Fluorosis is a bone disease that is caused by a high consumption of fluoride. Most think that it is a direct result of drinking water with high fluoride content alone but it isn’t so. Nutrition plays an  important role in the onset of this disease.

How do groundwater irrigation and energy supply influence each other ? - Talks from the IWMI-Tata Annual Partners' Meet held at Anand in November 2012
This article presents videos of related talks, short descriptions of each video and links to background papers from the IWMI-Tata Annual Partners' Meet in 2012. chicu posted 8 years 2 months ago

India is the world's largest consumer of groundwater where it is extensively used for irrigation. However, there is a considerable waste of this valuable resource. While a part of this waste can be attributed to a lack of incentive for conservation, unmetered electricity supply contributes greatly to this problem. This has led to the formation of what is being termed an energy-irrigation nexus.

Several sessions at the IWMI-Tata Annual Partners' Meet in 2012 discussed this phenomenon, its causes, impact and possible management strategies. 

India’s groundwater challenge and the way forward - Economic and Political Weekly
This paper published in the Economic and Political Weekly highlights the present groundwater situation in the country Aarti Kelkar Khambete posted 10 years 3 months ago

It warns that groundwater quantity as well as quality are the two major problems that the country has been facing.

The rate of withdrawal of groundwater has reached “unsafe” levels in 31% of the districts, covering 33% of the land area and 35% of the population. The situation has dramatically worsened within a short span of nine years, between the assessments done in 1995 and 2004.

Taking the quantitative and qualitative aspects together, data indicates that a total of 347 districts (59% of all districts in India) are vulnerable in terms of safe drinking water in India. This is a matter of serious concern, requiring a new approach.

India s groundwater challenges and the way forward

The groundwater crisis is acquiring alarming proportions in many parts of the country. Strategies to respond to groundwater overuse and deteriorating water quality must be based on a new approach involving typologising the resource problems and redefining the institutional structure governing groundwater. This approach is based on the notion of groundwater as common property.
