The New Urban Agenda (NUA) formed a new basis from which urban policy might be developed. Focusing on the accessibility of all components of a city, for all of its citizens, was a key step towards further improving approaches to development and solving urban issues. Where previous urban development approaches focused on a physical lack of urban infrastructure, the NUA centered on the lack of accessibility in many aspects of urban life for disadvantaged citizens. As development actors begin to realize more and more that accessibility is a key factor in creating successful development schemes, more documents like the New Urban Agenda can be expected to place accessibility for minorities, women, persons with disabilities, and children in a place of priority.
People have difficulties accessing the city in mainly two ways. One is although a person lives in the city, he or she cannot fully access resources and spaces in the city. The other way is that a person does not live in the city and cannot travel to the city for its concentrated resources. Therefore, sustainable inclusive urbanization is not just about improving accessibility within the city, but also about improving connectivity between the city and other areas.
