Helen Jarvie is a Professor of Water and Global Environmental Change at the University of Waterloo, Canada. She holds adjunct and visiting professor positions at the University of Arkansas (Fluvial Sciences), Plymouth University (Environmental Chemistry), and the University of Tokyo (Water Quality Science), and is a UK Centre for Ecology & Hydrology Fellow.
Her research centers on river-system biogeochemistry, with intense focus on nutrient (phosphorus and nitrogen) cycling, eutrophication, and water quality across watershed-to-global scales. She investigates how climate variability, land-use change, and human activities drive water-quality impairment, and develops strategies for improved nutrient stewardship to build resilience in water resources. Her work uniquely bridges the critical tension between phosphorus-dependent food security and water-quality protection, given phosphate rock's non-renewable status.
Analysis of her 2015-2019 publications reveals dominant trends in phosphorus dynamics research, spanning watershed management, global phosphorus budgets, and the water-energy-food nexus. Key themes include unintended consequences of agricultural conservation practices on soluble phosphorus loads, stoichiometric responses to hydrologic extremes, and sustainable phosphorus stewardship frameworks addressing eutrophication while ensuring resource security for future food production.
