This volume provides visionary approaches within the multi-disciplines engaged with informal settlements covering three main themes; ¿Innovative Policies and Strategies to Informal Urbanism¿; ¿Production, Operation and the Life-World of Urban Space¿ and finally ¿The Dynamics of Informal Settlements¿. The book reflects multi-disciplinary experiences dealing with informality, where authors from a number of global regions present cases, practices and ideologies related to their respective context. This is elaborated through fifteen selected papers, most of which, were presented at the International conference: ARCHCAIRO 6 (the 6th International Conference), "RESPONSIVE URBANISM IN INFORMAL AREAS TOWARDS A REGIONAL AGENDA FOR HABITAT III". The conference was organized as a collaborative activity within the ¿Informal Urbanism Hub¿ of the HABITAT University Network Initiative
