What is the ontological significance of sustainability crises – and the struggles to overcome them? Drawing on Heideggerian perspectives – in dialogue with Laclau and Mouffe's discourse theories – I argue sustainability crises become meaningful at the level of everyday experience when they disrupt the flow of ordinary skilled practices and their orientations towards the future. Such disruptions trigger what Heidegger termed ‘anxiety’, which implies an erosion of life's coherence, meaning and purpose. Developing skills to ‘cope’ with sustainability crises may (...) enact alternative ontologies that restore what anxiety threatens; ‘skills for sustainability’ potentially disclose new worlds, meanings, values and goals. I illustrate this through vignettes of individuals transitioning to organic farming in India. I show how disruptions to farmers’ skilled practices triggered anxiety while also prompting the development of skills for alternative agricultural practice. These skills enabled new ways of experiencing worlds, non-human entities and the telos of everyday activity. (shrink)
