Soil carbon sequestration is a natural and effective mechanism for mitigating climate change by capturing and storing atmospheric carbon dioxide in soil organic matter. Healthy soils act as major carbon sinks through processes such as plant residue decomposition, root biomass accumulation and microbial activity. Sustainable land-use practices (including conservation tillage, crop rotation, cover cropping, agroforestry and organic amendments) enhance soil carbon storage while improving soil fertility, water retention and biodiversity. By strengthening ecosystem resilience and supporting sustainable agriculture, soil carbon sequestration offers a cost-effective, nature-based solution to reduce greenhouse gas concentrations and combat the adverse impacts of climate change.
