Mosaic restoration may be easier to undertake as it allows a greater range of land uses, whilst restoring areas to closed-canopy forest is likely to remove more C02 per unit of area. Depending on ecosystem type, and whether the result is a natural forest or a plantation, areas converted to forest are estimated to remove between about 1 and 35 tCO, per ha per year in above- and below-ground biomass (from default data in IPCC (2006)7). The IPCC states with high confidence that increased atmospheric CO, will lead to increased terrestrial carbon uptake (Ciais et at, 2013), and a recent review suggests that the largest increase has been in woody biomass within savanna (included in some national forest definitions) and non-forest ecosystems (Liu et at, 2015). Carbon sink figures for existing forests are not included in the technical potential for reduced deforestation given here, as a result of the uncertainty surrounding how carbon sinks and their capacity to absorb C02 will change in the changing climate (Bellassen and Luyssaert, 2014).
