On a scale of 5, from lowest to highest, this map shows the vulnerability of various districts of the country to climate change. The map shows many of these regions are doubly exposed to the risk of climate change.

These two maps indicate the percentage of districts affected by fluoride, in each state of the country and also gives data of the range of fluoride concentration in drinking water in each state.

For Asia, this map indicates the probability of occurrence of excessive concentrations of fluoride in groundwater, on a scale of high-medium-low.

In India, salinity has three types of genesis - one, by dissolution (areas concentrated in Kutch, North Rajasthan and bordering Punjab, South Rajasthan and bordering areas of Madhya Pradesh and parts of Western Uttar Pradesh; two, by irrigation (areas concentrated in the Deccan Peninsular region of Andhra Pradesh, Karnataka and Tamil Nadu) and parts of Orissa and West Bengal; and three, by late

Trans-boundary aquifers (TBAs) of the world: This map shows the present state of information regarding the occurrence and extent of TBAs world-wide. The intention of the map is to provide a global overview of these important shared water resources and to encourage their further assessment.

In India, TBAs are located on the India-Pakistan, India-Nepal and India-Bangladesh borders.

Over a range of under 20cm to over 800cm, these two maps, give an idea of the average rainfall received by different regions in the country.

The lowest rainfall receiving areas are Rajasthan, Gujarat, Western Uttar Pradesh, parts of Haryana and Punjab, and the central peninsular region of Karnataka, Maharashtra and Andhra Pradesh.

Watersheds are natural hydrological entities that cover a specific aerial expanse of land surface from which the rainfall runoff flows to a defined drain, channel, stream or river at any particular point. The terms region, basin, catchment, watershed etc are widely used to denote hydrological units.

The map shows that Tamil Nadu, Kerala, Karnataka, Goa, Maharashtra and Gujarat are high salinity zones, and Andhra Pradesh, Orissa and West Bengal are moderate salinity zones.
