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.

New drought and flood tolerant rice varieties can ease water constraints and ensure food security, study says.

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. With the development of new drought and flood-tolerant rice varieties, agriculture scientists hope to ease water constraints and ensure food security.

Rice-based diets had higher emissions but wheat-based diets used more water, says study.

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. But, this relatively low per capita impact may change due to the “nutrition transition” from cereal-dominated diets towards diets high in animal-source and highly processed foods, at least among some segments of the population.

A study finds that farmers from socially-marginalised castes continue to be disadvantaged in accessing agricultural extension services.

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.

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 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.

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. The provision of subsidies by the state government for irrigation and loans for deepening of existing borewells and construction of new ones have turned borewells into a main source of water for irrigation. This has encouraged farmers to extract groundwater by drilling deeper and deeper.

Study reveals how tossing of dry cell batteries in our dustbins poisons the environment.

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. The report talks about their use in a variety of products and devices ranging from cars to mobiles, laptops, watches, television remotes, toys, medical devices and inverters.

A study finds out dams and reservoirs diminish diverse benefits offered by healthy rivers.

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. The study, which assessed the connectivity status of 12 million kilometres of rivers worldwide, found that there are about 2.8 million dams along this stretch.

Study indicates need for institutional capacity-building programmes in order to have high compliance with evacuation orders during cyclones.

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. But improved responses to the disaster by way of timely warning, advance planning, evacuation, rescue and restoration operations helped mitigate casualties and damage to the region.

A study finds women are hit the hardest during droughts due to food and water scarcity, loss of income and a range of health problems resulting from it.

Droughts are one of the most feared natural calamities impacting agriculture and food production as well as the morale of millions of farmers in India. Recent studies show that the frequency of droughts is increasing. While droughts are known to cause severe rural distress, little is known on how gender influences the experiences of men and women in coping with droughts.
