| Summary: | Although biological corridors have been used to facilitate the movement of wildlife since the
first half of the last century, they have only been officially integrated into conservation
planning at the landscape level in recent years. Supported by the theory of island
biogeography, the principles of metapopulation, and empirical studies, biological corridors
have now been considered an integral component of the conservation landscape to protect
species from local extinction. However, to successfully design these corridors, detailed data
on biology, especially migration behaviors and habitat suitability, should be collected and
analyzed. This is a critical challenge for conservation planners, particularly in the context of
climate change because it will result in range shifts of many species. In Vietnam, this task is
even more difficult as climate change is going to have serious effects on the socio-economic
situation, land-use patterns, and human migration rates from lowland to upland regions. To
help resolve these complex problems, it is essential to develop novel approaches, which can
take into account the socio-economic and physical variables, in order to find optimal solutions for conservation planning, including maintaining landscape connectivity. To clarify the roles of biological corridors in biodiversity conservation, we examine some concepts and definitions, provide some good practices and lessons from other countries, and review the status of corridor projects in the region, including Vietnam. We conclude the paper by discussing new technological advances, which can help provide potential solutions for problems in designing a network of protected areas and biological corridors in the context of climate change in Vietnam. |
