Problems of urbanisation Essay Example

the right to emit more from less emitting ones, which should supposedly ensure a controlled level of pollution emission (Afify, pp.8).

On an optimistic view, single policies like the tradable permits can to some extent put one specific problem among the numerous ones of urbanisation under control. Besides, leading actions initiated by one region, in this case the US, enables others to learn from the first case study, and may encourage others to follow suit, which would expand the scale of the outcomes. In addition, they may also contribute to better designed policies in the future, as they provide decision makers valuable data.

From a more critical perspective, there exist factors that limit the degree of success of a SD policy in tackling problems of urbanisation. Firstly, regarding any single policy alone, it is always a present challenge to measure the outcomes, and hence evaluate the extent to which it solves the targeted issue. Take the tradable permits again, it is extremely difficult, if not impossible, to judge if the policy has directly contributed to any identifiable improvement in the quality of air, since air flows across borders and is affected by uncountable factors.

Secondly, because of the much higher degree of interlinkages between the three pillars, economics, social and environmental, within urbanised areas, a single policy will unlikely achieve desired outcomes without the systemic introduction of a series of policies designed to compliment each other by addressing each pillar. Thirdly, because of this requirement of systemic changes in policies, it necessitates a long-term view regarding the time frame required to design and establish the policies, which in many cases conflict with

short-term policy interests.

In conclusion, the problems of (rapid) urbanisation are real and inevitable. Sustainable development is a policy approach that is increasingly adopted and recognised. However introducing policies under the label 'sustainable development' does not necessarily imply serious effort is being committed and effective outcomes are being produced, due to the problems outlined above. It is worth noting that due to limited capacity, this short essay has barely scratched the surface of the topic, and there is much depth to be explored for a better understanding.
