Governando os comuns ou para os comuns?: gestão de áreas protegidas e os arranjos institucionais da política ambiental no Estado de São Paulo

Desde o século XIX, quando foi instituído o primeiro parque nacional, a gestão de áreas protegidas foi evoluindo e se aprimorando, sendo um importante mecanismo para a conservação da biodiversidade e uma das ações de maior intervenção estatal. Neste sentido, esta dissertação apresenta uma análise dos arranjos institucionais da política ambiental que impactam o uso comum dos recursos naturais por populações residentes do Parque Estadual da Serra do Mar. Para esta discussão, são analisados: o embate teórico entre ambientalismo e socioambientalismo; a problemática do uso de acesso comum, associada a necessidade, ou não, de intervenção governamental; os programas e ações do Governo do Estado de São Paulo para a consolidação das unidades de conservação de proteção integral; e as variáveis que compõe os arranjos institucionais da política ambiental dos casos avaliados, na Cota 400 e Água Fria, no município de Cubatão. Face aos arranjos institucionais da política ambiental para gestão de áreas protegidas, esta dissertação busca compreender qual a melhor situação para a conservação dos recursos naturais, com estudos aplicados a luz do modelo proposto por Elinor Ostrom. A análise dos casos permitiu verificar uma performance institucional frágil da comunidade para o uso sustentável dos recursos de acesso comum.

Comunidade fitoplanctônica como discriminador ambiental em açude eutrófico tropical semiárido (Barragem Armando Ribeiro Gonçalves, RN) e divulgação científica para reflexão social

The knowledge of the phytoplankton community, as an integral and dynamic processes of eutrophication, provides information essential for proper management and handling. A growing problem of cyanobacteria in reservoirs around the world as a result of artificial eutrophication processes, generating a particular concern, because some species produce cyanotoxins, which can cause adverse effects on human health. The present work aims to characterize the spatial and temporal dynamics of phytoplankton, assessing their potential as ecological indicator of water quality in reservoirs semiarid region. The samples of water were collected monthly between 2009 and 2011, at three points along the dam Armando Ribeiro Gonçalves / RN. In each sample were measured physico - chemical analysis of water and biological components. We conducted a scientific dissemination activity, with distribution and reading primer on eutrophication, informative talk about water quality, questionnaires and performing a play in a public school in the city of Itajá / RN. The reservoir was considered eutrophic in three points, taking into account the values of chlorophyll -a and phosphorus, adopted to characterize eutrophic environments of semi-arid areas. High density of cyanobacteria, with a maximum value of 2.227.862 cél.ml- 1 and minimum of 43.456 cél.ml- 1 was recorded in lentic and semilêntico points throughout the study, exceeding the levels of drinking water (20.000 cél.ml- 1) established in 2.914/2011 Ordinance of the Ministry of Health of Brazil. All samples contained microcystin, and 44 % had values superiores1μg L- 1. The thermal pattern of the water column showed micro stratifications with differences of less than 1 ° C from five feet deep. The distribution pattern was the type profile clinogrado with oxygen deficit in the bottom of the reservoir. Oxiclina from 10 meters depth was observed during the rainy season (May-June) in the two years of study. The phytoplankton community was represented by 10 functional groups: S1, M, H1, Lo, P, F, Sn, P, W2 and R. The assessment of the ecological status of the system by the index Q showed poor water quality. The results of the study show that the vertical variations were less pronounced than the seasonal variations of cyanobacteria and phytoplankton community in general in the reservoir. The presence of cyanotoxins confirms the need for the monitoring of water quality and measures to reduce eutrophication in water supply reservoirs semiarid RN and demonstrates the challenge for water managers and health authorities to ensure water quality and consequently minimize risks to human health. Compared to the lecture, the primer was considered more efficient in sensitizing the participants, featuring a dynamic practice, differentiated learning, create opportunities for students to rethink attitudes of respect and care for the environment, and shall have the opportunity to learn the subject content from your reality and living environment. The knowledge generated from the activity of scientific were seen as essential for raising awareness of some of the region`s environmental problems , such as eutrophication
