While ice stupas have been hailed as sustainable solutions to the water problems of Ladakh’s villages, the locals think otherwise.

Ladakh, the arid Himalayan desert, is a high elevation borderland located close to the Union Territory (UT) of Jammu and Kashmir, in India. Water here originates from glaciers in the high altitude mountains that tower over Ladakh’s villages. Simple earthwork irrigation channels tap meltwater from streams that originate from these glaciers. The glaciers are extremely sensitive to seasonal variations and serious concerns have been raised in recent years on the impact of climate change on glacier recession and the subsequent sustainability of water resources in the region.

A study using remote sensing techniques assesses significant changes in land use in Loktak lake.

Loktak, the largest freshwater lake in North East India is also known as the ‘floating lake’ for the numerous phumdis or masses of vegetation it supports. The phumdis float around on the lake’s surface due to decay from the bottom. Some are so large that the indigenous fishing folk Meiteis have constructed makeshift floating huts locally known as phumsangs on them.

Groundwater, drawn at rapid rates from peri-urban areas of Hyderabad is now turning into a commodity, controlled and distributed by a few, to meet the needs of the urban elite.

Peri urban spaces swept up in the urbanisation tangle

Urban growth and expansion of cities is increasing the demand for land and water, increasing pressure on resources available not only in urban, but also in peri-urban areas. State policies often use peri-urban spaces and resources to meet the needs of urban populations; for instance, they use grazing lands for urban infrastructure, sewerage and water treatment plants or for special economic zones.

While farm ponds in Jharkhand have helped farmers increase yields, they have also exposed them to the risk of price fluctuations, highlighting the need for ‘beyond the farm’ interventions.

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.

It is time water policies in India acknowledge that many large dams have aged and can no longer be looked upon as the only path to water security.

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.

Open defecation plays a key role in solving the puzzle of persistent childhood malnutrition in India, says study

A pig snorts after emerging from the open drain that passes through a slum in the Digha area of south Patna. Small children crawl on the road nearby with slime dribbling from their nose. Children can be seen picking through garbage at the local dump and for ghongha (snails) at the local talaab (pond).

A study develops a peri-urban and rurban water and sanitation index for Pune.

Drinking water programs in India treat urban and rural areas separately, generally neglecting the special characteristics of settlements referred to as peri-urban – those on the outskirts or peripheries of urban areas, or “rurban” settlements i.e. rural areas with urban facilities.

A study shows how the open space on the western bank of the Sabarmati river in Ahmedabad acts as a heat sink.

A study published in the Journal of Remote Sensing and Space Sciences, analyzing the cooling effect of the city of Ahmedabad’s water bodies, has thrown up some interesting findings. The east bank of the Sabarmati river, which flows through Ahmedabad, was found to be significantly cooler than the west bank, witnessing a greater drop in temperature even during summer. The study provides direct evidence of how water bodies affect temperature variations.
