Over 80 per cent of Kenya’s milk output is produced by close to 800,000 smallholder dairy farmers in a sector that also has 350,000 smallholder milk vendors. In recent years, Kenya’s dairy sector has experienced a major growth in milk production as a result of various programs that have streamlined the industry and given support to dairy farmers and the country’s milk value chain that ties producers to sellers to consumers.

One such initiative is a Smallholder Dairy Project, which worked with the country’s dairy farmers between 1997 and 2005. The project was implemented by the Government of Kenya, the Kenya Agricultural Research Institute and the International Livestock Research Institute (ILRI) together with other partners.

In this 7-minute film, produced by WRENmedia, Margaret Lukuyu, who was part of ILRI’s team in the project (she now works with the Kenya Agricultural Research Institute), talks about how small-scale milk vendors in Kenya have improved the ways that they handle milk, which has resulted in higher profits for them. She says the sellers have also increased their milk supply to consumers in an industry that contributes about 4 percent of total national gross domestic product (GDP).

One of the key successes of the project was the licensing of smallholder milk traders and farmers in the ‘informal milk sector’ into various registered groups, such as the Kenya Smallholder Milk Traders Association, which has empowered both farmers and traders to lobby for needed policy changes. This project played a key role in reforming Kenya’s national dairy policy and increased support for the country’s massive ‘informal milk sector’, which trades in unpasteurized (‘raw’) milk. 

The film also highlights the experiences of Teresa Kamau, a business developer who trained farmers and traders in business management skills as part of the project, and Gabriel Karanja, a milk trader who has seen increased returns as a result of his sales of clean and higher-quality milk.

Livestock researchers say the traditional knowledge of local pastoralists in East Africa needs to be included in programs to better control livestock diseases in the region.

Somali and Maasai herder early warning systems both were key in identifying the risk factors and symptoms of Rift Valley fever in an outbreak in 2006/7.  

Rift Valley fever is an acute viral zoonosis spread by mosquitoes. It primarily affects domestic livestock such as cattle, camels, sheep and goats, but can also infect, and kill, people, especially those handling infected animals.

First isolated in humans in the Rift Valley region of Kenya in 1930, until the 1970s Rift Valley fever was reported mainly in southern and eastern Africa, primarily Kenya, where it was considered an animal disease, despite sporadic human cases. But after the 1970s, explosive outbreaks occurred in human populations throughout Africa, Indian Ocean states and the Arabian Peninsula. Epidemics in Egypt in 1977/8 and in Kenya in 1997/8 each killed several hundred people. Another outbreak in Kenya in 2006/7 killed more than 100 people.

In East Africa, Rift Valley fever outbreaks have coincided with heavy rainfall and local flooding, which can lead to expansion of mosquito populations. In an assessment made to review lessons from the 2006/7 outbreak in East Africa carried out by scientists from the International Livestock Research Institute (ILRI) and the Kenyan and Tanzanian departments of veterinary services, researchers found that Somali pastoralists of northeastern Kenya accurately assessed the likelihood of an outbreak based on their assessments of key risk factors, and they did so long before veterinary and public health interventions began. The study also looked at the experiences of Maasai herders of northern Tanzania, who accurately recognized symptoms such as high abortion rates as indicating the presence of the infection in their herds.

Among the environmental factors the Somali communities noticed as likely to lead to an outbreak is an increase in rainfall (usually accompanied by floods) and an increase in mosquitoes. Both preceded the 2006/7 outbreak and had been present in the last outbreak of Rift Valley fever in the region in 1997/8. The Somalis also accurately associated a ‘bloody nose’, or Sandik, in their animals with Rift Valley fever.

The role of this traditional knowledge in predicting Rift Valley fever is the subject of a paper, ‘Epidemiological assessment of the Rift Valley fever outbreak in Kenya and Tanzania in 2006 and 2007’, published in the August 2010 supplement of the American Journal of Tropical Medicine and Hygiene.

The authors say that Somali pastoralists are particularly able to predict not only the symptoms of Rift Valley fever in their animals but also the likelihood of an outbreak of the disease. Indeed, observations by local communities in risk-prone areas were often more timely and definitive than the global early warning systems in use at the time of the 2006/7 outbreak.

‘Timely outbreak response requires effective early warning and surveillance systems. This study points out the important role that livestock keepers can play in veterinary surveillance,’ the authors say.

As a result of the experiences of the 2007 outbreak, the authors recommend adopting new forecasting models and surveillance systems ‘that place more emphasis on climatic information [to] increase the lead time before events and enhance the ability of decision-makers to take timely action.’

The researchers also say that outbreaks of Rift Valley fever could be managed better if disease control workers were able to run models that combined economic with epidemiologic factors. With such models, they could better determine the benefits of implementing various disease surveillance and control methods, and the best times to implement each method selected for each circumstance.

A related ILRI news article addresses the full effects of the 2006/7 Rift Valley fever outbreak in East Africa, including the national and regional socioeconomic impacts of the outbreak and its effects on human and animal health.

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.'

The genetic diversity of African livestock is increasingly under threat as indigenous livestock varieties are cross-bred, or slowly replaced, with exotic breeds that produce more milk and meat. Exotic livestock varieties are, however, less resistant to African environmental and climatic challenges and are also less resistant to endemic diseases like trypanosomosis (called ‘sleeping sickness’ in people).

The following 3-minute film highlights an initiative supported by the International Livestock Research Institute (ILRI) in Uganda that is working to conserve purebred Ankole cattle, a breed native in eastern Africa and relied upon by farmers in at least four countries.

In the film, Daniel Semambo, Director of Uganda’s National Animal Genetic Resources Centre and Data Bank, outlines the issues facing many developing countries as they try to improve their livestock productivity and at the same time they try to stem losses of their native livestock breeds and genes.

Women in rural areas have a heavy workload that included delivery of food, water and fuel for household needs

New research findings on bioenergy access and delivery in Kenya are recommending greater collaboration between stakeholders to promote sustainable use of bioresources, biofuels and bioresidues.

In a socioeconomic baseline survey carried out by the eastern Africa office of Practical Action Consulting, in Kenya, between March and December 2008, researchers evaluated the bioenergy needs, gaps, status and opportunities for poor people in Kenya. The research focused on the socioeconomic links and patterns of bioenergy use, access and delivery for the poor in Kenya and generated baseline data that can guide national decision-making.

The report, ‘Bioenergy and Poverty in Kenya: Attitudes, Actors and Activities’, looks at bioenergy use and access by communities in Kenya, with information collected from Kisumu, Lodwar, Mandera, Nairobi and Nakuru.

The report says more awareness of alternative bioenergy technologies and resources is needed in Kenya’s rural and peri-urban areas. It recommends training communities in producing and using low-cost energy-saving stoves and in planting trees. The long-term impacts of firewood and charcoal use by households and institutions should be better known, the report says, and charcoal use should be matched by tree replanting.

The report also calls for a change in attitudes regarding female provision of household fuel; such provision must begin to be seen, say the researchers, as a joint responsibility of all family members. And development programs should begin to treat energy and gender as central, not peripheral, issues in development.
