Earth Day 2025

22nd April is Earth Day, an annual, global movement to raise awareness and promote environmental protection. The theme for Earth Day 2025 is OUR POWER, OUR PLANET, inviting everyone around the globe to unite behind renewable energy, and to triple the global generation of clean electricity by 2030. To mark the event Elsevier has curated a free to access Special Collection featuring the latest research articles and book chapters to advance knowledge.

Supported by Dubai Cares and together with Unbounded Associates and Plan International, the Ban Ki-moon Centre presents the “

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. 

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.
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.
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
