FAO联合国粮农组织：2025年利用地球观测大数据对作物生产力进行标准化全球评估方法报告（英文版）

This working paper introduces the Crop Potential Productivity Index (CropPI), a global index that integrates Earth Observation Big Data with FAO’s Crop Requirements Database to assess the potential productivity of key staple crops (maize, wheat, and rice). The index combines climate, water availability, and soil parameters into a high-resolution (250m) spatial indicator and includes a penalization strategy for seasonal stressors. CropPI has been tested in 11 African countries and validated ag
