G2 - coastal landscapes and change 4

?
economic losses from coastal recession
loss/damage to property (houses, businesses and farmland). dependent on the lands use and location
1 of 18
social losses from coastal recession
relocation (break up of communities, livelihoods, memories). loss of livelihoods (no jobs, financial problems)
2 of 18
environmental refugees
those who have been forced to move from their homes due to environmental disasters/climate change . EG MALDIVES POPULATION
3 of 18
hard engineering approaches to managing the risks associated with coastal recession
groynes. sea walls. rip rap. revetments. offshore breakwaters. economically costly and directly alter coal processes and systems- unintended consequence.
4 of 18
soft engineering approaches to managing the risks associated with coastal recession and flooding
beach nourishment, cliff regrading and drainage, dune stabilisation. work with physical processes and systems to protect classroom and manage the risks caused by changes in sea level
5 of 18
sustainable coastal management
managing the wider coastal zone in order to cope with future threats (increased storm events and rising sea level). can lead to local conflicts due to differences in interests, relocation may be needed, uncertainty and changes in plans.
6 of 18
Inter Coastal Zone Management (ICZM)
a holistic approach to managing coasts, involving all stakeholders and working with natural processes and using 'adaptive management". works w the concept of sediment cells.
7 of 18
Shoreline Management Plans (SMP)
a large scale report assessing the risk associated with coastal processes. aims to reduce to risks to people, property and natural environment based around the shoreline only. each SMP covers a sub-cell within a sediment cell.
8 of 18
coastal management strategies
hold the line, advance the line, retreat the line, no active intervention
9 of 18
hold the line
build/maintain coastal defences so that the position of the coastline remains the same over time
10 of 18
advance the line
build new defences further out to sea than existing ones- promotes land reclamation
11 of 18
retreat the line (managed realignment)
build no defences, but move people away from the coast. also can manage the process to direct the retreat to certain areas
12 of 18
factors affecting decision making in management
economic value of assets that could be protected. cultural and ecological valley of land. pressure from communities (campaigns/protests). social value of communities.
13 of 18
cost-benefit analysis
used to help decide if defending a coastline from erosion/flooding is economically justifiable.
14 of 18
environmental impact assessment
identifies the short term impacts of construction on the coast and the long term impacts of building new sea defences/changing type of policy.
15 of 18
policy decision leading to conflicts.
management plans cover entire SMP areas, so some areas are protected whilst others are not - conflict. local councils and governments (DEFRA) have limited resources and so no all areas can be protected. BLACKWATER ESTUARY, ESSEX
16 of 18
players in coastal decision making
homeowners, local authorities, environmental pressure groups.
17 of 18
mitigation defintion
reducing the severity/seriousness or painfulness of something.
