The agricultural sector in off-grid communities of South Africa faces significant challenges related to water scarcity and energy supply, necessitating robust risk reduction strategies. A comparative study using panel data estimation techniques to analyse the impact of different agricultural irrigation and power supply solutions on productivity outcomes across multiple years. The analysis revealed that a specific combination of solar-powered drip irrigation systems and modular wind turbines significantly reduced water usage by 20% compared to traditional methods, with no loss in crop yield (n = 150 farms over 3 years). This study provides empirical evidence supporting the adoption of hybrid renewable energy solutions for sustainable agriculture in off-grid communities. Communities should be encouraged to adopt solar-powered drip irrigation systems and modular wind turbines as part of their agricultural infrastructure, provided with subsidies or incentives.
