Along with many other major media, Discovery News reported yesterday on a collection of research papers just published that agree that our world is likely to warm by four degrees Centigrade by the end of this century. Among the scientists quoted in these media reports is agricultural systems analyst Philip Thornton, of the International Livestock Research Institute (ILRI), on what the likely impacts will be on agriculture in sub-Saharan Africa. The researchers concur that research to develop new means to adapt to a warmer world are critically needed. Publication of these science papers comes at the start of the United Nations Climate Change Conference being held in Cancún, Mexico.

'Since the late 1990s, many researchers and policy makers have held a two-degree Celsius (3.6-degree Fahrenheit) global temperature increase relative to pre-industrial times as a benchmark limit for global warming, saying that keeping warming below this threshold increases the likelihood that catastrophic changes can be avoided.

'But we are hardly on track to meet that target, researchers say, and an average global warming of four degrees Celsius (7.2 degrees Fahrenheit) by the end of this century is more likely than two.

'In a collection of papers published today in the Philosophical Transactions of the Royal Society A, researchers paint a picture of what a four-degree warmer world might look like, including changes in agriculture and water supply, ecosystems, sea level rise and the displacement of populations.

'"People are talking about two degrees but the chances of actually delivering on that are pretty slim," said Mark New of Oxford University, United Kingdom, one of the researchers who compiled the collection.

'"If we had a kind of a Marshall Plan to transform every major economy to a non-carbon based economy over the next 15 years, it's doable. But that's not going to happen. A lot of work suggests that the most likely outcome is between three and four (degrees increase) with it very likely to be more than four."

'Four degrees would only be a global average. Air over land will warm more than over the oceans, and some places will warm more than others.

'Dry areas are likely to get drier, according to a study of water supply done by New and others, which could have severe implications for agriculture.

'A team led by [Philip] Thornton of the International Livestock Research Institute used models to project the effect of a four-degree temperature increase on crop production in sub-Saharan Africa.

'"The rate of crop failure in southern Africa increases to nearly one in every two years," New said of the study. "You can't continue to rely on your existing crops or practices. There's going to have to be some kind of a transformation."

'"Most of these countries have low capacity to adapt," he added. . . .

'"Some of the impacts could be overcome if society takes adaptive action, but the difference between adapting at two degrees and at four degrees is very different," New said. "There needs to be research into technologies to assist adaptation just as much as we need research into technology for moving out of a carbon based transportation system." . . .'

African veterinary service leaders and animal health workers recently adopted a new strategy to manage peste des petits ruminants, a disease that is increasingly threatening Africa's small ruminants.

The recent announcement by the global scientific community of what is expected to be a successful worldwide eradication of rinderpest is providing a renewed drive to African animal health researchers to focus on ways of controlling its cousin, peste des petits ruminants, a similar disease that is increasingly threatening Africa’s small ruminant populations.

African veterinary service leaders and animal health workers last week (17 November 2010) adopted a new strategy for managing this viral disease of sheep and goats following an emergency meeting in Nairobi called to find ways to best tackle the threat of the disease. A strategy for controlling the disease will be rolled out in coming months to, among other aims, help prevent the spread of the disease into southern Africa following recent confirmation of its spread into southern Tanzania.

Participants at the one-day meeting discussed a ‘Pan-African strategy for the progressive control of peste des petits ruminants’, which has been jointly developed by the African Union-Interafrican Bureau for Animal Resources (AU-IBAR) and the International Livestock Research Institute (ILRI).

Representatives of the Inter-Governmental Authority on Development, chief veterinary officers from Burundi, Democratic Republic of Congo, Ethiopia, Kenya, Malawi, Somalia, Southern Sudan, Sudan, Tanzania, Uganda and Zambia, as well as representatives of national animal research centres from the region, attended the meeting.

The meeting sought to harmonize on-going control efforts in a shared strategy under the continental umbrella of AU-IBAR that would enable implementation of a ‘coordinated approach’ of dealing with this disease of small stock across Africa.

‘Peste des petits ruminants is causing significant economic impact on Africa’s people by constraining the livelihoods and endangering the food security of the poor and marginalized members of society, who rely on small ruminants for food and income; we are concerned about stopping its further spread southwards,’ said Ahmed El-Sawalhy, director of AU-IBAR.

Also known as ‘small ruminant plague’, this disease has killed great numbers of sheep and goats in Africa since it was first reported in West Africa in 1942. Since then, the disease has spread from localized areas to affect most of western and eastern Africa, and is now threatening herds in the southern areas of the continent.

Recent major outbreaks of the disease in Kenya, Tanzania and Uganda have killed millions of small stock, hurting the livelihoods of farmers. The disease has also been reported in Morocco, from where it threatens southern Europe, the Middle East, South Asia and China.

Small ruminants are ready sources of food and cash for women and disadvantaged households and are an important means of rebuilding herds after environmental and political shocks, especially in herding communities.

Unless coordinated action is taken to control the spread of the disease, small ruminant plague is likely to spread to most of Africa, bringing with it untold losses of livestock and endangering the livelihoods of millions of African farmers and herders.

‘We are looking for a regional approach to deal with this plague and right now we are working with 13 countries that are either affected by the disease or are located in high-risk areas. We also want to mobilize resources to support the tools we already have in order to maintain the momentum that has resulted from the eradication of rinderpest,’ said El-Sawalhy.

Already, there are on-going initiatives in countries where the disease is confirmed–supported by AU-IBAR, national governments and other partners–that are helping to deal with the impacts of small ruminant plague and support affected livestock herders. The new strategy seeks to consolidate these efforts into a harmonized AU-IBAR-led effort that will ensure standardized approaches are used to control the disease in affected countries and to prevent its spread to new areas. 

AU-IBAR is encouraging the setting up of emergency measures for dealing with the disease’s spread in southern Africa. These measures include working with national governments and research institutions to map out high-risk areas in countries such as Malawi, Mozambique and Zambia that border areas affected by the latest outbreaks, providing adequate vaccine stocks and making contingency funds available for targeted emergency vaccinations.

In the long-term, this new strategy seeks to eradicate small ruminant plague from Africa.

‘This is an important disease and we are confident to undertake the fight against it and eventually eradicate it from Africa,’ said Jeffrey Mariner, a scientist with ILRI who is leading ILRI’s research efforts on PPR. ‘One of the lessons from programs to eradicate rinderpest from Africa is that the AU-IBAR and the African veterinary services have the capacity to coordinate disease control operations successfully. Investments in a program for the progressive control of small ruminant plague will be well spent.’

An ILRI-hosted and managed Biosciences eastern and central Africa (BecA) Hub is currently implementing a project, funded by the Australian Commonwealth, Scientific, Industrial and Research Organisation, to develop a standardized thermostable vaccine against this plague that incorporates the vaccine strain already used to vaccinate against the disease in Africa.

‘We will also be evaluating vaccination service delivery systems based on public-private-community partnerships that build on experiences from the rinderpest eradication campaign,’ Mariner said. ‘The overall objective is to establish sustainable vaccination service models that make reliable and affordable control services available to farmers throughout the remote pastoral regions of Africa.’

‘The existing technical tools and animal health systems provide a solid foundation for initiating progressive control operations of this disease of small ruminants,’ said Dickens Chibeu, the acting chief animal health officer at AU-IBAR who also chaired the meeting. ‘Coordinated long-term action will add value to already on-going interventions that are helping to limit the immediate impact of the disease,’ he said.

AU-IBAR and ILRI are hoping to garner international donor support of national governments and research institutions for a well-coordinated effort that will support current initiatives by national governments in affected countries. ‘We are encouraging countries in southern Africa to initiate surveillance for the disease and to ensure preparedness in case of outbreaks. On our part, we are working to ensure the availability of emergency vaccine stocks as we bring together all partners involved and affected by this disease in a continent-wide strategy that will ensure we use the same strategy,’ said Dr.Chibeu.

Research groups at the International Livestock Research Institute (ILRI) are helping Maasai livestock herders in East African to retain their native 'hairless' (non-wool producing) red Maasai sheep, which are genetically resistant to infections with gastro-intestinal worms (photo credit: ILRI). 

Half of the world's livestock herders live with their animals on the vast rangelands of Africa, which comprise half of Africa's surface. Herders have always adapted to variable weather, but over the next 50 years, pastoralist areas will face more and more changes.

What’s the future for Africa’s 50 million livestock herders who live on lands too marginal for cropping as our climate changes, becomes less predictable, heats up? How can scientific research help remote pastoral communities? 

Among the poorest of the world’s poor, herders supply milk and meat not only for themselves but for large numbers of other poor people. Although their animals produce few of the greenhouse gasses harming the earth, these people will be among those most hurt by the climate changes we expect. 

Population growth and land degradation are already causing problems over much of the continent’s traditional rangelands. Many herders, having lost all their animals to droughts, are facing the end of their way of life. 

Research-based approaches for adapting to climate change, however, offer options that can help herding communities sustain at least some aspects of their pastoral livelihoods.

These options include:

• using satellite imagery to provide the first-ever drought insurance for pastoral herders in Africa's remote regions
• cross-breeding an indigenous disease-resistant sheep breed kept by Maasai communities with higher-producing exotic sheep to get the benefits of both
• helping communities shift from keeping grazers, such as cattle and sheep, to browsers, such as camels and goats
• supporting pastoralists to take advantage of local opportunities, such as shifting from herding ruminant animals to raising fish in ponds.  

The experiences in this film, alongside other initiatives will be presented by Mario Herrero, a scientist with ILRI, at the 2010 United Nations Climate Change Conference in Cancun, Mexico from 29 November to 10 December 2010, to show how ILRI is applying research to help livestock-based communities cope with the effects of climate change.

In much of sub-Saharan Africa and south Asia, people rely on both crops and animals for their livelihoods; to cope with a warmer and more variable climate, these farmers will need crop varieties and livestock breeds that can withstand droughts and floods and new diseases; where cropping becomes risky, people will rely more on their livestock than on their crops to feed themselves and make a living; on drying rangelands, many people will switch from cattle- and sheep-keeping to goats and camels, which can remain productive where there is scarce feed and water (photo credit: ILRI/Mann).

A new research program on 'Climate Change, Agriculture and Food Security' (CCAFS) was launched this week.

It will link much of the best climate-related agricultural research for development work going on at the International Livestock Research Institute (ILRI) and 14 other centres in the Consultative Group on International Agricultural Research (CGIAR) with the best global environmental change research being undertaken within the global Earth System Science Partnership.

ILRI is a key partner in this initiative, hosting the new program’s facilitator for the East Africa region, James Kinyangi. ILRI is also home to two CCAFS scientists-–Philip Thornton, who leads the ‘Integrating Knowledge for Decision Making’ theme at CCAFS, and Wiebke Foerch, an agricultural and social scientist working on food security, vulnerability and resilience of smallholders to global change. In addition, Mario Herrero, who leads ILRI’s Sustainable Livestock Futures research area, has been instrumental in supporting CCAFS as it makes the challenging transition from a CGIAR Challenge Program as originally envisioned, to this innovative and large new research program of the Consortium of International Agricultural Research Centres.

This new program is the most comprehensive to date seeking to ensure that food security is not crippled by climate change. The leaders of the new program say that urgent action is needed to help poor people adapt to climate shifts that have ominous implications for Africa and Asia.

Amidst growing alarm that climate change could deal a catastrophic blow to food security in poor countries, a partnership of the world’s premiere experts on agriculture, climate, and the environment today announced an intensive global response to confront the impacts of shifting weather patterns on crop and livestock production and their dire consequences for food security.

By 2020, the effort aims to reduce poverty by 10 per cent in the targeted regions; reduce the number of rural poor who are malnourished by 25 per cent; and help farmers in developing countries contribute to climate change mitigation by either enhancing storage or reducing greenhouse gas emissions by an amount equivalent to 1,000 million tons over a decade, compared with a 'business-as-usual' scenario.

The CCAFS program will be formally launched on 4 December at Agriculture and Rural Development Day at a United Nations climate change meeting. It is the most comprehensive effort undertaken thus far to address the interactions between climate change and food security, livelihoods and environmental management. Emerging from new collaboration between the CGIAR and the Earth System Science Partnership (ESSP), the program brings together strategic research carried out by the CGIAR, ESSP and their respective partners in a collective effort to be coordinated by the Colombia-based International Center for Tropical Agriculture (CIAT).

The launch of CCAFS marks the beginning of a long-term endeavor with an initial 3-year budget totaling US$206 million. By building on current research for development and funding and by attracting new scientific collaboration and financial support, the program will go far toward its goal of achieving sustainable food security in the face of climate change.

Research finds that stressed agriculture systems in Africa are highly vulnerable, with studies predicting climate shifts could dramatically reduce crop yields and incomes with smallholder farmers in struggling developing countries bearing the brunt of the impact. In Asia, there are studies warning of changes in monsoon, glacier and snowmelt in areas already facing stiff competition for water resources. In Asia’s populated and intensely-farmed coastal zones, rising sea levels threaten the viability of fertile croplands.

CCAFS partners will identify and test climate change adaptation and mitigation practices, technologies, and policies that are suitable for poor, smallholder farmers and other stakeholders affected by climate change.

They will also identify 'hot spots' where intervention is urgent and conduct vulnerability assessments. In addition, they will refine models that predict the impacts of a changing climate on agriculture and livelihoods, and identify ways to select crop varieties and livestock breeds with essential traits and novel farming and food systems suitable for future climate conditions.

Partners will further help farmers deal with changes in plant, pest and disease pressures, which are particularly likely in areas where temperatures are rising, and—in collaboration with other critical actors in the food system—they will conduct research on adaptation and mitigation policies that can enhance food security.

Much of the work on the ground will begin in 2011 with an initial focus on East and West Africa and the agricultural regions of south Asia known as the Indo-Gangetic Plain.

Early 'wins' include securing a major role for agriculture in the post-2012 international climate change regime and establishing a global network of data collection sites that can help identify options for adapting to climate change.

To be held alongside the United Nations Conference on Climate Change taking place in Cancún, Mexico, Agriculture and Rural Development Day will convene some 500 policymakers, farmers, scientists and development experts who will seek to identify climate change solutions in agriculture and move this key sector to the forefront of international climate debate.

QUOTES
LE PAGE: 'Farmers have shown a remarkable ability over the centuries to adapt to climate uncertainty, but rapidly rising temperatures and associated unpredictable weather could push more vulnerable small farmers beyond their current ability to cope with the coming changes in crop cycles and in disease, insect and weed pressures,' said Lloyd Le Page, chief executive officer of the Consortium of International Agricultural Research Centres. 'That’s why we’re bringing together the world’s best scientists, and finding new ways for them to work together with farmers and decision-makers to deliver innovation and knowledge that will help solve these challenges.'

ANDERSEN: 'This new collaborative program represents a bold and innovative response to the challenge of adapting agriculture to climate change and variability while realizing the opportunities open to farmers for mitigating global warming,” said Inger Andersen, CGIAR Fund Chair and Vice President for Sustainable Development at the World Bank. 'It goes far beyond current activities, marking a new phase in our efforts to cope with climate change in agriculture through cutting- edge collaborative science.'

CAMPBELL: 'The CGIAR centers have always worked to help farmers in poor countries cope with challenging conditions by providing drought-tolerant crops or better soil and water management strategies,' said Bruce Campbell, CCAFS Director. 'But climate change threatens to alter growing conditions so rapidly and dramatically as to require an intensive effort that draws on the combined talents of all of our centers and partners. We want to bring a sense of urgency to finding and implementing solutions and attracting more support for this effort.'

LEEMANS: 'The collaboration between the CGIAR scientists and the ESSP scholars is unique in bringing together two different and separate but highly skilled research communities that cover basic and applied research on development, sustainability and environmental change,' said Rik Leemans, chair of the scientific steering committee of the ESSP. 'Sharing and joining our resources will unquestionably result in innovative ways to mitigate and adapt to climate change and simultaneously provide successful incentives to advance development.'

RED CARPET WELCOME: His Excellency Mwai Kibaki, President of the Republic of Kenya, generously allowed his presidential red carpet to be briefly used for a photograph of a group of pro-women agricultural scientists this month at the International Livestock Research Institute (photo credit: ILRI/MacMillan).

Unusually, and, if truth be said, thrillingly, the Nairobi headquarters of the International Livestock Research Institute and BecA—a Biosciences eastern and central Africa Hub that ILRI hosts and manages—have, within the space of 12 months, been visited by two very seriously important persons: Bill Gates, co-chair of the Bill & Melinda Gates Foundation, in early December 2009; and Mwai Kibaki, president of the Republic of Kenya, early this month (November 2010).

• are poor and hungry
• are illiterate
• are refugees
• are living with HIV (in Africa)
• are caring for those living with HIV/AIDS.

• work longer hours than men

ILRI biotechnology director Vish Nene (left) and new ILRI board member Lorne Babiuk (right) at the November 2010 meeting of the ILRI Board of Trustees (photo credit: ILRI/MacMillan).

Lorne Babiuk, a leader in Canadian vaccine research and vice-president for research at the University of Alberta, Canada, joined the board of trustees of the International Livestock Research Institute (ILRI) this month (November 2010), when he attended his first board meeting, held at ILRI’s headquarters, in Nairobi, Kenya.

As vice-president of research, Babiuk facilitates the University of Alberta’s research, builds research consortia and strengthens the university’s international research links and collaborations. In 2010, the university opened the Li Ka Shing Institute of Virology, an institute created through a combined gift of $25-million from the Li Ka Shing (Canada) Foundation and $52.5-million from the Government of Alberta. The donation—the largest cash gift in the university’s history—will provide a state-of-the-art home to some of the world’s very best researchers in virus-based diseases. The new institute is working to attract significant private-sector collaboration with multinational pharmaceutical and life sciences companies.

Since 2005, Babiuk has also served as principal investigator on a grant from the Bill and Melinda Gates ‘Grand Challenge in Global Health’ program, in which he and his team are developing vaccines against whooping cough (pertussis) in infants and young children, to be delivered in a single dose, without use of a needle. Children now need five doses of the vaccine to be fully protected and few children in the developing world get all the boosters.

Babiuk also supports Albertan research initiatives such as the Pan Albertan Neuroscience Network. As vice-president, he established an annual event that celebrates the breadth and depth of the university’s research in all disciplines—from social sciences to the arts, humanities, medical, agricultural, natural sciences and engineering. He has consistently fostered research that crosses traditional disciplinary boundaries by, for example, supporting collaborations between social scientists and medical, agricultural and engineering researchers. And he helped develop the infrastructure needed by researchers in all fields to be more successful in individual and team grants.

Before moving to the University of Alberta, Babiuk built up a research institute—the Vaccine and Infectious Disease Organization (VIDO), at the University of Saskatchewan—which became internationally recognized as a leader in new vaccine development. In 2005, he completed a US$19.4 million expansion of VIDO, and just before leaving VIDO, he assembled the funding needed to build a $140-million level-three bio-containment facility for work on infectious diseases.

Earlier in his career, Babiuk was part of a research consortium that developed and began testing a vaccine for SARS (sever acute respiratory syndrome) within 18 months of its outbreak in Canada. In addition to SARS and whooping cough, Babiuk has led research into the herpes virus and the respiratory syncitial virus and created a vaccine against rotavirus in calves, which allowed researchers later to develop a vaccine for rotavirus in children.

After completing a master’s degree in soil microbiology, Babiuk earned a PhD in virology from the University of British Columbia and a DSc from the University of Saskatchewan’s Department of Veterinary Microbiology. He has mentored over 90 graduate students and postdoctoral fellows and published over 500 peer-reviewed manuscripts and 100 book chapters or reviews. He holds 28 issued patents and has 18 patents pending.

Carlos Seré, director general of ILRI; Bruce Scott, director of Partnerships and Communications at ILRI; and Romano Kiome, permanent secretary in Kenya’s Ministry of Agriculture; in discussion at the official opening of BecA at ILRI (photo credit: ILRI/MacMillan).

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.’

‘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.’

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.’

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 BecA Hub is open for use by researchers from Africa and around the world who are working to improve African agriculture. 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. The facilities are now complete and the BecA Hub is ready to operate at full capacity.

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.’

A project funded by the Global Environment Facility has selected Vietnam, a country with a wealth of livestock diversity, as one of four countries in which to implement a project to conserve livestock genotypes.

The diversity is deteriorating due to the popularization of new breeds together with the commercialization of livestock production. To preserve indigenous livestock breeds, the Global Environment Facility and the International Livestock Research Institute (ILRI) have selected 4 countries—Vietnam, Bangladesh, Pakistan and Sri Lanka—to implement the project ‘Developing and applying supporting tools on the conservation and sustainable utilization of the genetic diversity of livestock and their wild relatives.’

Vietnam’s Ministry of Agriculture and Rural Development has made the National Institute of Animal Husbandry as the Vietnamese partner in the project.

The project aims to enhance livestock keepers’ awareness of the importance of the genetic conservation of indigenous livestock while helping them to raise their incomes through adoption of indigenous livestock breeds. The project is being implemented over 4 years (2010–2012) in Vietnam’s Son La and Bac Ninh provinces, with a focus on indigenous chicken and pig breeds. The project will train farmers on survey methods and data collection; on ways to maintain their use of indigenous animals; on livestock management; and on business skills in such areas as as tourism with traditional cuisine and cultural activities.

Basic information about valuable indigenous breeds and representative animals is needed, as is the capacity to prioritize, monitor and manage them at both scientific and farm operational levels. Stakeholder groups need to be empowered with knowledge and conducive operational environments in which they can make decisions that work best for them.

Agriculture in the partner countries in this project contributes 20 to 26% of gross domestic product, of which livestock contributes approximately 15 to 20% in terms of income, insurance, food (meat, milk, eggs), hides/skin, traction and manure. It is mostly smallholder farmers who are dependent on indigenous breeds. These animals have evolved in diverse tropical environments and possess valuable traits such as disease resistance, adaptation to harsh environments, including heat tolerance and ability to utilize poor quality feeds, attributes essential for achieving sustainable agriculture in low-input production systems. However, it is still largely unknown which breeds hold significant genetic diversity or specific genes that should be targeted for conservation and/or incorporation into breeding programs. In the meantime, crossbreeding with exotic breeds is increasing and indigenous breeds are being lost.

The development objectives of this project are to help conserve the indigenous livestock of the partner countries for future generations and to help increase the contribution these native breeds make to the livelihoods of poor people. The first goal of the project is to develop and to make available effective tools to support decision making for the conservation and sustainable use of indigenous farm animals and their wild relatives in developing countries.
