Stage of economic development

LIDC

2

Most of the country occupies what?

Ganges-Brahmaputra Delta

3

Ability to adapt limited by what?

Poverty

4

2014 GDP per capita

$2364

5

HDI

142nd out of 187 countries

6

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

7

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

8

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

9

How many people live less than 1m above sea level?

20 million

10

How much of the country floods every year?

70%

11

Socio-Economic Impacts and Threats: Drought

Drinkable water becomes scarce

12

Socio-Economic Impacts and Threats: Cyclones: In the last 25 years how many of worldwide deaths from cyclones were in Bangladesh?

60%

13

Socio-Economic Impacts and Threats: Cyclones

Still recovering from 200-7 and 2009 cyclones

14

Socio-Economic Impacts and Threats: Why is there now more exposure to cyclones?

Rising sea level, more intense cyclones, and growing population.

15

Socio-Economic Impacts and Threats: Mitigation

No strategies as Bangladesh regards the reduction of GHGs as the responsibility of the developed world

16

Adaptation - why is it hard?

60 million people live in poverty

17

Adaptation - why are community-based solutions important?

Large population with limited resources

18

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

19

Adaptation - Coastal Mangroves

Communities encouraged to conserve them

20

Adaptation - Glacier Retreat and Water Supply

Drip irrigation, rainwater harvesting, storage reservoirs

21

Adaptation - Agricultural Practices

Floating vegetable gardens on rafts of water hyacinth or bamboo

22

Adaptation - Disease

Government climate change and health promotion unit to research new diseases and educate people anout the risks
