Soil Systems and Agricultural Productivity for Food Security in the Global South

As the population continues to grow in sub-Saharan Africa and other countries in the Global South (GS), ensuring sustainable food production becomes increasingly vital. This chapter explores the challenges faced by farmers and other land users in GS, including soil degradation, erosion, contamination, deforestation, and land use conflicts, which negatively impact soil health and productivity. These challenges are compounded by the effects of climate change, further exacerbating food insecurity. To address these complex issues, a comprehensive approach based on sustainable soil management practices is recommended. This includes the adoption of conservation agriculture, integrated soil fertility management (ISFM), agroforestry, and efficient water management techniques, which have been identified as potential solutions. These approaches can help mitigate soil degradation, maintain soil fertility, and enhance overall ecosystem resilience. In addition to implementing sustainable soil management practices, empowering farmers with access to soil testing facilities, knowledge-sharing programs, and extension services is crucial. By providing farmers with the necessary resources and information, they can make informed decisions and implement sustainable practices on their land. Policymakers also play a significant role in addressing these challenges. Implementing supportive policies that incentivize sustainable agricultural practices and protect natural resources is essential. Policymakers can contribute by promoting climate-smart agriculture, supporting research and innovation, and establishing regulations that ensure the responsible use of resources. Adoption of climate-smart agriculture and embracing innovative techniques, countries in the Global South can enhance soil health, increase agricultural productivity, and achieve food security for present and future generations. This chapter serves as a guide for researchers, policymakers, and practitioners seeking to address the urgent sustainable food production challenges in the Global South.
