The land suitability evaluation is used to establish land zonings for agriculture activities. Geographic information systems (GIS) are useful for integrating different attributes necessaries to define apt and not apt lands. The present study had as main objective to describe procedures to define land suitability using GIS tools, soils maps and data soils profiles data, emphasizing procedures to define soil atributes. The area studied was the watershed of Córrego Espraiado, Ribeirão Preto-SP, located on the recharging area of the Guarani Aquifer, with approximately 4,130 ha and predominance of sugar cane culture. The database project was developed using the GIS Idrisi 32. The land suitability evaluation was done considering the intensive agricultural production system predominant in the watershed, adjusted for the vulnerability of the areas of recharge and for the methodology of GIS tools. Numerical terrain models (NTM) had been constructed for cation exchange capacity, basis saturation, clay content and silt+clay content using kriging (geostatistical interpolator), and for aluminum saturation using the inverse-square-distance. Boolean operations for handling geographic fields (thematic maps and NTM) to produce information plans are described and a land suitability map obtained by GIS tools is presented, indicating that 85% of watershed lands are apt to annual cultures.

This project was guided by a single question: if coastal or maritime forests are going to be developed, what advice can the S.C. Department of Natural Resources provide to minimize development impacts on wildlife and their habitats? To answer this question, this report will first provide a general description of the maritime forest’s biological community, including some of its typical plants and animals, as well as coastal species that are rare and possibly declining. This document provides information on the dominant habitats within, and adjacent to, maritime forest and some of the ecological relationships between plants and animals. And finally, the report provides guidelines on how to minimize impacts on wildlife while building a home in a wooded area.
