Este estudo foi conduzido no Município de Jaboticabal, SP, com o objetivo de avaliar a evolução temporal e o número de fragmentos florestais no período de 29 anos, utilizando-se técnicas de sensoriamento remoto e fotointerpretação. Para a elaboração dos mapas foram utilizadas Cartas do IBGE de 1971 e fotografias áreas de 2000. Os resultados apontaram diminuição das áreas de floresta. em 1971, o município apresentava 3,63% da área total com fragmentos florestais, e em 2000 observou-se, apenas, 1,55% dessa área. Tal fato ocorreu tendo em vista o avanço de práticas agrícolas com predominância da cultura de cana-de-açúcar. A porcentagem de fragmentos florestais em 1971, com áreas menores que 10 ha, era de 46,72%, já em 2000 esse número passou para 78,51%, concluindo-se um processo de fragmentação acentuado (31,79%) no período analisado. Os fragmentos florestais com maior extensão em 1971 se apresentaram extremamente fragmentados em 2000. Aproximadamente 60% dos fragmentos, nas duas épocas, apresentavam forma alongada, indicando alta relação perímetro/área.

The criticism of Cartesian philosophy is correlated on four pillars: the fragmentation of knowledge, the separation between mind and body, the impossibility of the reductionist method for explanation of natural phenomena, and in the superiority of the reason as the only valid form of knowledge. These last two pillars, as many environmentalists claim, contributed decisively to the devaluation of the res extensa over the res cogitans. To check this we used as a theoretical framework the following texts: Discourse on Method, Rules for Conduct of the Spirit and Metaphysical Meditations. By reading these works it was found that the first two pillars (the fragmentation of knowledge and the separation between mind and body) there are no theoretical basis in texts. The failure of the reductionist method to explain the ecological and atomic phenomena and the overcoming of reason as the only valid form of knowledge are supported in their philosophy.

The Creative Economy is an experimental laboratory for the creation , innovation , invention and reinvention of the universe of media - analog and digital . The scenery in the media and converging technologies favors the process of “ creative destruction and destructive creation “ of this field . The mapping of basins and technological corridors distributed through the territory of concentrated areas creates an infrastructural chassis for the production of content , information and entertainment . As locus and logos of immaterial production , digital ecology that gives speed to the flow of production - planning, fundraising , publishing , distribution and enjoyment - and allows the dispossession of their local clusters , the fragmentation and dilution of their creative chains . The collective cultural production and creation appropriating these capilarizados articles and produce content against political, economic and social status quo . The land is fertile and favorable to the emergence of radical media and rebels that recreate the public sphere , and edit poor public spheres , alternative , radical and efficient , the tactical point of view . This article aims to contribute to studies and research that scour the ecosystem of the media for understanding the management of their creative processes, actors and critics of tangible and intangible resources that support their communication actions .

Watersheds are considered important study units when it comes to environmental planning, with regard to the optimal use of water resources. Water scarcity is predicted and feared by many societies, and proves to be an increasingly tangible problem nowadays. Still from the perspective of extreme events, this dissertation considers the study of flood waves in the sub-basin of the stream Claro, which belongs to the Corumbataí watershed. - SP, since thay can also have devastating effects for the population, A Decision Support System for Flood Routing Analysis in Complex Basins, ABC 6 software was applied in order to obtain hydrographs and peak flows in the sub-basin of the stream Claro, for return periods of 10 and 100 years, aiming to comprise events of different magnitudes. The model Soil Conservation Service (SCS) and the triangular SCS hydrograph were adopted for the simulations. Simultaneously, the Kokei Uehara method was applied for the obtainment of peak flow values under the same conditions, seeking to compare results. Data collection was performed using geoprocessing tools. For data entry in ABC 6, the fragmentation of sub-basin of the stream Claro was necessary, which generated 7 small watersheds, in order to fulfill a software demand, as the maximum drainage area it accepts is 50km² for each watershed analyzed. For RT = 10 and 100 years, respectively, the results of peak flow with use of ABC 6 were 46.10 and 95.45 m³/s, while for Kokei Uehara method, the results were 47.17 and 65.26 m³/s. The adoption of a single value of discretization time for all watersheds was indicated as limitation of ABC 6, which interfered in the final results. Kokei method Uehara considered the sub-basin of the stream Claro as a whole, which reduced the error accumulation probability
