The Graduate Environmental Studies Student Association (GESSA) is the student-run organization for graduate students in FES, and is an associate member organization of the Graduate Students' Association (GSA) at York. All graduate students are members of GESSA and are entitled to the use of its resources and services.
The Executive coordinates the general activities of the association and provides information on faculty policy issues and events to the student body. Members also act as liaisons between faculty and students as needed. Elected delegates (elections take place in January each year) represent MES and PhD students on various FES committees and at other levels of governance on campus, such as the Graduate Students' Association. GESSA holds general meetings at which students are encouraged to participate and share ideas.
GESSA sponsors various student run programs such as Undercurrents, an environmental journal, and the Maloca Community Garden, located in the southwest corner of the York University campus. Each semester, GESSA also sponsors social events and other community building activities. Funding for conferences and research are available through both the GESSA Research and Travel Fund and the GSA.
