World Water Day 2022

World Water Day is on 22 March every year. It is an annual United Nations Observance, started in 1993, that celebrates water and raises awareness of the 2 billion people currently living without access to safe water. A core focus of World Water Day is to inspire action towards Sustainable Development Goal (SDG) 6: water and sanitation for all by 2030.

This year’s theme is ‘groundwater’ and draws attention to the hidden water resource that has always been critically important but not fully recognized in sustainable development policymaking. Groundwater is invisible, but its impact is visible everywhere. Out of sight, under our feet, groundwater is a hidden treasure that enriches our lives. Almost all of the liquid freshwater in the world is groundwater. As climate change gets worse, groundwater will become more and more critical.  We need to work together to sustainably manage this precious resource. Groundwater may be out of sight, but it must not be out of mind. 

To raise awareness on sustaining groundwater, Elsevier presents a curated list of publicly available journal articles and book chapters. At Elsevier, we are advancing #SDG6 research and ensuring that #groundwater is sustainably explored, analyzed, and monitored.

A right to clean water is one of the global SDGs and is especially important for women.

The Lancet Global Health, Volume 9, March 2021

This Viewpoint supports SDGs 3, 6, and 7 by discussing some of the reasons why many of the innovations and technologies for WASH (water, sanitation, and hygiene) and household air pollution developed in recent decades have not led to the expected improvements in health outcomes, and why many of these interventions have either been inconsistently adopted by low-income households, or not adopted at all.

Physics and Chemistry of the Earth, Volume 122, June 2021

This article discusses the radiological safety of groundwater around a uranium mine in Namibia.

Water Resources and Economics, Volume 33, January 2021

This study analyzes the effects of a local water market formation on the efficiency of groundwater use productivity. These results demonstrate the role of a market-based groundwater allocation approach under water scarcity conditions.
Various microorganisms as a source of green technology used for bio-inspired wastewater treatment (WWT).
Elsevier, Current Research in Green and Sustainable Chemistry, Volume 5, January 2022
Overuse of water has led to the degradation and scarcity of limited water resources, which prompted the modern world to adopt sustainable measures to save water by increasing its reuse and recycling. The use of microbial-based green technology to treat wastewater has appeared to outweigh conventional wastewater treatment (WWT) technologies because this emerging technology overcomes many of the shortcomings of conventional treatment systems.

The Lancet Planetary Health, Volume 6, January 2022

This Personal View supports SDGs 3 and 6 by suggesting a scale-specific approach in which agricultural water use is embedded in a larger systems approach to allow the design of effective incentives to change and optimise agricultural water use.
