3 UNESCO Biosphere Reserves

UNESCO Biosphere Reserves are designated areas where sustainable development and biodiversity conservation are promoted and integrated. These reserves often serve as “islands” of protected natural and cultural landscapes within larger, more developed regions. In this sense, the term “metaphoric island” could be used to describe the idea that within the biosphere reserve, ecosystems are somewhat isolated from the pressures of urbanization and resource exploitation found in the surrounding areas.

This isolation in terms of conservation goals and sustainable practices can be seen as a way to protect and preserve unique natural and cultural resources. However, it’s important to note that this is a metaphorical use of the term “island,” and UNESCO Biosphere Reserves themselves are not necessarily islands in the traditional geographic sense.  They are not a literal islands but designations for a specific type of protected area that encompasses terrestrial, marine, and coastal ecosystems. While it is not a physical island, the term “metaphoric island” could be used in a conceptual or symbolic sense to describe the isolation and conservation goals of a biosphere reserve.
