Carbon sequestration is the process of capture and long-term storage of atmospheric carbon dioxide and refers to
The process of removing carbon from the atmosphere and depositing it in a reservoir. When carried out deliberately, this may also be referred to as carbon dioxide removal, which is a form of geoengineering.
The process of carbon capture and storage, where carbon dioxide is removed from fuel gases, such as on power stations, before being stored in underground reservoirs.
Natural biogeochemical cycling of carbon between the atmosphere and reservoirs, such as by chemical weathering of rocks.
The emphasis of land use systems that have higher carbon content than existing plant community can help achieve net gains in carbon, specifically and significant increases in carbon storage can be achieved by moving from lower biomass land uses [e.g. grasslands, crop fallows, etc] to tree based systems such as forests, plantation forests and agroforestry. Agroforestry provides a unique opportunity to combine the twin objectives of climate change adaptation and mitigation. Although agroforestry systems are not primarily designed for carbon sequestration, there are many recent studies that substantiate the evidence that agroforestry systems can play a major role in storing carbon in aboveground biomass and in soil and in belowground biomass. Some of the earliest assessments of national and global terrestrial carbon dioxide sinks reveal two beneficial attributes of agroforestry systems (a) direct near term storage [decades to centuries] in trees and soils and (b) the potential to offset immediate GHG emissions associated with deforestation and subsequent shifting cultivation. Estimating the potential of agroforestry systems given the multiple benefits of such systems and the potential to provide synergy between climate change mitigation and adaptation by way of decreasing the vulnerability of communities to climate risks and climate change in the long run.
