Adaptation in agriculture is essential in responding to climate change, particularly in Africa, where agriculture is the backbone for livelihoods and economies. Systems that are unable to adapt to climate change will face declining productivity and increased risks. The impacts of climate change, including rising temperatures, altered rainfall patterns, increased heat stress, and land degradation, significantly affect agricultural output and food security in Africa.
This shows the need for targeted adaptation strategies across African communities and economies, one of which is Climate-smart agriculture (CSA), an approach that critically addresses environmental challenges and offers solutions such as improved seed varieties, better water use, soil management, and climate-informed practices.
This guide outlines six important CSA practices that investors, policymakers, agribusiness founders, and climate-tech innovators should prioritise in Africa in 2026 and beyond.
Climate-smart Agriculture (CSA) is a comprehensive approach developed to improve food security, support sustainable development, and tackle the challenges of climate change.
According to the World Bank, CSA is built on three key pillars:
In practice, CSA is not a single method but a flexible set of strategies adapted to different environments. These include conservation agriculture, which uses techniques like no-till farming and cover cropping to maintain soil health and reduce erosion; agroforestry, where trees and shrubs are integrated into farming systems to improve soil quality and provide additional income; precision farming, which uses technologies such as sensors and drones to optimize the use of water and fertilizers; the adoption of drought-tolerant crop varieties that can withstand limited rainfall; and improved livestock management practices that reduce emissions and maintain healthier grazing systems.
Africa’s agriculture faces intensifying climate-related pressures that directly threaten food security, especially given the continent’s heavy reliance on rain-fed farming systems. Climate-smart agriculture (CSA) becomes urgent in this context because it not only boosts productivity but also strengthens resilience and reduces environmental impact. Understanding how specific climate threats affect food security helps clarify why CSA is critical now.
Erratic Rainfall
Unpredictable rainfall patterns disrupt traditional farming calendars, making it difficult for farmers to determine the right time to plant or harvest. When rains come too early, too late, or stop abruptly, crops may fail to germinate or mature properly. This leads to lower yields and, in many cases, total crop loss. As a result, households experience reduced food availability and unstable incomes, which limit their ability to purchase food. Over time, this unpredictability contributes to price volatility in local markets, making food less accessible for vulnerable populations.
Droughts
Prolonged periods of little or no rainfall severely reduce soil moisture, making it nearly impossible for crops to grow. Droughts also diminish water availability for livestock, leading to poor animal health, reduced milk and meat production, and in extreme cases, livestock death. For farming households, this means both crop failure and loss of livelihood assets, intensifying food shortages. At a larger scale, repeated droughts can deplete national food reserves and increase dependence on food imports or aid, further straining food systems.
Heat Stress
Rising temperatures affect both crops and livestock in multiple ways. For crops, excessive heat can reduce photosynthesis, accelerate evaporation, and shorten growing cycles, ultimately lowering yields and nutritional quality. For livestock, heat stress can reduce feed intake, slow growth rates, and decrease reproduction and milk production. These combined effects reduce the overall supply of food while also affecting its quality, thereby worsening food insecurity and malnutrition.
Climate-Smart Agriculture addresses these challenges by promoting practices that stabilise production under uncertain conditions. By improving water management, introducing drought-resistant crops, and using climate-informed farming techniques, CSA helps ensure more consistent food production. At the same time, it strengthens farmers’ capacity to adapt to changing conditions and reduces harmful emissions, contributing to long-term sustainability.
Research across West Africa links Climate-smart agriculture adoption with higher crop yields and better food security outcomes, with combinations of techniques demonstrating the greatest benefits.
According to Agnes Kalibata, former Rwanda Agriculture Minister and UN Food Systems lead, African farmers are increasingly adopting quick-maturing, pest-resistant varieties to cope with unreliable rainfall.
1. Climate-Resilient and Drought-Tolerant Crops: Climate-resilient crops are plant varieties developed to withstand climate-related stresses such as heatwaves, floods, salinity, pests, and erratic rainfall while maintaining stable yields. Unlike conventional crops that perform best under ideal conditions, climate-resilient crops are designed to remain productive under environmental stress. Their traits include heat-resistant photosynthesis, efficient nutrient use, pest resistance, and adaptability to poor or degraded soils. These characteristics reduce vulnerability to climate shocks and limit dependence on chemical inputs, making them essential for sustainable food systems in climate-exposed regions.
Drought-tolerant crops, on the other hand, specifically address crops that survive and produce yields with limited rainfall. Crops such as sorghum, millet, cowpeas, and improved varieties developed by research institutions and CGIAR centres have deeper root systems and improved water-use efficiency, allowing them to thrive in arid and semi-arid zones. Many of these improved varieties mature within 2–3 months rather than the traditional six months, reducing exposure to prolonged dry periods.
Agnes Kalibata had previously mentioned that African farmers are increasingly adopting quick-maturing, pest-resistant varieties to cope with unreliable rainfall. NERICA, for example, are improved rice varieties developed by crossing African rice landraces with Asian rice lines, making them well-suited to diverse growing conditions across Africa. These cultivars enhance resilience to weather variability, deliver higher yields, and strengthen food security, positioning them as a key component of climate-smart agriculture.
2. Practice Conservation Agriculture: Conservation agriculture involves practices such as minimal soil disturbance, cover cropping, and crop rotation, which help preserve soil structure, retain moisture, and reduce erosion. Complementary techniques, including terracing, contour farming, mulching, rainwater harvesting, and drip irrigation, further aid soil health and water efficiency.
Mulching with crop residues can significantly reduce evaporation losses; similarly, drip irrigation delivers water directly to plant roots, saving substantial water. Together, these methods improve resilience to climate variability and support more sustainable crop production.
In practice, farmers can begin by mapping land slopes to construct terraces, collecting post-harvest crop residues for mulching, and installing low-cost drip irrigation kits, which often pay for themselves within 1–2 years through higher yields. Rainwater can also be harvested from rooftops or small ponds for supplementary irrigation.
3. Agroforestry Integration: Agroforestry integrates trees with crops and livestock to improve shade, soil stability, erosion control, and soil fertility through leaf litter and nitrogen fixation. Trees also function as carbon sinks, supporting emissions reduction while enhancing farm resilience. In Mali, Rokiatou Traoré’s Herou Alliance planted over 2,000 Moringa trees to restore degraded land while creating sustainable value chains that economically empowered women.
Farmers can select nitrogen-fixing and multipurpose trees such as acacia or the indigenous locust bean tree (Parkia biglobosa), integrate them along farm borders or in alleys, prune branches for fodder or mulch, and harvest fruits seasonally.
In Nigeria, ginger farmer Bala Musa observed that ginger grown under the shade of locust bean trees survived a widespread ginger blight that destroyed neighbouring unshaded farms, highlighting how indigenous trees can buffer crops against climate-related stress and disease outbreaks. The trees improved microclimatic conditions, reduced heat stress, and enhanced soil health, turning traditional knowledge into an effective climate adaptation strategy.
4. Crop Diversification: Crop diversification involves rotating and intercropping cereals and legumes to improve soil fertility, break pest cycles, and spread climate risk. Legumes fix atmospheric nitrogen, while diversified systems ensure that if one crop fails due to weather or pests, others can still perform.
Across West Africa, diversified cropping systems and other climate-smart practices emphasised under the Comprehensive Africa Agriculture Development Programme (CAADP) have been shown to increase agricultural productivity, strengthen resilience to climate variability, and support emissions reductions by integrating diversified landscapes and adaptive farming methods into national planning and investment strategies.
Implementation begins with soil testing to guide crop rotation (e.g., maize–legume systems), intercropping for ecological, and marketing diversified produce through cooperatives.
5. Integrated Pest Management (IPM): Integrated Pest Management combines biological control, resistant crop varieties, and cultural practices to manage climate-driven pest outbreaks while reducing reliance on chemical pesticides. Techniques include promoting natural predators, intercropping to disrupt pest life cycles, and planting resistant seeds. Farmers can apply IPM by scouting fields weekly, planting trap crops, releasing beneficial insects, and rotating crops to break pest cycles.
6. Improved Soil Fertility Management: Improved soil fertility focuses on composting, green manures, and balanced fertiliser application based on soil testing to enhance soil structure, nutrient availability, and water retention. Compost returns organic matter to the soil, while green manures replenish nutrients before planting. Farmers can compost agricultural waste using a 3:1 carbon-to-nitrogen ratio, grow and plough in green manures, and apply fertilisers precisely based on test results.
Cornelius K. A. Pienaah, a climate and food systems expert, explains that effective adaptation in African agriculture must be community-led, long-term, and rooted in farmers’ lived realities. He emphasises that climate-smart agriculture delivers results only when scientific evidence is combined with local knowledge through demonstration plots, farmer field schools, and collective action platforms such as village savings groups.
Pienaah cautions that short funding cycles and fragmented policies weaken adaptation outcomes, noting that practices like conservation agriculture require sustained investment over several years to achieve yield stability and resilience. Without reliable water infrastructure, consistent extension services, and policy continuity, he argues, farmers are pushed beyond their coping capacity, making CSA not merely a productivity intervention but a necessary social and economic adaptation strategy for climate-vulnerable food systems.
Climate-smart agriculture is not only a conceptual framework for Africa, but it is an operational necessity for sustaining food systems under accelerating climate stress. Rising temperatures, water scarcity, soil degradation, and pest pressures are already reshaping agricultural outcomes across the continent, making adaptation central to productivity, resilience, and economic stability.
For policymakers, investors, and development partners, the priority in 2026 must be scaling integrated CSA systems rather than isolated interventions, aligning long-term financing, extension services, and market access with on-farm adaptation. When climate-smart agriculture is treated as a core development and investment strategy, it protects livelihoods, strengthens food security, and builds resilient African economies in a warming world.
