’Asie et d’Amérique.

Par exemple, on assiste à un croisement sur une très large échelle de races des zones sahéliennes d’Afrique de l’Ouest et susceptibles aux maladies avec des races adaptées aux régions subhumides, comme le sud du Mali, et qui ont une résistance naturelle à la trypanosomiase.

La trypanosomiase tue entre trois et sept millions de tètes de bétail chaque année et son coût pour les exploitants agricoles se chiffre en milliards de dollars, lorsqu’on prend en compte, par exemple, les pertes de production de lait et de viande, et les coûts de médicaments et prophylactiques nécessaires au traitement ou à la prévention des maladies. Bien que le croisement puisse offrir des avantages à court terme, comme une amélioration de la production de viande et de lait ou une plus grande puissance de trait, il peut également faire disparaître des caractères très précieux qui sont le résultat de milliers d’années de sélection naturelle.

Les experts de l’ILRI déploient à l’heure actuelle des efforts importants en faveur d’une campagne visant à maîtriser le développement d’une résistance aux médicaments chez les parasites qui provoquent la trypanosomiase. Mais ils reconnaissent aussi que des races dotées d’une résistance naturelle à cette maladie offre une meilleure solution à long terme.

Ces races comprennent les bovins sans bosse et à courtes cornes de l’Afrique de l’Ouest et du Centre, qui ont vécu dans cette région avec ces parasites pendant des millions d’années et ont ainsi acquis une résistance naturelle à de nombreuses maladies, y compris la trypanosomiase, propagée par la mouche tsétsé, et les maladies transmises par les tiques. De plus, ces animaux robustes sont capables de résister à des climats rudes. Mais les races à courtes cornes et à longues cornes ont un désavantage : elles ne sont pas aussi productives que les races européennes. Malgré ce désavantage, la disparition de ces races aurait des conséquences graves pour la productivité future du bétail africain.

« Nous avons observé que les races indigènes sans bosse et à courtes cornes d’Afrique de l’Ouest et du Centre font l’objet d’un abatage aveugle et d’un manque d’attention aux bonne pratique d’élevage, et risquent ainsi de disparaître,» explique Fall. « Il faut qu’au minimum nous préservions ces races soit dans le contexte de l’exploitation, soit dans des banques de gènes : leurs caractéristiques génétiques pourraient en effet s’avérer décisives dans la lutte contre le trypanosomiase, et leur robustesse pourrait être un atout essentiel pour des exploitants agricoles qui auront à s’adapter au changement climatique. »

Le Kuri aux grandes cornes bulbeuses du Sud Tchad et du Nord-est du Nigéria fait partie des bovins africains à risques. Non seulement il ne se laisse pas déranger par les piqûres d’insecte mais il est également un excellent nageur, vu qu’il s’est développé dans la région du lac Tchad, et est idéalement adapté aux conditions humides dans des climats très chauds.

Les actions de l’ILRI en faveur de la préservation du bétail africain indigène s’inscrivent dans un effort plus large visant à améliorer la productivité de l’exploitation agricole africaine au travers de ce qu’on appelle la « génomique du paysage ». Cette dernière implique entre autre chose, le séquençage des génomes de différentes variétés de bétail provenant de plusieurs régions, et la recherche des signatures génétiques associées à leur adaptation à un environnement particulier.

Les experts de l’ILRI considèrent la génomique du paysage comme étant particulièrement importante vu l’accélération du changement climatique qui impose à l’éleveur de répondre toujours plus rapidement et avec l’expertise voulue à l’évolution des conditions de terrain. Mais ils soulignent qu’en Afrique en particulier, la capacité des éleveurs à s’adapter aux nouveaux climats va dépendre directement de la richesse du continent en termes de diversité de son cheptel indigène.

« Nous assistons trop souvent à des efforts qui visent à améliorer la productivité du bétail dans la ferme africaine en supplantant le cheptel indigène par des animaux importés qui à long terme s’avéreront mal adaptés aux conditions locales et vont demander un niveau d’attention simplement trop onéreux pour la plus part des petits exploitants agricoles, » dit Carlos Seré, Directeur général de l’ILRI. « Les communautés d’éleveurs marginalisées ont avant tout besoin d’investissement en génétique et en génomique qui leur permettront d’accroitre la productivité de leur cheptel africain, car ce dernier reste le mieux adapté à leurs environnements. »

M. Seré souligne la nécessité de nouvelles politiques qui encouragent les éleveurs et les petits exploitants agricoles africains à conserver les races locales plutôt que de les remplacer des animaux importés. Ces politiques, dit-il, devraient comprendre des programmes d’élevage centrés sur la l’amélioration de la productivité du cheptel indigène comme alternative à l’importation d’animaux.

Steve Kemp, qui dirige l’équipe de génétique et de génomique de l’ILRI, ajoute que les mesures de conservation en exploitation doivent également s’accompagner d’investissements en faveur de la préservation de la diversité qui permettront de geler le sperme et les embryons. On ne peut en effet exiger du seul exploitant agricole qu’il renonce à une augmentation de la productivité au nom de la conservation de la diversité.

« Nous ne pouvons pas attendre de l’exploitant qu’il sacrifie son revenu avec pour seul objectif de préserver le potentiel de diversité, » explique M. Kemp. « Nous savons que la diversité est essentielle pour relever les défis auxquels l’exploitant africain est confronté, mais les caractéres de grande valeur qui seront importants pour l’avenir ne sont pas toujours évidents dans l’immédiat. »

M. Kemp recommande une nouvelle approche pour mesurer les ressources génétiques du cheptel. Aujourd’hui, dit-il, l’estimation de ces caractéristiques porte essentiellement sur des éléments tels que la valeur de la viande, du lait, des œufs et de la laine, mais elle ne prend pas en compte d’autres attributs qui pourraient avoir une importance égale, voire supérieure, pour l’éleveur, qu’il soit en Afrique ou dans une autre région en développement. Ces attributs comprennent la capacité d’un animal à tirer la charrue, à fournir de l’engrais, à faire office de banque ou compte d’épargne ambulant, et d’être une forme efficace d’assurance contre les pertes de récolte.

Mais l’association de ces multiples attributs avec l’ADN d’un animal exige de nouveaux moyens pour rechercher et comprendre les caractéristiques du cheptel dans une région caractérisée par une grande diversité et une grande variété d’environnements.

« On dispose aujourd’hui des outils nécessaires, mais nous avons besoin de la volonté, de l’imagination et des ressources avant qu’il ne soit trop tard, » indique M. Kemp.

Experts warn rapid losses of Africa’s native livestock threaten continent’s food supply

Posted on July 21, 2010 by Susan MacMillan

Resilient disease-resistant, 'ancient' West African cattle, such as these humpless longhorn N'Dama cattle, are among breeds at risk of extinction in Africa as imported animals supplant valuable native livestock

Urgent action is needed to stop the rapid and alarming loss of genetic diversity of African livestock that provide food and income to 70 percent of rural Africans and include a treasure-trove of drought- and disease-resistant animals, according to a new analysis presented today at a major gathering of African scientists and development experts.

Experts from the International Livestock Research Institute (ILRI) told researchers at the 5th African Agriculture Science Week (www.faraweek.org), hosted by the Forum for Agricultural Research in Africa (FARA), that investments are needed now to expand efforts to identify and preserve the unique traits, particularly in West Africa, of the continent's rich array of cattle, sheep, goats and pigs developed over several millennia but now under siege. They said the loss of livestock diversity in Africa is part of a global 'livestock meltdown'. According to the United Nations Food and Agriculture Organization, some 20 percent of the world's 7616 livestock breeds are now viewed as at risk.

'Africa's livestock are among the most resilient in the world yet we are seeing the genetic diversity of many breeds being either diluted or lost entirely', said Abdou Fall, leader of ILRI's livestock diversity project for West Africa. 'But today we have the tools available to identify valuable traits in indigenous African livestock, information that can be crucial to maintaining and increasing productivity on African farms.'

Fall described a variety of pressures threatening the long-term viability of livestock production in Africa. These forces include landscape degradation and cross-breeding with 'exotic' breeds imported from Europe, Asia and the America.

For example, disease-susceptible breeds from West Africa's Sahel zone are being cross-bred in large scale with breeds adapted to sub-humid regions, like southern Mali, that have a natural resistance to trypanosomosis.

Trypanosomosis kills an estimated three to seven million cattle each year and costs farmers billions of dollars each year in, for example, lost milk and meat production and the costs of medicines and prophylactics needed to treat or prevent the disease. While cross-breeding may offer short-term benefits, such as improved meat and milk production and greater draft power, it could also cause the disappearance of valuable traits developed over thousands of years of natural selection.

ILRI specialists are in the midst of a major campaign to control development of drug resistance in the parasites that cause this disease but also have recognized that breeds endowed with a natural ability to survive the illness could offer a better long-term solution.

The breeds include humpless shorthorn and longhorn cattle of West and Central Africa that have evolved in this region along with its parasites for thousands of years and therefore have evolved ways to survive many diseases, including trypanosomosis, which is spread by tsetse flies, and also tick-borne diseases. Moreover, these hardy animals have the ability to withstand harsh climates. Despite their drawbacks—the shorthorn and longhorn breeds are not as productive as their European counterparts—their loss would be a major blow to the future of African livestock productivity.

'We have seen in the short-horn humpless breeds native to West and Central African indiscriminate slaughter and an inattention to careful breeding that has put them on a path to extinction', Fall said . 'We must at the very least preserve these breeds either on the farm or in livestock genebanks because their genetic traits could be decisive in the fight against trypanosomosis, while their hardiness could be enormously valuable to farmers trying to adapt to climate change.'

Other African cattle breeds at risk include the Kuri cattle of southern Chad and northeastern Nigeria. The large bulbous-horned Kuri, in addition to being unfazed by insect bites, are excellent swimmers, having evolved in the Lake Chad region, and are ideally suited to wet conditions in very hot climates.

ILRI's push to preserve Africa's indigenous livestock is part of a broader effort to improve productivity on African farms through what is known as 'landscape genomics'. Landscape genomics involves, among other things, sequencing the genomes of different livestock varieties from many regions and looking for the genetic signatures associated with their suitability to a particular environment.

ILRI experts see landscape genomics as particularly important as climate change accelerates, requiring animal breeders to respond every more quickly and expertly to shifting conditions on the ground. But they caution that in Africa in particular the ability of farmers and herders to adapt to new climates depends directly on the continent's wealth of native livestock diversity.

'What we see too often is an effort to improve livestock productivity on African farms by supplanting indigenous breeds with imported animals that over the long-term will prove a poor match for local conditions and require a level of attention that is simply too costly for most smallholder farmers', said Carlos Seré, ILRI's Director General. 'What marginalized livestock-keeping communities need are investments in genetics and genomics that allow them to boost productivity with their African animals, which are best suited to their environments.'

Seré said new polices also are needed that encourage African pastoralist herders and smallholder farmers to continue maintaining their local breeds rather than abandoning them for imported animals. Such policies, he said, should include breeding programs that focus on improving the productivity of indigenous livestock as an alternative to importing animals.

Steve Kemp, who heads ILRI's genetics and genomics team, added that in addition to conservation on the farm, there must also be investments in preserving diversity by freezing sperm and embryos because farmers cannot be asked to forgo productivity increases solely in the name of diversity conservation.

'We cannot expect farmers to sacrifice their income just to preserve the future potential of diversity', Kemp said. 'We know that diversity is critical to dealing with the challenges that confront African farmers, but the valuable traits that may be important in the future are not always immediately obvious.'

Kemp called for a new approach to measuring the characteristics of livestock genetic resources. Today, he said, these estimates focus mainly on such things as the value of meat, milk, eggs and wool and do not include qualities that can be of equal or even greater importance to livestock keepers in Africa and other developing regions. These attributes include the ability of an animal to pull a plough, provide fertilizer, serve as a walking bank or savings account, and act as an effective form of insurance against crop loss.

But associating this wider array of attributes with an animal's DNA requires new ways of exploring and understanding livestock characteristics in a region where there is so much diversity in so many different environments.

'The tools are available to do this now, but we need the will, the imagination and the resources before it is too late', Kemp said.

ILRI workshop trains staff in social media for research communication

Posted on July 14, 2010 by Paul Karaimu

A workshop on ‘Africa Learning and Exchange on Local Content, Social Media and Agricultural/Rural Knowledge Sharing’ opened on the Nairobi campus of the International Livestock Research Institute (ILRI) last week.

From Monday through Wednesday, 5–7 July, the focus of the workshop was on ‘Research Communication’ and participants, who included ILRI staff and communication practitioners from research and non-profit organizations from Ethiopia, Uganda, Tanzania and Zimbabwe, were trained on use of social media tools in research communications. Participants also shared their experiences of using these tools.

The research communication workshop taught participants how to recover and disseminate research, identify and counter bias in search tools and use social media/web 2.0 tools and skills and approaches. Participants gained hands-on experience in working with wikis, creating blogs and adding content, using social bookmarking tools, such as Delicious, and using feeds to organize information from different web resources.

Participants also identified the challenges and opportunities offered by social media tools in Africa. They used a participatory wiki to document and share the workshop proceedings and edited and produced short video clips highlighting their views of the workshop.

Evelyn Katingi, a research coordinator with ILRI, said the workshop helped her ‘appreciate the value of social media tools in better organizing my work.’ She added ‘I look forward to using these tools in my work and in training others how to use them.’

A second part of the workshop, held 8–9 July, focused on sharing experiences of using modern online communication, social media and digital tools in gathering and sharing local African content. Participants included community radio hosts and managers, social workers and trainers who also explored how digital and online output from their organizations in Africa can be combined and promoted externally. The participants developed a shared understanding of how these tools and approaches can best be adapted to the African context to promote knowledge sharing.

Output from this week-long workshop, which was organized by ILRI and a Dutch-funded initiative, Emergent Issues in Information and Knowledge Management (IKM) and International Development, known as the IKM Emergent Research Programme, will inform preparation for an AgKnowledge Africa ShareFair that will take place at the ILRI campus in Addis Ababa in October 2010.

World’s first livestock insurance supports African herders

Posted on July 14, 2010 by Paul Karaimu

Drought is the greatest hazard facing livestock herders in Kenya. Their livelihoods have been greatly affected, and often devasted, by animal losses as a result of severe droughts, especially in the past 10 years.

In this 12-minute film, Andrew Mude, an economist working with the International Livestock Research Institute (ILRI), shares the story of a pilot project introduced in Marsabit District of northern Kenya in 2007 to provide a new and innovative livestock insurance scheme to Kenyan herders. The project is a result of joint research and collaboration by partners from different sectors, including private insurance companies, working in the region as well as institutions overseas.

This initiative is helping livestock keepers in some of Kenya’s most marginal areas to escape poverty and, as the film shows, has great potential to help other herding communities in Africa.

ILRI hosts Ethiopia workshop on index-based livestock insurance

Researchers call for regional approaches to deal with high food prices

Posted on July 6, 2010 by Paul Karaimu

Researchers in eastern and southern Africa are calling for a new regional and integrated approach to address high food prices associated with global food shortages. They are doing this to help prevent a repeat of the global high food price crisis of three years ago.

Under the leadership of the Association for Strengthening Agriculture Research in Eastern and Central Africa (ASARECA), a regional body that seeks to transform agriculture and improve livelihoods, a team of researchers from key national, regional and international organizations in eastern and southern Africa (ESA) have determined that a ‘regionally coordinated response . . . is potentially more effective in responding to the food price crisis than individual country responses.’

This is one of the key findings from a 2009 study that investigated food-price changes in the national and regional markets in eastern and southern Africa, which would provide an ‘evidence base for effective policy action.’

Joseph Karugia led a core team of researchers who were coordinated by the Regional Strategic Analysis and Knowledge Support System-East and Central Africa (ReSAKSS-EA), which is based in Nairobi, Kenya, at the International Livestock Research Institute (ILRI). Karugia says that ‘Regional blocks can become effective avenues for policy creation and implementation because they offer a much wider and stronger platform to address the challenges posed by the global food price crisis and to exploit the opportunities that high food prices may offer.’

Between 2007 and 2008, most countries in the region (and across the globe) experienced a rise in food prices that threatened the livelihoods of many of the region’s poor. Causes of the rise in prices were attributed to rising incomes and growing uses of food grains for bio-fuel production and animal feeds. In addition, an increasing world population and urbanization, coupled with high agricultural input prices, reduced world stocks of food staples and exports. Declining agricultural resources also contributed to the low supply of food.

Unlike past food-price spikes, such as those in the mid-1990s, where only a few commodities were affected, the recent rise in prices saw substantial increases in the price of the world’s key cereals, oilseeds and dairy and meat products.

For resource-poor farmers and consumers in Africa, high prices translated into higher costs of living occasioned by the increase in the prices of basic foods and staples such as maize, rice and wheat. Prices of different foods across many countries in the region went up by between 11 and 50 per cent between March 2007 and March 2008.

In the wake of the crisis, ASARECA brought a team of key researchers together in a study to find out ‘the magnitude and implications of food prices’ in the region. ‘One of our key aims was to come up with practical short-, medium- and long-term options for governments and other stakeholders for addressing the problem posed by the crisis,’ Karugia says.

The researchers analyzed trends and outlooks in individual countries as well as the region and presented evidence about the regional food situation. They also explored connections between high domestic food prices in this period and global food prices and examined regional and national dimensions of food-price increases and how they related to food security in the region.

From the study findings, presented in a paper, ‘Responding to the food crisis in eastern and southern Africa: policy options for national and regional action’, researchers argue that the considerable scope offered by regional blocks such as the East Africa Community (EAC), the Common Market for East and Southern Africa (COMESA), and the Southern Africa Development Community (SADC) provides an opportunity to create and implement regional policies and strategies to improve food production, distribution and availability in ways that individual countries could not handle alone.

The findings of this research suggest that new ways of approaching food distribution can improve food security in the region by for example, enabling improved regional trade that would allow easier movement of foods, especially ‘non-tradeable’ commodities such as bananas, shipped from countries where they are readily available to countries where consumers face food shortages. This model of food distribution could effectively deal with challenges that result from failure of staple crops such as maize. This way, the report says ‘the income effect of rising food prices could be dampened if it is relatively easy for the household to substitute one staple food whose price is already rising with a cheaper food product that is nutritious and as easy to handle as the previous one.’

Findings from this study provide thought-provoking perspectives useful to policymakers and governments in managing the frequent food crises in the region.

The findings highlight the important role of regional trade, Domestic food prices are, to a large extent, determined by local and regional demand-and-supply conditions; if policies on informal trade were improved, this region’s food security would also improve. The researchers note that an inability of households to find alternative cheaper nutritious foods would lead to ‘lower resource allocation towards non-food items’. This would then affect other sectors, such as education, health care and water and sanitation, with the ‘eventual deterioration of human capital and overall household welfare.’

Although rising food prices are contributing to food price inflation, the researchers note that the domestic markets in the ESA region are resilient and are not always directly affected by global events. Arguing that the best way to address the food price crisis is to do so regionally, they say policies should aim to ‘increase household purchasing power, have no negative impact on food supply response and should not reduce income of poor food sellers.’

This study calls for paying renewed attention to the agricultural sector, which is essential for improving production. It also notes that high food prices provide incentives to the private sector to invest in the agricultural sector. However, productivity increases will require significant and sustained investments in agricultural research and extension, as well as development of agricultural and general infrastructure along with credit and risk-management instruments.

New project to reduce chicken disease in Ethiopia

Posted on July 5, 2010 by Paul Karaimu

A new study of genetic resistance to disease in Ethiopia’s indigenous chicken breeds is scheduled to start later this year. In collaboration with the Ethiopian Institute for Agricultural Research, the University of Liverpool, Roslin Institute, the Univerisity of Edinburgh and the University of Nottingham, researchers from the International Livestock Research Institute (ILRI) will seek to identify ‘the causes of infectious diseases that have a major impact on poultry production in Ethiopia.’

Scheduled to start in September 2010, the study will take place in the district of Jarso, in eastern Ethiopia, and in Horro, in the west of the country. The results of this research will be linked to an ongoing poultry breeding program to improve resistance to ‘priority infectious diseases’ and thereby enhance the productivity of the country’s poultry sector.

Poultry play important economic, nutritional and socio-cultural roles in the livelihoods of poor rural households in Ethiopia and many other developing countries, where birds are widely integrated into smallholder production systems and help households cope with hunger and poverty.

Buying and rearing poultry is often a first step out of poverty. Women tend to own and manage chickens, usually native chicken varieties, which provide them with their only independent source of cash income.

Although breeding programs for local chickens have shown that rapid improvement in productivity is possible, researchers have yet to identify and select the optimal breeds for improving, by, for example, providing resistance to common infectious diseases.

Tadelle Dessie, a team leader of ILRI’s biotechnology theme in Ethiopia, and one of the leaders of the chicken project, says ‘enhanced genetic resistance through selective breeding is still an under-exploited low-cost opportunity for disease control in low-input poultry production systems’. He says the study will investigate genetic variability in the resistance of local chicken ecotypes to major infectious diseases hurting village poultry production in Ethiopia. Results of the research will inform strategies for improving both disease resistance and productivity.

Indigenous chicken varieties are well adapted to local environments, but local birds tend to grow slowly and produce fewer and smaller eggs than commercial varieties. Infectious diseases, however, can wipe out flocks of exotic, higher-producing, poultry.

Knowledge from this study should enable Ethiopian policymakers and animal health professionals to design more precise disease-control plans. The study itself should help improve Ethiopia’s scientific capacity in this field by training local scientists and enhancing laboratory facilities for poultry testing.

Staff are now being recruited for the project, which will be launched in September.

New participatory initiative to involve local communities in disease control

Posted on July 2, 2010 by Paul Karaimu

A new approach to disease surveillance and control aims to unite human and animal medical approaches to better control disease spread and so improve public health.

In this 10-minute film from the International Livestock Research Institute (ILRI), representatives of seven institutional members of a Participatory Epidemiology Network for Animal and Public Health (PENAPH), which includes researchers from ILRI, discuss ways of involving communities and health workers in the process of empowering local people.

The network uses participatory approaches to come up with effective ways of dealing with community challenges and encourages teamwork among farmers, veterinarians, nurses, doctors, governments and other specialists, especially in setting up effective disease surveillance systems.

Research shows bird flu still a threat to poultry production in Kenya

Posted on June 28, 2010 by Paul Karaimu

Risk assessment shows Avian Influenza still a threat to poultry production in Kenya

The risk of avian flu on poultry production continues to be a threat to the livelihoods of many poor and livestock-reliant farmers in developing countries such as Kenya, researchers say.

Scientists from the International Livestock Research Institute (ILRI) and the International Food Policy Research Institute (IFPRI) have found that poultry farmers in Kenya are ‘highly susceptible to the introduction and spread of the highly pathogenic avian influenza (HPAI)’ because of the country’s location along key wild birds’ migratory routes and the absence of strong mechanisms to deal with a possible outbreak of the disease.

Like in many developing countries, poultry production is an important livelihood activity in Kenya. Most poultry is kept by small-scale farmers in non-commercial settings, who depend on income from the sale of eggs, animals and meat to sustain their livelihoods.

Results from a 2009 impact assessment conducted by ILRI, IFPRI and the Royal Veterinary College in London with support from the Department for International Development (DFID) on the ‘Role of Poultry in Kenyan Livelihoods and the Ex Ante Impact Assessment of HPAI on Livelihood outcomes’ show that farmers in the key poultry producing regions of the country are not adequately prepared to deal with an outbreak of avian influenza.

Though the country has not had an outbreak of avian flu, there were two scares in 2005 and 2005. The scares led to a slowdown in the industry as farmers, in fear of making losses, reduced flock sizes by up to 40 per cent. The two scares also led to a depressed market for poultry and poultry products and lowered the prices which negatively impacted farmers. The assessment showed that farmers in Kenya are still at risk especially because the country’s human and animal health services are not adequate. Coupled with the fact that most of the poultry farming in the country is a ‘backyard poultry system’ preventing and controlling disease outbreaks would be significantly difficult.

Among others, the results of the assessment also showed, like other studies had confirmed, that poultry production is largely done by women and children to support livelihoods and that most of the poultry in Kenya is produced in the country’s western and eastern regions. Farmers in these places are most at risk of loses in the event of a HPAI outbreak. Kenyan farmers keep an average flock size of 18 birds across the country but there are significant variations across regions mostly determined by ease of access to markets. Nairobi province, for example, has large producers (though fewer in number compared to other regions) with an average of 158 birds per flock because of access to ready market for their animals.

The assessment found that ‘households with “larger” small-scale flocks as well as those located in high risk areas (Western, Nyanza and parts of Eastern provinces) are vulnerable to HPAI. In the event of an outbreak, the disease would cause ‘significant reduction in livestock income and wealth (asset value) and total annual household income would be reduced.’

The results of this assessment were first published as ‘The role of poultry in Kenyan livelihoods and the ex ante impact assessment of HPAI on Livelihood outcomes’ by the International Food Policy Research Institute (IFPRI).

Livestock: ‘Polluters of the Planet’ or ‘Pathways out of Poverty’? A public debate

Posted on June 25, 2010 by Susan MacMillan

Two development experts recently debated the ‘public goods’ and ‘bads’ of global livestock production. They debated the question, ‘Should we eat less meat to increase food security’, in a ‘Spat’ column in the current (June 2010) issue of People and Science, published by the British Science Association.

Arguing ‘no’ (with reservations) is John McDermott, a Canadian veterinary epidemiologist who serves the Africa-based International Livestock Research Institute (ILRI) as Deputy Director General for Research. Arguing ‘yes’ (also with reservations) is Vicki Hird, a Senior Food Campaigner at Friends of the Earth, a UK-based environmental non-governmental organization.

The missions of both ILRI and Friends of the Earth have much in common. Both organizations, for example, are investigating ways to reduce climate change. And both want to manage natural resources in ways that conserve as much land, water, biodiversity and air as possible, with everyone getting a ‘fair share’ of those resources.

But when it comes to their views on livestock — as to whether cows, sheep, goats, pigs and other farm animals do more good than bad, or more bad than good, for people and their environments — each of these development experts sees livestock from a different perspective.

For Hird, who lives in Europe — where environmental concerns are major issues, and where the public embraces environmental causes and activism — livestock are largely ‘polluters of the planet’.

For McDermott, who lives in East Africa — where people’s greatest concerns are getting a job, putting food on the table and paying school and medical fees, a region where development concerns take centre stage — livestock represent ‘pathways out of poverty’.

As one might expect, Hird takes a ‘global’ and ‘environmental’ view of the impacts of livestock production, focusing on the inhumane industrial ‘factory farms’ of industrialized countries, the over-consumption of fatty meat by the rich, and the rape of South American forests to make room for cattle, sheep and goat ranches or for growing soy to feed pigs in Europe. Additionally, there is a growing push for sustainable practices, such as installing solar panels for factory operations, to reduce the carbon footprint of such industries. McDermott, also as one might expect, takes the perspective of the world’s 450 million small farmers, who raise their animals on grass and crop wastes rather than grain, whose children don’t yet eat enough meat, milk and eggs, and whose livelihoods depend directly on the natural resources they have at hand.

Both of these development experts, perhaps surprisingly, also agree on quite a lot when it comes to livestock. They agree that factory farming practices are becoming more and more unsustainable as well as inhumane; they agree that most people in rich countries would profit from eating less fatty meats; they agree that South America’s forests should not be felled so that rich people can eat more pigmeat; and they agree that finding more sustainable as well as equitable ways of producing livestock is in the general public interest.

What the debate focuses on, then, is not so much what to do but how to do it. And, as we shall see, on how long that should take.

McDermott argues for giving small farmers ‘incentives’, for example, to redistribute livestock herds or to intensify their crop-plus-livestock farming systems in ways that make more efficient use of natural resources.

Hird argues for more regulation of the livestock industry in richer countries in areas such as farm subsidies and taxation, and for raising awareness of the major environmental, social and health problems that livestock systems can cause so as to change public (meat-eating) behaviour.

McDermott thinks our biggest job is ‘to close the selective-evidence divide on both sides of the debate’ by getting more evidence in key areas; some industrial practices, he points out, make ‘very efficient’ uses of environmental resources. To come up with equitable policies in the global livestock sector, McDermott argues, will require better assessments — and at much more local levels — of the differing socio-economic as well as environmental trade-offs of those policies. ‘Before taking broad action’, he says, ‘we should use the best available knowledge to design and test interventions in pilot studies’.

Hird is impatient ‘to wait for a perfect evidence base’ before acting and says they have ‘presented a Sustainable Livestock Bill in Parliament to kick start the dialogue on vital UK action’.

In brief, Hird appears most interested in quickly getting to ‘less’ livestock intensive production’ and McDermott in developing long-term ‘smarter’ livestock intensive production’.

Let us know below what you think.

International Livestock Research Institute

In a new 2-minute filmed interview on the ‘goods’ and ‘bads’ of livestock by the International Livestock Research Institute (ILRI), scientists Phil Thornton, of ILRI, and Andy Jarvis, of the International Centre for Tropical Agriculture (CIAT), in Colombia, give their views on whether giving up eating meat altogether would help to save the environment. They describe the importance of livestock to the livelihoods of one billion of the world’s poor and caution that removing livestock from the environment would have its own effects. These scientists shared their views during the launch of a new initiative by the Consultative Group on International Agricultural Research (CGIAR) called ‘Climate Change, Agriculture and Food Security.’
