Judgement of the National Green Tribunal in the matter of Manoj Misra & Others Vs Art of Living International Center & Others dated 07/12/2017 regarding World Culture Festival Celebration on Yamuna flood plain. This has led to illegal and unauthorized dumping and construction in the active flood plains of river Yamuna in the NCT of Delhi which was taking place over some 25 hectares upstream of DND Flyway. The flood plains which were excellent natural wetlands as recently as September 2015 have been cleared and levelled by the Art of Living International Center.

A critical question for agricultural production and food security is how water demand for staple crops will respond to climate and carbon dioxide (CO2) changes, especially in light of the expected increases in extreme heat exposure. To quantify the trade-offs between the effects of climate and CO2 on water demand, we use a ‘sink-strength’ model of demand which relies on the vapour-pressure deficit (VPD), incident radiation and the efficiencies of canopy-radiation use and canopy transpiration; the latter two are both dependent on CO2.

Global warming is expected to intensify the Earth’s hydrological cycle and increase flood and drought risks.

Judgement of the National Green Tribunal (Eastern Zone Bench, Kolkata) in the matter of Tenzing Lepcha & Others Vs Ministry of Environment and Forests & Others dated 15/11/2017 regarding Teesta-IV Hydro-Electric Project on the Teesta river near Chandey Village on left bank and near the Gyathang Village on the right bank in North district of Sikkim. The project envisages construction of a 65m high concrete gravity dam across Teesta river in downstream of confluence of Runchu with Teesta for a generation of 520 MW hydropower.

Judgement of the Supreme Court of India in the matter of National Institute of Medical Science University Rajasthan & Others Vs State of Rajasthan & Others dated 09/11/2017 regarding water shortage in Jaipur city and the drying up of Ramgarh Lake. The case deals with the massive encroachments in the catchment areas of Ramgarh Dam especially by the National Institute of Medical Sciences University or NIMS.

Order of the National Green Tribunal in the matter of Pratiba Naitthani Vs. Union of India & Others dated 07/11/2017 regarding Gauri Kund spring near Kedarnath in the Himalayan Range in the State of Uttarakhand.

NGT directs the State of Uttarakhand and CGWA to make every effort to restore the hot spring which had been destroyed in 2013 during a natural calamity.

Developing countries around the world are expanding hydropower to meet growing energy demand. In the Brazilian Amazon, >200 dams are planned over the next 30 years, and questions about the impacts of current and future hydropower in this globally important watershed remain unanswered. In this context, we applied a hydrologic indicator method to quantify how existing Amazon dams have altered the natural flow regime and to identify predictors of alteration.

Judgement of the National Green Tribunal (Eastern Zone Bench, Kolkata) in the matter of Biswajit Mohanty Vs State of Odisha & Others dated 16/10/2017 regarding construction activity and reclamation of river bed, encroachment of river embankment, establishment of Labour Camps in river bed of rivers Mahanadi and Kathjodi at Cuttack, Odisha, and organization of Baliyatra and other programmes on Mahanadi river bed at Cuttack thereby affecting the river ecology and disturbing the river flow adversely.

Recent studies have shown an increasing trend in hydroclimatic disturbances like droughts, which are anticipated to become more frequent and intense under global warming and climate change. Droughts adversely affect the vegetation growth and crop yield, which enhances the risks to food security for a country like India with over 1.2 billion people to feed.

Glaciers in the high mountains of Asia (HMA) make a substantial contribution to the water supply of millions of people, and they are retreating and losing mass as a result of anthropogenic climate change3 at similar rates to those seen elsewhere. In the Paris Agreement of 2015, 195 nations agreed on the aspiration to limit the level of global temperature rise to 1.5 degrees Celsius ( °C) above pre-industrial levels. However, it is not known what an increase of 1.5 °C would mean for the glaciers in HMA.
