title: The third world goes to town:  will U.S. policy catch up?
abstract: "Third World cities are growing so fast that in the 21st century over half the world's population will be urban.  This shift will need to be recognized by all aid donors, and particularly by the USA.  Sustainable development will be possible only if Third World governments--central and local--can be assisted to meet the challenge of this massive rural to urban transition."
