Every country in the world is affected by water shortage or water scarcity.In 2015, the World Economic Forum listed it as the largest global risk in terms of potential impact over the next decade.The United Nations estimates that of the 1.4 billion cubic kilometers of water on earth, just 200,000 cubic kilometers represents the fresh water available for human consumption. The Rediff Labs team looked at how India is affected by this situation and found that India is facing an acute water shortage.The main reason behind this is the mismanagement of water by the government.In India, there are a lot of efficient ways to save water but the implementation of these processes is questionable.
What makes this project innovative?
We considered the reservoir wise water storage data and the departure from normal storage in percentages and categorized it.This data article was uploaded before the arrival of the monsoons so that our readers would be aware of the current storage level and how it has increased or decreased after the monsoon, based on the rainfall received in each state.

Source and methodology
For this data article, we at Rediff Labs analysed the current storage departure water in 91 reservoirs across the country. We looked at the current water storage of major reservoirs from a 10 year average perspective; this compares the current water level in a reservoir to the 10 year average. In order to do so, we used data from the Central Water Commission of India.The data was visualized on a map with the help of circles. The size of the circle represented a reservoir’s full level. The color of the circle shows the departure from the average of the water level in 10 years.This showed us that India has normal storage in the Narmada, Mahi, Ganga, Sabarmati, Godavari, Tapi, Mahanadi and their neighboring eastward-flowing rivers.Close to the normal level of storage is available in west-flowing rivers of south India.The Indus and the rivers of the Kutch are water deficient, while the Cauvery, its neighboring east-flowing rivers, and the Krishna basin are highly deficient.We visualized the current storage departure in percentage form as on May 28, 2017, keeping the 10-year average in mind. We categorized the water storage for each state in India and found that states like Tripura, Uttar Pradesh, West Bengal and Madhya Pradesh have more than 75 percent access to water and states like Tamil Nadu, Uttarakhand, and Andhra Pradesh face a water shortage of more than 50 percent.Our data showed that one part of India gets good access to water while another part suffers from a serious water shortage.
