This project will contribute to scientific and technical knowledge on carbon storage in tropical forests as a value criterion for rural timber producer communities; furthermore, it will expand the information used for government decisions on forest sustainability policy in Mexico. Therefore, the main objective of the project is to develop a method to generate actual carbon storage figures for broadleaved forests in the Yucatán Peninsula, so that each community has a specific overview of the conditions on their lands, and of the intrinsic value of the forest. This will make it possible to measure stored carbon losses or gains, as a criterion for PES validation in the region. Significantly, this region is the largest carbon sink in the country, but it is also affected by considerable rates of deforestation resulting from forest fires caused mainly by human action. The project will work under a participatory and inclusive approach, with respect to the communities of this region. This in turn, will enhance the sustainability objectives shared by ITTO, REDD+, PECC and the National Development Plan of Mexico.
