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 Linking Landscape with Human, Economic Measuring landscapes Venezuela and Ecological Environments Guyana Surinam Eco-efficiency Colombie Guyane Roraima Amapa CAQUETA ECO-EFFICIENCY index Para In 54 farms from 2 countries and 6 Équateur PACAJA landscape windows with different colonisation MACARANDUBA Maranhao Ef = Pe * Sq * Bd Amazonas ages and histories, 14 fully compatible Pérou Acre PALMARES II With datasets describe SOCIOECOnomic Rondonia Pe = income $/ha used/labour UTE AMAZ sites Tocantins conditions, LANDSCAPE metrics, Mato Grosso Sq : soil quality (GISQ index; Bolivie BIODIVERSITY (7 groups), PRODUCTIONS Goias Velasquez et al., 2007) 0.1 to 1. and ECOSYSTEM SERVICES Bd : Biodiversity index (0.1 to 1.0) Significant covariations (Multiple Coinertia Analysis) I 6600 $ NC: SOCIOECO 15 Ha 0.70 Socio 2.0 persons Plot History Production Demography GISQ 0.74 Systems 0.60 0.44 0.42 0.37 0.47 0.42 EF=68.4 INC: 7500 $ 0.50 49 Ha LANDSCAPE 2.2 persons Structure Composition 0.40 INC: 11200 $ 0.44 GISQ 0.53 105 Ha 0.30 EF=41,6 1.8 persons 0.40 GISQ 0.54 0.28 0.38 0.20 EF=37,3 BIODIVERSITY 0.10 0.35 0.36 0.30 0.39 0.0 0.35 0.33 GISQ AGRO SYLVO CONVENTIONAL SOIL C in PLANT 0.38 BIOMASS FORESTRY Aggreg.
