Drought Resilience Strategies in Smallholder Agriculture

Smallholder farmers in marginal environments increasingly confront erratic rainfall and prolonged dry spells that threaten crop productivity and food security. A multifaceted array of resilience strategies has emerged, combining advances in plant breeding, agronomic innovation and enabling socio-institutional measures. Genetic approaches focus on drought-tolerant and early-maturing crop varieties that maintain yield under water deficit or escape terminal drought. Soil and water management practices – including rainwater harvesting, mulching, conservation tillage and agroforestry – enhance soil moisture retention and reduce erosion. Digital tools and improved weather forecasting support timely decision-making on planting and input use, while extension services, credit access and robust seed systems are pivotal in scaling up adoption. Integrated interventions that tailor variety choice, management techniques and capacity building to local agro-ecological and socio-economic contexts have demonstrated the greatest promise. By aligning technological, ecological and institutional components, smallholder systems can bolster productivity, stabilise incomes and contribute to broader rural resilience in the face of a changing climate.

Research from Nature Portfolio

A comprehensive review of climate-resilient crop adoption synthesised three decades of evidence from low- and middle-income nations. Drought tolerance emerged as the most prevalent trait, with water-use efficiency also critical. Adoption determinants included the availability and efficacy of extension services, farmers’ education levels, reliable access to seeds and fertilisers, and household socio-economic status. Social factors such as gender and ethnic differences further influenced uptake. The analysis proposed integrated pathways – encompassing outreach, input supply, and capacity building – to enhance adoption rates and reduce dis-adoption of climate-resilient crops.
