| Maps & Statistics |
Much has been said about the paucity of good quality data in the area of water. There are several aspects here: In some cases there is simply no data or no good data either from government or other sources. In some cases the government does capture data but is not always ready to make this data freely available. There is not much clarity around the rules and procedures if any, for requesting data from the government. In the case of maps, there may be perceived security issues and regional sensitivities.
As a beginning in this area, India Water Portal would like to collect at a single location whatever information is available to us. This includes data and maps already there on the web for which there is value in collecting it at a single location. We invite NGOs and other organisations to send us whatever studies they have done to add to this database and make it more useful. The effort is experimentative at the moment -- we would like to put up whatever we find on the web or elsewhere. The next step would be to make the data well-indexed and searchable. The real value-add would come when there is space for everyone to comment on individual datum, point out the gaps, inconsistencies between different studies etc.
The links below are for national-level data or local data that we would like to highlight as deserving of more attention. The state links on the right contain resources specific to individual states |

| The PAHELI report (Peoples' Audit of Health Education and Livelihoods) is a rapid assessment of the prevailing status of human development in a district and covers four major sectors: life and livelihoods, water and sanitation, mother and child health, and education and literacy. The design and execution of PAHELI was done by Pratham and PAHELI district partners. It was supported by UNDP with participation from UNICEF. |

| Floods: In India, out of the total geographical area of 329 m ha., the flood prone area has been estimated as 45.64 m.ha. Heavy flood damages were experienced in the country during the monsoon of 1955, 1971, 1973, 1977, 1978, 1980, 1984, 1988, 1989, 1998, 2001 & 2004. CWC has has calculated yearly average loss to life to be equal to 1590 with damage to public utilities Rs. 806.78 crore. Apart from the above, there are many other impacts. |

Droughts: Of the total geographical area of the country (329 M. ha) about 1/6th is drought prone. Drought is officially defined as a situation occurring in an area:
- When the annual rainfall is less than 75% of the normal in 20% of the years examined.
- Less than 30% of the cultivated area is irrigated.
The following is a link to some drought-related initiatives of the government |

| Indiastat.com is a fee-based website that provides data aggregated from various government sources. Rainfall data is presented in a variety of formats and for numerous timeframes, for example 1) average rainfall for the whole of India (1996-2005), 2) Meteorological Subdivision-wise Actual and Normal Rainfall in India (June to October, 2006), and 3) Metrological Sub Division-wise Actual and Normal Rainfall for Winter Season in India (January-February to May 2006). While these data sets are available directly from government sources at no cost, this site may be useful for those not wishing to conduct detailed Internet searches for their rainfall data. |

| The India Water Portal has a Meteorological Data application that has climate parameters on a
.5 by .5 latitude/longitude grid throughout the country, for a 100 years. The data is derived from
a research data set from the Tyndall Center for Climate Change Research in the UK. However more
sources of data especially more fine-grained data based on reliable ground measurements is always
good. Here are three such rainfall data sources for Karnataka:

| The RDPR (Rural Development and Panchayati Raj) Department of the Government of Karnataka did
extensive mapping of groundwater quality in all areas of the state and even deployed the
information on a GIS platform. The information however is not available online currently. IWP does have a hardcopy of this information and may be able to respond to requests for some of this data. |
