“…Collaborative efforts among research organisations in five countries, Kenya, Mozambique, South Africa, Tanzania and Uganda, have developed quite a diverse germplasm base through the Water Efficient Maize for Africa (WEMA) project. The WEMA project is a public-private partnership established to develop drought-tolerant and insect-protected maize by using conventional breeding, marker-assisted breeding and biotechnology, with a goal to make these varieties available royalty-free to smallholder farmers in Sub-Saharan Africa through African seed companies (Oikeh et al 2014;Edge et al 2018). Materials developed are tested in multiple environments that represent drought-stress and nonstress (optimum-moisture) locations to identify high-yielding and adapted varieties for release and cultivation in the respective countries.…”

Drought is a devastating environmental stress in agriculture and hence a common target of plant breeding. A review of breeding progress on drought tolerance shows that, to a certain extent, selection for high yield in stress-free conditions indirectly improves yield in water-limiting conditions. The objectives of this study were to (i) assess the genotype × environment (GE) interaction for grain yield (GY) and other agronomic traits for maize (Zea mays L.) across East African agro-ecologies; and (ii) evaluate agronomic performance and stability in Uganda and Tanzania under optimum and random drought conditions. Data were recorded for major agronomic traits. Genotype main effect plus GE (GGE) biplot analysis was used to assess the stability of varieties within various environments and across environments. Combined analysis of variance across optimum moisture and random drought environments indicated that locations, mean-squares for genotypes and GE were significant for most measured traits. The best hybrids, CKDHH1097 and CKDHH1090, gave GY advantages of 23% and 43%, respectively, over the commercial hybrid varieties under both optimum-moisture and random-drought conditions. Across environments, genotypic variance was less than the GE variance for GY. The hybrids derived from doubled-haploid inbred lines produced higher GY and possessed acceptable agronomic traits compared with the commercial hybrids. Hybrid CKDHH1098 ranked second-best under optimum-moisture and drought-stress environments and was the most stable with broad adaptation to both environments. Use of the best doubled-haploids lines in testcross hybrids make-up, well targeted to the production environments, could boost maize production among farmers in East Africa.

“…Accordingly, farmers tend to embark on several agricultural and technical activities, such as adjustment of fertilizer input, adoption of DTSVs and plant crops that require less water, during drought periods (Mpandeli et al, 2015). Governmental support and the political will to introduce technologies and biotechnology for smallholder farmers is understood to be crucial for the success of interventions aimed at enhancing smallholder farmers" adoption of biotechnology and climate change adaptation practices, for instance (Edge et al, 2018;Zizinga et al, 2017). Generally, smallholder farmers in Africa rely on extension services, usually provided by government.…”

Climate change represents a serious threat to African agriculture, consequently leading to water scarcity and climate variability. These challenges negatively impact agricultural production. Climatesmart Agriculture (CSA) technologies, such as drought-tolerant seed varieties (DTSVs), can provide a solution. However, effective adoption and use of these technologies within smallholder communities is not straight forward. This study investigated the factors determining adoption of CSA technologies by exploring the farmers' characteristics, contextual factors, and considered additional factors extracted from farmers' perceptions of CSA technology-specific attributes. The study was carried out in Limpopo Province, South Africa. Quantitative and qualitative data from farmers' cross-sectional survey (n=196) and focused group discussions (n=5), was subjected to descriptive and inferential statistical analysis. Factor analysis reduced 19 identified CSA technologies specific attributes to 5 factors that were used in the multinomial logistic regression model. Results show a range of drivers and barriers influencing DTSVs adoption. The adoption of DTSVs by sampled smallholder farmers were influenced by training and demonstration; knowledge and benefits related to DTSVs; necessary requirements like receiving tractor services on time, knowledge on better dates of DTSVs and weather information; enabling factors like additional training on DTSVs and information including knowledge about other CSA technologies other than DTSVs, gender, marital status and credit access. These results have policy implications for various stakeholders which reinforce multi-actor approach to climate change adaptation and building of functional institutions, enhancing training of smallholder farmers, improving on access to sufficient demonstrations, climate change information and credit support amongst other support.

“…The hybrids were branded and commercialized as DroughtTEGO ® maize hybrid varieties. Examples of these hybrids include WE1101, WE2101, WE2104, WE2109, WE3101, WE3102, WE3104, WE3105 and WE3106 (Oikeh et al, 2014;Edge et al, 2018). On-farm production output and farmers" testimonies showed significant yield advantages with an average yield of about 4.5 t/ha within three years of commercialization of the varieties when compared with local varieties that yield about 2.8 t/ha (Situma, 2018).…”

Impact of DroughtTEGO ® maize hybrids on agricultural productivity and poverty reduction among small-scale maize farmers were analyzed using 642 households in Kenya. The Water Efficient Maize for Africa (WEMA) project coordinated by the African Agricultural Technology Foundation (AATF) developed the varieties. While on-farm production output and farmers' testimonies indicate significantly high productivity over other varieties, a rigorous assessment of impacts at household level is missing. Direct comparison of maize income, total household income and poverty indices shows significant differences between adopters and non-adopters. However, since the observed estimates can be due to differences in both observable and non-observable characteristics between adopters and non-adopters, we cannot have any causal interpretation. This study, therefore, utilized the counterfactual outcome framework based on propensity score methods (PSM) to control for such differences. The results of PSM showed that adoption of DroughtTEGO ® maize varieties led to significant increase in maize income by 82%, total income by 75%, and reduced the depth of poverty by 46-point margins. The study recommends formulation and implementation of appropriate policies to improve the adoption of DroughtTEGO® hybrid maize varieties across the country.
