This report focuses on presenting detailed account of the implementation of the approach, the lessons learned, analyzing whether there is enough experience to suggest (or not) extrapolation of the approach to other areas and communities, and the way forward. The report is based on data and information generated from participating farmers and key individuals from important institutional stakeholders.

This report presents the synthesis of household level surveys in five intervention countries (Angola, Malawi, Mozambique, Zambia, and Zimbabwe) of the Drought Tolerant Maize for Africa (DTMA) project designed and implemented by the International Maize and Wheat Improvement Center (CIMMYT), International Institute for Tropical Agriculture (IITA) and national research and extension institutions in 13 countries of Sub-Saharan Africa (SSA). In each of the study countries, two districts were randomly selected provided that the districts fall in predetermined categories (20-40%) of probability of failed season (PFS). A total sample of 1108 households was randomly drawn with sample sizes varying country to country. The report has different sections that focus, in order, on description of the sample households, extent and determinants of poverty and inequality among the sample population, characteristics of maize production, perception and management of drought risk, and determinants of likelihood and intensity of adoption of improved maize varieties.

In 2006, the Drought Tolerant Maize for Africa (DTMA) project was initiated withthe aim of improving maize germplasm in the drought prone mid-altitude regions ofeastern and southern Africa (ESA). Through this project eight hybrids and four openpollinatedvarieties (OPVs) were developed through multi-location trials under optimal(well fertilized and well-watered conditions), rainfed, low soil nitrogen and manageddrought stress environments. To validate the performance of the new germplasm againstcommercially available germplasm and farmer-preferred varieties, a series of trials wereconducted across 49 farmers’ fields in eight countries in 2010/11 seasons in ESA. Trialswere un-replicated and conducted under farmer management, with farms consideredblocks in a randomized complete-block design. Average trial yields ranged from 0.7 t ha-1 to above 8 t ha-1. Trials were divided into two categories based on yield levels; high yieldingtrials >=3 t ha-1 (n = 30 trials) and low yielding trials < 3 t ha-1 (n = 19 trials). Broad senseheritability of high and low yielding trials was 0.80 and 0.62 to 0.94 and 0.61, respectively,indicating that highly repeatable means can be estimated from un-replicated on-farmtrials in ESA. The best new DTMA hybrids out-yielded the farmers’ own varieties by morethan 35% and 50% under low- and high-yield conditions, respectively, when compared to SC513, the most widely grown commercially hybrid available varieties in southern Africa.

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.
