A Política Nacional do Meio Ambiente tem como objetivo a conciliação do desenvolvimento econômico e social com a qualidade ambiental, e dispõe de vários instrumentos que procuram contemplara capacidade de suporte do meio. Assim, a discussão sobre a localização das atividades é uma etapa importante para a avaliação da viabilidade ambiental de um determinado empreendimento, notadamente em processos de licenciamento ambiental. O trabalho apresenta uma abordagem metodológica para integração de critérios técnicos, ambientais e sociais em estudos de alternativas de localização de aterros sanitários, com especial atenção à interação entre os aspectos ambientais e os elementos fundamentais de um projeto (a saber, requisitos locacionais e concepção tecnológica), aplicado em um estudo de caso em São Carlos (SP). Como resultados principais, destacam-se o maior foco nos impactos significativos e a possibilidade de envolvimento de segmentos importantes da sociedade previamente à elaboração dos estudos ambientais.

In recent years the concept of "Land Stewardship" has gained a great importance. In short, it means that local entities and individuals can protect enclave of high ecological and cultural value. This vision has been effective in some places in the world with success. For example, the “Projeto Sempre Viva”, created in the town of Mucugê, a place located in one of Brazil´s most renowned Natural Protected Areas: the Chapada Diamantina (State of Bahia). We had looked over the available information about this project on the Internet, as well as a personal visit that was made to the site to know it and to have the possibility to talk to their managers. On this basis, it has been reached to the conclusion that this project, born to protect a Sempre Viva´s endemic species in danger of extinction, has turned into an important site for tourism and environmental education, completed with the preservation of the cultural identity of this region which is linked to diamond mining.

Spatial-temporal dynamics of zooplankton in the Caravelas river estuary (Bahia, Brazil). The survey was conducted in order to describe the zooplankton community of the estuary Caravelas (Bahia, Brazil), to quantify and relate the patterns of horizontal and vertical transport with the type of tide (neap and spring) and tidal phase (flood and ebb). Zooplankton samples were collected with the aid of a suction pump (300L), filtered in plankton nets (300μm) and fixed in saline formalin 4%. Samples were collected at a fixed point (A1), near the mouth of the estuary, with samples taken at neap tides and spring tides during the dry and rainy seasons. Samples were collected for 13 hours, at intervals of 1 hour in 3 depths: surface, middle and bottom. Simultaneous collection of biological, we measured the current velocity, temperature and salinity of the water through CTD. In the laboratory, samples were selected for analysis in estereomicroscope, with 25 groups identified, with Copepoda getting the highest number of species. The 168 samples obtained from temporal samples were subsampled and processed on equipment ZooScan, with the aid of software ZooProcess at the end were generated 458.997 vingnettes. 8 taxa were identified automatically, with 16 classified as a semi-automatic. The group Copepoda, despite the limited taxonomic refinement ZooScan, obtained 2 genera and 1 species identified automatically. Among the seasons dry and wet groups Brachyura (zoea), Chaetognatha, and the Calanoid copepods (others), Temora spp., Oithona spp. and Euterpina acutifrons were those who had higher frequency of occurrence, appearing in more than 70% of the samples. Copepoda group showed the largest percentage of relative abundance in both seasons. There was no seasonal variation of total zooplankton, with an average density of 7826±4219 org.m-3 in the dry season, and 7959±3675 org.m-3 in the rainy season, neither between the types and phases of the tides, but seasonal differences were significant recorded for the main zooplankton groups. Vertical stratification was seen for the major zooplankton groups (Brachyura, Chaetognatha, Calanoida (other), Oithona spp, Temora spp. e Euterpina acutifrons). The scale of this stratification varied with the type (square or tide) and tidal phase (flood or ebb). The instantaneous transport was more influenced by current velocity, with higher values observed in spring tides to the total zooplankton, however, there was a variation of this pattern depending on the zooplankton group. According to the data import and export of total zooplankton, the outflow of organisms of the estuary was higher than the input. The results suggest that the estuary of Caravelas may influence the dynamics of organic matter to the adjacent coast, with possible consequences in National Marine Park of Abrolhos

Este artículo analiza las políticas ambientales, relacionadas directamente con el establecimiento y el manejo de los espacios protegidos, y muy especialmente, con las zonas de amortiguamiento en Costa Rica, como un elemento esencial para comprender la dinámica en áreas de conservación reciente creación, por ejemplo el Parque Nacional Piedras Blancas y la Reserva de Vida Silvestre Golfito. Se analiza en esta área, de forma cualitativa, los procesos socioambientales, como componentes fundamentales en la determinación del nivel de alcance de la conservación de estas áreas protegidas. Finalmente, este artículo concluye la importancia de abordar la gestión de los espacios protegidos desde perspectivas sistemáticas, que permita no sólo articular diferentes áreas, sino que realice una gestión que considere tanto los aspectos socioeconómicos para la conservación como los ecológicos, debido a que las condiciones de pobreza imperantes en el área de estudio han limitado fuertemente la consolidación de estas áreas. Abstracts:This article analyzes the environmental policies related directly with the creation and management of protected areas, especially the buffer zones in Costa Rica, as crucial elements in the comprehension of different dynamics in the recently created conservation areas, like the Piedras Blancas National Park and the Golfito Wildlife Refuge. There is a qualitative analysis regarding the socio-environmental processes, as key elements in determining the conservation level in these protected areas. Finally, the article details the importance of approaching the management of protected areas from systematic points of view that allow the articulation of different areas, as well as considering the basic and socioeconomic aspects of the area, due to the fact that critic poverty conditions have strongly limited the consolidation of these protected areas.

O potencial turístico de um lugar deve-se, sobretudo, aos seus aspectos paisagísticos, sendo viável a prática do ecoturismo sustentável. O Estado do Maranhão apresenta diversos ecossistemas dentre os quais se encontram: áreas de floresta com característica amazônica, cerrado, campos inundáveis, manguezais, praias e sistema de dunas. A área de estudo é o município de Santo Amaro do Maranhão que se situa na Mesorregião Norte Maranhense e Microrregião dos Lençóis Maranhenses, compreendendo a área do Parque Nacional dos Lençóis Maranhenses. O objetivo deste trabalho é analisar os elementos naturais que proporcionam a condição de pólo turístico regional para a cidade. A zona dos Lençóis Maranhenses é composta por superfícies formadas de depósitos eólicos e aluviões marinhas, de idade Quaternária. O desenvolvimento da pesquisa foi pautado nos métodos dedutivo, que subsidiou as pesquisas de gabinete, e o método indutivo, utilizado como base na observação da paisagem e dos fenômenos locais, auxiliado pelo método fenomenológico e em na realização do trabalho foram adotados como procedimentos metodológicos: levantamento e análise da bibliografia, atividades de campo envolvendo reconhecimento, registro fotográfico, mensuração de dados e realização de entrevistas com os moradores. Os resultados indicam que o turismo acarreta impactos ambientais negativos, representados pelo uso indevido do rio Alegre, dos lagos e dos campos de dunas. Na sede do município, o crescimento das construções civis em locais impróprios atrelados a especulação imobiliária, torna essencial a intervenção do poder público com políticas de desenvolvimento do turismo sustentável como instrumento de melhoria das condições de vida da população sem prejudicar, de forma significante, o meio natural.
