This paper briefly synthesizes recent research illustrating how smartphones, sometimes in conjunction with other sensors, present a nexus point method for citizen scientists to engage with and use sophisticated modern technology for water quality monitoring.

A mounting global water crisis threatens $58 trillion in economic value, food security and sustainability, according to this new report by the World Wide Fund for Nature (WWF).

Today at the half-way point for the SDGs, UNEP is preparing to provide important intelligence on the progress we are making on the environmental dimension. The latest available data and estimates for 92 environment relevant SDG indicators tell us that the world is not on track to achieve the environmental dimension of the SDGs by 2030.

The Asia-Pacific region has made considerable progress on improving economic and social welfare over the last decade.

Maintaining the state or health of rivers is a vital part of sustainable development. Healthy rivers are able to support and maintain key ecological processes and thus ecosystem services on which society depends.

Western Africa is rich in freshwater biodiversity and regional endemicity, supporting the entire global populations of many threatened freshwater species including fishes, molluscs, dragonflies, crabs, shrimps and aquatic plants.

Target 6.6 is: “By 2020, protect and restore water-related ecosystems, including mountains, forests, wetlands, rivers, aquifers and lakes.” Indicator 6.6.1 tracks changes over time in water-related ecosystems. Earth observations are used to determine changes to surface water bodies, such as lakes, large rivers, flooded wetlands and reservoirs.

Use of coastal, estuarine and freshwater recreational environments has significant benefits for health and well-being, including rest, relaxation, exercise, cultural and religious practices, and aesthetic pleasure, while also providing substantial local, regional and national economic benefits.

More than 8,000 million metric tons of plastic have been made since the beginning of large-scale plastic production in the 1950s. As a consequence, plastic debris is present in all ecosystems, including remote locations such as mountain lakes and polar sea ice.

To launch the UN Decade on Ecosystem Restoration, UNEP has released this synthesis report as a call to action for anyone and everyone to join the #GenerationRestoration movement to prevent, halt and reverse the degradation of ecosystems worldwide.
