to the worldwide challenge of change in human 

 settlements. 



A Global Community-Building Initiative . We 

 recommend that the United states offer to contribute to 

 an expanded international program, involving a central 

 role for the new U.N. Habitat Center in Nairobi, that 

 would support global community-building efforts aimed 

 at providing minimum shelter and services for all 

 people of the world. 



Such a U.N. -sponsored program might begin by 

 providing capital assistance for efforts to organize 

 metropolitan growth and redevelop urban slums and 

 blighted areas. Examples of the kinds of programs that 

 might merit support are in Bogota, Colombia, and 

 Karachi, Pakistan. 



For relatively affluent countries, a total city- 

 building effort may be feasible. Bogota has planned 

 three massive satellite cities around its periphery to 

 help accommodate the expected rise of population from 3 

 million to 9 million by 1990. This expansion will help 

 meet the need for shelter, jobs, water, and other 

 services in the existing central city and prevent the 

 unplanned spread of urbanization that would destroy 

 nearby sources of food (American City Corporation 

 1974) . 



The construction of the satellites is to be 

 accompanied by two major new city-in-city projects 

 within Bogota, predominantly for low-income residents. 

 One of these is near the center of the old city, in an 

 area of plentiful jobs that lacks satisfactory nearby 

 housing and services and requires substantial upgrading 

 of the neighborhood. By the end of the century, this 

 new city of Sans Facon is expected to house 3 00,000 

 people (American City Corporation 1976a) . The other 

 city-in-city will introduce job opportunities and 

 services in an area devoted mainly to housing. Ciudad 

 Kennedy and other areas devoted exclusively to housing 

 have imposed substantial commuter problems on their 

 residents, who must travel long distances to find work. 



Techo, the new city, has been designed to correct 

 these conditions. Total population of the area will be 

 increased from 150,000 to 500,000, jobs will be 

 expanded in retail services and office employment, and 

 a development corporation established to carry out the 

 work will capture increasing land values to help 

 finance the project (American City Corporation 1976b) . 



Another type of community-building effort for the 

 very poor is demonstrated by sites and services 

 projects. The "metroville" program in Karachi, 

 proposed by a U.N. -sponsored study, calls for a series 

 of compact communities of 40,000 to 50,000 people vvho 

 would build their own housing on sites equipped with 

 water, sewer, streets, schools, clinics, markets, and
