Developing countries are urbanizing at an incredibly fast pace and, in many cases, with unplanned settlements that pose enormous challenges. Growing cities need to define the urban planning frameworks that will guide the construction of new neighbourhoods and city extensions.
The Urban Planning and Design focus area of UN-Habitat aims to support cities, regional and national authorities in adopting improved policies, plans and designs for more compact, socially inclusive, better integrated and connected cities that foster sustainable urban development and are resilient to climate change. This lecture provides an introduction on why this is relevant and how it can be achieved.
Urban growth of the past 30 years has largely resulted in crowded slums and sprawling settlements in the urban fringe. Cities are consuming land, increasingly, to accommodate new developments. In some regions, urban land has grown much faster than the urban population, resulting in less dense and, in general, more inefficient land use patterns. In addition, this is often happening in the absence of a viable spatial structure.
