Physical Management Strategies for Enhancing Soil Resilience to Climate Change: Insights From Africa

Abstract

In Africa, where agriculture is the backbone of the economy and sustains livelihoods, the increasing threat of climate change necessitates a shift towards strategies that improve soil resilience. This study explores a range of soil and water conservation techniques, organic amendments and agroforestry, focusing on their application to specific soil types such as Luvisols, Lixisols, Ferralsols, Nitisols, Vertisols, Cambisols and Arenosols, tailored to address Africa's diverse agroecological zones under a changing climate. Furthermore, it elucidates the role of soil physical management in ensuring resilience to climate change, supported by evidence from long-term studies. Our review demonstrates that these physical management strategies are essential for improving soil structure, increasing moisture retention, reducing erosion and enhancing soil organic matter. These improvements contribute to more resilient agricultural systems that maintain productivity despite fluctuating climatic conditions. However, their implementation in Africa faces challenges such as high soil variability, barriers to adoption and resource constraints. Despite these obstacles, significant opportunities exist to build resilience through tailored strategies that align with local soil and climate conditions, supported by innovative policies and the integration of traditional knowledge with scientific research. Therefore, we advocate for an integrated approach that harmonises local expertise, scientific advancements and policy interventions to transform Africa's croplands. By addressing both the biophysical and socio-economic aspects of soil management, this approach can foster resilient, productive and sustainable agricultural systems capable of ensuring food security amidst climate variability.
