It is inspiring to see investment going into the citizen engagement space, especially for urban sustainability. That Colab has managed to get so many local governments in Brazil to cooperate and make good use of their system is laudable. We have only recently launched our app, Urb, but hope to emulate the success of Colab in Africa. Urb is Africa’s first community participation platform for urban areas. Citizens set the agenda for change in their communities by sharing and reporting issues that affect them. This collective participation and action drives public service providers and policy makers to directly engage with citizens for a more inclusive approach to better service delivery. We are hopeful that there will be more investment in this space, especially in Africa.
