Major rice ecologies in Ghana include rainfed lowlands, upland, and irrigated systems. Rainfed lowlands are distributed across all regions but upland is concentrated in Volta and Western regions. There are 22 irrigation schemes but only 13 are used for rice. Irrigated ecology yields the highest but all face challenges from abiotic and biotic stresses. Primary processing involves drying, threshing, winnowing and storage while secondary processing includes parboiling and milling. Constraints include poor quality paddy, inefficient equipment and lack of infrastructure. Recent technologies focus on improved handling, packaging, branding and linkages between value chain actors.
