After the 1960s, rapid urbanization in developing regions in Latin America, Africa, and Asia was marked by the expansion of low-income "irregular" settlements that developed informally and which, by the 2000s, often constituted between 20-60 percent of the built-up area of metropolitan areas and other large cities. There has been a variety of research directed at the housing policies involved with these informal settlements, yet apart from the activities of Latin American Housing Network (LAHN), there has been minimal attention directed at the earliest portion of settlements that formed some 25-40 years ago that now form a large part of the intermediate ring of the cities. This volume breaks new ground by opening up a new generation of housing policy in Latin America cities with broader application for other developing countries. Its editors bring unique perspectives: Peter Ward coordinates the LAHN, and Edith Jiménez and María Di Virgilio are founding members of the network who have led project teams in Guadalajara and Buenos Aires respectively. Developed as a coordinated collaborative research project, the volume encompasses nine Latin American countries and eleven cities. The editors and contributors offer original perspectives on the policy challenges facing much of the low income housing of Latin American cities; document the changing nature of the "first suburbs"; present comparative survey findings in order to better understand the types of consolidated settlements that exist today; describe the physical nature of the dwellings themselves; identify the reasons behind market dysfunction that impede the operation of consolidated housing informal markets in Latin American cities; and outline a new generation of housing policies that will support the processes of densification, rehabilitation, and regeneration of these settlements. This book is the first and only composite overview of the research findings and advocacy of the generic policy lines that the LAHN identifies as central to a new generation of housing strategies and approaches. Researchers and practitioners working on housing theory, housing policy, comparative spatial and sociological research, and urban development issues will find the book highly significant.
