Land-use change can be a factor in CO 2 (carbon dioxide) atmospheric concentration, and is thus a contributor to global climate change. [14] IPCC estimates that land-use change (e.g. conversion of forest into agricultural land) contributes a net 1.6 ± 0.8 Gt carbon per year to the atmosphere.
Planting trees in tropical climates with wet seasons has another advantage. In such a setting, trees grow more quickly (fixing more carbon) because they can grow year-round. Trees in tropical climates have, on average, larger, brighter, and more abundant leaves than non-tropical climates.
Carbon capture and storage (CCS) can be an option to reduce net emissions in these circumstances, although fossil fuel power plants with CCS technology is currently a high cost climate change mitigation strategy. [9] Human land use changes such as agriculture and deforestation cause about 1/4th of climate change.
Within the carbon capture and storage approaches, carbon sequestration refers to the storage component. Artificial carbon storage technologies can be applied, such as gaseous storage in deep geological formations (including saline formations and exhausted gas fields), and solid storage by reaction of CO 2 with metal oxides to produce stable ...
This means trees from monoculture planting that do not survive never reach full potential for carbon sequestration to offset China's carbon output. Overall, there is a possibility for afforestation to balance carbon levels and aid carbon neutrality , but several challenges still remain which hinder an all encompassing effort.
The planting of trees on marginal crop and pasture lands helps to incorporate carbon from atmospheric CO 2 into biomass. [29] [30] For this carbon sequestration process to succeed the carbon must not return to the atmosphere from biomass burning or rotting when the trees die. [31] To this end, land allotted to the trees must not be converted to ...
A forest soil carbon monitoring program to estimate soil carbon stock, using both survey and modelling-based methods, has also been undertaken. [34] Australia Australia established a A$200 million International Forest Carbon Initiative, focused on developing REDD+ activities in its vicinity, i.e., in areas like Indonesia, and Papua New Guinea.
