Watershed Issues And Policies Of The Himalayan Region

Sharon Fighter Final Paper Watershed Issues and Policies in the Himalayan Region The Himalayan region provides water to more than 150 million people in the uplands and lowlands, and the water basins support 1.5 billion people who inhabit the area, and up to 3 billion people rely on the food and energy produced using the Himalayan watershed (1). The glaciers in the Himalayas deliver large quantities of runoff to the major tributaries of the Ganges and the rivers in the adjacent basins (2). These glacial resources are essential to the water supply both in the uplands and lowlands for irrigation, hydroelectric power and agriculture and household use. The flows of the Himalayan watershed are affected by the precipitation and the melting of snow and ice from the glaciers. The runoff of melting snow and ice in recent years suggests that climate change may be having a significant impact on flows in the watershed, reducing the amount of runoff in addition to the decline in monsoon rainfall since the 1960’s (2). Inadequate water supplies and energy shortages are causing serious problems in all the surrounding countries that these rivers serve. They threaten domestic stability, leading some of the countries to build dams to control the flow of water and to generate hydroelectric power (3). In the uplands, China has an increasing demand for hydro-electric power, but water scarcity of the rivers is causing tension in the Himalayan watershed and international tension is created alongShow MoreRelatedWater Is Essential For Meeting Human Needs1022 Words   |  5 Pagesstoring the excess run-off, the average production of rice can be raised to 120 million tonnes and that of wheat to 70 million tonnes within the next 5 to 10 years. Many eminent intellectuals are in the view that the third world war would happen on the issue of water. One of the most crucial factors affecting development, is the management of water resources. Water is the essential for sustainability. Day to day there is an increase in demand for water resource due to population growth and it is essentialRead MoreClimate Change And Agriculture On Indi Impacts And Adaptation For Sustainable Future1646 Words   |  7 Pagestheir livelihood. Agriculture, along with fisheries and forestry, contributes 16.11 % to the Indian Gross Domestic Product (GDP). Therefore India has concern about climate change issues because of its large population who depends upon climate sensitive activity like agriculture for their livelihood, water storage in the Himalayan glaciers which are the source of major rivers and groundwater recharge. Possible changes in temperature, precipitation and CO2 concentration are expected to significantly impactRead MoreWater as a Sour ce of Future Conflict in Sa26984 Words   |  108 Pagesbillion people† already lack water supplies. Water use has risen six-fold over the past 70 years. By 2050, it is estimated that 4.2 billion people live in countries that cannot meet people’s daily basis needs.

DISADVANTAGES: †¢ Environmental issues The ecological and environmental issues are the major concerns in the river linking projects, since the rivers due to force of flow might change the course once the river linking is completed, this might create huge problems with respect to the environmentRead MoreHimachal Pradesh an Overview9238 Words   |  37 Pagesdances that are specific to certain regions and are best performed by the people of that area.   Some of the dance forms of Himachal are Losar Shona Chuksam (Kinnaur), Dangi (Chamba), Gee Dance and Burah dance, (Sirmour), Naati, Kharait, Ujagjama and Chadhgebrikar (Kullu) and Shunto (Lahaul amp; Spiti).   As for the music of Himachal Pradesh is concerned, there is no classical form though there plenty of folk music to listen to.

For example, Singapore, in the tropics, has a hot wet climate, while continental Mongolia always has cold winters. The ecosystems, agriculture, livelihoods and settlements of a region are very dependent on its climate. The climate therefore can be thought of as a long-term summary of weather conditions, taking account of the average conditions as well as the variability of these conditions. The fluctuations that occur from yearRead MoreThe Holy River of India-River Ganges9512 Words   |  39 PagesGanges is mainly in India, but also flows through Bangladesh before emptying into the Bay of Bengal. The river, about 2,510 km (1,560 mi) long , rises in a snowfield called THE GANGOTRI GLACIER, situated among three Himalayan mountains all more than 6,706 m (22,000 ft) high. It issues as the Bhagirathi River from an ice cave, 3,139 m (10,300 ft) above sea level, and falls 67 m per km (350 ft per mi). About 16 km (10 mi) from the source is Gangotri, the first temple on its banks and a traditional resortRead MoreGround Water Depletion6229 Words   |  25 Pageseach year) and are growing at a rate of 5.5 percent per annum.
