Water Resources, Livelihood Security and Stakeholders Initiatives in a River Basin Context - An Assessment of Point and Non-point Sources of Pollution and their Impact
Project Team: Dr. Paul P Appasamy, Dr. K.R. Shanmugam, Mr. Prakash Nelliyat, Mr.Sacchidananda Mukherjee
Time Period: 2004 - 2005
Sponsored by: International Water Management Institute, Colombo, Sri Lanka and coordinated by Linkopings, Lund University, Sweden
Project Summary:
Environment and water quality 
Water accessibility is not only related to the quantitative availability of water but also by its suitability for different uses. Pollution from land and other sources is a growing problem in India and makes previously fertile land unsuitable for agriculture and creates health risks (Government of Tamil Nadu, 1999). The source areas of different types of pollution, their patterns of diffusion are an important component of water (use) budget and how they affect livelihood options.

Methodology
Agriculture in the basin has been affected due to the discharge of industrial effluents. First, an inventory of pollution sources-industrial units, towns discharging sewage, etc. will be perfected using secondary data. Based on the stakeholder discussions, land and water bodies that have been affected by pollution will be identified. Surveys of farmers in the affected villages will be taken up a sample basis. The impact on productivity and income, and hence on livelihood will be estimated for the sample farmers. Information on landless laborers who may have been displaced will also be collected from the sample villages. Drinking water problems if any and the consequences will also be discussed and data collected from the same villages. In addition, water quality monitoring of the ground water (pre-monsoon and post-monsoon) will be taken up. Soil samples also will be collected to study the impact of pollution on soil. Data will also be collected from the medical practitioners and health professionals in the area on health effect.
