<p>Himalaya presents a great range of lifestyle and livelihood base to its native communities. The extreme climatic condition imposes a restriction on the living conditions, local ownership, alternative sources of income, women's empowerment, and long-term sustainable livelihoods are main elements of community work. But improvements in communication and transportation system have improved the lifestyle of the people living in those regions. The breadth of natural biodiversity in the Himalayas is complemented by a rich mosaic of cultures, traditions and people. But the ethnic groups living in remote valleys of the Himalayan region have generally conserved their traditional cultural identities. Ancient traditions and livelihoods of many communities remain woven into the balanced use of natural resources. They depend on these resources for their livelihoods, and value ecosystem services such as freshwater, erosion control, and agricultural and subsistence harvests.</p><p>Forests are strained as demand continues to grow for timber and food crops.<em> </em><em>Himalaya’s communities have suffered a disastrous slump in production due to erratic weather in recent years, but the government is helping out with various insurance and relief scheme.</em> For such remotely located communities of this part of Himalaya agriculture, nomadic herding, hunting and gathering are the main activities of the people who are unable to fulfil their basic requirements. The present paper investigates factors that have brought about physical and socio-economic changes in various parts of Indian region of Himalayas, interlinked with the fragile Himalayan environment by mapping, monitoring and change analysis with the help of remote sensing and GIS techniques.</p>

Thermokarst (Thaw) lakes are landforms found in topographic depressions created by thawing ground ice in permafrost zones. They play an important role in the regulation of climatic functions. These lakes are a manifestation of warming surface temperatures that accelerates the ice-rich permafrost to degrade by creating marshy hollows/ponds. In the current global warming scenario, the thermokarst lakes in the high mountain regions (Himalaya) are expected to grow further. This accelerate permafrost thawing which will affect the carbon cycle, hydrology and local ecosystems. This phenomenon has attracted huge scientific attention because it has led to a rapid mass change of glaciers in the region, including extensive changes occurring on peri-glacial environments. The most striking fact is the release of an enormous amount of greenhouse gases, including methane, carbon dioxide and nitrous oxide that is locked in these lakes. The present study delves into the thermokarst lakes in the upper reaches of Chandra Valley and Western Himalaya. The study also aims at designating the impact of their changes on the ecosystem, particularly their influence on the atmospheric greenhouse gas concentrations.
