Groundwater contamination has emerged as an alarming issue in India and a recent UN report reveals that India ranks 120^th among the 122 countries in terms of water quality index. As high as 70 percent of the water supply in India is contaminated, resulting in nearly 0.2 million deaths each year.

Droughts in India: types, causes and effects

Droughts are greatly feared in India, impacting food production, the economy and the livelihoods of millions of farmers. 60% of India’s population is engaged in agriculture.

Pune continues to face a water crisis every summer despite having sufficient water, thanks to its geographical location and plentiful natural water assets. While enough of its water needs are taken care of by water supply from the Khadakwasla dam, the use of groundwater to meet the needs of the population continues to increase.

India has witnessed extreme weather conditions this year. While parts of the north and south have battled drought like conditions this summer, the northeast and western coastal areas witnessed heavy rains and floods.
While climate change has been highlighted as one of the reasons for these extreme events, experts argue that human factors, faulty models of development and the narrow perception of droughts and floods at the policy level has worsened the situation in India.

The Water Future Conference in Bangalore last week, saw many from the scientific community, academia, research, civil society and the media come together to discuss the state of water resources across the world and in India, as well as future pathways and scenarios, and different technological and institutional solutions to accelerate the implementation of the water SDGs and the 2030 Agenda targets, leaving no one behind.

Arecanut is generally grown in the Malnad area of Karnataka, which receives high rainfall. However, it is also grown in dry land areas of Tumkur district, also in Karnataka, using groundwater. Arecanut cultivation area doubled from 5851 hectares in 1990-91 (Kumar 2003) to 12,628 hectares in 2001-02 (DES GoI); and nearly doubled to 22,058 hectares in 2008-09 (DES GoI).

While most parts of the country are facing a water crisis, here’s a case from the arid state of Rajasthan, where decentralized initiatives are solving water issues. Dungarpur in southern Rajasthan has exemplified how community participation with local level planning processes are working towards improving rainwater harvesting and recharge of groundwater.

Vishwanath Srikantaiah, popularly known as the 'Rainman', has been in the news recently for his ambitious project to build one million recharge wells in Bengaluru. Given the dire situation we find ourselves in vis-à-vis water, the initiative could not have come at a better time.

India is, by far, the world’s largest groundwater economy. India’s annual withdrawal of fresh groundwater (253 Billion Cubic Metres in 2013) amounts to one fourth of the global total and is more than that of China and the US combined. Over 80% of water extracted is used in agriculture. The share of tubewells in net irrigated area rose from a mere 1% in 1960-61 to over 40% in 2013-14.
