Bella Mayorga, Lead Project Manager

Bella graduated from the University of California, Santa Barbara with a Bachelor of Science in Environmental Studies in 2019. As an undergraduate, she also completed a research project at UC Santa Cruz studying the local and landscape drivers of urban bird diversity and abundance in community-managed gardens of coastal California. In 2021, Bella graduated from the School for Environment and Sustainability at the University of Michigan with a dual-track masters degree in Geospatial Data Science and Ecosystem Science and Management. Her graduate thesis included synthesizing ecosystem service and biodiversity data from coffee farms in Puerto Rico as part of a study evaluating the tradeoffs and synergies associated with agroforestry management.  Prior to starting with SAGE, she worked for the San Francisco Bay National Estuarine Research Reserve (NERR) as the lead and coordinator of the education sector.

Bella’s broad interests in sustainability include habitat restoration, wildlife conservation, food systems, urban ecology, and renewable energy systems. She believe that sustainability is inherently rooted in social justice and that lasting environmental protection cannot be achieved independently of support  from local communities. In her free time, she enjoys rock climbing, running, redesigning second-hand clothing, and plant-based cooking.
