Rapid urban growth, scarce water resources and a high risk of natural disasters pose serious challenges for Leh's urban planning and governance.

Across South Asia, small and medium-sized towns are rapidly expanding. Urbanisation has made inroads into the entire Himalayan region. Mountain urbanisation poses a need for assessments of emerging risks and vulnerabilities in environmentally sensitive regions. These areas are marked by population growth and migration from rural settlements as well as limited availability of suitable space for construction, often leading to building activities in landslide or flood-prone areas.

The effects of climate change are felt by the indigenous communities residing in the Himalayan region. How are they coping with these changes?

Mountain ecosystems are highly sensitive due to ecological fragility, geomorphologic instability but are blessed with vast eco biodiversity. Climate change impacts in the form of temperature rise, unpredictable and decreased rainfall, glacier melt, prolonged summers and short winters and changes in the seasonal cycle are happening at a more severe pace in the mountain areas making it more vulnerable to their impacts.

A study assesses risks associated with Pancheshwar dam in the light of environmental impact observed for the Tehri project.

Mahakali, also known as Sharda in India, gushes through the hilly tracts of Nepal and Uttarakhand, collecting its water from the numerous streams it receives on the way. Like all rivers meandering through the lush terrains and forests of Uttarakhand, Mahakali too has become a cause of disagreement between the state and the people due to the widespread community opposition to the proposed dam on it at Pancheshwar.

A study suggests water towers of Asia contain less water than estimated.

The Himalayas are often called the water towers of Asia because of the vast amount of water locked in the form of ice in thousands of glaciers there. But concerns relating to climate change have often put a question mark on future water availability from these glaciers. Now a new study on ice thickness of glaciers has estimated that glaciers in the Hindu Kush Himalayas might contain 27 percent less ice than previously suggested.

The Himalayan wetlands are under threat due to unregulated urbanisation and unsustainable tourism. Urgent attention at the policy level is the need of the hour.

Wetlands are very important and productive ecosystems that support a wide range of plants and animals and provide livelihood opportunities to local communities in India. However, they are increasingly being threatened by rapid urbanisation, pollution, developmental interventions, unsustainable management practices and encroachment.

An experiment to siphon off water from glacial lakes to avoid floods from lake outbursts may soon prove to be successful.

Disasters managers and scientists in Sikkim are keeping a close watch on a lake formed due to the melting of glaciers to see how successful is an experiment they began two years back to siphon off excess water from the lake to prevent it from bursting.
