Climate is an important factor in agriculture, it is considered the driving force of the agricultural sector due to its strong influence. An essential factor in economic growth, agriculture represented 4% of global gross domestic product according to the United Nations (UN). A greater contribution in developing countries representing 25% of national GDP. The agricultural sector is today responsible for feeding 8 billion people on earth. It was recently estimated that more than 866 million people around the world work in agriculture. A figure which represents 10.8% of the world population[1]. If in recent years climate change has been at the center of discussions, we must emphasize the impact of climate change on vulnerable countries in West Africa which is even more significant and which infects their agri-food systems.
In recent years, climate change and its consequences have been felt on the agro-food system of West African countries, which are already vulnerable. A vulnerability which is defined by famine, low agricultural yield, poverty, soil degradation, scarcity of vital resources, (FAO, Luanda, Angola, 3 – 7 may 2010). Note that West Africa today represents nearly 37% of the population of the subcontinent and is expected to increase from 400 million inhabitants to 700 million inhabitants by 2050 according to statistics. Faced with such demographic growth and with a view to preventing the worst from happening, the urgency of finding alternatives to counter the climate issue is felt.
The Reall question here is: How can innovations and policies in the agri-food system effectively mitigate the impacts of climate change on the vulnerabilities of West African populations; specifically in terms of famine, health, agriculture, poverty, drought, and floods?
Challenges Facing the Sahel and West Africa
The Sahel region, encompassing Burkina Faso, Mali, and Niger, faces profound challenges related to its geography and climate. The area’s reliance on rainfed agriculture, limited irrigation systems, and landlocked status compounds its vulnerability to food insecurity, migration, and displacement. Climate change further exacerbates these issues, reducing agricultural yields and heightening the vulnerability of populations who depend on farming for their livelihoods. The ongoing instability caused by terrorist attacks in the region deepens this crisis, leading to the displacement of communities, loss of livelihoods, and worsening food insecurity.
The broader West African region shares many of these challenges, particularly with the degradation of ecosystems and biodiversity. The overexploitation of wildlife, deforestation, and unsustainable agricultural practices contribute to habitat loss, pollution, and a decline in biodiversity. This environmental degradation has direct consequences for food security and the livelihoods of rural populations, many of whom rely on natural ecosystems for subsistence. In addition, poor land distribution and the impact of extractive industries, such as mining, contribute to the deterioration of West Africa’s environment and further threaten food security. Global factors like famine, conflict, natural disasters, and the COVID-19 pandemic have worsened the situation in West Africa. Hunger has increased globally, disproportionately affecting developing countries. Key drivers include demographic growth, agricultural disruptions, and economic challenges, all of which have led to a sharp rise in food insecurity since 2019. In West Africa, this crisis is compounded by poor infrastructure, limited healthcare access, and dependence on food imports.
Climate Change and Food Insecurity in West Africa
West African agriculture is particularly vulnerable to the impacts of climate change. Rising temperatures, erratic rainfall patterns, resource scarcity, and the increased frequency of extreme weather events are already affecting agricultural productivity across the region. These factors, combined with the loss of biodiversity, further intensify food insecurity, poverty, and the vulnerability of rural economies that depend heavily on farming.
As climate change continues to worsen, millions of people in West Africa who depend on agriculture for their livelihoods are at risk. The consequences of this are multifaceted. Food insecurity will rise as crops fail or yields diminish, leading to higher levels of poverty and displacement. Furthermore, the degradation of ecosystems will result in a loss of biodiversity, which has implications for both food security and the environment.
However, there are opportunities to address these challenges by leveraging West Africa’s traditional knowledge, diverse ecosystems, and emerging technologies. Climate-smart agricultural practices offer a promising solution. These practices enhance agricultural productivity and resilience while mitigating the environmental impacts of farming. For example, agroforestry and conservation agriculture can improve soil health, boost biodiversity, and help retain moisture, reducing the risk of erosion and land degradation. Additionally, developing climate-resilient crop and livestock varieties tailored to local conditions can help secure agricultural productivity despite the impacts of climate change.
Solutions for Building a Resilient Future
Addressing the environmental and agricultural challenges in West Africa requires a comprehensive approach that integrates scientific research, traditional wisdom, technological innovation, and policy reform. A major focus should be on adopting climate-smart techniques like agroforestry, which enhances soil health and biodiversity while providing income for farmers. Conservation methods such as minimal tillage and crop rotation help retain soil moisture and prevent erosion, key factors in sustaining agricultural productivity in a changing climate.
Investments in research and development are essential to promote the use of climate-resilient crops and livestock that are better suited to withstand the region’s environmental conditions. Diversifying agricultural production is also crucial to reduce risks associated with monocultures and enhance food security. This approach, combined with efforts to build sustainable agricultural systems, offers hope for long-term resilience in the face of climate change.
Policy reform is central to these efforts. Governments, international organizations, and private sector partners must collaborate to support smallholder farmers, improve climate information services, and ensure equitable development in rural areas. Strengthening infrastructure—such as irrigation, transportation, and storage systems—will further improve the resilience of agricultural value chains. Additionally, expanding access to finance, insurance, and social safety nets will be critical in helping farmers withstand the financial and environmental shocks brought on by climate change.
Conclusion
The Sahel and West Africa face profound challenges due to the combined impacts of climate change, environmental degradation, and economic instability. Yet, there are also opportunities for positive change. By leveraging traditional knowledge, investing in climate-smart agricultural practices, and enacting policy reforms, the region can build a more resilient and sustainable agricultural system. Ensuring food security, promoting economic growth, and protecting the environment for future generations will require a holistic approach, combining research, innovation, and collaboration across sectors. The path forward is challenging, but with coordinated efforts, West Africa has the potential to overcome these obstacles and achieve sustainable development.
