Phosphorus and Climate Change: A Vicious Circle
Global freshwater is now believed to be a major source of greenhouse gas emissions to the atmosphere. Around the world, phosphorus-driven freshwater eutrophication drives increased primary productivity and thus increases organic matter available for decomposition and consequent greenhouse gas emissions. In turn, greenhouse gases drive climate change, leading to increased phosphorus, nitrogen, and sediment transport from land to water by amplifying runoff and erosion. We will explore the links between climate change and phosphorus and highlight some emerging technological approaches deployed in North America and Europe to disrupt this ecologically destructive feedback loop.
