A one-day “Action plan workshop for the rejuvenation and sustenance of Arkavathi river basin”, was organised on 25th July 2009, by the Global Academy of Technology and Geological Society of India at Bangalore, to discuss the future of the dying Arkavathi river and Bangalore's precarious water situation, and to develop concurrent implementable action plans to address the problem. The Arkavathi is a tributary of the river Kaveri, originating in Nandi Hills in Chikkaballapur district, that provides about 20% of the total water requirements of Bangalore, with Kaveri providing the remaining 80%.
The discussion was organised along the following range of topics:
- Status of naturally endowed water resources as revealed by maps and satellite images
- Impact of urbanization on the natural system
- Changing scenario of hydrology of the region
- Issues related to water pollution
- Status of rainfall and scope for rainwater harvesting
- Legal framework for follow-up action
- Integrated use of water resources
- Administrative boundaries and role of elected representatives
Participants in the workshop included elected representatives of Arkavathi basin, Bureaucrats, Non-government organizations, Academic institutions, Government officers, Students and Citizens. The workshop was sponsored by Bangalore Development Authority, Arghyam, Karnataka State Pollution Control Board, Karnataka State Industrial Investment and Development Corporation, Karnataka Power Corporation Limited, Karnataka Science & Technology Academy and Bangalore Water Supply and Sewerage Board. A total of 126 participants from 36 organizations/experts, participated in the workshop.
The workshop started with a briefing on background to the issue, discussion on various themes and dimensions to the problem, presentation of related technical papers by various sector experts, enlisting of views from participants and drawing up of final recommendations.
