Creating a repository for India’s water resources data
WRIS provides a comprehensive, authoritative and consistent data on India’s water resources in a standardised national GIS framework. Amita Bhaduri posted 2 months 2 weeks ago

Water, a scarce natural resource fundamental to life, livelihood, food security and sustainable development is required in every sector i.e. domestic, agricultural, industrial and environmental. Its source is precipitation, the usual forms being rainfall, snowfall etc. These in turn build surface and groundwater resources in the form of rivers, lakes, ponds, glaciers, groundwater etc.

Data-driven ‘water and agriculture’ planning: The big picture
If data was better organized and available for download in more ‘user-friendly’ formats, its utilization would improve manifold. Amita Bhaduri posted 3 months ago

India is fortunate to have a rich tradition of public data collection and compilation.

The quality of our public data is highly variable, yet if analyses and interpretation are done keeping in mind some of the limitations, the datasets can be a precious resource at the meso and macro level. (Image: Pixabay)

Data, a reusable asset
Can we design capabilities to ingest, protect and use water data in ways that amplify value for its users? Amita Bhaduri posted 3 months 2 weeks ago

A quick search for the word data on India Water Portal results in a flood of queries - people are looking for water data - for specific villages, cities or for the entire country. 

Water data needs to be liberated from the custody of one set of users and a single programme making it a reusable asset that each programme and actor builds on. (Image: Needpix)
