This report of the Working Group to advise Water Quality Assessment Authority (WQAA) on the minimum flows in the rivers outlines the principles behind environmental flow assessments, provides a description of methods that have been used to assist with such assessments, and highlights the features that will increase the chance of successful implementation of environmental flows. 

This is a translation from the Nepali of an article that first appeared in Nepal magazine on 11 July 2010. Dipak Gyawali is member of the panel of experts reviewing the Mekong River Commission’s Basin Development Plan and vice-chair of the technical committee of the UN’s World Water Assessment Programme. He was Nepal’s Minister for Water Resources during 2002-03.

Many Nepalis would be shocked to hear that Bhutan will face load- shedding from the coming winter. The citizens of Nepal have, after all, been told for decades that Bhutan has done a great job of developing hydroelectricity, that it has earned significant money by exporting electricity to India, and thus it has been able to achieve the highest per capita income in Southasia. Conversely, Nepal has been ridiculed for wallowing in ‘empty nationalism’ and stirring ‘needless’ controversies over the Mahakali Treaty of 1996 (for water sharing on the Mahakali River) as well as hydropower projects such as the West Seti, both of which involve export of electricity to India.

A peer paper in Science Magazine focuses on the core of a riverine system, the upstream basin, and its impact on the entire river basin.

A huge controversy has been generated in recent days over the much quoted lines in the IPCC’s 2007 report: “Glaciers in the Himalaya are receding faster than in any part of the world and, if the present rate continues, the likelihood of them disappearing by the year 2035 and perhaps sooner is very high if the Earth keeps warming at the current rate” (Working Group 2, page 493). We do need to question how a statement of such magnitude, without peer review, made its way into the IPCC report. That it was discovered,externally, more than two years later raises concerns about both the mindset and the weakness of the processes of the IPCC in checking and correcting information they collate, information that is so vital in the global debate. However, to question the credibility of the science of the global warming, supported as it is by a wealth of empirical evidence, or to question IPCC’s work, as is happening in some quarters, is gross exaggeration and sometimes driven by dubious and malafide intentions.

It was an uncharacteristically sunny day for the monsoon, with blindingly clear skies. Namgye Chumbi was weeding his potato garden in Phakding by the Dudh Kosi on the morning of 4 August 1985.

There weren't too many trekkers on the trail. The Dudh Kosi was tumbling noisily over boulders nearby. Around two in the afternoon, the river went quiet. Namgye sensed danger.

"I noticed that the white water had turned muddy brown, and in the distance I heard a thundering sound like an approaching helicopter," recalls the 50-year-old farmer. "I looked upstream and saw this huge wall of dark brown water approaching very fast."

The programme entails a panorama of actions working towards understanding future climate change impacts on Himalayan river ecosystems and vulnerable communities for the development of adaptation strategies; implementation of pilot sites; and raising the awareness of climate change impacts on Himalayan river basins, in addition to urging specific adaptation strategie

These floods cause havoc with human life, flora and fauna of the area and the infrastructure in the region.

The Dig Tosho Glacier lake outburst in August 1985, destroyed the nearly completed Namche hydropower plant and all the rails, roads, and other infrastructure in its course.

The Himalayas' permanent ice cover is around 97,000 sq.km. with 12,930 sq.km. volume of ice and snow: 10-20 % are covered by glaciers and 30-40% are seasonal snowfalls. The Himalayan streams and rivers are fed by the melting of snow and ice of approximately 500 sq.km / year.

As observed by the United Nations Environment Program (GRID-Arendal) ice and snow are major components of the climate system. That is why human induced climate change can be first observed in Polar Regions where most of Earth's snow and ice are concentrated. In these areas global warming induces the progressive melting of ice and snow.
