ABSTRACT
Introduction Since the publication o f the original Models in geography (Chorley & Haggett 1967) some 20 years ago, hum an geography has changed dramatically. It has m atured theoretically, it is more directly oriented to social problems, and it has achieved an awareness o f politics w ithout sacrificing its advance as a ‘science’. This transform ation can be traced to the emergence, and the widespread acceptance, o f a new set o f models which have a com m on root in the notion that society is best understood as a political economy.
