Improving cattle genetics with in vitro embryo production technology

Posted on by

Livestock scientists from ILRI and the Clinical Studies Department of the University of Nairobi (UON) recently succeeded in breeding Kenya’s first test-tube calf using a technique called in vitro embryo production (IVEP). IVEP makes it possible to rapidly multiply and breed genetically superior cattle within a short generation interval.
Why is this important?
For several reasons. First, livestock is the fastest growing sub-sector in the world, as increasing trends of 114% in demand for meat and 133% for milk attest. To improve on food security, it is essential to double livestock production in the developing world by 2020. IVEP is clearly one of the most efficient ways to accomplish this.

Second, let’s consider the problem of environmental impact. Doubling livestock production through traditional breeding techniques increases pressure on natural resources—water, land and biodiversity. So the need for enhanced efficiency without degrading natural resources is urgent. Again, IVEP, which requires only laboratory equipment in the production process, comes to the rescue.

Third, there is the biodiversity issue. Matching genotypes to environment is crucial. Scientists need to take several factors into consideration—among them adaptation, tolerance for disease, tolerance for new environments and alignment to market development. Although plenty of genetic diversity exists, thus far we’ve done little with it. Once more, IVEP could be the answer.

Fourth, IVEP has significant commercial potential because farmers can rent their best cows as donors and their lower-quality cows as surrogates.

Most importantly, we need to look closely at the constraints faced by small-scale livestock keepers.

  • Cattle genotypes and production environments, as often as not, do not match. Result:  low productivity.
  • Heifer replacement programs take a long time and are rarely done properly. Result: supply is low, prices are high.
  • Sex ratios are often disadvantageous. Result: too many males and high production costs.
  • The commercial relevance of many indigenous breeds is not optimised. Result: farmers incur unsupportable losses.
  • Programs for breed conservation and preservation are often improper. Result: some breeds are threatened by extinction and no gene pool for replacement exists.

IVEP does not—and should not—completely replace traditional reproductive technologies such as conventional embryo transfer (ET) and artificial insemination. Each of these techniques has its place, and each of them utilizes tissues, embryos and semen for improvement and reconstruction of cattle breeds. The difference is that while the traditional ET techniques involve more animals and are wholly done in the field, IVEP is undertaken in the lab and involves fewer surrogate animals in the field. IVEP eliminates the tedious steps of synchronizing donor cows.

Specifically, IVEP technology as a breeding tool has the distinct advantage of maximizing utilization of appropriate dam and sire genotypes by:

  • increasing efficiency of multiplication in breeding;
  • permitting  determination of sex of the offspring; and
  • permitting pre-testing of actual fertility status of the bull.

Thus, while natural mating or artificial insemination are necessarily slow and inefficient, producing only 10-15 offspring per life span of a cow …

…IVEP can produce up to 300 offspring per life span.

The SIFET Project: a successful IVEP program
The Sexed semen in-vitro fertilization and embryo transfer (SIFET) project was designed to exploit and promote the potential of applying IVEP reproductive technique to:

  • develop, multiply and disseminate female crossbreeds that appropriately match with production environment;
  • provide a system to preserve top bovine genotypes in cases of accidental culling in a recycle-like scheme (slaughterhouse collection); and
  • identify, multiply and conserve selected superior desirable breed traits.

The project involved collecting ovaries from slaughter houses or picking ovum from live cows. When the genetic material is brought to the lab, oocytes with high developmental competence are selected and morphological evaluation done. Once the ideal oocytes are identified, they are matured in vitro for 22-24 hours. The subsequent in vitro fertilization process is conducted for a period of 18-22 hours with a high sperm concentration. The fertilization itself requires removal of seminal plasma and extenders, separation of motile sperms from dead ones and induction of sperm capacitation. Once the embryos are formed, they are cultured in the lab for 7 days and then transferred to surrogates.

A conception rate of about 40% has been achieved, with calves born without abnormalities.

Conclusions

  1. IVEP technology is feasible in Kenya.
  2. Commercialization of the process should be facilitated as soon as supportive policies and proper legal/regulatory frameworks are in place

Challenges
Poor field heat detections leading to poor uterine synchrony and lower conceptions are concerns, as is the high genotype variability characteristic of animals brought to slaughterhouses.

Way forward and prospects
Looking ahead, the collaborating scientists anticipate bringing ovum pick-up (OPU) and cryopreservation into the picture as well as capacity building.

Clearly, such programs can help match breeds to appropriate production systems to ensure sound breeding programs. Where and when necessary, new breeds can be introduced within a relatively short period of time. Above all, embryos are far easier to transport across continents than live animals.

Through IVEP technology and well-planned crossbreeding programs such as SIFET that integrate the use of indigenous cows as donors and surrogates while using semen from appropriate (more productive and reasonably adapted) dairy breeds such as Jerseys, F1 heifers suited to the smallholder farmers’ conditions can be produced.

Niche markets for the technology and its F1 products should be further explored and exploited, notably with regard to the potential of forestalling the threat to key wildlife species.

New study warns that climate change could create agricultural winners and losers in East Africa

While predicting highly variable impacts on agriculture by 2050, experts show that with adequate investment the region can still achieve food security for all

Forage Diversity field on ILRI Addis campus

As African leaders prepare to present an ambitious proposal to industrialized countries for coping with climate change in the part of the world that is most vulnerable to its impacts, a new study points to where and how some of this money should be spent. Published in the peer-reviewed journal Agricultural Systems, the study projects that climate change will have highly variable impacts on East Africa’s vital maize and bean harvests over the next two to four decades, presenting growers and livestock keepers with both threats and opportunities.

Previous estimates by the study’s authors projected moderate declines in the production of staple foods by 2050 for the region as a whole but also suggested that the overall picture disguises large differences within and between countries. The new findings provide a more detailed picture than before of variable climate change impacts in East Africa, assessing them according to broadly defined agricultural areas.

‘Even though these types of projections involve much uncertainty, they leave no room for complacency about East Africa’s food security in the coming decades,’ said the lead author of the new study, Philip Thornton of the International Livestock Research Institute (ILRI), which is supported by the Consultative Group on International Agricultural Research (CGIAR). ‘Countries need to act boldly if they’re to seize opportunities for intensified farming in favored locations, while cushioning the blow that will fall on rural people in more vulnerable areas.’

The researchers simulated likely shifts in cropping, using a combination of two climate change models and two scenarios for greenhouse gas emissions, together with state-of-the-art models for maize and beans, two of the region’s primary staple foods.

In the mixed crop-livestock systems of the tropical highlands, the study shows that rising temperatures may actually favor food crops, helping boost output of maize by about half in highland ‘breadbasket’ areas of Kenya and beans to much the same degree in similar parts of Tanzania. Meanwhile, harvests of maize and beans could decrease in some of the more humid areas, under the climate scenarios used in the study. Across the entire region, production of both crops is projected to decline significantly in drylands, particularly in Tanzania.

‘The emerging scenario of climate-change winners and losers is not inevitable,’ said ILRI director general Carlos Seré. ‘Despite an expected three-fold increase in food demand by 2050, East Africa can still deliver food security for all through a smart approach that carefully matches policies and technologies to the needs and opportunities of particular farming areas.’

At the Seventh World Forum on Sustainable Development, held recently in Ouagadougou, Burkina Faso, African leaders announced a plan to ask the industrialized world to pay developing countries USD67 billion a year as part of the continent’s common negotiating position for December’s climate talks in Copenhagen.

The ILRI study analyzes various means by which governments and rural households can respond to climate change impacts at different locations. In Kenya, for example, the authors suggest that shifting bean production more to the cooler highland areas might offset some of the losses expected in other systems.

Similarly, Tanzania and Uganda could compensate for projected deficits in both maize and beans through increased regional trade. In the Common Market for Eastern and Southern Africa (COMESA), maize trade is already worth more than USD1 billion, but only 10 percent of it occurs within the region. As grain prices continue to rise in global markets, several East African countries will be well positioned to expand output of maize and beans for regional markets, thus reducing reliance on imports and boosting rural incomes.

Where crop yields are expected to decline only moderately because of climate change, past experience suggests that rural households can respond effectively by adopting new technologies to intensify crop and livestock production, many of which are being developed by various CGIAR-supported centres and their national partners.

Drought-tolerant maize varieties, for example, have the potential to generate benefits for farmers estimated at USD863 million or more in 13 African countries over the next 6 years, according to a new study carried out by the International Maize and Wheat Improvement Center (CIMMYT) and International Institute of Tropical Agriculture (IITA). Meanwhile, new heat-tolerant varieties of productive climbing beans, which are traditionally grown in highlands, are permitting their adoption at lower elevations, where they yield more than twice as much grain as the bush-type beans grown currently, according to Robin Buruchara of the International Center for Tropical Agriculture (CIAT).

In areas that face drastic reductions in maize and bean yields, farmers may need to resort to more radical options, such as changing the types of crops they grow (replacing maize, for example, with sorghum or millet), keeping more livestock or abandoning crops altogether to embrace new alternatives, such as the provision of environmental services, including carbon sequestration.

This latter option could become a reality under COMESA’s Africa Biocarbon Initiative, which is designed to tap the huge potential of the region’s diverse farmlands and other rural landscapes, ranging from dry grasslands to humid tropical forests, for storing millions of tons of carbon. The initiative offers African negotiators an appealing option in their efforts to influence a future climate change agreement.

‘If included in emissions payment schemes, this initiative could create new sources of income for African farmers and enhance their resilience to climate change,’ said Peter Akong Minang, global coordinator of the Alternatives to Slash-and-Burn (ASB) Programme at the World Agroforestry Centre. ‘Its broad landscape approach would open the door for many African countries to actively participate in, and benefit from, global carbon markets.’

‘Rural people manage their livelihoods and land in an integrated way that encompasses many activities,’ said Bruce Campbell, director of the CGIAR’s Challenge Program on Climate Change, Agriculture and Food Security. ‘That’s why they need integrated options to cope with climate change, consisting of diverse innovations, such as drought-tolerant crops, better management of livestock, provision of environmental services and so forth.’

How rapidly and successfully East African nations and rural households can take advantage of such measures will depend on aggressive new investments in agriculture, CGIAR researchers argue. According to a recent study by the International Food Policy Research Institute (IFPRI), it will take about USD7 billion annually, invested mainly in rural roads, better water management and increased agricultural research, to avert the dire implications of climate change for child nutrition worldwide.

About 40 per cent of that investment would address the needs of sub-Saharan Africa, where modest reductions projected for maize yields in the region as a whole are expected to translate into a dramatic rise in the number of malnourished children by 2050. Thornton’s projections probably underestimate the impacts on crop production, because they reflect increasing temperatures and rainfall changes only and not greater variability in the weather and growing pressure from stresses like drought and insect pests.

‘Farmers and pastoralists in East Africa have a long history of dealing with the vagaries of the weather,’ said Seré. ‘But climate change will stretch their adaptive capacity beyond its limits, as recent severe drought in the region has made abundantly clear. Let’s not leave rural people to fend for themselves but rather invest significantly in helping them build a more viable future.’

What a 5-degree world will look like in Africa

Mozambique, Angonia province, nr Ulongwe town

At the end of September 2009, Phil Thornton, agricultural systems analyst at the International Livestock Research Institute (ILRI), made a presentation at an international climate conference in Oxford called ‘Four Degrees & Beyond.’ The research he presented was conducted with Thornton’s long-term colleague, Peter Jones, of Waen Associates (UK).

Thornton and Jones have looked at the probable impacts of climate change on agriculture in sub-Saharan Africa and what needs to be done about this. Africa’s population will grow from 0.8 billion today to some 1.8 billion by 2050. Already, over 40% of Africans live in urban areas, and this urbanization will only increase in future, greatly increasing the continent’s need for food to feed all its urban dwellers.

The prognosis for agriculture is mixed in Africa, where yields per hectare have already stagnated. Climate change is critically important to Africa because the gross domestic product and levels of rainfall are highly correlated here. Any change in rainfall and rainfall variability is likely to bring associated economic change. Given all this, the authors asked themselves if  ‘it can all be held together’ in the future.

Several research studies indicate that yields of major cereals will be reduced by 10 to 30% to mid-century and beyond, although yields will vary widely depending on the crop grown and the location of the farming system. Regarding the impacts of a temperature increase of 5-degrees centigrade on growing seasons and crop yields, southern Africa is likely to experience 20% or more losses in length of growing periods. Thornton said we can expect under a 5 degree C increase many more ‘failed seasons’ in the 2090s, especially in southern Africa, the northern Sahel and the Horn of Africa. Most of rainfed agriculture in regions south of the Zambezi River is likely to become unviable and in much of East Africa, maize yields could fall by 26% and beans by 54%.

Prognosis
A 5-degree centigrade temperature increase will thus increase crop failure in much of sub-Saharan Africa, which will then require massive increases in intensive cropping in the highlands to feed all the people living in urban areas. In more marginal lands, many farmers will be forced to make radical transitions in their livelihoods, turning from cropping to livestock keeping, for example, or abandoning agriculture altogether.

The prognosis for a +5°C SSA
Croppers and livestock keepers have been highly adaptable to short- and long-term variations in climate. But the changes in a plus five-degree world would be way beyond experience. Number of people at risk from hunger has never been higher: 300 million in 1990, 700 million in 2007, and close to 1 billion in 2010 (FAO).

What needs to be done
We need to assess the limits of adaptation to climate change in Africa. And we need to develop comprehensive tools with which to analyze trade offs between, for example, economic growth and food security. We need to build on the adaptive capacity of Africa’s croppers and livestock keepers, increase our investments in agricultural and livestock development, and get the development paradigm for Africa right—one that builds on local, indigenous skills, knowledge and culture.

Mostly what we need to do is to avoid, at all costs, a 5-degree plus world.

Ireland’s Minister of State for Overseas Development, Mr. Peter Power, T.D., has launched an exhibition highlighting the potential of science for Africa’s smallholder farmers at the Irish Aid Volunteering and Information Centre in Dublin.

The multimedia exhibition features videos, posters, photographs and soundscapes that introduce visitors to the people of Khulungira, a village in Malawi that has benefited from advances in agricultural research.

“At present, one in six people worldwide go to bed hungry each night and many more cannot afford a healthy diet,” Mr. Power said. “If we do not do all in our power to reverse the rise in food insecurity and hunger, we will be failing in our basic human obligations, and accepting a scandalous situation which we have the capacity to change.”

The exhibition presents the people behind the grim statistics. The villagers of Khulungira are typical of millions of Africans who depend on smallholder farming for food and income. The challenges they face are daunting: If the rains are late, or crops are infested with a pest or disease, people can starve. If conditions are good, they may have a little extra to sell for income, enabling them to send their children to school. In this sort of scenario, even the smallest improvement in productivity can make a huge difference.

Thanks in part to research undertaken by the members of the Consultative Group on International Agricultural Research (CGIAR), farmers in Khulungira and other villages across Malawi have begun to plant new varieties of potatoes, sweet potatoes, groundnuts and trees. Others are improving the composition of soil and expanding their livestock holdings.

In each case, the change has increased production, improved diets and reduced vulnerability to catastrophic loses.

The CGIAR, established in 1971, is a strategic partnership of countries, international and regional organizations and private foundations dedicated to mobilizing agricultural science to reduce poverty, promote agricultural growth and protect the environment. The CGIAR supports an alliance of 15 international agricultural research centres.

Minister of State for Overseas Development Peter Power launches

The exhibition in Dublin features the work of four CGIAR centers: the World Agroforestry Centre (ICRAF), International Livestock Research Institute (ILRI), International Potato Center (CIP), and International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). The creative development of the joint venture was led by ILRI at the request of Irish Aid . Support was also provided by the MDG Centre, East & Southern Africa and Irish Aid, the Government of Ireland’s programme for overseas development.

In 2009, Irish Aid has provided funding of almost €7 million to the CGIAR. “Continued investment in agricultural research is essential to success in transforming African agriculture into a highly-productive, sustainable system that can assure food security, keep children in school and lift millions out of poverty,” Minister Power said.

The exhibition is free and open to the public at the Irish Aid Volunteering and Information Centre, 27-31 Upper O’Connell St, Dublin 1 (corner of Cathal Brugha Street). It is scheduled to run through the end of 2009.

Drought hits Kenya’s livestock herders hard

Llivestock in the current kenya drought

Drought hits Kenya’s livestock herders hard, forcing some communities out of self-reliant pastoral ways of life (photo credit: ILRI/Mann).

Stories of the two-year drought biting deep in pastoral lands in the Horn of Africa are heartbreaking. Kenya’s livestock herders are being hit particularly hard. More than three-quarters of Kenya comprises arid and semi-arid lands too dry for growing crops of any kind. Only pastoral tribes, able to eke out a living by raising livestock on common grasslands, can make a living for themselves and their families here, where rainfall is destiny. With changes in the climate bringing droughts every few years in this region of eastern Africa, some doubt that traditional pastoral ways of life, evolved in this region over some 12,000 years, can long survive. Climate change here is not an academic discussion but rather a matter of life and death. But pastoral knowledge of how to survive harsh climates—largely by moving animals to take advantage of common lands where the grass is growing—is needed now more than ever.

This is especially true in Africa, whose many vast drylands are expected to suffer greater extremes in climate in future. Two of the recent reports are from America’s Public Radio International (‘Drought in East Africa’: <http://www.pri.org/business/nonprofits/drought-east-africa1629.html>) and the UK’s Guardian newspaper (‘The last nomads: Drought drives Kenya’s herders to the brink’: <http://www.guardian.co.uk/world/2009/sep/13/drought-kenya-nomads>). The Guardian article tells a heart-breaking story about “pastoral dropouts”, a story that may mark “not simply the end . . . of generations of nomadic existence in the isolated lands where Kenya meets Somalia and Ethiopia, but the imminent collapse of a whole way of life that has been destroyed by an unprecedented decade of successive droughts”.

The article says this region has experienced three serious droughts in the last decade, when formerly a drought occurred every 9 to 12 years. This change in global weather patterns ‘has been whittling away at the nomads’ capacity to restock with animals—to replenish and survive—normally a period of about three years”. The Economist in its 19 September 2009 edition says global warming is creating a ‘bad climate for development’ (<http://www.economist.com/world/international/displaystory.cfm?story_id=14447171>). The article says that poor countries’ economic development will contribute to climate change—but they are already its victims. ‘Most people in the West know that the poor world contributes to climate change, though the scale of its contribution still comes as a surprise. Poor and middle-income countries already account for just over half of total carbon emissions (see chart 1); Brazil produces more CO2 per head than Germany. The lifetime emissions from these countries’ planned power stations would match the world’s entire industrial pollution since 1850.

‘Less often realised, though, is that global warming does far more damage to poor countries than they do to the climate. In a report in 2006 Nicholas (now Lord) Stern calculated that a 2°C rise in global temperature cost about 1% of world GDP. But the World Bank, in its new World Development Report <http://www.economist.com/world/international/displaystory.cfm?story_id=14447171#footnote1> , now says the cost to Africa will be more like 4% of GDP and to India, 5%. Even if environmental costs were distributed equally to every person on earth, developing countries would still bear 80% of the burden (because they account for 80% of world population). As it is, they bear an even greater share, though their citizens’ carbon footprints are much smaller . . . . ‘The poor are more vulnerable than the rich for several reasons. Flimsy housing, poor health and inadequate health care mean that natural disasters of all kinds hurt them more. ‘The biggest vulnerability is that the weather gravely affects developing countries’ main economic activities—such as farming and tourism. Global warming dries out farmland. Since two-thirds of Africa is desert or arid, the continent is heavily exposed. One study predicts that by 2080 as much as a fifth of Africa’s farmland will be severely stressed.’

The International Livestock Research Institute (ILRI) and its local and international partners are working to help pastoral communities in this region increase their resilience in the face of the current drought, as well as population growth, climate change, and other big changes affecting pastoral ways of life.

  1. Scientists are helping Maasai communities in the Kitengela rangelands of Kenya (outside Nairobi) obtain and use evidence that new schemes to pay herders small sums of money per hectare to keep their lands unfenced are working for the benefit of livestock and wildlife movements alike.
  2. Scientists are helping Maasai communities in the rangelands surrounding Kenya’s famous Masai Mara National Reserve to obtain and use evidence that public-private partnerships now building new wildlife conservancies that pay pastoralists to leave some of their lands for wildlife rather than livestock grazing are win-win options for conservationists and pastoral communities alike.
  3. Scientists have refined and mass produced a vaccine against the lethal cattle disease East Coast fever—and are helping public-private partnerships to regulate and distribute the vaccine in 11 countries of eastern, central and southern Africa where the disease is endemic—so that pastoral herders can save some of their famished livestock in this drought from attack by disease, and use those animals to rebuild their herds when the drought is over.
  4. Scientists are characterizing and helping to conserve the indigenous livestock breeds that Africa’s pastoralists have kept for millennia—breeds that have evolved special hardiness to cope with harsh conditions such as droughts and diseases—so that these genetic traits can be more widely used to cope with the changing climate.

But much more needs to be done. And it needs to be done much more closely with the livestock herding communities that have so much to teach us about how to cope with a changing and variable climate.

African cattle to be protected from killer disease

ITM Vaccine

Millions of African families could be saved from destitution thanks to a much-needed vaccine that is being mass-produced in a drive to protect cattle against a deadly parasite.

East Coast fever is a tick-transmitted disease that kills one cow every 30 seconds – with one million a year dying of the disease.

Calves are particularly susceptible to the disease. In herds kept by the pastoral Maasai people, for example, the disease kills from 20 to over 50 per cent of all unvaccinated calves. This makes it difficult and often impossible for the herders to plan for the future, to improve their livestock enterprises and thus to raise their standard of living.

An experimental vaccine against East Coast fever was first developed more than 30 years ago. This has been followed by work to allow the vaccine to be produced on a large scale, with major funding from the UK Department for International Development (DFID) and others.

East Coast Fever puts the lives of more than 25 million cattle at risk in the 11 countries where the disease is now endemic, and endangers a further 10 million animals in new regions such as southern Sudan, where the disease has been spreading at a rate of more than 30 kilometres a year. The vaccine could save the 11 affected countries at least £175 million a year.

The immunization procedure – called “infection-and-treatment” because the animals are infected with whole parasites while being treated with antibiotics to stop development of disease – has proved highly effective. However, initial stocks produced in the 1990s recently ran low.

The International Livestock Research Institute (ILRI), at the request of the Africa Union/Interafrican Bureau for Animal Resources and chief veterinary officers in affected countries, produced one million doses of vaccine to fill this gap. However, for the longer term it is critical that sustainable commercial systems for vaccine production, distribution and delivery are established.

With UK£16.5 million provided by DFID and the Bill & Melinda Gates Foundation, the charity GALVmed is fostering innovative commercial means to do just this, beginning with the registration and commercial distribution and delivery of this new batch of the vaccine. This will ensure that the vaccine is made available, accessible and affordable to livestock keepers who need it most and to scale up its production for the future.

International Development Minister Mike Foster said:
“Some 1.3 billion of the world's poorest people rely on livestock for their livelihoods. Many Africans depend on the health of their cattle for milk, meat and as their only hard asset for trade and investment. A smallholder dairy farmer can take years to recover economically from the death of a single milking cow. That’s why it’s vital that every possible step is taken to ensure that these essential vaccine doses are sustainably produced, tested and made available to the people who need them.

“DFID is supporting GALVmed to explore ways of transferring the production and distribution of the vaccine into the private sector through local manufacturers and distributors. This is extremely important in making the vaccine affordable, accessible and – crucially – sustainable.”

GALVmed CEO Steve Sloan said:
“Funded by DFID and the Bill & Melinda Gates Foundation, GALVmed is working to protect livestock and the livelihoods of their owners. Thanks to the highly effective East Coast fever vaccine developed over many years by researchers working in East Africa and then refined and mass produced by ILRI, cattle invaluable to pastoralists such as the Maasai as well as smallholder dairy farmers are being protected. 
“The survival of cattle for the millions who live on tiny margins has a direct effect on quality of life and the dignity of choice and self-determination. Collaborating with ILRI and partners in the developing world, including governments and veterinary distributors and those from the private sector, GALVmed is working to embed the vaccine through registration in East African countries and to scale up its production so that it remains accessible to poor people.
“This pioneering registration effort aims to ensure that the vaccine is approved and monitored by affected nations and enables local firms to sell and distribute it, embedding its sustainability. Registration in Malawi is already complete, with significant progress in Tanzania, Kenya and Uganda.”
ILRI veterinary scientist Henry Kiara, who has conducted research on the live vaccine for 20 years, explains that ILRI is “looking forward to commercialising the production, distribution and delivery of the vaccine to the smallholder and emerging dairy producers as well as livestock herders” in this region of Africa. “Now that all the building blocks are in place, thanks to past investments by DFID and others”, he says, “we are excited to be at a stage where this vaccine can ‘take off’.”

Over the past several years, the field logistics involved in mass vaccinations of cattle with the infection-and-treatment method have been greatly improved, due largely to the work of a private Company called VetAgro Tanzania Ltd, working with Maasai cattle herders in northern Tanzania. Sustainability underpins GALVmed’s approach and the charity is working with developing world partners to ensure that the vaccine is available to those who need it most, bringing public and private partners together.


About the vaccine
The infection-and-treatment immunisation method against East Coast fever was developed by research conducted over three decades by the East African Community, the Kenya Agricultural Research Institute (KARI) at Muguga, Kenya (www.kari.org), and the International Livestock Research Institute (ILRI), in Nairobi, Kenya (www.ilri.org). This long-term research was funded by the UK Department for International Development (DFID) (www.dfid.gov.uk) and other donors of the Consultative Group on International Agricultural Research (CGIAR) (www.cgiar.org). The first bulk batch of the vaccine, produced by ILRI 15 years ago, has protected one million animals, whose survival raised the standard of living for livestock keepers and their families. Field trials of the new vaccine batch, also produced at ILRI, are being completed in accordance with international standards to ensure that it is safe and effective.

About East Coast fever
East Coast fever was first recognized in southern Africa when it was introduced at the beginning of the twentieth century with cattle imported from eastern Africa, where the disease had been endemic for centuries. It caused dramatic losses with high cattle mortality. It has persisted in 11 countries in eastern, central and southern Africa – Burundi, Democratic Republic of Congo, Kenya, Malawi, Mozambique, Rwanda, Sudan, Tanzania, Uganda, Zambia and Zimbabwe. The disease devastates the livelihoods of small-scale mixed crop-and-livestock farmers and smallholder and emerging dairy producers, as well as pastoral livestock herders, such as the Maasai in East Africa.

East Coast fever, or theileriosis, is a devastating cancer-like disease of cattle that often kills the animals within three weeks of infection. It is caused by the single-celled parasite Theileria parva, which is transmitted by the brown ear tick (Rhipicephalus appendiculatus) as it feeds on cattle. In addition to producing the infection-and-treatment vaccine, ILRI is also working to develop a genetically engineered next-generation vaccine.

Some 70 per cent of the human population of sub-Saharan Africa – around half a billion people – depend on livestock for their livelihoods, with farming and herding families relying on cattle for vital sources of food, income, traction, transportation and manure to fertilise croplands.

A case study showing the impact of the disease on Maasai herders is included below. Further case studies illustrating the impact of the infection-and-treatment vaccine on people’s lives are available on the GALVmed website at: www.galvmed.org/path-to-progress

Case Study: East Coast fever in Tanzania
Maasai herders in Tanzania have been particularly devastated by East Coast fever. In parts of northern Tanzania, more than 1 in 5 calves die before reaching maturity (54 months) in the lowlands and more than one third fail to reach maturity in the (wetter) highlands, where tick-borne and other diseases are more prevalent.

Although the infection-and-treatment vaccine is a “live” vaccine, and thus needs to be stored in liquid nitrogen and administered by skilled practitioners, after which the animals must be monitored by experts for several days, the Maasai here are desperate for the new batch to be ready.

Introduction of the previous batch in recent years has drastically reduced calf mortality, from up to 80 per cent to less than 2 per cent. The protection afforded by the vaccine is so good that Maasai herders are willing to pay for these vaccinations. The vaccine appears to protect the animals against other ailments as well and, in addition, those mature animals that are marked with ear tags as having been vaccinated are fetching up to 50 per cent higher prices in the market. The vaccine is allowing these cattle herders to sell more animals and to invest their new income in, for example, bettering their household diets or paying for their children’s education. The new access to this vaccine is facilitating a transition among the Maasai in herd management, from a subsistence- to a market-orientation.

GALVmed has regular contact with those on the ground to improve access to the vaccine, including a meeting with 25 Masaai livestock keepers in Arusha, in northern Tanzania, earlier this year. At that meeting a Masaai representative stated:

“Please thank all those people who made the vaccine and also those who make it available for us to buy. Tell them not to stop their good work. No cattle means no Maasai – and no East Coast fever vaccine means no cattle.”

Neue Studie: Bei immer wärmerem Wetter und sich verändernden Niederschlagsmustern könnte der Viehbestand für die afrikanische Landwirtschaft überlebenswichtig werden

Einer neuen Studie von Forschern des International Livestock Research Institute (ILRI) in Nairobi sowie der britischen Waen Associates zufolge könnten wärmere klimatische Bedingungen im Verein mit sich verändernden Niederschlagsmustern bis zum Jahr 2050 dazu führen, dass 500 0000 bis eine Million Quadratkilometer marginaler afrikanischer Anbauflächen nicht mehr in der Lage sein werden, die Produktion einer für den eigenen Lebensunterhalt ausreichenden Menge von Feldfrüchten zu unterstützen. Das Land, auf dem derzeit etwa 20 bis 35 Millionen Menschen leben, kann allerdings nach wie vor der Viehzucht dienen.

Für Millionen armer Landwirte in ganz Afrika könnte die Verstärkung der Viehproduktion eine attraktive Alternative bieten. In den kommenden Jahrzehnten werden sie möglicherweise feststellen, dass sich ihr Land aufgrund des Klimawandels zwar nicht mehr für den Ackerbau verwenden lässt, aber immer noch für die Aufzucht von Tieren geeignet ist. Das ergab eine Studie, die in dieser Woche in einer Sonderausgabe der Zeitschrift Environmental Science and Policy erscheint.

„Tiere, vor allem solche, die bekanntermaßen Hitze und Dürre gut vertragen, können in Bedingungen überleben, die für Feldfrüchte viel zu hart sind“, sagte ILRI-Wissenschaftler Philip Thornton, einer der Autoren des Beitrags. „Viehbestände können arme Haushalte vor den Risiken des Klimawandels schützen, und sie ermöglichen ihnen, von der wachsenden Nachfrage nach Tierprodukten in Afrika zu profitieren.“

„Der Viehbestand muss nachhaltig gesteigert werden“, sagte Carlos Seré, Generaldirektor des ILRI, eines der 15 von der Consultative Group on International Agricultural Research (Beratungsgruppe für internationale Agrarforschung, CGIAR) geförderten Forschungszentren. „Unsere Forschungen haben ergeben, dass in zahlreichen Gebieten Afrikas während der kommenden Jahrzehnte klimatische Anfälligkeiten im Verein mit der Marktnachfrage nach Tierprodukten viele Agrargemeinschaften dazu bringen werden, den Viehbestand ihrer Landwirtschaft zu vergrößern. Auf diesen zwangsläufigen Umstand müssen wir uns bereits heute vorbereiten.”

Die Untersuchung gehört zu einer in der Zeitschrift veröffentlichten Studienreihe, die aus einer Konferenz an der Oxford University über Nahrungsmittelsicherheit und Umweltwandel im April 2008 hervorging. Ihre Veröffentlichung fällt mit einer Konferenz zusammen, die in dieser Woche in Bonn stattfindet. Dort werden Experten aus der ganzen Welt erörtern, wie ein neues, weltweites Klimawandel-Abkommen der armen Landbevölkerung Anpassungsstrategien zur Verfügung stellen kann.

Thornton und sein Kollege Peter Jones von den britischen Waen Associates ermittelten zunächst, welche von der Landwirtschaft abhängigen Gebiete Afrikas am anfälligsten für die Auswirkungen des Klimawandels sind. Ihr Hauptaugenmerk legten sie dabei auf so genannte marginale Anbauflächen – trockene und halbtrockene Regionen West-, Ost- und Südafrikas, wo beispielsweise karge Niederschläge bereits jetzt regelmäßig in einer von sechs (oder
weniger) Anbauperioden zu Ernteausfällen führen.

Sodann untersuchten die Forscher die Auswirkungen des Klimawandels in diesen Regionen. Sie fanden heraus, dass selbst dann, wenn der Klimawandel durch weltweit reduzierte Kohlenstoffemissionen etwas gemäßigt wird, höchstwahrscheinlich immer noch eine große Zahl von Landwirten mit einer Verschlechterung der Anbaubedingungen rechnen muss. Maßgeblich war dabei in erster Linie die Frage, ob der Klimawandel gemäß zwei weit verbreiteten Klimamodellen – mit Vorhersagen auf der Grundlage von Szenarien hoher und niedriger Treibhausgasemissionen – dazu führen kann, dass die Anzahl der „sicheren Anbautage“ in den Jahren 2000 bis 2050 auf unter 90 sinkt.

Die Forscher kamen zu dem Schluss, dass bei Szenarien mit unverändert hohen Kohlenstoffemissionen die Anzahl der sicheren Anbautage für fast eine Million Quadratkilometer marginaler Anbauflächen in Afrika auf unter 90 sinken würde. Auf der Grundlage eines „niedrigeren Emissionsszenarios“ sagen sie voraus, dass etwa 500 000 Quadratkilometer die 90-Tage-Marke verfehlen würden.

Die Forscher warnen davor, dass dann, wenn in diesen Gebieten die Dauer der sicheren Anbauperioden auf unter 90 Tage sinkt, „der jetzt bereits marginale Maisanbau als normale landwirtschaftliche Tätigkeit im Grunde genommen nicht mehr möglich sein wird.“ An einigen Stellen könne der Regen so knapp werden, dass „selbst dürrebeständige Feldfrüchte wie Hirse“ schwer anzubauen sein werden. Unter diesen Bedingungen könne das Vieh für die
Ernährung ebenso entscheidend werden wie für die Erzielung von Einkünften.

Der Studie zufolge ermöglicht der Viehbestand insbesondere jenen auf marginalen Anbauflächen ums Überleben kämpfenden Landwirten eine erhebliche Einkommenssteigerung, die nicht weiter als eine Tagesreise von einer der afrikanischen Städte entfernt sind. Dort könnte eine wachsende Nachfrage nach Fleisch und Milchprodukten lukrative Märkte eröffnen.

Thornton und Jones wiesen darauf hin, dass es keine neue Idee ist, das Vieh als Bollwerk gegen schwierige klimatische Bedingungen zu betrachten. In ganz Afrika, so merken sie an, „erwies sich das Vieh als wichtiger Bewältigungsmechanismus für Arme, die unter schwierigen Umweltbedingungen versuchen, ihr Auskommen zu sichern.“

Nach Aussage Thorntons besteht das Ziel der Forschungsarbeit letztlich darin, anhand von Klimawandel-Vorhersagen bestimmte, möglicherweise relativ kleine Gebiete in Afrika auszumachen, wo es sich lohnt, den Besitz von Vieh auf Kleinbauernhöfen zu fördern und den Landwirten beim Umgang mit den damit einhergehenden Risiken zu helfen. Diese Art von Forschung könne allerdings, sollte sie zur Beeinflussung politischer Entscheidungen herangezogen werden, in hohem Maße von der Erhebung besserer Daten profitieren. Hierzu zählen Daten, mit denen mögliche Ortstemperaturen und Niederschlagsmuster in der Zukunft vorhergesagt werden können.

Wie er und Jones allerdings einräumen, „herrscht derzeit ein Missverhältnis zwischen jener dringend erforderlichen Art von lokalisierten Informationen über Klimawandelauswirkungen und dem, was objektiv zur Verfügung steht.“

So bestehe etwa ein Konsens darüber, dass die Temperaturen signifikant ansteigen werden. Doch stimmten in großem, regionalem Maßstab verschiedene Klimamodelle nicht immer darin überein, in welchem Ausmaß der Klimawandel Regenmengen und Niederschlagsmuster in einigen Teilen Afrikas beeinflussen könnte. Investitionen zur Beschaffung derartiger Angaben böten jedoch mit Sicherheit die Möglichkeit, Hilfsprogramme zur Linderung der Armut unter der armen Landbevölkerung Afrikas, deren Ernährung und Einkommen meistens von Kleinbauernhöfen abhängt, mit einem neuen Maß an Präzision und Effizienz auszustatten.

Wie die Forscher außerdem anmerken, werden bessere Daten unausweichlich eine Tatsache offenbaren, die manche nicht wahr haben wollen, der man aber dennoch ins Auge blicken muss: In einigen Teilen Afrikas, wo die Anbaubedingungen jetzt bereits schwierig sind, stoßen die Bemühungen, den Landwirten bei der Anpassung an den Klimawandel zu
helfen, ganz einfach an ihre Grenzen. So hart diese Tatsache sein mag – laut Thornton und Jones müssen Entwicklungsagenturen und Regierungen eines verstehen: Bei zunehmend unwirtlichen klimatischen Bedingungen für die Landwirtschaft wird an einigen Orten möglicherweise „ein Punkt erreicht, an dem Haushalte und Agrarbetriebe so stark unter Druck geraten, dass es zu einer Aufgabe der Landwirtschaft nur wenig Alternativen gibt.“

Climate change models find maize, millet, other staple crops face ruin on up to one million square kilometers of African farmland

Livestock could be critical to survival of African Agriculture as hotter weather and rainfall patterns shift, says new study

Climate change models find maize A new study by researchers from the Nairobi-based International Livestock Research Institute (ILRI) and the United Kingdom’s Waen Associates has found that by 2050, hotter conditions, coupled with shifting rainfall patterns, could make anywhere from 500,000 to one million square kilometers of marginal African farmland no longer able to support even a subsistence level of food crops. However, the land, on which some 20 to 35 million people currently live, may still support livestock.

Boosting livestock production could be an attractive alternative for millions of poor farmers across Africa who, in the coming decades, could find that climate change has rendered their lands unsuitable for crop cultivation yet still viable for raising animals, according to the study that appears this week in a special edition of the journal Environmental Science and Policy.

“Livestock, particularly animals that are known to be tolerant of heat and drought, can survive in conditions that are far more severe than what crops can tolerate,” said Philip Thornton, an ILRI scientist and one of the paper’s co-authors. “Livestock can provide poor households with a buffer against the risk of climate change and, allow them to take advantage of the increasing demand for animal products in Africa.”

“Any increase in livestock must be managed sustainably,” said Carlos Seré, Director General of ILRI, which is one of 15 research centers supported by the Consultative Group on International Agricultural Research (CGIAR). “But our research shows there are many areas in Africa where over the next few decades climate vulnerability coupled with market demand for animal products will prompt many farming communities to add more livestock to their agriculture systems and we should prepare now for this inevitability. ”

The analysis is part of a range of studies published in the journal that emerged from an April 2008 conference at Oxford University on food security and environmental change. The publication coincides with a meeting this week in Bonn in which experts from around the world will consider how a new global accord on climate change can offer adaptation strategies for the rural poor.

Thornton and his colleague, Peter Jones of Waen Associates in the UK, sought to identify farm-dependent areas of Africa that might be most vulnerable to the effects of climate change. They focused on what are considered “marginal lands,” arid and semi-arid regions of West, East and southern Africa where, for example, scant precipitation already routinely causes crops to fail in one out of every six (or fewer) growing seasons.

The researchers then considered the impact of climate change in these regions and found that even in situations where climate change is moderated somewhat by global reductions in carbon emissions, a large number of farmers most likely will still face a considerable deterioration in growing conditions. The key measure was whether climate change under two widely used climate models—which offer projections based on high and low greenhouse-gas emission scenarios—would cause the number of “reliable crop growing days” to drop below 90 days between 2000 and 2050.

Mozambique, Tete province, Pacassa village

They concluded that under scenarios in which carbon emissions remain high, the number of reliable growing days would drop below 90 for almost one million square kilometers of marginal growing lands in Africa. Assuming a “lower emission scenario,” they project about 500,000 square kilometers would fail to reach the 90-day mark.

The researchers warn that if reliable growing periods drop below 90 days in these areas, “maize cultivation, already marginal, will basically no longer be possible as a normal agricultural activity.” They continue, saying that in some places, rain could become so scarce that “even the drought-tolerant crops such as millet” will be difficult to grow. They say that in these conditions, livestock could be the key to keeping food on the table and for earning income as well.

In particular, according to the study, livestock could provide a significant income boost for farmers trying to survive on marginal lands that are within a day’s travel time of one of Africa’s urban populations, where a growing demand for meat and dairy products could provide lucrative markets.

Thornton and Jones pointed out that looking to livestock as a bulwark against challenging climates is not a novel idea. They note that across Africa “livestock have proven to be a crucial coping mechanism for poor people who are trying to survive in difficult environmental conditions.”

Thornton said the goal of the research is ultimately to use climate change projections to pinpoint specific areas in Africa—each of which may be relatively small in size—where it is appropriate to promote livestock ownership on small-holder farms and to help farmers deal with the risks inherent in such operations. But he said employing this kind of research to direct policy decisions would benefit greatly from obtaining better data at the local level,
including data projecting what local temperatures and rainfall patterns may look like in the future.

However, he and Jones acknowledge that “there is currently a mismatch between the kind of localised climate change impact information that is urgently needed, and what can objectively be supplied.”

For example, even at large, regional levels, while there is consensus that temperatures will rise significantly, different climate models don’t always agree as to how climate change may affect rainfall amounts and patterns in some parts of Africa. But they said investments in generating such details are warranted given the potential to bring new levels of precision and efficiency to aid programs focused on alleviating poverty among the rural poor in Africa, most of whom depend on small holder farms for food and income.

The researchers also observe that better data will inevitably show what some may be reluctant to see, but which must be confronted nonetheless: that in certain parts of Africa where growing conditions already are difficult, there are simply limits to what can be done to help farmers adapt to climate change. Harsh reality though it may be, Thornton and Jones said it is important for development agencies and governments alike to understand that as climate conditions become more inhospitable to agriculture in some places, there may be “a point at which households and farming systems become so stressed that there are few alternatives to an exit from farming.”

Making research matter: Seven ways to link knowledge to action

Posted on by

Influential PNAS chooses ILRI and partner research on 'linking knowledge with action' for its latest issue (31 March 2009).

Making research matter Institutionalization of systems approaches and scaling out of project results arguably remain our greatest challenges in more successfully linking knowledge with action resulting in sustainable poverty reduction.

Is that true? A new paper published by Patti Kristjanson and colleagues at the International Livestock Research Institute (ILRI) in the prestigious Proceedings of the National Academy of Sciences in the US, thinks it is and argues for seven principles that might help us institutionalize and scale out what works best.

Researchers have traditionally focused on research outputs–articles, methods, technologies, trainings–rather than research outcomes. But it is by jointly defining with project partners the desired outcomes of a project–including changed behaviors, policies, and practices–that links between knowledge and action can be discerned and strengthened.

A group of 19 ILRI and partner researchers have analyzed a broad range of projects using a framework that discloses some helpful lessons. The synthesis of results published in PNAS is entitled ‘Linking International Agricultural Research Knowledge with Action for Sustainable Development’.

Patti Kristjanson, lead author of the paper, says, ‘This article describes ideas, principles and approaches I wish I had been exposed to when I began leading research teams tackling agricultural development and poverty issues across Africa 20 years ago’.

The researchers applied an innovation framework to sustainable livestock development research projects in Africa and Asia. The focus of these projects included pastoral systems, poverty and ecosystems services mapping, market access by the poor, fodder and natural resource management, and livestock parasite drug resistance. The framework arose from a series of propositions advanced at  a workshop organized by the Roundtable on Science and Technology for Sustainability of the US National Academies, led by Bill Clark who directs Harvard University’s Sustainability Science Program.  

So what helps to close gaps between knowledge and action? What helps take research knowledge beyond the realm of ‘knowledge for knowledge sake’ and convert it to changes in behaviour, practices, policies, institutions and uptake of new technologies?

“The framework is important because it is pragmatic and results oriented. In applying this framework we found that strategies key to closing gaps between knowledge and action include: combining different kinds of knowledge, learning and bridging approaches, strong and diverse partnerships that level the playing field, and building capacity to innovate and communicate” said Bill Clark, Harvey Brooks Professor of International Science, Public Policy and Human Development at Harvard’s Kennedy School of Government.

In examining what approaches, processes, tools and methods helped this very diverse range of project teams be successful in linking knowledge with action, the researchers found that 7 broad principles apply.

 How to ensure success or failure of getting your research into use

  1. Problem definition.
    DO: Define the problem to be solved in a collaborative and user-driven manner.
    HOW TO FAIL?: Separate yourselves (scientists who produce knowledge) from the decision-makers who use it.
  2. Program management.
    DO: Adopt a project orientation and organization and appoint dynamic leaders accountable for achieving user-driven goals.
    HOW TO FAIL?: Let your ‘study of the problem’ displace ‘creation of solutions’.
  3. Boundary spanning.
    DO: Use ‘boundary-spanning’ organizations, individuals and actions to help bridge gaps between research and research-user communities, construct informal arenas that foster producer-user dialogues, develop joint ‘rules of engagement’ and define products jointly.
    HOW TO FAIL?: Allow dominance by groups committed to the status quo.
  4. Systems integration.
    DO: Recognize that scientific research is just one ‘piece of the puzzle’ and apply systems-oriented strategies.
    HOW TO FAIL?: Don’t engage partners best positioned to help transform knowledge into useful strategies, policies, interventions or technologies.
  5. Learning orientation.
    DO: Design your project as much for learning as for knowing and to be frankly experimental, expect and embrace failures to learn from them throughout the project’s life.
    HOW TO FAIL?: Punish or fail to fund or reward risk-taking managers
  6. Continuity with flexibility.
    DO: Strengthen links between organizations and individuals operating locally, building strong networks and innovation/response capacity.
    HOW TO FAIL?: Leave development of communication strategies and products to the communication experts to do and development of research products for the researchers to do.
  7. Manage asymmetries of power.
    DO:  Level the playing field by generating hybrid, co-created knowledge.
    HOW TO FAIL?: Don’t deal with the often large (and largely hidden) asymmetries of power felt by stakeholders.

Boundary spanning
Boundary-spanning work takes place between two or more groups that work to different standards and objectives (e.g. basic scientists evaluated by peers versus action people who are validated by political processes). Boundary objects are joint creations at the interface of communities (e.g. models, maps, assessments, contracts, posters). Even more important than ‘boundary-spanning organizations’ are boundary-spanning individuals and efforts. Having said that, individuals work within institutional frameworks, and these need to be supportive of such work (or at the very least, not block it). We need to better understand what kinds of institutional change, if any, encourage or accelerate boundary work. As boundary-spanning activities, behaviors and approaches can be learned, developing courses and training materials in this area may profit research for development. These are environments where partners come together to solve problems and create joint outputs and reach agreement as to new rules of engagement that encourage and support creativity and innovation.

Tools and processes for boundary spanning. Examples of tools and processes that can help span boundaries efficiently and effectively via collaborative efforts include: outcome mapping (<http://www.outcomemapping.ca>), participatory impact pathway analysis (Douthwaite et al, 2003), farmer impact assessment workshops (Kristjanson et al, 2002), challenge dialogue process (<http://www.innovationexpedition.com>), policy evaluation framework (Cohan et al, 1994), adaptive management (www.adaptivemanagement.net), policy-focused assessment process (Schegara and Furrow 2001), joint fact-finding (<http://www.beyondintractability.org/>), value of information approach (Yokota and Thompson, 2004), institutional histories (<http://www.ciat.cgiar.org/riiweb/>), negotiation support (van Noordwijk et al, 2001), and appreciative inquiry (<http://www.cgiar-ilac.org>). ILRI’s community facilitator-researcher approach is another useful model (Nkedianye et al, 2008).

Systems integration
One way to produce both international public goods (those with significance across borders) and local poverty impacts is for research projects to engage local partners in multiple strategically selected sites to ensure the knowledge generated can be extrapolated more broadly. Does mission-oriented research always require a systems approach (e.g. involving public- and private-sectors, non-governmental organizations, community members, scientists, and policymakers)? All our case studies suggest the answer is yes.

There is certainly a role in sustainability science for both traditional, curiosity-driven research as well as for context-specific problem solving-so long as both are conducted within a larger framework that ensures rigor and usefulness. Many scientists fear that their adopting a systems approach will reduce their comparative advantage (e.g., in-depth knowledge of a disciplinary field) and lead to their spending all their time on partnership building and other processes. This risk is real. Our case studies all point to the need to use rigorous processes, ‘tried and tested’ tools, and world-class expertise in facilitating stakeholder engagement, building teams, and establishing ways to measure and communicate impacts and outcomes.

Learning orientation
All organizations interested in transforming themselves (or their self-perceptions) from knowledge producers to knowledge learners face challenges in doing so. Management must support a learning culture and provide incentives for adopting learning approaches, as it has at ILRI, where research performance criteria now include collaborative partnerships and communication outputs beyond scientific journal articles. But ILRI and other institutions ambitious to transform themselves into learning cultures need to go further in supporting and rewarding failures (as often encouraged in private sector research). Initiatives are needed to fund collaborative teams experimenting with different learning approaches to find those that help them link knowledge with action. A cultural and institutional environment that discourages risk taking and finds failures generally unacceptable adds considerably to the challenge of taking a learning-based approach. Convening the right team and committing to co-learning and co-producing ‘hybrid’ knowledge (e.g. a combination of indigenous and scientific knowledge) for action at the beginning of the project is absolutely critical to success. ILRI’s  pastoral project is a good example of how institutional ‘protection’ is needed to truly encourage innovative and risk-taking behavior; ILRI management and large external financial support effectively provided a safe space in the sense that the team was protected from external criticism concerning a livestock institute working on wildlife conservation issues.

The issue of improving incentives and rewards for individuals that are successful ‘boundary spanners’ arose in all the case studies. A critical challenge to institutionalizing boundary spanning functions within an organization is to do so while maintaining flexibility to adjust and organize according to constantly changing needs for specific information products. Many institutions are not eager to invest in boundary functions (e.g. workshops, forums, reports) that are perceived to be not a core part of their mission, nor do government or private funders want to invest in the creation of freestanding boundary organizations. We also saw ‘informal communities’ of actors who play no explicit role in the system-often making one-on-one connections between explicit actors who otherwise might not meet-creating key relationships. Because of their ‘stealth’ nature, these are very difficult to identify, yet can be important for successful boundary-spanning, and the links from knowledge to action, to occur.

Conclusion
We believe that projects aiming to improve livelihoods in sustainable ways will increase their likelihood of being successful if they incorporate most if not all of these seven propositions. The working paper explores some of the tools, processes, approaches and strategies that can help research teams apply these principles.

The good news is that these ILRI-partner results indicate that boundary-spanning work is most effective when it is regularized yet flexible and when it enlists the support of informal communities of actors. More research is needed on what kinds of institutional change are likely to encourage and accelerate boundary work, what kind of incentives are needed to encourage individuals to pursue such work, and what kinds of courses and training materials will build capacity in this area.

Climate and health experts warn that scientists must work together, or risk ‘disastrous consequences’ to human and animal health in Africa

Consensus: Spread of Malaria, Rift Valley fever, and Avian flu far more likely if researchers continue to ‘operate in silos’ and if solutions ignore local conditions.

human and animal health in Africa

Faced with the prospect of more variable and changing climates increasing Africa’s already intolerable disease burden, scientists must begin to reach out to colleagues in other fields and to the people they want to help if they hope to avert an expected “continental disaster,” according to leading climate, health, and information technology experts, who met in Nairobi last week.

Climate change will further increase the already high variability of Africa’s climate, fostering the emergence, resurgence and spread of infectious diseases. “A warmer world will generally be a sicker world,” said Prof. Onesmo ole-MoiYoi, a Tanzania medical, veterinary and vector expert. “We scientists need to adopt a new way of working, one that makes African communities bearing the burden of disease part of the solution rather than part of the problem.” The separate fields of human health, animal health, climate, vectors and environment must come together to avert a “continental disaster,” according to leading experts who attended the meeting.

Patti Kristjanson of ILRI, which hosted the meeting, agreed. “We need to do things differently than we have in the past. The impact of disease will increase if we continue to operate in silos. Our only chance at reducing the impact of deadly diseases in Africa is to increase collaboration across the disciplines of environment and health, and in a way that involves local communities. Failure to do so could lead to disastrous consequences.”

The experts concluded a three-day meeting sponsored by Google.org and organized by researchers from the IGAD Climate Predictions and Applications Centre (ICPAC), the Kenya Medical Research Institute (KEMRI), the International Centre of Insect Physiology and Ecology (icipe), the International Livestock Research Institute (ILRI) and Google.org.

The meeting was one of the first on the continent to link climate and health researchers to reduce Africa’s infectious disease burden. The experts cited malaria, Rift Valley fever and bird flu as diseases poised to spread to new areas, along with an increasing threat of diseases such as Chikungunya and the emergence of as yet unknown disease pathogens, unless researchers, disease control workers and local communities share information and communicate faster and more strategically across their professions.

Prof. ole-MoiYoi of icipe and Kenyatta University stressed the importance of tapping the expertise of local communities. “By using bed-nets and anti-malarial drugs, and by removing the human-made breeding sites of mosquitoes, communities in the Kenyan Highlands have managed to stop recurrent malaria epidemics.”

“To combat disease, we need a holistic approach that involves local communities,” ole-MoiYoi said. “We can control malaria across Africa if we can divorce ourselves from the linear thinking that looks for ‘a’ solution and adopt an integrated approach.”

The World Health Organisation (WHO)estimates that changes to the earth’s climate are already causing five million more severe illness and more than 150,000 more deaths each year. By 2030, the number of climate-related diseases is likely to more than double.

Dr. Rosemary Sang, a researcher from KEMRI, described a case study of an outbreak of Rift Valley fever that claimed the lives of 155 Kenyans in late 2006 and early 2007. The virus is transmitted from livestock to people either through handling of infected animal material or by the mosquito vectors. Sang said the outbreak, which peaked 24 December, highlights most of the critical challenges researchers and health officials face in connecting data and advanced warnings to realities on the ground.

Kenya’s Garissa District, in the remote north-eastern corner of the country, experienced heavy rains and flooding starting in mid-October 2006, resulting in standing pools of water that became breeding sites for the mosquitoes that transmit Rift Valley fever. The first veterinary interventions did not take place until mid-January 2007, almost three months after the onset of the heavy rains, 2.5 months after mosquito swarms were reported, 2 months after the first livestock and 1.5 months after the first human cases were recorded, respectively.

“We need to move up our response times to these outbreaks,” said Sang. “All of the warning signs of an outbreak were there but we weren’t able to connect the dots.”

She cites poor tele-communication and roads in the region as major challenges. “Many of these areas lie outside mobile phone networks and far from health or veterinary clinics. As animals and then people began to get sick and die, the word didn’t get out fast enough.”

In the end, however, human and animal health officials, working together, were able to save the lives of more people in the 2006/07 outbreak than in the same region in 1998, when more than 600 people died from Rift Valley fever and millions of dollars were lost in livestock trade and tourism.

“The key is predicting outbreaks before they happen and preparing high-risk areas to act quickly to reduce the impact on communities,” said Sang.
Frank Rijsberman of Google.org called on technical experts to strengthen their capacity to predict and prevent infectious diseases. That will take more and better climate, vector, human and animal data, as well as more data sharing.

“The links between the climate and health research communities across Africa need to be strengthened,” Rijsberman said. “By sharing information we can stop some disease outbreaks and dramatically shorten our response time to others – which can not only save lives but also protect communities against subsequent severe economic losses.”

Mapping the way forward
The researchers pointed to climate models and new mapping software such as Google Earth and Health Map as useful tools for integrating vast amounts of environmental, health, and poverty data. “We’re working to identify the populations of people that are most vulnerable to disease and other external shocks,” said Phil Thornton of ILRI. “That includes communities that are at high risk for malaria because, for example, they are located both far from health clinics and near to water sources. We make these ‘vulnerability maps’ publicly available so that these high-risk communities can get the support they need to respond quickly and effectively to disease outbreaks.”

Google.org environmental scientist Amy Luers said better disease responses will also require tackling diseases at their root causes. “We scientists have to do a better job of informing the public of the underlying drivers of the spread of infectious diseases. The impacts of increasing populations and environmental degradation will require institutional and governance changes put in place for a ‘one health’ approach to human, animal and environmental well being.”

“We need to prepare now to avoid future catastrophe,” says Prof. ole-MoiYoi. “We are discovering that climate variability is playing a bigger and bigger role in the spread and severity of diseases across the globe. Our survival, and that of our environment, may depend on our joining hands to understand that environment. And our roles in it.”

Conversion of pastures to croplands is big climate change threat

New study results are warning that the conversion of pasturelands to croplands will be the major contributor to global warming in East Africa.

Climate change threat

Climate change is a real and current threat to households and communities already struggling to survive in east Africa. Global climate modelling results indicate that the region will experience wetter and warmer conditions as well as decreases in agricultural productivity. However, results just released by the Climate Land Interaction Project (CLIP) forecast that there will be a high degree of variability within the region with some areas becoming wetter and others drier. This research provides evidence of the complex connection between regional changes in climate and changes in land cover and land use. The results forecast the conversion of vast amounts of land from grasslands to croplands over the next 40 years, with serious consequences for the environment.

Climate Land Interaction Project (CLIP)
CLIP is a joint research project of Michigan State University (MSU) and the International Livestock Research Institute (ILRI), supported by the National Science Foundation (NSF), exploring important linkages between land use/cover changes and climatic changes in east Africa.

CLIP researchers, together with the Kenyan Ministry of Environment and Mineral Resources, organised a workshop to present CLIP modelling results to key decision-makers in Kenya. The workshop, held in Nairobi, highlighted the policy and technical implications and options for climate change adaptations in Kenya.

CLIP researcher and professor at MSU, Jeffrey Andresen, warns that the erosion of east African grazing lands is a major threat facing Kenya and other east African countries. ‘Results of running these models indicate that the greatest amount of contribution to global warming in the east Africa region is not going to be motor vehicles or methane emissions from livestock or conversions of forests to pastures but rather conversion of pasturelands to croplands’ says Andresen.

Projected climate and land use changes in northern Kenya
Based on climate change scenarios (CLIP analysis and Intergovernmental Panel on Climate Change (IPCC) forecasts) northern Kenya will experience significant changes in rainfall and temperatures with some places becoming wetter and others drier. These changes will have dramatic impacts on ground cover and vegetation, especially the distribution and composition of grass species that form pastures for livestock and on which many people depend for their livelihoods.

Simulation models predict that areas in the remote northeast around Wajir, for example, will have greater vegetation cover and become much bushier than at present. Grazing lands are already scarce and the increasing encroachment of bush into grazing areas will create further problems for livestock keepers.

The quantity and quality of water will also be affected by the forecast changes in rainfall patterns and temperature regimes. These changes will not only affect water availability for humans and livestock but also accelerate the rate of vegetation change in different and opposite ways for different places. The ratio of tall to short grass species and closed to open vegetation, for example, depend partially on soil moisture content. It is likely that the anticipated climatic changes will greatly alter the grass ratios and these changes will then exert adverse effects on feed resources for livestock and significantly modify herd composition. In addition, traditional land management interventions, such as the use of fires and overgrazing may increase the scale, intensity and speed of these impacts.

CLIP researcher and ILRI scientist, Joseph Mworia Maitima concludes ‘Many millions of Kenyans already face severe poverty and constraints in pursuing a livelihood. But, with these projected increasing environmental stresses, they are going to become even more vulnerable.

‘It’s crucial that we now start talking about the technical and policy

Feeding tomorrow’s hungry livestock

In January 2008 ILRI shipped 4000 samples of tropical fodders and forages to Norway’s Svalbard Global Seed Vault for its offical opening today (26th February). This ‘natural freezer’ will help conserve future feed supplies.
 

Dramatic losses of plant diversity, including fodders and forages that feed livestock, are one of the greatest challenges facing sustainable development today. Soaring human populations are eroding the world’s plant genetic diversity and other natural resources. Increasing demands for human food, along with urbanization, pollution and land degradation, are squeezing out hardy fodder and forage plants that allow half a billion poor people to keep livestock. These fodders and forages are vital today. In future, they may become the only way poor livestock keepers are able to adapt to climate and other changes.

A genebank maintained by ILRI, in Ethiopia, is part of a global effort to help save food and feed plant diversity before it is too late. ILRI is conserving and studying animal feed crops to help ensure future food supplies.

ILRI and other members of the Consultative Group on International Agricultural Research (CGIAR) are storing their vast seed collections in the new Svalbard global seed vault in Norway as a safety backup. This natural freezer, located in the Arctic Circle, will preserve seeds of these plant varieties for many years. This effort is part of a global commitment under the International Treaty on Plant Genetic Resources for Food and Agriculture. The benefits are universal.
ILRI’s forage diversity project leader, Jean Hanson, says, ‘The 18,000 seed and plant samples held in trust in the ILRI genebank are tested to help scientists deliver appropriate fodders and forages for millions of poor milk and meat producers.

‘In January 2008 ILRI shipped 4000 samples of tropical fodders and forages to Norway’s Svalbard Global Seed Vault. These samples duplicate specimens from ILRI’s vast collection of African forages, the largest and most diverse in the world.’

ILRI genebank: A global public good

ILRI maintains both an active and base genebank in Addis Ababa, Ethiopia.

The active genebank is used for current research and distribution of seeds. Seeds are dried in a dehumidified drying room and packed in laminated aluminium foil bags for storage in the active genebank at 8°C. All seeds in the active collection are freely available in small quantities to bona-fide forage research workers and distributed both directly and through networks.

The base genebank is used for long-term security storage of original germplasm collections. The base genebank acts as a repository of materials that have been reasonably characterized and which may or may not have current interest or use by plant breeders. Collected materials are preserved until such time as there are enough resources available for them to be characterized and evaluated. Materials are stored in the base genebank at -20°C.

ILRI’s director general, Carlos Seré summarizes, ‘We know that weather is set to become more extreme, increasing flooding, soil erosion and salinity, droughts and other causes of land degradation.

‘Climate change will also spread diseases among livestock feed plants as well as crop plants. These changes are already increasing world food prices and threatening lives of the poor.

‘The options scientists are generating through plant genetic diversity research will help small farmers adapt quickly to their changing local environments and markets.’

‘In future, the genes scientists are investigating may provide resistance to drought, disease or salinity, not only in fodder plants but also in maize, rice and other important cereal crops’ concludes Sere.
