1. CARACTERIZACIÓN Y CUANTIFICACIÓN DE FRAGMENTOS DE BOSQUE NATIVO, EN UN SECTOR DEL SECANO INTERIOR DE LA REGIÓN DEL MAULE, CHILE
ABSTRACT In general, the Mediterranean forests have suffered high levels of fragmentation, mainly by anthropogenic action, as result of the productive activities of agriculture and livestock, human settlements and forest plantations of fast growing exotic species, leading to loss of continuity of natural forests, and thus a decrease of biodiversity. In this

2. MODELING OF WATER, SEDIMENT AND PHOSPHORUS LOADS IN AN AGRICULTURAL WATERSHED IN SOUTHERN BRAZIL / MODELAGEM DO ESCOAMENTO, DA PRODUÇÃO DE SEDIMENTOS E DA TRANSFERÊNCIA DE FÓSFORO EM BACIA RURAL NO SUL DO BRASIL
Areas under intensive tobacco crop cultivation have been impacting the water balance and increasing soil erosion in Southern Brazil. Application of large amounts of mineral fertilizers, higher than the tobacco requirement, contributes to excessive phosphorus loads in soil and water bodies. The assessment of potential environmental impacts due to changes in l

3. Analysis of landslides susceptibility and use and landcover evolution of Paraty City - RJ / Análise da suscetibilidade a escorregamentos e as implicações da evolução do uso e cobertura do solo no município de Paraty, RJ
The city of Paraty is located between the Angra dos Reis and Ubatuba municipalities, stages of a numerous episodes of landslides. As the neighboring cities is marked by the presence of the Serra do Mar, where the shallow landslides in the form of translational movements account for most of the evolution of relief. And yet, there is no reference to deaths ass

4. Algebraic modelling of spatiotemporal objects: understanding change in the Brazilian Amazon / Modelagem algébrica de dados espaço-temporais: entendendo as mudanças na Amazônia
This thesis proposes an algebra to describe how spatiotemporal objects evolve, named geospatial algebra, and a model to apply it. This algebra is composed of a set of operations, axioms and rules defined by the application. Specifically, we handle evolving objects, which are objects that evolve by changing their boundaries and attributes. These objects appea

5. Diagnóstico sócio-ambiental do entorno da Estação Ecológica de Águas Emendadas (DF)
The disordered growth of the urban nucleus and the increase of the farming areas have caused the reduction and fragmentation of natural environments at the Bioma Cerrado with consequent pressure on the conservation areas and other protected areas. This scenery is not different in the Distrito Federal and in its conservation areas where the Estação Ecológi

6. Land suitability, evolution and land use conflicts in Itaara county RS / APTIDÃO, EVOLUÇÃO E CONFLITOS DE USO DAS TERRAS NO MUNICÍPIO DE ITAARA, RS
The landscape is constantly altered by the man s action. The rational use of the natural resources and space it should be done in agreement with the natural vocation of the environment. For so much it is necessary the knowledge of the environmental attributes for a efficient planning of use. The purpose of this work was make the survey of the environmental a

7. Aspectos ecológicos e econômicos do plantio de Pinus elliottii Engelm var. elliottii como facilitadora da restauração de mata ripária em região de Cerrado (Assis, SP, Brasil) / Exotic species in forest restoration: ecological and economical aspects of using Pinus elliottii Engelm var. elliottii as pioneer in Cerrado region, Assis, SP, Brazil
Among the obstacles to the native forests restoration in Brazil we find the high costs of planting high diversity of native trees. Searching for reduction of costs and vegetation recovery acceleration, the use of a fast growing exotic species (Pinus elliottii var. elliottii) as pioneer was tested in a riparian area in the cerrado domain, at Assis municipalit

8. ANÁLISE ESPACIAL DA EVOLUÇÃO DO USO E COBERTURA DA TERRA NA SUB-BACIA HIDROGRÁFICA DO ARROIO ARENAL, SANTA MARIA/RS / SPATIAL ANALISIS OF THE LAND USE AND COVER IN THE HYDROGRAPHIC SUBBASIN OF ARROIO ARENAL, SANTA MARIA/RS
This work investigates the dynamics of the classes of land use and cover in the hydrographic subbasin of Arroio Arenal - RS, through the representation of spacetime processes. Spatial analysis of a distinct time series among the dates of October of 1995, May of 2000 and January of 2005 through a set of multisensor images was performed. It has generated repre

9. Exploring alternatives for the construction of neural spatial interaction models / Explorando alternativas para construção de modelos neurais de interação espacial
The rapid growth of Brazilian cities, without a previous planning of their expansion (including land use and occupation), causes many inconveniences for the population related to their transportation, as they must cover longer distances. This asks for an understanding of the city areas limits, the services currently offered to the community in each area, and

10. Land use and land cover evolution patterns in Rondônia Center-North region / Evolução de padrões de uso e cobertura da terra na região Centro-Norte de Rondônia
This work proposes a method to analyze the process of land use and land cover change partitioning the study region, considering spatial and temporal patterns extracted from visual analysis of historical series of TM/Landsat imagery. The study area is located at the Center-North region of Rondônia state, a pioneer region, where small settlements planned by I

11. Analyses of tornadoes events in Santa Catarina state, Brazil: synoptic features and datamining. / Análise de episódios de tornados em Santa Catariana: caracterização sinótica e mineração de dados
This work deals with the prevailing synoptic features associated to tornadoes events in Santa Catarina state during the 1976-2000 period. The analysis was done using the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis, satellite images from GOES-8 and TRMM and conventional meteorological data.

12. Evolution of the land use in portion of the occidental Amazon (Acre), with use of changes detention technique / Evolução do uso da terra em porção da Amazônia ocidental (Acre), com uso de técnicas de detecção de mudanças
The Brazilian Amazon has been objective of activities that are transforming extensive areas of humid tropical forest in areas destined to the agriculture and pastures, contributing to the alteration of the atmosphere and of the Amazon landscape. Starting from the decade of 60, the state of Acre, started to suffer great pressure through the migration and peop
