Exploring strategic priorities for regional agricultural R&D investments in East and Central Africa
利用高分辨率空间数据评估东非和中非11国15种主要作物的技术溢出效益，识别出能带来最大福利收益的作物、国家和农业气候区域，为区域农业研发投资优先序提供依据。
Abstract The 11 countries of East and Central Africa have diverse but overlapping agroclimatic conditions, and could potentially benefit from spillovers of agricultural technology across country borders. This article uses high‐resolution spatial data on actual and potential yields for 15 major products across 12 development domains to estimate the total benefits available from the spread of new agricultural technologies around the region. Market responses and welfare gains are estimated using the Dynamic Research Evaluation for Management model, taking account of current and future projections of local and international demand. Results suggest which crops, countries, and agroclimatic regions offer the largest total benefits. Downloadable data and program files permit different assumptions and additional information to be considered in the ongoing process of strategic priority setting.
