NREM691 Quantitative Ecosystem Carbon


In the Soil Ecology and Biogeochemistry Lab, we study carbon dynamics and sequestration, greenhouse gas flux, nutrient and water management in natural and managed (forested or agriculture) ecosystems and how these relate to global change pressures - such as land-use, climate change, and invasive species - sustainable agriculture, and renewable energy production. We pursue mechanistic understanding of ecosystem processes to tackle tough questions relevant to current environmental issues. At the systems-level, we quantify and model the carbon tradeoffs of renewable fuel systems and integrate across disciplines of economics, engineering, and agroecology to build resilience into our society against uncertainty in the climate system, energy, and water accessibility. Through the Soils&EcoSystems Service Lab, we provide collaborators and researchers with plant, soil, and water analyses.
