Storage and Supply

The last few months have seen much debate and discussion on the fast approaching Day Zero, with claims that taps in 21 major Indian cities will dry up. People in Chennai were compelled to queue up to collect water from tankers this past June. Last year’s NITI Aayog’s report set off alarm bells that most of India’s major cities were likely to face an acute, unprecedented water shortage.

While enhanced irrigation coverage has been hailed as an important way to improve agricultural productivity, it continues to lag behind in India and agriculture continues to be rainfed, subject to the vagaries of the monsoon. High groundwater dependence for irrigation has not only led to its depletion and quality deterioration, but has also raised questions about its sustainability in the long run.

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).

Government identifies 100 wetlands for restoration in next five years

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.

NITI Aayog, the Government of India’s policy think tank, recently released the second edition of the Composite Water Management Index to enable effective water management in Indian states. It warns that the country will lose 6% of its Gross Domestic Product (GDP) by 2050 because of a water crisis. The annual per capita availability of water is expected to reduce to 1,140 cubic metres by 2050, near to the official water scarcity threshold of 1,000 cubic metres.

Greater Noida, September 5 (India Science Wire): Degradation of land, which leads to the process of desertification, is not limited to arid and semi-arid areas but is also visible in high altitude regions that get very little rainfall and are known as cold deserts.

Centre to provide 43-55 litre/day water per person to rural households by 2024

India is reeling from a severe water crisis. Large parts of the country are experiencing water-stress worsened by the ever increasing demand for water due to population growth, rapid urbanisation, changing lifestyles and consumption patterns, inefficient use of water and climate change.
