The TWO Analysis: Introducing a methodology for the transboundary waters opportunity analysis

This report presents a conceptual framework that can be used by stakeholders concerned by the development and management of shared freshwater resources. The objective is to promote the sustainable and equitable use of transboundary water resources, and to clarify trade-offs relating to development. The report outlines a concept for analysing potential benefits in a transboundary river basin to...

Using satellite-based rainfall estimates for streamflow modelling: Bagmati Basin

In this study, a hydrologic modelling system that uses satellite based  rainfall estimates and weather forecast data for the Bagmati River Basin of  Nepal is described. The hydrologic model described is the US Geological Survey (USGS) Geospatial Stream Flow Model (GeoSFM). The GeoSFM is a spatially semidistributed, physically based hydrologic model.We have used the GeoSFM to estimate...

Tibet: Enduring spirit, exploited land

The book describes the traditional lives of nomads and farmers and their practices in co-existing with the environment. The environmental ethic developed by the Tibetans over millennia now threatened by Chinese social system and development practices, and the massive transfer of Han Chinese into Tibet. These events have gained increased significance for the world as dependence on the natural...

River channel response to short-term human-induced change in landscape connectivity in Andean ecosystems
The drainage basin of the Deleg River (88 km2), located in the southern Ecuadorian Andes, was studied to assess the geomorphic and hydrologic response of a fluvial system to human-induced environmental change in its contributing area.

Historical data on land use, channel morphology and sedimentology were collected, based on a spatial analysis of aerial photographs (1963...

Spatial variation of suspended sediment concentrations in a tropical Andean river system: The Paute River, southern Ecuador
Tropical mountain ecosystems are sensitive to environmental change brought about by natural and anthropogenic processes. The steep topography, shallow soils and unsustainable land use practices following forest conversion often lead to enhanced rates of geomorphic activity including soil erosion, landsliding and fluvial activity. Rapid demographic growth and socio-economic development have...
Water cycle projection in Asia by super-high-resolution climate model
In this presentation, streamflow increases in most of rivers in east Asia and south Asia are described, but with decreases in south-east Asia and western Asia.
Beyond counting: Biodiversity drives system Earth
Following from the conference in Rio de Janeiro and landmark articles such as those by Lawton & May (1995) the broad public became aware that the current loss of organismic taxa and the rate at which this occurs are corresponding to a disaster of geological time scale dimension. The loss of taxa is irreversible, and the more we lose the more depauperate the globe’s genetic reservoir...
A simple and cheaper means of river crossing system in Nepal
There are more than 6,000 rivers and streams in Nepal and in many places there are no means of crossing. Many people have lost their life or been injured during monsoon floods, attempting to cross by swimming or using grass ropes and wooden pulleys, simple boats or wooden rafts. Wire bridges (tuin) are an indigenous technology and one of the most common structures for river crossing in such...
Annual runoff from glaciers of the Nepal Himalaya

Recent concerns related to the potential impacts of the retreat of Himalayan glaciers on the hydrology of rivers originating in the catchment basins of the Himalaya have not been accompanied by any analysis describing the role of glaciers in the hydrologic regime of these mountains. This note presents an estimate of glacier runoff from the altitudinal belt above 5000 meters above sea level for...

Robbing banda to pay hamir
While the objectives are lofty, the feasibility studies for river interlinking are tacky, inept and based on incorrect assumptions. As a student of water resource systems analysis, I was expecting detailed analytics and graphics for optimising the use of water and capital using a range of computer-based modeling techniques while attending a talk on the promise of the river inter-linking project...
