Presentation<br />
The government of the State of <strong>Tocantins</strong> has been able to account for<br />
environment in public policies planning and management. Through the Ecological<br />
and Economic Zoning Programme, considered the State´s strategic point in order to<br />
make it possible to go further into economic development with environmental protection<br />
and conservation, SEPLAN has efficiently generated products that support <strong>Tocantins</strong><br />
in its land management.<br />
Seeking to increase the list of products made available to society and<br />
municipal, state and federal agencies through the Ecologic and Economic Zoning<br />
Programme, I present now the work “Geomorphology SB-22-Z-B (Xambioá)”, which<br />
was obtained after financial efforts from the State Treasure, the G7 Pilot Programme<br />
to conserve the Brazilian Rain Forest (PPG-7), through the Environment Ministry,<br />
and the World Bank.<br />
The study of geomorphology, <strong>do</strong>ne at low cost, had as main tools<br />
satellite imagery, SEPLAN´s data base and cartographic products from<br />
RADAMBRASIL, completed with field surveys. Over this information a metho<strong>do</strong>logy<br />
to classity relief and characterize landscape based on its vulnerability to soil loss<br />
was applied. This brought the definition of three Morpho-structural Domains, two<br />
Geomorphological Regions and three Geomorphological Units. The main objective of<br />
this study was to generate information that had enough quality and the necessary<br />
quantity to achieve the Ecological and Economic Zoning of Bico <strong>do</strong> Papagaio.<br />
Summarizing, the present study momentarily supplies the gap of<br />
traditional surveys at scale 1:250.000, being a contribution given by this SEPLAN<br />
towards a better understanding of the natural resources of State of <strong>Tocantins</strong> and<br />
support to land management.<br />
