Policy and competitiveness of agroforestry‐based technologies for maize production in Cameroon: An application of policy analysis matrix
运用政策分析矩阵评估喀麦隆高地稀树草原地区农林复合技术下玉米生产的社会盈利性，并分析政策变化对财务竞争力的影响，发现农林复合系统具有高比较优势。
Abstract Questions have been raised about the ecological consequences and economic sustainability of exclusive reliance on chemical fertilizers for the rapidly expanding maize production across sub‐Saharan Africa. Alternative agroforestry‐based natural resource management technologies have been developed for farmers. This paper applies the policy analysis matrix (PAM) to analyze the social profitability of agroforestry‐based technologies for maize production in the highland savanna zone of Cameroon, and the impacts of policy shifts on the financial competitiveness of maize production under these technologies. The paper shows that maize production under agroforestry‐based systems has high comparative advantage.
