From this more general, strategic perspective,innovation can bring four major types <strong>of</strong> benefits: (1)reviving and sustaining <strong>the</strong> social economy (e.g.. betterpolicies for human needs satisfaction); (2) changes insocial relations (e.g. new societal arrangements, new socialpact); (3) reinforcing existing, or creating new, institutionsfor improved urban management and governance (e.g.,regulation <strong>of</strong> land or social conflicts, new legislation);and (4) forward-looking changes to <strong>the</strong> urban space (e.g.resource redistribution, expanded access to services andpublic goods). Any value added by all <strong>the</strong>se social andinstitutional innovations will accrue primarily to societyas a whole, ra<strong>the</strong>r than private individuals or groups 26 ,enhancing <strong>the</strong> prospects <strong>of</strong> prosperity and giving its fullmeaning to <strong>the</strong> notion <strong>of</strong> ‘spatial justice’. 27Being a social construct, any city can be steered andshaped towards higher levels <strong>of</strong> prosperity. A fresh, differentvision <strong>of</strong> urban planning and design can combine with new,more insightful change narratives and development ideas.As urban risks and challenges keep changing over spaceand time, existing safeguards, instruments or mechanismsmust come under review and be adjusted as and whererequired. Innovation must also help reduce <strong>the</strong> cost <strong>of</strong>urban living. Innovative rules and legislation must support<strong>the</strong> transformation <strong>of</strong> <strong>the</strong> existing urban model. Thecurrent model is unsustainable for several reasons: endlessphysical expansion, intensive energy use, alarming anddangerous contributions to climate change, multiple forms<strong>of</strong> inequality and exclusion, and inability to provide decentjobs and livelihoods. 28 If ongoing urbanization is to usherin <strong>the</strong> city <strong>of</strong> <strong>the</strong> 21st century, <strong>the</strong>n this transformation mustbe grounded in a more effective and sustainable use <strong>of</strong>urban space. The city <strong>of</strong> <strong>the</strong> 21st century is a reinvented citythat is more productive, equitable and sustainable.

For all <strong>the</strong> paraphernalia <strong>of</strong>legislation, complex regulations and spatial design plans,a majority <strong>of</strong> those <strong>cities</strong> have continued with <strong>the</strong> flawedmodels which, as ‘advanced’ countries have finally foundout, are unsustainable in a variety <strong>of</strong> ways.Cities have found <strong>the</strong>mselves woefully unpreparedin <strong>the</strong> face <strong>of</strong> <strong>the</strong> spatial and demographic challengesassociated with urbanization, not to mention those <strong>of</strong>an environmental nature.
