PAPER 1: GLOBAL GEOGRAPHICAL ISSUES – CHALLENGES OF AN URBANISING WORLD Cities grow for two main reasons: rural to urban migration, and natural increase. Rural areas in developing countries have few jobs, apart from subsistence farming – and people often live in poverty. In the cities there are more jobs, better education and better health facilities and people are generally better off. These factors help to pull people to the city – this is called rural to urban migration. People why migrate to cities tend to be young (in their 20s and 30s) and they often start families once they are settled. So, the birth rate rises, causing the natural increase to rise also. This is sometimes called internal growth, which helps drive up the population of the world’s cities. Mumbai (India) Los Angeles (USA) A megacity is a city with more than 10 million people. Population: 20 million. Growth at 2.9% a Population: 12.9 million. Growth at 1.1% a year.

PAPER 1: GLOBAL GEOGRAPHICAL ISSUES – CHALLENGES OF AN URBANISING WORLD The quality of life for people in favelas is low, and poor housing contributes Rapid urbanisation and industrialisation in developing countries has created big to that. A lot of the homes are fairly solid – made from brick, wood and steel, environmental problems such as water pollution because many factories use and many have electricity. There are some well-established communities that rivers as a dump for industrial waste. have self-help clinics, food halls and meeting places. Air pollution can also be a problem. Exhaust gases from vehicles and smoke Elsewhere, more-temporary slum housing is built from anything that is from burning rubbish and factory chimneys pollute the air. As the Indian available – wood, cardboard, plastic sheeting etc. The slums: economy grows, more electricity is needed, which is generated from burning • Are usually overcrowded fossil fuels. • Lack proper sanitation • Experience pollution and disease • Are often built on marginal land. Rag-picking (making money from other people’s rubbish) is an important part of the informal economy. Up to 60% of the workers work in the informal economy. Other jobs might include selling food from roadside stalls, cleaning car windscreens and so-on.

Areas in cities that are built illegally, built by people who cannot afford proper housing. These people are usually rural to urban migrants. They build them with materials they can find, on land that doesn’t belong to them, They often have informal sector economy – cash in hand , no taxes, jobs created by the people themselves. They are built badly and are over-crowded &lack basic services like electricity. Life here is hard – no running water, no space, sewage, no police &some slums can be very dangerous and run by gangs. Often there is nowhere else for poor migrants to go. During monsoons season heavy rains make houses unstable. Due to no sewage and sanitation, water contamination is common and people get ill with diseases like cholera, diphtheria and hepatitis. In Dharavi, the settlement which is home to 1 million people per square mile. Good things - They do have a strong community spirit and barely any crime. Also almost everyone is employed in the informal sector. The city authorities of Mumbai want to improve the quality of life of the people who live there. Current approaches across Mumbai are for whole DEMOLITION of the slums which are replaced by high rise tower blocks with 14 stories for people to live in. The land upon which Dharavi is built is next to Mumbai’s financial district. This makes it a prime target for redevelopment. These types of redevelopment are planned for Dharavi by the Slum Rehabilitation Authority (SRA). They have proposed a $2billion development project.
