1. Caracterização ambiental e estimativa da produção de cargas difusas da área de drenagem da represa de Itupararanga, SP / Environmental characterization and estimative of diffuse pollution of Itupararanga watershed, SP
The use of satellite images has improved the study of the land use dynamics. Land cover mapping have become fundamental tools in the assessment of landscape changes caused by human action and its influence on regional and urban planning. Computation tools such as Geographic Information Systems and hydrological models have supported these findings. The hydrol

2. Banco de dados geológico-geotécnicos com base em sondagens à percussão e uso de SIG: análise espacial da profundidade do lençol freático e do \ N IND.SPT\ para obras de fundação em João Pessoa - PB / Geological-geotechnical Database with SPT sounding data and GIS: spatial analysis of water table level and \ N IND.SPT\ values applied to foundation maps in João Pessoa - PB (Brazil)
Geological-geotechnical databases have been used as important assistant tools in urban and environmental management activities. However, the kind of information necessary for one to work with such tools may not always be available or easily supplied. This work concerns the generation of a Decision Support System undertaken through means of a Geographic Infor

3. Mapeamento do risco de malaria utilizando variáveis ambientais e antrópicas
Despite much research in the identification of areas with malaria, it is urgent to further investigate mapping techniques to achieve better approaches in strategies to prevent, mitigate, and eradicate the mosquito and the illness eventually. By using spatial distributed modeling techniques with Geographical Information Systems (GIS), the study proposes metho

4. Assessment in the global warning context : case study Monjolinho rural basin, Piracicaba, São Paulo, Brazil / Avaliação de cenarios no contexto do aquecimento global : estudo de caso da bacia rural do Monjolinho, Piracicaba-SP
One of the global warming effects is the increase of extreme rainfalls, which can cause many negative impacts to rural areas, such as floods and erosion. So, it is important that an equitable land use is distributed along river basins, especially in the ones where there are agricultural fields, since it can help to minimize runoff and soil erosion caused by

5. Potencialidades de cultivo de macroalgas no litoral do Rio Grande do Norte (NE, Brasil): uma perspectiva de integração de dados ambientais em sistemas de informação geográfica (SIG)
Since centuries ago, the Asians use seaweed as an important source of feeding and are their greatest world-wide consumers. The migration of these peoples for other countries, made the demand for seaweed to increase. This increasing demand prompted an industry with annual values of around US$ 6 billion. The algal biomass used for the industry is collected in

6. Avaliação da largura ideal de Florestas Ribeirinhas considerando modelagem matemática, estimativa de erosão por ¹²³CS e aspectos ecológicos / Riparian Forest width evaluation using mathematical modeling,137Cs technique and ecologycal aspects.
The main hypotheses of the present study regarding the evaluation of the efficiency of riparian forest to sediment retention were: 1. Riparian Forest is an efficient system for sediment retention in watersheds; 2. Different Riparian Forests widths present different efficiencies for this function and, 3. Widths of riparian forests to sediment retention vary a

7. Modelo geogrÃfico para gestÃo de recursos hÃdricos na bacia do Rio Preto â Distrito Federal
The present dissertation deals with the development of a Geographic Model for Water Resources Management, with the purpose of assisting the decision taker and the planning about the grant of water uses, instituted from the Brazilian Law 9.433 of 1997, which deals the Water Resources National Politics. The studyâs object is located in Pretoâs river basin po

8. Geotecnologias como contribuição ao estudo do agroecossistema cafeeiro de Minas Gerais em nível municipal / Geotechnologies as contribution to the study of coffee crop agro system at municipal level in Minas Gerais state
Coffee crop, an important economic and social activity to Brazil, is an agrobusiness segment that has not updated information about the agroecosystem and the productive profile. In this sense, it was proposed in the year of 2004 a multidisciplinary and multi institutional project, involving INPE, EMBRAPA and UFLA to characterize the coffee agroecosystem in M

9. Avaliação das taxas de doses de radiação gama e modelagem cartografica das estatisticas de obitos por neoplasias na região central de Cuba / Evaluation of the gamma radiation dose rates and cartographic modeling of the death statistics by neoplasies in the central region of Cuba
This study developed in the central part of Cuba, attempted to evaluate a gamma radiation dose rate, exploring the airbome geophysical survey possibilities in order to obtain a radiogeochemical characterization and the geological - structural mapping of environment for an area of about 16.500 km2. Besides, to dispose through this research, of results that co

10. Water resources management: Environmental modeling with a preservationist scenario simulation / Gerenciamento de Recursos Hídricos em Bacias Hidrográficas: Modelagem Ambiental com a Simulação de Cenários Preservacionistas
The present study had the objective to implement a numeric computer simulation of the superficial flow of water and of the erosive processes, transforming a geographic information system into a realistic system of the time-space processes to analyze the risks of environmental hazards of the Arroio Grande watershed. Through the environmental modeling process,

11. Modelagem da distribuição potencial do palmiteiro (euterpe edulis Martius)em região montanhosa a partir de variáveis topográficas / Palm tree (Euterpe Edulis Martius)potential distribution modeling in a mountainous region based on topographic variables
The objective of this work is to produce a potential distribution model for the palm tree Euterpe edulis Martius. Two suppositions were considered: (1)the distribution of E. edulis is conditioned by a set of environmental variables; (2)given that the previous condition is true, it is possible to establish a predictive spatial model of these relationships in

12. Modelagem ambiental com tratamento de incertezas em sistemas de informação geográfica: o paradigma geoestatístico por indicação / Environmental modeling with uncertainty treatment in geographical information systems: the indicator geostatistical paradigm
The use of Geographic Information Systems (GIS)to model environmental phenomena limits decision-making processes because the products of GIS modeling, such as agriculture suitability and vulnerability to erosion maps or economic-ecological zoning, do not encompass quantitative information on data quality. Current GIS technology does not associate the notion
