Research Interests

Paul Withers is Professor of Geography at Bangor University with research interests in sustainable nutrient use, nutrient accounting, catchment science and landscape management. His main research focus has been understanding phosphorus cycling in terrestrial and aquatic ecosystems, processes of phosphorus transfer across the land-water interface, eutrophication impacts of different phosphorus sources and associated mitigation strategies. Two major current projects are the development of strategies to improve the sustainability of phosphorus use in arable farming and understanding the coupling of C, N and P along the freshwater-estuarine continuum and links to eutrophication control.

He is a regular keynote speaker with over 60 peer-reviewed publications and an h index of 25.
