On April 22 every year, we celebrate the anniversary of the birth of the modern environmental movement with Earth Day.

The predicted future climate change can be expected to have an impact on the biogeochemical conditions in pit lakes that must be considered when modelling pit lake water quality. Climate change might e.g., affect temperature and precipitation patterns, which can influence other factors such as water balance, hydrology, limnology, and biogeochemical prediction

World Water Day is on 22 March every year. 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. 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

This article demonstrates that, by actively engaging in the interdependent phases of recognizing hybridity, enabling conditions for reflexivity and partnership building, 'inclusivity' tensions can not only be acknowledged but softened and, in some cases, reframed when managing for biodiversity, equity, and justice goals.

This chapter aligns with Goal 14: Life Below Water and Goal 12: Responsible Consumption by providing an overview of marine plastic waste and policy options to promote a circular plastic economy.

This chapter aligns with Goal 6: Clean water and sanitation and Goal 14: Life below water by arguing that further steps for the optimal management of MPAs should aim to improve the efficiency of the whole plastic waste management cycle, thus preventing and reducing debris entering the marine environment.

Temperature and sea level rise threats to aquaculture were the main focus in science and the news. At least 10 countries linked current impacts on aquaculture to climate change. Global papers cited technology for adaption, while regional papers cited governance.

Links to SDG6 and the theme of WWD as it covers the presence of emerging pollutants in aquatic systems such as rivers, lakes, groundwater, glaciers, wetlands, the ocean poses significant risks to human and environmental health.

This chapter aligns with Goal 14: Life Below Water and Goal 12: Responsible Consumption by discussing threats to the Franciscana dolphin and exploring novel options to reduce harmful bycatch.

This chapter aligns with Goal 14: Life Below Water and Goal 12: Responsible Consumption by highlighting the many marine pollution risks associated with ocean extraction/consumption and impacts to marine ecosystems.
