Mountains as Iconic Sentinels of Global Change: A Global Mountain Synthesis and a Case Study from the Tibetan Plateau

Abstract
Mountains are globally ubiquitous yet locally unique and are far more than just lands at high elevation. I will present a conceptual model, based on 18 mountain case studies worldwide, that identifies a suite of mountain-specific characteristics and persistent incongruities that require a new approach to understanding mountain sustainability.  Serving as an example of a tightly coupled social-ecological mountain system, I will present select results from an interdisciplinary study of herder and ecosystem vulnerability to climate warming, extreme weather events (‘snow disasters’) and grazing policy in central Tibet.  A multi-factor ecological experiment combined with landscape sampling reveals that yak grazing promotes the growth of Kobresia pygmaea, the dominant plant species and preferred forage, and promotes soil C storage and carbon uptake, while experimental warming leads to soil moisture stress, decreased K. pygmaea, and increased shrubs, thus decreasing forage quality and soil C storage.  Local knowledge of climate and ecological change supports the finding of a warming-induced delay in vegetative green-up in Tibet, a finding that has been subject to vigorous debate. On-going policies have shifted herders’ strategies for coping with ‘snow disasters’ from internal to external and increased their reliance upon the state.  Taken together, these findings suggest that: 1) Tibetan ecosystems are vulnerable to climate warming, with negative implications for livelihoods and ecosystem services; 2) current policies, such as grazing restrictions, are not the solution to rangeland degradation, and are negatively impacting herders and their ability to cope with climate change; and 3) local knowledge is key to adaptation and can help understand on-going ecosystem dynamics.  I will conclude my talk by discussing an on-going initiative to develop a global, transdisciplinary mountain network.
