The Ecological-Economic Zoning (EEZ) is a territorial management instrument, a king of territory organization in zones which indicate activities that consider its potentialities and fragilities. The research analyzed in an integrated way the landscape of Rio Preto’s watershed, located in the south of Goiás State (Brazil) with the objective of proposing a zoning which ally environmental preservation and socioeconomic development. From the landscape analysis, five zones were delimited: 1) zone of restrict use (32%), characterized by remaining vegetation areas, slopes with strong/very strong dissection and hydromorphic soils; 2) urban industrial expansion one (0.53%); 3) consolidated sugar-energy production zone (19.47%), area which a power plant and its respective areas of sugarcane crops are localized; 4) zones of agrosilvopastoral use I (18%), characterized for being favorable to grains cultivation, forestry and pasture; 5) agrosilvopastoral zone use II (30%), with the same characteristics of the previous zone, however with the possibility of expansion of sugarcane plantation. It was proposed the creation of a belt of preservation unities taking advantage of the mountains, besides establishing ecological corridors all over Rio Preto, which would result in an average deadline on the water production increase.
