Economic, Production, and Poverty Impacts of Investing in Maize Tolerant to Drought in Africa: An Ex-Ante Assessment

Abstract: The potential impacts of investing in drought tolerant maize (DTM) in 13 countries of eastern, southern and western Africa were analyzed through an innovative economic surplus analysis framework, to identify where greatest economic returns and poverty reduction may be achieved. Assuming a potential full replacement of improved varieties with DTM varieties, by 2016 there would be economic gains of US$ 907 million over all countries under conservative yield gains, or US$ 1,535 million under optimistic yield gain… Show more

“…High yielding varieties can improve the food self-sufficiency of smallholders and increase income without needing to cultivate extra land. Droughttolerant varieties have helped to stabilize yields, particularly of cereal crops in rain-fed systems (La Rovere et al 2014). As drought, pest and disease outbreaks, and water salinization become more common with climate change and increasing demands on natural resources, changing crop varieties will continue to be among the first lines of defence for improving productivity and resilience in mixed croplivestock systems.…”

“…A recent assessment of DT maize adoption in Africa, based on the economic surplus method, predicted large positive impacts of increasing average yields and reducing yield variability (La Rovere et al 2014). And by decreasing the vulnerability of farm households to drought-related harvest failure, DT varieties also reduce the need for harmful post-failure coping strategies, such as borrowing, reducing food consumption, sale of household assets, or taking children out of school.…”

“…Since cultural beliefs are place specific, and vary across countries, regions, communities, and social groups, this paper takes, as an example, the specific case of small-scale farmers in Gaza Province, Southern Mozambique. Although, in the last 20 years, several drought events have occurred in the province that have impacted farming activities and led to problems such as famine and malnutrition (Devereux 2007;Rovere et al 2014), the most recent drought (from 2014 to 2016) was more prolonged than farmers could remember having experienced before. Therefore, this particular event provided a unique opportunity to gain a richer knowledge and clearer understanding of the farmers' beliefs about the causes of drought.…”
