World Water Day, held on March 22, is an annual United Nations Observance focusing on the importance of fresh water. The theme of this year’s observance is Glacier Preservation; glaciers are critical to life – their meltwater is essential for drinking water, agriculture, industry, clean energy production, and healthy ecosystems. To mark World Water Day 2025, Elsevier has curated a free special collection of journal articles and book chapters to raise awareness for this important topic, and to help advance #SDG6 research.

Massimiliano, Rosa-Clot & Tina, Progress in Floating Photovoltaic Systems, 2025, Pages 1-23

This chapter supports SDGs 7, 11, and 13, by providing an overview of floating photovoltaics as a major segment within photovoltaics, reviewing the current situation and future potential of floating PV as a key area of solar energy.

This paper considers the human health risk associated with the presence of aluminium in drinking water treated with aluminium-based coagulants in a rural area of Ecuador.

Also in laboratories we should be critical about the amount of water, energy, and resources used. There is room for increasing efficiency and better mangement there as well. The objective of this study is to evaluate the carbon and water footprints present in an environmental laboratory..

The authors demonstrate that Explainable Artificial Intelligence (XAI) enhances transparency in water systems through interpretable decision-making models. XAI supports policymakers by providing climate impact insights for urban drainage systems. A number of key water management challenges can be addressed with XAI.
IoT technologies are a powerful tool for large-scale water distribution systems, this survey highlight the key challenges such as interoperability, scalability, and energy efficiency. It proposes a framework that combines water network analysis, wireless network simulation, and optimization algorithms to enable sustainable and efficient deployment of massive IoT in water distribution systems
Per and polyfluoroalkyl substances (PFAS) are persistent synthetic chemicals with strong carbon-fluorine (C-F) bonds, making them resistant to environmental degradation. Their widespread presence in groundwater, surface water, and drinking water, is a serious environmental threat. This artciles demonstrates the potential of novel adsorbents to achieve high PFAS removal rates while minimizing secondary contamination risks.

Prioritizing green and water-conscious production, making the energy transition more sustainable via water-conscious and green production of hydrogen and methanol.

This study demonstrates that aerobic exercise, specifically swimming training, improves learning and memory in Alzheimer's disease model mice by enhancing glymphatic system function and promoting AQP4 polarization, which facilitates clearance of β-amyloid in the hippocampus. These findings suggest that exercise-induced upregulation of Lama1 and Dp71 supports glymphatic clearance mechanisms, thereby reducing Aβ deposition and cognitive impairment.
This study examined perceptions and awareness of brain health among Cuban youth through an online survey of 1,049 participants using the Global Brain Health Survey. Results showed that participants viewed the social environment as the most influential factor on brain health and were generally aware of conditions like Alzheimer’s and depression, but had limited understanding of the cognitive effects of chronic diseases such as hypertension and diabetes, underscoring the need for targeted public health education and awareness campaigns.
