A coalition of agricultural organizations, including Solidaridad, Kvuno, the International Institute of Tropical Agriculture (IITA), and the Soybean Innovation Lab, is implementing an Early Warning System (EWS) to safeguard smallholder farmers in Southern Africa from soybean rust, a fungal disease exacerbated by climate change. This system, established in Malawi, Zambia, and Mozambique, uses sentinel plots to identify the disease and alerts farmers via mobile phone to enable timely fungicide applications and crop protection. This initiative aims to enhance smallholder farmers' resilience to the challenges posed by climate change and ensure food security through sustainable agricultural practices.
