Research interests:

The development of methods aimed at capturing deforestation, forest degradation and the effects of conservation measures, sustainable management and evolution of carbon stocks in developing countries are essential, as the data produced in this context feeds into information mechanisms developed under the United Nations Framework Convention on Climate Change (UNFCCC) and other post-Kyoto Protocol programs. These are essential not only in the establishment of investment mechanisms related with the carbon market, including those who seek to avoid deforestation and forest degradation in developing countries, while promoting their development through sustainable management and conservation of forest resources, but also in decision support and development of strategies that promote climate change adaptation and mitigation in these countries.

:Core research
Use of remote sensing data for mapping and quantifying the status and changes in the biophysical characteristics of forests in relation to anthropogenic land use and climate change.
