Maize is becoming increasingly important as a food security crop in West Africa. However, recurring droughts constitute a continuous challenge to its production. Attempts at addressing the drought problem resulted in the conduct of a participatory community survey of maize production systems with about 20–40% probability of drought risk in four DTMA countries (Bénin Republic, Ghana, Mali, and Nigeria). The project is part of an initiative to develop and disseminate appropriate drought tolerant maize varieties in sub-Saharan Africa. The main objectives of the community survey were to complement household survey data, capture essential qualitative information and data that are difficult to obtain through formal household surveys, and serve as a pilot application for potential expansion through the African region. The survey was conducted in selected communities in two districts with high levels of maize production in each of the DTMA countries.

In sub-Saharan Africa (SSA), "maize is life," due to its importance to food security and economic wellbeing. Around 40 % of Africa’s maize-growing area faces occasional drought stress, resulting in yield losses of 10–25 %. Around 25 % of the maize crop suffers frequent drought, with losses of up to half the harvest. To reduce vulnerability and improve food security, the Drought Tolerant Maize for Africa (DTMA) project has made releases of 160 drought tolerant (DT) maize varieties between 2007 and 2013. These have been tested in experimental and farmers’ fields, and disseminated to farmers in 13 African countries through national agricultural research systems and private seed companies. Yields of the new varieties are superior to those of currently available commercial maize varieties under both stress and optimum growing conditions. Although the benefits of DT maize for African farmers have been repeatedly predicted, realization of those benefits depends on farmer uptake, which has received limited empirical study. We use new plot-level data from surveys of 3,700 farm households in six countries (Ethiopia, Tanzania, Uganda, Malawi, Zambia, and Zimbabwe) to measure DT maize adoption rates and their determinants. The data reveal considerable inter-country variation in farmer uptake of DT maize, from 9 % of maize plots in Zimbabwe to 61% in Malawi. The major barriers to adoption include unavailability of improved seed, inadequate information, lack of resources, high seed price, and perceived attributes of different varieties. Based on the results, we recommend that seed companies and agro-dealers ensure adequate supply of DT maize seed in local markets and sell seed in affordable micro-packs (1 or 2 kg). Furthermore, the DTMA project and partners should ramp up promotional efforts to ensure widespread awareness and understanding of the benefits of the new DT maize varieties.

This paper, published in Crop Science 50: 1-11, presents methodology to prove within a high level of confidence if two samples of seeds are the same genetic population or not, despite the difficulties involved in fingerprinting heterologous populations. In addition to heterogeneity within populations, difficulties can include sampling errors, differences in the fields or years in which the seeds were multiplied, and seed mixing. Despite these confounding sources of variation, the authors show the possibility to conclusively differentiate each of the populations used in this work. This methodology will allow breeders, seed companies, government agencies, and NGOs to ensure the purity and identity of high-yielding, locally adapted OPVs reach farmers, so they can generate the highest yields possible in their fields.

This report gives the results of a study done in 2007. The survey results suggest that a several institutional bottlenecks hamper the smooth functioning of the maize seed sector in Africa.
