Super El Niño Threatens Southern Africa Bean Harvests And How To Protect Farmers

Extreme climate shocks have cut legume harvests by up to 78% in the past and could do so again as a rare super El Niño takes hold between September 2026 and early 2027. Beans serve as the primary staple and second-most significant source of dietary protein across the region, while also representing an essential source of calories and income for rural households and small farmers globally. Agricultural researcher Moses Chitete warned that repeated climate shocks deepen poverty and leave farming families who are already not very well off unable to recover before the next season.

Southern African Bean Harvests Face Severe Risks From Climate Shocks

Grain legumes, commonly called pulses, are sensitive to water stress and high temperatures during critical growth stages including flowering, pod formation, and grain filling. Droughts, floods, extreme heat, and unpredictable rainfall affect legume crops across southern Africa. Moses Chitete noted that these climate shocks reduce agricultural production, leaving households with less food and less produce to sell, which can increase food prices and reduce the availability of affordable sources of protein.

Super El Niño Threatens 2026 and 2027 Agricultural Production

Meteorologists and scientists use the term super El Niño to describe a rare, exceptionally strong El Niño event where forecasts suggest warming of the central Pacific above 3°C. Oluwole Hammond, Programme Officer for Adaptation and Resilience Investment Platforms at the African Climate Foundation, explained that layering this severe weather pattern on an already warming world creates a development challenge rather than just a climate event. The World Meteorological Organisation expects the current cycle to persist from September 2026 into early 2027, potentially triggering severe droughts and high temperatures that threaten legume farmers across southern and eastern Africa, especially the Sahel.

Zimbabwe and SADC Work to Expand Early Warning Systems

Governments across the region are working to expand forecasting capabilities and response protocols ahead of the season. Zimbabwe formally launched its own Early Warnings for All Initiative in August 2026, part of a UN-backed global push. Meanwhile, the Southern African Development Community held a Regional Coordination High-Level Session on Strengthening Early Warning Systems in the region to align forecasting, data-sharing and response protocols among member states. However, research from 2022 highlights critical gaps, noting that existing early warning systems in SADC members overwhelmingly fall under meteorological agencies and focus more on hazard detection and weather forecasting rather than full cycle warning systems.

Private Financing Helps Close Agricultural Adaptation Gap

Closing the agricultural adaptation gap requires financial restructuring to prevent emergency spending from increasing fiscal pressures and reliance on debt. Oluwole Hammond emphasized that adaptation goes beyond a public good that should be financed by a public budget. Investments in adaptation can return fourfold in long-term delivery by mitigating potential losses and generating long-term economic gains, making it essential to unlock private sector financing and diversify funding sources.

Agricultural Strategies and Policy Reforms for Resilient Farms

Farmers can mitigate potential losses by planting early-maturing and drought-tolerant legume varieties, conserving soil moisture, diversifying crops, and harvesting and storing water in line with seasonal climate advice. However, simply labeling crops like cowpeas and pigeon peas as climate-smart because they tolerate dry conditions slightly more than many cereal crops does not guarantee survival without newer technologies, such as affordable access to improved and drought-tolerant seed, irrigation, and reliable weather information. Moses Chitete stressed that farmers need timely access to drought-tolerant crop varieties, appropriate planting advice, and financial risk reduction through access to credit and crop insurance.

Farmers should not wait until drought conditions become severe to find ways of recovering.
