Utilization of high-resolution satellite images to improve statistics for the sweetpotato cultivated area of Kumi district, Uganda

Natural Resources Management Division, Working Paper No 2007-5.

This working paper has been written by scientists from different research divisions of the International Potato Center (CIP). It describes a methodology based on the use of high-resolution satellite images and spectrordiometry to gather data to construct reliable statistics on sweetpotato cropping areas. The pilot study was conducted in a region located in eastern Uganda, where sweetpotato is cultivated in two cropping seasons. The results suggest that the tested method substantially improves estimation of cropping areas compared to traditional statistics based on field surveys and censuses.
