Environmental Impact

A partnership which helps protect freshwater ecosystems by shaping Government policy has adopted an innovative approach to sustainable water management.

Protecting river ecosystems

WW and Durance 2

A long-standing collaboration between Cardiff University, Welsh Government and Dŵr Cymru Welsh Water (DCWW) has harnessed Cardiff’s research expertise to develop new ways of managing waters and catchments.

Led by Professor Isabelle Durance, School of Biosciences, an interdisciplinary Cardiff team measured and modelled variation in river ecosystems to show how future land use changes and climate change can affect freshwater biodiversity.

The researchers  developed a full understanding of the link between catchment management, river biodiversity and the sustainability of services that healthy freshwater ecosystems can provide, such as clean water or fish.

Cardiff’s long-term expertise and datasets were key to lead the freshwater component of the Biodiversity and Ecosystem Service Sustainability (NERC-BESS, 2011-2017) strategic programme – the first national research programme of its kind in the world.

Cardiff led the £3.1m Diversity in Upland Rivers for Ecosystem Service Sustainability (DURESS) project (2012-15), tasked to quantify the ‘missing link’ between landscape decisions, river biodiversity and sustainability.

Professor Durance and the Cardiff University team are now supporting the business on a wide range of research and other projects. Specifically they are supporting our catchment management work targeting both improved water quality, biodiversity, sustainable land management and developing nature-based solutions.

Political change

The partnership also informed DCWW’s decision to launch the Beacons Megacatchment Partnership to work with upland land managers on a nature-based approach to improving water quality in the National Park area which supplies almost half the company’s water.

We are delighted the work of Professor Durance and her team is being recognised by the University. The research work, tools and techniques developed by Cardiff allowed Wales to adopt an ecosystem services approach at the heart of the Environment (Wales) Act, putting Wales at the forefront of environmental legislation in the UK.

The holistic ecosystem approach – and the set of tools and concepts gathered – have helped inform government policies such as the Environment (Wales) Act 2016. The Cardiff research has also been adopted internationally. It played a significant role in the establishment of the Cubango-Okavango River Basin Fund, an independent $250m fund to enhance livelihoods, improve ecosystem resilience and provide equitable benefits to the countries who share this unique UNESCO site
