The dissertation aims at developing means to integrate conservation and development in biosphere reserves in Madagascar. Despite a multitude of concepts such as UNESCO biosphere reserves, Integrated Conservation and Development Projects and community-based natural resource management, gaps between conservation and development remain to exist. In a qualitative case study in Mananara-Nord and Sahamalaza Iles-Radama Biosphere Reserves in Madagascar data was collected on biosphere reserve management, local use of natural resources and socio-cultural aspects that influence natural resource use. Furthermore, natural values local people associate with the forest were investigated. Analysis revealed that management capacities constitute a limiting factor in biosphere reserve management. Collaboration between management, local people and international organisations fosters the achievement of both conservation and development. However, collaboration is only possible if (i) clear rules are formulated and (ii) partners have a vision in common. Based on the theory of social capital, newly introduced and locally existent rules/institutions having an influence on the use of natural resource were categorized in bonding, linking and bridging social capital. Furthermore, the perception of natural values was classified in instrumental and non-instrumental values and assigned to ecosystem services identifying the importance of nature for human well-being. With the capabilities approach Amartya Sen defined human well-being as the achievement of those capabilities a person considers valuable. This includes aspects that assure livelihoods on the one hand and aspects that are conducive to well-being on the other, thus both being relevant for development. In the dissertation capabilities are based on both instrumental and non-instrumental natural values and consequently offer an opportunity to demonstrate and characterise the relationship between nature and human well-being. Social and natural values provide orientation for a biosphere reserve management. The category bonding social capital (social values) describes local socio-cultural aspects in communities and their importance for collaborative processes. Natural values provide the management with guiding principles to foster nature conservation and to integrate locally existent capabilities. Supporting and furthering these capabilities enables the development of new capabilities of all concerned persons. The dissertation demonstrates various possibilities to build bridges between (i) nature conservation and development, (ii) natural and social sciences, (iii) formal regulations and local socio-cultural aspects and (iv) diverse actors. Implementation of a social monitoring is recommended together with local stewards and Malagasy students to collect information about the perception of natural and social values and use them as guiding principles for biosphere reserves. Collaboration with national and international scientific institutions can foster this process.
