A Intensidade da Exploração Agropecuária como Indicador da Degradação Ambiental na Região dos Cerrados, Brasil AgEcon
Cunha, Nina Rosa da Silveira; Lima, Joao Eustaquio de; Gomes, Marilia Fernandes Maciel; Braga, Marcelo Jose.
Being constituted as the largest risk factor and effective degradation to the Savannah, the man’s intervention in the nature and, especially, the agricultural exploration require analysis and better monitoring. This work aims to analyze the relationship between the agricultural exploration and the environmental degradation in the area of the Savannahs, in 1995-1996. In particular, it is intended, to use multivariate statistical analysis, to verify the factors associated with the intensity of farming predominant in the determination of the degradation pattern, and to obtain indexes of exploration intensity to make possible to categorize and to group the microrregions in terms of degradation potential. The results showed that the intensity of the...

Anurans of a threatened savanna area in western Brazil Biota Neotropica
Sugai,José Luiz Massao Moreira; Terra,Juliana de Souza; Ferreira,Vanda Lúcia.
The Upper Paraguay River Basin is located in the center of South America and harbors one of the largest wetland in the world, known as Pantanal. This floodplain is surrounded by uplands, which presently have most of their area converted into pastures or monocultures, besides being poorly known scientifically. Also, most of these upland areas are considered conservation priorities. Here we present a list of anuran species from a savanna-like area (municipality of Camapuã, state of Mato Grosso do Sul, Brazil) inserted in the uplands surrounding the Pantanal floodplain, in the Upper Taquari River sub-basin, and evaluate the effectiveness of the sampling effort. Data were obtained through active searches in 22 plots in aquatic habitats, during the rainy season...

GUARINO, E. de S. G.; OLIVEIRA, L. C. de; SILVA, E. R. da; FARIAS, M. S.; PELLICCIOTTI, A. S.; THOMPSON, R. M..
A lei de proteção à vegetação nativa, n° 12.651/2012 (antigo Código Florestal Brasileiro), traz algumas inovações importantes para a proteção e conservação da biodiversidade da flora brasileira. Uma delas é a criação do cadastro ambiental rural (CAR), o qual tem como um dos objetivos apoiar o planejamento do imóvel rural, contribuindo para recuperar áreas degradadas, formar corredores ecológicos e conservar os demais recursos naturais (p. ex.: água e solo). Como resultado do CAR, todos os produtores rurais com passivos ambientais documentados após o dia 22 de julho de 2008 (data da regulamentação da lei de crimes ambientais) são obrigados a regularizar a situação de suas propriedades por meio do Programa de Regularização Ambiental (PRA). O Acre foi um dos...

Coralline Algae, Important Coral-reef Builders Threatened by Pollution OceanDocs
Mohammed, S.M.; Björk, M.; Björklund, M.; Semesi, A..
The release of inorganic nutrients into the sea by domestic sewage is a major threat to many marine systems. This eutrophication affects coral-reef organisms indirectly by increased growth of microalgae, leading to increased sedimentation, decreased light availibility, rapid growth of opportunistic macroalgae, etc. In this paper, we report a decrease in the cover of important group of coral-reef builders, the coralline algae. This decrease might be caused by the outlets of sewage water from Zanzibar town. Laboratory and field experiments show that both the growth rate and the calcification of these organisms are negatively affected by high phosphate levels, but not by nitrate or ammonia.

Cost-Effectiveness of Water Conservation Measures: A Multi-level Analysis with Policy Implications AgEcon
Blanco-Gutierrez, Irene; Varela-Ortega, Consuelo; Flichman, Guillermo.
Groundwater in Spain, as in other arid or semiarid countries worldwide, has been intensely used for the expansion of irrigated agriculture. This booming development has induced a remarkable socioeconomic development in many rural areas but has produced far-reaching environmental problems. In the Spanish Western La Mancha Aquifer, the excessive, and sometimes illegal, water abstraction for irrigation agriculture has resulted in the Aquifer’s overexploitation and has been responsible of the degradation of the associated wetlands “Tablas de Daimiel”, an internationally reputed, Ramsarnominated aquatic ecosystem. To undertake this analysis, a mathematical programming model has been developed to simulate farmers’ behaviour and their responses to different water...

Desenvolvimento econômico e Desmatamento na Amazônia Legal: Uma Análise Econométrica AgEcon
Gomes, Sergio Castro; Braga, Marcelo Jose.
O objetivo deste trabalho é testar empiricamente a hipótese ambiental de Kuznets aplicada ao relacionamento entre a taxa de desmatamento e a renda per capita nos estados da Amazônia Legal, além analisar o comportamento da taxa de desmatamento e da dinâmica populacional no período de 1990-2004. O teste econométrico utilizado para avaliar a hipótese ambiental de Kuznets é baseado na estimação de dois modelos específicos de regressão, o primeiro representa uma função quadrática e o segundo uma função cúbica, em que a taxa de desmatamento é a variável explicada, e a renda per capita, a densidade demográfica e o ano são as explicativas. Na estimação dos parâmetros utilizou-se a modelagem de dados em painel para efeitos aleatórios. Os resultados mostram que para...

Efeito da alteração ambiental sobre comunidades de Odonata em riachos de Mata Atlântica de Minas Gerais, Brasil Zoologia
Ferreira-Peruquetti,Patrícia Santos; Marco Jr.,Paulo De.
The effect of riparian deforestation and stream impoundments on an odonate community was studied in áreas of surviving Atlantic forest in Viçosa and in Rio Doce State Park (PERD), Marliéria, Minas Gerais, Brazil. During 1997 16 species of Libellulidae, 4 Coenagrionidae, 2 Gomphidae, 2 Calopterygidae, 1 Megapodagrionidae, 1 Aeshnidae and 3 Protoneuridae were collected. In Viçosa, the association of sampled odonates with lotic or lentic systems, and in PERD for areas with or without riparian vegetation were compared. The results suggest that although overall odonate taxonomic richness is high in areas without riparian vegetation. Likely, because productivity increase of such areas and its invasion by lentic Odonata species.

Effect of sea water and humidity on the tensile and compressive properties of carbon-polyamide 6 laminates ArchiMer
Arhant, Mael; Le Gac, Pierre-yves; Le Gall, Maelenn; Burtin, Christian; Briancon, Christophe; Davies, Peter.
Thermoplastic matrix carbon fibre composites offer considerable potential for underwater applications. Various material options exist but there are questions concerning the tension/compressive behaviour and water sensitivity of the less expensive polymers (e.g. polyamides) for these applications. The aim of the current work is to model water diffusion and its effect on the mechanical properties of thick carbon fibre reinforced polyamide-6 composite cylinders immersed in sea water for deep sea applications. To provide the data for such a model, thin specimens (2 mm thick) have been aged under different humidity conditions and tested in tension and compression. As water enters the composite, a significant reduction in the laminate properties is observed. An...

Environmental Changes on Inhaca Island, Mozambique: Development versus Degradation? OceanDocs
Muacanhia, T..
Inhaca archipelago is located ca. 32 km east of Maputo City, the capital of Mozambique. Inhaca Island (42.5 km2) and Portuguese Island (3.7 km2) constitute the small archipelago. Shoreline changes and sheet erosion are serious environmental problems affecting the archipelago today. Shorelines are constantly moving and changing. During rain season (October-March), strong winds, violent surf and stormy weather cause large powerful waves that induce changes on shorelines. As these waves pound the beach, sand erodes and is deposited offshore and the beach narrows. In dry season (April-September), waves and winds wash over the beach, bringing back the sand and gradually, the beach becomes wider. The major problems of Inhaca and Portuguese islands fringing...

Environmental Degradation and Intrahousehold Labour Time Allocations in Rural South Pare Highlands, Tanzania AgEcon
Dimoso, R.; Antonides, G..
We assess the influence of environmental degradation on intrahousehold labour time allocations in rural south Pare, Tanzania. We distinguished three types of areas, namely, severely degraded, medium degraded and non-degraded environmental conditions. The unit of analysis is the household composed of both parents and at least one schoolchild. The results, among others, show that environmental products collection and/or grazing time by the household members is, almost in all groups and in accordance to gender-biased activity, significantly influenced by the environmental conditions.

Exploring durability of interfaces in flax fibre/epoxy micro-composites ArchiMer
Le Duigou, Antoine; Davies, Peter; Baley, Christophe.
The influence of wet aging on the behaviour of flax/epoxy micro-composites composed of single flax fibres embedded in epoxy micro-droplets has been studied. Interfacial shear strength has been examined by debonding the micro-droplets. The apparent interfacial shear strength decreases with immersion time in water, dropping rapidly during the first 15 min of immersion then stabilizing. Drying samples after short immersion periods allows recovery of properties, indicating a plasticization mechanism. For longer immersion times irreversible degradation is observed. Scanning electron microscopy reveals fibre surface peeling, indicating that an internal interface within the fibre is weaker than the fibre/matrix interface after aging. A simple descriptive model...

China is undergoing economic growth and expansion to a free market economy at a scale and pace that are unprecedented in human history. This is placing great pressure on the country’s environment and cultural diversity. This paper examines a number of case histories in China, focusing on the culturally varied and ecologically diverse southwest region of the country. We show how developments in recent Chinese history have devalued and in some cases eliminated indigenous knowledge and practices in the quest to strengthen the centralized state. Despite these changes, more than 30 ethnic minorities live in southwest China. For generations these peoples have maintained landscapes through traditional land use and cultural practices. This indigenous...
