Resumen

Descripción

Zambia’s rice sector holds significant potential for agricultural diversification, rural income generation and food security, yet continues to underperform due to persistent structural, technical and institutional constraints. Average yields remain below economic viability, production is largely rainfed, and the uptake of irrigation, improved inputs and mechanization is limited. Despite favourable agro-ecological conditions and growing public investment, rice development efforts remain fragmented and uneven across regions and communities.This publication analyses the interdependence between rice sector development and irrigation, highlighting irrigation as a critical driver of productivity, profitability and climate resilience. Evidence from field surveys and regression analysis shows that controlled irrigation can substantially increase profits, but adoption is primarily constrained by limited awareness, weak technical capacities and risk-averse behaviour rather than infrastructure alone. Education, exposure to climate shocks and targeted capacity-building – particularly for women farmers – emerge as decisive factors shaping irrigation uptake.Beyond production, the study identifies systemic weaknesses across the rice value chain, including inconsistent seed systems, limited post-harvest infrastructure, low product quality and poorly structured markets. The absence of coordinated “seed-to-market” interventions prevents productivity gains from translating into higher incomes and competitiveness.The publication argues for a dual-track approach combining national-level reforms – covering policy alignment, input markets and irrigation strategies – with community-level interventions that strengthen farmer organizations, extension services and local capacity. By aligning rice and water sector development and embedding capacity-building alongside infrastructure investment, the study offers practical pathways to close yield gaps, reduce import dependence and position rice as a viable cash crop for smallholders in Zambia.
