Answer 1

Answer:

Mountains are remarkably diverse and globally important as centers of biological diversity. Mountains' greatest values may be as sources of all the world's major rivers, and those of the Himalayas are no less important in terms of provisioning the ecosystem services that has thus far sustained huge population of people and high levels of biodiversity. The survival of these ecosystems and wildlife sustained are now threatened by human activities like timber harvesting, intensive grazing by livestock and agricultural expansion into forestlands, and above all climate change. This paper presents our findings in the Eastern Himalayas that have reconfirmed earlier studies that temperature will continue to rise and rainfall patterns will be more variable projecting both localized increases and decreases. However, the magnitude of climate change is predicted to be greater for the Eastern Himalayan region than that projected by IPCC for the Asia region. People have perceived changes taking place within their environment and have responded to such changes although the tenor differed. However, people's perceptions are limited to human memory and blur the distinction between climate variability and climate change. The altitudinal shift in vegetation belts is expected to be around 80m-200m per decade with greater shifts at the higher altitudes since the rate of warming increases with altitude. Glaciers, snowfields, and high-altitude ecosystems with biodiversity therein will the most impacted by climate change. At present, there is limited and imprecise knowledge with scientific evidence on how climate change affects biodiversity and human wellbeing. However, the impact is going to be severe as people have limited adaptive capacity considering the economic, socio-political and technological shortcomings in the region. There is a need of consistent data generation for which landscape and transect approaches are conceived by ICIMOD for bridging the gap in medium- and long-term timescale.
