Abstract:
This study has taken a long time to appear: its roots go back to 1972, although
formally it was begun in 1973, having been crystallized one hot day on the road
to Mrewa. A rather simple comparative study of models in developing
countries seemed to be indicated at that time, but subsequent travel to various
countries gradually resulted in some changes of view. To experience of
Southern Africa and Mauritius was added brief experience of Ghana , Egypt,
Morocco and Australia, whilst longer stays in Bahrain and Hong Kong were
helpful: to these were added kind invitations to visit Costa Rica and Brazil,
whilst lengthy recent stays in Korea and Saudi Arabia have been influential.
These working travels, added to shorter visits elsewhere, have both prolonged
the study, and, hopefully, directed its aim more usefully.
Amongst the many very kind people and institutions I must thank for help,
hospitality and stimulus on the way are: the Central Office of Statistics at Rose
Hill, Mauritius; Denis Fair, John Lea, John Muller, Nie Patricios and Joan
Verster at the University of the Witwatersrand; the City Engineer of Salisbury,
Rhodesia; the Colegio Federado de Arquitectos y de Engenieros de Costa
Rica, and Esther Salas de Weiss in San José; the Universidade de Säo Paulo
and its Escola de Engenharia de Säo Carlos, and FAPESP for their support
through Professor Romeu Corsini, Professor Azevedo and EMPLASA in Säo
Paulo, and especially in Säo Carlos, Dante and Julieta Martinelli and José
Savério Lia and other friends in CPD ; and the Korea Research Institute for
Human Settlements and Dr. W. Y. Kwon in Seoul.
F or helpful assistance in securing reference material, the County Libraries
of Cheshire and Buckinghamshire, and through them the National Lending
Library, must be thanked once again. Acknowledgement is expressed also to
the various authors quoted herein and their publishers, and perhaps especially
those whose models are cited: though some criticism of their models is made,
no one should doubt the pioneering nature of much of this work.
Finally, as always, I must thank my wife for bearing with kindness and
affection the many long absences and absentmindednesses that a work like this
