The document discusses the CEECEC project and EJOLT project, which aim to teach ecological economics and political ecology concepts to environmental NGOs. It describes how NGOs can inform academic concepts through case studies, and how academic concepts like "ecological debt" have informed activist movements. It summarizes several case studies from the CEECEC project handbook that examine topics like mining, waste management, and protected areas from an ecological economics perspective. It also discusses how the concept of "degrowth" has moved from activist movements to academic research on transitioning to a steady-state economy in a socially and environmentally sustainable way.
