This is the third of three volumes published as a part of the American Institute of Planners' two-year consultation on "the next fifty years." Leaders in the fields of education, government, medicine, planning, civil rights, transportation, and conservation discuss their expectations for urban planning in regard to the urban crisis and specify steps to be taken by 1970, 1980, 2000, and 2017 to achieve man's optimum environment and coordination of forces that produce the modern city. They attempt to delineate the essential plans to be made in order to implement programs conceived, to personally involve the greatest number of people, and to specify the leadership required. Each contributor discusses the implications of his recommendations at the world, national, regional, and local levels, as well as the professional expertise that will be needed to carry them out. Although emphasis is placed on setps to be taken in urban areas, recommendations are also presented for rural areas, small towns, wilderness, and open beach areas. Topics covered include minority groups; improved education; health and leisure; the contributions of urban form, transportation, and housing to a new standard of life; a national policy for development; and new institutions to serve the individual.
