The CIMMYT community celebrates the illustrious life and mourns the passing on 11 December of Wilfred M. Mwangi, distinguished Kenyan scholar, statesman and researcher who dedicated his career to improving the food security and livelihoods of farmers in sub-Saharan Africa.
Sub-Saharan African farmers typically apply less than 20 kilograms of fertilizer per hectare of cropland — far less than their peers in any other region of the world. In 2014, partners in the Improved Maize for African Soils (IMAS) project developed 41 Africa-adapted maize varieties that respond better to low amounts of nitrogen fertilizer and are up for release in nine African countries through 24 seed companies.
Frequent germplasm exchange between the Americas, Africa and Asia made maize the crop it is today. At one point in 2005, Brazilian elite breeding material was crossed with local Thai varieties, creating a breeding line that spread throughout Asia and even returned to predominate in southern USA.
For Walter Trevisan, Germplasm Enhancement of Maize (GEM) Steering Committee Chair, the transnational history of maize breeding offers several important lessons for maize breeders today.
Agricultural research is changing. In order to have a greater impact, research must be relevant to a greater variety of farmers in different contexts, while being both applicable and adaptable.
Ways must also be found to solve institutional constraints, which are very often beyond the researchers’ sphere of control. Policies can be changed to allow community seed production, better connections established between maize producers and traders, extension systems strengthened or willing agro-dealers found to commercialize new seeds.
