This contribution forms part of the framework of the CasoNatura research project in order to analyse the social trust in two protected natural areas of Castilla-La Mancha region (Spain). It aims to assess contexts of legitimacy for the Government and management of the space between the agents and institutions. Furthermore, it tries to detect the level of territorial identity which has the population with regard to their municipality, natural space and supra-local scales. Conflict detection of environmental, social and economic nature and how to manage them will be analysed and assessed through methodologies including both bibliographical and documentary sources and qualitative techniques of socio-territorial analysis: surveys of the local population and Governing Board of the Park, interviews with "qualified informants" and interviews with organisations/institutions located in the territory in question.

It is widely accepted that biodiversity loss and poverty are linked problems and that conservation and poverty reduction should be tackled together. However, success with integrated strategies is elusive. There is sharp debate about the social impacts of conservation programs and the success of community-based approaches to conservation. Clear conceptual frameworks are needed if policies in these two areas are to be combined. We review the links between poverty alleviation and biodiversity conservation and present a conceptual typology of these relationships.
