Neelkes most recent MVI-grant is on so-called crowd-based innovations. These are initiatives in which citizens collectively initiate activities, provide services, or arrange funding (e.g., local wind farms, community gardens, off-the-grid water treatment, repair cafes). These initiatives may provide opportunities for addressing societal challenges, but they may also pose significant challenges as they often occur in the context of traditional, well-established, institutional and governance structures and practices. The gap between these traditional structures and radically new initiatives prompts questions about how public values (quality, legitimacy, efficiency, equity) can be safeguarded.
