This article seeks to contribute to the debate on the importance of cultural collective producers of anti-capitalist content, ownership of digital ecology by subaltern segments, the creation of the opposition media to exclusionary globalization and the articulation of alternative and radical public sphere for the recent demonstrations policies in planetary scale. Data were collected in the first half of 2013, on a course completion project in vehicles with citizen journalism characteristics ["Portal Fórum", "Outras Palavras" and "Observatório da Imprensa"]. Partial these mapping results indicate that these manifestations inherited anti-capitalist demands of previous decades, and amplified in [by digitally pathways] in political demonstrations that swept those abrasive months in major cities worldwide.

Aplicação de análise multicriterial para determinação de áreas prioritárias à recomposição florestal

Using the Geographic Information System (GIS) and taking into account its capability to analyze spatial data, a database of updated spatial data from the sub-basin of the Descalvado stream, Botucatu, SP, was developed to provide an evaluation and diagnosis of the area concerning land use and the degradation processes therein. Through GIS, priority areas for forest recovery were defined by Multicriteria Evaluation and using the Ordered Weighted Average method. The latter allows the decision maker to define the area to be recovered, facing limitation of resources, among one of the proposed scenarios, or do it in stages. The study showed that there are accelerated erosion processes in the headwaters of the springs of water bodies; there is also fragmentation of native vegetation, especially in hillside areas, and little presence of native vegetation in riparian areas. The application of the multicriteria analysis using the Ordered Weighted Average was important as it systematized and discriminated scenarios of priority for forest recovery.

The Pardo River Basin represents the situation of disorderly process of use and occupation of land, where forest fragmentation is one of the results. This study evaluated the use of Multicriteria Evaluation in a GIS, specifically through method Weighted Linear Combination, the generation of map of priority areas for forest restoration in the initial part of Rio Pardo Basin, SP, aiming the conservation of water resources. It can be concluded that, the Multicriteria Evaluation in a GIS is appropriate to the mapping of priority areas for forest restoration. The map of suitability for forest recovery may be useful in the environment planning, providing public and environmental agents making decision, based on a method that takes into account the landscape as a whole and the priority is the conservation of water resources.

The State Forest Edmundo Navarro de Andrade (FEENA), Rio Claro/SP has a huge potential for cyclists tracks; the Unit already have a trail at the principal entrance, passing by firebreaks bordering the towers quadrants and finishing at the municipal road. This work aims the ambiental interpretation of this trail already established and implant activities planned before at the public use program of the State Forest according to the management plan of the Unit; to interpret the tracks for mountain bike cyclists; promote the conservation of natural, historic and cultural resources of the Forest. At the present work has been accomplished the Ambiental Interpretation through the panels, containing the characteristic native flora and fauna, the existing water resources at the Unit and also the representatives individuals of the exotic arboreal species, found around the trail. Ten points were chosen for interpretation, therefore, for preparation of the script it was considered besides the bibliographic literature, experiences of project team members at FEENA, Unit Management Plan knowledge relating the gaps in the public use program and field work. The panels contain figures and texts about the chosen topics, to promote a language easily understandable to the visitor and concomitantly, inform to the population who attends the Unit, increasing this way the user satisfaction
