Powering Agriculture: Unlocking Africa's Next Green Revolution

This policy brief by the South African Institute of International Affairs argues that integrating renewable energy—specifically solar mini-grids—with agricultural finance and cooperative reform can unlock a 'green revolution' in Africa. Using Uganda as a case study, the document highlights how low productivity and a lack of post-harvest processing limit economic growth and food security, proposing a trifecta of energy access, financial incentives, and micro-enterprise training to empower smallholder farmers.

• Africa's agricultural sector suffers from low productivity and profitability, with maize yields averaging two tons per hectare annually, which is less than 25% of the yields found in the Americas.
• There is a significant 'value-addition gap' in African agriculture; only $40 per ton of value is added post-harvest, representing one-fifth of the value added in high-income countries. The World Bank identifies thirteen major value chains in sub-Saharan Africa with high electricity value-add that could generate 6GW of demand by 2030.
• In Uganda, more than 60% of maize croplands could be most cost-effectively served by mini-grids. This is critical because over half of these croplands are in districts lacking known milling capacity, and current rural milling often relies on low-quality diesel mills.
• Financial barriers severely limit smallholder productivity; over 60% of maize farmers in Uganda cannot afford any cash inputs for their farms. While the addressable market for agro-processing and irrigation in sub-Saharan Africa is $11 billion, the serviceable market drops to $700 million when adjusted for the farmers' ability to pay.
• Poor post-harvest handling leads to massive losses: approximately 30% of annual maize production in Uganda (about 500,000 tonnes or $4.5 million) is lost. Across sub-Saharan Africa, the World Bank estimates annual post-harvest grain losses at $4 billion, exceeding the total food aid received by the continent over the last decade.
• The document recommends that the AU-EU partnership focus on three specific areas: reforming cooperative structures to aggregate produce and leverage scale, deploying mini-grids in farming communities to enable processing, and providing incentives for micro- and commercial finance alongside rural micro-enterprise training.
