By Tendai Keith Guvamombe Ghana’s agricultural sector, a cornerstone of the national economy that employs approximately 45% of the total workforce and contributes roughly 20% to the Gross Domestic Product, is currently facing an existential threat from climate change (IntechOpen, 2026). Because the sector is overwhelmingly rain-fed—with only about 2% of agricultural land under irrigation—any shift in weather patterns directly translates into production losses (IntechOpen, 2026). Recent data indicates that maize yields in Ghana have already declined by 5% to 25% due to these climatic shifts (IntechOpen, 2026).
