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.

Land Use Policy, Volume 109, October 2021

In an urbanized catchment, land use has a strong effect on water quality. The majority of the landscape metrics are correlated with Ave River Basin water quality. Water quality is dependent on landscape planning. Ave River Basin requires landscape intervention to restore hydric resources.

This study supports SDGs 3 and 6 by analysing data from 88 low-income and middle-income countries and showing geographical disparities in access to clean water and sanitation facilities. These findings identify where efforts to increase access to safe water and sanitation have been successful over time, and highlight the need for targeted and tailored interventions to reach those communities and regions that have been left behind.

Both subterranean rivers and groundwater sources can offer considerable contributions towards potential summer cooling of London Underground stations, while also having significant environmental and economic advantages relative to alternative refrigeration techniques.

Progress in Disaster Science, Volume 8, December 2020

This paper presents challenges for water security in the three largest riverine islands in Asia, a socio-hydrology approach to manage water scarcity and human well-being, and an adaptive management cycle to implement socio-hydrology in the field.

Development Engineering, Volume 7, January 2022

By analyzing the impact of both public water supply and water handling containers, this paper makes an important contribution to the literature regarding the effectiveness of water supply programs based on the following related outcomes: objective and subjective water quality at the source and Point-of-use (POU), POU water treatment, water transport and storage behavior, and uptake of new, improved water points.

This study supports SDGs 3 and 6 by showing that an integrated WASH (water, sanitation, and hygiene) intervention alone was not successful in preventing transmission of trachoma in rural Ethiopia. These findings conclude that, in areas with hyperendemic trachoma, WASH interventions need to be combined with mass distribution of antibiotics (azithromycin) in order to successfully eliminate trachoma.

In this study, the authors investigate the effect of phosphate functionalisation on the removal of uranyl ions from mine-drainage contaminated water.

This study supports SDGs 3 and 6 by investigating a low-cost behavioural intervention designed to increase latrine use and safe disposal of child faeces in India. The study found the intervention modestly increased latrine use and markedly increased safe disposal of child faeces in the short term, but was unlikely to reduce exposure to pathogens to a level necessary to achieve health gains.
