| Maize is the staple food for most Kenyan households, and grown in almost all the farming systems. Due to diminishing farm sizes in Kakamega District, crop productivity and the efficiency of farming systems are of great concern. This paper aims to provide empirical evidence on the links between efficiency in maize production and access to soil-related agricultural information services. Using cluster sampling, a total of 154 farmers in Kakamega District were interviewed. A 2–step estimation technique (Data Envelopment Analysis (DEA) and Tobit model) were used to evaluate the technical efficiencies among the farmers and the factors explaining the estimated efficiency scores. Data was disaggregated into farmers with and those without access to soil-related... |

| This study is based on micro level data on urban household food consumption and expenditure collected between 1999 and 2000 in three Nigerian cities. The LA/AIDS model, which allows the inclusion of demographic variables, was applied to a subset of the data on meat and meat products namely beef, mutton/goat, chicken, fish, eggs, and milk. Results indicate that urban demand for meat products will continue to increase as incomes improve, suggesting potential market opportunities especially for poultry. Intra-household demand patterns clearly indicate the importance of beef for children but contrary to expectations, there is a reduced demand for milk as the number of infants in urban households increase. The observed high income elasticity of demand for... |

| The push-pull technology (PPT) has widely been disseminated to control stemborer (Chilo partellus and Busseola fusca) and Striga weeds (Striga hermonthica and Striga asiatica) in maize fields in Kenya. This study examined farmers’ preferences for various dissemination pathways in order to proffer better targeting of resources in an optimal dissemination strategy. The pathways considered were public meetings (barazas), radio, farmer field schools (FFS), field days (FD), farmer teachers (FT), the fellow farmers (FF) and print materials. Using a weighted score index and ordered probit regression, the different pathways were sequentially ranked as FD, FT, FFS, FF, print materials, Radio, and barazas. Marginal effects from ordered probit showed that farmers had... |
