Narratives like those portraying development workers as heroes and local populations as victims needing to be saved from their own unsustainable practices have led to problematic policies and interventions. Based on fieldwork across four continents, this Element critically analyzes such metanarratives. First, it demonstrates the ways their simplifying, universalistic narrative plots fail to capture more complex lived realities. Second, it argues that such metanarratives on development are converging with influential metanarratives on climate change and sustainability, thereby strengthening hierarchical geopolitical mindsets. Third, it uncovers how the emergence of for-profit sustainability superhero metanarratives reinforces universalistic development logics by combining these logics with global business management logics. The Element concludes that a multiplicity of locally grounded stories and related forms of agency must be mobilized and recognized so that policy and practice are premised upon lived realities, not abstract and unrealistic global imaginaries.
