Impact of Lake Recovery on Agricultural Ecosystem Services

Emissions from the combustion of fossil fuels in the Eastern US, has long been identified to acidify Nova Scotia lakes. However, due to a reduction in the use of high-sulphur fossil fuels, lakes are beginning to recover which is resulting in chemical and biological changes. In Nova Scotia, lakes are often relied on to provide nutrient cycling of domestic wastewater, and agricultural wastewater and run-off. However, it is unknown what effect lake recovery will have on nutrient cycling. Therefore, the objective of this research was investigate lake recovery in lakes influenced by agricultural practices. This research will help the agricultural community develop best management practices to ensure healthy and sustainable aquatic ecosystems.
