The 2015/2016 El Niño event caused severe changes in precipitation across the tropics. This impacted surface hydrology, such as river run-off and soil moisture availability, thereby triggering reductions in gross primary production (GPP).

Order of the Supreme Court of India in the matter of M. C. Mehta Vs Union of India & Others dated 25/09/2018 regarding Taj Trapezium Zone. Meenakshi Dhote, Professor of Environmental Planning, DSPA and Project Coordinator of Vision Document for Taj Mahal stated before the Court that the suggestions received are being tabulated and analyzed and asked for the extension of the time to prepare the vision document till 15/11/2018.

Judgement of the National Green Tribunal in the matter of Bijay Krishna Sarkar & Others Vs Inland Waterways Authority of India & Others dated 14/09/2018. In this Original Application the applicant has sought relief and compensation for the damages caused to river Ganga and its aquatic life by hydraulic structures at Uttrakhand, Uttar Pradesh and West Bengal which has resulted into loss of the livelihood to the fisherman.

Order of the National Green Tribunal in the matter of B. Raghupathy Vs Union of India & Others dated 21/08/2018 regarding M/s. New Ark Project proceeding with a project without mandatory requirement of environmental clearance. The project consists of high-rise residential apartments and a commercial complex. The project involves extraction of ground water, generation of waste, generation of effluents, pollution of water streams, adverse population density and increased vehicular emissions. The project is in the catchment area of Bellandur and/or Varthur Lakes.

Hydropower is a valuable renewable energy resource in India, which can help in climate change mitigation and meet the increasing energy demands. However, the crucial role of climate change on hydropower production in India remains unexplored.

In summer (pre-monsoon) of recent years, low water level among the last few decades, has been observed in several lower Indian reaches of the Ganges (or Ganga) river (with estimated river water level depletion rates at the range of −0.5 to −38.1 cm/year between summers of 1999 and 2013 in the studied reaches).

The SIWI/SWH Cluster Group on Water in the Landscape has examined how hydrology affects the productivity of landscapes, and what hydrological aspects need to be considered when restoring landscapes for sustainable production.

To provide a picture of hydrological impact of climate change across different climatic zones in Europe, this study considers eight river basins: Tagus in Iberian Peninsula; Emån and Lule in Scandinavia; Rhine, Danube and Teteriv in Central and Eastern Europe; Tay on the island of Great Britain and Northern Dvina in North-Eastern Europe.

This paper presents future climate and runoff projections for the South Asia region under the RCP8.5 scenario with climate change informed by 42 CMIP5 GCMs. Runoff is projected for 0.5° grids using hydrological models with future climate inputs obtained by empirically scaling the historical climate series.
