Machine Learning Forecasts Rice Yields in Sierra Leone with Climate Data

A new study published on arXiv explores the potential of machine learning to forecast rice yields in data-constrained environments, specifically focusing on Sierra Leone. Researchers found that models trained solely on crop statistics performed no better than simple persistence. However, when augmented with free satellite climate data, machine learning models, particularly XGBoost, significantly reduced forecast error by one-third, highlighting early-season rainfall as a key predictor. The study also noted that institutional factors, not climate, were responsible for a past yield collapse, and offers policy recommendations based on these findings. AI
