Salinization

Salinization refers to the accumulation or buildup of soluble salts in soil or water, which can be significantly worsened by factors associated with climate change, such as sea-level rise. When saltwater intrudes into freshwater or soil due to rising sea levels or excessive irrigation with saline water, salts concentrate in the soil’s root zone, making it difficult for plants to absorb water effectively. This threatens agriculture by reducing crop yields, harming plant growth, and degrading soil health. Additionally, salinization contaminates drinking water supplies, posing risks to human health. The increasing soil salinity affects microbial communities and nutrient cycles, leading to broader ecosystem consequences. Coastal and arid agricultural areas are particularly vulnerable. Climate change-related shifts—such as changing precipitation patterns, higher temperatures causing greater evaporation, and extreme weather events—further exacerbate salinization. Addressing salinization requires integrated management practices including improved irrigation techniques, soil conservation, restoration of ecosystems like mangroves, and monitoring to prevent further land degradation and support sustainable agriculture.
