Carbon Sequestration in Agroforestry: Enhancement of Both Soil Organic and Inorganic Carbon

In India owing to its gradation in climatic conditions from temperate to humid tropics, the agroforestry systems (AFS) and practices are highly diverse within the country. The agroforestry practices followed in India range from intensified simple monoculture systems of planting, such as block and boundary plantations, to more specific, diversified, and complex systems, such as home gardens. In the era of changing climate, the role of trees, and other vegetation, its abatement is of paramount significance. Agroforestry as a sustainable land management system has a major role in carbon conservation and sequestration. Agroforestry practices sequester carbon both above ground as well as belowground. The above ground carbon sequestration by vegetation which sequester atmospheric carbon undergoing various physiological process and conserve it as biomass. The sole terrestrial pool where carbon (C) may be intentionally increased by agroforestry practices is the soil organic carbon (SOC) pool, which has been able to store some carbon for millennia. Agroforestry systems sequester about 2233 g carbon both above and below ground during the period of 50 years, but estimates of the amount of land they occupy globally are highly uncertain.
