This paper describes Mexico City's environmental problems, how and why they
arose. and how they have changed over the last ten years. This includes an
interest in how the problems have been affected by environmental policies
and demographic structures. It highlights how some environmental problems a
re simply characteristics of large cities while others can only be understo
od in relation to specific economic, political and geographic factors. It d
iscusses what constrains the cheapest and most effective solutions - for in
stance the lack of an integrated public transport policy and measures to pr
omote energy and water conservation The constraints include complex and oft
en deep-rooted political and administrative factors - for instance the lack
of funding available to the municipalities which house a large and growing
proportion of the Low income population and the powerful vested interests
which benefit from the lack of an integrated transport policy. The paper al
so shows up the inaccuracies in much of the general literature when referri
ng to Mexico City - for instance the exaggerations as to its population and
size and the assumption that much reduced population growth rates would ne
cessarily bring improved environmental conditions.
