It is a very important and timely question. I am not a mountain region expert, but I would recommend the work of Prof Kenneth Hewitt from the Department of Geography and Environmental Studies, Wilfrid Laurier University, Canada. You can find a sample of his lifelong work in mountainous regions here: http://rga.revues.org/1653
Very apt question Tek. Ya we people of Mountains for human survival must talk on the issue (which is beyond debate and uni vocal). Adaptation is a must and should be addressed through empirical research.
I perceive this in two ways - At local level and at regional level. The local level includes evaluation of within and between household level adaptation as well as community or village level adaptation. For the empirical evaluation, the parameters at household/community level must includes the decision, social, economic, cultural and institutional environments, however, the regional level should be focused on broader domain such as infrastructure, physical and financial resources as well as human capital role. Based on integration of these two the adaptation plan should be formulated.
