Excess nutrient inputs and climate change are two of multiple stressors affecting many lakes worldwide. Lake Vansjø in southern Norway is one such eutrophic lake impacted by blooms of toxic blue-green algae (cyanobacteria), and classified as moderate ecological status under the EU Water Framework Directive. Future climate change may exacerbate the situation.
In response to water crises across the globe, data on biophysical conditions associated with water risk have increasingly been collected and understood. However, a complete assessment of water risk also requires an understanding of public water management.
