Flashcards in Case Study: Contrasting Stages of Economic Development to Illustrate Mitigation and Adaptation: Bangladesh Deck (22)
Stage of economic development
Most of the country occupies what?
Ability to adapt limited by what?
2014 GDP per capita
142nd out of 187 countries
Environmental Impacts and Threats: Mangroves
Protect against storm surges
Valuable ecological services
Threatened by rising sea level and human activity like clearance for agriculture and fish farming
Environmental Impacts and Threats: Salination
Rising Sea level will increase the contamination of groundwater and soil
by 2100, 600,000 ha of agricultural land could be too highly salinized for cultivation
Socio-Economic Impacts and Threats: Floods
Average elevation above sea level = 4-5m
10% of country 1m above sea level
Floods make bredding sites for insect vectors = disease
How many people live less than 1m above sea level?
How much of the country floods every year?
Socio-Economic Impacts and Threats: Drought
Drinkable water becomes scarce
Socio-Economic Impacts and Threats: Cyclones: In the last 25 years how many of worldwide deaths from cyclones were in Bangladesh?
Socio-Economic Impacts and Threats: Cyclones
Still recovering from 200-7 and 2009 cyclones
Socio-Economic Impacts and Threats: Why is there now more exposure to cyclones?
Rising sea level, more intense cyclones, and growing population.
Socio-Economic Impacts and Threats: Mitigation
No strategies as Bangladesh regards the reduction of GHGs as the responsibility of the developed world
Adaptation - why is it hard?
60 million people live in poverty
Adaptation - why are community-based solutions important?
Large population with limited resources
Adaptation - Flood protection
$2 billion embankment to improve 3500km of dykes
Upgrade storm surge warning systems
Build cyclone and flood shelters
Raise houses an platforms 1m above flood levels
Platforms for livestock
Funded by a loan from the World Bank
Adaptation - Coastal Mangroves
Communities encouraged to conserve them
Adaptation - Glacier Retreat and Water Supply
Drip irrigation, rainwater harvesting, storage reservoirs
Adaptation - Agricultural Practices
Floating vegetable gardens on rafts of water hyacinth or bamboo
