Rice Yield Estimation for Individual Rice Plots: What We Can Do and Observe Under Lockdowns and In-between

13 October 2021

The Rural Development and Food Security (Agriculture) Thematic Group, Sustainable Development and Climate Change Department, ADB; Cambodia Resident Mission, ADB; and the government of Cambodia shared the data collection methodology, results and their potential use, and other insights from the crop survey carried out in 2020 to support the Rice Sector Development Program (SDP) project in Cambodia. The study covered close to 400 households, aimed at mapping rice plots and crop yields for three seasons (early wet, wet, and dry seasons) using geotagging, earth observation and machine learning. The results are presented in color graduation in the rice plot map at https://adb-crop-yield.web.app. The crop yield map and gender disaggregation data can be further used in focus group discussions with project beneficiaries to validate crop yield gaps and gender inequalities.

The study confirms the potential use of remote sensing in data collection for future planning amidst lockdowns and movement restrictions due to the COVID-19 pandemic.
