This briefing paper is one of the 10-part Global Development Network (GDN) Agriculture Policy Series for its project, ‘Supporting Policy Research to Inform Agricultural Policy in Sub-Saharan Africa and South Asia’. It is based on a longer synthesis paper, Long-term challenges to food security and rural livelihoods in Sub-Saharan Africa, which draws on extensive published and unpublished research. It will be of value to policymakers, experts and civil society working to improve agriculture in Sub-Saharan Africa. A total of 180 million food-insecure people live in Sub-Saharan Africa, over 21 per cent of the African population. These are among the world’s most vulnerable people, poorly equipped to respond to the threat of climate change, demographic stresses, or spikes in global food prices. This briefing examines how improvements in agriculture might help to achieve g

The study assesses the types and quantities of direct non-timber forest products (NTFPs) extracted by the local people living around the Kakamega Forest in Western Kenya. It further analyses the factors that influence a household's decision to participate in NTFPs' collection and the level of extraction undertaken. The results of this study are derived from a stratified sample of 370 households who were interviewed with a semi-structured questionnaire. The quantities of the different products obtained by extracting households are valued at the average market prices to obtain their financial values. The results of the study indicate that the forest generates a substantial economic value to the local people. It was found that this value is comparable to that of the common crop enterprises in the research area. A Heckman two- stage regression model is used to analyse the socio-economic, institutional, and geo-physical factors that influence the household decision to participate in forest extraction and the quantities of the different products obtained. Proximity to the forest edge, the form of forest management approach, age and education level of the household head, household private land holding and participation in forest conservation activities are the main factors influencing the household decision to extract NTFPs from the forest. The level of extraction for the participating households is influenced by their proximity to the forest, the household size, participation in forest conservation activities and whether the household uses the extracted forest products as a source of income. The study concludes by highlighting some important policy inferences for sustainable use and conservation of Kakamega Forest.

Abstract This study analysed the factors influencing the intensity of adoption of improved fallows in Western Kenya. Three hundred farmers were interviewed. Descriptive results showed the adopters to be older, more educated and had more contact with technology promoters than the non-adopters. Partial budgets were constructed and marginal rates of returns (MRR) showed that the technology is profitable. Based on the censored Tobit, the results indicate that the intensity of adoption was significantly influenced by age, experience of the household head and spouse, total land area, contact with technology promoters, technology profitability and use of other soil fertility replenishment options. It is recommended that education efforts be intensified. There is need to strengthen contact with the technology promoters. In order to ensure information flow to all, there is need for improvement in the approach and methods employed in on-farm research. Further, there is need to establish and strengthen networks of information exchange among relevant and interested organisation

The agricultural economies of Africa have witnessed three major changes during the past 10 to 15 years that justify a reassessment of agricultural research priorities. First, liberalization of macroeconomic and trade policies has increased the relative importance of tradeables in the commodity mix. Second, agricultural input and product markets have expanded, broadening the range of livelihood strategies available to rural households. Finally, broader partnerships for technology development and dissemination are creating new opportunities. Many of Africa’s poorest and most food-insecure farmers live in semiarid areas. To survive in a harsh and variable environment, they pursue a range of livelihood strategies. Different households pursue different development paths. But almost all seek to diversify their income sources and investment strategies as a means to reduce risk and respond to changing market conditions. How can R&D agencies improve the payoffs to farmers’ investments? There are trade-offs between different alternatives – should the farmer spend her limited money looking for an off-farm job, or on livestock, or on a bag of fertilizer? It is hard to evaluate these trade-offs. But recent investment trends offer some clues on the trade-offs involved, and on how farmers’ investment decisions are influenced by changes in policy, technologies, and market conditions. In July 2002, ICRISAT sponsored a conference on Targeting agricultural research for development in the semi-arid tropics of sub-Saharan Africa to discuss how best to link technology development, market expansion, and agricultural growth in Africa’s semiarid tropics (SAT). This meeting • Examined and compared alternative growth paths for poverty alleviation and development of smallholder agriculture • Reviewed the market and institutional factors influencing technology adoption • Assessed the current stock of available technologies • Discussed institutional arrangements linking national and international research programs and the public and private sectors. The meeting concluded with a series of recommendations for better targeting of agricultural research to achieve faster development. This policy brief summarizes the discussions and outputs from the meeting.
