Abstract: Drought and high temperatures are major threats to sustainable food production and consequently the livelihoods of the majority of Africans who depend on fragile agricultural systems. As a response to these threats, climate-smart agricultural technologies, such as drought-tolerant maize (DTM) varieties, have been developed and promoted on the continent.

It is well-known that the adoption of improved technologies generally impacts positively on the wellbeing of adopters. Nevertheless, the magnitude of the impact of any technology or intervention is always an empirical question. Therefore, this study sought to determine the factors that influence the adoption of DTM and subsequently estimate how yield, commercialization intensity, and farm income are affected by adoption. To establish causation, we relied on observations from 200 farm households in the northern region of Ghana and estimated an instrumental variable regression.

Consistent with findings reported in the literature, we found that DTM adoption is primarily driven by access to seed, extension service, labor availability, and location of farm households. In addition, we found that DTM adoption positively impacts on yield and commercialization intensity. The magnitude of impact is not trivial. For example, the yield of farm households increased by more than 150% (936 kg/ha) following DTM adoption. These results imply that policy-makers and development practitioners must support research and promotion of climate-smart agriculture to improve adoption and welfare indicators, such as yield and commercialization.

Seeing is believing: demo farms accelerate adoption of stress tolerant maize

Over 400 farmers from Manyatta in Embu County were on February 7, 2020, invited to a demonstration farm to witness the performance of various high yielding, early to medium maturing, drought tolerant maize varieties. Such occasions aim to encourage them to adopt varieties whose traits they preferred the most.

They were invited by the Seed Trade Association of Kenya (STAK), with the support of the International Maize and Wheat Improvement Center (CIMMYT) in continuation of the work started under the Drought Tolerant Maize for Africa Seed Scaling (DTMASS) project, which was later succeeded by the Stress Tolerant Maize for Africa (STMA) initiative. In attendance were officials from the Embu County government led by its minister in charge of agriculture, Jamleck Muturi, as well as ten seed firms, some of who use CIMMYT’s germplasm for seed propagation and marketing.

Farmers such as 29-year old Nancy Wawira not only learnt of best agronomic practices, but also identified a high yielding, drought tolerant and early maturing variety she hopes to plant on her farm next season.

For others like 52-year-old John Njiru, a father of four children, a higher-yielding variety with a lot of foliage, which remains green even after the maize cob has dried, is what he came looking for. The green maize foliage is significant income source due to demand from livestock keepers. He also feeds his own livestock with it, making substantial savings on animal feed expenditure.
