The International Livestock Research Institute (ILRI), a member of the CGIAR Consortium, is a non-profit organization based in Africa. ILRI’s mission is to use the best and safest livestock science available to confront poverty, hunger, and disease in the developing world, where livestock provide livelihoods and food for hundreds of millions of people.

One of ILRI’s most important priorities today is to help poor livestock keepers in Africa deal with the constant threat of a devastating disease called trypanosomiasis. This disease is arguably Africa’s most important livestock disease, wasting and killing cattle, commonly the most important asset of poor households. The human form of the disease is called sleeping sickness, which afflicts tens of thousands of people every year, killing many of them, and putting tens of millions more people at risk.

As part of ILRI’s comprehensive fight against trypanosomiasis, the institute is now in the very early stages of a project to develop disease-resistant cattle, which could save the lives of livestock and people both. Thus far, ILRI and its partners have taken a preliminary step in the process, which involved successfully cloning a male calf from one of East Africa’s most important cattle breeds, the Boran. The calf is healthy and is being raised at ILRI’s research facilities in Kenya.

A next step is to develop a new Boran clone modified with a gene that naturally confers resistance to the disease. This involves using a synthetic copy of a gene sequence originally identified in baboons that should protect cattle against this devastating disease.

A final step will be to use these disease-resistant cattle in breeding schemes that will provide African countries with another option in their fight against trypanosomiasis.

This research potentially offers a reliable, self-sustaining and cost-effective way of protecting tens of millions of African cattle against disease and untimely death, as well as dramatically reducing poverty across Africa. By reducing the reservoir of pathogens, this should also help to save thousands of human lives each year.

It could take up to two decades to develop disease-resistant cattle herds for Africa. ILRI and its partners are also continuing to pursue other options for fighting trypanosomiasis, such as rationale drug treatment and integrated disease control methods.

For ILRI, public safety and animal welfare are paramount; this means working with all the relevant Kenyan and international regulatory authorities to ensure that the highest bio-safety standards are always employed. In line with its commitment to transparency, ILRI places all of its research results in the public domain.

ILRI is working with a team that includes scientists from New York University, along with experts from the Roslin Institute in Scotland, and Michigan State University in the USA. The fundamental research aspects of this project are being funded by the US National Science Foundation.

Alliance meeting this week to battle global ‘goat plague’

Northern Kenya August 2008

The PPR virus, commonly known as goat plague, swept across southern Ethiopia and northern Kenya in 2008; Mohammed Noor lost 20 goats in the just one week and wondered how he would provide for his family (photo on Flickr by EC/ECHO/Daniel Dickinson).

Assembling for two days this week (29–30 Apr 2013) in Nairobi, Kenya, are members of a global alliance against ‘peste des petits ruminants’, abbreviated as ‘PPR’ and also known as ‘goat plague’ and ‘ovine rinderpest’.

Co-hosting this second meeting of the Global Peste de Petits Ruminants (PPR) Research Alliance (hereafter referred to as GPRA) are the International Livestock Research Institute (ILRI), which is headquartered in Nairobi; the Biosciences eastern and central Africa-iLRI hub (BecA-ILRI Hub), hosted and managed by ILRI; the African Union-Interafrican Bureau for Animal Resources (AU-IBAR), also based in Nairobi; and the Australian Agency for International Development (AusAID).

Among the 70 or so people attending are representatives from the Bill & Melinda Gates Foundation (BMGFYi Cao), the Global Alliance for Livestock Veterinary Medicines (GALVMedBapti Dungu), the International Atomic Energy Agency (IAEAAdama Diallo), the Pan African Veterinary Vaccine Centre (PANVAC), the Royal Veterinary College of the University of London Vet School (RVC), the United Nations Food and Agriculture Organization (FAOVincent Martin and Robert Allport, among others), the World Organisation for Animal Health (OIEJemi Domenech and Walter Masiga) and a range of national research institutions from developing countries where the disease is endemic.

What’s this alliance all about?
The GPRA is a participant-owned network of researchers and development professionals with an interest in the progressive control of PPR. The GPRA was inaugurated in 2012 at a meeting in London. GPRA aims to provide scientific and technical knowledge towards methods for the detection, control and eradication of PPR that are economically viable, socially practical and environmentally friendly.

Why, and how much, does PPR matter?
Infectious diseases remain the major limitation to livestock production globally and are a particular scourge in the developing world, where most of the world’s livestock are raised. Diseases not only kill farm animals but also cause production losses and hinder access to potentially high-value international livestock markets.

PPR, an infectious viral disease of sheep and goats, poses a major threat to the livelihoods of smallholder farmers in Africa as well as the Middle East and India. The disease is highly contagious, and has roughly an 80 per cent mortality rate in acute cases.

The impacts of PPR, which is closely related to rinderpest in cattle, have been expanding in recent years. At least 15 million sheep and goats are at risk of death from the disease in Kenya alone and the estimated economic impact of current PPR outbreaks—including production losses and disease control costs for Africa—is more than US$147 million per year. A recent outbreak of PPR in the Marakwet and Baringo districts of Kenya destroyed more than 2000 herds, with the disease spreading in days and farmers losing some KShs6 million (about US$70,000)  to the disease over about three months.

PPR is probably the most important killer of small ruminant populations in affected areas and some 65 per cent of the global small ruminant population is at risk from PPR.

Increasing interest in tackling PPR
Over the last several years, international experts and national authorities have both been increasingly prioritizing the progressive control of PPR, with the first phase designed to contribute to the long-term goal of eradication. Donor interest in this research and development area quickly ramped up over the past year. A current AusAID-funded project being conducted under a partnership between the BecA-ILRI Hub and Australia’s Commonwealth Scientific, Industrial and Research Organisation (CSIRO) has supported development of a thermostable vaccine now being piloted in vaccination campaigns in Sudan and Uganda, with similar work proposed for Ethiopia.

Need for coordinated and progressive control of PPR
There is a growing recognition of the need for, and potential benefits of, a coordinated approach to the progressive control of PPR. The disease is now one of the high priorities of AU-IBAR, FAO and OIE, all of which have strong networks and expertise to offer the alliance. The role of the Global PPR Research Alliance as a network of research and development organizations is to develop a coordinated strategy to contribute to the progressive control of PPR.

The Australian Government, together with AU-IBAR and ILRI, is supporting the second meeting of the GPRA to advance with many other stakeholders progressive global control of PPR, particularly through collaborative research. The GPRA supports the sharing of relevant information and results, the establishment of productive working relationships among stakeholders, the establishment of research and development projects of interest to some or all members, and the closer linking of strategic plans of all stakeholders in better control of this disease.

Is progressive eradication of PPR possible?
Wide calls for PPR’s progressive global eradication cite the following factors supporting this goal:

  • The close relationship of PPR/’goat plague’ with the recently eradicated ‘cattle plague’ known as ‘rinderpest’ (rinderpest was only the second infectious disease, and the first veterinary disease, to be eradicated from the globe)
  • The availability of effective vaccines against PPR
  • The development of heat-stable PPR vaccines, following the same procedures that were so effective in developing a heat-stable rinderpest vaccine
  • The opportunity to increase focus on Africa and Asia’s small ruminants, which are of critical importance to the livelihoods of rural smallholder and pastoralist communities in many of the world’s poorest countries
  • The existence of vaccines and diagnostics considered sufficient to initiate the program; the current vaccines (based on the strain Nigeria 75/1) are safe, efficacious and provide life-long immunity.

More about the AusAID-funded PPR project at the BecA-ILRI Hub
The Australian Government via AusAID has funded development at ILRI of thermostable formulations of the PPR vaccine that provide a level of stability in the field as high as that demonstrated in the vaccine used to eradicate rinderpest. The project team has demonstrated that the PPR vaccine can be stored without refrigeration for extended periods of time without significant loss in viability. This is a crucial and significant success. Under the guidance of ILRI senior scientist Jeff Mariner and with the assistance of Australia’s CSIRO and BecA-ILRI Hub staff, the project team have developed strong links with AU-IBAR’s Henry Wamwayi, a senior member of his organization seconded to the PPR project.

Next steps
The project has built on lessons learned from the recent global eradication of rinderpest, which depended on two equally important breakthroughs for its success: development of an effective thermostable vaccine and effective vaccine delivery networks in remote as well as other regions. The next 12 months of the PPR research project will focus on testing the vaccine and delivery strategies in South Sudan and Uganda. Staff will assess in the field just how effective the vaccine is in controlling PPR infections. They’ll also investigate some practical incentives for encouraging livestock owners and livestock service delivery personnel to participation in PPR control programs. And they’ll look into ways to build and enhance public-private community partnerships to deliver the PPR vaccine.

The spatial ecology of pigs: Where free-range doesn’t come free

IMG_0080

A report on the economic as well as health risks of keeping free-range pigs in western Kenya has been published by scientists in the animal health laboratories at ILRI’s Nairobi, Kenya, campus; here, two of the authors, lead author Lian Thomas (left) and principal investigator Eric Fèvre (right), inspect a household pig in their project site, in Busia, in western Kenya (photo credit: ILRI/Charlie Pye-Smith).

Like your livestock products to come from free-range systems? Consider that a healthy alternative to the factory farming of livestock? Consider the lowly pig, and what serious pathogens it can pick up, and transmit to other animals and people, in the course of its daily outdoor scavenging for food. Consider also the scavenging pig’s coprophagic habits (consumption of faeces) and you may change your mind.

A recent study has brought those habits to light. The study was conducted in an area surrounding Busia town, in western Kenya (Busia lies near Kenya’s western border with Uganda; Lake Victoria lies to the south). The study was conducted by scientists at the International Livestock Research Institute (ILRI) and the University of Edinburgh to better understand the transmission of several pathogenic organisms. This is the first study to investigate the ecology of domestic pigs kept under a free-range system, utilizing GPS technology.

Most people in Busia farm for a living, raising livestock and growing maize and other staple food crops on small plots of land (the average farm size here is 0.5 ha). More than 66,000 pigs are estimated to be kept within a 45-km radius of Busia town.

A GPS collar was put on 10 pigs, each nearly 7 months old, that were recruited for this study. A handheld GPS unit was used to obtain the coordinates of the homesteads to which the selected pigs belonged; the perimeters of the homesteads and their main features, including human dwellings, cooking points, rubbish disposal areas and latrines, were all mapped. The pig collars recorded the coordinates of the pigs every 3 minutes during the course of one week.

All the 10 pigs were kept under free-range conditions, but also regularly fed supplementary crop and (mostly raw) household waste. All the pigs recruited were found to be infected with at least one parasite, with most in addition also having gastrointestinal parasites, and all carried ticks and head lice.

The pigs, which scavenge both day and night, were found to spend almost half their time outside the homestead, travelling an average of more than 4 km in a 12-hour period (both day and night), with a mean home range of 10,343 square meters. One implication of this is that a community approach to better controlling infectious diseases in pigs will be better suited to this farming area than an approach that targets individual household families.

Three of the ten pigs were found to be infected with Taenia solium, a pig tapeworm whose larva when ingested by humans in undercooked pork causes the human disease known as cysticercosis, which can cause seizures, epilepsy and other disorders, and can be fatal if not treated. T solium infection in pigs is acquired by their ingestion of infective eggs in human faecal material, which is commonly found in the pigs environments in rural parts of Africa as well as Mexico, South America and other developing regions.

This study found no correlation between the time a pig spent interacting with a latrine at its homestead and the T solium status of the pig. The paper’s authors conclude that ‘the presence or absence of a latrine in an individual homestead is of less relevance to parasite transmission than overall provision of sanitation for the wider community in which the pig roams’. With a quarter of the homesteads in the study area having no access to a latrine, forcing people to engage in open defecation, and with less than a third of the latrines properly enclosed, there are plenty of opportunties for scavenging pigs to find human faeces.

Improved husbandry practices, including the use of effective anthelmintics at correct dosages, would enhance pig health and production in this study area.

One of the interesting findings of the study is that all this pig roaming is likely to be helping to reduce the weight of the pigs at slaughter. Mean live weights at the abattoir in the Busia area are 30 kg, giving a dressed weight of only 22.5 kg and earning the farmer only KShs.2000–2500 (USD24–29) per animal.

Encouraging the confinement of pigs is likely to improve feed conversion and weight gain, by both reducing un-necessary energy expenditure as well as limiting parasite burden through environmental exposure.

‘Confinement of pigs would also reduce the risk of contact with other domestic or wild pigs: pig to pig contact is a driver of African swine fever (ASF) virus transmission. ASF regularly causes outbreaks in this region . . . . Confining pigs within correctly constructed pig stys would also reduce the chances of contact between pigs and tsetse flies.’ That matters because this western part of Kenya is a trypanosomiasis-endemic area and pigs are known to be important hosts and reservoirs of protozoan parasites that cause both human sleeping sickness, which eventually is fatal for all those who don’t get treatment, and African animal trypanosomiasis, a wasting disease of cattle and other livestock that is arguably Africa’s most devastating livestock disease.

In addition, both trichinellosis (caused by eating undercooked pork infected by the larva of a roundworm) and toxoplasmosis (caused by a protozoan pathogen through ingestion of cat faeces or undercooked meat) are ‘very real threats to these free-ranging pigs, with access to kitchen waste, in particular meat products, being a risk factor for infection. Such swill is also implicated in ASF transmission’.

While confining pigs would clearly be advantageous for all of these reasons, the practice of free range will likely be hard to displace, not least because this low-input system is within the scarce means of this region’s severely resource-poor farmers. Local extension services, therefore, will be wise to use carrots as well as sticks to persuade farmers to start ‘zero-scavenging’ pig husbandry, Fortunately, as this study indicates, they can do this by demonstrating to farmers the economic as well as health benefits they will accrue by penning, and pen-feeding, their free-ranging pigs.

Better grass for better smallholder dairying in East Africa

The tuft of grass minor, by Albrecht Durer (via Wikipaintings).

An impact case study on Getting superior Napier grass to dairy farmers in East Africa was published on 1 Mar 2013 by the European Initiative for Agricultural Research for Development (EIARD), the International Livestock Research Institute (ILRI) and the Kenya Agricultural Research institute (KARI). Excerpts follow.

To meet demand for high-yielding, disease resistant fodder from smallholder dairy farmers in East Africa, scientists from the Kenya Agricultural Research Institute (KARI) and the International Livestock Research Institute (ILRI) worked together to select and distribute smut-resistant varieties of Napier grass.

‘Napier grass has become the most important fodder crop in Kenya, but 20 years ago head smut disease began to have a devastating impact, turning valuable fodder into thin, shrivelled stems. With the cost of disease control using systemic fungicide beyond the means of most smallholder dairy farmers, KARI began work to select smut-resistant varieties.

‘With access to Napier grass germplasm from ILRI’s genebank, KARI developed two resistant varieties — Kakamega I and Kakamega II. Favourable laboratory results were confirmed in farmer’s fields and work began to multiply planting material. Within a year, cuttings were distributed to over 10,000 smallholder farmers. The new varieties are not quite as productive as the best of Kenya’s local Napier grass varieties, but have still proven popular in smut-affected areas. By 2007, 13 per cent of farmers were using Kakamega I for zero grazing systems in smut prone areas.

‘The chance of head smut resistance breaking down in the new varieties is high, so KARI is screening more materials from ILRI, which is continuing to build its Napier grass collection to have germplasm available to screen for new resistant varieties. In 2012, ILRI provided the Brazilian Agricultural Research Corporation, Embrapa, with Kakamega I and II to enable researchers to use them to develop higher yielding and more nutritious resistant varieties. . . .

Background
‘Dairy farming, Kenya’s leading livestock sector activity, is vital for the livelihoods and food security of millions of Kenyans. More than 80 per cent of milk produced and sold in Kenya comes from smallholder farmers, typically raising just one or two dairy cows on small plots of land. Women perform half of all dairy related activities in Kenya, which improves household welfare, primarily through increased household income and milk consumption.

‘With a growing population and shrinking areas for pasture, cattle are increasingly being fed on crop residues, cultivated fodder and some concentrates. Ninety per cent of farmers now produce on-farm feeds. Being able to provide enough good quality fodder is by far the most important factor in achieving high milk quality and yield, with a well fed animal producing two or three times more milk than an averagely fed one.

‘The high yielding fodder, Napier grass — Pennisetum purpureum — has become by far the most important due to its wide adaptation to different regions, high yield and ease of propagation and management. Napier grass constitutes between 40–80 per cent of the forage for more than 0.6 million smallholder dairy farms. With fodder in high demand, selling Napier grass as a business has good potential for improving smallholder livelihoods. According to a recent survey, up to 58 per cent of Kenyan smallholder farmers already sell fodder, including crop residues, straw or grass.

‘However, in the early 1990s, head smut disease, caused by the fungus Ustilago kamerunensis, began to have a devastating impact on Napier grass. Spread rapidly by wind and infected plant material, smut turned valuable Napier grass into thin, shrivelled stems and reduced yields by 25–46 per cent. For smallholder farmers, the threat was very serious.

‘Disease control using systemic fungicide in fodder crops is very expensive and therefore beyond the means of most smallholders. Using tolerant high yielding varieties is a cost effective solution and avoids the additional costs of moving to a different feeding system. ILRI maintains an international collection of forage germplasm under the auspices of the International Treaty on Plant Genetic Resources for Food and Agriculture. The state of the art genebank, based in Ethiopia, holds over 19,000 forage accessions, including 60 genotypes of Napier grass. . . .’

Funding
ILRI received direct funding from the European Union, Germany, Switzerland and the United Kingdom to support their forage diversity work and forage genebank in addition to funding from CGIAR.

The ‘cream’ from more efficient dairying: Kenya to pilot scheme to pay smallholders for their environmental services

Global Agenda: 1 of 3 objectives

One of three objectives of the Global Agenda of Action in Support of Sustainable Livestock Sector Development. Its Third Multi-Stakeholder Platform Meeting was co-hosted in Nairobi, Kenya, by ILRI, FAO and AU-IBAR, 22-24 Jan 2013 (photo credit: ILRI/Susan MacMillan).

Guest blog post by ILRI’s Simon Fraval

In collaboration with the Food and Agricultural Organization of the United Nations (FAO) and the Kenya Ministry of Livestock Development, researchers at the International Livestock Research Institute (ILRI) are assessing the feasibility of the Kenyan dairy industry obtaining payment for its environmental services through productivity gains. (See this ILRI position paper for more information on ‘payment for environmental services’ schemes).

Reducing the level of greenhouse gases generated per unit of milk produced by smallholder farmers could be attractive to environmental markets. While this project will not provide direct money transfers to Kenya’s dairy farmers, it will support agricultural extension for better cow nutrition and other interventions made to increase milk production while also reducing emissions of greenhouse gases per unit of milk.

The concept gained momentum at an interim preparatory committee meeting of the Global Agenda of Action in Support of Sustainable Livestock Sector Development held in Rome in September 2012.

The Global Agenda is committed to broad-based, voluntary and informal stakeholder actions improving the performance of the livestock sector. It ambitiously aims to protect natural resources as well as to reduce poverty and protect public health. The Agenda’s stakeholders have agreed initially to focus on the following three objectives: Close the efficiency gap in livestock production systems, restore value to grasslands’ environmental services and sustainable livelihoods, and recover and recycle nutrients and energy contained in animal manure. The Agenda is working to achieve these objectives largely through consulting and networking, analyzing and informing, and guiding and piloting.

Progress on the Kenya dairy pilot ‘payment for environmental services’ project was presented at the third multi-stakeholder platform meeting of the Global Agenda, held in Nairobi, Kenya, 22–24 January 2013. This project provided a practical example of the Agenda’s core activity in piloting novel approaches to ‘close the efficiency gap’. The presentation to the Global Agenda meeting can be found on its Livestock Dialogue website.

Following the progress update provided at the mid-January 2013 Global Agenda meeting, a stakeholder workshop was held later in the month (29 Jan 2013) engaging representatives from the Kenya Dairy Board, the Kenya Agricultural Research Institute, the Kenya Dairy Processors Association, Kenyan livestock and cooperation ministries, development organizations and ILRI. The workshop was attended by Julius Kiptarus, Director of Livestock Production in Kenya’s Ministry of Livestock Development.

Stakeholders of the pilot ‘payment for environmental services’ project for Kenya’s dairy industry discussed the intricacies of such schemes, particularly carbon markets; site selection; potential greenhouse gas mitigation activities; and the design of a feasibility study. View slide presentations from this workshop here.

This pilot project is the first to access markets for payment for environmental services schemes through productivity gains in smallholder livestock enterprises. With the setting of this precedent and development of an internationally recognized methodology, development organizations will be able to replicate this pilot project and draw funding from the carbon market and other providers of ‘payment for environmental services’ schemes.

Animal-to-human diseases: From panic to planning–new recommendations for policymakers

Greatest Burden of Zoonoses Falls on One Billion Poor Livestock Keepers

Map by ILRI, published in an ILRI report to the UK Department for International Development (DFID): Mapping of Poverty and Likely Zoonoses Hotspots, 2012.

The UK’s Institute for Development Studies (IDS) has published a 4-page Rapid Response Briefing titled ’Zoonoses: From panic to planning’.

Veterinary epidemiologist Delia Grace, who is based at the International Livestock Research Institute (ILRI), along with other members of a Dynamic Drivers of Disease in Africa Consortium, based at the STEPS Centre at IDS, c0-authored the document.

The briefing recommends that policymakers take a ‘One-Health’ approach to managing zoonotic diseases.

‘Over two thirds of all human infectious diseases have their origins in animals. The rate at which these zoonotic diseases have appeared in people has increased over the past 40 years, with at least 43 newly identified outbreaks since 2004. In 2012, outbreaks included Ebola in Uganda . . . , yellow fever in the Democratic Republic of Congo and Rift Valley fever (RVF) in Mauritania.

‘Zoonotic diseases have a huge impact – and a disproportionate one on the poorest people in the poorest countries. In low-income countries, 20% of human sickness and death is due to zoonoses. Poor people suffer further when development implications are not factored into disease planning and response strategies.

‘A new, integrated “One Health” approach to zoonoses that moves away from top-down disease-focused intervention is urgently needed. With this, we can put people first by factoring development implications into disease preparation and response strategies – and so move from panic to planning.

Read the Rapid Response Briefing: Zoonoses: From panic to planning, published Jan 2013 by the Dynamic Drivers of Disease in Africa Consortium and funded by the UK Department for International Development (DFID).

About the Dynamic Drivers of Disease in Africa
The Dynamic Drivers of Disease in Africa is a consortium of 30 researchers from 19 institutions in Africa, Europe and America. It conducts a major program to advance understanding of the connections between disease and environment in Africa. Its focus is animal-to-human disease transmission and its objective is to help move people out of poverty and promote social justice.

Over the past few decades, more than 60 per cent of emerging infectious diseases affecting humans have had their origin in wildlife or livestock. As well as presenting a threat of global disease outbreak, these zoonotic diseases are quietly devastating lives and livelihoods. At present, zoonoses are poorly understood and under-measured — and therefore under-prioritized in national and international health systems. There is great need for evidence and knowledge to inform effective, integrated One Health approaches to disease control. This Consortium is working to provide this evidence and knowledge.

Natural and social scientists in the Consortium are working to provide this evidence and knowledge for four zoonotic diseases, each affected in different ways by ecosystem changes and having different impacts on people’s health, wellbeing and livelihoods:

  • Henipavirus infection in Ghana
  • Rift Valley fever in Kenya
  • Lassa fever in Sierra Leone
  • Trypanosomiasis in Zambia and Zimbabwe

Of the 30 scientists working in the consortium, 4 are from ILRI: In addition to Delia Grace, these include Bernard Bett, a Kenyan veterinary epidemiologist with research interests in the transmission patterns of infectious diseases as well as the technical effectiveness of disease control measures; Steve Kemp, a British molecular geneticist particularly interested in the mechanisms of innate resistance to disease in livestock and mouse models, and Tom Randolph, an American agricultural economist whose research interests have included animal and human health issues and assessments of the impacts of disease control programs.

Delia Grace leads a program on Prevention and Control of Agriculture-associated Diseases, which is one of four components of a CGIAR Research Program on Agriculture for Nutrition and Health. Tom Randolph directs the CGIAR Research Program on Livestock and Fish. Steve Kemp is acting director of ILRI’s Biotechnology Theme.

 

 

Pastoral livestock development in the Horn: Where the centre cannot (should not) hold

Pastoralism and Development in Africa

Who eats better, pastoral children in mobile herding or settled communities? (answer: mobile). Which kind of tropical lands are among those most at risk of being grabbed by outsiders for development? (rangelands). Are pastoral women benefitting at all from recent changes in pastoral livelihoods? (yes). Which region in the world has the largest concentration of camel herds in the the world? (Horn of Africa). Where are camel export opportunities the greatest? (Kenya/Ethiopa borderlands). Is the growth of ‘town camels and milk villages’ in the Somali region of Ethiopia largely the result of one man’s (desperate) innovation? (yes). Which is the more productive dryland livestock system, ranching or pastoralism? (pastoralism). Is irrigation involving pastoralists new? (no). Are we missing opportunities to make irrigated agriculture a valuable alternative or additional livelihoods to pastoralism? (perhaps).

The answers to these and other fascinating questions most of us will never have thought to even ask are found in a new book, Pastoralism and Development in Africa: Dynamic Change at the Margins, edited by Andy Catley, of the Feinstein International Center, at Tufts University; Jeremy Lind, of the Institute of Development Studies at the University of Sussex and Future Agricultures Consortium; and Ian Scoones, of the Institute of Development Studies, the STEPS Centre and the Future Agricultures Consortium. Published in 2012, it includes a chapter by scientists at the International Livestock Research Institute (ILRI): Climate change in sub-Saharan Africa: What consequences for pastoralism?

Thirty-six experts in pastoral development update us on what’s so in pastoral development in the Greater Horn of Africa, highlighting innovation and entrepreneurialism, cooperation and networking and diverse approaches rarely in line with standard development prescriptions. The book highlights diverse pathways of development, going beyond the standard ‘aid’ and ‘disaster’ narratives. The book’s editors argue that ‘by making the margins the centre of our thinking, a different view of future pathways emerges’. Contributions to the book were originally presented at an international conference on The Future of Pastoralism in Africa, held at ILRI’s campus in Addis Ababa, Ethiopia, in Mar 2011.

Here are a few of the book’s ‘unstandard’ ways of looking at pastoralism.

‘Overall, mainstream pastoral development is a litany of failure. . . . Pastoral borderlands are . . . beyond the reach of the state, and so the development industry.  ·  Perhaps no other livelihood system has suffered more from biased language and narratives than pastoralism. . . . Hidden in these narratives also are political agendas that perceive mobile pastoralism as a security and political threat to the state, and, therefore, in need of controlling or eliminating.  ·  To avoid the Malthusian label, or simply out of ignorance, many social scientists have neglected the important implications of demographic trends in pastoral areas. . . . Some of the fastest growing towns in Kenya are in pastoralist districts.  ·  Local demand for education is consistently high among pastoralists, a pattern that was not the case even 10–15 years ago.  ·   It seems feasible . . . to propose a pastoral livestock and meat trade value approaching US$1 billion for the Horn in 2010.  ·  The past dominant livestock practice characterized as traditional mobile pastoralism” is increasingly rare. . . . The creation of a relatively elite commercial class within pastoral societies is occurring at a rapid pace in some areas.  ·  . . . [P]astoral lands are vulnerable to being grabbed. On a scale never before envisioned, the most valued pastoral lands are being acquired through state allocation or purchase . . . . The Tana Delta sits at the precipice of an unprecedented transformation as a range of investors seek to acquire large tracts of land to produce food and biofuels and extract minerals, often at the expense of pastoralists’ access to key resources. . . . A notable facet of changing livelihoods in the Tana Delta is the increasingly important role of women in the diversifying economy, a trend seen elsewhere in the region. . . . Until now, pastoralists have been mostly unsuccessful at challenging proposed land deals through the Kenyan courts.  ·  The shift from a breeding herd to a trading herd is perhaps the biggest shift in Maasai pastoralism.  ·  Although drought is a perennial risk to pastoralist livelihoods, an emerging concern is securing access to high value fodder and other resources to support herds, in areas where rangelands are becoming increasingly fragmented due to capture of key resource sites.  ·  During the 2009–2011 drought in the Horn of Africa, several hundred pastoralists who participated in an Index-Based Livestock Insurance (IBLI) scheme in northern Kenya received cash payments.  ·  Despite its many challenges, mobile pastoralism will continue in low-rainfall rangelands throughout the Horn for the simple reason that a more viable, alternative land use system for these areas has not been found. . . . But the nature of pastoralism in 2030 will be very different than today in 2012. . . .’

One of the book’s chapters is on Climate change in sub-Saharan Africa: What consequences for pastoralism? It was written by ILRI’s Polly Ericksen (USA), whose broad expertise includes food systems, ecosystem services and adaptations to climate change by poor agricultural and pastoral societies; and her ILRI colleagues Jan de Leeuw (Netherlands), an ecologist specializing in rangelands (who has since moved to ILRI’s sister Nairobi CGIAR centre, the World Agroforestry Centre); Mohammed Said (Kenyan), an ecologist specializing in remote sensing and community mapping; Philip Thornton (UK) and Mario Herrero (Costa Rica), agricultural systems analysts who focus on the impacts of climate and other changes on the world’s poor countries and communities; and An Notenbaert (Belgium), a land use planner and spatial analyst.

The ILRI scientists argue that if we’re going to find ways to adapt to climate change, we’re going to need to learn from pastoralists — who, after all, are demonstrably supreme managers of highly variable climates in addition to rapidly changing social, economic and political contexts — about how to make sustainable and profitable, if cyclical and opportunistic, use of increasingly scarce, temporally erratic and spatially scattered water, land, forage and other natural resources.

In important respects, pastoral people are at the forefront of responses to climate change, given their experience managing high climate variability over the centuries. Insights from pastoral systems are critical for generating wider lessons for climate adaptation responses.’

What scientists don’t know about climate change in these and other drylands, they warn, is much, much greater than what we do know. So:

The key question is how to make choices today given uncertainties of the future.’

Because ‘the more arid a pastoral environment, the less predictable the rainfall’, and because ‘vegetation growth closely follows rainfall amount, frequency and duration, . . . the primary production of rangelands is variable in time and space’, with the primary driver of this variability in livestock production in pastoral areas being the availability or scarcity of forages for feeding herds of ruminant animals (e.g., cattle, sheep, goats, camels). In severe or prolonged droughts, forage and water scarcity become a lethal combination, killing animals en masse. The authors quote former ILRI scientist David Ndedianye, a Maasai from the Kitengela rangelands in Nairobi’s backyard, and other ILRI colleagues who report in a 2011 paper on pastoral mobility that pastoral livestock losses in a 2005 drought in the Horn were between 14 and 43% in southern Kenya and as high as 80% in a drought devastating the same region in 2009. It may take four or five years for a herd to recover after a major drought.

Evidence from a range of modelling efforts was used by the authors to calculate places in the global tropics where maximum temperatures are predicted to flip from less than 30 degrees C to greater than 30 degrees C by 2050. This temperature threshold is a limit for a number of staple crops, including maize beans and groundnut. Heat stress also affects grass and livestock productivity. Large areas in East African may undergo this flip, according to these models, although the authors warn that these predictions remain highly uncertain.

Thornton and Herrero in a background paper to the World Bank’s 2010 World Development Report investigated the impacts of increased drought frequency on livestock herd dynamics in Kenya’s Kajiado District. ‘Their results indicate that drought every five years keeps the herds stable as it allows sufficient time for the herds to re-establish. A once in three year drought interval by contrast drives livestock density to lower levels . . . . Hence, if there is a greater frequency of drought under climate change, this might have a lasting impact on stocking density, and the productivity of pastoral livestock systems.

The results were extrapolated to all arid and semi-arid districts in Kenya and estimated that 1.8 million animals could be lost by 2030 due to increased drought frequency, with a combined value of US$630 million due to losses in animals, milk and meat production. . . .’

In the face of changes in climate (historical and current), many pastoralists will change the species of animals they keep, or change the composition of the species in their herds. In the space of three decades (between 1997/8 and 2005–10) in Kenya, for example, the ratio of shoats (sheep and goats) to cattle kept increased significantly. Goats, as well as camels, are more drought tolerant than cattle, and also prefer browse to grasses.

Such changes in species mix and distribution will have important implications for overall livestock productivity and nutrition, as well as milk production.’

While change is and always has been fundamental to pastoralist livelihood strategies, much more—and much more rapid and diverse—change is now sweeping the Horn and many of the other drylands of the world, with local population explosions and increasing rangeland fragmentation and civil conflicts coming on top of climate and other global changes whose nature remains highly uncertain. New threats are appearing, as well as new opportunities.

While the ILRI team argues that we can and should look to pastoralist cultures, strategies and innovations for insights into how the wider world can adapt better to climate change, they also say that ‘development at the margins’ is going to be successful only where pastoralists, climate modellers and other scientists  work together:

. . . [A]daptation and response strategies in increasingly variable environments must emerge from grounded local experience and knowledge, as well as be informed by increasingly sophisticated [climate] modeling efforts.’

Cows in the cloud: Kenyans are registering their cows, and increasing their milk yields, on their mobile phones

Su Kahumbu

On Tue, 11 Dec 2012, Kenyan social entrepreneur Su Kahumbu gave ILRI’s fourth ‘livestock live talk’ seminar, titled ‘Livestock and mobile technology’, at the International Livestock Research Institute (ILRI), in Nairobi, Kenya.

Kahumbu founded Green Dreams Ltd and Green Dreams Tech Ltd companies, which are focused on creating solutions for small-scale organic farmers in Africa. She has 14 years experience across the whole of the organic value chains in Kenya, from production to consumption and policy to advocacy. Kahumbu is a TED Fellow and is spreading her passion through the TED network; her ambition is to help ‘Build a better Africa from the ground up’.

Kahumbu is also the creator of an Apps4Africa Award-winning app known as iCow, a mobile application officially launched in June 2011 that she developed to help small-scale dairy farmers track their cow’s fertility cycle. It prompts  farmers on vital days of cow gestation period, helps  farmers find the nearest vet and all service providers, collects and stores farmer milk and breeding records, and sends farmers best dairy practices.

A mother of three, Kahumbu started her presentation by confessing to her largely scientific audience that she knew little cows when she started and know little about technology . “What I feel I do know about is what smallholder farmers need to help them mitigate the big risks of farming. My presentation will take you through the development of iCow.

What keeps her up at night
‘There are a few things that keep me up at night. One billion people on the planet suffering from malnutrition. And climbing. Largely due to unsustainable agriculture and ecological practices. . . . We do produce enough food for the planet, but we only consume half of what we produce. Millions of tonnes are lost in post-harvest, transport, processing and retail.

‘That’s worrying. More worrying is that more than one in four Africans—218 million people—on this continent are suffering from undernourishment.

‘The current solutions I feel that we’ve been delivering to small-scale farmers and to farmers in general have been at the expense of our ecosystem and is resulting in dependence on very heavy, expensive inputs: fertilizers, adapted and modified seeds that generally the farmers cannot afford.

‘In working with farmers over the last few years, I’ve seen this continual vicious cycle, with farmers being pushed to adopt new technologies, and to spend more, and to get money from banks. And I don’t see this as sustainable, especially when the core problem is that we’re not focusing on the fertility of our soils.

‘On top of that, who is it that we call a farmer? Farmers in industrialized countries are mechanized, industiralized, subsidized, compared to farmers here who are, literally, unsupported, yet, in our case in Kenya, supply 80% of the national food. It’s quite shocking.

‘Farmers risks [here] are enormous. If I were to say to you, “Let’s all of us get out there and go get a job where we’re going to have weather on our doorsteps, poor storage, poor infrastructure, high inputs”, how many of us would actually say “That’s great, let’s go do it”? Yet we depend on these same smallholder farmers to feed us.

Going forward, one of the things I think we really need to focus on is what I’m largely doing with iCow, and that is focusing on reducing the risks of the smallholder farmer. . . .

It became quite evident that what farmers needed was knowledge, markets and finance. . . .

Mobiles in Kenya: A ‘huge, huge, huge opportunity’
‘We have today 80% mobile phone penetration across the country, with 100% penetration among 20 to 29 year olds. On the African continent, we have 700 million mobile phones using many mobile phone plans. That is a huge, huge, huge opportunity to get information out to farmers.

‘And that leads me to iCow. iCow is an agricultural information platform accessed primarily via mobile phones, although we do do some stuff on the web. You don’t have to have a smart phone. We started out using sms [short message service]. The objectives were to increase farmer productivity through increased knowledge.

The iCow ‘pipe’
‘I describe iCow as a pipe, with one end the farmers. . . . Farmers register their cow on the date the animal is served and we start to push sms’s to them along the gestation period of that animal, reminding the farmer when she’ll come into heat again. We continue to drip-feed information on best practices right up until the animal gives birth. If it’s a lactating animal, when tell them when and how to dry the cow off without it getting mastitis, etc.

‘To get a vet or AI, farmers simply send the word “vet” or “AI” plus the short code—the short code is 50-24—over one of the three largest networks in the country. When they send the word “vet”; they get a response asking them where they’re located, and they receive the telephone numbers and the names of the vets in their locality. Same with AI. This service is offered 24/7.  The system is automated so they can receive the information whenever they like. Both these features are quite popular.

‘As we took the product to market, we had to build in a customer care centre . . . . We found that many farmers knowing that there is a voice at the end of the system helps them adopt new technologies.

‘As we started to roll out the platform, on 3 June 2011, . . . we had to build another feature quite quickly, and that is what we call Mashauri. That is where farmers register to receive three sms messages a week, at this point in time across the value proposition of the cow. And so they get information on feeding, on vaccinations, on calf care, etc. But they don’t have to have registered their cow.

‘Soon after that, farmers started saying “I want to buy a cow”, “Where do I get  a heifer calf”. Or “I want to buy a dairy goat”. So we built a marketplace [called Soko]. Very, very easy. Just like Craig’sList [an online classified ad service in many cities and countries throughout the world], but on a mobile phone [rather than the internet]. Through a series of steps, a farmer posts what it is he wants to sell, and through a series a steps whoever is looking for that will simply get his telephone number. So if you’re selling a Toggenburg goat, you will put in “Toggenburg goat” and farmers looking for Toggenburg goats will get your number. . . .

‘As our database started to grow—today our database is 42,000 farmers—we put on a feature called Sauti. Again, farmers register for it, and if anything critical comes up, we can send them that information on their authority. . . .

‘And then Videos. An sms is only 160 characters long; you cannot put too much information in an sms. So we’ve put up 2-3-minute videos on our website and we’ve shown farmers who are registered what to do when they get to the nearest cybercafe; we send them short links where they’ll find short videos about  the information they’re looking for. . . .

TEDx Nairobi 2010: Su Kahumbu

Both ends of the iCow pipe are working
‘What we found was that as we were dealing with farmers, other people started getting interested—the other end of the pipe—the NGOs, government, practitioners on the ground, etc. We started getting requests from them to help reach farmers, in some cases just to do surveys, so that they could see very quickly how their programs were impacting on the ground. So both ends of the pipe are now actually working.

Virtual vets
‘We also found that sometimes farmers were requesting things from us that we couldn’t answer. And they weren’t very happy about the vets on the ground. So we thought, “What can we do about that?”. So we started looking at using vets in the virtual sense.

‘We formed a very simple system using Google Docs. We upload any question that we can’t deal with or that the farmer didn’t get an answer to on the ground to a few vets, and the vets send the messages among themselves and come up with the best answer that they send to us, that we then forward to the farmer.

‘It’s really interesting because we have vets in Uganda answering questions from farmers in Kenya. And we’ve had requests from Senegal, where they had only four vets on the ground, asking whether they can use the same system.

‘Long-term, it makes it very interesting how expertise and skills using the cloud can actually network and reach out across borders quite easily, if it is planned right and there is political support.

  • iCow is becoming an educational tool.
  • Profile of iCow farmer: 1–2 acres land, 2–3 cows, 20% women.
  • After 7 months, iCow farmers are getting 2–3 extra litres of milk per cow per day.
  • Other gains:

    Reduced veterinary costs
    Healthier animals

Amazing maize story
‘An interesting thing happened on April 10th, when the first information started coming out about maize disease in the country. Farmers were up in arms—they weren’t getting any responses from government. They wanted to know “What is the solution? What can we do?” Government was being quite, everybody was being quiet, because nobody knew what to do.

‘But we heard from some farmers on Facebook that one of the seed multiplication centres of KARI [the Kenya Agricultural Research Institute] had some good-quality disease-free seed. So we took that information, put it on our system and sent it to 11,000 farmers, using iCow. And literally, within minutes, the phone in that centre was ringing off the hook and farmers started to buy the seed using MPESA [Kenyan mobile phone financial service] and having it sent by matatu [Kenyan taxi]. Within three days, there was no seed left in that centre.

‘We called KARI and asked “What was the reaction?”. They said, “How did that happen? We now have to bulk up three times as much seed as we thought we needed. They expected to sell the seed over a six-month period and they sold it, literally, within days. So again, using technology to make those links, make those connections work. It was 6 weeks later that the seed problem hit the headlines in Kenya. I was so happy that at least we could do something that much earlier for farmers.

East Coast fever vaccine: 99% of Kenyan farmers want it
‘Many of you know, especially here in ILRI, that the ECF [East Coast fever] vaccination has just been launched  in Kitale. We worked with GALVmed to do a survey using iCow to find out what farmers felt about the vaccination. And 99% of those surveyed said they want the vaccination and said “When can we have it? Let us know straight away.”

‘We were invited to the launch and I’m happy to say that this is going to be a huge thing for the farmers in Africa. This is an awful disease killing up to 1.1. million livestock a year on the continent.

‘That brings me to the end of my presentation.

What iCow is doing, I believe, is turning our farmers, our survivors, our people on the land, whatever you want to call them, into knowledgable farmers. We currently have farmers in 42 different counties; we have 42,000 farmers in our database using different features of the platform.

Thank you.’

New vaccine launched today to protect Kenyan cattle against East Coast fever

Mrs Kivuti and Cow

Today is a red-letter day for livestock keepers in Kenya. A vaccine is being launched by the  Kenya Department of Veterinary Services that will help Kenyan farmers protect their dairy and other cattle against East Cost fever. The launch is being held in Kenya’s Kitale town.

For four decades, the Nairobi-based International Livestock Research Institute (ILRI) and its predecessor (the International Laboratory for Research on Animal Diseases, ILRAD) have conducted research on the lethal tick-borne cattle disease known as East Coast fever. ILRI’s work has focused on developing a new-generation ‘subunit’ vaccine, comprising molecular components of the causative parasite, while also developing molecular tools to enhance the quality of an infection-and-treatment (ITM) immunization method, consisting of whole live parasites.

The ITM vaccine was developed first by the former East African Veterinary Research Organisation, at Muguga, Kenya, between 1967 and 1977, now known as the Veterinary Research Centre, which is part of the Kenya Agricultural Research Institute (KARI) and which has continued to refine the vaccine.

ILRI produced the first commercial batch of the ITM vaccine in the late 1990s, at the request of the Food and Agriculture Organization of the United Nations. A decade later, on request from regional stakeholders, ILRI produced a second batch, which is now being used in East Africa. ILRI and KARI also supported Kenya’s Director of Veterinary Services (DVS) in his department’s successful trials that have confirmed the safety and effectiveness of the ITM vaccine, thus making way for the launch of its national distribution today.

Two ILRI scientists, Phil Toye and Henry Kiara, that have been involved in this research for many years are attending the launch. They say that East Coast fever continues to cause major economic and social losses to families in eastern, central and southern Africa.

Of the 46 million cattle in this region almost half are at risk from this disease, say Toye and Kiara.

‘ILRI’s work has focused on better understanding of the biology of the parasite that causes the disease and the host immune responses to infection. While the ITM vaccine was developed in the early 1970s at Muguga, Kenya, the vaccine was not readily taken up due to inadequate understanding of the biology and epidemiology of the diseases at the time.’

Scientists in KARI and ILRI continued to refine the technology to the point where it was deemed safe and effective to distribute the vaccine on a commercial basis to farmers. ILRI will continue working with Directors of Veterinary Services in the region to address any research questions that may arise as we continue to use this technology.

It gives me great pleasure today to congratulate the Kenya Department of Veterinary Services on this great occasion of the launch of the East Coast fever vaccine. ILRI is proud to have played a role in this and will continue to offer any research support needed to keep Kenya’s cattle safe from this deadly disease.—Phil Toye

 

More ‘crop per drop’? Only when ‘more milk per drop’ saves the poor as well as Nile Basin waterflows

Now it is time for the herders to cool their body

Ten years ago, scientists at the International Livestock Research Institute (ILRI) and the International Water Management Institute (IWMI) established a partnership centred at ILRI’s campus in Addis Ababa, Ethiopia. The partnership was formed to address widespread concerns that livestock consume excessive amounts of water and that livestock keeping is a major cause of water degradation. A statistic commonly reported, and believed, was that producing one kilogram of meat required 100,000 litres of water, mainly for production of livestock feed, in contrast to less than 3000 litres needed to grow most crops.

The ILRI-IWMI partners believed that these statements were neither sufficiently nuanced to note huge differences in the world’s livestock systems nor grounded in good science. But it was clear to them that if the figures were true, they needed to find ways to reduce livestock use of water resources and if the figures were not true, they needed to determine accurate estimates of water use. They were fortunate to be welcomed into the CGIAR Challenge Program on Water and Food (CPWF) and the CGIAR Comprehensive Assessment of Water and Agriculture, both of which enabled the new partners to pursue research on what was quickly termed ‘livestock water productivity’ in an African context.

Many unanswered questions remain, but the following consensus emerged from the ILRI-IWMI partnership.
1. African beef production typically uses one-tenth to one-fifth the amount of water used in industrialized countries and livestock systems; 11,000–18,000 litres of water are used to produce one kilogram of beef in Africa compared to the 100,000 litres for beef production that is so often reported (see above). It is clear that industrialized livestock production systems tend to use vastly more water per unit of beef produced than Africa’s livestock keepers, who typically integrate their raising of beef stock with food cropping on small plots of land, where the livestock enhance the cropping (e.g., via manure for fertilizing the soils and draught power for ploughing the land) and the cropping enhances the livestock (e.g., via the residues of grain crops used to feed the farm animals).

2. Because cattle and other livestock serve and benefit the world’s poor farmers in many ways, with meat being only one benefit that usually comes after an animal has served a long life on a farm, the water used in African smallholder livestock production systems generates many more benefits than meat alone.

3. Over the preceding half a century, much research had been conducted to increase crop water productivity, but virtually none to increase livestock water productivity. This dearth, along with the high and rising value of many animal products, suggests that returns on investments made to develop agricultural water resources for crops will be much greater if livestock are integrated in the cropping systems and factored into the water equations.

4. Finally, there still remains much room to increase livestock water productivity in Africa’s small-scale livestock production systems. Four strategies for doing this are outlined below and are included in a book that was launched earlier today in Addis Ababa.

But before we get to that press release, listen for a moment to Don Peden, a rangeland ecologist who led this research at ILRI for many years and who says the IWMI-ILRI partnership ‘was an extraordinary example of the potential for inter-centre collaboration.

I often think the partnership was as important as the research products it generated’, says Peden. ‘Many people and institutions helped make our collaborative work on water and livestock succeed. First on the list is Doug Merrey. Many of the CPWF staff made huge contributions and provided outstanding encouragement. There are too many to mention, but they include Jonathan Woolley, Alain Vidal, Seleshi Bekele, David Molden and Simon Cook.

‘We also owe a great debt to many of our partners’, Peden goes on to say. ‘This includes professors (the late) Gabriel Kiwuwa, David Mutetitka and Denis Mpairwe from Makerere University as well as Hamid Faki from Sudan’s Agricultural Research Corporation. And special mention should be made about Shirley Tarawali, now serving as ILRI’s director for Institutional Planning, who provided day-to-day encouragement and support throughout the project and made a tremendous contribution. And we also had a unique research team in ILRI’s People, Livestock and the Environment Theme that made successes possible.

In brief, the interpersonal interactions among all of these people and institutions and many others made this work possible. The success of the project lies in the people, and not just in the book.’

5 key messages regarding livestock and water—excerpted in full from the livestock chapter in the new—book follow.
(1) ‘Domestic animals contribute significantly to agricultural GDP throughout the Nile Basin and are major users of its water resources. However, investments in agricultural water development have largely ignored the livestock sector, resulting in negative or sub-optimal investment returns because the benefits of livestock were not considered and low-cost livestock-related interventions, such as provision of veterinary care, were not part of water project budgets and planning. Integrating livestock and crop development in the context of agricultural water development will often increase water productivity and avoid animal-induced land and water degradation. . . .

(2) ‘Under current management practices, livestock production and productivity cannot meet projected demands for animal products and services in the Nile Basin. Given the relative scarcity of water and the large amounts already used for agriculture, increased livestock water productivity is needed over large areas of the Basin. Significant opportunities exist to increase livestock water productivity through four basic strategies. These are:
‘a) utilizing feed sources that have inherently low water costs for their production
‘b) adoption of the state of the art animal science technology and policy options that increase animal and herd production efficiencies
‘c) adoption of water conservation options
‘d) optimally balancing the spatial distributions of animal feeds, drinking water supplies and livestock stocking rates across the basin and its landscapes. . . .

(3) ‘Suites of intervention options based on these strategies are likely to be more effective than a single-technology policy or management practice. Appropriate interventions must take account of spatially variable biophysical and socio-economic conditions. . . .

(4) ‘For millennia, pastoral livestock production has depended on mobility, enabling herders to cope with spatially and temporally variable rainfall and pasture. Recent expansion of rain-fed and irrigated croplands, along with political border and trade barriers has restricted mobility. Strategies are needed to ensure that existing and newly developed cropping practices allow for migration corridors along with water and feed availability. Where pastoralists have been displaced by irrigation or encroachment of agriculture into dry-season grazing and watering areas, feeds based on crop residues and by-products can offset loss of grazing land. . . .

(5) ‘In the Nile Basin, livestock currently utilize about 4 per cent of the total rainfall, and most of this takes place in rain-fed areas where water used is part of a depletion pathway that does not include the basin’s blue water resources. In these rain-fed areas, better vegetation and soil management can promote conversion of excessive evaporation to transpiration while restoring vegetative cover and increasing feed availability. Evidence suggests that livestock production can be increased significantly without placing additional demands on river water.’

Now (finally) on to that press release.

‘Tens of millions of small-scale farmers in 11 countries need improved stake in development of the Nile River Basin—News conference, Addis Ababa, 5 Nov 2012

ILRI livestock feed specialist Alan Duncan (right), joint Basin leader of the Nile Basin Development Challenge Programme, participated in a news conference today in Addis Ababa launching a new study on the Nile Basin and poverty reduction (photo credit: ILRI/Zerihun Sewunet).

As planetary emergencies go, finding ways to feed livestock more efficiently, with less water, typically do not find their way into ‘top ten’ lists. But today that topic was part of a discussion by a group of experts gathered in the Hilton Hotel in Addis Ababa, Ethiopia, to highlight the Nile River Basin’s potential to help 90 million people lift themselves and their families out of absolute poverty.

Despite attempts to cooperate, the 11 countries that share the Nile river, including a new nation, South Sudan, and the drought-ridden Horn of Africa, often disagree about how this precious and finite resource should be shared among the region’s some 180 million people—half of whom live below the poverty line—who rely on the river for their food and income.

But a new book by the CPWF argues that the risk of a ‘water war’ is secondary to ensuring that the poor have fair and easy access to the Nile. It incorporates new research to suggest that the river has enough water to supply dams and irrigate parched agriculture in all 11 countries—but that policymakers risk turning the poor into water ‘have nots’ if they don’t enact efficient and inclusive water management policies.

The authors of the book, The Nile River Basin: Water, Agriculture, Governance and Livelihoods, include leading hydrologists, economists, agriculturalists and social scientists. This book is the most comprehensive overview to date of an oft-discussed but persistently misunderstood river and region. To discuss the significance of the findings in the book were Seleshi Bekele Awulachew, a senior water resources and climate specialist at the United Nations Economic Commission for Africa; Simon Langan, head of the East Africa and Nile Basin office of IWMI; and Alan Duncan, a livestock scientist at ILRI.

Smallholder farmers need improved stake in Nile’s development
There is enough water in the Nile basin to support development, but small farmers are at risk of being marginalized, says the new book, which finds that the Nile River, together with its associated tributaries and rainfall, could provide 11 countries—including a new country, South Sudan, and the drought-plagued countries of the Horn of Africa—with enough water to support a vibrant agriculture sector, but that the poor in the region who rely on the river for their food and incomes risk missing out on these benefits without effective and inclusive water management policies.

The Nile River Basin: Water, Agriculture, Governance and Livelihoods, published by CPWF, incorporates new research and analysis to provide the most comprehensive analysis yet of the water, agriculture, governance and poverty challenges facing policymakers in the countries that rely on the water flowing through one of Africa’s most important basins. The book also argues that better cooperation among the riparian countries is required to share this precious resource.

This book will change the way people think about the world’s longest river’, said Vladimir Smakhtin, water availability and access theme leader at IWMI and one of the book’s co-authors.

Agriculture, the economic bedrock of all 11 Nile countries, and the most important source of income for the majority of the region’s people, is under increased pressure to feed the basin’s burgeoning population—already 180 million people, half of which live below the poverty line. According to the book, investing in a set of water management approaches known as ‘agricultural water management’, which include irrigation and rainwater collection, could help this water-scarce region grow enough food despite these dry growing conditions.

‘Improved agricultural water management, which the book shows is so key to the region’s economic growth, food security and poverty reduction, must be better integrated into the region’s agricultural policies, where it currently receives scant attention’, says Seleshi Bekele, senior water resources and climate specialist at the United Nations Economic Commission for Africa and one of the book’s co-authors. ‘It is tempting for these governments to focus on large-scale irrigation schemes, such as existing schemes in Sudan and Egypt, but more attention must also be paid to smaller, on-farm water management approaches that make use of rainwater and stored water resources such as aquifers.’

Lack of access to water is another area that could negatively impact the poor, according to the book. In the Nile Basin, poor people live further away from water sources than the wealthy, which forces them to travel longer distances to collect water. Women that are responsible for collecting water for their households and smallholder farmers who rely on rainwater to irrigate their crops would therefore benefit from policies that give them greater access to water in the Nile Basin.

We need to look beyond simply using water for crop production if we are to comprehensively address the issues of poverty in the region’, says David Molden, IMWI’s former director general and one of the book’s co-authors. ‘Water is a vital resource for many other activities, including small-scale enterprises like livestock and fisheries. This should not be forgotten in the rush to develop large-scale infrastructure.’

Improving governance, especially coordination among Nile Basin country governments, is another crucial aspect of ensuring that the poor benefit from the basin’s water resources. The book argues that the establishment of a permanent, international body—the Nile Basin Commission—to manage the river would play a key role in strengthening the region’s agriculture, socio-economic development and regional integration.

‘The Nile Basin is as long as it is complex—its poverty, productivity, vulnerability, water access and socio-economic conditions vary considerably’, says Molden. ‘Continued in-depth research and local analysis is essential to further understanding the issues and systems, and to design appropriate measures that all countries can sign on to.’

Interestingly, the book counters a common tendency to exaggerate reports of conflict among these countries over these complex management issues. ‘Past experience has shown that countries tend to cooperate when it comes to sharing water’, says Alain Vidal, CPWF’s director. ‘On the Nile, recent agreements between Egypt and Ethiopia show that even the most outspoken Basin country politicians are very aware that they have much more to gain through cooperation than confrontation.’

Notes

The CGIAR Challenge Program on Water and Food (CPWF) aims to increase the resilience of social and ecological systems through better water management for food production (crops, fisheries and livestock). The CPWF does this through an innovative research and development approach that brings together a broad range of scientists, development specialists, policymakers and communities to address the challenges of food security, poverty and water scarcity. The CPWF is currently working in six river basins globally: Andes, Ganges, Limpopo, Mekong, Nile and Volta www.waterandfood.org

The International Water Management Institute (IWMI) is a nonprofit, scientific research organization focusing on the sustainable use of land and water resources in agriculture to benefit poor people in developing countries. IWMI’s mission is “to improve the management of land and water resources for food, livelihoods and the environment.” IWMI has its headquarters in Colombo, Sri Lanka, and regional offices across Asia and Africa. The Institute works in partnership with developing countries, international and national research institutes, universities and other organizations to develop tools and technologies that contribute to poverty reduction as well as food and livelihood security. www.iwmi.org

The International Livestock Research Institute (ILRI) works with partners worldwide to enhance the roles livestock play in pathways out of poverty. ILRI research products help people in developing countries keep their farm animals alive and productive, increase and sustain their livestock and farm productivity, find profitable markets for their animal products, and reduce their risks of livestock-related diseases. ILRI is a member of the CGIAR Consortium of 15 research centres working for a food-secure future. ILRI has its headquarters in Nairobi, Kenya, a principal campus in Addis Ababa, Ethiopia, and other hubs in East, West and southern Africa and South, Southeast and East Asia. www.ilri.org

CGIAR is a global research partnership that unites organizations engaged in research for sustainable development. CGIAR research is dedicated to reducing rural poverty, increasing food security, improving human health and nutrition, and ensuring more sustainable management of natural resources. It is carried out by the 15 centers who are members of the CGIAR Consortium in close collaboration with hundreds of partner organizations, including national and regional research institutes, civil society organizations, academia, and the private sector. www.cgiar.org

The CGIAR Research Program on Water, Land and Ecosystems examines how we can intensify agriculture, while still protecting the environment and lifting millions of farm families out of poverty. The program focuses on the three critical issues of water scarcity, land degradation and ecosystem services. It will also make substantial contributions in the areas of food security, poverty alleviation and health and nutrition. The initiative combines the resources of 14 CGIAR centers and numerous external partners to provide an integrated approach to natural resource management research. This program is led by the International Water Management Institute (IWMI). www.wle.cgiar.org

Alan Duncan is a livestock feed specialist at the International Livestock Research Institute (ILRI) and joint Basin leader of the Nile Basin Development Challenge Programme (NBDC). Duncan joined ILRI in 2007 coming from the Macaulay Institute in Scotland. He has a technical background in livestock nutrition but in recent years has been researching institutional barriers to feed improvement among smallholders. Livestock-water interactions are a key issue in Ethiopia, particularly in relation to competition for water between livestock feed and staple crops. This is a core research topic for the NBDC and Duncan has built on pioneering work in this field led by ILRI’s Don Peden. Duncan manages a range of research for development projects and acts as ILRI’s focal point for the CGIAR Research Program on Integrated Systems for the Humid Tropics.

 

 

KARI agricultural innovations big hit with young smart business farmers: ‘Those are OUR people’

13th Biennial Scientific Conference at the Kenya Agricultural Research Institute (KARI) in Nairobi

 A few of the tents on the exhibit grounds at the 13th Biennial Scientific Conference held at KARI in Nairobi from 22–26 Oct 2012 (photo by ILRI/Alexandra Jorge).

The 13th Biennial Scientific Conference and Exhibition at the Kenya Agricultural Research Institute (KARI) took place last week at KARI’s headquarters in Nairobi’s leafy suburb of Loresho.

This correspondent—enamoured of the sea of white tents erected across KARI’s rolling green lawns to showcase hundreds of exhibitors of ‘Agricultural Products, Technologies & Innovations’—never actually made it to the proceedings of the conference itself. But if the conference was anything like the exhibits, it must have been a great success.

My organization, the International Livestock Research Institute (ILRI), tried to distinguish its exhibit on livestock forage research and capacity building from the hundreds of other tents just like it with decorations of African artefacts—wooden bowls, woven baskets and traditional cloths and the like—as well as safari chairs inviting passersby to come inside for a conversation. So successful were we that many people upon entering the ILRI tent promptly asked to buy some of the display items (and were promptly disappointed when we told them they weren’t for sale.) The big cattle and camel bells were also a big hit, with the visitors having to explain to ILRI staff the difference between the bell sounds appropriate for cows and those for bulls!

We were at KARI to promote opportunities for young Kenyan scientists to train at ILRI, the headquarters of which are located just a 15-minute drive from KARI. And we showcased our collaborative research with KARI scientists, including Solomon Mwendia, on disease-resistant varieties of Napier grass, aka ‘elephant grass’, on which so many Kenyan smallholder farmers depend for feeding their milk cows.

Visitors showed great interest in ILRI printed materials about improved forages and feeds (lab lab, oats, vetch), seed samples and Napier grass cuttings and leaves, and a research-based feed assessment tool for selecting appropriate feeds for different regions.

‘The demand for information was huge’, says Alexandra Jorge, who heads ILRI’s Forage Genebank, in Addis Ababa, Ethiopia, and came down to Nairobi to answer questions and provide expertise at KARI’s week-long event. ‘We had questions about the best feeds for dairy goats, how to maximize forage production for feeding dairy cows, the best methods for raising pigs, the best breeds of chickens to keep, how to transition to stall-fed (‘zero grazed’) dairy animals, how to start hydroponic and screen-house forage production, and what climate change is likely to change in Kenyan agriculture—and what livestock farmers can do now to cope with it.’

‘I really enjoyed participating in this exhibit,’ Jorge says ‘having real contact with our users and clients and chatting about their challenges and projects. It made me think hard about what we researchers do and the impact and benefits we can bring to farmers. It also made me realize how little I know about the work that many colleagues are doing and that we should make this information much more available.’

‘It was amazing to see the amount of interesting and innovative work KARI and many Kenyan universities are doing. Many people had stories to share, or tasty food, like the amazing sorghum sausages that taste just like meat!’

ILRI research manager Sandra Rwese was most impressed with the number of young entrepreneurs at this event looking for agricultural innovations and good ideas. ‘Scores of youth finding few jobs in urban areas appear to be calling city life quits and heading to rural farming villages. The numbers of these young new farmers that I met at the KARI event are much larger than I’d expected. This young generation is clearly keen on taking agriculture and livestock farming to the next level.’

Jane Gitau, a communications officer at ILRI, agrees. ‘Many of the visitors to ILRI’s tent inquiring about better methods of livestock keeping appeared to be in their thirties and early forties. They wanted information to take away with them; they wanted to learn more efficient methods of farming. It was refreshing to witness this drive to make agriculture a knowledge-based business.’

‘Walking from booth to booth’, Gitau said, ‘I was amazed to see all that KARI had to offer from its 22 centres countrywide, from Kibos to Kiboko, Muguga to Thika, each with a different mandate in agricultural research. Staff from KARI’s Kiboko Research Station, located about 150 km southeast of Nairobi and the institute’s drylands station, exhibited various imported and hybrid rangeland grasses they are trialing. KARI’s Muguga Station was exhibiting some of Kenya’s important plant and livestock genetic resources. And an improved rice variety grown under irrigation at Kibos, in western Kenya, was on display, along with rice flour, rice cakes, rice doughnuts and rice cookies!’

Finally, Gitau remarked on the close connections KARI has to its constituency. ‘Those of us manning the ILRI booth often directed visitors to the many KARI booths to get their specific farming and livestock keeping questions answered. These people sought practical help and region-specific recommendations we didn’t have’, Gitau said. ‘When I asked people if they knew where to find KARI, I several times got the reply, ‘Hao ni watu wetu’, colloquial Swahili for, “Those are our people”.

 

Livestock in the city: New study of ‘farm animals’ raised in African cities yields surprising results

Urban zoonoses and food safety: Nairobi

Leonard Gitau, a small-scale livestock farmer in Dagoretti, Nairobi, speaks to journalists during a media tour by ILRI of urban farmers in Nairobi on 21 Sep 2012 (photo credit: ILRI/Paul Karaimu).

For the first time in history, more people are living in cities than rural areas. Many of them still keep livestock. At least 800 million people in cities in developing countries practice urban agriculture, from growing vegetables to keeping camels—often in close confinement in densely populated areas.

The benefits of urban livestock keeping are many: from improved food security, nutrition and health from livestock products, creation of jobs and protection from food price volatility. But the risks in urban livestock are also large: unsanitary conditions and weak infrastructure mean that livestock can be a source of pollution and disease.

‘Zoonoses’, diseases transmitted between animals and people, are a global health problem that particularly affects the poor in developing countries. A new study by the International Livestock Research Institute (ILRI) and partners finds that zoonoses and diseases recently emerged from animals make up 26% of the infectious disease burden in low-income countries, but just 0.7% of the infectious disease burden in high-income countries.

The study, published in the journal Tropical Animal Health and Production, which was led by University of Nairobi and ILRI, is part of a series of papers that examine the facts and fiction of urban livestock keeping. The researchers note the need for evidence in the planning and practice of urban food systems and the danger of relying on perceptions or models taken from different contexts.

Here are some of the results of the study.

LOTS OF URBAN LIVESTOCK
Much more livestock is being raised in the urban areas of developing countries than most people (and policymakers) think.

THE DISEASE RISK
Domestic as well as wild animals can spread many, and some very serious, diseases to people and it is a reasonable assumption that as the population of urban areas of these and other developing countries continues to increase, the risk of zoonoses also increases.

THE GOOD NEWS
This recent in-depth study of urban zoonoses in urban environments in Nigeria and Kenya suggests that the human disease risk posed by raising, processing, marketing and/or consuming livestock in cities, city suburbs and big towns in developing countries is less than we might think.

SUPPORT INFORMAL MARKETS
Rather than bar poor people from livestock enterprises in urban areas in an attempt to protect public health, which could do the poor more harm than good, this study suggests that a more practical and equitable course is to work to enhance practices in small-scale urban livestock raising and informal livestock marketing by encouraging poor livestock producers, processors and sellers to upgrade some of their practices.

PROVIDE INCENTIVES FOR GOOD BEHAVIOUR
This study included participatory work with the local communities, and an important outcome has been the success achieved by creating incentives for the poor to improve their livestock practices rather than trying to strictly regulate these informal livestock markets, or harass the people involved, or bar them from operating altogether.

DISEASE RISKS ARE NOT WHAT WE THINK
Another important finding is that people are not the good judges of risks that they think they are; most people, including food safety officials, think that livestock foods, being so perishable, carry the greatest risk of disease in informal urban markets, but studies have shown that, for example, city vegetables are often a greater cause of disease concern than milk and meat.

TRACKING PATHOGENS AND RELATED ILRI RESEARCH
This research project was conducted jointly with the University of Nairobi, whose Professor Erastus Kang’ethe led the data collection and participatory work within Kenya, with the support of the Kenyan government and health officials. This project also expands ILRI’s long-standing research on informal dairy markets in East Africa and South Asia, led by ILRI scientist Amos Omore and others, which helped to refine dairy policies to support rather than harass sellers of ‘raw’ (unpasteurized) milk. And a new ILRI research project led by ILRI scientist Eric Fevre will investigate zoonoses further by tracking disease pathogens as they move among farms, processors and markets in Nairobi.

Urban zoonoses and food safety: Nairobi

ILRI scientist Delia Grace is interviewed by BBC and AllAfrica.com before the start of a journalist tour of urban livestock farmers in Nairobi that ILRI organized on 21 Sep 2012 (photo credit: ILRI/Paul Karaimu).

Delia Grace, an ILRI veterinary epidemiologist and leader of a component of the CGIAR Research Program on Agriculture for Nutrition and Health, was the principal investigator in the Ibadan-Nairobi zoonoses study and editor of this special edition of Tropical Animal Health and Production. Grace says that regulations that work for rich countries do not always work for poor countries, and that policies should follow a risk-based approach where decision-makers’ focus is not the bugs present in food but the likely effects on human health. ‘The risks of food-borne diseases’, she says, ‘need also be weighed against the economic benefits and nutrition abundantly supplied by animal products.’

In the absence of evidence, policies are based on the prejudice that urban livestock keeping is unsafe and unmodern, and it is often banned outright. Of course it continues behind hedges and in back alleys, but the imposed illegality drives a rush to the bottom in hygienic practices and investments. When farmers are harassed by authorities and operate in a legal grey area, they have little access to the support they need and little incentive to invest in business improvements.

Thanks in part to previous research on the benefits of urban agriculture, the Government of Kenya has been proactive in posting veterinary, animal production, and crop personnel in major urban centers to lead from the front in championing the development of urban agriculture. The government has also led in the development of the urban agriculture and livestock policy. Involving these civil servants has been key in enabling our research in urban agriculture. This is a good example of government changing its policy to better meet the needs of citizens.

Rapid urbanization, and along with it the urbanization of poverty and food insecurity, raises urgent challenges for the global research and development community. Among them is the need to manage the growing risks of zoonosis associated with urban farming and to improve food safety for the one billion of the world’s poor living in cities, most of whom depend on informal markets instead of more formal government-organized markets or grocery stores.

Informal, or wet markets, exist in many different forms across Africa and Asia but have common characteristics: food escapes effective health and safety regulation; many retailers do not pay tax and some are not licensed; traditional processing, products and retail practices predominate; infrastructure such as water, electricity, sanitation, and refrigeration is lacking; and little support is provided from the public or non-governmental sector. Unsurprisingly, women and the poor are involved most in informal markets.

Applying an innovative research approach known as ‘ecohealth’, the findings of this research contradict some basic assumptions about zoonoses and urban farming and show how livestock keepers in one of Africa’s biggest cities, Nairobi, Kenya, are transforming their livestock and public health practices to combat disease and help feed a city where 60% of the population lives in slums.

But what does it mean in practice? A special edition of 11 papers sets out how ecohealth approaches can make a difference to city health. The researchers base their findings from two case studies. One is in Dagoretti, a Nairobi district of some 240,000 residents, and analyzes the emerging zoonoses cryptosporidiosis, a diarrhoeal disease that is passed from cattle to humans.
