Abstract
Drought-induced crop failures have significant impacts on food security in northern Ghana's agricultural sector. A mixed-methods approach combining meteorological data analysis with farmer surveys to assess system performance and impact. Early warning signals were accurate in predicting drought conditions, reducing crop losses by an average of 20% across surveyed regions (\(n=50\) farms). The early warning systems significantly improved farmers' preparedness for drought, enhancing their resilience to climate shocks. Implement continuous system upgrades and integrate with local agriculture extension services to maximise benefits.
