Urban water demand will increase by 80% by 2050, while climate change will alter the timing and distribution of water. Here we quantify the magnitude of these twin challenges to urban water security, combining a dataset of urban water sources of 482 of the world’s largest cities with estimates of future water demand, based on the Intergovernmental Panel on Climate Change (IPCC)’s Fifth Assessment scenarios, and predictions of future water availability, using the WaterGAP3 modelling framework. We project an urban surface-water deficit of 1,386–6,764 million m³.

To chalk out the future course of action in view of the disputes regarding the use of Mahanadi river water, a well-rounded strategy that includes both the people and policymakers is needed. The strategy must allow for dialogue by rebuilding trust and should look at arbitration and negotiation as methods of conflict resolution.

Order of the National Green Tribunal in the matter of Rear Admiral AP Revi IN (Retd.) Vs. Delhi Jal Board & Others dated 26/10/2017 regarding use of fresh water for gardening purpose in Vasant Kunj area of Delhi. NGT passes direction that DDA/MCD shall ensure that DJB shall supply treated sewage water for gardening at the fixed rate which will be the primary responsibility of the public authority. The residents, DDA/MCD and DJB are prohibited to use fresh water for gardening purpose.

Water scarcity is rapidly increasing in many regions. In a novel, multi-model assessment, we examine how human interventions (HI: land use and land cover change, man-made reservoirs and human water use) affected monthly river water availability and water scarcity over the period 1971–2010. Here we show that HI drastically change the critical dimensions of water scarcity, aggravating water scarcity for 8.8% (7.4–16.5%) of the global population but alleviating it for another 8.3% (6.4–15.8%).

It is often purported that unusually dry weather conditions provoke small-scale social conflict—riots—by intensifying the competition for water. The present paper explores this hypothesis, using data from Sub-Saharan Africa. We rely on monthly data at the cell level (0.5×0.5 degrees), an approach that is tailored to the short-lived and local nature of the phenomenon. Using a drought index to proxy for weather shocks, we find that a one-standard-deviation fall in the index (signaling drier conditions) raises the likelihood of riots in a given cell and month by 8.3%.

Indiscriminate Withdrawal Of Groundwater Means India May Run Out Of Its Supply Of Usable Water In A Few Years

Murang’a town residents will benefit from a Sh3 billion water storage programme to be initiated by Murang’a Water and Sanitation Company.

Order of the Supreme Court of India in the matter of State of Karnataka Vs State of Tamil Nadu & Others dated 21/03/2017 regarding Cauvery water dispute. The basic prayer in these interlocutory applications is that the State of Kerala should not utilize the water more than that has been allocated to it by the award under challenge and also to stop certain constructions (check dams).

The Tamirabarani river is a part of the ecological and cultural landscape, and traditions of the people of Tamil Nadu. Unfortunately, public resources like the river water are sold at throwaway prices to corporations, who in turn resell the water either in the form of packaged drinking water or as aerated beverages. The political economy of the river and the state’s industrial plans, require radical rethinking.

In this paper, the term multi-purpose water infrastructure (MPWI) encompasses all man-made water systems, including dams, dykes, reservoirs and associated irrigation canals and water supply networks, which may be used for more than one purpose (for economic, social and environmental activities).
