This has led to urbanisation and the rise of megacities. Megacities have over 10 million people in the urban area. ### Megacities ![Megacities](https://image-v2.cdn.app.senecalearning.com/2018-08/2d70139b-877b-451f-9c9e-9d5d3c395baf/beijing-.jpg) - In 1990, there were just 10 megacities across the globe. By 2030, it is expected to rise to 41 according to the UN. - Megacities such as Mumbai, India and Karachi, Pakistan are growing rapidly. - This is because of rural-urban migration whereby push factors force people to leave their rural homes. Pull factors are factors that encourage people to move to the urban areas. - Megacities have a higher birth rate than the death rate, so this natural increase causes the population to continue to grow. ### Push factors ![Push factors](https://image-v2.cdn.app.senecalearning.com/2018-07/eb17b0e6-fdf6-40d6-b301-484d57af62d8/education-learning.jpg) - Examples of push factors include: - A lack of access to education. - A lack of access to health care. - A lack of access to clean water and sanitation. ### Pull factors ![Pull factors](https://image-v2.cdn.app.senecalearning.com/2018-08/7aaa651f-f08b-47f0-a24f-595649daf19e/job-centre-.jpg) - Examples of pull factors include: - Better employment opportunities in the city. - Better healthcare available in the city. - An overall better quality of life. ### Problems with megacities ![Problems with megacities](https://image-v2.cdn.app.senecalearning.com/2018-07/26021834-ea92-4f3c-a9e7-33fdc37f4080/poverty-beggar.jpg) - Rapid population growth can cause environmental and social problems. - For example, there is a shortage of resources, a shortage of houses, a shortage of services. - A shortage of homes is caused by the numbers of people moving to the cities on a daily basis - infrastructure cannot be built fast enough to keep up with demand. - This leads to a lower quality of life, an increase in unplanned settlements and an increase in poverty. ## Megacities - Karachi, Pakistan Karachi is a megacity growing at an annual rate of 5%. It generates over 25% of the total GDP of Pakistan. Such rapid population growth is causing significant social and environmental problems. ### Unplanned settlements ![Unplanned settlements](https://image-v2.cdn.app.senecalearning.com/2018-08/05cb5c0c-84f0-40d5-bf6a-abb0bcb14c60/mumbai-slums-river.jpg) - The UN estimate that 50% of the population live in slums or unplanned settlements. - Orangi Town is Asia’s largest slum and found in Karachi. It is believed to be home to around 2.4 million people. ### Tax avoidance ![Tax avoidance](https://image-v2.cdn.app.senecalearning.com/courseImages/biology/4.2.1-%20Respiration/no-money-2070384_640-min.jpg) - With around 75% of the slum dwellers in Karachi working in the informal sector, the Government does not receive taxes from these people. - So the Government does not have the income to spend on improving education and healthcare which would improve the quality of life of the people of the city. ### Water shortages ![Water shortages](https://image-v2.cdn.app.senecalearning.com/courseImages/biology/2.4.1%20-%20Heart%20diseases/leaking-pipe%20-%20Edited-min.jpg) - According to the World Bank, Pakistan is one of the most water stressed countries in the world. - A lack of infrastructure to supply clean water makes this a serious problem for Karachi. - The WWF estimates that the city loses 30% of its water through leaks in the system. ## Megacities - Mumbai, India Mumbai is India’s largest urban area and was home to 22 million in 2015. It has doubled in size since 1970 and, as a result, suffers social and economic problems because of its rapid growth. ### Unplanned settlements ![Unplanned settlements](https://image-v2.cdn.app.senecalearning.com/2018-03/0303ff48-c0e3-4ecb-8b86-dce772d10a6c/shutterstock_228987337.jpg) - Dharavi is the largest slum area in Mumbai. - 5,000 people are employed in the slum in recycling plastics. - People find their own informal employment in these areas. In these slum areas, people have little or no access to basic services: water, sanitation, power and waste management. ### Air pollution ![Air pollution](https://image-v2.cdn.app.senecalearning.com/2018-03/47ae63cc-8fd9-4851-a84d-f1c8032a2a21/shutterstock_1014679609.jpg) - Air pollution in Mumbai is an example of an environmental problem caused by its rapid growth. - In 2018, Mumbai was ranked the 4th most polluted megacity in the world. ### Urbanisation ![Urbanisation](https://image-v2.cdn.app.senecalearning.com/2018-08/e27b68ac-31d7-4a88-8947-e008713298e5/coins-1726618_1920.jpg) - People move to megacities from the surrounding area to earn higher wages than they could in agricultural/rural areas. ## Test yourself on Megacities - Which of the following is NOT a problem associated with the growth of megacities? - How many megacities does the UN expect there to be by 2030? - At what rate is the megacity of Karachi growing? - What percentage of Karachi's population live in slums? - How many people are employed in recycling plastics in Dharavi?
