Where are the People
Resources, Terrain and Population Densities
Case Study 1: Some Population Variations within Italy
North Italian Plain
Is densely populated
Factors that Affect Population Distribution
Land
Consists of an almost flat plain
Is covered largely in rich alluvial soil, which has been deposited by the River Po
Agriculture
Flat land, rich soil, plentiful rainfall and summer heat give rise to prosperous agriculture.
Intensive farms provide a high yield per hectare
Transport
Flat land has favoured the building of roads, railway lines and canals
This region has a dense transport network which assists trade and encourages settlement
Manufacturing
Is the industrial heart of Italy
Southern Italy
Is less densely populated than the North
Factors that Affect Population Distribution
Land
The Apennine Mountains dominate much of the south of Italy and some 80% of the region is mountains
Soil cover is thin
Agriculture
Mountainous land, poor soil and long, dry summers have created difficulties for agriculture
Many farms are small and unproductive
Transport
Mountainous land has made the building of roads and railway lines difficult and expensive
This has had discouraged communications, trade and settlement in southern Italy
Manufacturing
A shortage of capital, communications and industrial tradition discouraged manufacturing in southern Italy
Case Study 2: The Dublin Region
Has a rapidly growing population and now contains one-third of all people in the Republic of Ireland
The Dublin Mountains - very low density
Are short distance from Dublin's southern suburbs
They have been preserved as an amenity zone, so urban development on them is not allowed
Are lightly populated
West County Dublin - high density and growing rapidly
Has experienced very rapid population growth
Contains many rapidly growing outer suburbs such as Bluebell and Greenhills
Big satellite towns such as Tallaght, Lucan and Clondalkin have grown rapidly outside the western suburbs of the city
Some stellate towns serve as dormitory or commuter towns to Dublin
North County Dublin - moderate density
The expansion of city suburbs into North County Dublin has been hindered by the presence of Dublin Airport and Fingal County Council wishes to maintain market gardening on the fertile land of this area
Near the coast, however, population densities are much higher. Satellite towns such as Swords have grown rapidly and are connected to Dublin by rail and by roads
Dublin City and Older Suburbs - high density
Dublin City is densely populated because there are many jobs and services available
Dublin is Ireland's leading commercial and industrial city
It is Ireland's chief port and is the meeting place of many principal roads and railway lines
It is our capital city - the city where our government meets
It is Ireland's biggest education centre, with large universities such ass University Collage Dublin and Trinity Collage
Because of many jobs and services that it offers, many people migrate to Dublin from other parts of Ireland
How Social and Historical Factors Affect Population Densities
Case Study 1: The West of Ireland
Population densities in the west of Ireland has varied over time
In the early Nineteenth century the population grew rapidly. Famers divided their farms between their sons, so that many people had access to small plots of land. They grew potatoes, which produced a large amount of food per acre
Between 1845 and 1849, a disease called blight destroyed the potato crop. The Great Famine occurred. More than one in four people died or emigrated. The population fell dramatically
After the famine, farmers began leaving their famers to their oldest sons only. Fewer people now had access to land. Those who had usually emigrated. The population continued to fall steadily
By the 1960s the economy imporoved and people had more wealth. Emigration slowed down and the population began to stabilise
In the late 1990s Ireland's 'Celtic Tiger' economy resulted in more jobs and much more wealth. The population of the West began to increase
Population densities in the West of Ireland
Population is declining in some rural areas
Why population is declining
The terrain (landscape) is hilly, rocky and boggy. Soils are often is thin and infertile and farming difficult and unprofitable
There are few local industries or services to give employment. Entertainment facilities are often limited
It is often difficult for people to get planning permission to build new homes n picturesque rural areas
Case Study 2: Some population variations in Brazil
Why most Brazilians live near the coast for historical reasons
In the sixteenth century, the Portuguese began to colonise Brazil. They arrived on the East Coast and set up trading towns along
Some trading towns eventually grew into huge industrial cities, such as Rio de Janeiro and Sao paulo
The Portuguese's set up big estates called plantations near the coast. They imported millions of kidnapped Africans to work as slaves on the planation
Why the Amazon Basin is sparsely populated
The Amazon Basin is home to local 'Amerindian' peoples, but it has been heavily settled by European colonists
Europeans were not comfortable with the hot, wet equatorial climate of the region or with its dense rainforest
Only 75 of Brazils population live in the Amazon Basin
