Effects of land use change on soil organic carbon stock in Balkhu Khola watershed south western part of Kathmandu Valley, Central Nepal
Soils of the world are potentially viable sinks for atmospheric carbon and may significantly contribute to mitigate the global climate change. Soil organic carbon (SOC) content exhibits considerable variability spatially both horizontally according to land use and vertically within the soil profile. Land use and management are among the most important determinants of SOC stock. Present study was...
Implications of climate change on biodiversity in Nepal: Some observations and opportunities

Now there is no doubt among scientific communities that earth is getting warmer due to greenhouse effects leading to unintended changes in climatic patterns. This paper attempts to address some of the pertinent questions of climate change impacts in Nepal and then emphasizes on efforts required to make community forestry an eligible sector for international climate funds. Importance of the...

Mountain waters: Climatic and hydrological sensitivity
Introduction to special Section of the journal "Hydrology and Earth System Sciences", which collects a selection of six papers presented at the EGU First General Assembly Session on Mountain Waters: climatic and hydrological sensitivity.
Adaptive management of upland rivers facing global change: General insights and specific considerations for the Rhone basin
The growing awareness of complexities, the unexpected consequences of management strategies and an increase in uncertainties have triggered critical reflection about prevailing water management paradigms. This paper provides arguments for the need to change towards more integrated and adaptive water management regimes. The example of the Rhone basin is used to illustrate the challenges upland...
Mountains of the world: Water towers for the 21st century
Mountain and Hydrology Research has a long tradition, but only the Rio Conference 1992 created a real breakthrough for a new awareness about the mountains of the world and their natural and human resources. In the years 1997 and 1998 the mountains as water towers for a thirsty planet got a special interest of the UN institutions, which led not only to the International Year of Mountains 2002 and...
Climate change and water resources: Potential impacts and implications
The recurring drought and heat observed over large portions of the western U.S. have enerated adverse and costly effects, including lost agricultural productivity in rainfed regions of the mid-west and Great Plains, record wildfires in Oregon, Colorado and California, and large fish kills in California’s Klamath River triggered by warm water temperatures. Drought has persisted for nearly a decade...
Impacts of climate change on the management of upland waters: The Rhone river case
The Rhone river watershed covers a surface of 98 000 000 km2, including 10 000 km2 in Switzerland. Most of the discharge originates in the Alps, but a significant contribution is provided by the Jura Mountains and by the western Massif Central. The main river are the Rhône, the Saône, the Isère and the Durance. The total discharge at the sea 1700 m3.s-1. Since 10 years, several models have...
Rosenberg international forum on water policy: Managing upland watersheds in an era of global climate change
The Rosenberg International Forum on Water Policy was created in 1996. It is named for Richard Rosenberg, former Chairman of the Bank of America. Upon Mr. Rosenberg's retirement in 1994, the Bank of America endowed the University of California in his name with resources to help support an invitational biennial water forum for the world's leading water scholars and senior water management...
Environmental challenges and human security in the Himalaya

Mountains form one of the most important bio-geographical resource zones of the world. They are remote areas covering 52 per cent of Asia, 36 percent of North America, 25 per cent of Europe, 22 per cent of South America, 17 per cent of Australia, and 3 per cent of Africa making up, in total, 24 per cent of the earth's continental surfaces. They encompass some of the most awe-inspiring...
