2. Mapping and characterization of intensity in land use by pasture using remote sensing
RESUMO A demanda atual por alimentos tem sido atendida por meio da exploração das reservas naturais. O Brasil apresenta 26% da sua extensão ocupada por usos agropecuários, sendo 62% desses, pastagens. Pastagens degradadas apresentam maior intensidade de uso da terra do que pastagens bem manejadas, levando à maior degradação do meio ambiente. Os sistem

3. Consequences of suppressing natural vegetation in drainage areas for freshwater ecosystem conservation: considerations on the new "Brazilian forest code"
The input of particulate and dissolved organic matter (POM and DOM, respectively) from terrestrial ecosystem drainage basins is an important energy and nutrient source in limnic food chains. Studies indicated that semi-deciduous seasonal forests located in drainage areas in Brazil have the potential to produce 7.5 - 10.3 Mg ha−1/year of POM. The global inc

5. Química Sem Fronteiras: o desafio da energia
Coal, natural gas and petroleum-based liquid fuels are still the most widely used energy sources in modern society. The current scenario contrasts with the foreseen shortage of petroleum that was spread out in the beginning of the XXI century, when the concept of "energy security" emerged as an urgent agenda to ensure a good balance between energy supply and

6. Avaliação econômica de uma operação de impacto reduzido em uma propriedade privada no estado amazônico de Rondônia / Economic evaluation of a reduced impact logging operation in a private property in the Amazonia State of Rondônia
Forests have economic, ecological and social irreplaceable functions, and much is speculated and investigated about the possibility of these resources simultaneously generate income and be preserved by means of reduced impact logging. In Brazil, a new regulatory framework was established in 2006 to regulate the management of public forests and the processes

7. Fundos soberanos de riqueza de recursos naturais e volatilidade cambial.
The goal of this paper is to empirically verify what the impact of the Sovereign Wealth Funds (SWFs) on the economic stability is. The natural resource SWFs have been a mechanism deployed by economies rich in natural resources to manage the incomes that come from the exploitation of such resources, aiming at objectives that range from savings for future gene

8. Aleopatia de fungos fitopatogÃnicos sobre plantas invasoras das culturas de soja e milho / Allelopathy of plant pathogenic fungi on invasive plants on the cultures of soybean and corn
Invasive plants can cause problems to the exploitation of agriculture worldwide. The chemical control of these plants has generated several environmental problems, such as the contamination of natural resources, the compromising the food quality, the poisoning of farmers, the development of the weedâs resistance, among others. An alternative to reduce the u

9. Caracterização de resíduos sólidos da construção civil para sua utilização em camadas drenantes de aterros sanitários / Characterization of construction waste for use as drainage materials in sanitary landfills
Intense population growth brings with it environmental concerns, since exploitation of natural resources, makes it essential to adopt recycling policies in order to achieve sustainable development. Therefore, this study sought to define a new application for recylcling construction and demolition waste (CDW-R). Two size distributions that could be readily pr
