The “Green” rhetoric is constantly gaining traction in urban planning research. In line with anthropocenic thinking, the study of green cities and infrastructures has promised a straightforward recipe to solve many urban issues (e.g., climate mitigation and resilience, urban health, etc.). However, green city/infrastructure proponents, while emphasizing the positive environmental, economic, and health aspects of these projects, often neglect important socio-political and spatial considerations that are crucial for understanding the dramatic transformation of non-urbanized and peri-urban territories. Based on my latest research on urban megaprojects in Johor, Malaysia, and Doha, Qatar, in this paper I will critically re-discuss the green city/infrastructure idea by analyzing megaprojects’ biogeophysical and social displacements in peri-urban territories in the global South.
