What are the ways of carbon sequestration in agriculture and difference between restorative and regenerative agriculture?
Restorative agriculture is mainly concerned with the restoration and rejuvenation of agricultural fields that have been deteriorated. Its objective is to restore the health, fertility, and structure of soil that has been depleted or harmed by conventional farming methods. Restorative agriculture employs several key methods to promote soil health and ecological balance. These strategies include minimizing soil disturbance and erosion by lowering tillage, enhancing soil organic matter and nutrient cycling by adding cover crops, and promoting biodiversity and ecosystem services through the implementation of agroforestry or silvopasture systems. Regenerative agriculture surpasses mere repair by actively revitalizing and enhancing the well-being and adaptability of agricultural ecosystems. The strategy adopts a comprehensive perspective, aiming to imitate natural ecological processes and improve the storage of carbon in soil, the diversity of species, and the functioning of ecosystems. Regenerative agriculture prioritizes techniques like rotational grazing, integrated crop-livestock systems, and agroecological principles to gradually enhance soil health and fertility. Furthermore, it gives priority to carbon farming methods that aim to capture and store atmospheric carbon dioxide in the soil. This not only helps to combat climate change but also improves the ability of the soil to withstand drought and other environmental pressures. While both restorative and regenerative agriculture share the goal of improving soil health, biodiversity, and ecosystem services, regenerative agriculture takes a more proactive and comprehensive approach. It places a strong emphasis on carbon sequestration, enhancing biodiversity, and replicating natural ecological processes. Restorative agriculture, in contrast, focuses primarily on revitalizing deteriorated lands through specific interventions and practices.

Carbon sequestration in agriculture involves capturing and storing atmospheric carbon dioxide in soil, plants, and other vegetation. Key methods include no-till farming, cover cropping, agroforestry, and managed grazing. No-till farming minimizes soil disturbance, preserving organic matter and enhancing soil carbon storage. Cover cropping, which involves planting crops like legumes or grasses during off-seasons, prevents soil erosion and adds organic matter to the soil. Agroforestry integrates trees with crops and livestock, increasing carbon storage in both vegetation and soil. Managed grazing rotates livestock to prevent overgrazing, promoting plant growth and soil health.
Restorative agriculture focuses on repairing and rehabilitating degraded lands to return them to a more productive and healthy state, often emphasizing soil health and ecosystem recovery. Regenerative agriculture, while also aiming to improve soil health and ecosystem function, goes further by adopting holistic, sustainable practices designed to restore, renew, and revitalize the entire agricultural system. This includes enhancing biodiversity, improving water cycles, and increasing resilience to climate change, making regenerative agriculture a more comprehensive approach that continuously enhances the agricultural ecosystem.
