Topic : Land use, climate change and resilience in Yamal-Nenets social-ecological system, Arctic Russia Speaker : Prof.Bruce Forbes Prof. Forbes conducts research in applied ecology and geography in permafrost environments encompassing both the natural and social sciences. Abstract:In contrast to northern Alaska and Canada, most terrestrialand aquatic components of West Siberian oil and gas fields are seasonally exploited by migratory herders, hunters, fishers, and domesticated reindeer (Rangifer tarandus L.). Despite anthropogenic fragmentation and transformation of a large proportion of the environment, recent socioeconomic upheaval, and pronounced climate warming, the Yamal-Nenets social-ecological system is highly resilient according to a few key measures. Particularly crucial to success is the unfettered movement of people and animals in space and time, which allows them to alternately avoid or exploit a wide range of natural and anthropogenic habitats. However, expansion of infrastructure, concomitant terrestrial and freshwater ecosystem degradation, climate change, and a massive influx of workers underway present a looming threat to future resilience.
