Faced with population growth and intensification of the use of natural resources, Protected Areas (PA) and Indigenous Lands (IL) play a fundamental role in environmental conservation. The carbon increment of preserved vegetation within these areas is accounted for as CO2 removal in the Land Use, Land-Use Change, and Forestry (LULUCF) sector of the National Emissions Inventory. A topological evaluation of overlaps was made of the databases of PAs (full protection and sustainable use) and ILs, showing that they represent 6% of the protected areas. Of the total of PAs and ILs areas, 43% were established by 1994, 26% by 2002, 26% by 2010, and 4% between 2011 and 2016. This evaluation showed that 30% of the territory is within PAs and ILs. In terms of area, 84% is distributed in the Amazon, 9% in the Cerrado, 4% in the Atlantic Forest, 3% in the Caatinga, 0,2% in the Pantanal, and 0,3% in the Pampa. In assessing the use and cover of 2010 of the PAs and ILs created up to this year, it was possible to notice that 68% of the areas within the PAs have preserved vegetation, whereas in ILs, this percentage increases to 89%. Under the Third Emissions Inventory, the removal of vegetation protected in PAs and ILs decreased by 16% of the national net emissions of the LULUCF sector between 2002 and 2010, showing the importance of preserving forests and grasslands.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
