讲座简介：

Enhancing the spatial understanding of crop production systems enables policymakers and donors to better target agricultural and rural development policies and investments, ultimately improving food security and economic growth while minimizing environmental impacts. The Spatial Production Allocation Model (SPAM) utilizes a cross-entropy approach to integrate multiple spatially explicit data sources, producing high-resolution (5-minute pixel) estimates of the distribution of 46 crops and two production types globally. SPAM results have been widely used both within and beyond IFPRI, including by analysts at CGIAR centers, the World Bank, FAO, and researchers in universities and national agricultural research systems in developing countries. This seminar will introduce the SPAM methodology, highlight current model developments, showcase new features in the 2020 version, and outline future work plans.
