Espacialização do uso da terra da microbacia do Córrego Monte Belo - Botucatu (SP), obtido por imagem de satélite de 2011 e fotografias aéreas coloridas de 2000

O presente trabalho teve como objetivo avaliar as variações de uso e ocupação do solo entre os cenários de 2000 e 2011 da microbacia do córrego Monte Belo – Botucatu (SP). Para tanto, utilizou-se de geotecnologias, sendo a integração de informações realizada no Sistema de Informações Geográficas (SIG) - IDRISI, aliada ao uso de cartas digitais do IBGE, escala 1:50.000, além de fotografias aéreas (2000) e imagens de satélite LANDSAT - 5 (2011). Através dos dados obtidos, foram detectadas três classes de uso do solo sendo que em 2000, elas correspondem ao reflorestamento, pastagem e mata ciliar e em 2011, reflorestamento, mata ciliar e solo exposto. Desta forma, pode-se concluir que as ferramentas de análise baseadas em SIGs trazem a possibilidade de analisar as variações no espaço e no tempo além de resultar em informações que podem subsidiar o planejamento da microbacia do Córrego Monte Belo.

Sistema de Informações Geográficas aplicado ao diagnóstico do uso da terra da bacia hidrográfica do Córrego São Caetano - Botucatu (SP)

The study aimed to obtain the land use of the watershed Stream São Caetano - Botucatu (SP), through the satellite image. The cartographic databases were: planialtimetric letter in digital format (IBGE) used in georeferencing, and satellite image. Geographic Information Systems (GIS) -IDRISI Selva was use to perform the image georeferencing and to do the final thematic map. In the software CAD - CartaLinx, it was performed the delimitation of the area under study (boundary, drainage network and areas of use and coverage). The land use of the watershed showed that pasture was the class which occupied most of the area, with 34.51% (1117,94 ha), the remainder of the area was urban (692,19ha), forests (809,79ha), cultures (599,96ha) and a very small part of reforestation (19,53ha). The use of remote sensing and geoprocessing were very satisfactory in the present work. Technologies must be increasingly used in agricultural and environmental studies, because technological tools, such as Geographic Information System (GIS), present speed, efficiency, reliable results, helping in increasing sustainability

Análise multicriterial aplicado na definição de áreas prioritárias ao uso agrícola da terra da bacia do Rio Capivara, Botucatu, SP

The use of geographic information systems (GIS), combined with advanced analysis technique, enables the standardization and data integration, which are usually from different sources, allowing you to conduct a joint evaluation of the same, providing more efficiency and reliability in the decision-making process to promote the adequacy of land use. This study aimed to analyze the priority areas of the basin agricultural use of the Capivara River, Botucatu, SP, through multicriterial analysis, aiming at conservation of water resources. The results showed that the Geographic Information System Idrisi Selva combined with advanced analysis technique and the weighted linear combination method proved to be an effective tool in the combination of different criteria, allowing the determination of the adequacy of agricultural land use less subjective way. Environmental criteria were shown to be suitable for the combination and multi-criteria analysis, allowing the preparation of the statement of suitability classes for agricultural use and can be useful for regional planning and decision-making by public bodies and environmental agents because the method takes into account the rational use of land and allowing the conservation of hydrics resources.

Planejamento do meio físico a partir de uma abordagem da técnica de capacidade de uso da terra na sub-bacia dso Rio das Pedras - Itatinga - SP

The study aimed mapping of the land use capacity classes for the Rio das Pedras watershed, Itatinga-SP in order to provide another mechanism of environmental planning for the studied area. It was used 1:10,000 topographic letters for the slope map generation which was overlaid with the studied area soil map. It was applied the judgment table criteria method, for generation of land use capacity map of the studied area. It were identified the following results: First, class III with constraints in relation of low fertility and restrictions about erosion risks on high slope areas. Second, class VI with the same characteristics of class III however with the presence of an aggravating factor of sand texture in all horizons, resulting in high risks of erosion events, especially in high slopes areas, and contamination by pollutants due the high soil permeability. Conclusions: It was verified that the more critical regions for land use capacity classes were VIs and mainly VIes class. The last one has more high relief areas and the presence of Neossolo Quartzarenico soil, with a big erosion propensity. The land use capacity map allow making different decisions for each region of the watershed respecting their individual characteristics.

O clima em sua regulamentação político-econômica: o acordo de Copenhague - COP 15

We know that the Earth goes through natural cycles that influence its climate and the development of their societies. In recent decades, climate changes and nature began to call world attention to the unbridled exploitation that was carried by the current economic system, causing unrest among scientific, social, political and economic world. The theory that man causes a warming in global temperatures by the release of greenhouse gases made the headlines of major newspapers in the world. From there, it was only a matter of time before environmental concerns became ownership of capital by its excessive appropriation. The fear of nuclear threat by the bombs of Hiroshima and Nagasaki left in fanfare the world, which together with the devastating impact of the exploitation of man and nature gave birth to the Environmental Revolution, a way of trying to change the development patterns of the time and behavior of the population. However, based on the historical form of capitalist domination, this was another measure that was apossada the economic system being transformed into economic value and political exchange. The origin of the conventions, meetings, conferences, parliaments set up to discuss environmental issues, eventually became forums of political and economic talks focused on environmental governance, valuing an asset that is public and everyone. Environmental and climate issue now has a value, thus turning the agenda on the agenda of the United Nations (UN) for its political and economic regulation in the form of global agreement. Given the need for understanding the climate issue, was born the Conference of the Parties (COPs), a regulatory body for climate negotiations, surrounded interests, complexities, conflicts and disagreements between the parties countries, which becomes clear when we analyze their agreements...
