Climate change may reduce water available to cool power plants
A study finds that India may run out of water to cool power plants in the near future. Amita Bhaduri posted 1 year 3 months ago

Climate change and over-exploited river basins may leave developing countries in Asia, such as India and China, without enough water to cool power plants in the near future, according to a study.

Climate shocks and gender vulnerabilities in the Upper Ganga basin
Study points to vulnerabilities faced by women in the mountains and plains of Uttarakhand, which is likely to only increase with climate change. Amita Bhaduri posted 1 year 3 months ago

Socially constructed notions of the different roles and responsibilities of men and women have a huge bearing on access to and control over resources, and subsequently on their vulnerabilities. More often than not, this leads to vulnerabilities that are skewed towards women, more than men.

300 million people will be vulnerable to annual coastline flooding by 2050
The number of people vulnerable to floods triggered by climate change by 2050 is triple that of previous estimates, according to a new study. Amita Bhaduri posted 1 year 4 months ago

A new research study by Climate Central, a US-based non-profit research group has projected that 300 million people could face annual coastal flooding triggered by climate change by 2050.

India’s rivers carry deadly pathogens
A global study on pathogens in rivers finds that Indian rivers harbour dangerous levels of diarrhoeal disease-causing pathogens. aartikelkar posted 1 year 4 months ago

Diarrhoea is one of the leading killers of children under the age of five in developing countries. Diarrhoea is rampant in India, with diarrhoeal diseases being the most prevalent of all waterborne diseases in the country.

Mapping Pune’s aquifers
Groundwater use has doubled in Pune. Comprehensive mapping of groundwater resources and better management and governance is the need of the hour. aartikelkar posted 1 year 4 months ago

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.

Ice stupas, the contested water towers of Ladakh
While ice stupas have been hailed as sustainable solutions to the water problems of Ladakh’s villages, the locals think otherwise. aartikelkar posted 1 year 4 months ago

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.

Manipur’s floating lake at risk
A study using remote sensing techniques assesses significant changes in land use in Loktak lake. Amita Bhaduri posted 1 year 4 months ago

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.

Farm ponds change farmers’ fortunes
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. aartikelkar posted 1 year 5 months ago

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.
