In this course, we critically examine gender in environment and development. We review the process of gender mainstreaming, we analyze its historical challenges, and we propose innovative frameworks to better address these challenges. Using gender case studies, we take on the most pressing environment and development issues including: food security, climate change, and environmental justice. Furthermore, we apply our new knowledge to policy and programming. This class is relevant to students and professionals working in education, research, programming and policy who want to deepen their understanding of gender and to acquire tools to address gender in environment and development.
