Das Projekt "Arctic biodiversity and indigenous people of Eastern Siberia in a changing climate" wird vom Umweltbundesamt gefördert und von Universität Zürich, Geographisches Institut durchgeführt. Global warming, occurred from the 2nd half of the 20th century, has already intensively influenced on the Earths biota (Climate change, 2005). The average temperature of the planets surface, expected to rise further, will impact more on biological processes in the biosphere in particular and on the ecological situation of the whole planet. Climate change is expected to affect not only biological processes, but also every sector of society. In the short-run some of these impacts could be profitable, however in the longer term most of the effects could be harmful to local communities and society as a whole. Arctic regions are sensitive to climatic change because global warming is mostly noticeable at high latitudes, and Arctic processes are particularly vulnerable to effects of temperature (Chapin et al, 2009). This investigation is planned to be carried out in the Arctic regions of Eastern Siberia, Russia. Arctic indigenous people are dependent on subsistent harvesting. And changes in environment may cause severe changes to their livelihood. Therefore it is vital to conduct this investigation to get insights about subsistence practices of the Arctic inhabitants, the relation of the indigenous population to the environment and changes referred to global warming in the region.
