A study highlights the need to scale down the export of rice, maize, buffalo meat and other items to conserve groundwater in India.

The recent trade war between the United States and China was, among other things, about virtual water - the hidden water in products. Producing anything, whether it is soyabean or clothes, uses water, and has a water footprint. Even after production, shipping and trading also have a hidden water cost.

A study calls for solutions that can benefit farmers and the environment and positively impact India's nutrition indicators.

A new study finds that introducing coarse cereals such as millet and sorghum could improve India’s national food supply in many ways. The study by the Data Science Institute at Columbia University found that India’s agricultural policies have largely focused on the single objective of maximizing production, and not enough attention has been given to nutrition, climate, and environment.

A study highlights the barriers to harnessing India's potential for wind energy.

Wind energy is a renewable, inexhaustible, non-polluting and popular alternative source of clean energy. India stands fourth in the world in wind energy conversion and utilization, with an installed capacity of about 34,605 MW as of September 2018. Countries such as Uruguay, Germany and United Kingdom are meeting as much as 19.5%, 12% and 11% respectively of their electricity demand through wind power. China is a leading nation in wind power installed capacity and has grown rapidly, from 300 MW in 2000 to 188,232 MW in 2018.

A study finds that weak environmental assessment reporting on the adverse impacts of mining has spelled doom for Goa’s environment.

Development and its impact on the environment has long been a contentious issue in India, where lack of adequate monitoring and control mechanisms have led to severe degradation of land, water and forest resources. Mining activities in Goa have not only poisoned its land and water, but also affected livelihoods by negatively impacting agriculture, fisheries and forests.

A report by NIUA brings to light the chinks in Jaipur's sewage system and suggests some solutions.

A major area of concern currently for India is the proper disposal of wastewater in urban areas. The huge increase in supply of potable water to cater to the needs of modern urban households has correspondingly increased the quantum of wastewater. The implementation of the Swacch Bharat Mission has also led to a substantial increase in the number of toilets and this has increased the faecal sludge and the wastewater load considerably.

A study finds that India may run out of water to cool power plants in the near future.

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. Thermal power plants (e.g. natural gas, nuclear, and coal) use water for cooling. Water scarcity may reduce the availability of thermal power capacity and impede the ability to reliably provide the energy services that motivate addition of coal capacity.

Study points to vulnerabilities faced by women in the mountains and plains of Uttarakhand, which is likely to only increase with climate change.

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. Gender mainstreaming entails re-organising formal structures of decision making and institutional processes to acknowledge gender as a centrality, rather than as an add-on.
