Regenerative farming system for restoring African highland soils and boosting productivity

Overview

This solution addresses chronic soil degradation, food insecurity, and rural poverty in the highlands of Africa's Great Lakes region through an integrated regenerative farming system. The approach combines intercropping legume trees with hybrid sugar Napier grass on restored terraces alongside organic livestock integration, creating a synergistic cycle that rebuilds soil fertility, conserves water, and sequesters carbon.

The system is designed for phased validation and community-led scaling, targeting measurable improvements in soil health, crop yields, livestock productivity, and household income. By restoring degraded landscapes and diversifying farm outputs, the approach supports sustainable food production, climate change mitigation, and improved livelihoods for smallholder farming communities.

Technical specifications

Core integrated practices:

• Terrace restoration to reduce erosion and improve rainwater retention on sloped highland farmland
• Intercropping legume trees with hybrid sugar Napier grass to leverage biological nitrogen fixation and deep root systems for nutrient cycling and soil structure improvement
• Organic livestock integration to enrich soil through manure application and provide diversified income streams
• Carbon sequestration potential through enhanced biomass production and improved soil organic matter
• Phased implementation methodology beginning with site selection, followed by terrace construction, intercrop establishment, livestock management, and indicator-based monitoring

Validation framework:

• Experimental plots and pilot projects with control comparisons against conventional farming
• Data collection on soil health indicators, crop yields, livestock productivity, carbon sequestration metrics, and economic outcomes
• Community engagement and consent protocols embedded throughout the research cycle
• Long-term monitoring and adaptive management to ensure sustainability

Technology readiness level

The proposed approach is at an early-to-mid research and validation stage. The research plan outlines a structured methodology moving from site selection and terrace restoration through intercrop and livestock establishment, data collection, and comparative analysis. Success criteria and scaling pathways are defined but have not yet been executed. The next phase involves pilot implementation, baseline data collection, and controlled comparison with conventional farming systems to validate the integrated approach before broader regional expansion and knowledge dissemination through publications, workshops, and seminars.
