Climate change impacts on pastoralists in the Horn: Transforming the ‘crisis narrative’

Shiferaw Teklemariam, Ethiopian Minister of Federal Affairs, opened a ‘Future of Pastoralism in Africa’ Conference yesterday (21 March 2011), which is organized by Tufts University and Future Agricultures Consortium and being held on the Addis Ababa, Ethiopia, campus of the International Livestock Research Institute (ILRI). The Minister’s talk was followed by that of Abebe Haile Gabriel, director of the African Union Department of Rural Economy and Agriculture who reminded his audience that ‘Pastoralism is nothing new but is continually forgotten.’

Ian Scoones, of the Future Agricultures Consortium and the Institute of Development Studies at Sussex University, then set the scene for the conference with remarks such as the following. ‘There is a moment now, with renewed interest in pastoralism in the Africa Union, regional bodies and national governments, for evidence-based research to inform policy. Even a decade ago, we would have been urging governments and the Africa Union to give pastoralism attention. They are now taking pastoralism seriously, as a driver of growth. . . . This meeting comes in a long lineage of meetings discussing the future of pastoralism in Africa. (A meeting in 1951 in Niamey was an early one.) But recently, there has been massive change and dynamism in this continent’s pastoral areas. . . . Popular reports on pastoralism are dominated by crisis narratives. While the popular discourse continues with doom and gloom scenarios, we see dynamic change with growth—as in the livestock trade booms in the borderlands—with both winners and losers. . . .

‘The research on pastoralism in Africa has a rich tradition. Among the more classic works are the optimism displayed in the 1960s and 1970s about the transformation of pastoralism; 1980s work done by ILRI’s predecessor, ILCA (International Livestock Centre for Africa), on the Borana pastoralists of Ethiopia; the 1990s’ focus on land tenure issues and ‘disequilibrium’ in rangelands; the attention given by CRSP (Collaborative Research Support Program) and others to pastoralist poverty and livelihoods; recent emphasis on the marketing and commercialization of pastoralist livestock products; and today’s attention to the impacts of climate change, conflict and insecurity on pastoral communities. . . .

‘We want in this workshop to build on this huge body of work, to reflect on it, and to judge how robust were those findings. We want to know what new insights are suggested by today’s research and what they suggest for policymaking. . . . We want to offer possible scenarios for pastoralist areas and to do so we want to try out a simple approach. This simplistic diagram categorizes pastoralists according to whether their access to markets and resources is good or poor, as in the following.

  1. Where pastoralist access to both markets and resources is good, there is potential for commercialization and export trade.
  2. Where pastoralist access to both markets and resources is poor, communities should seek alternative livelihood strategies and ways to exit pastoralism.
  3. Where pastoralist access to resources is good but to markets is poor, traditional mobile pastoralism should continue to dominate.
  4. And where pastoralist access to markets is good but to resources is poor, ways of diversifying livelihoods and adding value to livestock products is needed.’

Impacts of climate change on pastoralist communities
Several ILRI scientists participated in a session after lunch on the impacts of climate change on pastoralism. These included Polly Ericksen, who made a presentation, Shirley Tarawali, Jan de Leeuw, Andrew Mude and David Nkedianye. The latter, a Maasai who worked with ILRI while doing his doctoral research, also made a presentation.

Polly Ericksen, of ILRI, reminded her audience that managing climate variability and climate risk is at the very heart of pastoralism. The consequences and implications of climate change are therefore of paramount importance to pastoral livelihoods, production systems and landscapes. The paper developed by Ericksen—along with her ILRI colleagues Phil Thornton, Augustine Ayantunde, Mario Herrero, Mohamed Said and Jan de Leeuw—explores what we do and do not know about how climate change will unfold in pastoral areas of sub-Saharan Africa. And it stresses the importance of successful strategies for adapting to climate change at local as well as higher governance levels for the future of pastoralism.

Among other remarks from Ericksen were the following. ‘Pastoralists of course manage well the considerable changes in climate that they experience. Pastoralism is a supreme adaption to managing climatic variability. . . . The 2009 drought in Kenya killed up to 80% of the livestock kept by the country’s pastoralists. . . . Many crop farmers in Africa’s drying regions will start to incorporate more livestock, a trend that has been occurring in West Africa for the last 2 to 3 decades. . . . New research shows that, contrary to IPCC estimates, the Kenya highlands have been getting drier and are likely to continue to dry. There is fundamental uncertainty regarding the impacts of climate change—not least because we don’t even know how we humans will manage ourselves in the face of climate change.’

Remarks by Gufu Oba, of the Norwegian University of Life Sciences: ‘The variability of Africa’s drylands—season to season, year to year, place to place—makes nonsense of theories of “carrying capacity”. . . . Pastoralists do not run away from risks: they face them straight on. And communities and individuals differ greatly in how they cope with threats. . . . Pastoralism will be less mobile in future, but pastoralism will survive: herders will not exchange their lava rocks and other dryland features for anything.’

David Nkedianye, heading a non-governmental organization called ‘Reto-o-Reto’ (‘I help you, you help me’ in the Maa language) in Kenya’s Kitengela rangeland region, in his presentation said that lack of land tenure and land use policies, increasing demographic pressure, growing rural-to-urban migration, insecurity and lack of a cross-bornder migration framework are some of the key issues to be tackled soon if pastoralism is to survive into the future. Lessons from southern Kenya indicate that trends in land fragmentation and radical policies on land use have been difficult to change. Going by the going rates and direction,  pastoralism is headed for harder times in the future. Nkedianye also said the following: ‘Lands in Kajiado are being privatized and fragmented much faster than those in Narok, with huge land speculation going on. . . . In Kajiado in the great drought of 2008/9, only herders able to move to the wetter north were able to save some of their stock. . . .

‘The irony is that as we open up more and more rangelands by providing roads and other basic infrastructure, more people will move in, which will reduce pastoral mobility even more. . . . We need to be consistent and relentless in our policy messages and to promote our women and our adolescents. Two things that are making a big difference in my part of Kenyan Maasailand [Kajiado] are education and Christianity. . . . Pastoralists have “exited” pastoral livelihoods since time immemorial but the present inability of many herders who have lost their animals to go back into pastoral ways of life once they have rebuilt their herds is perhaps new. . . . We have to come to terms with longer term pressures, particularly demographic. . . . Cell phones have changed pastoralism a lot. But more important are that rich people have richer connections.’

Terry McCabe, of the University of Colorado, reminded the group that the biggest shock to East Africa’s pastoralists in more than one hundred years was not climate change but disease—specifically the great rinderpest plague of the end of the 19th and beginning of 20th centuries, which killed whole populations of wild and domesticated animals and led to the starvation of many herding communities.’

The Future Agricultures Consortium and the Feinstein International Center at Tufts University jointly organized this conference to assess ongoing change and innovation in Africa’s pastoral areas. Researchers, policymakers, field practitioners and donor representatives at this conference are assessing the present and future challenges to African pastoralism to define new research and policy agendas.

The future of pastoralism in Africa debated in Addis: Irreversible decline or vibrant future?

An international conference deliberating the future of pastoralists in Africa is taking place this week (21–23 March  2011) at the Addis Ababa, Ethiopia, campus of the International Livestock Research Institute (ILRI).

Big changes are occurring in, and to, Africa’s vast pastoral regions. Livestock herders’ access to resources, options for mobility and opportunities for marketing are all evolving fast. Is there, the organizers of this conference ask, opportunity for a productive, vibrant, market-oriented livelihood system or will pastoralist areas remain a backwater of underdevelopment, marginalization and severe poverty?

The Future Agricultures Consortium, an alliance of agricultural development researchers and practitioners that facilitates policy dialogues and debates on the role of agriculture in broad-based African growth, and the Feinstein International Center at Tufts University, which also has a mixed staff of development researchers and practitioners, have jointly organized this conference to share new learning about ongoing change and innovation in Africa’s pastoral areas.

One of the aims of the conference organizers is to shift the crisis narrative that so often dominates news and discussions of pastoralists in Africa. As noted on the Future Agricultures Consortium website: ‘Frequently depicted as in crisis, pastoralists are changing the way they live and work in response to new opportunities and threats revealing the resilience that pastoralists have demonstrated for millennia. Accessing new markets and innovating solutions to safeguard incomes, this often misunderstood and marginalised community is re-positioning itself to make the most of the East African economy. . . .

‘The pastoralist way of life—synonymous with irreversible decline, ‘crises’ and aid rescues—is poorly understood. And whilst the words ‘pastoralism’ and ‘crisis’ have become fused in the minds of many, there are positive signs of vibrant pastoralist livelihoods that debunk the usual reportage of pastoralists depicted as insecure, vulnerable and destitute. . . .

‘Failed by generations of unsuccessful state development plans and aid strategies, pastoralists have been let down because the real problems and issues they face have not been taken into account. A more accurate understanding of the processes of change happening within pastoralist areas, which are significant and complex, has been obscured by the perpetuated myths of pastoralism in crisis.

‘Understanding the complexity and potential for pastoralism is crucial to informing policies for securing the future of this age-old and resilient sector in sub-Saharan Africa.’

Hot topics
The new research and practical experiences being shared at this conference are on the following hot topics in academic and development research.
Regional pastoralist policies (and the politics of pastoralist policy)
Mobility and the sustainability of pastoralist production systems
Impacts of climate change on pastoralism
Commercializing pastoralism through better markets and trade
Delivering basic health, education and veterinary services to pastoralists
New approaches for strengthening pastoralist livelihoods and social protection systems
Alternative livelihoods and exit strategies for pastoralists
Pastoralist views of land grabbing and land tenure
Pastoralist innovations
How conflicts are affecting pastoralist development in the Horn of Africa
The place, and potential, of youth and women in pastoralist societies

Researchers, policymakers, field practitioners and donor representatives at this conference are assessing the present and future challenges to African pastoralism so as to begin to define new research and policy agendas.

New program aims to spur state-of-the-art biosciences innovation to fight food insecurity, climate change and environmental degradation across eastern Africa

Bio-Innovate launch: Swedish Embassy's Bjorn Haggmark

Launched today at the International Livestock Research Institute (ILRI), the Bioresources Innovations Network for Eastern Africa Development (Bio-Innovate) program will support the fight against food insecurity in eastern Africa (photo credit: ILRI/MacMillan).

A new program that provides grants to bioscientists working to improve food production and environmental management in eastern Africa was launched today at the Nairobi headquarters of the International Livestock Research Institute (ILRI).

The newly established Bioresources Innovation Network for Eastern Africa Development (Bio-Innovate) Program—the first of its kind in Africa—provides competitive grants to African researchers who are working with the private sector and non-governmental organizations to find ways to improve food security, boost resilience to climate change and identify environmentally sustainable ways of producing food.

In its first three-year phase, the program is supporting five research-based projects working to improve the productivity of sorghum, millet, cassava, sweet potato, potato and bean farmers; to help smallholder farmers adapt to climate change; to improve the processing of wastes in the production of sisal and coffee; and to better treat waste water generated in leather processing and slaughterhouse operations.

In its second three-year phase, beginning mid-2011, Bio-Innovate will help build agricultural commodity ‘value chains’ in the region and a supportive policy environment for bioresource innovations.

The five-year program is funded by a USD12-million grant from the Swedish International Development Agency (Sida). Bio-Innovate is managed by ILRI and co-located within the Biosciences eastern and central Africa (BeCA) Hub at ILRI’s Nairobi campus. Bio-Innovate will be implemented in Burundi, Ethiopia, Kenya, Rwanda, Tanzania and Uganda.

‘By emphasizing innovations to help drive crop production in the six partner countries, Bio-Innovate is working at the heart of one of the region’s greatest challenges—that of providing enough food in the face of climate change, diversifying crops and addressing productivity constraints that are threatening the livelihoods of millions,’ said Carlos Seré, ILRI’s director general.

An increasingly large number of poor people in the developing world are hungry, or, in development-speak, ‘food insecure.’ In sub-Saharan Africa, where agricultural production relies on rainfed smallholder farming, hunger, environmental degradation and climate change present a triple threat to individual, community and national development. In eastern Africa alone, over 100 million people depend on agriculture to meet their fundamental economic and nutritional needs.

Although some three-quarters of the African population are involved in farming or herding, investment in African agricultural production has continued to lag behind population growth rates for several decades, with the result that the continent has been unable to achieve sustainable economic and social development.

‘Bioresources research and use is key to pro-poor economic growth,’ says Seyoum Leta, Bio-Innovate’s program manager. ‘By focusing on improving the performance of crop agriculture and agro-processing, and by adding value to primary production, we can help build a more productive and sustainable regional bioresources-based economy.’

Bio-Innovate works closely with the African Union/New Partnership for Africa’s Development (AU/NEPAD) and its new Planning and Coordinating Agency, as well as with the councils and commissions for science and technology in eastern Africa, to encourage adoption of advances in biosciences. The program builds on AU/NEPAD’s Consolidated Plan of Action for Africa’s Science and Technology and the Comprehensive Africa Agriculture Development Program (CAADP).

‘African governments are appreciating the importance of regional collaboration,’ says Ibrahim Mayaki, the chief executive officer of NEPAD. ‘Collaborations such as this, in science and technology, will enable the continent to adapt to the rapid advances and promises of modern biosciences.’

Bio-Innovate has already established partnerships with higher learning institutions and national agricultural research organizations, international agricultural research centres and private industries working both within and outside eastern Africa.

‘Bio-Innovate is an important platform for pooling eastern African expertise and facilities through a regional Bioresources Innovations Network,’ says Claes Kjellström, Bio-Innovate Sida representative at the Embassy of Sweden in Nairobi. ‘We believe this program will enable cross-sectoral and interdisciplinary biosciences research and enhance innovations and policies that will advance agricultural development in the region.’

The Bio-Innovate team is working with these partners to help guide development and adoption of homegrown bioscience policies in its partner countries and to spread knowledge of useful applications of bioscience. In the coming years, Bio-Innovate staff envision eastern Africa becoming a leading region in the use of biotechnology research and approaches for better food production and environmental management.

New Bio-Innovate Program is good news for bio-scientists in ‘bio-rich’ eastern Africa

A new program called Bio-Innovate, which stands for ‘Bioresources Innovations Network for Eastern Africa Development,’ is being launched tomorrow (Wednesday 16 March 2011) at the Nairobi, Kenya, campus of the International Livestock Research Institute (ILRI).

Funded by the Swedish International Development Agency (Sida), Bio-Innovate offers competitive funding for biosciences and innovations in six countries of eastern Africa through a Bioresources Innovation Fund. The program accepts applications for regional, multi-disciplinary innovation projects in Burundi, Ethiopia, Kenya, Rwanda, Tanzania and Uganda.

More than 80 people—including scientists, policymakers, development practitioners and staff from private companies, donor agencies and diplomatic missions—are expected to participate. They represent national agricultural research organizations and universities, national councils for science and technology, regional bodies and international organizations from within and outside the region.

We interviewed two of the key people, Seyoum Leta, Bio-Innovate’s program manager, and Gabrielle Persley, senior advisor to ILRI’s director general, to tell us what Bio-Innovate is all about. Watch these short interviews below.

And follow the launch tomorrow on the web using the search term #BioInnAfrica2011.

Bio-Innovate Bean Technology Consortium

Seyoum Leta, Bio-Innovate program manager, is interviewed in the following brief films.

Film 1—Bio-Innovate: Addressing the missing link between research and innovation
East Africa has never had the facilities, funding or skilled manpower to undertake agricultural science on a scale that could move from research all the way to new technologies for farmers. Bio-Innovate is a new program aiming to provide that ‘missing link’. It will tackle the big regional problems such as climate change results, and environmental degradation, by the application of bio-sciences, with the direct aim of helping small-scale farmers.

Film 2Over 3 million farmers could benefit from the first projects of a new initiative
Small-scale farmers in 6 East African countries will be the first in the region to benefit from the new Bio-Innovate program. The first projects in the scheme will tackle challenges like the development of more productive varieties of staple crops, and waste re-cycling. Over the next 5 years, the numbers of projects will expand, using Bio-Innovate’s promotion of improvements in policy frameworks, its networks of scientists and research organizations, and the novel links it is building with private sector companies.

Film 3Launching a unique African-based and African-led program on innovations and policy analysis in eastern Africa
16 March 2011 is the official launch date for Bio-Innovate, a unique regional agricultural research initiative that is Africa based, Africa led and focuses on innovations for farmers.

Gabrielle Persley, Senior Advisor to the Director General

Gabrielle Persley, senior advisor to ILRI’s director general, is interviewed in the following brief films.

Film 4New phase of African Bio-Innovate Program will soon deliver solutions to farmers
Bio-Innovate is building on a previous project that trained 20 regionally recruited bioscientists to PhD level. Now the new program plans to move from research outputs into partnerships with private sector players and other delivery mechanisms. The real focus and the success of Bio-Innovate will be delivery of products to African farmers.

Film 5New science program makes use of facilities and expertise at the first biosciences hub in Africa
The choice of location for the headquarters of Bio-Innovate depended on access to the best bioscience facilities and expertise in the region. The Biosciences eastern and central Africa (BecA) Hub, at the ILRI Nairobi campus, provides a vibrant biosciences research platform for advanced research into crops and livestock.

Film 6Bioscience support plus field trials will lead to the development of practical technologies for farmers
Core elements of the work of the Bio-Innovate projects will be done in the field. Through building partnerships within the participating countries, national research programs and the local private sector, evaluation of potential products in the field and scaling up can be targeted to local needs.

Film 7Large African bioscience-based agricultural project targets key famine-type foods and environments
Funding of USD10 million over 5 years will allow projects sponsored by Bio-Innovate to reach the critical mass of financial, agricultural and research resources needed to tackle large-scale regional challenges such as climate change and environmental degradation. In this way Bio-Innovate will help improve food supplies and incomes for small-scale farmers.

Forestalling the next plague: Building a first picture of all diseases afflicting people and animals in Africa

Typical mixed crop-livestock farming of western Kenya

An ILRI-Wellcome project is investigating the disease pathogens circulating in both people and animals in the communities outside the border town of Busia, Kenya, where smallholders mix crop growing with livestock raising (photo credit: ILRI/Pye-Smith).

A project funded by the Wellcome Trust on zoonotic diseases was broadcast last week on an Australian television program called ‘Catalyst’. The show ran on Thursday, 10 March 2011, at 20:00 Australian time. The research described in the program is supported by the International Livestock Research Institute (ILRI), where the project’s principal investigator, Eric Fevre, is hosted.

The television program interviews Fevre and his colleagues Lian Doble, a veterinarian managing laboratory work in western Kenya, and  Appolinaire Djikeng, technology manager of a Biosciences eastern and central Africa (BecA) Hub, located on ILRI’s Nairobi, Kenya, campus.

Fevre and Doble and their team are investigating what disease pathogens of both people and animals are circulating near the border town of Busia, a very poor, densely populated area whose communities mix crop growing with livestock raising on small plots of land. Research such as this that is looking at both human and animal diseases is rare but urgently needed because the close relations of people and farm animals in many poor regions, as well as the existence of monkeys and other wildlife nearby, is a ‘recipe for diseases’ jumping from animals to people. If we’re going to manage to forestall another zoonotic plague such as bird flu or HIV/AIDS, we’re going to have to conduct more of such ‘one health’ investigations that look at exactly what diseases are being transmitted between animals and people. The research project in western Kenya is part of a larger study being conducted by the BecA Hub to look at diseases of animals and people across eastern Africa. The BecA Hub team is using genomics and meta-genomics, and ‘4 million bucks of computing power,’ to build a picture of the complex relations of disease pathogens circulating in the region.

A transcript of the Australian television program on this research follows.

NARRATION
Africa, the cradle of humanity and renowned for its wildlife. It could also be the origin of the next global pandemic. It’s long been known that people and animals living close together—well, that’s a recipe for disease. But exactly which diseases? And if new diseases are creeping into the system? Well, that’s something they’re trying to find out here in western Kenya. They’re called zoonotic diseases: infections that can jump from animals to people.

Eric Fevre
There are lots of zoonotic infections. In fact, about 60 per cent of all human diseases are of zoonotic origin.

NARRATION
So this team headed by Eric Fevre is taking a much closer look at the health of people and livestock in a densely populated region of western Kenya.

Eric Fevre
It seems to be obvious that zoonotic infections will occur more in people who keep livestock than in those who don’t. Whether that’s the case has never been formally established.

Lian Doble
If you look around here you don’t see the cattle in a field, in a fenced field or in a barn away from the people. Cattle are tethered within the compound that everybody’s working in, the chickens are loose around, going in and out of the houses. It’s a much more integrated system than anything we really see at home.

NARRATION
The kinds of problems that this environment creates are readily apparent.

Eric Fevre
We’re in a mixed crop-livestock production system where people are keeping a few animals. And as you can see behind me here, it’s the rainy season and people have recently planted their new crops. And this is an area of interaction between the croplands and the animals. And you can see behind over there behind those fields is some forest. And there might be a watercourse flowing through that forest, for example, where the animals are going to water. And that’s where the exciting things happen from a disease transmission point of view.

NARRATION
Part of the team focus on human health, taking a range of samples from people in the village as well as a detailed account of their medical history and current living situation. Meanwhile, others in the team have a look at the livestock.

Lian Doble
What we do know is that there are a large number of diseases that circulate between animals and humans. The problem is that a lot of these diseases cause signs which are very similar to other human diseases like malaria and human tuberculosis. What isn’t known is actually how many of the diseases that are mainly diagnosed as malaria actually are another disease caused by the pathogens found in cattle. So we’re just trying to find out what diseases she has and what are shared with the people that she lives with.

Paul Willis
And does she look healthy?

Lian Doble
She’s feisty and she’s quite healthy so we’ll see what she might have been carrying. And we can tell you later in the lab.

NARRATION
Samples are taken back to field laboratories in the town of Busia on the Ugandan border.

The ILRI-Wellcome Trust laboratory in Busia, Kenya

Eric Fevre
In this place we’ve got a human and an animal lab next door where we process the material that comes in from the field. One of the things that we really need to do is look at fresh material. Because once the samples get a bit old, the parasites become a bit difficult to identify. And the second important thing is that we of course feed back to the participants of our study. So results that we get in the lab here are used directly by the clinicians working in the field to decide what treatments they should be giving people. So that’s one of the direct ways that our research project feeds back into the community.

NARRATION
This detailed look at the community health of a whole region is showing many expected results, and a few surprises.

Eric Fevre
One of the diseases that we’re testing for is brucellosis. And looking at the official reports there isn’t any brucellosis in this region. But we have detected brucellosis both in animals and in people and so already that’s what’s telling us that there are things circulating here that official records don’t pick up.

NARRATION
There seems to be a lot of malaria around, but Eric’s team are finding that many cases are masking something much more sinister.

Eric Fevre
Often it won’t be malaria. It will be something else. And there are a multitude of different pathogens that cause fever of the type that malaria also causes. And that’s a real problem. Because somebody with a low income might need to, say, sell one of their animals to then go to the clinic, get a diagnosis, buy some anti-malarial drugs. They don’t work because the person actually has sleeping sickness. So they go back to a different clinic. Or to a traditional healer. They get drugs that don’t work for the infection that they have. And so on and so on, five, six, seven times, travelling maybe ten kilometres each time. That’s a huge economic burden on them. And then finally they get properly diagnosed when they’re in the late stage of their infection. And it would have been much easier to treat them if they’d have been caught earlier on.

NARRATION
It’s a very complex picture that is emerging, one that could be simplified by some basic technology.

Lian Doble
Thirty per cent of our participants don’t have access to a latrine. You can imagine what that means. And that’s something that could be very actually quite easily sorted out with some education and some money and would sort out all sorts of other diarrhoeal diseases, which are one of the huge killers of young children in Africa.

NARRATION
Back in Nairobi another team is taking a different look at the spread of diseases across east Africa.

NARRATION
Appolinaire Djikeng heads up a team collecting samples of animals and people from a wide swath across Kenya.

Appolinaire Djikeng
So essentially at the moment we are trying to cover the east African region. But of course we would like to once we establish our processes and data management skills and data analysis skills we like to expand this to other parts of Africa.

NARRATION
The first step in the labs is to figure out exactly what spread of diseases are present in their samples.

Appolinaire Djikeng
You are able to go in there, look at the, the complex composition of the viruses, at the pathogens or at the small organisms that exist in them in doing it that way you are able to come up with a catalogue of potential organisms that exist in there.

NARRATION
And this analysis goes deep into the DNA of the viruses and pathogens that are found, tracking minute changes in their genetic make-up that allows Appolinaire’s team to follow the spread of individual strains of a disease.

Appolinaire Djikeng
We have a reasonably good bioinformatic infrastructure here for storing that data and extracting them, looking at specific parameters from that particular data base. With so many samples from such a wide geographical area and with so much information for each individual sample these guys are dealing with a lot of data and so they brought in four million bucks worth of computing grunt. With so many samples from such a wide geographic area and with so much information for each individual sample these guys are dealing with a lot of data. So they brought in four million bucks worth of computing grunt.

NARRATION
There are several teams looking at zoonotic diseases in Kenya, but the impact of their work is global.

Appolinaire Djikeng
The threat of emerging and re-emerging infectious diseases are no longer restricted to countries like central Africa or sub-Saharan Africa So I think now we have to put this work in the context of the global effort across the world. Trying to make sure that even remote parts of the area do have resources and capabilities to begin to do good and accurate diagnostics of what could be emerging.

Eric Fevre
We actually use the data that we gather to, to try and understand how these things are being transmitted, how the fact that your animal has this disease impacts on your risk at a population scale. And, and use that to then try and understand the, the process of transmission of these diseases.

Lian Doble
The next big disease problem is very likely to be a zoonotic disease so doing this sort of work and then leaving it isn’t an option. It needs to be ongoing and, and build. This is the start of something and we’ll build on it from here.

And check out a blog by Paul Willis about the adventures of filming in Kenya’s border town of Busia: Coming to an end, 7 March 2011.

Here’s some of what Paul Willis has to say in his blog about this film project:
‘Busia is a hard place; a border crossing town riddled with grinding poverty and hard living. The main street, the only sealed road through town, is frequently clogged with a seemingly endless string of trucks waiting to cross the border into Uganda. Because Uganda, Rwanda and Burundi are all landlocked nations, every drop of fuel and most freight coming into the country has to be trucked in from Mombasa and most of that comes through Busia. . . . This area of Kenya has some of the most intensively farmed land in East Africa. The whole landscape is divided into small plots with clusters of mud and thatch huts scattered among them. Here people live cheek-by-jowl with their crops and animals. It’s a recipe for diseases to jump from animals to people. Add strips of forested vegetation inhabited by a variety of monkeys and other native mammals and the chances of new diseases leaping into the human population goes up dramatically. We’re here to report on the work of a dedicated group trying to get a handle on exactly what diseases are in this chaotic system. It’s hard work, in one of the hotter areas of Kenya, and the study is spread over a huge area. . . .’

‘Unlocking the value of the cow’: New project to identify the best breeds for East Africa’s small-scale dairy producers

A new project identifying appropriate dairy breeds for small-scale farmers in East Africa, and making these breeds more available in the region, was launched in February 2011 at the Nairobi campus of the International Livestock Research Institute (ILRI). The Dairy Genetics East Africa project—a partnership between ILRI; the University of New England, in Australia; and PICOTEAM, a consultancy group facilitating change processes—will help smallholders obtain the most appropriate cows for their farms so as to increase their milk yields and improve their livelihoods.

Speaking to dairy stakeholders from Kenya, including officials from Kenya’s Ministry of Livestock Development, the East Africa Dairy Development (EADD) project and other dairy industry development partners, at the launch on 9 February 2011, Okeyo Mwai, a researcher and the project’s coordinator at ILRI, explained that even though smallholder dairying is booming in parts of East Africa, such as in Kenya’s central region and the north and southern Rift Valley areas, where farmers have adopted improved animal breeds and intensified milk production, many more smallholders lack research-based knowledge about which dairy breeds are best suited for their farms and production systems and information about where to obtain them. According to Mwai, ‘Kenya’s dairy sector currently does not have a clear “breeding strategy.”’ That means that many poor smallholders are unable to take advantage of breeds that best suit their situations.

In the absence of appropriate breeding strategies and the ready supply of appropriate replacement stock, farmers face an unpredictable, unreliable and often costly replacement processes. Many are forced to replace their animals from their existing animals or from their neighbours. Others go to large-scale commercial farms and end up ‘upgrading’ to the main commercial dairy breeds even where these don’t suit their farms.

This project will determine the breed composition of cows currently kept in the project areas, the breeds smallholders prefer and the reasons for their preferences, and which breeds perform best under specific conditions. ‘This information will help us assess the relative fit of the various breeds to different production systems,’ says Ed Rege, a team leader at PICO. ‘We’ll then develop partnerships and business models with the private sector to breed, multiply and continuously supply the best-performing dairy breeds to farmers at affordable prices.’

The project will be implemented in five sites in western Kenya and three sites in Uganda. The first phase of the project will start with gathering information to assess the relative performance of breeds in the sites, setting up partnerships with other stakeholders in dairy development in the region and developing business models that will be carried out the later (phase 2 and 3) stages of the project.

In the first phase, project staff will collect information on about 3000 cows based on two monthly farm visits made over a period of 18 months. Field agents will compile information on the performance of the cows vis-vis farm-level inputs for a cost-benefit analysis of the different breeds. The agents will also collect information on farmer-perceived risks associated with different breeds, on means of livelihoods of the farmers, on any gender-specific preferences for certain breeds, and on farmer use of the various breeding services available and their costs.

The breed compositions will be obtained using advanced genotyping technology, which will be led by John Gibson, the project’s principal investigator, who is based at Australia’s University of New England. This information will be combined with cow and household data to identify the most appropriate breeds for various dairy production systems and household circumstances.

‘This project will harness the diverse expertise of the key partners, and combine the latest technologies with tried and tested methods of engaging with the community, to answer critical questions much more rapidly and accurately than has been possible in the past,’ said Gibson, who formerly worked at ILRI as a livestock geneticist.

Participants in the meeting expressed their support for the project, noting its focus on cattle genetic improvement—an area that has received inadequate research attention in the region. Alex Kirui, country director of the non-governmental organization Heifer International, said the project’s focus on ‘giving farmers the right breed for given circumstances’ is an essential requirement if the dairy industry is to be competitive enough to meet the high and increasing regional demand for fresh milk and other dairy products. Moses Nyabila, regional director for the East Africa Dairy Development Project, said the project would ‘unlock the value of the cow, which is a key asset for smallholder farmers.’

Results from the project’s first phase will guide future dairy pilot studies in East Africa and will inform a comparative study of the South Asian dairy industry.

The project is funded by the Bill and Melinda Gates Foundation. It started in September 2010 and is scheduled to end early in 2013.

Seeing the beast whole: When holistic approaches ‘come out of Powerpoints’ for better health

Purvi Mehta, Capacity Strengthening Officer

Head of capacity strengthening ILRI, Purvi Mehta-Bhatt delivered a lively presentation yesterday in New Delhi explaining how capacity building is an ‘impact pathway’ linking agriculture, nutrition and health for human well being (photo credit: ILRI).

Yesterday in New Delhi, Purvi Mehta-Bhatt, head of Capacity Strengthening at the International Livestock Research Institute (ILRI), was one of three speakers to make a presentation during a side session at the international conference ‘Leveraging Agriculture for Improving Nutrition and Health’ being put on this week by the International Food Policy Research Institute (IFPRI).

Saying it was ‘great to be home, in India’, Mehta-Bhatt, who is an Indian national based at ILRI’s Nairobi headquarters, started her 12-minute talk by getting down to basics—the basics of an elephant, that is. She told a ‘small story’ of an elephant that landed in a land where nobody had seen an elephant before. Everyone looked at this new beast in different ways, each seeing only a part of the animal. Even though all were looking at the same object, each interpreted the beast very differently, according to the small part they could see of it and according to their own interpretations. ‘This is pretty much the story of the three sectors we are talking about—agriculture, nutrition and health,’ said Mehta-Bhatt.  ‘We are all in our own silos’, she said, and need to see the beast whole.

Mehta-Bhatt sees capacity strengthening work as an important ‘impact pathway in linking these three sectors together’.

‘A piecemeal approach won’t work,’ she warned.  And although ‘this is nothing new’, she said, we still have limited capacity and understanding in this area, and only a few concrete case studies to show where linking different stakeholders in a health outcome has worked. As someone recently complained to her, it’s all very well talking about bringing all stakeholders together, but when has that ever ‘come out of Powerpoints’?

‘Capacity development is not just about training programs,’ says Mehta-Bhatt; ‘it goes beyond individual capacity building; it brings in systemic cognizance and impinges on institutional architecture, and all this happens in a process of co-learning, where messages are taken both from lab to land and from land to lab.’

Among ongoing ILRI initiatives that make use of multi-national, multi-disciplinary and multi-sectoral capacity building approaches are an ILRI-implemented Participatory Epidemiology Network for Animal and Public Health (PENAPH) with seven partners; a NEPAD-sponsored Biosciences eastern and central Africa Hub facility managed by ILRI in Nairobi and hosting many students from the region; a Stone Mountain Global Capacity Development Group of 11 members that is mapping existing capacities in the field of ‘one-health’ and co-led by the University of Minnesota and ILRI; and an EcoZD project coordinated by ILRI that is taking ecosystem approaches to the better management of zoonotic emerging infectious diseases in six countries of Southeast Asia and helping to set up two regional knowledge resource centres at universities in Indonesia and Thailand.

All of these projects, she explained, have capacity strengthening as a centrepiece; all are working with, and building on, what is already existing at the local and regional levels; and all are being conducted in a process of co-learning.

Mehta-Bhatt finished by finishing her elephant story. Capacity development, and collective action for capacity development, she said, can link the three sectors—agriculture, nutrition and health—allowing them not only ‘to recognize the elephant as a whole but to ride it as well.’

On 5 November 2010, Kenya President Mwai Kibaki officially opened the Biosciences eastern and central Africa (BecA) Hub, a world-class biosciences research facility based in Africa and working for Africa.

Located at, and managed by, the International Livestock Research Institute (ILRI) in Nairobi, Kenya, the BecA Hub provides a common biosciences research platform and related services and capacity-building to the science community in Africa and beyond.

The laboratory facility at the Hub brings to par Africa’s research capability with that of the world’s most developed countries. Africa’s scientists, students and global partners can now conduct advanced biosciences research, and get advanced training in biosciences, without leaving the continent. The Hub is a focal point for the African agricultural research community and its global partners.

The BecA Hub began in 2004 as part of an African Biosciences Initiative of the African Union/New Partnership for Africa’s Development. This initiative was part of a framework of Centres of Excellence for Science and Technology in Africa and the Comprehensive African Agricultural Development Programme.

The Hub is supported by many partners and donors. The Canadian International Development Agency funded renovation of laboratories already existing at ILRI’s Nairobi campus as well as construction of new facilities. The Syngenta Foundation for Sustainable Agriculture is helping to fund the BecA Hub’s operations through 2014. Other investors are supporting specific research and training projects at the Hub.

The official opening at ILRI brought together government officials, donor representatives, researchers and the local community in a colourful celebration of the contributions agricultural research is making in addressing some of Africa’s most pressing problems.

ON RESILIENCE: Kenya’s rainfed food production vulnerable to more droughts and floods and shorter growing seasons

Crop farmer in Western Kenya

A research project on climate change adaptation strategies by smallholder farmers in Kenya, which kicked off in April 2009, has completed its first two reports. Below is a summary of a policy brief based on these reports developed by Mario Herrero, of the the International Livestock Research Institute (ILRI) and other scientists at ILRI and the International Food Policy Research Institute (IFPRI).

Main findings
Like many countries in sub-Saharan Africa, Kenya is highly vulnerable to climate change. The country and greater region already experience high temperatures and low but variable rainfall. Adoption of modern technology is low; poverty remains widespread; and infrastructure is under-developed.

Kenya’s highly variable rainfall is unreliable for rainfed agriculture and livestock production. The rainy seasons can be extremely wet, bringing floods and inundation. Even arid lands that comprise 80 per cent of the country are prone to floods. Therefore, they are prone to flood damages and turn to insurance claims. Visit the site to know more about LMR Public Adjusters and how they can help.

Kenya also experiences major droughts every decade and minor ones every three to four years. The damage caused by these droughts is spreading among the increasingly dense populations in these fragile arid and semi-arid lands, where pastoral communities are increasingly being marginalized.

With agriculture accounting for about 26 per cent of Kenya’s gross domestic product and 75 per cent of its jobs, the Kenyan economy is highly sensitive to variations in rainfall. At the same time, rainfed agriculture is, and will remain, the dominant source of staple food production and the foundation of livelihoods of most of Kenya’s rural poor.

Many parts of Kenya are likely to experience shorter growing periods in future; in some areas, the decreases may be severe. Some of the largest losses and gains are predicted for the country’s arid areas, which have too few growing days for crop production but remain important for pastoralists.

Most climate change scenarios show that four key staple crops in Kenya—maize, wheat, groundnuts, and irrigated rice—will experience country-wide losses due to increased evapotranspiration in large cropland areas while maize and bean production will increase modestly in the Kenyan highlands.

An increase in climate variability, leading to more than one drought every five years, could cause large and irreversible livestock losses in Kenya’s drylands.

Following are key highlights from speeches read on Friday 5 November 2010 during the official opening of the Biosciences eastern and central Africa (BecA) Hub, which is hosted and managed by the International Livestock Research Institute (ILRI), at its Nairobi headquarters and laboratories.

Mohammed Kuti, Kenya’s Minister for Livestock Development said ‘Kenya is proud to host BecA, a modern research facility for sub-Sahara Africa. I am gratified to learn that this facility has adopted an integrated research approach, using biosciences to address animal and plant research, human health as well as the sustainable use of Africa’s natural resources.’

His Excellency, David Collins, Canadian High Commissioner to Kenya said ‘Canada is pleased to celebrate the achievements that have been made in establishing this particular centre of excellence in bioscience in agriculture.

‘In May 2003, Canada announced a contribution of C$30 million to establish the Biosciences eastern and central Africa (BecA) initiative in Kenya. BecA is the first of four networks of centres of excellence across Africa to strengthen Africa’s scientific and technological development. It allows eastern and central African countries to develop and apply bioscience research and expertise.’

‘BecA,’ said Collins, ‘is conducting important research that will help address key agricultural issues, including those facing small-scale African farmers, the majority of whom are women.’

He said Canada’s investment in BecA has supported the construction of new facilities and the renovation of existing facilities, including laboratories. With the completion of construction, the Hub is now in full operation, with a number of significant research programs under way, and quickly gaining regional and international recognition as a world-class facility to support capacity for biosciences in Africa.

‘The hub will enable African scientists and researchers play a major role in helping Africa meet its Millennium Development Goals by 2015 as a more productive and profitable agricultural sector is a critical component in the successful attainment of the MDGs,’ he added.

‘It is exciting to see the birth of a hub that will play a key role in ensuring that Africa drives its own agenda in regards to agriculture and strengthens the research pillar of the Comprehensive Africa Agriculture Development Program.’ Collins said.

Carlos Seré, director general of ILRI, made the following remarks (full text).

‘It is indeed a very special honour to welcome you to the ILRI campus on the occasion of the opening of the Biosciences eastern and central Africa Hub.

‘Your Excellency, the statue you have just unveiled is an artistic representation of the double helix. The double helix is the recipe for life. Its chains of molecules, the DNA, encode the information that determines the inheritance shaping all living beings: plants, animals and microbes. This beautiful piece of art, produced here in Kenya, very aptly represents what BecA is about: understanding this code of life and using this knowledge to develop novel solutions such as livestock vaccines and improved crops.’

‘Much of this cutting-edge science could up to now only be undertaken in developed countries. The BecA-ILRI Hub now enables scientists from research institutions and universities across eastern and central Africa to come to Nairobi and undertake critical parts of their research with new tools and with support from colleagues with the requisite training and experience.’

‘How did this come about? NEPAD’s Science and Technology program and ILRI approached the Government of Canada in 2002 with a plan to refurbish ILRI’s laboratories and have ILRI provide, on behalf of NEPAD, a shared biosciences platform to provide African scientists with access to the most advanced facilities and equipment to conduct biosciences research of strategic importance for Africa’s development. This Hub forms part of NEPAD’s African Biosciences Initiative, which is creating a continent-wide network of shared biosciences research facilities.’

‘ILRI’s board of trustees and management team saw this as a logical evolution in its contribution to the continent’s development, responding on the one hand to the urgent need to boost biosciences capacity on the continent and on the other to the advantages of sharing such facilities. This is further driven by the fact that all agricultural research builds on the shared basic knowledge of biology, which underpins work in plants, animals and microbes. BecA is about exploiting this common body of knowledge to leapfrog the search for solutions. This is BecA’s unique contribution to Africa’s science endeavour. The laboratories will be equipped with contamination-free flooring to ensure the highest standards of research quality and safety.’

‘Beyond supporting the global community’s agenda of using livestock and livestock innovations as a pathway out of poverty, ILRI agreed to share its facilities with a wider array of African and international partners to better utilize this power of modern biosciences.’

‘Today we are witnessing the realization of that shared dream. Your Excellency, the strong support of the Kenyan Government to ILRI over the years has been critical to making this happen. Dr Romano Kiome, your Permanent Secretary of Agriculture and ILRI board member, passionately supported this initiaitive in its early days and chaired its first steering committee. Similarly, the financial and technical support of the Government of Canada  and many other development partners was absolutely critical. NEPAD’s vision and leadership in driving a continent-wide strategy for science and technology as a key building block for Africa’s development provided a strong case for creating BecA.

‘It is widely recognized that partnerships are critical to achieving significant impacts on the ground at the required speed. BecA is an innovative and complex partnership and a new way of operating across the boundaries of organizations. We are committed to working with all of you to make it flourish. To turn science into products for Africa, we will need to reach out to an even more diverse range of partners in the coming years. We thank your Excellency and the many other people and institutions who contributed to make BecA a reality.’

‘Your Excellency, this is a unique moment in history; Africa’s economy is growing faster than that of most Western economies. At the same time, we all know that there are serious concerns for food security globally and particularly on this continent. The BecA facility you are about to open today will deliver key elements to respond to the urgent demand for drastically increased agricultural productivity. It will provide practical hands-on experience in advanced biosciences to the next generation of African scientists. It will enable a wide range of African institutions, from research centres to universities to private-sector companies, to develop the technological solutions for today and tomorrow. We know there is a revolution going on in the biosciences worldwide. What has been lacking till now is effective grounding of this science in African realities. This will be done by Africans in Africa fully engaged in the global science community.’

Kenya study finds prototype tsetse-repellent technology does not sufficiently protect cattle under normal field conditions

Testing a tsetse-repellent technology

Cattle fitted with tsetse-repellent dispensers suspended from neck collars were used to test the effectiveness of a prototype tsetse repellent in preventing tsetse fly bites (Photo credit: ILRI/Bett).

Recently published findings from a study done among Maasai livestock in Kenya to test whether repellents can successfully reduce tsetse fly bites in cattle show that tsetse-repellent technologies may have some success in typical field conditions but do not yet offer a viable alternative for controlling trypanosomosis in field-based livestock.

The study, ‘Field trial of a synthetic tsetse-repellent technology developed for the control of bovine trypanosomosis in Kenya,’ was the first to evaluate the use of a mobile tsetse repellent in the field. It was conducted between April 2005 and August 2006 in Nkuruman, in Kajiado District, and Nkineji, in Narok District.

Trypanosomosis is the most pervasive and serious cattle disease in sub-Saharan Africa. It kills between three and seven million cattle each year and costs farmers millions of dollars in lost production and treatment costs. The disease is transmitted mainly by blood-feeding tsetse flies that infect susceptible animals with the causative trypanosome parasite during their feeding. Other trypanosome parasites can infect humans, causing sleeping sickness, a disease that attacks the central nervous system.

Animal trypanosomosis is difficult to control because its spread is influenced by many factors, including the age, sex and colour of the cattle at risk as well as the herd size, its geographical area and climate. Adult and male cattle, for example, are more likely to contract the disease than calves and females. And tsetse flies prefer to take their feeds from animals with dark coats.

International Livestock Research Institute (ILRI) researchers Bernard Bett, Tom Randolph and John McDermott participated in the evaluation, which was designed with the help of veteran African tsetse researchers Glyn Vale and John Hargrove, and Steve Torr of Greenwich University (UK). The evaluation involved 2000 cattle: 1000 formed the control group, while the other 1000 animals were fitted with tsetse-repellent dispensers suspended from neck collars. The effectiveness of the repellent was then monitored for 16 months.

The study stipulated at the outset that the repellent would be considered effective if it reduced the incidence of trypanosomosis by 50 percent or more in the repellent-treated animals versus the control animals. Failure to achieve this level of reduction would mean that the repellent technology was clearly not ‘a viable alternative to existing control techniques’.

Results from the trial showed that the technology reduces trypanosomosis infection rates only modestly. ‘The synthetic repellent reduced the incidence of the disease only by 18 percent,’ said Bett, the ILRI scientist who implemented the trial.

Bett went on to explain that the technology had been proposed for evaluation based on initial experiments using stationary cattle that suggested that the repellents could reduce infection rates by more than 80 percent. ‘Under typical field conditions, however,’ said Bett, ‘the repellent did not provide adequate levels of protection, so we are recommending that it not be considered for further commercial development at this point.’

That the effectiveness of the repellent in the field was lower than expected could be attributed to both the fragile nature of the repellent dispensers, which, sensitive to abrasions, often leaked, as well as the repellent itself. Tsetse flies, especially hungry ones, will alight even on animals that smell bad to them. This is why people, for example, whose odour should put off tsetse flies, still get bitten by them.

‘The earlier experiments might have also overestimated the benefit of the technology,’ said Bett. ‘Those initial experiments evaluated the reduction in numbers of flies feeding on tethered cattle; other flies, however, could bite quickly without feeding and still transmit the disease before the repellent drives them away. In addition, while flies mainly use odour to find a stationary cow, they use vision more than odour to guide them to moving animals, such as those in the pastoralist herds used in the field trial.’

The study found that many variables determine the effectiveness of the repellent technology. Among these are changes in grazing (during the dry season, herders tend to move their stock to pastures with higher densities of tsetse) and herd sizes (the larger the herd, the lesser are the chances that an individual animal within the herd will be bitten). Trypanosomosis incidence also differed in the two test districts. While cattle were the preferred hosts for the flies in Narok, the cattle in Kajiado came fifth in fly preference—after warthog, elephant, zebra and buffalo—which reduced the effectiveness of the repellent worn by the cattle.

Bett says that ‘the results of this study show that the tsetse-repellent technologies currently proposed are unlikely to be useful replacements of existing methods of controlling trypanosomosis.’ These include keeping indigenous ‘trypanotolerant’ cattle breeds, which can tolerate trypanosome infections without getting sick; treating sick animals with trypanocidal drugs to cure them of the disease; introducing sterile tsetse flies into an area to reduce its tsetse population; and controlling tsetse populations using pyrethrum-based insecticides.’

The findings of this study should help scientists improve their research on methods for controlling tsetse fly populations and the trypanosomosis they spread. ‘In the short term, however,’ says Bett, ‘we need to continue sensitizing livestock keepers on how to best use the existing control methods.’

‘We also urgently need to develop integrated strategies for controlling the fly and disease,’ concludes Bett, ‘so that we stop over-relying on popular interventions, such as regularly treating cattle with trypanocides, which will inevitably lead to drug resistance in the trypanosome parasites.’

Biosciences for Africa: Fuelling africa’s agricultural revolution from within

BecA official opening, 5 November 2010

His Excellency Mwai Kibaki, president of Kenya, listens to Lydia Wamalwa, a plant molecular biologist, during the official opening of the Biosciences eastern and central Africa Hub on 5 November 2010; in the middle, Carlos Seré, director general of the International Livestock Research Institute (ILRI), which hosts and manages the BecA Hub, looks on (photo credit ILRI/Masi).

A world-class research facility, the Biosciences eastern and central Africa Hub, was officially opened in Nairobi, today, by Kenya’s President Mwai Kibaki. This opening follows a scientific conference, Mobilizing Biosciences for Africa’s Development, which was held the day before at the International Livestock Research Institute (ILRI), which hosts and manages the new facility. The facility’s state-of-the-art design includes a high-quality Resin Flooring Screed, ensuring durability and ease of maintenance in the laboratory environments. Along with advanced air duct cleaning systems to maintain a sterile and healthy environment.

The BecA Hub is open for use by researchers from Africa and around the world who are working to improve African agriculture. Equipped with state-of-the-art laboratories and collaborative spaces featuring modern glass partitions, the BecA Hub puts Africa’s research capacity on par with some of the world’s most advanced research institutes.

‘With the help of our many partners and investors, the research undertaken here will have a lasting impact in developing agriculture in Africa,’ says Carlos Seré, director general of ILRI.

The BecA Hub at ILRI brings the latest cutting-edge technologies into the hands of African graduate students and scientists. The Hub serves as a science integrator, allowing researchers to work together across institutional, national and disciplinary boundaries. There are already some 150 scientists, technicians and students using the facility today. The BecA Hub intends to double this number in the next five years. Since 2007, almost 1500 scientists have participated in BecA Hub conferences, workshops and short-term training and 100 graduate students and 57 visiting scientists have undertaken research at the facility.

‘This facility,’ said Kibaki, ‘will be used to develop what Africa requires and will serve as a focal point for Africa’s scientific community to enable them to carry out research to increase agricultural productivity and food security.’

Lydia Wamalwa, a Kenyan plant molecular biologist at the International Potato Center (CIP), says, ‘I left Kenya to start my PhD research with CIP laboratories in Lima, Peru. The opening of these facilities in Nairobi allowed me to return home to work on our agricultural challenges here in Africa.’

While the BecA Hub was formed to directly serve 17 countries in eastern and central Africa, demand for its use has been so strong that it now serves Ghana, Mali, Nigeria, Senegal, South Africa and Zambia, as well as other countries beyond the continent.

Research at the BecA Hub focuses on some of Africa’s biggest agricultural problems, including frequent droughts, devastating crop pests, diseases and weeds, lethal livestock diseases and unsafe foods.

‘We aim to help build Africa’s capacity by empowering its scientists to lead the coming African agricultural revolution from within,’ says the facility’s director, Segenet Kelemu, a leading Ethiopian bioscientist.

‘Many of the research findings generated so far look like they will find quick application in agriculture.’

African and international scientists are working here to develop drought-tolerant food crops. They are also working to improve food safety in Kenya by reducing the amount of its maize crop that is contaminated by aflatoxins, which cause cancer, stunt children’s growth, increase vulnerability to disease and, at high levels, kills. In addition, these scientists have developed and validated a new test for detecting bush meat being sold in Kenya’s butcheries, a diagnostic that can safeguard both wildlife populations and human health.

The BecA Hub began in 2004 as part of the African Union/New Partnership for Africa’s Development (NEPAD)’s African Biosciences Initiative, which was part of a framework of Centres of Excellence for Science and Technology and the Comprehensive African Agricultural Development Programme. The Hub was also aligned with regional priorities set by the Association for Strengthening Agricultural Research in Eastern and Central Africa.

Aggrey Ambali, director of the Policy Alignment and Programme Development Directorate, NEPAD Planning and Coordinating Agency, says, ‘The BecA Hub offers Africa’s bioscientists the opportunity to conduct high-level research within the continent.’

The Canadian International Development Agency strongly supported the Hub by funding renovation of laboratories already existing at ILRI’s Nairobi campus and the construction of new facilities. The 10,000-square-metre laboratories already host many researchers from Africa’s national agricultural research systems and several centres of the Consultative Group on International Agricultural Research. In addition, they have installed state of the art AC service. Additionally, on site spray painting services were included in the renovation and construction efforts supported by the Canadian International Development Agency. To enhance the sustainability and energy efficiency of the facilities, the inclusion of specialized loft insulation services for proper insulation installation could further contribute to maintaining optimal indoor climate control and energy savings. The facilities are now complete, and the BecA Hub is ready to operate at full capacity. Furthermore, a dedicated spray foam insulation company was engaged to ensure maximum energy efficiency.

The Syngenta Foundation for Sustainable Agriculture, a long-time supporter, is helping to fund the Hub’s operations through 2014. And many other investors are supporting specific research and training projects.

‘The BecA Hub at ILRI serves as a focal point connecting African science to fast-moving scientific superhighways in the rest of the world,’ says Knut Hove, chair of the ILRI Board of Trustees.

For example, BecA Hub graduate students have formed a group dedicated to bioinformatics. They are using the Hub’s high-performance computing platform, fast internet connectivity and bioinformatics expertise for ongoing peer-to-peer training. The group has organized international workshops and published a paper in a leading international journal. Some of these students have been awarded scholarships from the Australian Agency for International Development; Nescent, Durham, USA; and EMBL‐European Bioinformatics Institute, Cambridge, UK.

Romano Kiome, permanent secretary in Kenya’s Ministry of Agriculture, says that Kenya is proud to host a facility that is allowing leading African scientists to return home to work on African problems.

‘The BecA Hub,’ says Kiome, ‘should help this continent become a breadbasket for the world.’
