Given the rapid growth of cities in the developing world, and their po
litical importance - particularly during this period of structural adj
ustment - it is surprising that the writings of urban researchers have
not had more impact on the policies of development agencies. To under
stand the dynamics of research in Africa, Asia and Latin America, this
article summarizes major findings in a large comparative project invo
lving researchers in some fifty countries. Their production and the li
mitations on their work are discussed in terms of levels of production
, major disciplines, the dispersion of research activity, and the new
modalities (such as NGOs and international agencies) which are increas
ingly involved in urban research. The article concludes that urban res
earchers are becoming increasingly more central to local policy-making
as the policy community broadens and their work responds more effecti
vely to local needs.
