To help farmers monitor the start of the agricultural season, ACMAD has developed an interactive tool that uses observed rainfall data to forecast the start of the season. This cutting-edge tool aims to respond to the needs of agriculture stakeholders in predicting and monitoring the season onset. As part of the implementation of the Global Framework for Climate Services in Africa through the Climate Services and Related Applications programme (ClimSA), the African Centre of Meteorological Applications for Development (ACMAD) in collaboration with NORCAP is organizing a training session on rainfall onset prediction and monitoring.
