Water quality is a missing puzzle piece to successful ocean conservation efforts, given its impacts on ocean health and public health. Roughly 80 percent of the world’s wastewater is discharged—untreated or only partially treated—into our lakes, rivers, streams, and the ocean.
The Water Quality Hub features resources to help the ocean conservation community make the important connections between water quality and the durability and success of many ocean conservation objectives—including fisheries health, the protection of marine habitats, coastal resilience, public health, and environmental justice. These resources are designed for new entrants and seasoned practitioners alike to better understand the vital connections between water quality and ocean health, promising solutions at hand, and opportunities for active engagement.
Explore ways to connect the dots between water quality and the success of ocean conservation initiatives.
This section includes an orientation on the threat of impaired water quality, interviews with thought leaders, insights from leading research studies, and frameworks for action. We encourage new entrants and seasoned practitioners alike to learn more and explore emerging insights from the field.
- Turning the Tide on Sewage Pollution in the UK: An Interview with Surfers Against Sewage
Surfers have long been on the frontline of sewage pollution as untreated wastewater is routinely pumped into coastlines in many parts of the world. Our Shared Seas spoke with Hugo Tagholm, the CEO of Surfers Against Sewage, to learn how the organization is working to end sewage pollution in the UK through data collection, campaigning, and public engagement.
- Key U.S. Water Wins in 2021 and What’s Ahead in 2022: An Interview with the Water Foundation
In 2021, civil society and the Biden Administration ushered in a game-changing era of water investments—the largest investment in our water and wastewater infrastructure since the passage of the Clean Water Act. Our Shared Seas sat down with Jen Sokolove of the Water Foundation to understand how philanthropy and NGO partners can help maximize those funds to benefit communities, freshwater, and coasts in 2022 and beyond.
- Unpacking Nature-based Solutions and Co-Benefits: A Primer
Nature-based solutions are increasingly entering the dialogue as an option to support climate mitigation and adaptation objectives while delivering co-benefits like pollution reduction and restored coastal habitat. This article describes the nuanced differences between nature-based solutions, green infrastructure, and blue carbon – and where these approaches may provide win-wins for people and planet.
- Innovative sewage solutions: Tackling the global human waste problem
Sewage and wastewater pollution directly impacts water quality and ocean health, but fortunately we have a toolkit of effective solutions at hand. This article from Mongabay recaps the landscape of affordable and scalable solutions, featuring insights from renowned experts.
- Seminal Study Maps Impacts of Wastewater on Coastal Ecosystems: An Interview with Dr. Ben Halpern
A new study is the first of its kind to map nitrogen inputs from wastewater pollution in 130,000 watersheds around the world. In this interview, Dr. Ben Halpern shares insights from the study to shed light on how to use these findings to prioritize management interventions and minimize tradeoffs for ocean health.
- Water Quality and Ocean Conservation: How Funders Can Engage
Water quality threatens to undermine the success of many conservation initiatives, but there are numerous ways that ocean funders can address this cross-cutting issue through their existing strategies. This article provides recommendations on ways funders can engage on water quality to achieve their objectives—whether related to small-scale fisheries and MPAs or public health and environmental justice.
- Why 30×30 Success Depends on Good Water Quality
As the global community devotes growing attention and resources to securing an agreement to protect 30 percent of the ocean by 2030, it has generally overlooked wastewater pollution as a threat to ecosystems. This primer explains how wastewater pollution is driving coastal water quality declines, including in existing MPAs, and what is needed to support efforts like 30×30.
- Holistic Management of Marine Ecosystems Must Include Water Quality: An Interview with Dr. Amelia Wenger
Our Shared Seas spoke with Dr. Amelia Wenger of the University of Queensland and Wildlife Conservation Society about how wastewater impacts coastal ecosystems and human health. Learn more about land-based threats, as well as how researchers, funders, and practitioners can work across silos to implement solutions now.
- Addressing Coastal Water Quality Improves Marine Conservation and Human Health: An Interview with Alison Bowden
Nutrient pollution from sewage and stormwater is a significant threat in many coastal environments and has crosscutting consequences on human health and ecosystems. In this interview, Alison Bowden of The Nature Conservancy explains how addressing coastal water quality can improve climate resilience, commercial fisheries, and livelihoods.
