TEc debate motion "This house believes that restricting the growth of cities will improve quality of life." - Not automatically but a check would certainly help a great deal...
I have to vote for the motion for every right reason I can think of.
I do acknowledge though that after a check to a city's growth is achieved it does not follow suit quality of life improves effortlessly.
Indeed a well managed city is one that reaches a level of stabilisation regarding most major and minor sub-systems an Urban System is made of.
Population which of itself drives infrastructural needs in the broadest sense is a variable of key importance throughout.Why else would cities grow, sprawl or bloat if not as a consequence of rising populations?
Sub-systems are geared to satisfy the requirements of a city's inhabitants.Once supply meets demand the quality of life of individual citizens may be expected to rise.
Over the last decades most city growth has taken place in the developing world.
Large cities have mushroomed to become gigantic continuous agglomerations. These call into question the very concept of city as an organized urban area.
Cities already bursting at the seams, barely able to cope with established residents have faced an influx of new settlers flocking in at ever faster rates.
Years ago Bombay added a thousand new migrants a day to its population.The latest figures I hear have nearly tripled raising the total to 1 million a year.
Utilities, transport, housing severely strained or simply collapsing under the sheer weight of demand for which supply is not there.Nor can it be created in a planned way to keep up with surging needs. Not on this scale.
Even in a rich developed country with an advanced ready-for-expansion- working-infrastructure in place an adequate timely response would be unattainable.
How then to manage the whole process?There are no easy answers to such overwhelming problems presented on a scale that defy any realistic proposition.Cities have lured millions to them since long, their pulling power directly linked to perceived higher chances of success for the individual.
Some might argue that new migrants set up new businesses, trades, jobs and wealth is created. New economic activity is developed.
While this is true up to a point a balance must still be struck that does not put so much pressure more problems arise than opportunities are created.
Those who have briefly overflown large slum areas or unplanned neighbourhoods of many a city around the world cannot fail to grasp the sheer size of problems. And the challenges posed to overcome them.The pervasiveness of atrocious sanitary conditions, the blight, disease, social misery or the grinding poverty affecting hundreds of thousands or millions help put ideas on sound footing.
A clearer perspective emerges that may prove crucial to public policy decison-makers in their quest to address a city's problems.
Last but not least is the case to have a population as evenly spread as possible across a country's territory.This entails the existence of several-tier urban areas dotting the geography of the land as well as rural populations to keep the countryside going, alive and productive.
