The Crow Soil Ecology & Biogeochemistry Research Group in the Natural Resources and Environmental Management Department at the University of Hawaii Manoa 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.

Research Interests

  • Mechanisms of soil organic matter stabilization and destabilization
  • Sources and sinks of terrestrial carbon
  • Greenhouse gas flux and nutrient status
  • Improved practices in agroecosystems
  • Soil Health and climate change mitigation ecosystem services
  • Systems-level carbon economy
