This study by Institute for Social and Economic Change (ISEC) aims at understanding the livelihood patterns of fishermen within the Tungabhadra sub basin, a tributary of river Krishna located in peninsular India. Lack of integrated approach in development initiatives and water management plans warrants the need for Integrated Water Resource Management to support livelihoods. The study focuses on fisheries as a source of livelihood, current status and institutional support available, people dependant on it, development initiatives and suggestions for improvements.

This paper focuses on water management techniques used in two tanks constructed by the kings of the Vijaynagar Empire.

The first example taken, is that of the Anantraj Sagar built by the son of the minister of Harihar. The lake is still in use and there are inscriptions on stone near it which provide a thumb rule to constructing lakes. Construction of this lake began in 1369 and was completed in 2 years. The paper states that the length of the dam was 5000 dand, width was 8 dand and the height was 7 dand (One dand is about one metre).

These two documents from the KSPCB website, provide monthly water quality status data, for the rivers Tungabhadra, Cauvery and Kabini, monitored between January to June 2007, at various points along the rivers.

The data recorded are Temperature, pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Faecal Coliform.

The below is a brief summary of the events:

OVERALL SITUATION

Heavy rains due to depression in the Bay of Bengal and low pressure from the Arabian Sea from Sep tember 29 to October 2 have caused flash floods in north Karnataka and the Rayalaseema region of Andhra Pradesh, affecting nearly two million people and claiming 210 lives. In Karnataka, 15 districts are affected and 161 people have nearly tw millionperished. In Andhra Pradesh, five districts were hit by the flash flood and 49 people have lost their lives. However, of the two million, 1.4 million people affected are from Andhra Pradesh.

The case study of the irrigation infrastructure of Tungabhadra river zooms in on the river, to examine the various schemes on it. Taking the particular case of the Tungabhadra in the Krishna river basin and following the river flow as it is subject to various schemes in time and space, it shows how simmering tensions are likely to manifest as full-fledged conflicts. 

This deals with the proceedings of the first stakeholder meeting held under the STRIVER project for the Tungabhadra River Basin. The meeting involved representatives from different stakeholder groups like the Irrigation Departments and Command Area Development Agencies (CADAs), Forest Department, Pollution Control Board, Fisheries Department, NGOs and civil society groups from the Tungabhadra basin, representatives of Water User Associations and farmers. Only the representation from industries was lacking in this meeting.

As part of the research study, River Basins and River Basin Organisations in South Asia, done by the Society for Participatory Development Hyderabad, CapNet South Asia (Read More) and Gomukh Environmental Trust for Sustainable Development Pune (Click Here), data about individual river basins has been collected for the river basins in South Asia.
