Living rivers, dying rivers: Rivers in the Western Ghats

River stories from Maharashtra: Many morals to learn 

Parineeta Dandekar’s presentation began with an account of some statistics related to Maharashtra, the third largest state in India. Regarding the state of water resources in Maharashtra, she noted that of the five river basin systems, 55 percent of the dependable yield is available in the four river basins (Krishna, Godavari, Tapi and Narmada) east of the Western Ghats. These four river basins comprise 92 percent of the cultivable land and more than 60 percent of the population in rural areas. 45 percent of the state's water resources are from west flowing rivers which are mainly monsoon specific rivers emanating from the Western Ghats and draining into the Arabian Sea.

With 1821 large dams and more in the offing, Maharashtra has the maximum dams in the country (35.7%). However, the proportion of gross irrigated area vis a vis the gross cropped area at 17.8 percent is much lower than the national average of 44.6 percent. The contradictions from the state, which is home to the highest number of dams, were discussed. In nearly 70 percent of the state’s villages (around 27,600 villages), water is either not available within 500 metres distance, or within 15 metres below ground level or when available is not potable (World Bank, Promoting Agricultural Growth in Maharashtra, Volume 1, 2003).

Dandekar discussed the World Bank funded Maharashtra Water Sector Improvement Project (MWSIP) initiated in 2005 whose main components were establishment, operationalisation and capacity building of Maharashtra Water Resources Regulatory Authority (MWRRA); establishment of river basin agencies in Maharashtra; and restructuring and capacity building of the Water Resources Department. The MWRRA Act (2005) has been amended, taking out the clause for equitable water distribution, and granting the Cabinet the rights to have the last say about water entitlements. This has led to a diversion of water for irrigation from the vulnerable, suicide-prone Vidarbha region to thermal power plants. According to Prayas, “entitlements of more than 1500 MCM have been changed from agriculture to industries and cities”.

Safe water dissemination workshop by PATH held on January 19-20, 2012 at New Delhi
PATH organized a Dissemination Workshop of its Safe Water Project at India Habitat Centre, New Delhi on January 19-20, 2012. Posted on 07 Feb, 2012 10:15 PM

Guest post: Amita Bhaduri

Through the Safe Water Project, it is seeking complementary solutions to sustainability and scale-up by exploring the potential for commercial enterprises to produce, distribute, sell, and maintain Household Water Treatment and Storage (HWTS) consumer products to low-income populations. The workshop shared learnings and tools from PATH’s Safe Water Project and presented the experiences of other organizations that are leveraging market-based approaches to achieve a sustainable public health impact.

Global change, wastewater and health in fast growing economies - Paper published in the journal Current Opinion in Environmental Sustainability
This paper published in the journal Current Opinion in Environmental Sustainability draws attention to the serious issue of poor water quality in the developing economies. Posted on 02 Feb, 2012 11:35 AM

It argues that among the water challenges in the 21st century, the water quality health nexus is one of the most serious challenges that will need to be addressed at an urgent level.The paper directs attention at the rapid and unequal growth and development patterns emerging in developing economies and the impact of this development on the environment and human populations. The paper directs attention to the negative impact of this development on one of the important natural resources such as water and the linkages between water quality and public health of populations.

Evaluation of physico-chemical characteristics in groundwater using GIS – A case study of Chinnar sub-basin, Cauvery River, Tamil Nadu, India
This study uses GIS to assess the potability of groundwater and the spatial variation of groundwater parameters in Chinnar sub-basin, Tamil Nadu. Posted on 20 Jan, 2012 04:26 PM

The study found that the groundwater of the basin is extremely hard with total hardness, magnesium and potassium contents being above the permissible limits. Thirty nine out of 57 samples exceed the allowable limits for fluoride.
