Africa’s reliance on maize is under severe threat from escalating droughts, jeopardizing food security for millions. However, a wave of multi-faceted innovations—from genetically improved drought-tolerant seeds and regenerative farming practices to strategic crop diversification and advanced solar irrigation—is transforming agricultural resilience, offering a beacon of hope for sustainable livelihoods and nutrition across the continent.
For millions across Sub-Saharan Africa, maize is more than just a crop; it is the cornerstone of food security and economic well-being. From Kenya’s beloved ugali to Zambia’s staple, maize permeates daily life, providing essential nutrients and forming a significant part of the diet. Yet, this vital crop faces an existential threat: escalating droughts exacerbated by climate change.
Approximately 40% of Africa’s maize-growing regions contend with occasional drought stress, leading to yield losses of 10–25%. A more critical 25% of the maize crop suffers from frequent droughts, with devastating losses up to half the harvest. This instability leaves around 111 million people across East, Central, and West Africa vulnerable to food insecurity, according to the World Bank. The situation is dire, as evidenced by the Horn of Africa’s six consecutive rainy seasons without rain between 2020 and 2023, one of the most severe droughts on record, according to the UNHCR.
The average maize yield in Africa stands at a mere 2.1 tons per hectare, significantly lower than the global average of 5.9 and the US average of 11.1. To bridge this gap, Africa imports approximately $50 billion worth of food annually, predominantly cereals. Supply chain disruptions, like those seen during the COVID-19 pandemic and global conflicts, have led to extreme price volatility, making essential food items like maize two to three times more expensive per bag, further highlighting the urgent need for local solutions.
Innovative Seeds: The Rise of Drought-Tolerant Maize
One of the most impactful responses to the maize crisis has been the development and dissemination of drought-tolerant maize (DTM) varieties. The Drought-Tolerant Maize for Africa (DTMA) project, launched in 2006 and completed in 2015, spearheaded efforts to mitigate drought and other constraints on maize production across 13 African countries. Spearheaded by CIMMYT and the International Institute for Tropical Agriculture (IITA), in collaboration with national agricultural research systems and private seed companies, the project released 160 DTM varieties between 2007 and 2013.
These new varieties demonstrated superior yields under both stress and optimal growing conditions, offering a crucial lifeline to farmers. An ex-ante assessment by La Rovere et al. (2010) projected that by 2016, the DTMA project could generate a cumulative economic benefit of nearly USD 0.9 billion for farmers and consumers, helping over 4 million people escape poverty and improve the livelihoods of many millions more. The success stemmed from extensive testing in research facilities and on farmers’ fields, and sustainable collaborative mechanisms across Angola, Benin, Ethiopia, Ghana, Kenya, Malawi, Mali, Mozambique, Nigeria, Tanzania, Uganda, Zambia, and Zimbabwe. The initiative aimed to increase maize yields by at least one ton per hectare under moderate drought conditions, representing a 20-30% increase over farmers’ conventional yields.
Beyond the DTMA project, continuous breeding efforts by the International Maize and Wheat Improvement Center (CIMMYT) and CGIAR have led to the release and commercialization of over 150 DTM varieties, benefiting approximately 60 million people across 20 countries. These varieties produce an additional 500 kilograms of grain per hectare on average. Further innovations include maize variants resistant to major diseases and pests like fall armyworm, and nutritionally enhanced varieties with higher levels of vitamin A, providing a comprehensive approach to maize resilience. This focus on improved seed varieties has transformed Africa’s seed production landscape, with certified seed output by local startups increasing from 2,000 metric tons in 2006 to 358,312 metric tons by 2023, according to AGRA (formerly the Alliance for a Green Revolution in Africa).
Climate-Smart Farming: Blending Tradition with Technology
While seed technology addresses intrinsic plant resilience, external factors like soil health and water management are equally critical. In South Africa’s North West Province, small-scale farmers have successfully adopted climate-smart agriculture (CSA) techniques. Their adaptation began as early as 2010, leveraging indigenous knowledge to cope with droughts and protect soil, which later integrated with government policies and specialist advice.
The climate-smart techniques proving effective include:
- Planting drought-tolerant maize seeds: Utilizing the new varieties that thrive even in dry conditions.
- Mulching: Covering soil with organic material to retain moisture.
- Cover cropping: Planting grasses or legumes between main crops to nourish and protect the soil.
- Mixed cropping: Growing multiple crops together to naturally repel pests.
- Zero tillage: Planting seeds directly into a mulched layer without disturbing the soil.
Farmers adopting CSA harvested around 6.2 tonnes of maize per hectare annually, a significant improvement over the 3.9 tonnes from traditional methods. This translated to a 30% increase in earnings, providing crucial economic stability and allowing for reinvestment in their farms. The benefits extend beyond yield and income, enhancing soil health, promoting environmental sustainability by storing carbon and reducing greenhouse gas emissions, and improving overall food security through diversified crops and reduced reliance on chemical inputs.
Diversifying the Plate: Beyond Maize Monoculture
The historical dominance of maize, reinforced by colonial policies, led to the neglect of many indigenous African crops. However, a growing understanding reveals that traditional crops like sorghum and teff are inherently more resilient to climate change and often more nutritious than maize. This realization is driving a shift towards diversifying Africa’s food production, moving away from a reliance on just maize, rice, and wheat, which currently constitute 60% of all calories consumed on the continent.
Initiatives like Kenya’s Food4Education nonprofit exemplify this shift. By serving fortified porridge with a base of maize, sorghum, and millet to 600,000 schoolchildren daily, they enhance nutritional quality and create demand for diverse grains. The Kenyan government further solidified this commitment in May 2025 by including sorghum, millet, pigeon peas, and green grams (mung beans) in the National Grain Reserve, a significant policy change aimed at improving food security and promoting climate-smart agriculture. This ensures greater availability and a sustainable supply chain for these resilient crops, addressing challenges like competition with other industries, such as beer production for sorghum.
Empowering Farmers with Technology and Nature-Based Solutions
Beyond seeds and crop choices, agroecology, or regenerative agriculture, offers another powerful path forward. By mimicking natural systems, agroecology restores degraded lands and boosts productivity while reducing reliance on chemical fertilizers. Planting nitrogen-rich peas alongside other crops, for instance, can naturally fertilize the soil. A project in Malawi that intercropped maize with legumes saw yields increase by up to 38%.
However, adopting agroecology requires time for soil microorganisms to rebuild, potentially leading to lower yields in the initial years. This necessitates government support through financial incentives to encourage farmers during the transition. Given that 65% of Africa’s cultivated land is degraded, and the continent loses an estimated $4 billion worth of soil nutrients each year, investments in such long-term, sustainable practices are critical.
Technological advancements are also playing a pivotal role. The Technologies for African Agricultural Transformation (TAAT) toolkit, launched in 2018 by IITA and the African Development Bank (AfDB) in collaboration with CGIAR, has reached 25 million farmers and increased crop yields by an average of 69%, including a 50% increase for maize. This initiative demonstrates the immense potential of bringing technology and training directly to farmers.
Furthermore, solar-powered irrigation systems are gaining popularity. These systems provide a consistent and reliable water supply, crucial for water-intensive crops like maize, and offer security against unpredictable rainfall patterns. They also enable farmers to cultivate a second, rotational crop, optimizing land use beyond a single rainy season. Organizations like the Renewable Energy and Energy Efficiency Partnership (REEEP) are working with the private sector to expand these solutions, empowering farmers with consistent water access and reducing dependence on erratic rains.
The Path Forward: A Resilient Food System
The future of Africa’s food security hinges on continued investment, collaboration, and a holistic approach. It requires sustained support from governments to provide essential extension services, financial incentives, and strengthened agricultural cooperative societies. Collaborative research between academics and farmers can unlock new ways to boost crop production, building more resilient and sustainable agricultural systems.
Ultimately, the goal is to create a food system defined by resilience – one that can consistently provide nutritious food for its people, regardless of climate shocks or global market volatility. By embracing drought-tolerant seeds, climate-smart farming techniques, crop diversification, agroecology, and innovative technologies like solar irrigation, Africa is not just battling a drought crisis; it is laying the groundwork for a more food-secure and prosperous future.
