Research interests

My research is centered on the development of concepts and tools for understanding and implementing long term adaptation of social-ecological systems in a changing world.

I use a variety of concepts and tools from the fields of ecology, population genetics, statistics and comparative public policies to address the dynamics of social ecological systems from an interdisciplinary point of view. In my research, public policies act as the main external perturbation that conditions ecosystem trajectories.

In temperate forests, I have been analyzing the concept of ’assisted migration’ or ’assisted colonization’ as means to compensate for the effects of climate change. This work is centered in its legal, operational aspects based on tree population data and the actor’s perception of the strategy.

I am currently expanding my research to tropical areas, to examine the implications of the aggressive public policies promoting agroforestry in Latin America. These policies framed as an option for climate change adaptation have large uncertainties regarding their true effects in stabilizing climates, protecting local biodiversity and providing long term stable income for rural populations. The areas I am looking at are the Equatorial countries in Latin America (Colombia, Ecuador and Peru).

key words:

interdisciplinary research, forest social-ecological systems, public policies, climate change, anthropocene.

I lecture mostly at the Master’s level in topics related to forest genetic ressources and climate change and about the structure and dynamcs of social ecological systems.
