Researchers say that poor countries can protect both livestock livelihoods and environments by promoting measures such as sustainably intensifying mixed crop-and-livestock farming, paying livestock keepers for the ecosystem services they provide, helping pastoralists diversify their sources of income and managing the demand for livestock products.

Researchers from the International Livestock Research Institute (ILRI), the Food and Agricultural Organization of the United Nations and the Animal Production Systems Group at Wageningen University, in the Netherlands, report in a proceedings published last November (2010) that there are ‘significant opportunities in livestock systems for improving environment management while also improving the livelihoods of poor people.’

The publication, titled The Role of Livestock in Developing Communities: Enhancing Multifunctionality, was co-published by the University of the Free State South Africa, the Technical Centre for Agricultural and Rural Cooperation and ILRI. The authors say that even though livestock production is already harming some environments, with such damage likely to increase in some regions in coming years due to an increasing demand from rapidly expanding populations in the developing world, new research-based options for livestock production can help improve both the livelihoods and environments of hundreds of millions of very poor people who raise farm animals or sell or consume their milk, meat and eggs.

The researchers propose shifting the debate on livestock and environment from one that focuses solely on the negative impacts of livestock production to one that embraces the complexity of livestock ‘goods’ and ‘bads’, particularly in developing countries, where livestock serve as a lifeline to many poor people.

The researchers say a good understanding of the environmental impacts of livestock production depends on distinguishing these impacts by region and production system and by addressing environmental problems along with problems of food insecurity and inequity.

The authors, who include ILRI scientists Mario Herrero, Phil Thornton, An Notenbaert, Shirley Tarawali and Delia Grace, recommend making a ‘fundamental shift’ in how demand for livestock products is seen and in adapting production systems to meet this demand. They suggest, for example, that policymakers consider ways of reducing demand for livestock products in (mostly industrialized) countries where (1) people are damaging their health by consuming too much meat, eggs and milk and (2) intensive ‘factory’ farming is damaging the environment.

The scientists also recommend finding ways of improving water management in livestock production. Recent findings show that livestock water use represents 31 per cent of the total water used for agriculture. The authors report that ‘in rangeland systems, water productivity can be improved by better rangeland management, which has the potential to reduce water use in agriculture by 45 per cent by 2050.’ Another promising idea is to begin paying livestock farmers for the rangeland water purification and other ecosystem services they maintain for the good of the wider community.

To reduce greenhouse gases from livestock systems, the authors recommend that efforts be put in place to intensify production systems in developing countries to produce more livestock products per unit of methane gas. ‘We need to provide significant incentives so that the marginal rangeland areas, often rich in biodiversity, can be protected for the benefit of farmers.’ Other options for reducing livestock-associated greenhouse gasses include improving animal diets, controlling animal numbers and shifting the kinds of breeds kept.

Although diseases transmitted between livestock and people also need to be addressed by research, the book notes that the ‘net effects of livestock on human health are positive,’ particularly due to livestock’s role in providing nourishing food for the poor and the contribution livestock herders make to regulating vast rangeland ecosystems, with their wildlife populations, which often helps prevent animals diseases from spilling over to human populations. Better use of disease control methodologies and investments will also help prevent the spread of these diseases.

The authors acknowledge that such changes in the way that livestock production is viewed will require a ‘subtle balancing act’ and commitments by a wide range of players in the scientific, development and policymaking communities. But without a more nuanced understanding of livestock production in the face of hard trade-offs between livestock and the environment, we could jeopardize the livestock livelihoods of many of the world’s ‘bottom billion’.

Food-feed crops research: A synthesis

Posted on by

In December 2010, a special issue of Animal Nutrition and Feed Technology focuses on the fodder quality of crop residues and how this can be improved through the close collaboration of crop and livestock scientists in multi-dimensional crop improvement programmes.

Over the next two decades, rapid urbanization and rising incomes in the developing world will continue to feed an on-going livestock revolution. In India, this boom in the production of animal products will be driven by a demand for milk that is projected to increase by more than 80 million tons in 15 years.

Smallholder livestock producers will have new opportunities to raise their incomes on the back of this increasing demand, particularly the vulnerable communities occupying dry, marginal and remote lands that rely most heavily on their animals.

Feed scarcity and resulting high feed costs are one of the major constraints and threats to higher benefits from livestock otherwise offered by the rising demand for livestock products. New strategies for improving feed resources are urgently needed, but they need to take into account the increasing scarcity of the natural resource base, particularly of arable land and increasingly water.

Crop residues are the single most important feed resource in India, and the national feed resource scenarios predict that their importance for livestock feeding will further increase. In several parts of India, weight for weight, crop residue prices are now approaching, and sometimes even exceeding, half the prices of their grains.

Crop residues do not require specific land and water allocations, since these are required in any case for the production of grains. Unfortunately, the fodder quality of crop residues is often low, and in the past decades, efforts have been invested in upgrading the feeding value of crop residues (implicitly from cereals since leguminous residues can have excellent fodder quality) through chemical, physical and biological treatments.

However, these approaches have seen little adoption by farming communities. A different paradigm has been developed in this this special issue of Animal Nutrition and Feed Technology, namely, the improvement of crop residues at source through close collaboration of crop and livestock scientists in multidimensional crop improvement programs. Until recently, fodder traits of crop residues were largely ignored in crop improvement, although farmers were traditionally aware of differences in the fodder quality of crop residues even within the same species. Farmers’ perception of crop residue fodder traits could effect the adoption of new cultivars, resulting sometimes in the rejection of new cultivars that have been improved only for grain yields.

In response, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and the International Livestock Research Institute (ILRI) together with their partners from the Indian Council of Agricultural Research (ICAR) initiated several multidisciplinary research projects to create crop cultivars that better match the need of farmers, particularly in mixed crop-livestock systems which are dominant in many parts of the developing world.

The fundamental issues explored in these collaborative projects, and expounded in this special issue, are: (1) availability of livestock nutritionally-significant cultivar-dependent variation in crop residue fodder quantity and quality; (2) relationships between crop residue fodder traits and primary food traits and possible trade-offs between the traits; (3) technologies for quick and inexpensive phenotyping of large set of samples for simple fodder quality that are well correlated with actual livestock productivity; (4) breeding techniques for further genetic enhancement towards food-feed traits; and (5) upgrading crop residue fodder in value chains through densification and fortification.

These valuable contributions serve as eye-openers to researchers and present a strong case for further strengthening such collaborations between national and international crop and livestock institutions. More importantly, they pave the way for expanding work on the promising approach of producing dual-purpose varieties of key crops for mixed crop-livestock systems given that these systems will be crucial in feeding the next 3 billion people.

Investments needed to help poor people take advantage of an on-going boom in livestock production in developing countries

Ploughing with cattle in West Bengal

Following the 2008/9 global food price crisis, agricultural experts agree that more investment in food production is needed to meet increasing world food demand. Global food security, however, is unlikely to be achieved unless livestock production is made more efficient.

Farm animals fulfil an important role in developing communities, where many people depend on mixed crop-and-livestock farming systems or live in marginal areas where animal agriculture is the only means of producing food. For most of the world’s poorest, about 600 million people, animals provide not only milk, meat and eggs but are also a source of draught power and manure for crop farming, resources that help livestock keepers diversify their income.

For many of these livestock keepers, greater investment in livestock production would make a significant difference in helping them come out of poverty by increasing their sources of food and income. 

The role of livestock in developing communities: Enhancing multifunctionality, a new book co-published by the University of the Free State South Africa, the Technical Centre for Agricultural and Rural Cooperation (CTA) and the International Livestock Research Institute (ILRI), argues that a better understanding of the multiple roles played by livestock in developing communities will help decision-makers and development practitioners not only improve the livestock sector’s efficiency and productivity but, through that, accelerate economic development in poor countries.

Livestock production in the developing world faces the challenge of how to meet an increasing demand for meat, milk and eggs with limited land, water and other natural resources, say two of the book’s authors, Siboniso Moyo, ILRI’s representative in southern Africa, and Frans Swanepoel, senior director of research and professor of sustainable agriculture at the University of the Free State, in Bloemfontein, South Africa.

Examining trends and drivers in livestock production in developing communities, the authors say that the smallholder livestock sector needs to adapt to increasing population and urbanization and the other changes coming in the wake of these changes, such as rapidly changing livestock systems, environments, climates and consumption patterns. All these changes, they say, require stronger policies and institutions.

The authors propose strengthening institutions and policies, providing livestock owners with credit, improving veterinary services, increasing the delivery and uptake of livestock technologies and improving the infrastructure of livestock markets.

The increasing demand for livestock in developing countries due to rising populations and incomes offers many poor livestock keepers new opportunities to raise their incomes by increasing the production and marketing of their livestock products. The main questions are how to include poor people in this livestock boom, and how to help smallholders increase their livestock production while making more efficient use of their land, water and native stock.

Three other big challenges of the fast-changing livestock sector in poor countries are finding ways to feed the increasing numbers of animals in the face of diminishing natural resources, developing diagnostics and vaccines to better protect animals against neglected tropical diseases of livestock as well as zoonotic diseases, which are shared by livestock and people, and finding optimal ways for small-scale livestock keepers to adapt to climate change and reduce their production of greenhouse gases.

The authors, however, note that rising prices of livestock products can open up new market opportunities for small-scale producers, though this alone will not guarantee their competitiveness. Without support, many smallholder livestock producers, especially those in marginal areas, with limited access to information and knowledge, will find it difficult to compete with larger livestock operations in meeting the increasing demand for livestock products while also meeting the more stringent food quality and safety standards the new market is demanding.

‘The livestock sector is an important part of developing communities and the multiple roles that livestock play in meeting the livelihoods of people need to be enhanced for the sector to continue contributing to poverty reduction,’ the book says. ‘Research and development agencies need to come together to address these challenges comprehensively.’

This book provides a list of ‘Livestock development projects that make a difference’ and ways to promote gender equality and empower women through livestock development. Watch for more highlights from the book in upcoming ILRI news articles.

The role livestock play in women's livelihoods in Africa and Asia: New review

Posted on by

A new discussion paper on Livestock and Women’s Livelihoods: A Review of the Recent Evidence has just been published by a group at the International Livestock Research Institute (ILRI) led by agricultural economist Patti Kristjanson.

This paper synthesizes evidence of the contributions that livestock make to the livelihoods of poor women in sub-Saharan Africa and South Asia and identifies factors that enhance or constrain livestock-related opportunities for women. The scientists apply a gender lens to three livestock-related pathways out of poverty—securing livestock assets; increasing livestock productivity; and enhancing participation in livestock markets. For each pathway, the authors summarize what is known and what this knowledge implies for programmatic and policy interventions.

Assembling this information, say the authors, 'is a first step towards identifying some of the large gaps in our evidence base as well as some indications of the kinds of research and development interventions, made in relation to which species and value chains, that appear most likely to benefit poor women and their families.'

The following is the introduction to this paper.

'After several years of relative neglect, livestock in livelihood studies are in the limelight, as the realization dawns—once again—that livestock are important for livelihoods and have significant potential for poverty alleviation, often in areas where few other options exist of the 2010. However, there is also an increasing awareness that certain types of livestock systems are associated with important downsides such as environmental degradation, greenhouse gas emissions, zoonotic and emerging infectious diseases, or food-borne illnesses. There is a need to balance these positive and negative aspects as is made clear by the title of the recent State of Food and Agriculture (SOFA) report ‘Livestock in the balance’ (FAO 2009). Gender will be central to achieving this balance.

'Livestock are important in women’s livelihoods and asset portfolios. The fact that past livestock interventions appeared to not benefit women led to the inception of considerable research on gender and livestock systems in the 1980s and 1990s. As a result, subsequent livestock development projects became better targeted, focusing on species (poultry, small ruminants, dairy cows) and using approaches (participatory, group-based) that make them, at least in theory, more appropriate for and accessible to women. 

'This is now an appropriate time to review past and current research on gender and livestock in order to identify pertinent issues and knowledge gaps for the livestock R4D agenda in coming decades.

'Although two-thirds of the world’s 600 million poor livestock keepers are rural women . . ., little research has been conducted in recent years on rural women’s roles in livestock keeping and the opportunities livestock-related interventions could offer them. This is in contrast to considerable research on the roles of women in small-scale crop farming, where their importance is widely recognized and lessons are emerging about how best to reach and support women through interventions and policies . . . . In the past decade, some researchers provided some evidence on causal relations between gender and livestock production . . . but, as this review demonstrates, there remains a dearth of quantitative information on this subject, especially for the mixed crop-livestock systems where most livestock and livestock keepers are found and where the major increases in production will have to occur if the global demand for meat, milk and other animal products in coming decades is to be met . . . . Furthermore, the multiple roles livestock play in livelihoods of the poor make generalizing about women’s roles in, and economic contributions to, livestock development problematic, and prioritizing livestock research and interventions for women’s development both challenging and necessary . . . . By applying a conceptual framework that allows us to organize and better understand existing knowledge about this complex subject, we aim to help identify research for development gaps and opportunities, made in relation to which species and value chains, that appear most likely to benefit poor women and their families.'

New book on livestock in developing countries

Siboniso Moyo, ILRI’s representative for southern Africa, holds a copy of ‘The role of livestock in developing communities: Enhancing multifunctionality’ which was recently launched in South Africa (photo credit: ILRI).

A new book co-published by the University of the Free State South Africa, the Technical Centre for Agricultural and Rural Cooperation (CTA) and the International Livestock Research Institute (ILRI) calls for more investment in livestock production to fight poverty and promote human health in developing countries.

The role of livestock in developing communities: Enhancing multifunctionality was launched on 9 November 2010 at the University of the Free State, in Bloemfontein, South Africa.

Farm animals continue to play several central roles in the livelihoods of the people in developing countries, ranging from providing households with high-quality foods, good nutrition and regular incomes to providing labourers with jobs, community members with social status and farmers and herders with ways to sustain food production.

This book highlights the livestock sector’s contribution to the social and economic progress of developing communities and advocates public- and private-sector investments in livestock production.

The publication is a product of a satellite symposium that was part of the 10th World Conference on Animal Production, held in Cape Town in November 2008. The symposium, jointly organized by ILRI and the University of the Free State, focused on livestock livelihood strategies for meeting the United Nations Millennium Development Goals.

‘We were pleased with the chance to work together with the University of the Free State in a side event during the World Conference of Animal Production 2008, which led to the production of this book,’ said Siboniso Moyo, ILRI’s representative for southern Africa, during the launch.

Moyo, along with Frans Swanepoel, senior director of research and professor of sustainable agriculture at the University of the Free State, Bloemfontein, South Africa, and Aldo Stroebel, director of international affairs and associate professor at the Center for Sustainable Agriculture and Rural Development at the same university, provided editorial oversight for the book.

John McDermott, ILRI’s deputy director general for research; Canagasaby Devendra, a tropical animal production specialist who formerly worked at ILRI, and Akke van der Zijpp, another former ILRI staff member who is now professor in livestock production systems at the Wageningen University and Research Centre, in the Netherlands, served in the editorial advisory committee that steered production of the book.

‘The “multifunctionality” of livestock is an important concept to understand when working with developing communities,’ said Moyo. ‘Viewing research and development challenges through a livestock lens,’ she said, ‘can help us make even greater use of the many functions livestock serve in poor communities and so as to increase their contribution to livelihoods.’

The book launch was attended by Monty Jones, executive director of the Forum for Agricultural Research in Africa, chairperson of the Global Forum of Agricultural Research and a World Food Prize Laureate (2004), who contributed the foreword to the book, and Norman Casey, president of the 10thWorld Conference of Animal Production 2008.

The book describes successful livestock development strategies, including ways to promote gender equality and to empower women through livestock development and ways to develop small-scale livestock enterprises without harming the environment.

Targeting academic professionals, industry experts, government officials and academics interested in increasing the contributions livestock enterprises can make to human well-being and developing-country economies, the new publication includes case studies and frameworks, discussions of key global policy development issues, and the main challenges and constraints of smallholder livestock production systems around the world.

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

Crop farmer in Western Kenya

Consolata James, a farmer in Western Kenya fighting striga, a ‘witches’ weed infesting her maize crop, will likely face shorter growing days and the arrival of new diseases with rising temperatures due to climate change (photo credit: CGIAR).

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

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

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

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

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

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

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

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

After successful eradication of rinderpest, African researchers now focus on peste des petits ruminants, the most urgent threat to African livestock

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Testing a tsetse-repellent technology

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

As agricultural leaders across the globe look for ways to increase investments in agriculture to boost world food production, experts in African livestock farming are meeting in Addis Ababa this week to deliberate on ways to get commercialized farm production, access to markets, innovations, gender issues and pro-poor policies right for Africa’s millions of small-scale livestock farmers and herders.

More than 70 percent of Africa’s rural poor are livestock farmers. Each farm animal raised is a rare source of high-quality food, particularly of dietary protein, minerals, vitamins and micronutrients, for these households. Pastoralists, who rely on herding their animal stock to survive in the continent’s dry and otherwise marginalized environments, also make up a significant number of Africa’s population.

‘There is a growing recognition by governments and donors that expanding investment in the agricultural sector is a cornerstone for alleviating poverty and building assets in Africa and other developing regions,’ said Carlos Seré, director general of the International Livestock Research Institute (ILRI).

‘Smart investments targeting the developing world's growing numbers of livestock keepers (who make up about 1 billion people today) is a win-win-win,’ said Seré. ‘Such investments promise not only to greatly increase global food security but also to generate profits for both poor livestock producers and agribusinesses.’

Livestock production today employs more than 1.3 billion people globally. Most African small-scale farmers practice mixed farming systems that combine both crop farming and livestock keeping. Globally, these mixed systems produce the majority of the world’s food staples, including 89 percent of the maize, 91 percent of the rice, nearly 75 percent of the milk and 68 percent of the beef consumed.

Livestock-based enterprises are pathways out of poverty for many people in Africa, for whom animals are a source of nourishing foods and regular incomes. With demand for milk, meat and eggs rising fast in many developing countries, the raising and marketing of animals and animal products also allows many people to take advantage of the new growth opportunities in this sector.

Despite the vibrancy of the livestock sector in Africa, much of the investments in African agriculture for food security to date has focused almost exclusively on crop farming. That is a mistake, says Seré, as are many investments made to boost crop and livestock production systems independently.

A livestock scourge eradicated
This is an opportune time for a meeting of Africa’s leading livestock experts. On 16 October 2010, to mark the United Nations World Food Day, the Food and Agriculture Organization of the United Nations and other world bodies chose to celebrate the eradication of rinderpest from the face of the earth. Probably the most remarkable achievement in the history of veterinary science, this milestone is expected to be announced in mid-2011, pending a review of final official disease status reports from a handful of countries to the World Organisation for Animal Health.

Rinderpest is a viral livestock disease that has afflicted Europe, Asia and Africa for centuries. It killed more than 90 percent of the domesticated animals, as well as untold numbers of people and plains game, in Africa at the turn of the 19th century, a devastation so complete that its impacts are still felt today, more than a century later. The last-known outbreak of rinderpest occurred in Kenya in 2001.

The key technical breakthrough in this effort involved development of an improved vaccine against rinderpest that did not require refrigeration up to the point of use. This allowed vets and technicians to backpack the vaccine into remote war-torn areas where the disease was a major problem. The AU-IBAR led the Pan-African Rinderpest Campaign, which coordinated the efforts that resulted in the eventual eradication of rinderpest from Africa.

Livestock conference to address main constraints to livestock production in Africa
It is against this background that leading scientists in African agriculture are gathering 25–28 October 2010 at the United Nation Conference Centre in Addis Ababa, Ethiopia, to discuss the challenges and opportunities of commercializing livestock agriculture in Africa at the Fifth All African Society of Animal Production.

Among specific areas to be addressed are livestock trade and markets, pastoralism and natural resource management, animal genetics and commercialization, climate change and its effects on livestock systems, livestock feeds, and the delivery of livestock services to smallholders and herders.

Despite its wealth of livestock resources, Africa produces livestock at relatively low levels, due to a range of technical, socioeconomic and biological challenges faced by smallholders and herders on the continent. These include weak policies and veterinary and other institutions; widespread parasitic, tropical and other livestock and zoonotic diseases; poor-quality feeds; inadequate inputs for livestock production; insufficient access to livestock markets and market information; and low market prices.

‘This conference is addressing policy and strategy gaps that have prevented African livestock producers from making the most of their livestock resources,’ said Tadelle Dessie, a scientist with ILRI. ‘Addressing these gaps should help raise the level of investment in livestock production and improve market access for small-scale livestock producers.’

Fix gender-based problems in livestock livelihoods
One potent way to enable Africa’s farmers and herders to benefit more from livestock production, say many who have researched the topic, is to redress gender imbalances in access to resources for livestock production. ‘Institutional, social and economic gender-based constraints inhibit women’s full participation in livestock markets and marketing,’ says Jemimah Njuki, a scientist with ILRI.

Research shows that many African women already have access to very local markets and that they already participate in different stages of livestock value chains. ‘Helping women access market-related information will help them help raise the continent’s livestock production levels,’ Njuki said, adding, ‘and should allow them to benefit more from their livestock enterprises.’

A Farm Animal Genetic Resources Project conducted by the International Livestock Research Institute (ILRI) and other partners to conserve indigenous livestock breeds in Bangladesh, Pakistan, Sri Lanka and Vietnam has been recognized by the United Nations Environment Programme (UNEP) as one of eleven global projects ‘assisting farmers in developing diversified and resilient agricultural systems to ensure communities and consumers have more predictable supplies of nutritious food.’

The ILRI project is featured in an UNEP booklet launched on Tuesday 19 October 2010 during the tenth meeting of the Conference of the Parties to the Convention on Biological Diversity, taking place in Nagoya, Japan.

Securing sustainability through conservation and use of agricultural biodiversity: The UNEP-GEF contribution provides lessons from projects about useful tools for conserving and managing agricultural biodiversity over the long term. The report features project partnerships among UNEP, the Global Environment Facility (GEF) and national and international organizations conducted over the last 10 years.

The ILRI-led and GEF-funded US$6.4-million Farm Animal Genetic Resources Project was started in 2009 to better conserve local breeds of chickens, goats and pigs that help sustain the livelihoods of poor farmers and the health and well-being of women and children in Asia.

As much as 10 per cent of the world’s livestock breeds have disappeared in the last six years, due mostly to substitution or cross-breeding of local indigenous animals with exotic commercial breeds. Most of the extant indigenous livestock breeds today are found in pastoral herds and on small farms in developing countries. Understudied and insufficiently documented, many of the strengths and potential benefits of these tropical local breeds remain untapped.

The Farm Animal Genetic Resource Project works to encourage wider use of local breeds, such as the Bengal goat in Bangladesh. Each of the four countries where the project is implemented has a long history of use of indigenous livestock and a rich diversity of animals, including the wild relatives of domestic livestock, which provide additional genetic resources for breeding programs to improve domestic animals.

ILRI’s project partners include the Bangladesh Agricultural University; the Pakistan Agricultural Research Council; the University of Peradeniya, in Sri Lanka; and the Vietnamese National Institute of Animal Husbandry, with more organizations expected to join the project later. By the time the project is completed, in 2014, these partners aim to have developed breeding tools for use in low-input livestock production systems, cost-benefit analysis tools for comparing breeding programs for different indigenous breeds and populations, and analytical frameworks for assessing policy and marketing options for farm animal genetic resources.

So far, with the input of local actors, including farmers, researchers and development agents, the Farm Animal Genetic Resources Project has developed baseline survey tools for assessing animal genetic biodiversity and constraints to its conservation. These tools will also be used to assess marketing opportunities for indigenous animals and the contributions these animals make to rural livelihoods. The project has also developed a flock and herd monitoring tool that helps to measure genetic and phenotypic diversity, to track genetic changes in livestock populations over time, and to capture the relations between indigenous domesticated animals and their wild relatives.

Mohamed Ibrahim, ILRI’s coordinator of this Asia project, says that the project is increasing the capacity of local institutions to collect and analyse data related to indigenous livestock breeds. ‘Our goal,’ says Ibrahim, ‘is to ensure that important chicken, goat and pig breeds in the four targeted Asian countries are protected for the future benefit of local farmers’.

Changes in Kenya’s dairy policy give wide-ranging benefits to milk industry players, new study shows

Recent findings from an assessment of the impacts of the Kenya dairy policy change of September 2004 show that changes in the sector, which incorporated small-scale milk producers and traders into the milk value chain and liberalised informal milk markets, have led to an increase in the amount of milk marketed, increased licensing of milk vendors and an increased demand for milk leading to benefits of US$230 million for Kenyan milk producers, vendors and consumers over the past 10 years (US$33 million per year).

The study, conducted between August 2007 and January 2008 among milk producers, vendors and dairy farmers in Nairobi, Nakuru, Thika and Kiambu towns, shows there was a threefold increase in marketed milk in all the towns with Nairobi recording a fourfold increase between 2004 and 2008. The findings also show that overall, ‘small-scale dairy operators have profited from quick, relatively high volume turnovers and welfare benefits to small-scale vendors have increased,’ since the introduction of the new policies in Kenya’s dairy industry.

According to the study ‘allowing licenced small-scale milk vendors to operate leads to increased milk supply to the retail market’ and it also found a continual increase in the number of small-scale milk vendors acquiring licences since 2004 to run milk bars to meet the increased demand for milk.

The study’s findings show that in Nairobi, the highest profits were gained by non-producer mobile traders, followed by milk bars and mobile transporters while in Nakuru those who benefited the most were producer mobile traders. The study, however, notes that the changes in policy also led to a decrease in market margins for retailers with an average 9% reduction across the surveyed towns. Milk traders in Nairobi experienced a reduction of Ksh 0.80 (US$0.012) per litre of milk sold.

With nearly 800,000 Kenyan smallholder households depending on dairying for their livelihoods and the dairy sector providing employment to over 350,000 people in milk collection, transportation, processing and sales; the dairy industry plays an important role in meeting the livelihood needs of poor Kenyan households as well as in contributing to Kenya’s economic development.

The study ‘Kenyan dairy policy change: influence pathways and economic impacts,’ was carried out by Amos Omore, a scientist with the International Livestock Research Institute (ILRI), among others researchers from Qatar University, Norwegian Institute of International Affairs and the World Agroforestry Centre (ICRAF). It assessed the impact of the Smallholder Dairy Project (SDP) and its contribution to the revised Kenya dairy policy and looked at the behavioural changes among field regulators and small-scale milk vendors resulting from recognition of their role in the milk value chain. The study also estimated the economic impact of the policy on producers, vendor and consumers.

Among the study’s other findings is that as a result of the new policies, milk handlers across the country are better trained, ‘with 85% reporting they had been trained on milk handling and quality control methods’ and that it is now much easier for producers and vendors to acquire licenses for their operations. Training and licensing is carried out by the Kenya Dairy Board and the Public Health Department who are now ensuring that licensed outlets and premises, especially those run by small-scale milk vendors, meet all hygiene, testing, sanitation and health requirements for milk handling. They also assist the milk vendors to meet these condition and this change in approach means that nearly all producers and traders understand the requirements of milk handling and quality control.

Kenya has made significant progress in liberalizing its dairy industry and is working towards training and licensing more small-scale milk vendors to allow them to fully engage in the formal milk sector. As a result of these experiences, the study says, there has been ‘behavioural changes among regulators and small-scale milk vendors that has led to positive economic benefits across Kenya.’

Assessing animal diseases: New paper urges use of value chain analysis and information economics to understand animal disease impacts

A new study by researchers working with the International Livestock Research Institute (ILRI) is recommending use of ‘bottom-up’ approaches that use the strengths offered by value chain analysis and information economics in assessing the impacts of animal diseases and their interaction with socio-economic and institutional factors in developing countries.

Authors Karl Rich, from the Norwegian Institute of International Affairs (NUPI) and on joint appointment with ILRI and Brian Perry, an honorary professor of veterinary medicine at the Universities of Edinburgh and Pretoria and formerly a leader of ILRI’s research team on animal health and food safety for trade, say economists and epidemiologists need to work more closely in assessing the impact of animal diseases. They recommend use of ‘participatory disease surveillance’ approaches that feature models of disease assessment that consider the context in which animal diseases occur and how they affect markets, livelihoods and poverty reduction especially in developing countries where livestock serve diverse commercial and cultural roles which affect disease control efforts.

In a paper ‘The economic and poverty impacts of animal diseases in developing countries: New roles, new demands for economics and epidemiology’ published in the 15 September 2010, online edition of the Preventative Veterinary Medicine journal, the scientists say both value chain analysis and information economics hold particular promise and relevance towards animal disease impact assessment.

They note that ‘normative’ approaches that try to guide how agents affected by diseases should behave (for example by emphasizing elimination of disease while relegating issues of disease mitigation, equity, gender and poverty) have had limited success in reducing poverty and disease prevalence in developing countries. The scientists suggest that new models that consider the context decision makers, farmers and value chain actors face in the event of animal disease outbreaks and what they actually do (not only what they should do) will contribute to more effective pro-poor policymaking.

The paper also recommends harmonizing divergent incentives among different stakeholders in developing countries noting that, for example, integrating the views of political economy and institutions engaged in animal health research will help to focus more broadly and systematically on incentives and the behaviour of those institutions and political actors, thereby helping researchers to better understand the economic impact of diseases.

The paper reviews the livelihoods and poverty impacts of animal diseases in the developing world, with a focus on Rift Valley fever, highly pathogenic avian influenza (HPAI) and foot and mouth disease. The paper also analyses the effects of these diseases through a poverty and value chains perspective and highlights ways that lessons from these perspectives can be aligned with disease control initiatives.

Rift Valley fever outbreaks are common in eastern Africa, especially after heavy rains, which lead to rises in numbers of mosquitoes that spread this viral zoonotic disease. Rift Valley fever affects cattle, sheep, goats and camels but also infects and kills humans. A recent outbreak of the disease between 2006 and 2007 killed more than 100 people in Kenya and led to significant loss of animals and livelihoods, especially for pastoralist livestock keepers.

Rich and Perry say the response of different stakeholders to diseases is based on their unique circumstances and constraints and their incentive for compliance also depends on such contexts. Their paper stresses the importance of ‘improved integration between epidemiology of disease and its relationships with economic behaviour.’

The authors call for a holistic look at the livestock sector as a system of interacting actors, each with their own values and constraints. They say that frameworks such as those offered by value chains can help identify the impacts that animal diseases generate. The  value chain framework’s emphasis on relationships, characteristics and dynamics among actors, can help identify not only who is impacted by animal disease but also how and why they are affected and how  different actors might behave and adjust in response to disease outbreaks.
