A Continental/Subcontinental Region (Leaving Cert Geography): Revision Notes
Human Processes
Race and race relations in Brazil
Brazil represents one of the world's most diverse multicultural societies, shaped significantly by its complex colonial past. The country's demographic composition reflects centuries of interaction between different ethnic groups.
Historical background and demographic composition
Brazil's multicultural character stems from its colonial history, which began when Portuguese settlers arrived in the sixteenth century. The indigenous population, consisting of nomadic tribes, was the original inhabitants of the region. However, the colonial period dramatically altered the demographic landscape through the forced importation of enslaved people from West Africa to work on sugar plantations. This system of slavery persisted until 1888, making Brazil one of the last countries to abolish this practice.
Afro-Brazilians: People of African descent living in Brazil, representing the largest population of African origin outside the African continent.
Geographic distribution of ethnic groups
The distribution of different ethnic groups across Brazil shows clear regional patterns that reflect historical settlement and migration patterns:
- North-eastern regions (particularly around Salvador): Highest concentration of Afro-Brazilian populations
- Southern and south-eastern regions: Greatest concentration of people with Portuguese and other European heritage
- Many Brazilians have mixed ancestry but are typically classified as either white or Afro-Brazilian based on physical appearance
This geographic distribution directly reflects Brazil's colonial history, with the northeast being the primary entry point for enslaved Africans, while European immigrants later settled predominantly in the south and southeast.
Racial inequality and social challenges
Despite Afro-Brazilians representing a significant portion of the population, substantial inequalities persist across multiple dimensions of social and economic life:
Economic disparities:
- White Brazilians earn on average 2.4 times more than Afro-Brazilians nationally
- In Salvador (a former slave port), this gap widens to 3.2 times more
- Afro-Brazilians are significantly more likely to experience poverty
Urban housing inequality:
- In Rio de Janeiro's favelas, over half the residents are Afro-Brazilian
- In wealthy neighbourhoods, only 7% of residents are Afro-Brazilian
- This demonstrates the stark contrast in living standards between racial groups
Government responses: The Brazilian government has implemented affirmative action policies, including reserving half of university places for the poorest students from public schools to address educational inequalities.
Favela: A settlement consisting of makeshift shelters constructed from scrap materials, also known as shanty towns or slums.
Native Brazilians
Population decline and historical impact
The indigenous population of Brazil has experienced dramatic decline since European contact. Historical estimates suggest that 500 years ago, between 2-6 million native people inhabited the region. Today, only approximately 350,000 indigenous people remain.
This represents one of the most severe population declines in human history, with the indigenous population dropping by over 90% since European colonisation began.
Causes of population decline
The devastating reduction in indigenous population resulted from several interconnected factors that created a perfect storm of demographic collapse:
- Forced labour and land confiscation: Many indigenous people were enslaved and had their traditional territories taken
- Disease introduction: European colonists brought illnesses such as influenza and smallpox
- Lack of immunity: Indigenous immune systems had no previous exposure to European diseases, making these illnesses particularly deadly
- Starvation and exhaustion: Displacement from traditional lands led to food insecurity and physical hardship
Current situation and government protection
Environmental threats: Today, deforestation poses the primary threat to indigenous communities as the Amazon Rainforest is cleared for agricultural development.
Government protection measures:
- The Brazilian government has designated 20% of the Amazon region specifically for indigenous tribes
- Current indigenous population is organised into approximately 200 distinct cultural groups
- These groups speak roughly 120 different languages, highlighting the cultural diversity within indigenous communities
Despite government protection, indigenous lands continue to face pressure from illegal logging, mining, and agricultural expansion, requiring constant vigilance to maintain these protections.
Population dynamics
Overall growth patterns
Brazil contains more than half of South America's total population, making it the continent's demographic centre. The country has experienced significant population growth, expanding from 17 million in 1900 to approximately 203 million by 2014.
Factors driving population growth
Several interconnected factors contributed to this rapid population increase, reflecting Brazil's transformation from a colonial to a modern society:
- Rural-urban migration: Movement of people from countryside to cities
- Improved living standards: Better healthcare, nutrition, and living conditions
- Higher birth rates: Initially driven by improved survival rates
Demographic transition
Brazil's population growth has followed the typical pattern of demographic transition, showing how development affects population dynamics:
Demographic Transition in Brazil:
- 1900: Country was in Stage 2 of the Demographic Transition Model (high birth rates, declining death rates)
- 2005: Progressed to Stage 4 (low birth and death rates)
- Recent decades: Population growth has significantly slowed
Density and distribution
Population density patterns
Brazil's population distribution is highly uneven, with an overall density of approximately 22 people per km². The most striking pattern is the concentration along the eastern coastline, where over 80% of the population lives within 320 km of the coast.
Historical settlement patterns
This coastal concentration reflects historical settlement decisions made during the colonial period:
- Portuguese colonial strategy: Early settlements were established along the eastern coast due to its more tolerable climate compared to the interior
- Geographic advantages: Coastal areas offered better access to trade routes and more moderate temperatures
Government redistribution efforts
Brasília Development Project (1954-1956):
- The government constructed a new capital city 1,200 km inland
- This planned city aimed to redistribute population away from overcrowded coastal cities
- Brasília is now Brazil's fourth-largest city with 2.9 million inhabitants
- The project successfully attracted migrants to the interior
Regional population characteristics
South-eastern region (São Paulo-Belo Horizonte-Rio de Janeiro triangle):
- Most densely populated area due to high industrial concentration
- Attracts millions of economic migrants seeking better employment opportunities
- Migration from rural areas has created pressure on urban services
- Housing shortages have led to extensive favela development
North-eastern harsh climate:
- Generally does not attract settlement due to extreme conditions
- Exception: coastal ports where temperatures are more moderate
The uneven population distribution creates significant challenges for Brazil's development, with some regions suffering from overcrowding while others remain underpopulated despite having natural resources.
Fertility rates and life expectancy
Changing fertility patterns
Brazil has experienced a dramatic fertility decline, with rates falling from 6.2 children per woman in 1960 to 1.79 in 2015. This decline reflects broader social and economic changes affecting family planning decisions:
Factors reducing fertility:
- Rising living standards and education levels
- Improved status and opportunities for women in society
- Career development taking precedence over early childbearing
- Delayed childbearing decisions
- Lower infant mortality rates reducing the need for larger families
Brazil's fertility decline has been faster than many developed countries experienced, reflecting rapid social and economic changes in recent decades.
Life expectancy trends
Current life expectancy figures reflect Brazil's status as a middle-income developing country:
- Males: 68 years
- Females: 76 years
- Comparison: Male life expectancy remains significantly lower than in Western European countries
Case study: Growth of an urban area - São Paulo
Overview and significance
São Paulo represents Brazil's largest and most economically important city, with Greater São Paulo housing 22 million people. Despite being located on the Tropic of Capricorn, the city enjoys a cooler climate due to its elevation of 760 metres above sea level.
Historical development
Early colonial period (1554):
- Founded by Jesuit missionaries during Portuguese colonial settlement
- Initially developed as a centre for exporting raw materials
18th century transformation:
- Gold discovery in São Paulo state dramatically increased the city's economic importance
- Population growth accelerated as the gold trade attracted fortune seekers
- The city became a central marketplace for sugar sales and exports
Educational and Financial Development (1934):
- Establishment of university status created a more skilled workforce
- Development as a financial centre attracted wealthy plantation owners to relocate
- Railway construction connected the city to Santos port, facilitating exports
- Road networks linked the city to inland coffee plantations
Industrial development
World War II catalyst: Industrial growth remained limited until wartime conditions created new opportunities. Brazil's inability to import needed goods during the war led to government investment in domestic production.
Manufacturing centre emergence: São Paulo's advantages included developed transport networks, large population, and raw material availability. Today, over 50% of Brazil's industrial production occurs in São Paulo, with major industries including petrochemicals, agricultural chemicals, fertilisers, and iron production.
Environmental and transportation challenges
Air pollution problems: Industrial development has created significant environmental costs that affect millions of residents:
São Paulo earned the nickname 'Cough City' due to poor air quality caused by:
- Approximately 7 million cars operating within the city
- Over 2,000 industrial plants contributing to pollution levels
- Rising respiratory disease rates correlating with pollution increases
Government response:
- Implementation of policies restricting vehicle emissions
- Introduction of driving restrictions to reduce traffic
- Reduction in industrial pollution through environmental regulations
- These measures achieved a 21% reduction in air pollution over four years
Migration and urban growth
Historical migration patterns: Following slavery's abolition in 1888, large numbers of former enslaved people migrated to São Paulo state seeking employment opportunities on sugar and coffee plantations. Their descendants continue to live in the city today.
Contemporary inward migration: As industry developed, São Paulo attracted large numbers of migrants from rural areas seeking employment opportunities. This rapid population growth placed enormous pressure on urban services, particularly housing provision.
Urban housing challenges
Favela development: Housing shortages led to extensive informal settlement development that now houses millions:
São Paulo's Housing Crisis:
- Approximately 8 million people live in favelas in São Paulo
- An additional 1.6 million live in favelas in Rio de Janeiro
- About 20% of São Paulo's population resides in favela communities
Favela characteristics and problems:
- Lack essential services including sanitation, clean water, and healthcare
- Experience high crime rates
- Narrow streets prevent rubbish collection, creating fire hazards and disease risks
- Constantly expanding as housing remains affordable and close to employment
Innovative solutions:
- Authorities have developed methods to burn methane gas from landfill sites
- This methane is used to provide electricity to favela homes
- This approach addresses both waste management and energy provision challenges
São Paulo's growth demonstrates both the opportunities and challenges of rapid urbanisation in developing countries, showing how economic development can create prosperity while also generating significant social and environmental problems.
Key Points to Remember:
-
Brazil's multicultural society reflects its colonial history, with significant inequalities persisting between racial groups, particularly affecting Afro-Brazilians who earn significantly less than white Brazilians
-
The indigenous population has declined dramatically from millions to 350,000 people, with government protection measures now reserving 20% of the Amazon for native tribes
-
Brazil's population growth followed the demographic transition model, progressing from Stage 2 in 1900 to Stage 4 by 2005, with fertility rates dropping from 6.2 to 1.79 children per woman
-
Population distribution is highly uneven, with 80% living within 320km of the east coast, leading to the development of planned cities like Brasília to redistribute population
-
São Paulo exemplifies rapid urban growth challenges, housing 22 million people with significant industrial development but facing serious problems including air pollution and extensive favela development affecting 8 million residents
