In the face of threats of the seventh mass extinction and climate collapse, a planetary emergency has been declared by scientific and intergovernmental bodies. People across global civil society are coming together to respond. This module provides an interdisciplinary perspective on interacting dimensions of key socio-environmental challenges of the 21st century, and responses to them. Considering crises in land, food, water and biodiversity, we will critically analyse the intersections between systems of power and complex environmental processes, and the diverse ways in which people relate to nature and society. With an emphasis on ongoing responses to a multifaceted threat to life on earth, the module will enable you to understand interconnections between environmental and social crises, consider diverse activist and community responses, interpret sustainable development initiatives, and contribute to alternative visions of the future.
