Nutrient flows form the bedrock of ecosystem functioning, and support many of the ecosystem services that support human societies. Many of these flows have been profoundly and geographically altered by human activity, contributing to rapid global environmental change and growing recognition that we may have entered a new geologic epoch – the Anthropocene. Yet the concept of the Anthropocene is both a challenge and an opportunity, serving as an omen for the peril of human impacts on the Earth system and as a sign of hope through the embrace of new interventions in nutrient flows that can build a more resilient and sustainable future.
This session examines nutrient geographies in the context of the Anthropocene. Possible topics include, but are certainly not limited to: N and C cycles in unmanaged ecosystems as altered by fire, climate, and/or atmospheric deposition; agriculture-induced changes to N, P, and C cycles and multi-scale approaches to farm management; the impacts of non-point-source pollution on ground, surface, and coastal waters; agroecological interventions in nutrient flows; nutrient geographies and the metagenomics revolution; nutrient flows in urban spaces; and nutrient geographies in a teleconnected world.
