Goat plague next target of veterinary authorities now that cattle plague has been eradicated

Last known occurrences of rinderpest since 1995. IFPRI Discussion Paper 00923, November 2009, ‘The Global Effort to Eradicate Rinderpest’ by Peter Roeder and Karl Rich, 2020 Vision Initiative, a paper prepared for a project on Millions Fed: Proven Successes in Agricultural Development (www.ifpri.org/millionsfed) (illustration credit: FAO GREP).

Jeffrey Mariner, former advisor for special action areas to the Pan-African Rinderpest Campaign and current senior scientist at the International Livestock Research Institute (ILRI), based in Kenya, is one of several authors of a paper published in the current issue of Veterinary Record on the subject of the rising importance of building a systematic program to eradicate a goat disease known as ‘peste des petits ruminants’ (PPR), or goat plague.

The editorial in the Veterinary Record explains why goat plague is replacing cattle plague among the world’s verterinary researchers.

‘This week saw a landmark in the history of the veterinary profession and, more specifically, its management of disease threats to food security. The Food and Agriculture Organization of the United Nations (FAO) announced on June 28, 2011 that its member countries had passed a resolution declaring rinderpest to have been eradicated globally, building on an announcement in May that the World Organisation for Animal Health (OIE) at its General Session had passed a resolution to the effect that all countries in the world had been formally accredited as free from rinderpest.

‘These events mark the fact that the virus is no longer present in any of its natural hosts on this planet. No longer is it a cause of disease or a constraint to international trade. What is not generally appreciated is that the eradication of rinderpest has yielded benefits that surpass virtually every other development programme in agriculture, and will continue to do so into the future. For example, a preliminary study in Chad shows that over the period 1963 to 2002, each dollar spent on rinderpest eradication led to a benefit of at least US $16, a conservative estimate that only takes into account the benefits from reduced cattle deaths and resulting herd growth, without including secondary impacts on the economy as a whole (Rich and others 2011).

‘Building on the dramatic success of the global effort to eradicate rinderpest we now wish to draw attention to a related but significantly different morbillivirus disease, peste des petits ruminants (PPR), also known variously as goat plague, pseudorinderpest, pneumoenteritis and kata. A comprehensive review of the disease by research scientists at the Institute for Animal Health Pirbright laboratory (IAH Pirbright) is published in this issue of Veterinary Record and explains the scientific basis for considering eradication (Baron and others 2011).

‘Until relatively recently PPR was considered to be a parochial disease of west Africa; however, its range is now recognised to affect most of sub-Saharan Africa as well as a swathe of countries from Turkey through the Middle East to south Asia with recent alarming extensions into north Africa, central Asian countries and China. Capable of causing very high mortality in susceptible goat herds and sheep flocks, PPR exerts a major economic impact on farmers and their families dependent on small ruminants. There is a growing appreciation that PPR is a most serious constraint to the livelihoods of farming families and to food security in affected countries and that its control warrants significant investment. An additional concern is the lethal nature of PPR infection in wildlife species, many of which are endangered or threatened, including gazelles and mountain caprines. Until recently, losses were apparently restricted to extensive wildlife collections in the Middle East but now outbreaks are being recognised in free-ranging species such as the Sindh ibex (Capra aegagrus blythi) in Pakistan. It is probable that many cases of wildlife disease have passed unnoticed in remote locations.

‘Encouraged by what has been achieved with rinderpest and an understanding that the factors that marked rinderpest eradication as feasible apply equally to PPR, we believe that a global programme for the total eradication of PPR should be established as an international undertaking without delay. The FAO has recently hosted a number of symposia and workshops at which participating chief veterinary officers have unanimously requested such a global initiative against PPR. . . .’

Amid soaring meat costs, officials from East Africa and Middle East seek plan to keep animal diseases from disrupting livestock trade

With increased trade in livestock products offering a possible antidote to high food prices, livestock experts from the Middle East and 12 African countries are meeting this week (13-16 June, 2011) in Dubai to develop a strategy that eliminates the need to impose devastating bans on livestock imports from the Horn of Africa, as prevention against the spread of Rift Valley fever. The strategy should expedite the flow of livestock products while increasing safety of the overall livestock trade in the region.

Convened by the African Union’s Interafrican Bureau for Animal Resources (AU-IBAR), the International Livestock Research Institute (ILRI) and the United States Agency for International Development (USAID), the workshop will encourage officials and livestock traders to use a simple ‘Decision Support Planning Tool’ to guide and moderate their responses to Rift Valley fever outbreaks.

The ‘decision support tool’ for Rift Valley fever was developed by 30 experts and decisions-makers from across the Horn of Africa with technical assistance from researchers at ILRI, the United Nations’ Food and Agriculture Organization (FAO), and other partners. The tool will be used by chief veterinary officers and other national decision-makers. Its framework identifies the sequence of events likely to occur as the risk of a disease outbreak increases.

Rift Valley fever is a mosquito-borne virus found in eastern, western and southern Africa, Yemen and Saudi Arabia. Epidemics emerge periodically with prolonged rains. Climate and land-use changes could make outbreaks more frequent. A study done by ILRI economists Karl Rich and Francis Wanyoike indicated that the Rift Valley fever outbreak in 2007 cost Kenya at least USD32 million.

‘We must avoid unnecessary disruptions in agricultural trade between East Africa and the Middle East,’ said Ahmed El Sawalhy, director of AU-IBAR. ‘Livestock products must be safe and action concerning disease outbreaks must be in line with the actual threat.’ To this end, an animal health certification model suitable for pastoral livestock production systems and that promotes OIE standards has been developed by AU-IBAR in partnership with FAO and the Royal Veterinary College, London. The model is based on risk assessment and involves integration of both upstream animal health inspection and certification at entry points, markets and at the quarantines.

Time is also of critical importance in prevention and control of transboundary animal diseases. ‘In the last Kenyan Rift Valley fever outbreak, control measures were implemented late—not until there were definitive signs of an outbreak,’ said Jeffrey Mariner, an epidemiologist at ILRI. ‘This tool links early warning signs to control measures that can be implemented before animals or people begin falling ill. The new tool could reduce the impact of Rift Valley fever, and maybe even prevent some local outbreaks and has the potential to prevent the spread of Rift Valley fever through trade.’

‘The good news,’ says Bernard Bett, an epidemiologist at ILRI, ‘is that the impact of Rift Valley fever can be mitigated with early action during an outbreak, but veterinary officers and  decision-makers need to know what interventions to implement—and when—as the  stages of an epidemic  unfold.’

Rift Valley fever is best prevented through animal vaccination. But vaccines are expensive and few governments are willing to pay for expensive vaccines unless evidence indicates an epidemic is imminent. Regional cooperation is required to build consensus on managing the disease and to prevent trade disruptions.

Larry Meserve, USAID/EA’s regional mission director commented, ‘President Obama’s Feed the Future initiative aims to increase food security throughout Africa. To succeed, we must all help to improve the capacity of leadership in the Horn of Africa to anticipate potentially disastrous events like disease epidemics so that appropriate preventive or mitigating measures are taken before it is too late. Livestock is a vital staple crop in this part of the world, and both the private and public sectors have to do everything possible to prevent unnecessary disruptions in the trade of livestock and other commodities.’

How do we get more poor people into the world’s vibrant and emerging livestock markets?

Mozambique, Maputo

Across much of the world, especially in developing countries, market opportunities for livestock products are increasing rapidly as a result of rising demand for animal products driven by growing populations, rising incomes and urbanization. These new markets have created opportunities for smallholder livestock producers, including poor rural farmers, to benefit from ready markets for milk, eggs and meat. But as markets expand, they also often give way to complex supply and distribution channels and the need for high-value products that can end up locking out smallholders from enjoying the benefits of these expanding markets.

How do smallholders maintain their ability to contribute to and benefit from the complex systems that will inevitably result as livestock markets grow?

According to researchers John McDermott and Berhanu Gebremedhin, from the International Livestock Research Institute (ILRI), and Karl Rich and Heather Burrow, from the Norwegian Institute of International Affairs and the University of New England, Australia, respectively, assessing existing relationships in these increasingly complex livestock value chains can not only reveal the reasons behind the increasing complexity of these systems, but also identify potential opportunities for smallholders and show policy and other constraints that can be addressed to encourage more of them to engage in the markets.

In findings presented in 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 Rural Cooperation (CTA) and ILRI, the researchers suggest areas that can be improved to encourage smallholder participation in livestock value chains. These include ‘local and informal markets, which offer the primary initial growth potential in poor countries’ and post-production systems such as that for processing manure for fuel and for processing hides and skins, which can provide important value addition for smallholders.

Smallholders are best at managing informal production environments, where they can make good use of household labour and low-cost production inputs. The authors cite widespread successful smallholder dairy production systems in South Asia, East Africa and Latin America, which are thriving.

This book reviews how smallholders are participating in emerging and growing livestock markets in Ethiopia and South Africa. The authors note that smallholder participation in livestock markets is particularly influenced by whether organizations within the livestock value chain encourage smallholders to join their organizations, which promotes ‘chain-level interventions that give opportunities for smallholders to participate in markets’.

In Ethiopia, for example, the emerging dairy market is served by farmer organizations like the Ada’a Cooperative in Debre Zeit, an hour’s drive from Addis Abba, which is working to provide feeds and animal health services to members, to improve local dairy breeds and milk collection and to introduce value-added processing. These efforts have led to a tenfold increase in milk collection, to 2.6 million litres, between 2000 and 2005, a gradual strengthening of smallholder links to markets, and a growing demand for breeding and feeding services, which are starting to be met by private companies.

‘There is evidence that setting up and maintaining strong organizations to manage market chains not only leads to improved economic benefits for producers but also leads to broader social benefits like gender development and education,’ the authors say. They recommend improving animal breeds, improving animal nutrition and integrating input supplies and knowledge and financial and market services into the market systems. ‘Smallholders are more likely to benefit from market initiatives when these markets are oriented towards sellers, where enabling policies from government exist and where collective action and support is mobilised . . . .’

‘Commodity-based trade approaches’ also help to bring more smallholders into the market. In Ethiopia, for example, a phased export program for beef that allows quarantine, vaccination and disease control followed by observation in an export-zone feed lot before slaughter has provided a way of certifying meat as disease-free for export to Middle Eastern markets.

The authors warn, however, that not all livestock value chains will be accessible to smallholders. Few of Africa’s small producers export beef and other meat because these products are governed by unique tariff systems and international trade rules and are open to international competitors.

The book recommends regular review of the performance of value chain systems to ensure they are responsive to both small-scale producers and changing consumer demands.

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.

Assessing the full costs of livestock disease: The case of the 2007 outbreak of Rift Valley fever in Kenya

Rift Valley fever is a mosquito-transmitted zoonotic disease that harms both human health and livestock production. It can also induce large, often overlooked, economic losses among many other stakeholders in the livestock marketing chain.

A new paper published by ILRI scientists Karl Rich and Francis Wanyoike assesses and quantifies the multi-dimensional socio-economic impacts of a 2007 outbreak of Rift Valley fever in Kenya. The study is based on a rapid assessment of livestock value chains in the northeast part of the country and a national macroeconomic analysis. As would be expected, the study results show losses among producers in food security and incomes. But the researchers also found significant losses occurred among other downstream actors in the value chain, including livestock traders, slaughterhouses, casual labourers, and butchers, as well as among those in non-agricultural sectors. To better inform policy and decision making during animal health emergencies, the authors argue that we should widen our focus to include analyses that address the multitude of economic losses resulting from an animal disease.

The authors write:

‘Rift Valley fever has had significant impacts on human and animal health alike in East Africa and the Middle East. Past outbreaks in South Africa (1951), Egypt (1977/78), Kenya (1997), and Saudi Arabia (1998–2000) resulted in the cumulative loss of thousands of human lives. The 2000 outbreak in Saudi Arabia led to the imposition of trade bans of live animals from the Horn of Africa (Ethiopia, Somalia, and Kenya) that had devastating economic impacts: one study estimated that total economic value-added in the Somali region of Ethiopia fell by US$132 million because of these trade bans, a 42% reduction compared with normal years . . . .

‘In 2007, Rift Valley fever returned to East Africa, impacting both Kenya and Tanzania. Specifically hard hit by this latest outbreak were the pastoral communities of the northeastern part of Kenya. In this region, livestock serve an important livelihood function for pastoralists, with livestock trade representing over 90% of pastoral incomes . . . . Moreover, northeastern Kenya has the highest incidence of poverty within Kenya, with poverty rates of approximately 70% in 2004 . . . .

‘An overlooked component in the socio-economic analysis of animal diseases is the multiplicity of stakeholders that are affected. Rift Valley fever does not just affect producers, but also impacts a host of other service providers within the livestock supply chain and other parts of the larger economy. Cumulatively, these downstream impacts can often dwarf the impacts of the disease at the farm level, but public policy tends to concentrate primarily on losses accruing to producers. The failure to capture these diverse impacts may have important implications on the evolution and control of disease that may accentuate its impact.

‘The 2007 Rift Valley fever outbreak in Kenya had wide-ranging impacts on the livestock sector and other segments of the economy that are often overlooked in the analysis of animal disease. These impacts included production impacts, employment losses (particularly for casual labor), and a reduction in operating capital among slaughterhouses and butchers that slowed the recovery of the livestock sector once the disease had abated. On a macroeconomic basis, we estimated that Rift Valley fever induced losses of over Ksh 2.1 billion (US$32 million) on the Kenyan economy, based on its negative impacts on agriculture and other sectors (transport, services, etc.) alike.’

African meat for global tables

Mozambique, Maputo

As new channels for African exports become increasingly available, economists and policy makers are focusing more attention on how best to match producers to buyers in Europe and elsewhere, including Africa itself. A recent paper explores the potential and pitfalls of exporting African livestock products.

‘What can Africa contribute to global meat demand?’ recently appeared in Outlook on Agriculture (Vol 38 No 3, pp. 223-233, September 2009). It is authored by Karl M Rich, who works with both the International Livestock Research Institute (ILRI) and the American University in Cairo, and will move to the Norwegian Institute of International Affairs (NUPI) in Oslo, Norway, in February 2010.

Observing that global demand and prices for meat are currently at unprecedented highs, Rich cites International Food Policy Research Institute (IFPRI) data that project that annual per capita meat demand in Africa will double to 22 kg by 2050. This increase will necessitate corresponding rises in demand for cereals as well as livestock. Estimates from the Food and Agriculture Organization of the United Nations (FAO) suggest similar increases in demand throughout the developing world.

These increases bring new opportunities for alternative sources of supply. At first glance, it would seem that Africa would have a distinct advantage in meeting the increasing demand within the continent. However, Africa’s ability to compete with Europe, Asia and the Americas has historically been constrained by low productivity, prevalence of animal diseases and the difficulty of meeting high global standards for health and safety. These constraints must be addressed before Africa can become a major player, and Rich’s paper examines the possibilities of bringing this happy situation about.

Rich begins with an overview of Africa’s role in the global meat trade, both imports and exports. His efforts in this regard are nothing less than heroic. The data from each of Africa’s fifty-odd countries are accumulated in enormously different ways, and the most recent data for some countries are several years old. Nonetheless, the figures are important, and to date no other author has made comparable efforts to get a handle on the situation. Rich does not express a great deal of optimism for the short or medium term. He estimates, for example, that at present Africa provides only about 1% of global meat exports for beef, pork and chicken.

A comparison of regional export shares is even more daunting. Table 1, which presents FAO data, indicates that the overwhelming majority of products come from southern Africa, notably South Africa, Botswana and Namibia, while goat and pig products are sourced predominantly from East Africa. Sheep products come mainly from North Africa (mainly Sudan). Meat exports from the rest of Africa, especially Central and Western Africa, are miniscule. Eight other tables and five figures in the paper provide detailed information of the variety and amount of meat imports and exports among African countries. In the case of exports, information is provided concerning the countries importing African meat products.

Among significant competitor nations are the emerging giant economies of the developing world, especially Brazil and India. These two countries account for a huge slice of the African market, constituting the main source of beef imports—both frozen and fresh—to seven of the largest African customer countries.

Rich points out that one important advantage that India, Brazil and other Latin American countries (Argentina, Paraguay, Uruguay) have over Africa is scale. According to the most recent data from FAO (2006), the total stock of cattle in Africa is about 232 million head. By contrast, Brazil alone has over 207 million head, while India has 180 million as well as nearly 100 million head of buffalo. The African countries with the largest stocks are Ethiopia and Sudan, but neither comes close to those of Brazil or India, and both have fewer head than Argentina.

While African exporters will not be able to compete with Brazil or India in the short to medium term, inroads to foreign markets have been made by some southern African countries to the European Union (EU). This trade is driven by preferential access to the EU brought about through the Cotonou Agreement which provides tariff reductions for African and other developing economies. But even with such international agreements in place, African countries have been unable to fill the quotas provided, largely because of the rigourous standards for compliance with EU sanitary regulations. To retain access to European markets, for example, Botswana and Namibia have had to set aside areas free from foot and mouth disease (FMD)—an expensive arrangement that precludes raising cattle by traditional African husbandry methods. Furthermore, without these preferences it is unlikely that southern African producers could compete with the likes of Brazil.

Rich concludes his paper with a section entitled The road ahead: where and how can Africa contribute to global meat demand?  Before discussing the most likely methods for improving Africa’s competiveness with other meat-exporting nations, however, he cautions that ultimately, significant improvements in productivity, breeding, infrastructure and marketing will be required over and above the options he identifies.

The author identifies five options.

  1. Commodity-based trade. Diseases such as FMD persist in developing countries, limiting market access from developing markets to lucrative ones in the developed world. Commodity-based approaches focus on attributes of a product such as quality and safety rather than the disease status of its place of origin. It is argued that deboned and properly matured beef, for example, poses virtually no threat of transmission of diseases such as FMD. While commodity-based approaches could pave the way for increased trade from Africa, a number of gaps remain. In particular, will African countries be the major winners? If not, what further constrains Africa’s market access? A recent report by Karl Rich and Brian Perry to the UK Department for International Development explores this option further.
  2. Certification programs and disease-free compartments. Africa can raise its profile in global markets by demonstrating compliance with SPS standards. A compartment is a network of micro-level disease-free areas linked to each other and maintained through high levels of monitoring. A good example of this option is discussed in the paper mentioned in the box item above, a USAID-funded program currently under way in Ethiopia.
  3. Branded niche products. This option focuses on the strengths that Africa can offer global buyers by building and encouraging trade associations and marketing organizations. The author cites several examples—Farmer’s Choice of Kenya, Farm Assured Namibian Meat, the Kalahari Kid Corporation, the Namibian Meat Board, the South African Meat Industry Company and the National Emergent Red Meat Producers Organisation. These associations promote local products, engage in branding and quality assurance and build the capacity of emerging farmers.
  4. Regional integration and trade. Rich points out that despite the existence of regional cooperation agreements, barriers between member countries continue to hamper trade. Reducing these barriers will be crucial if Africa is to develop and harness the scale necessary to compete in international markets and lower costs. Investments in marketing and promotion among regional partners will be required for countries to enter and sustain effective trading in high-value markets.
  5. Domestic markets. Both formal and informal channels for meat products have been developed within each African country over the past several years. Because domestic prices in fact frequently exceed international prices, finding ways to deliver local products at competitive prices is an option with good potential, though these products will increasingly compete with low-cost imports. Competing effectively on price will be crucial for African producers to be successful in such channels.
