Africa Agriculture Geospatial Week ‘navigates change’ in Nairobi this week

Posted on June 7, 2010 by Paul Karaimu

The Africa-based International Livestock Research Institute (ILRI) this week is hosting the 2^nd Africa Agriculture Geospacial Week (AAGW) on its Nairobi campus.

The five-day event—Taking a closer look at the role of spatial information and analysis in supporting improved agricultural research and development—provides a platform for sharing ideas and knowledge on the use of geographical information systems (GIS) for agricultural development.

Meetings such as the Africa Agriculture Geospatial Week help spatial groups of all kinds to share lessons from new research and extend the reach and benefits of GIS. ILRI and other centres of the Consultative Group on International Agricultural Research (CGIAR) have been at the forefront of programs that use GIS to help farmers and herders in the developing world make more efficient use of their land and animal resources.

This year’s meeting—Navigating the change: Taking a closer look at the role of spatial information and analysis in supporting improved agricultural research and development—takes the form of a ‘GIS ShareFair’, complete with a marketplace of exhibitors and training sessions provided by ESRi, a world leader in GIS software and technology, Google, and OpenStreetMap, which provides free geographic data.

The event includes the annual meeting of the CGIAR Consortium for Spatial Information, where scientists present the results of their work. It also will launch an AGCommons service bureau and host the third gathering of WhereCampAfrica, ‘a free “unconference” for geogeographers, mobile location experts and social cartographers and all kinds of folks interested in place.’ The first WhereCampAfrica was also held at ILRI’s Nairobi campus in 2009.

In addition, a full day of the program is dedicated to presentations of new and innovative ideas by researchers, professionals and students. Awards will be given for first-time presenters (including students and young professionals), most innovative idea, most innovative medium for presentation delivery and overall best presentation.

Jointly organized by the CGIAR Consortium for Spatial Information, the CGIAR Harvest Choice program and the Agricultural Geospatial Commons (AG Commons) Program, led by the CGIAR in partnership with Spatial Development International, this week’s meeting targets professionals, researchers and students in agriculture who will come together to learn from experts in the field, share experiences and network.

Busy in Edinburgh: News from climate and systems scientist Phil Thornton

Posted on June 2, 2010 by Susan MacMillan

Philip Thornton, an agricultural systems analyst specializing in climate change and pro-poor livestock research for development issues, has worked for 14 years as a senior scientist and program leader at the Africa-based International Livestock Research Institute (ILRI). For the last 8 years, he has served ILRI as a consultant from his home in Edinburgh.

This year, Thornton was appointed leader of a research theme of a new challenge program of the Consultative Group on International Agricultural Research (CGIAR) called 'Climate Change, Agriculture and Food Security'. This CGIAR challenge program is likely this year to be transformed into one of the CGIAR's new 'mega programs'. His theme is titled 'Diagnosing vulnerability and analyzing opportunities'. Thornton will split his time equally between this new CGIAR climate change initiative and ILRI research on livestock pathways out of poverty.

As reported in the Winter 2009 issue of Agriculture for Development, the Tropical Agriculture Association last year bestowed on Thornton 'Development Agriculturist of the Year' Award 'in recognition of his contribution to international agricultural development through greater understanding of tropical agricultural systems'. The Association highlighted Thornton's prodigious work that has inform policies addressing climate change, land use and poverty alleviation.

In the current, Spring 2010, issue of Agriculture for Development, Thornton has published an article on 'Climate change and livestock keepers in developing countries: What are the prospects?'. The paper presents examples of possible impacts on livelihoods in sub-Saharan Africa 'of long-term changes in climate, and then of possible impacts of short-term changes in climate variability.' For example, Thornton reports that research indicates that 'there are widespread parts of the continent that are currently classified as mixed crop-livestock rainfed arid-semiarid systems, in which cropping is possible but may well not be in 2050'.

'All in all', writes Thornton, 'the coming decades are likely to see substantial shifts in the patterns of African cropping and livestock keeping.' The paper concludes with a summary of options for dealing with these types of changes in future.

Examples: 'Helping livestock keepers understand and deal with current levels of climate variability can provide one entry point to the problems posed by increasing variability in the future and to the options that may be needed to deal with it. For example, weather information can be used to assist rural communities in managing the risks associated with rainfall variability, and can also feed into livestock insurance schemes that are weather-indexed: policyholders are paid in response to trigger events such as abnormal rainfall or high local animal mortality rates. An index insurance scheme based on satellite imagery is currently being piloted in several areas of drought-prone northern Kenya. It may also be possible for livestock keepers to change the mix of livestock species and/or breeds that they keep, a strategy that has been practised in the past by some pastoralists in East and West Africa, for example. Longer term approaches to adaptation are also needed.'

Thornton is also an Honourary Fellow in the College of Science and Engineering at the University of Edinburgh and Editor-in-Chief of the scientific journal Agricultural Systems.

Gates entry into CGIAR: Will research technologies or innovation systems rule the day?

Posted on May 30, 2010 by Susan MacMillan

In SciDev.Net this week, Yojana Sharma describes what people see as benefits and concerns about the Bill & Melinda Gates Foundation joining the Consultative Group on International Agricultural Research (CGIAR), which supports the International Livestock Research Institute (ILRI) and 14 other centres around the world.

Prabhu Pingali, head of agriculture policy at the Foundation, acknowledges: ‘The big player in this game is obviously CGIAR. . . . The CGIAR has a much broader agenda than we do . . . .' This, says Sharma, 'is a reference to the group’s growing engagement with all aspects of improving agricultural productivity in the developing world.

Andy Hall, a researcher into rural innovation for the United Nations University in Maastricht, in the Netherlands, worries that: ‘The underlying thinking at Gates is that science can solve the problems . . . . This was the way CGIAR was in the past, and the danger is that Gates is reinventing that approach.’

Sharma concludes that: ‘The critics say that the tensions between those who favour a science- and technology-driven approach to increasing agricultural productivity, and others (such as Hall) who prefer to think in terms of promoting broader agricultural innovation systems, are at their acutest when it comes to genetically modified food.’

Which begs the question as to why so many think that a focus on agricultural technology is incompatible with a focus on agricultural innovation systems. Surely both approaches — interacting in synergy since the dawn of agriculture — are still needed.

Livestock vaccine offers lifeline to many

Posted on May 25, 2010 by MNjiru

A vaccine is being made available to save the lives of a million cattle in sub-Saharan Africa against a lethal disease and to help safeguard the livelihoods of people who rely on their cattle for their survival.

East Coast fever is a tick-transmitted disease that kills one cow every 30 seconds. It puts the lives of more than 25 million cattle at risk in the 11 countries of sub-Saharan Africa where the disease is now endemic. The disease endangers a further 10 million animals in regions such as southern Sudan, where it has been spreading at a rate of more than 30 kilometres a year. While decimating herds of indigenous cattle, East Coast fever is an even greater threat to improved exotic cattle breeds and is therefore limiting the development of livestock enterprises, particularly dairy, which often depend on higher milk-yielding crossbred cattle. The vaccine could save the affected countries at least a quarter of a million US dollars a year.

Registration of the East Coast fever vaccine is central to its safety and efficacy and to ensuring its sustainable supply through its commercialization. The East Coast fever vaccine has been registered in Tanzania for the first time, a major milestone that will be recognized at a launch event in Arusha, northern Tanzania, on May 20. Recognizing the importance of this development for the millions whose cattle are at risk from the disease, governments, regulators, livestock producers, scientists, veterinarians, intellectual property experts, vaccine distributors and delivery agents as well as livestock keepers – all links in a chain involved in getting the vaccine from laboratory bench into the animal – will be represented.

An experimental vaccine against East Coast fever was first developed more than 30 years ago at the Kenyan Agricultural Research Institute (KARI). Major funding from the UK Government’s Department for International Development (DFID) and others enabled work to produce the vaccine on a larger scale. When stocks from 1990s ran low, the Africa Union/Interafrican Bureau for Animal Resources and chief veterinary officers in the affected countries asked the International Livestock Research Institute (ILRI) to produce more and ILRI subsequently produced a million doses of the vaccine to fill this gap. But the full potential for livestock keepers to benefit from the vaccine will only be achieved through longer term solutions for the sustainable production, distribution and delivery of the vaccine.

With $28US million provided by the Bill & Melinda Gates Foundation and DFID, a not-for-profit organization called GALVmed (Global Alliance for Livestock Veterinary Medicines) is fostering innovative commercial means for the registration, commercial distribution and delivery of this new batch of the vaccine. A focus on sustainability underpins GALVmed’s approach and the Global Alliance is bringing public and private partners together to ensure that the vaccine is available to those who need it most.

Previous control of East Coast fever relied on use of acaracide dips and sprays, but these have several drawbacks. Ticks can develop resistance to acaracides and regular acaricide use can generate health, safety and environmental concerns. Furthermore, dipping facilities are often not operational in remote areas.

This effective East Coast fever vaccine uses an ‘infection-and-treatment method’, so-called because the animals are infected with whole parasites while being treated with antibiotics to stop development of disease. Animals need to be immunized only once in their lives, and calves, which are particularly susceptible to the disease, can be immunized as early as 1 month of age.

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, VetAgro Tanzania Ltd, which has been working with Maasai cattle herders in northern Tanzania. VetAgro has vaccinated more than 500,000 Tanzanian animals against East Coast fever since 1998, with more than 95% of these vaccinations carried out in remote pastoral areas. This vaccination campaign has reduced calf mortality in herds by 95%. In the smallholder dairy sector, vaccination reduced the incidence of East Coast fever by 98%. In addition, most smallholder dairy farmers reduced their acaracide use by at least 75%, which reduced both their financial and environmental costs.

Notes for Editors

What is East Coast fever?
East Coast fever is caused by Theleria parva (an intracellular protozoan parasite), which is transmitted by the brown ear tick Rhipicephalus appendiculatus. The parasites the tick carries make cattle sick, inducing high fever and lympho-proliferative syndrome, usually killing the animals within three weeks of their infection.

East Coast fever was introduced to southern Africa at the beginning of the twentieth century with cattle imported from eastern Africa, where the disease had been endemic for centuries. This introduction caused dramatic cattle losses. The disease since then 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, particularly smallholder and emerging dairy producers, as well as pastoral livestock herders, such as the Maasai in East Africa.

The infection-and-treatment immunization method against East Coast fever was developed by research conducted over three decades by the East African Community and the Kenya Agricultural Research Institute (KARI) at Muguga, Kenya (www.kari.org). Researchers at the International Livestock Research Institute (ILRI), in Nairobi, Kenya (www.ilri.org), helped to refine the live vaccine. 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 against East coast fever, with the survival of these animals raising the standards of living for many livestock keepers and their families. Field trials of the new vaccine batch, also produced at ILRI, were completed in accordance with international standards to ensure that it is safe and effective.

How is the vaccine stored and administered?
Straws of the East Coast fever vaccine are stored in liquid nitrogen until needed, with the final preparation made either in an office or in the field. The vaccine must be used within six hours of its reconstitution, with any doses not used discarded. Vaccination is always carried out by trained veterinary personnel working in collaboration with livestock keepers. Only healthy animals are presented for vaccination; a dosage of 30% oxytetracycline antibiotic is injected into an animal’s muscle while the vaccine is injected near the animal’s ear. Every animal vaccinated is given an eartag, the presence of which subsequently increases the market value the animal. Young calves are given a worm treatment to avoid worms interfering with the immunization process.

Note
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

Climate experts gather in Nairobi to seek ‘transformative’ solutions for feeding a growing and warming world

Posted on May 12, 2010 by Paul Karaimu

The livelihoods of many of the world’s rural poor are increasingly threatened by climate change. Most of these livelihoods are dependent on farming, fishing and forests. Climate change will affect and worsen the living conditions of people who are already vulnerable and food insecure, especially in developing countries. In the face of what seems an inevitable change, scientists are looking for solutions that will help poor smallholder farmers adapt their agricultural practices to cope with, and mitigate, climate change.

Through a new Climate Change Agriculture and Food Security (CCAFS) initiative, a consortium of the Consultative Group on International Agricultural Research (CGIAR) is seeking innovative approaches to address the emerging threats to global agriculture and food security. CCAFS is a 10-year initiative launched by the CGIAR and the Earth System Science Partnership (ESSP). CCAFS works to diagnose and analyse threats to agriculture and food security, to provide evidence for development of climate change policies and to identify and develop pro-poor adaptation and mitigation practices that will benefit poor farmers and urbanites alike.

In a CCAFS workshop held at the World Agroforesty Centre (ICRAF), in Nairobi, Kenya, on 4 May 2010, scientists and researchers held discussions on ways of ‘building food security in the face of climate change’. Among the key challenges to food security identified by the participants were: lack of a platform by which developing countries could share their experiences in dealing with climate change; weaknesses in presenting lessons from climate change impacts on farming; and inability to implement policies to address climatic risks to developing-country agriculture because of widespread poverty, limited human capital, and poor governance in many poor countries.

According to Achim Steiner, the Executive Director of the United Nations Environment Program (UNEP), ‘Agriculture needs to be understood within the greater context of livelihood sustainability’. Steiner believes the threat of climate change offers opportunities for agricultural development if new innovative ways of enhancing agriculture are explored. For example, agricultural practices that help communities reduce carbon emissions should be considered. ‘If we can demonstrate that a farming or production system reduces emissions, communities could be paid to develop it for expansion to solve two challenges at the same time. ‘The future of agriculture is not just in increasing production,’ the UNEP head said, ‘but in having working systems that protect the planet and that benefit those who engage in practices that protect the planet and livelihoods of the poor.

Thomas Rosswall, who chairs the CCAFS Steering Committee, noted that the ‘big disconnect [in addressing agricultural production] has been because development and global change have been addressed, researched and funded as unrelated issues’. He said ‘the approach to research needs to change so that it can link the local experiences to global needs while working with the poor to improve agricultural productivity.

Participants of the meeting agreed that ‘transformative solutions’ are needed to address agricultural challenges in the world. These solutions, they agreed, need to work with, not against, nature and they need to address conflicts of interest among farmers, countries and markets. Researchers, they said, need to focus on plant breeding and improving soil fertility. And regional decision-makers need to integrate development and climate-based polices and strategies between countries. In many countries, agricultural productivity is already being linked to climate change. In Africa, for example, an African Bio-Carbon Initiative is working to reduce the impacts of climate change on the continent’s farmers while increasing and sustaining their agricultural production. In India, environmental studies show that climate change is creating opportunities for farmers to increase their vegetable production, and thus their incomes.

According to David Radcliffe, of the European Commission, the CCAFS initiative will build understanding of the problems climate change is causing smallholder tropical farmers and will provide evidence for policies that can reduce these problems. CCAFS will focus on climate hotspots. It will pilot methods to help farmers both adapt to climate change and reduce their production of greenhouse gases, which cause climate change. Both adaptation and mitigation methods, Radcliffe said, will be needed to feed the world’s growing population while using fewer resources.

Livestock research in a new ‘framework’ for agricultural development

Posted on April 18, 2010 by Susan MacMillan

The following are highlights of a presentation made by Carlos Seré to open the annual program meeting of the International Livestock Research Institute in Addis Ababa, Ethiopia, on 15 April 2010.

The reform process of the Consultative Group on International Agricultural Research (CGIAR) is moving full speed ahead. Yesterday, the board of trustees of the International Livestock Research Institute (ILRI) agreed that we join the new CGIAR Consortium.

How do we fold ILRI’s core competencies into the more integrative programs the new CGIAR is developing?

The food price crisis triggered a reconsideration of the importance of international agricultural research. We made a serious mistake in decreasing investments in this area over the last two decades, and it is clear that we are paying the price for that mistake now. There is now renewed interest in agriculture, with many different funds being set up to support it. At the recently concluded Global Consultation on Agricultural Research for Development, in Montpellier, France, there was public recognition that the research and development system has been operating in a fractured way.

Those of us doing international agricultural research have been doing our thing, the national agricultural research systems of developing countries have been doing their thing, and so on. And even if these research organizations had been working effectively together, they have not matched themselves to programs in complementary sectors—in roads and other kinds of infrastructure, in markets, in extension services. Our challenge now is to see how all these investments can be better aligned. Our effort in the CGIAR to establish a Consortium is one part of that overall requirement for much clearer and explicit alignment of the different parts of the development process.

Why should livestock be part of the new CGIAR?

We know that livestock research can explicitly address poverty. ILRI’s research paradigm makes use of a ‘systems perspective’. And, understanding that technical solutions are only part of what poor communities and countries need, ILRI researchers have developed an ‘innovations systems mindset’.

What does ILRI bring to the new CGIAR?

Some examples in the area of 7 global issues that ILRI research addresses.

SUSTAINABLE INTENSIFICATION OF AGRICULTURAL SYSTEMS: more efficient and integrated mixed crop-and-livestock farming systems through development of improved dual-purpose food-feed crops and judicious use of available biomass.
REDUCING PASTORAL VULNERABILITY: livestock vaccines, drought insurance for herders living in drylands, policies that encourage pastoral households to diversify their income sources.
ADAPTATION AND MITIGATION STRATEGIES FOR CLIMATE CHANGE: livestock feeding regimens that increase milk yields while reducing the amounts of greenhouse gases produced; investigation of the levels of carbon sequestration in rangelands.
ENHANCED FOOD SAFEY AND MARKET ACCESS: pro-poor regulations, policies and incentives, particularly for smallholder dairy systems in East Africa and South Asia.
PREVENTION OR CONTROL OF EMERGING ZOONOTIC DISEASES: risk maps, better control of livestock disease outbreaks through participatory epidemiology.
DEVELOPMENT OF LIVESTOCK VACCINES: improved existing vaccines and development of new ones and innovative public-private vehicles for delivering them to poor livestock keepers.
7 CONSERVATION AND USE OF ANIMAL GENETIC RESOURCES: evidence to support conservation priority setting, development of reproductive technologies and other methodologies for better conservation and use of native stock in poor countries.

What are our challenges? How do we integrate all this intelligently into the new CGIAR Consortium and its Mega Programs? How do we implement gender issues into all our research work? How do we build greater capacity in our national and regional partners in developing countries? How do we build the trust needed to make the new and deeper partnerships required by the new way of operating in the new CGIAR? And how do we do a better job of quickly distilling the knowledge from our research to address urgent global issues such as climate change and emerging diseases?

International Livestock Research Institute joins new Consortium of International Agricultural Research Centres

Posted on April 15, 2010 by ILRIComms

Knut Hove, chair of the board of trustees of the Africa-based International Livestock Research Institute (ILRI), yesterday, 14 April 2010, signed an agreement on behalf of ILRI to join a new Consortium of International Agricultural Research Centres.

A ‘Resolution of the ILRI Board of Trustees Regarding the Agreement of the Consortium Constitution’, developed during the 33rd Meeting of the ILRI Board of Trustees, held on ILRI’s campus in Addis Ababa, Ethiopia, states that the ILRI Board ‘endorses the principles outlined in the Consortium Constitution and wishes to reiterate its support for the CGIAR [Consultative Group on International Agricultural Research] reform process’.

The ILRI Board noted the following in its resolution. ‘The livestock sector accounts for as much as 40 percent of agricultural gross domestic product in many developing countries and is the basis of livelihoods for hundreds of millions of poor people. Further, zoonotic diseases—i.e. diseases that spread from animals to humans—account for 70 percent of emerging diseases, and yet, in developing countries and internationally, investments in livestock research are not commensurate with its importance in the agricultural sector.

The ILRI Board is confident that the Consortium recognizes this inconsistency and that together we will be able to redress this imbalance.’

Animal agriculture can help sustain the new ‘food frontiers’ that should feed the world’s growing populations

Posted on February 23, 2010 by Susan MacMillan

Voice of America reported yesterday (‘Regulation Can’t Keep Pace with Livestock’, 22 Feb 2010) that the UN Food and Agriculture Organization (FAO) says that ‘livestock production is growing faster than our capacity to safely manage it’. A new FAO report, The State of Food and Agriculture, underscores the importance of supporting the world’s one billion poor people who depend on livestock to make their living.

What poor animal keepers need, say scientists at the International Livestock Research Institute (ILRI), is a ‘third way’ of producing milk, meat and eggs that copies neither harmful industrial-scale factory farming of animals in rich countries nor inefficient subsistence-level practices currently used to wrest a living off marginal lands in poor countries. ILRI staff argue, most recently in the world’s leading science journal, Science (‘Smart Investments in Sustainable Food Production: Revisiting Mixed Crop-Livestock Systems’, 12 Feb 2010), that more sustainable animal agriculture is particularly needed in developing countries, where livestock production is growing fast, natural resources are being degraded and lost, and small-scale mixed crop-and-livestock farmers are already feeding most of the world’s poor people. The authors of the Science paper, who come from ILRI and other centres of the Consultative Group on International Agricultural Research (CGIAR), also see this ‘third way’ of livestock production as particularly vital for the new ‘food frontiers’ of the world. These, they say, are the many farmlands currently being used to raise animals as well as to produce maize, rice and other major food crops that lie between the high- and low-potential agricultural lands of developing countries.

‘It is these relatively extensive medium-potential mixed-production farmlands that have been neglected until now,’ says lead author and ILRI scientist Mario Herrero, ‘that should now be the focus of agricultural development policymakers and aid agencies. These are the lands that are key to feeding the world’s extra 3 billion people over the next 4 decades. Click here for the Voice of America news item about the FAO study.

Special policy seminar on Millions Fed held at ILRI Nairobi campus

Posted on February 1, 2010 by ILRIComms

Learning from successes in agricultural development is now more urgent than ever. Progress in feeding the world’s billions has slowed, while the challenge of feeding its future millions remains enormous and is subject to new uncertainties in the global food and agricultural systems. Recently ILRI Nairobi had the pleasure of hosting a special policy seminar titled Millions Fed: Proven Successes in Agricultural Development, organized by The International Food Policy Research Institute (IFPRI) and CGIAR Collective Action for ESA. The key speaker was Dr. David Spielman, one of the authors of Successes in Agricultural Development: Lessons Learned from Millions Fed, a study from IFPRI, with support from The Bill & Melinda Gates Foundation, embarked on to identify and assess interventions in agricultural development that have substantially reduced hunger and poverty; to document evidence about where, when and why these interventions succeeded; to learn about the key drivers and factors underlying success; and to share lessons to help inform better agricultural policy and investment decisions in the future. Following a rigorous review process, the project ultimately identified 20 proven successes in agricultural development, several of which highlight policies, programs and investments in sub-Saharan Africa. This event presented what worked, why it worked and what we can learn from these successes. Decisions rotated around topics of importance on communicating successes in agricultural development, accumulating rigorous evidence on agricultural development and continued investment in agricultural development.

Agricultural research ‘masterplan’ unveiled

Posted on December 11, 2009 by ILRIComms

[COPENHAGEN] A “masterplan” for agricultural research and technology transfer was unveiled at the UN Climate Change Conference in Copenhagen today by the Consultative Group on International Agricultural Research (CGIAR), the world’s largest alliance of agricultural scientists.

The 45-page strategy calls for, on the one hand, action that harnesses multiple advances that the group says are waiting to be rolled out. The second strand is to boost research into longer-term solutions.

The report thus calls for an intensive effort to “speed the development and dissemination of dozens of existing improved technologies”, including hardier crop varieties and more efficient ways to manage water, trees, soils, livestock, fish and forests. These have emerged from more than 30 years of research, the group says.

“Turning this wealth of knowledge into action will create immediate benefits, bolstering food security and adapting agriculture to climate change impacts in the near term, while mitigating future impacts through reduced greenhouse gas emissions,” said Thomas Rosswall, chair of the CGIAR Challenge program on climate change, agriculture and food security.

“A quick response now will also buy us time to develop the more potent climate change solutions that will be needed 10 years from now.”

CGIAR experts also argued that the proposed adaptation fund “to enable developing countries to cope with the impacts of climate change“ should cover agriculture.

“Agriculture is part of the [climate change] problem and part of the solution,” said Rosswall.

Agriculture contributes to a third of the total global greenhouse gas emissions but is also highly vulnerable to changes in temperature and rainfall, and extreme weather events.

An International Food Policy Research Institute (IFPRI) analysis published this month (December) predicts a 10–40 per cent decline in crop yields by 2050. Food prices are projected to rise by 30–70 per cent by 2050 even without climate change and by an additional 30–100 percent due to the impact of climate change.

The CGIAR report highlighted the use of computer modelling to inform decisions about difficult trade-offs, such as those between environmental impacts and socioeconomic benefits in the global livestock sector.

The International Livestock Research Institute (ILRI) in Nairobi, for example, is modelling ways of making crop and livestock production more profitable without depleting natural resources, said Philip Thornton, senior scientist at ILRI.

It has prepared maps indicating where the environmental pressures of such production are most intense.

Computer simulations are also helping to explore the potential of crop substitution, for example, replacing beans, a major crop that is declining in many parts of sub-Saharan Africa, with the more drought-tolerant cassava.

Improving the performance of crop-livestock systems

Posted on December 7, 2009 by ILRIComms

Last week, the CGIAR System-wide Livestock Programme (SLP) held its annual planning meeting in Addis Ababa.

In this short video, John McDermott, ILRI Deputy Director General for Research introduces the SLP. He argues that its focus on the intensification of crop-livestock systems is critical: More than a billion people in developing countries are involved in these smallholder systems.

The SLP brings together 12 CGIAR centers, and, he mentions, “one of the key things we’ve been struggling with is how to improve the performance of these [crop-livestock] systems” – so people can get more income and more benefits from them; also so the systems can be more sustainable.

Reflecting on the just-completed SLP meeting in Addis Ababa, he highlights one of the major issues under discussion: how the crop biomass from these systems can be used more effectively – as food, as animal feed, and as fuel. Furthermore, how the crop residues can be fed back into the soil.

“Now we are turning our attention more to this tradeoff between whether you actually feed these residues to animals or whether some of them should stay with the soil.”

Feeding livestock, sustaining soils: Crop-livestock tradeoffs focus of SLP discussions

Posted on December 1, 2009 by ILRIComms

This week, ILRI Addis Ababa hosted a meeting of the Livestock Programme Group that steers the CGIAR’s Systemwide Livestock Programme (SLP). The Programme builds synergies between crop research and livestock research across the CGIAR.

A major discussion point at the meeting is the “pressure on biomass use in systems.”

Bruno Gerard, SLP Coordinator, explains that the group will look especially at tradeoffs in the use of crop residues – between feeding livestock or sustaining soils.
