What are the impacts of activities undertaken in UNESCO biosphere reserves on socio-economic wellbeing in Southeast Asia? A systematic review.

With 727 BRs worldwide, the BR model has been accepted and developed as an approach to facilitate the implementation of the UN's SDGs. However, our work shows that interventions implemented in UNESCO BRs can bring about impacts in quite diverse ways: positive, negative, unchanged, and may often present both positive and negative impacts in the same situation. This reconfirms that the expected win-win outcomes of UNESCO BR model in terms of biodiversity and socio-economic development should be more carefully considered. We suggest some main points for consideration, particularly when developing management mechanisms for UNESCO biosphere reserves and/or managing activities in biosphere reserves. We also highlight the need for further research to explore the socio-economic impacts of the UNESCO biosphere reserves in Southeast Asia, especially on the domains of freedom of choice and action, security and safety, and culture and spirituality. Moreover, it is vital to have research projects that measure long-term impacts of biosphere reserves, which have been lacking in previous work. Finally, the potential impact of external factors should be considered in programme and monitoring design.
