With the potential threat of more frequent climate extremes putting semi-arid crop production in jeopardy, there is a need to establish more climate resilient cropping practices. Intercropping is often practiced by farmers in semi-arid regions and is perceived as a risk reducing practice. However...

This paper addresses the need for more rigorous evaluation of climate service projects and investments given theexistence of little evidence on the actual value of climate services and the challenges that hamper current effortsto evaluate the impact of climate services for the agricultural communi...

Impact studies assuming exogenous technology adoption are bound to overstate or understate the true impact of improved agricultural technologies, especially in situations where agricultural technologies are targeted to, or adopted by, a certain group of farmers. This paper examined the impact of ...

Plantain is an important staple in West and Central Africa, where it is predominantly grown by smallholder farmers. On-farm data are rare but yields are considered to be low. We collated actual yields in the region, reviewed regional plantain research published from 1976 to 2013, then estimated w...

An assessment of post-harvest handling practices and food losses in a maize-based farming system in semi-arid areas of Central and Northern Tanzania was carried out in 2012. Seventeen crops were mostly cultivated by the farmers in the surveyed areas; maize (32%), sunflower (16%) and pigeon peas (...

Maize infected by aflatoxin-producing Aspergillus flavus may become contaminated with aflatoxins, and as a result, threaten human health, food security and farmers’ income in developing countries where maize is a staple. Environmental distribution and genetic diversity of A. flavus can influence ...

Labour productivity affects food security, but quantifying this relationship has been scarce with respect to empirical literature. The Central Madagascar dataset explores the influence of labour productivity and related variables on the food security status of cassava farmers. Drawing on both the...

Cassava brown streak disease (CBSD) has emerged as the most important viral disease of cassava (Manihot esculenta) in Africa and is a major threat to food security. CBSD is caused by two distinct species of ipomoviruses, Cassava brown streak virus and Ugandan cassava brown streak virus, belonging...
