Unit 2 – Coping with the pressure
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
Time
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.

coastal tourism and recreation
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.

Ecology
• What does this mean?
• Why is Dorset important ecologically?
• Page 182 Oxford photocopy
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
