Scaling Regenerative Ag: 10 Smallholder Farmer Cases

This article presents 10 detailed case studies showcasing how smallholder farmers in various regions are successfully implementing regenerative agriculture practices to enhance productivity, soil health, and resilience. Case Study 1 from Koro, Mali, highlights the Dogon people's 'intermittent shade' technique, an ancient method where crops in lowland tropics are grown under well-managed shade trees, boosting production by up to 40%. This leverages tree canopies to regulate microclimates, reduce evaporation, and improve soil moisture retention during dry periods. Case Study 2 in Befandriana Sud, Madagascar, focuses on the Lojy Be cowpea variety, a drought-resistant, nutritious legume that naturally fixes nitrogen, increasing soil fertility and boosting yields of neighboring crops like maize by enhancing nutrient availability without synthetic fertilizers. In Santa Catarina State, Brazil (Case Study 3), EPAGRI promotes Conservation Agriculture involving zero or minimum tillage, crop diversification, and cover crops or green manures, which has scaled nationally to reduce soil erosion, improve water retention, and cut input costs while maintaining or increasing yields. Case Study 4 from San Martín Jilotepeque, Guatemala, details an integrated development program by World Neighbors and Oxfam, where farmers adopted diverse regenerative techniques like intercropping, agroforestry, and livestock integration, yielding nutritional improvements (diverse diets reducing malnutrition), economic gains (higher incomes from multiple products), and social benefits (community cooperatives). Case Study 5 across Honduras, Guatemala, and Mexico demonstrates companion planting maize with mucuna (velvet beans), a full regenerative system that suppresses weeds, fixes nitrogen, and produces the world's cheapest maize through natural soil building. In Guacamayas, Honduras (Case Study 6), the Cantarranas Program taught micro-terracing on steep slopes, enabling irrigated vegetable farming with contour planting, rock barriers, and organic mulching to prevent erosion and support year-round production. Case Study 7 in Bamenda, Cameroon, covers Tephrosia fallow, where farmers plant this legume to enrich soil organically, slashing fallow periods from years to months and allowing frequent cropping cycles with higher outputs. Finally, Case Study 8 spans twelve African nations combating famine through green manures and ground covers, dramatically restoring soil in drought-prone areas for sustained food security. These cases provide actionable, field-tested methods with quantifiable outcomes like yield increases, cost savings, and ecosystem restoration, proving smallholders' pivotal role in scaling regenerative agriculture globally.
