At UC Berkeley's Rausser College of Natural Resources, we study natural and human systems from biological, ecological, economic, and social science perspectives. With more than 120 faculty and approximately 1,800 undergraduate and 300 graduate students, we engage the issues that shape the complex, interconnected world of the 21st century, from sustainable food systems to obesity, from water policy to energy policy, and from the far-reaching impacts of climate change to the linkages between the human genome, diet, and disease.
