1. Physical, Chemical, and Microbiological Properties of Soil under Different Plant Covers in the Seridó Desertification Region in the Brazilian Semiarid
ABSTRACT The Seridó Desertification Region is a result of inadequate management of the native Caatinga vegetation, which generated degraded areas with little or no capacity for plant production. The area has experienced a succession of different land uses, but little is known about the impact of these changes. The present study tested the hypothesis that th

2. 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

3. Valoração, cobrança pelo uso da água e a gestão das bacias hidrográficas do Alto Iguaçu e afluentes do Alto Ribeira : uma abordagem econômico-ecológica / Valuation, charging for water use and managemente of Alto Iguaçu and tributaries of the Alto Ribeira watersheds : an economic-ecological approach
The degradation of the natural system throughout the century XX can be characterized by the upward trend and close relationship with the scale of economic activity, which requires increasing amounts of natural resources as a source of inputs as a source for the absorption of waste. Thus, what was once considered a good or service provided free by the natural

4. AVALIAÇÃO DAS POTENCIALIDADES DAS TERRAS, ADEQUAÇÃO DO USO DAS TERRAS E INDICADORES DE QUALIDADE DOS SOLOS: subsídios para o planejamento conservacionista no perímetro irrigado de Mirorós (Ba). / EVALUATION OF THE LAND POTENTIALS, LAND USE ADEQUACY AND SOIL QUALITY INDICATORS: subsidies for conservationist planning in the irrigated Perimeter of Mirorós (Ba).
The practice of irrigated agriculture represents an increase of agricultural productivity, especially for areas with water deficit. Lands are frequently characterized erroneously which, coupled with lacking conservation measures, imposes serious consequences for the environment. In reality, any land use and intensive soil management when carried out unsustai

6. Caracterización y monitoreo de paisaje semiárida en la Región del Maule mediante datos satelitales
The objective of this research is to apply the Radiometric Rotation Controlled by No-change Axis (RCNA) technique on Landsat TM images, 2004 and 2008, covering the coastal dry land of the Region of Maule, Chile, in order to obtain the spatial distribution of changes and degradation in the forest landscape. The RCNA procedure allows the use of images without

7. Soil fauna, arbuscular mycorrhizal fungi and diazotrophic bacteria in Areas of Mining of Bauxite in the Northwest Pará revegetated with palm oil. / Fauna do Solo, Fungos Micorrízicos Arbusculares e Bactérias Diazotróficas em Áreas de Mineração de Bauxita no Noroeste do Pará Revegetadas com Dendê.
The Mining is considered the activity can cause a great impact in the environment, involving the vegetation and subsoil layers remove. After the finish of mineral sources, mandatorily these areas require recovery measures. This study aimed to evaluate the initial establishment of three genotypes of palm oil: C2501, C2301 and C2528, indicated by Embrapa Amaz�

8. Environmental characterization of the Mogi Guaçu river upstream region (Bom Repouso - MG): replicability strategies and guidelines for drawing up the environmental adequation plan / Caracterização ambiental da região de montante do rio Mogi-Guaçu (Bom Repouso - MG): estratégias para replicabilidade e diretrizes para elaboração do plano de adequação ambiental
The upstream region of the river Mogi Guaçu is considered strategic regarding the water issue, with hundreds of springs that contribute to the formation of brooks and streams and which enable the multiple uses of water in cities located in the states of Minas Gerais and São Paulo. Considering this, we tried to carry out an environmental diagnostic (between

9. Caracterização física, estrutural e da diversidade floristica de fragmentos florestais na alta bacia do Rio Araguaia
The upper Araguaia river basin region has been transformed by rapid and intensive human occupation processes that began in the 1970s, and now the landscape is highly fragmented. Remnant forests are surrounded by cotton and soybean plantations and pasture. They continue to be subjected to degradation and little is known about their ecological integrity. The o

11. Soil quality in native forest and pasture eco-systems in the eastern Acre region of Western Amazon / Qualidade do solo em ecossistemas de mata nativa e pastagens na região leste do Acre, Amazônia Ocidental
The state of Acre is presently at the initial stage of converting its forests into pastures. Around 12% of its total area (19.200 km2) has been deforested. Out of this, approximately 81% (13.352 km2) have been utilized by several productive segments in Acre (farmers, land settlers, extractivists, riverine farmers and cattle producers), with extensive pasture

12. Dinâmica do uso dos recursos hídricos nas bacias do ribeirão Entre Ribeiros e do rio Preto, afluentes do rio Paracatu / Water resources use dynamics in watersheds of Ribeirão Entre Ribeiros and Rio Preto, tributaries of the Paracatu River
From times past, humanity confronts problems of environmental degradation. The environment, which always performed efficiently its function of filtration, today finds itself excessively overburdened by human activities: it suffers the risk of its resources exhausting, not being able in certain situations to recuperate itself and needing the help of man. Howe
