Using Ostrom's principles to assess institutional dynamics of conservation: Lessons from a marine protected area in Brazil

Abstract

The success of protected areas as a management tool for biodiversity conservation remains as a challenge, and broader approaches for protected area management have been proposed. Considering biodiversity conservation as an issue of the commons and within the realm of social-ecological systems is a promising alternative. In Brazil protected areas are under a State management regime, ruled by the National System of Conservation Units. The Ecological Station of Guaraqueçaba (ESG) is a no-take protected area located in the Paranagua Estuarine Complex, surrounded by traditional communities. In this article, Ostrom's design principles were adapted to assess the institutional dynamics of this protected area management, during two periods. Research methods included semi-structured interviews, participant observation and document analysis. During the first period, management actions were oriented to prevent the conversion of forest areas into anthropic occupations. The second period originated in 2000 with the creation of the National System of Conservation Units, which established more precise management tools and mechanisms for participatory decision making. In both periods there was low fulfillment of Ostrom's principles. The main changes over time were the creation of the ESG management council as a conflict-resolution mechanism, and an increase in the recognition of the rights of local communities. Yet, only three of the eight principles are totally present in the current institutional arrangement (well-defined boundaries, conflict-resolution mechanisms, and minimal recognition of rights). The results suggest a not robust institutional arrangement in terms of commons sustainable management.
