Much efforts is done to conserve tropical rainforests through REDD and other
conservation mechanisms. We argue that an efficient way to conserve forests
and respond to the economic and environmental challenges of Global Change is
creating ecoefficient landscapes in already deforested areas.
The AMAZ project provides clues to this approach

SOCIOECO conditions landscape level
• is the template for Biodiversity • greatly varies among production
• and the basis for production of systems and landscapes
Ecosystem Goods and Services • can be enhanced at changing
