Extension education strategy for minimizing aflatoxin impact on sub-Saharan African agriculture and food systems

摘要

Sub-Saharan Africa (SSA) is the most vulnerable region of the world to all aflatoxin-related problems including food insecurity, ill health and reduced foreign exchange earnings. Aflatoxin-contaminated maize, groundnuts (peanuts), sorghum and other crops reduce human access to adequate calories from these staples; consumption of aflatoxin-contaminated foods results in severe health conditions, including liver cancer, that deny the region a significant amount of otherwise productive man-hours; while the reduction of grain quality below the international standards due to aflatoxin contamination drastically reduces income in foreign exchange earnings. Scientific knowledge of the causes of aflatoxins in agricultural systems and their mitigation abounds in research institutions in SSA and internationally, but most of this knowledge is unavailable to farmers, food consumers and policy makers in useful form due to poor extension education and ineffective extension services. A paradigm shift in the approach to extension in SSA is proposed, one driven by a sustainable mechanism that is sensitive to the needs of the people and proactive (rather than reactive) in providing solutions to aflatoxin-related problems the local community and policy makers have to deal with. This paper argues that such sustainable mechanism may only be found in a University-based and University-run 'land grant' type extension services adapted appropriately to SSA conditions.
