The Sustainable Development Goals will need to be localized and aligned with local development plans and city development strategies (CDS). The CDS is a shared vision of the city and action plan of the city developed through a participatory process. The project addresses the accountability deficit in cities in Latin America by focusing on six cities. Accountability here is defined as accountability of city governments towards city residents, as well as accountability towards regional, local, and international targets and agreements. Accountability will be crucial for monitoring the progress on the Sustainable Development Goals and for meeting the Goals. The project creates physical and virtual spaces of collaboration between key city stakeholders, which include politicians, officials, civil society, academia and the private sector. Emphasis is given to local demand and ownership of accountability initiatives and monitoring systems. City officials will be invited to the Urban Accountability Academy, a workshop on accountability and sustainability issues. Local training institutions will participate in a training the trainers workshop and will support the Urban Accountability Academy. City stakeholders can propose and discuss city accountability initiatives and monitoring systems using the Online Urban Accountability Academy platform. This Online Urban Accountability Academy will also be a depository of knowledge and best practices. Each city will organize a City Accountability Lab where stakeholders come together to discuss and decide on proposals. The project will culminate in follow-up visits to three cities. The expected outcomes of the project are enhanced capacity of city stakeholders, closer collaboration between city stakeholders, and initiation of city accountability initiatives and monitoring systems.
