The Designation of Protected Areas (PAs) is the most important policy internationally for the protection of biodiversity. At international level, approximately 15.4% of terrestrial and inland water areas and 10% of coastal waters consist of PAs. The importance of protected areas as a biodiversity conservation strategy will be further strengthened in the immediate future given that the aim is to protect at least 17 per cent of terrestrial and inland water, and 10 per cent of coastal and marine areas in the world by 2020. Designating new PAs and expanding current ones across the world will contribute to the achievement of biodiversity conservation and sustainable development targets. However, conservation policies also need to consider issues of social justice, especially for local communities living near protected natural resources. Finding a balance between biodiversity conservation targets and sustainable development goals for local communities is a major challenge. This is because the establishment of PAs implies significant impacts for local communities which, in turn, determine the level of efficiency of the protected area. The importance of social impacts is increasingly recognised in the literature as there is a need to better understand the distribution of PAs’ costs and benefits and to strike a balance between environmental protection and the social, economic and cultural implications of PAs.
Although studies measuring social impacts of PAs have significantly increased, understanding their variation, both at individual and community level, remains under-explored. Currently no framework exists explaining how perceptions of social impacts are formulated in micro and macro level and also how they change through time. The identification of specific parameters influencing these perceptions is a challenging but very important task which will assist in planning effective PAs. Theories from the fields of human ecology, environmental sociology and psychology provide significant evidence regarding micro and macro level factors which can explain perceptions of social impacts and the level of public acceptability for such initiatives.
