Launched in 2010, it addresses issues of the local governance and urban risk. It entered its second phase 2012-2015; based on the success and stock taking by partners and participating cities in the first phase (2010-2011), the campaign will continue and shift its focus to implementation support, city-to-city learning and co-operation, local action planning and monitoring of progress in cities.
