Project description
Predicting the impact of salinisation on N20 emissions
Freshwater salinisation from urbanisation, agricultural runoff, and climate change is expected to disrupt key nitrogen cycling processes, particularly nitrification and denitrification, which contribute to N2O emissions. Current lake models do not effectively account for N2O production or the effects of salinisation on it. Supported by the Marie Skłodowska-Curie Actions programme, the SALTY-N project explores how rising salinity in freshwater ecosystems affects N2O emissions. It will develop an enhanced nitrogen reaction module for the CE-QUAL-W2 model and test it in Lake Wilcox, Canada, and Lake Lannenec, France. The project aims to develop a tool to predict the impact of salinisation on N2O production, informing climate policies and environmental management strategies.
Objective
The SALTY-N project aims to uncover how rising salinity levels in freshwater ecosystems influence nitrous oxide (N2O) emissions, a potent greenhouse gas contributing to global climate change. Freshwater salinization, driven by urbanization, agricultural runoff, and climate change, is expected to disrupt nitrogen cycling processes, specifically nitrification and denitrification, which are key sources of N2O. Current lake models do not adequately account represent N2O production and emissions and lack the potential to predict the impact of salinization on N2O production. SALTY-N will address this gap by developing an enhanced N reaction network module and integrating it into the widely used, open-source, CE-QUAL-W2 model. This model will be tested in two lakes, with distinguished sources of salinization—Lake Wilcox in Canada where increasing salinity is related to urbanization and use of the winter road salt, and Lake Lannenec in France that is subject to sea water intrusion—through field campaigns, laboratory experiments, and advanced biogeochemical simulations. The project will assess how salinity alters microbial N transformations and their contributions to N2O production, producing a transferable and opensource tool for researchers and water managers to predict the effects of freshwater salinization on N2O production. The findings will help inform future climate policies and environmental management strategies aimed at reducing greenhouse gas emissions from freshwater systems, directly addressing the priorities of the policy makers on climate change mitigation and ecosystem preservation.
