Subsídios a construção do plano de manejo da bacia hidrogáfica do Rio Irituia no município de Irituia-Pará

A utilização dos recursos naturais de forma irracional tem causado uma preocupação crescente em todas as regiões do planeta. Sugerir estratégias que compatibilize o desenvolvimento com preservação desses recursos torna se o principal desafio da gestão ambiental. Os recursos hídricos por serem amplamente utilizados e essenciais à vida necessitam de gerenciamento para garantir sua manutenção. No município de Irituia, localizado no nordeste paraense, a ação antrópica na paisagem natural, inclusive na mata ciliar (Área de Preservação Permanente), para produção agrícola, pastagem ou extração madeireira, tem ocasionado sérios problemas ambientais e socioeconômicos, como o assoreamento de rios, isolamento nas comunidades, prejuízo causados com as constantes enchentes dos rios, entre outros. A população local, juntamente com o poder publico municipal, reconhecem o dano ambiental e social causado nas diversas comunidades do município com anos de desmatamento, desta forma esta pesquisa fornece subsídios para elaboração do plano de gerenciamento da bacia hidrográfica no rio Irituia fornecendo instrumentos e ações sócio educacionais para reverter o quadro de degradação e propor a recuperação deste importante ecossistema.

Análise ambiental em um canteiro de obras

The building sector can cause the environmental degradation, by the natural resources consumption, machinery use and natural landscape modifying. The environmental management system (EMS) improves the environmental quality and makes the companies more competitive. So, this work developed an environmental management system in a building site focused on the solid waste and in the development of mitigation proposals for the most significant environmental impacts. To develop this work it was necessary to follow the building site activities; evaluate the solid waste management; identify the law requirements; identify the environmental aspects and impacts; evaluate the environmental impacts; and propose alternatives for mitigating the adverse environmental critical impacts. The main proposals are the reduction of the waste generation in the place that it’s generated; the reuse and correct final disposal of that wastes; the treatment and reuse of the effluent; and the supervising in the trucks and machineries avoiding the oil spilling and the air pollution

Análise do conforto térmico da cidade de Mirandópolis/SP em seus espaços abertos

Mirandópolis/SP appeared in 1934 from the railroad “the Brazil Northwest”, that there it served one of the points of its stretch that had as main function to drain the agricultural production northwestern native of São Paulo of that time. The installation of the town happened absent of concerns with initial urbanístico planning, thus modifying its natural landscape and modifying characteristic ambient without compensatory measures aiming at a future expansion of the urban mesh. Fact this that still causes today consequences the quality of life of the people and also the observed thermal comfort later. Ahead of this, the present work had for objective to identify through measurements of temperature and relative humidity of the city of Mirandópolis/SP the differences that in the fabric urban they corroborate for a comfort situation or thermal discomfort to the outdoors in accordance with the Diagram Bioclimático de Olgyay the collection of data was made throughout the month of July of 2011 involving the attainment of information of Temperature and relative humidity of air and questionnaire applied to the passer-bys in the act of the measurements. Also approaching the different thermal dynamic of the zones of housing in relation to the Urban Cannyon that develops the commerce as predominant activity. This research sample that, although a city to be small, the quality of life of its inhabitants is not only guaranteed by the transport or that its thermal comfort reveals inside homogeneous of the urban perimeter, but that it has yes heterogeneidade in the scope of the urban climate in these spaces

Caracterização do uso da terra em diferentes épocas na bacia hidrográfica do ribeirão paraíso- são manuel sp, por meio de sistemas de informações geográficas

This study aimed to evaluate a period of 38 years, the use and soil occupation of the Paradise River watershed, inserted in the citys of São Manuel and Areiópolis-SP using aerial photographs for the year 1972 and TM image (Thematic Mapper) obtained by the Landsat-5 satellite, in 2010, using geoprocessing techniques. The watershed in question is very important for the city of São Manuel-SP, because its urban area is inserted in its divisors which part of it belongs to the Environmental Protection Area (APA) Perimeter Botucatu-SP, considered a recharge area of the aquifer Guarani. Today, the development of agriculture faces challenges, which is to produce more food without impacting the environment. Allied to this concern, research institutions have sought new technologies that allow the detection and quantification of human actions, enabling interventions in order to minimize possible damage to the environment. Among these technologies can be cited Geographic Information Systems (GIS), which a large volume of data and information stored in a region at different times can be evaluated in the same time, suggesting different approaches to the planning of land use. The results of the mapping of areas of use and soil occupation result nine classes in 1972, and the coffee culture showed the biggest occupation (37.94%) of the total area. The 2010 mapping formulated twelve classes of use, which demonstrated the predominance of sugar cane (37.94%), on the areas occupied by coffee and pasture before. The land use maps of 1972 and 2010 showed results that show intense human activity in the modification of natural landscape.

Comparing assemblages of Asteraceae and their insect herbivores under different land-use regimens

Accelerated tropical landscape changes occurring over recent decades have produced environmental mosaics comprising remaining isolated green areas and mixed land-use types. Our objective was to study the effects of alterations in the natural landscape on the species composition and structure of assemblages of Asteraceae and their endophagous insects through comparisons between cerrado (savanna), pastures and Eucalyptus stands. We first investigated whether similarities between assemblages of Asteraceae and their insects varied among land uses or localities. Secondly, we asked whether assemblages of Eucalyptus stands and pastures are subsets of those within the cerrado. We sampled within randomly deployed transects in 15 areas. Land use was found to be an important factor in determining plant composition similarity; however, locality did not exert any significant influence. Pastures were less similar to one another, suggesting high beta diversity. Similarities among insect assemblages were correlated with plant assemblage composition, but not with land use or locality. Species of Tephritidae were distributed along localities independently of land use. High beta diversity in Asteraceae assemblages among cerrados and pastures was supported by nestedness analysis. Plant assemblages in Eucalyptus stands were subsets of cerrado, but pasture assemblages were only partial subsets. A higher degree of nestedness in insect assemblages than in plant assemblages indicated lower beta diversity within these herbivores. Our data indicate that many herbivores are specialized on widely distributed plant genera. Conservation of Asteraceae species and their flower head insects depends not only on maintenance of landscape fragments but also on the correct matching of management form and land use. Such management may contribute to reducing isolation of plant and insect species by increasing the connectivity of remaining cerrado tracts, allowing population maintenance even at low abundances.

A pocket beach that reaches equilibrium after becoming disconnected from a large system of beaches. Playa Barca (Fuerteventura)

[EN] Playa Barca is a 370 m long beach located within the system of the Leeward beaches on the Jandía peninsula, Fuerteventura. This system of beaches represents one of the major sources of economic income to the island, both because of its natural landscape that attract a specific type of tourism, and because of its particular climate conditions that make these beaches ideal for practicing wind-water sports. Nevertheless, in the past decades, this area has suffered from a significant and worrying coastline retreat. In order to look for an explanation to this retreat, five topographic surveys were carried out in October 1999, February 2001, February 2002, February 2003 and February 2013 to track the beach behavior in the last 15 years. A total station Topcon GTS-303D was used for this purpose. Surveys were carried out during low spring tides, so that the outer limit was the furthest possible depending on wave conditions. The inner limit covered part of the dunes in the backshore. From these topographic data both coastline changes and the sedimentary balance have been obtained.
