Further unlocking the potential of maize: Dual-purpose is the new purpose of the world’s most important cereal

A September 2013 special issue of the scientific journal Field Crops Research describes research to improve, and make wider use of, dual-purpose maize (or corn) varieties, which are used for their stover — the stalk, leaves and other residue of the plant after the grain has been harvested — as well as for their grain. Among smallholder farmers in Africa and other developing regions, maize stover is a common, and critically important, supplementary feed for ruminant livestock.

The special journal issue was edited by edited by Elaine Grings, of South Dakota State University (and formerly of ILRI); Olaf Erenstein, of the International Maize and Wheat Improvement Center; and Michael Blümmel, of the International Livestock Research Institute (ILRI).

The following statements are excerpted from a synthesis paper written by the editors, which presents key ﬁndings in 12 papers about the potential for dual-purpose maize varieties to meet changing maize demands.

This special issue substantiates that dual-purpose maize varieties are technically feasible and have a large potential market, particularly in many emerging markets. The reported ﬁndings argue the case for continued investments in maize stover R&D and thus reigniting earlier dual-purpose crop research in general.

Among the findings are the following.

‘Maize — or corn (Zea mays L.) — now is the most important global cereal in terms of production reﬂecting its versatility in use, including human food, animal feed and fodder, industrial products and biofuel.’

‘Despite being a versatile crop, maize production and maize breeding efforts over time have typically had a single-purpose orientation [on improving grain yields]. . . . Even smallholders within mixed maize-livestock systems typically focus on maize grain yield . . . , with maize stover as additional byproduct and beneﬁt.’

There are prospects within the range of stover quality to increase fodder quality without compromising grain yield.

‘It is this potential of dual-purpose varieties that has reignited research interest and some of the research underlying this special issue. Indeed, despite earlier skepticism only a decade ago, substantial progress has been made in developing dual-purpose maize options for both grain and fodder purposes . . . .’

‘Maize germplasm differences in fodder quality can be exploited without compromising on grain yield.’

‘Conﬁrmation of the relatively favorable feed value of maize stover vis-à-vis other coarse cereal residues — having at least par if not better feed quality traits compared to sorghum and millet, which have been the focus of prior dual-purpose crop improvement research and have been reported to contribute substantially to gross crop production values.’

‘Conﬁrmation of being able to rely on a few key laboratory indicators . . . as good proxies for feed quality . . . as this enhances the ease of screening for feed quality traits.’

‘From a livestock nutrition viewpoint, an increase in stover quantity is only useful (unless making stover cheaper) if livestock can respond with increased intake, which is stover quality dependent.’

Sustainable intensification of agriculture in Africa: The case for mixed crop-livestock farming

Posted on September 28, 2013 by Susan MacMillan

Click to view this slide presentation made by Shirley Tarawali, director of institutional planning and partnerships at the International Livestock Research Institute (ILRI), in Nairobi, Kenya, on Thu 19 Sep 2013, at the 22 International Grasslands Congress, which was held in Sydney, Australia, 15−19 September 2013, and had some 800 participants. Other ILRI and former colleagues who developed the presentation with Tarawali are Alan Duncan, Peter Thorne, Diego Valbuena, Katrien Descheemaeker and Sabine Homann-KeeTui.

This ILRI presentation made the case for continued close integration of crop farming and livestock raising in Africa, where such integrated farming systems are key to helping small-scale food producers intensify their production levels while conserving their natural resources and protecting their environments.

Tarawali had three main messages for her audience, for which she and her colleagues provided samples of latest research work at ILRI and its partners around the world.

Don’t decouple crop intensification efforts from livestock intensification work.
Address the biomass challenge.
Improve the efficiencies of smallholder livestock production systems to reduce any harm they cause to the environment.

(1) DON’T DE-COUPLE CROP AND LIVESTOCK INTENSIFICATION

Mixed crop-and-livestock farming systems are important for feeding the world

Smallholder livestock keepers in developing countries are remarkably competitive

Livestock benefit crop production

Crop production benefits livestock

(2) ADDRESS THE BIOMASS CHALLENGE

(3) IMPROVE SMALLHOLDER LIVESTOCK PRODUCTION EFFICIENCIES TO REDUCE ENVIRONMENTAL HARM

Improve crop residues for livestock feed

Fixing fodder shortages for dairy in East Africa and South Asia, beef in West Africa, goat/sheep meat in West and southern Africa

Posted on January 15, 2013 by Susan MacMillan

In 2012, a group of researchers at the International Livestock Research Institute (ILRI) worked with partners at the World Bank, under the direction of Jimmy Smith, then a senior livestock advisor at the Bank and now director general of ILRI, in identifying investment opportunities for ruminant livestock feeding in developing countries.

Excerpts from the executive summary follow.

‘Driven by population growth, increasing demand, stricter quality and safety standards for animal source food and increasing competition for land and water resources, the livestock sector is changing rapidly. Within this changing landscape, smallholders with crops and livestock will remain the mainstay of the sector in developing countries for some decades to come.

For example, the projections in this report foresee an increase in cattle, sheep and goat populations in the mixed crop-livestock systems in the developing world from 467 million to 648 million adult cattle equivalents. However, also here, the abovementioned mega-trends and the resulting competition for feed resources imply that these systems will have to intensify to ensure an acceptable livelihood for its producers.

‘Enhancing the quality and quantity of feed, as one of the most important factors of animal production will play a critical role in this process of intensification. However, feed improvement should not be seen in isolation, but rather be assessed as part of the greater value chain, including all stakeholders. For example, investing in feed improvement without markets to sell the increased production from this investment or without an adequate feed quality control regulatory framework, would yield negative returns.

This report follows a step-by-step analytical framework that will provide the priority investments and actions in technologies, policies, and institutions.

‘As the first step in this framework, the most promising value chains, where feed-related strategies and investments are most likely to have significant impacts, have to be identified. On the basis of the key characteristics of (a) growth and market opportunities, (b) number of poor and pro-poor potential and (c) the supply constraints, in particular disease risk and feed resources availability, this report identifies first Sub-Saharan Africa and South Asia as priority areas, and then, within these areas, it identifies three commodity value chains in five regions of particularly great potential to benefit poor producers and consumers. They are:

Dairy in East Africa and South Asia
because of the expected growth in demand (including export potential), the number of poor involved (135 million), and the moderately adequate situation resource situation
Beef in West Africa
because of its potential for import substitution and potential for improvement, in spite of the resource constraints
Small ruminant meat in West Africa and Southern Africa
because of the number of poor involved (110 million) and new domestic market opportunities.

‘The framework was then used to analyze the diversity of feed types, the availability of feed sources both from within and from outside of local systems, based on informant interviews and quantitative modeling of the current situation and with projections to 2030. Detailed data for each feed type and source are available in the main text, but the general trends show:

(a) A reduction in the use of crop residue
such as straws and stovers, although at a projected between 20 and 50 percent these remain a substantial part of the daily ration of the livestock of those systems.
(b) An increase in the use of crop-by-products
(such as oil cakes and by-products of the milling industry) and concentrates, although staying in 2030 mostly below ten percent, with the exception of the South Asian dairy systems, where they would amount to 25 percent of the total diet. With such a low share of the diet, and with most products not edible for humans, these systems would not endanger global food security.
(c) An increase in the area planted for forages,
in particular in dairy systems; and (d) a sharp increase in feed procurement from the market instead of supply from the own farm.

‘Based on these projections to 2030, opportunities for feed-related investments with major positive impacts on the poor are then identified. A number of strategies, policies, technologies, and services come to light as especially promising areas for such investment in a variety of scenarios. Applying the assessment framework to each of the three value chains yielded similar results for all chains. First of all, they stress that addressing feed related issues in the context of evolving value chains requires combinations of public and private investments: policies, strategies that facilitate adoption and market engagement with reduced transactions costs such as improved access to knowledge and services for smallholder producers and other market agents together with adoption of improved feed technologies.

‘The more specific areas of improvement that warrant priority in targeting investments are:

Technological feed improving solutions include in all value chains studied
(a) more attention to research and development for feed/food crops, i.e., crops that provide both food (mostly grain) for humans and feed (mostly straws) for livestock;
(b) better ration formulation, through the introduction of feed processing and storage technologies (including micro-sizing, ensiling, etc.) and
(c) forage seed production. . .
Institutional issues include access to land and water for all smallholders, as a primary concern and as the main incentive to improve crop-residues. Effective governance on feed quality is also a common institutional issue raised. Similarly, reduction on transaction costs (both to access the feeds and to participate in product markets) is another key area for institutional investment support. In all value chains, the report strongly advocates support to Business Development Services – interpreted in the broadest sense as a key to facilitating access to feeds, markets and for reducing transaction costs. . . .
The policy concerns are more value chain specific, and include the protection against dumping of meat and milk from the OECD countries, reduction of regional tariff barriers (in particular in Sub-Saharan Africa) and lack of investment in infrastructure.

‘While for many households increasing animal numbers is perceived as attractive, there are severe environmental limitations of the extent this is possible. Policies and investment that increase per animal productivity, such as adequate ration formulation and emphasis on mineral supplementation in the feed and nutrition domain, as well as genetic and health improvement related investment will be important. However, in some areas, increased efficiency (producing the same with fewer animals, or more with the same number of animals) can also be achieved through incentive systems such as payment for environmental services.

‘Ranking those investments regarding their economic return constitutes the final step in the analytical framework, underpinning this study. The analysis shows that for an individual household, the increase in animal numbers is the most attractive option, as has also been proven in the past.

Indeed, according to FAOSTAT (2010) data, most (57 percent over the period 1990–2010) of the increased production in Sub-Saharan Africa comes from an increase in animals, and not from increased productivity per animals. This is obviously not sustainable.

‘The key challenge therefore is to increase the profitability of raising productivity per animal. As better feed utilization will be a critical factor in enhancing the profitability and hence in ensuring the long term sustainability of these system, it is therefore encouraging that in most evaluations feed improvements (and in particular the use of crop-residues) rank from the third to the fifth place. The analytical framework also provides a ranking of the importance of timing over the 2010–2030 period in which investments are made. The results show that in general a fast trajectory (i.e. transformation early in the 20-year interval) is associated with relatively higher returns accruing to investments in selected feed types, compared to a “slow” trajectory. Fast action is therefore recommended.

‘The results of this study demonstrate that the assessment framework developed could be applied readily in other systems, and at the same time provides a basis that can be further built upon.

‘This peer-reviewed World Bank report was prepared under the guidance of Jimmy Smith, formerly of the World Bank and (since Nov 2011) now serving as director general of the International Livestock Research Institute (ILRI), in Nairobi, Kenya, and Francois le Gall of the World Bank by an ILRI team consisting of William Thorpe, Derek Baker and Shirley Tarawali with Rainer Asse, Augustine Ayantunde, Michael Blummel, Oumar Diall, Alan Duncan, Abdou Fall, Bruno Gerard, Elaine Grings, Mario Herrero, Chedly Kayouli, Ben Lukuyu, Siboniso Moyo, Ranjitha Puskur, An Notenbaert, Tom Randolph, Steve Staal, Nils Teufel, Francis Wanyoike and Iain Wright.

As the cooking pot turns: Staple crop and animal foods are being ‘recalibrated’ for a warmer world

Posted on November 1, 2012 by Susan MacMillan

CGIAR has just published a really useful snapshot of the world’s major food crops, animals and tree and water resources and what is likely to happen to them in the face of climate change, the effects of which on food production will require reexamining what’s in the cooking pot, especially in regions where people already do not get enough to eat. Above, a worker on a small farm in Limuru, Kenya, pushes maize stalks (after their cobs have been harvested) through a pulverizer before feeding the stover to the cows; this is one way small-scale farmers can improve their dairy cow feeding and milk yields while reducing the amount of methane their cows generate per unit of milk produced. (Photo on Flickr by Luigi Guarino.)

CGIAR, the world’s leading international agricultural-research-for-development organization, has just done something really useful. It has published a snapshot of how climate change is likely to affect key food crops and livestock farming and natural resources in poor countries, where these staple foods and resources remain the backbone not only of food security but also of national economies. What happens to maize and wheat and rice and cattle and goats and sheep and trees and water, for example, will foretell what happens to the 1 billion people living in severe poverty today.

This snapshot summarizes the state of knowledge on 21 CGIAR crop commodities as well as on the ‘living’ livestock assets of the poor and the water and tree resources on which they depend. The study, Impacts of climate change on the agricultural and aquatic systems and natural resources within the CGIAR’s mandate, should help decision-makers at all levels prepare better for future food production on our warming planet.

The summaries, written by scientists at 14 of the 15 CGIAR centres, outline the importance of each commodity for food and nutrition security, its biological vulnerability to climate change, and the likely socio-economic vulnerability of the people affected.

The study shows points up some surprising gaps in our knowledge. For example, crops like cassava and yam, which make critically important contributions to the food security of millions of people and are highly climate-resilient, have been little studied in relation to a changing climate. We also know little about how multiple stressors of animals and plants may combine. We also have big knowledge gaps about likely impacts of climate change on weed, pest and disease complexes. We need this information to help identify and evaluate the trade-offs and synergies of particular climate change adaptation and mitigation options in different places.

A few things are already for certain. We must develop hardier varieties of maize, rice and wheat—the three main food staples around the world—quickly to avoid declines in their yields. And the common sources of protein—livestock, fish, and even soybeans—all face difficulties in adapting to the new normal.

Crops and animals till now neglected by major research initiatives, and now considered ‘old-fashioned’ by many, are likely to play an increasingly important role on global food production once again. Drought-resistant camels and goats, ‘famine foods’ such as heat-tolerant cassava and millet, and dual-purpose crops such as protein-rich cowpea (aka black-eyed peas) and groundnut that feed people and animals alike are all likely to come back to the fore in regions with drying or more unpredictable climates.

In some drying regions, smallholders will be forced to switch from crop growing to livestock raising, and/or from raising dairy cows to raising dairy or other goats. This matters to many. As the new CCAFS policy brief reports: ‘In South Asia and sub-Saharan Africa, for example, nearly one billion people living on less than two dollars per day keep livestock; two-thirds of those are women. Fisheries and aquaculture support an additional half-billion people around the world. There is no easy answer for adapting these sectors to changing climates.

But the benefits to people from eating fish and animal protein—as well as raising livestock for their livelihoods—will not evaporate as the planet warms; answers must be found in securing their continued availability.’

While the news seems grim, adaptation is possible. Recent CCAFS research in Africa found that farmers are already adapting to climate change. Some 34% of the farmers interviewed in Africa, for example, have reduced their livestock herd sizes and 48% are managing their feed resources better. The better livestock diets also lower livestock methane emissions per kilogram of milk or meat produced. On the other hand, only 25% of the farmers interviewed have begun using manure or compost to improve their soils and only 10% have begun to manage or store agricultural water.

For more information, visits the CCAFS blog page on Recalibrating food production in a changing climate—What do we know and what can be done?

Read a new policy brief by CCAFS that outlines the challenges required in feeding the estimated 9–10 billion people who will live in this world by 2050. In the brief, the need for a complete recalibration of what crops we grow and animals we raise around the world is detailed, as climate change will bring challenges in weather, water use, and increased pests and diseases of crops and animals alike.

The policy brief is based on a new CCAFS working paper. Read the paper by Philip Thornton and Laura Cramer (eds.). 2012. Impacts of climate change on the agricultural and aquatic systems and natural resources within the CGIAR’s mandate. CCAFS Working Paper 23. Copenhagen, Denmark: CGIAR Research Program on Climate Change, Agriculture and Food Security.

This report was co-edited by ILRI scientist Phil Thornton, who is a scientist at the International Livestock Research Institute (ILRI) who also coordinates one of CCAFS’ research groups. CCAFS is a global partnership launched in 2011 between the research centres of CGIAR and the Earth System Science Partnership. CCAFS facilitates and integrates thematic work across multiple CGIAR Centres and other global, regional and local partners. Its key target groups are resource-poor agricultural producers, and rural and urban consumers of food, in low-income and middle-income countries in the tropics and sub-tropics.

Philip Thornton explains about CCAFS: ‘There are many other examples of the way in which CCAFS is working across disciplines and mandates, and across temporal and spatial scales. These include linking to modelling communities from different fields such as crop modelling and global integrated assessment modelling, and partnering with organisations with skills in the development and provision of downscaled models, decision-tools and datasets that provide the necessary granularity for national and sub-national planning. As well as linking across scientific disciplines, CCAFS recognizes the need to span boundaries across research and policy domains. To link knowledge and action entails involvement of policy-makers in all stages of the research cycle, and an understanding of policy as dynamic and polycentric across the public, private and civil society sectors.’

Taking Stock: Jul 2012 round-up of news from ILRI

Posted on August 1, 2012 by Susan MacMillan

JEFF HASKINS
Last month, we at the International Livestock Research Institute (ILRI) and within CGIAR and the wider agricultural development communities grieved over the sudden loss of American media guru Jeff Haskins, who had spent six years in Africa covering African agriculture news stories for the American PR firm Burness Communications. Haskins, who had just turned 32, died at the Kenya coast on 14 Jul 2012. See online tributes to him from the ILRI News Blog (with links to 25 major news releases and 20 major opinion pieces that ILRI produced with the help of Jeff and his Burness team over the last five years), Pictures of Jeff Haskins (ILRI Pinterest Board), Pictures by Jeff Haskins (ILRI Pinterest Board), Burness Communications Blog, Global Crop Diversity Trust, CGIAR, International Center for Tropical Agriculture, La Vie Verte and Jeff Haskins Facebook page.

MAPPING ZOONOSES
Before his untimely death, Jeff Haskins in early Jul orchestrated major and widespread media coverage of a groundbreaking report by ILRI revealing a heavy burden of zoonoses, or human diseases transmitted from animals, facing one billion of the world’s poor. Some 60 per cent of all human diseases originate in animal populations. The ILRI study found five countries—Bangladesh, China, Ethiopia, India and Nigeria—to be hotspots of poverty and zoonoses. The study also found that northeastern United States, Western Europe (especially the United Kingdom), Brazil and parts of Southeast Asia may be hotspots of ‘emerging zoonoses’—those that are newly infecting humans, are newly virulent, or have newly become drug resistant. The study, Mapping of Poverty and Likely Zoonoses Hotspots, examined the likely impacts of livestock intensification and climate change on the 13 zoonotic diseases currently causing the greatest harm to the world’s poor. It was developed with support from the United Kingdom’s Department for International Development (DFID).

An opinion piece by the main author of the study, ILRI veterinary epidemiologist Delia Grace, wearing her hat as a member of the Dynamic Drivers of Disease in Africa Consortium, appeared this Jul in The Guardian‘s Poverty Matters Blog.

ILRI AWARD
Azage Tegegne, of ILRI and the Improving Productivity and Market Success of Ethiopian Farmers (IPMS) project, was awarded an honorary doctorate of science degree by Ethiopia’s prestigious Bahir Dar University.

ILRI STAFF
ILRI bid goodbye to Bruce Scott, who served ILRI as a director for 13 years, the last decade as director of ILRI’s partnerships and communications department. Bruce is moving only down the road in Nairobi, from Kabete to Westlands, where he is taking up the position of deputy director of a new initiative of Columbia University (USA): Columbia Global Centers ⁄ Africa.

ILRI & FODDER AT RIO+20
We compiled links to ILRI inputs to the Rio+20 conference, including how to ‘turn straw into gold’ with dual-purpose crop residues and, with the International Center for Tropical Agriculture (CIAT), how livestock feed innovations can reduce poverty and livestock’s environmental ‘hoofprint’.

POLICY BRIEF
ILRI produced a policy brief on ‘Preventing and controlling classical swine fever in northeast India‘.

VIDEO INTERVIEWS
We film interviewed ILRI director general Jimmy Smith on ILRI’s evolving new livestock strategy and on ILRI’s role in providing evidence about the ‘bads’ as well as ‘goods’ of livestock production, marketing and consumption. And we interviewed ILRI scientist Joerg Jores on his research results, which, as reported in Scientific American, show that the pathogen that causes cattle pneumonia (CBPP) arose with domestication of ruminants ten thousand years ago, but only ‘heated up’ and began causing disease relatively recently.

VIP VISITORS
An Australian contingent visited ILRI this month and launched a new initiative, the Australian International Food Security Centre, to improve food security in Africa. The centre, which falls under the Australian Centre for International Agricultural Research (ACIAR), will spend USD33.8 million over four years to support food production in Africa as well as in Asia and the Pacific region.

PROJECT NEWS
We reported on the signing of a memorandum of understanding by ILRI and Korea‘s Rural Development Authority (RDA) for laboratory work in Kenya, innovative platforms in an imGoats project in India and Mozambique, and training sessions on controlling zoonoses conducted by the Vietnamese members of an ILRI-led project known by its acronym EcoZD (‘Ecosystem Approaches to the Better Management of Zoonotic Emerging Infectious Diseases in Southeast Asia’).

The road back to Rio: Turning straw into gold — Crop ‘wastes’ at the heart of greener livestock development

Posted on June 18, 2012 by Susan MacMillan

Key findings were presented today on ways to enhance the value of coarse crop ‘wastes’—better termed ‘residues’—as feed for cattle, water buffalo, sheep, goats and other ruminant farm animals. The talk was given at a ‘learning event’ that is part of Agriculture Day at the Rio-20 United Nations Conference on Sustainable Development.

Carlos Seré, former director general of the International Livestock Research Institute (ILRI) now serving as chief strategist for the International Fund for Agricultural Development (IFAD), delivered this presentation on behalf of Michael Blümmel, an animal nutritionist based in ILRI’s office in Hyderabad, India, who could not make the event as scheduled.

The gist of the presentation is that wheat and rice straw, maize stover, groundnut haulms and other residues of crops that remain after their grain or pods have been harvested for human consumption are major feed resources for livestock in developing countries. Widespread and increasing shortages of arable land and water in these countries are increasing the importance of these crop residues for livestock feed, and their importance will only increase over the coming decades as human population grows and as more and more people move out of poverty and begin adding more milk and meat to their diets.

In recent years, livestock and crop improvement researchers have worked together to improve the fodder value, in terms of both quantity and quality, of crop residues at their source. They’ve done this in crop improvement programs that incorporate fodder traits in crop selection, breeding and new cultivar release criteria. Key cereals and legumes are tackled and both conventional and molecular breeding techniques are employed. Fodder traders and feed processors have started employing additional interventions to further improve the superior crop straws and stover.

The following examples illustrate the many promising findings from this collaborative fodder research.

01 Nutritionally significant variations exist in crop residue fodder value among existing cultivars that can be exploited through simple phenotyping without detriment to primary crop traits such as grain and pod yields.
As a ballpark figure, 5 percentage units in digestibility can be exploited in crop residue fodder quality without detriment to gain or pod yield in all key cereal and leguminous crops. The advantage of daily milk yield accruing from 5% difference in digestibility of basal diet in well designed ration is about 5 kg per day due to a multiplicator effect from both higher energy concentration in the diet and higher intake.

02 Simple and network-sharable food/feed/fodder nutritional phenotyping techniques have been established, such as near-infrared spectroscopy (NIRS) platforms that support whole-plant crop improvement paradigms and programs.
ILRI NIRS platforms in India and Ethiopia are being used by other research programs (e.g., the new CGIAR Research Program on Livestock and Fish) and research organizations (e.g., the International Center from Tropical Agriculture and the International Centre for Agricultural Research in the Dry Areas). Staff of national agricultural research institutions from the Congo, Eritrea, Ethiopia, Rwanda, Tanzania and Uganda have been trained in the NIRS technology and have access to network-shared NIRS equations. NIRS is increasingly being used to test for more qualitative grain traits such as lysine, tryptophan, iron, zinc and polyunsaturated fatty acids, with the aim of optimizing whole plants. This collaborative research is facilitating the analysis of 50 to 100 cultivars every day and gaining information about all their pertinent grain and crop residue traits.

03 Fodder value can be further increased through conventional crop breeding (such as recurrent selection) and molecular crop breeding (such as quantitative trait loci [QTL] identification and backcrossing).
Identification of stay-green QTLs and their backcrossing into elite sorghum varieties could increase stover digestibility by 3 to 5 percentage units while also increasing the sorghum plant’s drought resistance and water-use efficiencies.

04 In mixed crop-and-livestock agricultural production systems, the rates of adoption of new crop cultivars improved for both food and feed/fodder traits appear to be better than that for adoption of new cultivars improved for food traits only.
In a recent maize project in East Africa, farmers ranked stover traits 2.4 and grain yield 2.9 on a scale of 3. Farmers were most likely to adopt new maize cultivars that had improved stover as well as grain traits. Anecdotal evidence from groundnut adoption studies in India suggests that farmers prefer relatively small additive advantages—say 10% more pod + 10% more haulm + 10% more haulm quality—over (often theoretical) drastic increases in pod yield.

05 Participants in fodder value chains for straw and stover profit from superior straw and stover.
Price premiums for 3 to 5 percentage units in digestibility are in the range of 10 to 30%. There is higher demand for higher quality crop residues and superior sorghum stover is now regularly transported more than 400 km in parts of India. There are significant employment opportunities in harvesting, chopping, transporting and selling these crop residues.

06 Further improvement of superior straw and stover, in the form of supplementation, fortification or densification, can be done in feed processing, with productivity levels achieved from such processed but largely by-product-based feeds being four or more times greater than current levels of production.
Complete rations based on more than on 80% by-products (50–60% straws and stovers) can support 15–16 kg of milk daily in dairy buffaloes, about 1 kg live-weight gain in cattle and 120–130 g in sheep. Complete rations are suitable for smallholder farmers because the rations need not entail complex feed processing options; simply chopping and supplementing residues can suffice.

07 Increasing current yields of animals in India, such as by doubling the average daily yield of 3.6 kg of milk (across buffalo, crossbred and local cattle herds), would reduce levels of greenhouse gases dramatically, decreasing methane emission from dairy production by more than 1 million tons per year.
This is straightforward; increasing average daily milk yields in India from 3.6 to 6 to 7 kg per animal per day would reduce methane production from dairy animals relative to the same amount of milk produced by about 1 million tons per year.

In addition, there are good prospects for mainstreaming such multi-dimensional crop improvement outputs. For example, new CGIAR Research Programs (such as those on maize, rice, dryland cereals, and grain legumes) have already adopted the approach and have incorporated fodder value as high-priority traits in these crops.

The road back to Rio: ‘LivestockPLUS Learning Event’ shows how better feed reduces poverty AND livestock ‘hoofprints’

Posted on June 18, 2012 by Susan MacMillan

Several hundred people in Rio de Janeiro today will be discussing and debating a topic not often included in high-profile meetings. The topic is how we can use improved livestock feed to reduce both poverty and climate change.

The discussions today will take place at one of 13 ‘learning events’ that are part of an Agriculture and Rural Development Day at the Rio+20 United Nations Conference on Sustainable Development. Staff from CGIAR Centres are helping to organize and are participating in events throughout this day.

Given that the key messages of this particular learning event run counter to much current thinking about livestock, the participants will share and discuss scientific evidence that demonstrates the benefits of improved feeding practices, particularly their potential for contributing significantly to climate change mitigation while improving livestock production.

Messages
On the table today are both fodders, coarse foods composed of entire plants or the leaves and stalks of cereal crops, and bulky grass or hay forages. The learning event, titled ‘LivestockPlus—How can sustainable intensification of livestock production through improved feeding practices help realize both livelihood as well as environmental benefits?’, will deliver the following three fundamental messages.

New feeding practices can increase livestock production while decreasing its ecological ‘hoofprint’

New livestock feeding practices, like the use of improved dual-purpose crops and high-quality forages, offer significant potential for sustainable intensification of agricultural production to enhance livelihoods while also reducing livestock’s ecological ‘hoofprint’.

Improved forages, like forests, will capture carbon

Improved tropical forages offer the further advantage of sequestering large amounts of carbon—on a scale similar to that of forests—with the possibility of reducing emissions of nitrous oxide and methane per unit of livestock product. There is evidence that the potential of sown forages to sequester carbon (assuming good pasture and livestock management) is second only to that of forests and that sown forages could realize 60–80% of agriculture’s total potential to mitigate climate change.

Better feeding practices will allow mixed crop-livestock farmers to produce more food more sustainably

If widely applied by the vast army of ‘mixed’ smallholder farmers, who raise livestock as well as grow crops, and who are the mainstay of global food security, improved livestock feeding practices could deliver huge increases in food production at reduced environmental cost against a background of rising livestock production and consumption in the developing world.

Evidence
The result of numerous global initiatives and extensive testing, this work offers practical examples of how improved feeds can raise the production and incomes of smallholder farmers. Superior forage grasses widely adopted in Latin America, for example, already generate up to USD4 billion in Brazil alone. And improved tropical forages have also been adopted widely in Southeast Asia since the start of their promotion in 1995. A recent review indicates that continued adoption of improved feeds, including sown forages, could significantly reduce greenhouse gases on a global scale, while enhancing the livelihoods of the one billion people dependent on livestock-cropping systems.

What remains to be done
To scale up these improved feed resources so that they contribute to a transformed food system, we need more precsie understanding of the impacts of livestock on climate change, with the impacts differentiated by specific livestock-cropping systems, as well as of the potential for improved feeding practices to mitigate climate change. To make livestock and crop production in the tropics more climate friendly through improved feeding practices, smallholders must be given stronger incentives to market their livestock products and to sequester carbon through improved land management. Smallholders might be encouraged to adopt sown (and carbon-storing) forages, for example, through schemes instituted to pay them for the environmental services they provide.

What could be achieved
With donor support for research to obtain conclusive data and to provide policymakers with support for their decision-making, a functional system for implementing the LivestockPlus concept and associated strategies could be available within the next 5–6 years.

The program for this learning event
The program for this learning event includes a keynote presentation on the role of forages and livestock production in mitigating greenhouse gas emissions by CIAT soil scientist and agroecologist Aracely Castro; this keynote will be followed by three short case-study introductions on the following topics.

Carbon sequestration in livestock production for climate change mitigation: Implications for policy development in Brazil, presented by Embrapa beef cattle researcher Davi José Bungenstab.

Livestock production and climate change in sub-Saharan Africa and Asia: Technical innovation for environmental and livelihood benefits, presented by Carlos Seré, former director general of ILRI and now chief strategist for IFAD (note: Seré is speaking on behalf of ILRI animal nutritionist Michael Blümmel).

Climate-smart silvopastoral systems for a green livestock economy, presented by CATIE director Muhammad Ibrahim.

These case study presentations will be followed by parallel group discussions on each of the three cases to answer such questions as:
What are the main research findings that support the technological or policy innovation, including evidence of livelihood and environmental benefits?
What were key lessons learned from the research leading to this innovation?
What are the requirements for scaling it up?

The session will close with a moderated panel discussion in plenary with the keynote speaker and case study presenters.

Institutions involved
CATIE is a regional centre of excellence based in Costa Rica that works on solutions for the environment and development in rural communities in Latin America and the Caribbean.

CIAT, the International Center for Tropical Agriculture, based in Colombia, works to increase the eco-efficiency of agriculture to reduce hunger and poverty and to improve human health in the tropics.

EMBRAPA is the Brazilian Agricultural Research Corporation, which works for the sustainable development of Brazilian agribusiness.

ILRI, the International Livestock Research Institute, based in Africa, works to reduce hunger, poverty, ill health and environmental degradation through enhanced livestock systems for poor people in the developing world.

Presenters at the event
This learning event will be chaired by Elcio Guimarães, who is director of research for Latin America and the Caribbean at the International Center for Tropical Agriculture (CIAT). Discussions at the session will be summarized by Nathan Russell, a key organizer of this session who leads corporate communications work at CIAT. One of the three scheduled case study speakers, Michael Blümmel of ILRI, is unable to attend; his presentation will be made by Carlos Seré, former director general of ILRI and now chief strategist for the International Fund for Agricultural Development (IFAD).

Milk markets as ‘the great equalizer’ in East Africa?

Posted on May 26, 2012 by Paul Karaimu

A dairy farmer in Kenya. Incorporating informal milk producers and traders into the country’s formal milk markets is improving the welfare of the poor (photo credit: Flickr/Gates Foundation).

Remarkably, more than 80 per cent of the milk produced and sold in Kenya comes from small-scale players, typically farmers raising one or two dairy cows on small plots of land and milk hawkers plying their trade on bicycles on streets and in villages.

The fast-growing dairy sector in this East African country could help tens of thousands of people climb out of poverty. But this will require supporting small-scale milk producers and traders in gradually entering the country’s formal milk markets.

Until recently, Kenya’s informal milk producers and traders were harassed rather than supported by officials because they were unregulated and were perceived to be a threat to public health.

A chapter in a new book, Towards priority actions for market development for African farmers, describes how Kenya’s small milk producers and sellers are being integrated into formal dairy markets. Authors Amos Omore and Derek Baker, from the International Livestock Research Institute (ILRI), say that what was needed was ‘recognizing and embracing’ the big contributions of dairy’s informal producers and traders and the potential role played by the informal milk markets in fighting poverty. According to the researchers, the removal of policy barriers to allow price-based competition to govern milk trade is enabling this informal dairy industry to significantly improve the welfare of the poor.

Using lessons and examples from a highly collaborative research and development Smallholder Dairy Project, the authors point out that training and certifying small-scale milk traders helps draw the informal milk producers and traders into a more ‘formal’ trading environment. This training also raises consumer confidence by improving and guaranteeing the quality of milk produced for market. With this training, which also teaches business and entrepreneurial skills, the small market players are increasing their incomes as well as milk consumption among poor communities.

‘This dairy project was instrumental in bringing about “mind-set and policy changes” and an impact on the profits made by milk producers in Kenya,’ say Omore and Baker. ‘It also provided a new model of incorporating these small producers into the formal sector.’

Carried out between 1997 and 2005, the Smallholder Dairy Project was led by Kenya’s Ministry of Livestock and Fisheries Development and implemented by ILRI and the Kenya Agricultural Research Institute. It was funded by the UK Department for International Development.

Kenya’s dairy industry, one of the largest in Africa, is supported by over 1.8 million mostly small-scale cattle producers who at the time of implementing the Smallholder Dairy Project supplied over 86 per cent of the country’s milk through direct milk sales from producers to consumers and from dairy farmer groups and over 40,000 small-scale farmers.

The chapter argues that small-scale milk traders trained and certified by the Kenya Dairy Board improved their hygienic practices in milk production and handling. These efforts have brought about ‘direct and sustainable benefits’ for dairy-dependent livelihoods, including making more milk available in the market and higher prices. More licensed small-scale vendors now to operate in the country contributing to more competitive prices that encourage farmers to produce more milk.

The success of the dairy project in mainstreaming Kenya’s the informal milk producers into Kenya’s dairy industry led to a revision of the country’s licensing processes, which then began to start recognizing these informal milk sellers. A 2004 dairy policy change paved the way for significant increases in the number of traders adopting milk testing methods, greater enforcement and compliance in milk quality control and an on-going regional harmonization of dairy policies and standards aiming to transform informal milk markets in Rwanda, Tanzania and Uganda along the lines of the Smallholder Dairy Project in Kenya.

For the tens of thousands of small milk producers in Kenya, these policy changes have made a great difference. Evidence suggest that without the Smallholder Dairy Project, these benefits would have taken another two decades to come to small-scale dairy sector players.

Making Asian agriculture smarter

Posted on April 20, 2012 by Susan MacMillan

Last week, coming on the heels of a Planet Under Pressure conference in London, which set out to better define our ‘planetary boundaries’ and to offer scientific inputs to the Rio+20 United Nations sustainable development conference this June, a group of leaders in Asia—comprising agriculture and meteorology chiefs, climate negotiators and specialists, and heads of development agencies—met to hammer out a consensus on ways to make Asian agriculture smarter.

The workshop, Climate-smart agriculture in Asia: Research and development priorities, was held 11–12 April 2012 in Bangkok. It was organized by the Asia-Pacific Association of Agricultural Research Institutes; the CGIAR Research Program on Climate Change, Agriculture and Food Security; and the World Meteorological Organization.

This group set itself three ambitious tasks: To determine the best options (1) for producing food that will generate lower levels of greenhouse gases, which cause global warming; (2) for producing much greater amounts of food, which are needed to feed the region’s rapidly growing and urbanizing population; and (3) for doing all this under a changing climate that, if farming and farm policies don’t change, is expected to reduce agricultural productivity in the region by anywhere from 10 to 50 per cent over the next three decades.

The workshop participants started by reviewing the best practices and technologies now available for making agriculture ‘climate smart’. They then reviewed current understanding of how climate change is likely to impact Asian agriculture. They then agreed on what are the gaps in the solutions now available and which kinds of research and development should be given highest priority to fill those gaps. Finally, they developed a plan for filling the gaps and linking scientific knowledge with policy actions at all levels.

On the second of this two-day workshop, the participants were asked to short-list no more than ten key areas as being of highest priority for Asia’s research and development communities.

This exercise tempted this blogger to suggest ten suitable areas in the livestock sector.

(1) Lower greenhouse gas emissions from livestock through adoption of improved feed supplements (crops residues) that reduce greenhouse gas emissions.

Planet under pressure / Bits and pieces

Posted on April 9, 2012 by Susan MacMillan

This 6-minute animated film explains how we can feed the world by 2050; it was produced by CCAFS and first shown at the Planet Under Pressure conference in London, Mar 2012.

In this last posting from the International Livestock Research Institute (ILRI) about the recent Planet Under Pressure (PUP) conference (London, 26-29 Mar 2012), we highlight a few of our favourite things.

Animated film on a ‘safe operating space’ for food security to 2050
The Commission on Sustainable Agriculture and Climate Change launched a short animation that illustrates key actions needed for a ‘safe operating space’ for food security in 2050. An integrated approach must balance how much food we produce, how we adapt to a changing climate and how much agriculture contributes to further climate change. The film offers a summary of steps needed to meet food needs and stabilize the climate. It is short (6 minutes) and very good. Watch it here: How to feed the world in 2050: actions in a changing climate, Mar 2012.

Report from the Commission on Sustainable Agriculture and Climate Change
Efforts to alleviate the worst effects of climate change cannot succeed without simultaneously addressing the crises in global agriculture and the food system and empowering the world’s most vulnerable populations. Many of these issues have commonly been ‘stovepiped’ into different scientific disciplines, economic sectors, policy processes and geographic regions. The Commission on Sustainable Agriculture and Climate Change was set up in 2011 to come up with an integrated approach for dealing with these urgent, globally interconnected challenges. Their final report and summary for policymakers, launched at PUP, offer concrete actions to transforming the food system to achieve food security in the face of climate change.

Intensifying agriculture within planetary boundaries
Deborah Bossio, a soil scientist who in Feb 2012 took up the position of research area leader of the Tropical Soil Biology and Fertility Institute of the International Center for Tropical Agriculture (CIAT-TSBF), led a session on ‘Intensifying agriculture within planetary boundaries’. One of the panel speakers was Kate Brauman, one of the authors of a paper published in Nature last October, Solutions for a cultivated planet, led by Jon Foley, director of the Institute on the Environment at the University of Minnesota, and co-authored by many others.

‘We are adding 2 billion people to the world by 2050’, Brauman said, ‘by which time we’ll need to double food production. We need to do this in a sustainable way; we need to do this while keeping a world we’d like to live in. But agriculture’s environmental footprint is big: Agriculture uses 40 per cent of the Earth’s land surface, is responsible for 70 per cent of all water use, and generates about 35 per cent of the greenhouse gases that are warming our Earth, mostly deforestation.’

We have a three-part challenge’, Brauman said. ‘Feed everyone today. Double food production by 2050. And do that in a sustainable way.’

The ‘Solutions for a cultivated planet’ paper offers a 5-part solution:
(1) Slow agricultural expansion: Most expansion will give us relatively small gains at very great environmental costs.
(2) Close yield gaps to increase agricultural productivity: Increase production through intensification where ag systems are already in place
(3) Improve resource efficiency of agriculture: Grow smarter by noting where there is excessive and insufficient nitrogen sources, water sources, etc., and get more bang for our buck.
(4) Close diet gaps: Only 60% of global production is directly consumable, with much going to animal feed, etc.
(5) Reduce food waste, whether stored on poor farms or thrown away in the refrigerators of the rich

‘There is no single way’, Brauman concluded. ‘We need to use all five of these strategies. It can’t be about organic vs commercial, but about both. We’ve only got one planet. We really have to do this right.’

Justin Gillis, in the New York Times Green Blog (Deep thinking about the future of food), points out what is special about Foley’s study: ‘The group finds, as others have before them, that the challenge of doubling global food production in coming decades can probably be met, albeit with considerable difficulty. The interesting thing to me about the analysis is that it doesn’t treat any of the problems confronting the food system as superior to the others—it treats the environmental problem, the supply problem and the equity problem as equally important, laying out a case that they all need to be tackled at once.’

CGIAR Research Program on Water, Land and Ecosystems
A CGIAR Research Program on Water, Land and Ecosystems was launched at PUP. This multi-institutional program is led by the International Water Management Institute (IWMI), recently named this year’s Stockholm Water Prize Laureate. The new program embodies a ten-year commitment to bring about a radical transformation in the way land, water and natural systems are managed. ILRI is one of its 11 CGIAR partners. The new research program is the latest in a series of initiatives designed to promote more joined-up-thinking on agricultural research for development at CGIAR, the world’s largest consortium of agricultural researchers. The program’s newly appointed director, Simon Cook, says that more effective, equitable and environmentally sensitive pricing of natural assets like water needs to be mainstreamed. And the fragmented ways in which river basins are managed—with different sectors, such as agriculture, industry, environment and mining, considered separately rather than as interrelated and interdependent—needs to be fixed. ‘A re-think is needed’, Cook says.

Biomas under pressure
ILRI scientist Diego Valbuena gave a handsome presentation on Biomass pressures in mixed farms: Implications for livelihoods and ecosystems services in South Asia and sub-Saharan Africa at a ‘Food security’ session on the first day of PUP. The work behind this presentation was conducted by members of the CGIAR Systemwide Livestock Programme. If the planet is under pressure (and it is), the pressure on biomass might serve as its poster child. Most of the world’s small-scale farmers mix crop growing with livestock raising, with each activity supporting the other. One of the major synergies exemplified by kind of integrated farming is the use of crop residues—the leaves, stalks and other remains of crops after their grain or legumes have been harvested—for feeding livestock as well as for conserving soil nutrients (through mulching), for fuel and for construction. As agricultural systems intensify, the pressures on the biomass available increase. This research is identifying optimal ways of using crop residues in different regions and circumstances.

And the one that got away
One session that never happened was on ‘Livestock and global change: A dialogue on key pressures and potential solutions’. To have been led by systems analysts Mario Herrero, of ILRI, and Philip Thornton, of ILRI and the CGIAR Research Program on Climate Change, Agriculture, and Food Security (CCAFS), and to have included on the panel ILRI veterinary epidemiologist Delia Grace and ILRI partner Tara Garnett, who leads the Food Climate Research Network at the University of Surrey, this session was cancelled due to an emergency. The session was sorely missed since there was a dearth of discussion at PUP on livestock issues, which these scientists and others believe need to have a higher profile at such events. What the session would have covered:

Due to the magnitude of the livestock sector, the pressures it exerts on the world’s natural resources, and the multiple socio-economic benefits it provides, this session will span across many subject areas of interest (food security, poverty reduction, vulnerability, greenhouse gas emissions mitigation, competition for biomass, land, water, and others). The topic is central to developing-country agendas, which often have large livestock sectors and people depending on them.’

Straw matter(s) in Nepal

Posted on February 21, 2012 by Susan MacMillan

Dairy woman Nimala Bogati feeds her improved dairy cows green fodder. An ILRI-CSISA project on the Indo-Gangetic Plains of Chitwan District, in south-central Nepal, began in Sep 2010. Project staff are introducing residue-based feeding strategies supplemented with green fodder and concentrates to increase cattle and buffalo milk production (photo credit: ILRI/Susan MacMillan).

Starting in 2010, feed‐related aspects of dairying in two municipalities of Chitwan District in south-central Nepal have been investigated by staff members from the International Livestock Research Institute (ILRI) and a local Nepali non-governmental organization called Forum for Rural Welfare and Agricultural Reform for Development (FORWARD). This study set out to gain an understanding of the overall dairy production system in this district, with a particular focus on the livestock feeding strategies employed by farmers, and to identify key areas of the feeding strategy that could be altered to improve livestock productivity. A feed assessment tool called FEAST—a questionnaire that combines informal group discussions with structured interviews of key farmer informants—was used to rapidly assess on‐farm feed availability in a smallholder context.

FORWARD’s Deep Sapkota and ILRI’s Arindam Samaddar confer on a visit to a smallholder dairy producer in Gitanagar, Chitwan District, south-central Nepal (photo credit: ILRI/Susan MacMillan).

Project staff from ILRI and FORWARD selected the municipalities of Gitanagar and Ratnanagar for this study because these sites were to become part of projects conducted by a multi-institutional Cereal Systems Initiative of South Asia (CSISA) in Nepal.

Farmers in this area generally have very small plots of land, averaging just 0.24 hectares, from which they produce a wide variety of crops. Rice, maize and wheat are the dominant cereal crops here. Goats and dairy cattle, predominately Holstein-Friesian and Jersey, are the main livestock kept. Some households also keep dairy buffaloes and poultry.

Dairying and other livestock activities contribute 63% of household income, cropping the remaining 37%.

Crop residues (most of which until recently were purchased) are the primary component of the feed for the farm animals and are relied on throughout the year.

Purchased concentrate feeds such as wheat bran and commercially mixed rations provide a significant portion of the dietary metabolizable energy and crude protein.

ILRI has been working with FORWARD for just over one year to improve understanding in these farming communities of key animal health, nutrition and reproduction concepts, so that the farmers can reduce the costs of their milk production, with purchased feed being the main cost.

Goats are the most popular livestock species kept within the area. Eighty percent of households keep 2–3 goats, which are used to fulfil household meat requirements and/or sold at irregular intervals for slaughter. Half the households here keep improved dairy cows, primarily Holstein-Freisian and Jersey, with each household keeping some 2–3 cows. About 10% of the households maintain local buffalo, and 5% improved buffalo such as Murrah, for milking, with each household keeping 1–2 animals. Local cows and buffalo are the cheapest dairy animals available, costing about 10,000Rs (USD$141) and 30,000Rs (USD$423) per head respectively. Improved cows and buffalo are available for 80000–90000Rs (USD$1128–USD$1269) per head. Dairy animals in this area produce approximately 3141 litres of milk per head per year, with sales of milk generating 249446Rs (USD$3519) per household annually.

The dairy animals are usually maintained in purpose built sheds in close proximity to the household and stall fed throughout the year. The shed will generally only have temporary walls that are erected during winter months to keep the animals warm. During summer months, the walls are removed to allow air to circulate around the animals to keep them cool.

Notes
About FEAST
Feed for livestock is often cited as the main constraint to improved productivity in smallholder systems. Overcoming this constraint often seems an elusive goal and technical feed interventions tend to adopt a scattergun or trial and error approach which often fails to adequately diagnose the nature of the feed problem and opportunities and therefore the means to deal with problems and harness opportunities. The purpose of the Feed Assessment Tool described here is to offer a systematic and rapid methodology for assessing feed resources at site level with a view to developing a site-specific strategy for improving feed supply and utilization through technical or organizational interventions. Output from FEAST consists of a short report in a defined format along with some quantitative information on overall feed availability, quality and seasonality which can be used to help inform intervention strategies. The tool is aimed at research and development practitioners who are working in the livestock sector and need a more systematic means of assessing current feed-related strategies and developing new ones.

About CSISA
The Cereal Systems Initiative for South Asia (CSISA) applies science and technologies to accelerate cereal production growth in South Asia’s most important grain baskets. CSISA works in partnerships in 9 intensive cereal-production ‘hubs’ in Bangladesh, India, Nepal and Pakistan to boost deployment of existing crop varieties, hybrids, management technologies and market information. CSISA is funded by the Bill and Melinda Gates Foundation and the United States Agency for International Development and conducted by the International Maize and Wheat Improvement Program (CIMMYT), the International Food Policy Research Institute (IFPRI), ILRI and the International Rice Research Institute (IRRI).

ILRI DAIRY FEED INTERVENTIONS IN SOUTH ASIA
Last September, ILRI held a workshop in Dehradun, northern India, to develop a tool for feed technology screening and prioritization. Last December, ILRI and national research institutions and NGOs from Bangladesh, India and Nepal conducted dairy feed experimental trials and demonstrated better use of crop residues for feeding to their dairy cows. Thirteen participants from four sites in Haryana, India (National Dairy Research Institute); Bihar, India (Bihar Veterinary College, Sarairanjan Primary Agricultural Cooperative Society); Chitwan, Nepal (Forum for Rural Welfare and Agricultural Reform for Development); and Dinajpur, Bangladesh (Bangladesh Livestock Research Institute, Cooperative for Assistance and Relief Everywhere) shared their results of the feed intervention trials and related training activities.

ETHIOPIAN LIVESTOCK FEEDS PROJECT (ELF)
This week (21–22 Feb 2012), an inception workshop for an Ethiopian Livestock Feeds Project (ELF) is taking place at ILRI’s campus in Addis Ababa, Ethiopia. The project involves a short scoping study that will be used to help further develop and test rapid livestock feed assessment methods such as FEAST and Techfit. This work is funded by the Australian Centre for International Agricultural Research.

‘Feed the Future’: Connecting ALL the (agricultural research) dots in the Ethiopian highlands

Posted on January 31, 2012 by Susan MacMillan

Sustainable intensification of crop-livestock systems to improve food security and farm income diversification in the Ethiopian highlands: Project Design Workshop—Project Outline and concepts

Watch and listen to a 17-minute (audio-enhanced) slide presentation made by ILRI’s Shirley Tarawali on the ‘Sustainable intensification of crop-livestock systems to improve food security and farm income diversification in the Ethiopian highlands,’ 30 Jan 2012.

Can scientists make the whole of agricultural research for development greater than the sum of its parts? That’s the aim of a new initiative starting this year in three regions of sub-Saharan Africa.

As part of an American ‘Feed the Future’ initiative to reduce hunger in sub-Saharan Africa, the US Agency for International Development (USAID) is supporting three agricultural research projects aiming to help Africa’s smallholders intensify their production systems and do so in ways that are sustainable.

These projects will be conducted in three regions of Africa: Sustainable intensification of cereal-based farming systems (1) in the Sudano-Sahelian Zone of West Africa and (2) in East and Southern Africa, both led by the International Institute of Tropical Agriculture (IITA), based in Ibadan, Nigeria; and (3) Sustainable intensification of crop-livestock systems to improve food security and farm income diversification in the Ethiopian highlands, led by the International Livestock Research Institue (ILRI).

These three African agricultural intensification projects were all launched this year (2012) with design workshops. A wiki has information on the three workshops, including their agendas and outputs.

The design workshop for the project in the Ethiopian highlands has just started at ILRI’s campus in Addis Ababa. ILRI’s director for its People, Livestock and the Environment Theme, agronomist Shirley Tarawali, who will soon take up a new position as ILRI’s director of institutional planning, gave a 17-minute slide presentation on the project (above).

Tarawali said in her presentation that the project is ambitious to fix the disconnect between separate research projects on separate agricultural topics (livestock, cereals, water, and so on) by identifying and then pulling together the best research outputs from the separate research projects. Such outputs include, for example, the identification of legumes and cereals that will better feed livestock as well as people (and sometimes soils as well); ways to make more strategic use of scarce fertilizers and optimal combinations of organic (manure) and inorganic (synthetic) fertilizers; and more efficient ways to use water resources.

Add these kinds of useful products together and we could benefit whole farming systems,’ says Tarawali.
