Climate change real, warns Pangi tribe
The effects of climate change are felt by the indigenous communities residing in the Himalayan region. How are they coping with these changes? aartikelkar posted 1 year 8 months ago

Mountain ecosystems are highly sensitive due to ecological fragility, geomorphologic instability but are blessed with vast eco biodiversity.

Food security with flood, drought-resistant rice crops
New drought and flood tolerant rice varieties can ease water constraints and ensure food security, study says. Amita Bhaduri posted 1 year 8 months ago

In recent years, cycles of extreme drought and severe flooding have affected the country’s water availability and crop production. The trend can be attributed to climate change. Scientists have been exploring drought and flood tolerant crop varieties to offset stress conditions that significantly constrain rice production.

GHG emissions, water footprints of dietary patterns
Rice-based diets had higher emissions but wheat-based diets used more water, says study. Amita Bhaduri posted 1 year 8 months ago

India's food system produces large environmental impacts but these vary by diets. The per capita environmental impacts of diets in India are currently lower than those of many high-income countries due, in part, to habitually low consumption of animal source foods.

Caste and farmer’s access to quality information
A study finds that farmers from socially-marginalised castes continue to be disadvantaged in accessing agricultural extension services. aartikelkar posted 1 year 9 months ago

Increase in agricultural productivity is not only dependent on material inputs, but also on farmer’s access to relevant information on crop production and farm management practices. This information is provided through agricultural extension services in India.

Environmental implications of Pancheshwar dam
A study assesses risks associated with Pancheshwar dam in the light of environmental impact observed for the Tehri project. Amita Bhaduri posted 1 year 9 months ago

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.

Borewells: Boon or bane for women?
A study shows that although borewells have improved women’s access to water in the short term, they have increased water insecurity and the suffering of women in the long term. aartikelkar posted 1 year 9 months ago

Tamil Nadu is one of the most water-vulnerable states in India that depends heavily on groundwater for irrigation. As high as 56 percent of land in the state is currently irrigated by groundwater and the remaining by tanks and canals.

What happens when you throw away pencil cells?
Study reveals how tossing of dry cell batteries in our dustbins poisons the environment. Amita Bhaduri posted 1 year 9 months ago

A recent study by Toxics Link, an environmental research and advocacy organisation on batteries titled Dead and buried: A situational analysis of battery waste management in India estimates that 2.7 billion pieces of dry cell batteries are being consumed annually in India.

Only 37 percent of world’s long rivers free flowing
A study finds out dams and reservoirs diminish diverse benefits offered by healthy rivers. Amita Bhaduri posted 1 year 9 months ago

A little over a third of the world's 246 long rivers remain free-flowing, as per a study by a team of 34 international researchers, including those from McGill University in Canada and World Wildlife Fund India.

Evacuation measures during cyclones in Odisha
Study indicates need for institutional capacity-building programmes in order to have high compliance with evacuation orders during cyclones. Amita Bhaduri posted 1 year 9 months ago

Life is getting back to normal after an ‘extremely severe’ cyclonic storm Fani hit India’s eastern coastline. It ripped through several districts of Odisha and West Bengal and brought in torrential rains and winds of up to 200 km/hr.
