| Title | Climate change impact on biodiversity and its implications for protected areas management: Case study of Dashtidjum Zakaznik, Tajikistan |
| Summary | Climate change is an unequivocal global problem that has many negative consequences and can become the dominant direct driver for the loss of biodiversity. Its impacts on species and ecosystems have already been observed worldwide and vary from species phenological changes, to shifts in their geographical distribution and to extinction. Species adaptive responses, in turn, pose various challenges for adequate management of protected areas that play a key role in biodiversity conservation, and require review of conservation goals and implementation of adaptation measures. This thesis focuses on Tajikistan as a mountainous country with unique biodiversity, and explores climate change impacts on the biodiversity of one of the most vulnerable reserves rich in biodiversity – Dashtidjum Zakaznik. The current and potential impacts of climate change on the biodiversity of the zakaznik have been analyzed following the DPSIR approach and based on up-to-date knowledge, experts’ assumptions and observations. An analysis of meteorological data has confirmed an increase of mean temperatures and anomalies in precipitation. The main factors of climate change impacts, as well as species vulnerability and adaptive responses, have been identified for the main taxa of flora and fauna, with a focus on rare and endangered species, and all represented ecosystems. A vulnerability assessment has shown potential population decline for the majority of species important for conservation, migration of some species northwards outside the area of the zakaznik, extinctions of some species and increases in population sizes for other species, mainly invasive species. An assessment of national policies and strategies has identified a number of prerequisites for the implementation of adaptation measures that may contribute to the mitigation of the climate change impacts on the biodiversity of Dashtidjum Zakaznik. They include expansion of the protected area, and establishment of buffer zones and migration corridors. |
