This document provides an overview of the Crowd_USG project, which aims to investigate how crowdsourcing can advance participatory governance of urban sustainability. The project will analyze current applications of crowdsourcing for governance, study its use in Ghent through interviews, develop future scenarios, and outline a model for urban sustainability governance incorporating crowdsourcing. It will use methods like actor-network theory to manage the case study and engage the public. The project seeks to determine if and how crowdsourcing can fuel participatory knowledge production and policy-making for urban sustainability issues.
