Soil Health and Contamination: Processes, Remediation, and Impacts on Food Security

Soil healthHealth is fundamental to sustainable agricultureSustainable agriculture and directly influences food securityFood security, environmental quality, and ecosystem servicesEcosystem services. However, soil contaminationSoil contamination from anthropogenic activities such as industrialization, intensive farming, and improper waste managementWaste management poses significant threats to these critical functions. The complex processes of soil contaminationSoil contamination involve multiple sources, pathways, and impacts on soil healthHealth, affecting microbial activity, nutrientNutrient cycles, and ecosystem functioning. These disturbances can lead to reduced crop yieldsCrop yield, compromised food quality, and long-term public healthPublic health risks, exacerbating global food insecurity. This chapter focuses on the intricate dynamicsDynamics between soil healthHealth and contaminationContamination, highlighting the mechanisms through which contaminants affect agricultural productivity and food securityFood security. It also explores various remediation strategies, including bioremediationBioremediation and phytoremediationPhytoremediation. It emphasizes the importance of integrating innovative technologies like artificial intelligenceArtificial intelligence (AI) and predictive modelingPredictive modeling to enhance the efficiency of these methods. Additionally, the chapter stresses the need for a comprehensive, multidisciplinary approach to soil management that involves farmers, researchers, policymakers, and communities working together to restore contaminated soils and secure the future of global food systems. By examining the socio-economic, environmental, and technological barriersTechnological barriers to effective remediation, particularly in developing regions, this chapter offers insights into how sustainable soil management practices can be applied to ensure environmental justiceEnvironmental justice and long-term agricultural viability.
