carbon Flashcards
what causes decline in ocean health
bleaching
acidification
this causes marine food webs to change eg fish stocks declining
why is tourism under threat due to declining ocean
Caribbean countries where coral reef - showing signs of degredation - attract scuba divers but now that’s not possible
rising sea level threatens tourism in coastal infrastructure - Maldives Seychelles
what questions arise from uncertainty over the future of carbon
population growth will it level off?
resilience of carbon growth - limited capacity?
will fossil fuels be replaced?
What is Adaptation
living with the problem not solving
Mitigation
tacking root problem
Name Adaptation Strategies
Water Conservation and Management
Land Use Planning
Flood Risk management
Benefits of Water Conservation
fewer resource used - less groundwater abstraction
attitudinal changes operate on long term basis - more recycled water
Costs of Water Conservation
efficiency and conservation cannot match increased demands for water
changing in cultural habits of large water footprint needs promotion and enforcement by governments
Land Use Planning Benefits
soft management
enforcing strict runoff controls and soakways
Costs of land use planning
strong governance, enforcement and compensation
public antipathy
abandoning high risk areas and land use resettling often unfeasible - mega cities in Dhaka, Bangladesh
Benefits of Flood Risk Management
hard management - localised flood defences
simple changes reducing flood risk
reduced deforestation and more afforestation upstream to absorb water
Costs and Risk of Flood Risk Management
constant maintenance is needed for hard management
debate over funding sources - in times of economic austerity
