This course provides the foundational knowledge for the study of political economy and political ecology from a historical, critical, interdisciplinary, global and Earth system perspective. It covers key literature, paradigms, theories, concepts, debates and topics in political economy and political ecology in relation to fields such as environmental, Earth system and climate change studies, critical development and postdevelopment studies, environmental geography, subaltern history, feminist, decolonial, and Global South paradigms, ecological economics, among others. As a foundational course, it provides the theoretical, historical and empirical basis to critically examine the making and operation of the modern/colonial/capitalist world-system economy and ecology and charts the histories of alternative social economies and social ecologies, from past to present. On the one hand, the genealogy of dominant ideas, theories, texts and institutions, including (neo)classical political economy, modernization, ecological modernization, neoliberalism, green neoliberalism, and developmentalism (including sustainable development), are critically examined in how they enable epistemological, governance and management systems that produce ecological rifts in Earth processes, ecosystems, biotic and human communities. On the other hand, the course foregrounds the subjugated histories of ideas and movements that, in defending territories and communities, have sought to advance emancipation for humans and nonhumans and repair ecological rifts upon principles of care, equity, justice, and sovereignty and self-determination that regenerate ecosystems while restoring dignity, equity, and resilience.
