Challenges in Managing Urbanization        


Urbanization Home            Key Facts         Make A Difference      

Air Pollution
Cars, factories and burning waste emit dangerous gases that change the air quality in our cities and create health problems. Dangerous gases like carbon dioxide and nitrogen oxides cause respiratory or breathing diseases (e.g. bronchitis and asthma) and have negative effects on the environment.

Water Pollution
With the increased population, it becomes difficult to manage the waste generated in cities. Most of the waste is discharged or dumped into rivers or onto the streets. The waste pollutes water and makes it unfit for human consumption. Subsequently, it becomes more and more difficult for people in cities to get clean water. Some cities in Africa are unable to provide adequate water supply because most of the water is lost in pipe leakages. In fact, most people in cities in developing countries are forced to boil their water or to buy bottled water, which is very expensive.

Other problems created by urbanization:

Development of slums.

Destruction of forests and other nature reserves around cities for settlements and agriculture.

Increased poverty.

Increased crime.
