Land ecosystems and land use change
Terrestrial ecosystems and their services are key elements of the climate system and global biogeochemical cycles, but are rapidly changing due to urbanization, climate change, and the high demand for food, fiber, and bioenergy. ESS researchers use observations, field experiments, and model simulations to study land-atmosphere interactions, ecosystem-climate feedbacks, and human impacts on the integrity of terrestrial ecosystems. Our group aims to identify tipping point elements in Earth’s biosphere-climate-human systems and to promote more sustainable use, management, and conservation of natural and anthropogenic ecosystems.
