Using examples, explain the challenges of rapid mega city growth

Extracts from this document...


´╗┐Using examples explain the challenges of rapid megacity growth A megacity is an urban area with a population of over 8 million; examples include Sao Paulo, Mumbai, Los Angeles and Beijing. As the global population rises and rural to urban migration increases, there is a rapidly growing number of megacities in the world. Although megacities boast many benefits they also have negative externalities such as poor living conditions (growth of slum areas), increases rate of crime, stress on services, traffic congestion, urban sprawl and environmental problems such as pollution and it can be difficult to manage the growth of megacities in a sustainable way Mumbai is one such megacity which is facing problems as a consequence of rapid growth. Within Mumbai the slum area of Dharavi houses 600,000 people in one square mile of land, which illustrates the crowded conditions of such slum areas. ...read more.


Government along with charity and aid workers face the challenge of policing these areas and giving the dwellers a chance at earning money so they can move to legal housing. There is also an issue of crime. Crime is very high in Dharavi and there are no police patrols in the slums. Barely 10% of the commercial activity in the slum is legal but the average household wage in Dharavi is well above that in rural areas of India. Some parts of Dharavi have bars, beauty parlours, clothes boutiques and even cash machines. If the prospects of the dwellers and the future generations of the slums are to escape poverty, a challenge the government faces is educating the children that live in the slums to give them a better chance of getting a good job. The government along with charities and non-governmental organisations (NGO?s) ...read more.


Also, in many megacities there is a growing number of middle class families who can afford cars and in India, Tata motors have created the world?s cheapest new car at just $2000 which further encourages car ownership. The governments of megacities face the challenge of reducing traffic congestion on roads to reduce carbon dioxide emissions and prevent the economy from suffering. Another challenge of rapid megacity growth is urban sprawling. Urban sprawling is the unplanned, uncontrolled spreading of urban development into areas adjoining the edge of a city. This is a problem because it can lead to the loss of valuable, largely undeveloped, wild or agricultural land surrounding urban areas. These areas are important to sustain wildlife populations and keep the planet in balance. Overall there are many challenges that arise from rapid megacity growth such as housing shortages leading to the development of slum areas, strains on services, increases crime and growing amounts of pollution and the governments of megacities must find a way to minimise these negative externalities. ...read more.

  1. Road Traffic Accidents

    When roads curve, the outside edge of the curve is often raised such that the road is at an angle. This banking of the roadway takes the speed of traffic into consideration, and makes it easier for vehicles to manage the curve, and makes it less likely that a vehicle will go off the roadway at a curve.
