A shift to the coast – Bournemouth (UK), Spain

and Australia

•What is coastalisation?• What has caused coastalisation to happen? And what problems can it create? •How has Bournemouth’s, Spain’s and Australia’s coastalisation developed?

Did you know? 3 billion people live within 100km of

the coast

Two thirds of our largest cities are within 60km of the sea

Coastal population densities are usually 80 people/km2 – 50% more than inland areas

These can rise up to 1000+ in the Nile and Ganges Deltas

Coastalisation

• Coastalisation is the ‘movement of people to coastal areas’ .

• These people require more homes and jobs.• In attractive areas this can lead to conflict as

some people are concerned about environmental degradation.

• People are more at risk from erosion and rising sea level in coastal locations.

Where are people concentrated?

Australia

Spain

Florida

Factors that have led to coastalisation

• Use 3 different colours for Australia, Spain and Florida to get started…

Physical factors Human factors

• Can the current rate of coastalisation be maintained?

The coastal magnet

Why is the coastal zone so favoured for development?

There are many physical factors(topography, relief

and climate) as well as human factors too. • Equable climate –Temperatures near the coast do

not vary as much as inland. Water’s specific heat capacity is much higher than the land. It takes more heat energy (and time) to warm up and water cools slowly. So coastal places are cooler in the Summer than inland places and warmer in the Winter. eg Greek Islands, Florida, Spanish Costas

• Flat, fertile land – is available in coastal areas, especially where rivers flow across their floodplains and out to sea, so it is attractive for building settlements. Alluvium deposited by the rivers in these locations is rich in nutrients so provides good farmland for generating a secure food supply. eg Cairo, Egypt.

• Building materials – stone, wood etc allow settlement construction.

• Sheltered inlets and natural harbours (which may be an upland coastline) and estuaries– shelter ships and provide suitable land for docks. eg Hong Kong, Pireaus. Larger settlements develop to accommodate the shipping trade like warehousing, processing and commerce. Some ports like Southampton handle the liners for cruise holidays.

• Flood/storm protection- mangroves/reefs are a natural form of coastal protection so people feel safe to live there. eg Caribbean

• Opportunities for aesthetic enjoyment – sea views provide tranquility and a pleasant environment to build a home or spend a day eg Dorset’s Jurassic Coast

• Recreation/tourism-Coastal areas are popular destinations for tourists. Water based recreation is fashionable eg kite surfing. Coral reefs, sand dunes and beaches draw people in large numbers. Golf courses are frequently found at the coast eg. Spanish Costas

• Employment opportunities in all sectors of the economyprimary, secondary and tertiary. • Potential for fishing – Some settlements have grownaround the fishing industry. Food security is vital. Eg Tolo.However, overfishing is problematic. Mangrove swamps arebeing cleared for the prawn industry. Fish farming in controlled conditions is also popular. • Aquaculture – shellfish, such as cockles and mussels,provide a great food source for humans and wadingbirds! eg Morecombe Bay, UK • Industry – coastal locations give access to water for cooling for industries like power stations. The sand and gravel industry also provides jobs in coastal locations.

• Accessibility/Transport – coastal access allow easyaccess for trade.• Power – Tidal power is clean and renewable. The

wind isalso often stronger at the coast so wind power is

efficienthere too. • Biodiversity – coastal ecosystems are often brimmingwith wildlife. Conservation is undertaken on significantstretches of the coast.

Timeline of coastal development1000 Early concentration of population by food security and transport at

the coast

1300 Some become seats of political and economic power and are fortified attracting more people etc

1600 European colonisation of Americas etc first settlements on coasts

1750 Industrialisation = wealth to ports

1800 Increased security of coasts encourages settlement growth and development

1850 Seaside resorts and coastal tourism takes off

1930 Paid holidays from work give big boost to coastal tourism

1950 Large scale expansion of port industries e.g. steel and ship building

1970 Exploitation of offshore resources e.g. oil and natural gas

1980 Growth of water-based recreation in estuaries, rising demand for 2nd homes in coastal areas

2000 Possible providers for wind and tidal power, greater leisure use but decline in UK based holidays

Coastalisation in the UK

• Have a look at the article entitled‘The seaside resort: a British cultural

export’

Where isBournemouth?

What is it like?

Coastalisation in the UK: Bournemouth

• Bournemouth is the largest city in Dorset, in the SW of the UK.

• Census info - population • 1851- 695 people (village)• 2001 – 163,600 (city)• 2011 – 168,100 (city)• Growth of 6.4% 1995-2005

Why so much growth?

• Not natural increase – births exceed deaths so there is a natural decrease in population

• Inward migration – mainly over 50 year olds from all over the UK!

Why are they attracted to Bournemouth?

• Climate – higher sunshine hours and milder winters

• High environmental quality – nice attractive environment near World Heritage coast

• Accessibility – amenities and only 2 hours by train from London

Q Which do you think is the most important reason and why?

Traditional?

Modern?

The growth of Bournemouth

Growth of service sector ECONOMIC BOOM

• There has been an increase in the number of jobs in the service sector in Bournemouth – banking, finance and tourism

• In 1999 – 14 889 worked in banks etc , growth to 18300 in 2003

• Barclays Bank has an IT centre and Abbey life also have offices

These are all FOOTLOOSE

Attractions1. Land is available for development (council has also granted

planning permission)2. University provides skilled graduates3. Easy access to London and other European Cities via local

airport4. Wages are lower than in SE England especially London5. House prices are lower than in most of the SE so people can

afford to buy property there

RETIREMENT BOOM

• What is the retirement boom?

• Bournemouth’s population is ageing! • Many people come to retire from the SE and downsize

their property to release their money to invest it.• The city has many facilities for the elderly eg residential

homes, clubs, bingo etc

• BUT ...• Bournemouth does retain its young people!• The University has expanded• And Bournemouth has a great night life!

The future for Bournemouth?

• Victorian buildings are now surrounded by 20th century houses.

• Coastal squeeze – the city is now squeezed between the sea on one side and rural areas inland.

• There is a greenbelt around the city.• 99% of residential property is expected to be built

on brownfield sites (18,000 new homes) • The seafront has been redeveloped • Many old hotels have been converted into flats or

student accommodation

Plenary

• Can places such as Bournemouth become ‘over-developed’?

• What is the likely future for coastal areas such as Bournemouth?
