Case Studies Flashcards
Bangladesh- flooding
High population density
Low land height
Lives on flood plains
Snow from Himalayas melts into rivers
Deforestation
Islands sinking from rise in water levels
Mangroves in danger from flooding and deforestation
Storm javier- Norfolk
2 killed, 18,000 evacuated
1,400 homes flooded
Total economic loss £100 million
Coastal defences breached
Impacts prevented due to improved flood defences, improved forecasting and efficient evacuation
Maldives- flooding
Low lying above sea level
Sea wall built around capital
In the future, use mangroves as a natural defence
Management, hold the line
Odisha, India- flooding, which managment?
Overall plan- hold the line
Why management in odisha
Rapid urban industrialisation
Coastal and seabed mining
Coastal erosion
Rising sea levels
What management in odisha has taken place
Holding the line:
ICZM project
Public constitutions
Organisations with stakeholders
Holderness coast
Powerful destructive waves
Sea floor is deep
Narrow beaches
HC- Spurn Head
Spit
Hold the line management
HC- Flamborough head
Headland
Areas with hold the line managment at holderness coast (groynes, rock armour)
Hornsea
Withersea
Colorado river- California
Climate change
Invasive species- beetle, trout
Population growth
100 dams, hydroelectricity
Humans taking away mineral resources
-gov shut down national park service, dam building on hold
-reducing water use and planting trees
Sahel drought
Rainfall dependent on ITCZ
Locus infestation 2004
Overgrazing
High population
Migration
Globalisation
Australian drought
El Niño caused drought
High population
Water needed for agriculture production
River Nile
Ethiopia, Sudan, eygpt
Nile river basin commission
Ethiopian renaissance dam
Guardians of the Nile ( Egypt and Sudan)
Integrated water resources management
Gorge dam China (pos and neg)
Pos:
Flood control
Emissions reduction
Prevent construction work from causing environmental pollution
Neg:
Weight of tons of water could cause earthquake
Could cause rapids it built up in reservoir
Uk energy
Less energy on household and industry and more on transport
Huge potential wind power resource
London array- large offshore wind farms
Nuclear- expensive, gov not fund directly
Russia energy
Nord stream- connects Russia to Europe
Yamal- Europe pipeline
Gazprom- 70% Russian gas is 18% of the worlds gas, exporting
Canada tar sands
Tar sands could meet 16% of North America’s oil needs by 2030, offering energy security to Canada and the USA (70% of Canadian oil is exported to the USA).
The work related to this is vital for local and national economies.
