The Professional Science Master’s in Ecosystem Science and Sustainability enables students from diverse academic backgrounds, such as environmental studies, business, engineering, natural resources, and agriculture, to understand the latest ecosystem science and develop the skills needed for emerging professions in areas such as greenhouse gas/carbon management, water sustainability and watershed management, and climate adaptation.

After completing the program, students will be able to:

  1. Evaluate linkages between socioeconomic and ecosystem processes that influence sustainability of carbon, water resources, and/or food management.
  2. Develop sustainable management strategies to maintain ecosystem processes related to carbon, water resources, and /or food management.
  3. Promote policies enhancing the sustainability of ecosystem related to carbon, water resources, and/or food management.
  4. Build, work within, and lead interdisciplinary teams in a professional environment.

Interested in exploring greenhouse gas policies, climate change science, and estimation of greenhouse gas footprints? Want to gain real-world experiences through a professional internship? Our program in carbon management leverages CSU’s world-leading greenhouse gas and carbon management expertise to prepare graduates for rewarding careers. Recent graduates work for institutions such as city and state governments, carbon registries, non-governmental organizations, environmental consulting firms, and other firms focused on solving the climate change challenge.

The watershed science track provides students with the skills needed to work as hydrologists and watershed managers across a broad range of sectors. Students explore fundamental concepts in watershed science, emerging field methods, computational analysis, impacts of land-use and land cover change, and effective watershed management in the face of environmental change. Students can focus on various important areas of watershed science that will prepare them for careers as federal hydrologists, municipal watershed managers or water sustainability officers, or work in the field of environmental consulting and river/watershed restoration. The program leverages departmental and campus-wide expertise in hydrologic and watershed science and harnesses the long history of watershed science at Colorado State University.

The sustainable food systems track provides students with the skills needed to analyze and promote sustainability across food supply chains. Students explore sustainable agriculture, interdisciplinary perspectives on food systems, and the relationships between climate change and food, in addition to gaining real-world experiences through professional internships. CSU is a land grant university with a long history of world-leading expertise on food systems, with a substantial campus-wide focus on promoting resilient and sustainable food systems in Colorado and around the world.
