The International Food Policy Research Institute-Malawi Strategy Support Program has released a policy note on food security and maize markets in Malawi. Although the note discusses the specific case of Malawi, I believe it has implications for all developing countries where food price volatility and its resultant impacts on food security is a policy issue. Here is the policy note’s short abstract
The price of maize has been more volatile in Malawi than in any other country in the region over the last decade. Measures to address this volatility and related food shortages can have unintended negative effects on the sector, keeping farmers in subsistence agriculture and stagnating commercial growth and agricultural transformation. However, relatively simple measures such as increasing the transparency and predictability of maize market policies and improving information on prices and production can go a long way to promoting greater resilience and investment in Malawi.
