Conflict at the coast•Examine how development and use of the coast leads to conflict and

competition for space•Explain why the geology of the Dorset coast is significant

•Describe the effect of geology on landforms in Dorset and give named examples of different landforms

•Use a conflict matrix to explain how World Heritage status can lead to conflict

•Describe the problems that tourism can cause•Identify the advantages and disadvantages of the Boscombe surf reef

Development and use of the coast

• Competition for land often results in conflict

What does this mean?

Development and its consequences

Competition for space

• Until demand begins to exceed supply usually competing users share land.

• Those that can pay the most occupy the sites that best suits them.

• Tourism, heavy industry, agriculture and fishing compete for coast space.

• Competition will result in some conflict.

Conflict matrix of coastal users

• Quarrying is the least compatible.• Commerce (like administration and

finance) is the most compatible land use as it is needed by most, if mot all of the other users.

• Perhaps the most vulnerable of the land uses is the nature reserves, where there is significant aesthetic, historical, archaeological or geological value.

Stakeholders• These are individuals, groups or

organisations that have an interest in the development or outcomes of a particular project. They may be involved financially or emotionally.

Conflict and Tourism: Jurassic coastline – a World Heritage

site in Dorset and East Devon

jurassic.flv

The Jurassic Coast

• 150km from East Devon to Dorset has become Britain’s first World Heritage Site due to its geologically significance

• Rocks are described as a ‘journey through time’ as they span the Triassic, Jurassic and Cretaceous periods (ie from 250 million to 65 million years ago).

• There are sand dunes and sandy beaches as well as small isolated bays

and dramatic plunging cliffs. • Many ammonite fossils are visible as the coast

erodes away

Ammonite

• The World Heritage status extends from the cliff top to the low watermark

• It does not include the developed waterfronts of the towns along the way eg Swanage, Weymouth

• See Oxford Dorset photocopy

Rock Structure/Geology

There are 2 main types of coasts:• 1) Concordant Coast• 2) Discordant Coast• They are determined by rock

structure (geology) and form where there are alternate bands of resistant and less resistant rock.

Concordant Coasts eg Lulworth Cove

• Occur where the rock structure is parallel to the coast.

• Hard bands of rocks protect the softer rocks from erosion.

• (If there is local tectonic movements or sea level change (eustatic) then islands may form when separated from the mainland by drowned valleys eg Croatia’s Dalmation Coast)

Discordant Coasts eg Swanage

• Occur where the coast ‘cuts across’ the rock structure. Eg Swanage Bay.

• Bands of differing rock type that run perpendicular to the coast at a right angle.

• Headlands and bays occur on discordant coastlines due to the variation in rock type hard rock (more resistant) outcrops named headlands and soft (less resistant) eroded rock forming bays between two headlands.

Physical and Human links?

• Why have the physical landforms along the Jurassic Coast lead to the area being a hotspot for tourists?

• Why are they attracted to this coastline?

Why conflict exists?

• From page 184 – why does conflict exist?

What conflicts can occur?

• Using the conflict matrix and p.184/185 identify potential conflicts with explanation of your decisions

Further Conflict? – Boscombe surf reef

Boscombe Artificial Reef

• Completed in 2008 on 1 hectare of land

• Forces waves to break out at sea due to placement of geotextile sand bags.

• £1.1 million cost approximately• Surf waves produced at 4m high• Attracts 10 000 surfers/year• Expected earnings of £10 million per

year
