Welcome to Legacies of Agricultural Pollutants

Human activities have greatly accelerated the nitrogen (N) and phosphorus (P) cycles, with excess N and P leaching into surface and groundwaters, causing problems of eutrophication, aquatic toxicity and drinking water contamination.

Protecting water quality in the face of a growing population and the corresponding demands on agriculture is critical to ensuring both water and food security for generations to come.

Legacies of Agricultural Pollutants (LEAP) is going to develop a unified framework that incorporates agricultural legacies and time lags into adaptive management strategies to protect water resources under changing climate and land use.
