Welcome to the Global Environmental Change Lab at UC Davis
Our Lab brings together high school and undergraduate interns, graduate students and early career researchers to conduct interdisciplinary research to better understand the drivers and consequences of global environmental change. We explore novel methods to examine the interactions between the human and Earth systems, relying on a variety of approaches, including the development and use of process-based models, empirical/statistical data-driven models and observational data analysis.
We are specifically interested in examining the impacts of climate and weather extremes and of management practices on various sectors of the economy and on ecosystems services. Our research has three major areas of focus: 1) the land system, including agriculture, forest productivity and health, wildfires, and biodiversity; 2) the interaction among climate, air quality and human health; and 3) the impacts of global environmental change on the global biogeochemical cycles.
Our goal is to identify and understand the role of key stressors on the environment and society in order to provide actionable information to support effective and efficient adaptation strategies. Through a better understanding of the dynamics between the human and Earth systems, we aim to identify and evaluate adaptation strategies to better support decision making to ensure a resilient, equitable, sustainable and prosperous world.
