Food Security in Southern Africa: A Growing Challenge Amidst Climate Change

Food security remains one of the most pressing challenges in Southern Africa. With climate change, economic instability, and growing population pressures, millions of people in the region face the risk of hunger and malnutrition. Southern Africa is particularly vulnerable to climate-induced shocks, such as prolonged droughts, floods, and irregular rainfall patterns, which affect agricultural productivity—the backbone of many economies in the region.

According to a 2023 report from the Food and Agriculture Organization (FAO), approximately 45 million people in Southern Africa are experiencing acute food insecurity. Countries like Zimbabwe, Mozambique, Malawi, and Zambia are witnessing rising levels of hunger due to climatic extremes, with droughts and floods becoming more frequent. The region's food security is increasingly fragile, especially in rural areas where agriculture is predominantly rain-fed, and farmers are ill-equipped to handle the rapid changes in weather patterns.

The Impact of Climate Change on Food Security

Climate change exacerbates the natural vulnerabilities of Southern Africa, where smallholder farmers dominate the agricultural sector. According to the World Bank, around 70% of the region’s population depends on subsistence farming for their livelihoods. These farmers are highly susceptible to climatic variability because they often lack access to irrigation, resilient seeds, and the resources necessary to adopt climate-smart agricultural practices.

A recent assessment by the Southern African Development Community (SADC) revealed that smallholder farmers are among the hardest hit by erratic weather patterns. In the 2023 SADC Food Security Early Warning System report, the findings show that rural communities that depend on farming as their primary food source are becoming more food insecure, primarily due to extended dry spells, late rains, and irregular rainfall distribution.

Dr. Wellington Manyiwa, a climate scientist from the University of Zimbabwe, notes that “the region is witnessing the direct consequences of global warming. The frequency and intensity of droughts, especially in countries like Zimbabwe and Zambia, have increased, leading to crop failure and food shortages.”

Food Insecurity Data in 2023

The Integrated Food Security Phase Classification (IPC), a multi-partner initiative for classifying the severity of food insecurity, highlights alarming statistics for the region:

• In Zimbabwe, over 7.9 million people—more than half of the population—are expected to face acute food insecurity by the end of 2024. This situation is worsened by consecutive years of drought and the country's fragile economic situation.
• In Mozambique, more than 1.9 million people are food insecure, largely due to recurrent flooding and cyclones such as Cyclone Idai in 2019 and Cyclone Freddy in 2023, which destroyed vast agricultural areas.
• Malawi, often referred to as the “warm heart of Africa,” faces an increasing food security crisis with 5.4 million people estimated to be in a state of food insecurity. The country’s heavy reliance on maize as the staple crop means that any disruption to maize production can have catastrophic effects.
• In Lesotho, around 338,000 people (22% of the population) face food insecurity due to drought and poor rainfall distribution during the main planting season.

The World Food Programme (WFP), in its 2023 report, described the food situation in Southern Africa as "precarious," noting that "climate extremes, poverty, and a lack of access to agricultural inputs have left many rural households unable to grow enough food to sustain themselves."

Smallholder Farmers: At the Frontlines of Climate Change

Smallholder farmers—those farming less than two hectares of land—play a crucial role in Southern Africa’s food systems. These farmers produce the majority of the food consumed in rural areas, but they also face the greatest risks from climate change. For instance, smallholder maize farmers in Malawi are struggling to adapt to changing rainfall patterns, which have shifted planting seasons and increased the risk of crop failure.

A farmer in Malawi’s central district, John Kamanga, shared his experience: “In the past, we could predict the rains and plan our planting. Now, the rains are either too little or too much, and the planting seasons keep changing. Many of us have lost crops to drought and floods.”

Climate change has also affected the availability of water for irrigation. Southern Africa, particularly countries like Zimbabwe, Botswana, and Namibia, have long faced water scarcity, and changing climate patterns are making water even scarcer. Irrigation systems are not widespread in the region, making most agriculture heavily reliant on rainfall.

Professor Margaret Dube, an agricultural economist from the University of Botswana, highlights how smallholder farmers are disproportionately affected by these challenges: “Smallholders don’t have the financial buffer to absorb crop losses. When a drought or flood occurs, they often lose everything and can’t afford to buy inputs for the next planting season. Many resort to selling livestock or other assets to survive, leading to a downward spiral of poverty and food insecurity.”

The Role of Government and International Agencies

Governments in Southern Africa have recognized the need to support smallholder farmers in adapting to climate change, but the scale of the challenge often exceeds the resources available. Many countries have adopted national strategies that promote climate-smart agriculture (CSA) practices, which are designed to increase productivity, enhance resilience, and reduce emissions.

For instance, the Government of Zambia has introduced the Zambia Integrated Forest Landscape Program (ZIFLP), which promotes sustainable land use practices and improved water management to enhance agricultural resilience in the face of climate change. Zambia’s Minister of Agriculture, Ruben Phiri, acknowledged the importance of such initiatives during a regional climate summit in 2023: “Our farmers need to be empowered with the knowledge and tools to practice agriculture that can withstand climate shocks. Without significant intervention, food security will remain elusive.”

Similarly, the Zimbabwean government has partnered with the FAO to promote the use of drought-tolerant crops like sorghum and millet as alternatives to maize, which is highly susceptible to drought. However, the uptake of these crops remains slow due to cultural preferences and market dynamics that favor maize.

International agencies such as the World Food Programme (WFP), United Nations Development Programme (UNDP), and the International Fund for Agricultural Development (IFAD) are also playing a key role in promoting resilience-building activities in Southern Africa. The WFP, in collaboration with SADC, has initiated programs aimed at strengthening food systems, providing climate risk insurance to farmers, and improving agricultural infrastructure.

In Mozambique, the WFP has launched an innovative project where smallholder farmers receive weather-indexed insurance. This insurance provides compensation in case of extreme weather events like drought, allowing farmers to recover and replant. Eliseu Nhantumbo, a smallholder farmer from Mozambique’s Sofala province, mentioned: “Before the insurance, if there was a drought, I had no way to recover. Now, I have some hope that I can continue farming even if the weather is bad.”

Regional Cooperation: The Role of SADC

The Southern African Development Community (SADC) plays an essential role in promoting food security across the region. Through its Regional Agricultural Policy (RAP), SADC aims to ensure long-term agricultural productivity and enhance the resilience of agricultural systems to climate change. The policy includes initiatives to improve infrastructure, promote agricultural research, and foster intra-regional trade to offset localized food shortages.

SADC's Disaster Preparedness Program, launched in 2021, focuses on early warning systems and strengthening disaster risk management in member states. By providing timely data on weather patterns, the program aims to help farmers better prepare for droughts, floods, and other climatic shocks.

However, SADC's role has been constrained by the financial limitations of member states and the scale of the challenge. Dr. Ncube Mathebula, a food security expert based in South Africa, observes: “SADC has made significant progress in coordinating regional efforts to address food insecurity, but the issue is that climate change is a transboundary problem. No single country or regional body can solve it without substantial international support and funding.”

Climate-Smart Solutions for Future Food Security

For Southern Africa to achieve food security in a changing climate, the adoption of climate-smart agricultural practices is critical. These include practices such as conservation agriculture, crop diversification, integrated pest management, and agroforestry. These strategies aim to boost agricultural productivity while ensuring environmental sustainability.

Conservation agriculture, for instance, involves minimal soil disturbance, crop rotation, and soil cover. It has been shown to improve soil health and water retention, which is essential for areas that suffer from drought. In Zambia, smallholder farmers who adopted conservation agriculture increased their yields by up to 50% despite erratic rainfall, according to a 2022 report from the International Institute for Environment and Development (IIED).

Crop diversification, particularly the promotion of drought-tolerant crops like sorghum, millet, and cassava, is another promising solution. These crops require less water and are more resilient to drought compared to maize. Additionally, agroforestry—where trees are integrated into farming systems—can improve soil fertility and provide shade for crops, reducing water loss.

Dr. Blessings Chitopota, a researcher at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), underscores the importance of these practices: “Climate-smart agriculture is the future of food security in Southern Africa. If smallholder farmers are to thrive in this new climate reality, they need access to improved seeds, training, and financial support.”

Food security in Southern Africa is under significant threat from climate change, population growth, and socio-economic challenges. Smallholder farmers, who are the backbone of food production in the region, are disproportionately affected by these changes, and without adequate support, the
