| Project Brief Description: | Little is known in detail about the vulnerability of mountain ecosystems to climate change. Intuitively it seems plausible that these regions, where small changes in temperature can turn ice and snow to water, and where extreme slopes lead to rapid changes in climatic zones over small distances, will show marked impacts in terms of biodiversity, water availability, agriculture, and hazards, and that this will have an impact on general human well-being. However, the nature of the mountains, fragile and poorly accessible landscapes with sparsely scattered settlements and poor infrastructure, means that research and assessment are least just, where they are needed most. And this is true of all for the eastern Himalayas, with the highest mountains in the world, situated in developing and least developed countries with few resources for meeting the challenges of developing the detailed scientific knowledge needed to assess the current situation and likely impacts of climate change on local communities and different ecosystems. This is one of the focal point of this study. Sikkim being a Himalayan state of India is one of the glacier rich areas of India. The state of Sikkim within the Indian Himalayan region (IHR) falls almost entirely in the catchment of the River Teesta. Its rugged and steep mountain topography ranges from 300 to 8598 m above sea level (a.s.l.). Teesta is a flashy mountain river and carries boulders and considerable amount of silt in monsoon month. The river flows in very steep gradient of 1 in 20 up to confluence with Lachung and Chungthang. The catchment of Teesta river basin is characterized by steep to very steep slopes. It is also important to highlight here that of all the Himalayan Rivers, Teesta reportedly has the highest sediment yield. According to Centre for Science and Environment (CSE) (1991), it approximately, brings down 98 cum of silt per hectare of its catchment per year giving an annual denudation rate of 9.8 mm per year. And surprisingly, this is among the highest denudation rates estimated for any river valley in the world. One of the key runoff characteristics of the monsoon dominated •Himalayan catchment• is that the glaciers melt and monsoon peaks coincides (Thayyen and Gergan, 2010). Combined mobilisation of sediment by glacier and monsoon rains in the river during peak runoff period also poses serious challenges in reservoir operation. Understanding the suspended sediment dynamics and sediment status in the basin is one of the core aspects of this proposal for suggesting appropriate measures for maintaining watershed health to enhance watershed dependent ecosystem services. Hydrological variability caused by climate change will greatly affect the livelihoods of people in the region. Rising temperatures and erratic weather patterns have been observed in the last few decades in the Eastern Himalayan region and this trend is likely to continue. Due to increase in glaciers, there are chances of increase in the size of glacial lakes. Therefore, study of glacial lake outburst flood is required to take necessary actions in downstream areas. | |||
