Hacia un sistema eficiente para la conservación de los bosques nativos : un análisis para los servicios ecosistémicos del Chaco Argentino

The Gran Chaco is one of the regions with greatest biodiversity in the world and one of the largest Latin American ecosystems, second only to the Amazon. Argentina has the largest portion of this region (58%) and statistics indicate that within the country it has been the ecosystem most degraded by deforestation over the las ten years. Furthermore, this region is among those with the greatest potential for agricultural development in the country and therefore sustainability issues are presented as a main challenge. In this context it is necessary to carry out an in-depth evaluation of existing  mechanisms in order to identify opportunities and define those tools that enable greater efficiency in  terms of sustainable management of ecosystem services for conserving the native forests in the  Argentine Chaco. For achieving this objective, in this work a definition and analysis of the main  economic theories that address the internalization of the benefits generated by ecosystem services are presented, as well as a diagnosis of the current situation of the Argentine Chaco, in order to develop  a proposal for generating an efficient system of payments for ecosystem services that ensures sustainability in the region.
