Among these are the urgent need to halt uncontrolled urban sprawl, reverse the growth of urban slum populations, institute smart, safe and efficient urban transport systems, improve urban environments through creating safe public spaces, manage air pollution and municipal solid waste, as well as promote sustainable buildings, ecosystem corridors and consumption and production patterns.. All the targets and indicators of SDG 11 require sufficient planning and informed strategies, which are largely articulated in the need to have well-informed national urban policies. Many of these indicators build on the notable achievements registered during previous global agendas especially MDGs and the Habitat Agenda, including the notable fact that some targets now have reliable baselines to work with, many others are new and come as a response to the challenges and opportunities that urban areas face today in search of sustainable development outcomes. These periods are sufficiently long for the global community to have learnt a lot about the existing challenges of implementing the SDGs and how to deal with the teething problems in monitoring and reporting.
