The Earth Science Women's Network, Association for Women Geoscientists and the American Geophysical Union are partnering to address the problem of sexual and other types of harassment and other exclusionary behaviors, such as bullying, discrimination and identity-based aggressions, that lead to hostile working and learning environments in the earth, space and environmental sciences with a four-year, $1.1 million grant from the National Science Foundation ADVANCE program. A primary goal of the project is to improve workplace climate conditions by developing bystander intervention education for department heads, chairs, faculty and grad students to appropriately respond to and prevent harassment, bullying and other exclusionary behaviors in research environments.
