No Rio Grande do Sul mais da metade das 23 Unidades de Conservação (UC) estaduais são Parques, categoria que privilegia o uso público. O Programa de Uso Público visa ordenar a presença humana no interior da UC, prevendo turismo, educação e interpretação ambiental. Este trabalho teve por objetivo diagnosticar a realidade dos programas de uso público dos parques estaduais do Rio Grande do Sul, conhecendo a percepção dos gestores dessas áreas quanto às atividades desenvolvidas e a eficácia de cada programa. Oito parques estaduais que já contam com plano de manejo foram estudados. A falta de funcionários é apontada por todos os gestores como sendo o fator responsável pelo fato de sete parques estaduais não receberem visitantes. Mais ...

Observação de aves tornou-se um segmento do turismo de natureza, constituindo um mercado especializado. No Brasil, o “birdwatching” atrai turistas para mais de 50 destinos. Hoje existe em torno de 37 mil observadores de aves no Brasil e a atividade tem crescido exponencialmente. Estima-se que nos últimos dez anos houve um incremento de 1.650% neste número e a maioria dos observadores está vinculada à plataforma colaborativa WikiAves. O Brasil figura entre um dos mais importantes destinos para quem quer praticar a observação de aves. Neste estudo foi investigado se os observadores de aves reúnem perfil socioeconômico capaz de alavancar uma cadeia de ecoturismo no litoral médio do Rio Grande do Sul, onde se localiza o Parque Nacional da Lagoa do Peixe. A pesquisa verificou qual o peso econômico que o turismo de “...

No Rio Grande do Sul, 607 espécies vegetais estão em risco de extinção. Somente as arbóreo-arbustivas ameaçadas chegam a 103 espécies. Diante desse quadro, outras estratégias além das áreas protegidas devem ser pensadas com vistas a atender aos interesses da conservação de espécies ameaçadas. A conservação ex-situ, inclusive em espaços urbanos vem sendo discutida. A partir da lista das espécies da flora ameaçadas de extinção no Rio Grande do Sul foram selecionadas as espécies arbóreoarbustivas categorizadas como “Criticamente em Perigo”. Revisamos as informações disponíveis para cada uma das espécies quanto aos aspectos biológicos com o propósito de incentivar o emprego destas espécies em projetos paisagísticos n...

The Brazilian environmental licensing process was legally established in 1986. It provides for 3-phase licensing: pre-license, installation license and operating license. The environmental licensing is triggered by the environmental license application with the Environment Impact Assessment (EIA) authority. Depending on the regional location of the project or its polluting potential, the licensing may be conducted by the federal, state or local environmental agency, which makes the screening based on legislation to determine whether or not the environmental license requires an environmental impact study. There is a rule that defines those activities that will necessarily have to elaborate the EIA. After screening, the environmental agency establishes the Term of Reference. There is no scoping process in Brazilian law. Consequently, most environmental-impact studies lack a focus on core issues ...

Due to the ongoing process of habitat loss and degradation, the management of private lands for wildlife and other alternative conservation strategies can be important elements in a system of biodiversity conservation. In Rio Grande do Sul, landowners and hunters manage rice fields and seminatural wetlands for hunting purposes, whose contribution for the protection of wetlands and wetland species has not yet been evaluated. In this paper we (1) describe the main management actions in agricultural lands of the Coastal Zone of Rio Grande do Sul for duck hunting purposes; (2) characterise the semi-natural areas selected by hunters; and (3) analyse the trends of hunting participation on the State. Rice fields were selected as hunting areas by 70% of hunters and semi-natural wetlands by 65% and these proportions didn’t change between 2002 and previous years (χ2 = 1,723; p>0,5). About 27% of the hunting areas are managed to attract waterbirds. The most frequent practices are water level regulation (N=48), supplementary feeding/baiting (N=37) and control against illegal hunters (N=10). Land leasing or informal agreements were practised by 12% of hunters in order to guarantee and control access to private lands. Semi-natural areas selected by hunters have greater richness and abundance of game waterbirds than non-hunted areas. The number of hunters declined 93.5% between 1974 and 2005. In the same period, the number of species allowed for hunting and the weekly bag limits also decreased steadily. The predisposition for the management of private lands both by hunters and landowners can be an opportunity to foster the capacity of agricultural landscapes to protect wetlands and wetland biodiversity, reducing the conflicts with economic and leisure activities. Otherwise, the declining trend in hunting participation suggests that less private areas are been managed for waterbirds. Novel strategies are needed to foster the conservation of wetlands and wetland species outside the system of protected areas and a sound leisure hunting system can help on this task. Key words: recreational hunting, wetland birds, anatidae, management, marshes, natural renewable resources.

Nevertheless, little attention has been given to their management, in the form of clearly established buffer zones (BZ). Moreover, a great deal of confusion exists around their objectives, dimension and location. In this study we review the scientific and technical literature on BZ planning and the related legislation of Argentina, Brazil, Paraguay and Uruguay. Current literature emphasizes the threats to biodiversity from the lands around protected areas, and their role to promote life quality of neighboring communities. On the other hand, neglect the negative impacts of protected areas on the use of land around them, and the potential role of these lands in supplementing or complementing the protection of species and habitats. In the countries which legislation we surveyed, the BZ guidelines are superficial and confusing. The reviewed literature does not present an applied guide for the implementation of BZ. The lack of a comprehensive perception of the relationship between protected areas and their surroundings, clear objectives for buffer zones, and scientific rules for delimitation precludes the integration of these key areas in the effort to conserve biodiversity.
