Transcript of Urbanisation

Urbanisation Urbanisation is the rapid growth of the population in urban areas. What is Urbanisation What causes Urbanisation? Urbanisation occurs because people move from rural areas (countryside) to urban areas (towns and cities). This usually occurs when a country is still developing. Impacts As cities grow, ecosystems are lost and urban areas are becoming increasingly unpleasant places to live in. The systems that sustain life adapt or are destroyed. People and their domestic animals compete with wildlife for space. Concrete is replacing forests and wetlands, smog is replacing clean air, traffic noise is replacing peace, and housing is replacing agricultural land. All of this is a result of urbanisation. Individual Management If you live in a city, you can ensure your home is in an area where residential density is highest. You can live in the same suburb where you work and your children go to school so that you may not need to own a car or use it every day. Using a car less means that less pollution is released into the atmosphere meaning that the natural environment is healthier and ecosystems are not lost! Goverment Management The government in some countries has introduced counter-urbanisation. This is the movement of people out of economically developed countries. Group Management Car sharing is when people can hire a car for a few hours or a whole day. Cars are parked nearby so they are convenient to access. Car sharing is a great way of reducing traffic congestion. Interesting Facts Levels of urbanisation in 1950 and 1990
1950 1990
World 30% 51%
More economically developed countries 53% 74%
Less economically developed countries 17% 34% Statement If everyone helps by reducing the use of their car, the impact of car pollution as a result of urbanisation can be reduced and the environment can be sustained. The End Alex McHarg
