This comparative study examines renewable energy integration within the agri-food value chains of Zimbabwe and Zambia, analyzing their distinct pathways toward sustainable food security and enhanced agricultural productivity. Through a comprehensive desk review synthesizing peer-reviewed literature, policy documents, and cross-country project reports from 2020-2024, this research investigates innovative approaches, economic viability, policy frameworks, and food security impacts of renewable energy adoption across both nations. The study reveals significant disparities in renewable energy policy maturity between the two countries, with Zambia’s 2020 Renewable Energy Strategy demonstrating more structured implementation compared to Zimbabwe’s continued reliance on hydropower systems. Key findings indicate that solar-powered irrigation systems, biogas-enabled cold storage facilities, and hybrid renewable energy microgrids show substantial potential for reducing post-harvest losses by up to 30% while increasing processing capacities. The research identifies women-led solar irrigation cooperatives in Zambia as particularly effective models for gender-inclusive renewable energy adoption. Both countries face similar challenges including inconsistent funding mechanisms, technical skill gaps, and misaligned land-use policies that hinder large-scale renewable energy deployment. The Southern African Power Pool emerges as a critical regional platform for accelerating cross-border renewable energy integration and knowledge sharing. Cost-benefit analyses demonstrate favourable economic returns for renewable technologies over conventional energy systems in agricultural applications, particularly in remote rural areas. This study contributes to the growing literature on renewable energy-agriculture nexus in sub-Saharan Africa and provides actionable insights for policymakers, development practitioners, and climate finance investors seeking to transform agri-food systems through sustainable energy solutions.
