Bagmati river in Kathmandu: From holy river to unthinkable flowing filth

Ajaya Dixit initiated his presentation with a general account of how rivers shape the landscape and how riverine ecosystems have nurtured society and kept civilisations vibrant, cultured and creative. Dixit went on to discuss the basin characteristics of the Bagmati, a tributary of the Kosi that rises in the Shivapuri hills, north of the Kathmandu valley. Around fifteen percent of the basin area (3700 sqkm) lies in Nepal, while the remaining is in India. The average annual rainfall in the basin is 1400 mm and is more than 2000 mm in the hills. Bagmati is a seasonal river with rainfall and springs as its main source. Its mean flow is 15.6 cubic metre/second and low flow is 0.15 cubic metre/second in April.

Kathmandu lies in the Upper Bagmati basin and studies suggest that an ancient lake called the Paleo-Kathmandu lay within the Kathmandu valley as a lacustrine formation. Early settlers lived in lower slopes and used springs and river in the upper reaches. When they moved to the valley floor, they built dongia dharas, which are stone water spouts fed by the unconfined aquifers and delivered water through surface channels. Even today, dongia dharas dated back to 1500 years exist. The state built canals (raj kulo) tapped the upper stretches of the rivers close to the mountains. Rivers and irrigation helped recharge aquifers and ponds.

However, rising urbanisation has damaged these ancient artifacts. Over the last sixty years Kathmandu has expanded massively and its population has increased from 0.41 million in 1951 to 2.6 million in 2011. The city has a huge transient population aside from this, reducing it to a concrete nightmare. Seismologists suggest that Kathmandu is a rubble city in the making. Though the Bagmati river flow has not changed significantly in the last seventy years, the character of the river has been transformed significantly during the period 1970 to 1990. The river has been canalised while the dumping of the city’s garbage into it continues. Dixit identified a plethora of problems faced by the river such as upstream water diversion for drinking water needs, disposal of untreated liquid waste, disposal of solid waste, river jacketing for roads and commercial activities, sand mining and physical encroachment.

The state of the river is an outcome of the current approach to waste management particularly liquid waste management. Three types of waste water namely yellow water flux, grey water and yellow black flux are being generated and flowing water is being used as a vehicle to dispose these. The idea of a water based disposal system e.g. flush toilet embedded in Victorian engineering has led to a technological lock-in with the result that the notion of a natural hydrological cycle has undergone a fundamental transformation.

All the same, the bulk of the load in the river is biological though there are some factories releasing effluents. In the last 20 years some of them have been closed or relocated and the river now stands a chance of being salvaged.

The public art outreach project was organized by the Max Mueller Bhavan in association with the Government of Delhi and the Goethe-Institut (Hamburg, Germany) as a part of the “Year of Germany in India” programme opened on 5^th of November, 2011. The art exhibition which continued till the 19^th of November co-curated by artist Ravi Agarwal who is also a practicing environmentalist (Director, Toxics Link) along with German artist, Till Krauser attempted to create a pulsating synergy between the Yamuna and Elbe rivers.

Orissa was hit by two spates of flood in September 2011, the first one being caused by heavy rains in the Mahanadi catchment and release of huge discharges from Hirakud dam. The second one was caused by heavy rains and flooding of Brahmani, Baitarani and Budhabalanga rivers. These floods point to the loopholes in river basin planning and management and calls for urgent attention of planners and policy makers. 

Reap what you sow, eat what you grow - A film by Suma Josson

It depicts how applying ecological principles and practices to maintain soil fertility, to manage crop health, and to keep soil and water in a good condition is especially relevant to the urban setting. The film focuses on the work being done in the urban farms, yet it can be seen as much more than that and, understood as a vision on healthy products, healthy production systems and as a way of life.

The drafting of a new legislation on these issues was taken up by a Group of Ministers in May 2007 and this is the second draft bill presented by the UPA Government.

This study attempts to develop a case study of the Western Yamuna Canal Command in Haryana with the purpose of developing a general picture of the institutional environment and arrangements related to water resource development and use in the State of Haryana. It is based on a review of water law, policy and administration and helps draw conclusions on whether the existing governance systems are meeting the current needs and suggests alternate options. The study has attempted to test the following hypothesis –
