Urban Issues & Challenges Flashcards
Urbanisation
An increase in the number of people living in urban areas such as towns and cities
High rates of urbanization in LICs
Majority of population lives in rural areas;
Less economically developed —> as manufacturing industries set up in cities, more rural-urban migration —> attracted by jobs;
Rate of natural increase is high in younger cities;
Eg. Ethiopia
Decreasing rates of urbanization in NEEs
Urban growth varies;
Rapid economic growth;
Urbanization happened earlier, slowed down, but have not reached level of HICs;
Eg. Brazil, Russia, China, India, South Africa —> BRICS
Low rates of urbanization in HICs
Majority of population lives in urban areas;
Urbanization occurred during Industrial Revolution;
Rate of natural increase has decreased due to aging population
Megacities
Population over 10 million;
Natural Increase
When birth rate is higher than death rate: population increases
Natural Decrease
When death rate is higher than birth rate: population decrease
Push Factors (encourages people to leave an area)
- Farming is hard and poorly paid;
- Desertification and soil erosion make farming difficult;
- Drought and other climate hazards reduce crop yields;
- Farming is often at subsistence level, producing only enough food for the family, leaving nothing to sell;
- Poor harvests may lead to malnutrition or famine;
- There are few doctors and hospitals;
- Schools only provide a very basic education;
- Rural areas are isolated due to poor roads
Pull Factors (encourages people to move to an area)
- More well-paid jobs;
- Higher standard of living is possible;
- Friends and family live there;
- Better chance for better education;
- Public transport is better;
- Range of entertainment is available;
- Better medical facilities
Distribution of megacities
Over half world’s population lives in Asia —> large proportion of megacities in Asia
Slow-growing megacities
Located in S.E Asia, Europe, N. America;
70%+ population urban, no squatter settlements;
Eg. Tokyo, Los Angeles, Moscow
Growing megacities
Located in S. America, S.E Asia;
40-50% population urban, <20% in squatter settlements;
Eg. Beijing, Rio de Janeiro, Shanghai
Rapid-growing megacities
Located in S./S.E Asia, Africa;
<50% population urban, >20% in squatter settlements;
Eg. Jakarta, Mumbai, Manila
UK Population and Distribution
65.2 million;
82% live in cities;
Population density: 260 people/km^2;
West coast sparsely populated —> mountainous regions (eg, Pennines, Scottish Highlands, mountainous areas in Wales);
Where densely populated —> big cities (eg, London);
Fast-growing cities in South;
Slow-growing cities in North —> deindustrialization;
Densely populated cities in low-lying flat land, near coasts and rivers (historically: supported by farming, trade, industry)
Sustainable
idea that meets the needs of the people without making it more difficult for future generations to meet their needs
