1

Where are the Sundarbans?

Bangladesh (mainly) and India

2

Define Monsoon

A seasonal reverse of wind direction heralding a change from a dry to wet season

3

More than …..% of the population live in an area impacted by a monsoon climate

60%

4

India receive …% of their rainfall in the Summer monsoon

90%

5

How are monsoons formed?

Land heats up quicker than water so heat rises over the land of India
An area of low pressure is formed
The direction of the prevailing winds changes so moist air goes over land

6

What is a river delta?

low, flat land, sometimes shaped like a triangle, where a river divides into several smaller rivers before flowing into the sea

7

List 5 coastal processes in the Sundarbans

Tidal action (main)
Erosion
Monsoon winds
Increasing sea levels
Instability of islands

8

Define sustainability

Meet the needs of the present without compromising the needs of the future.

9

Why can mangroves live in the sea?

Roots can filter out the salts

10

Name 3 benefits of mangroves (not goods)

Roots are home to fish
Decrease erosion
Reduce sediment run off from land

11

Name 4 services the Sundarbans provide

Fuels
Protection (erosion)
Provision (climate control and breeding grounds)
Value

12

Name 4 goodscthe Sundarbans provide

Food
Textiles
Medicine
Construction material

13

Name the two types of opportunities into the Sundarbans

Goods and Services

14

Name 5 natural risks to the Sundarbans

Coastal flooding
Cyclones
Salt in soil
Instability of islands
Remote

15

Name 5 human risks to the Sundarbans

Over exploitation
Destructive fishing techniques
Lack of awareness of importance
Resource use conflict
Convert wetland to settlements and agriculture

16

Define resilience

Being able to cope with the challenges the environment presents

17

Define mitigation

Reducing the severity of hazards and other issues

18

Define adapttaion

Adjusting behaviour to fit the environment

19

List 4 challenges of the Sundarbans

Increased frequency and intensity of floods

Increase salinity levels of soil

Pesticide use affect water quality

Embankments encourage silt -> river level rises

20

3 ways people have adapted to the Sundarbans

Build houses of stilts

Sustainable - non-intensive farming techniques and ecotourism

Salt-tolerant rice (AO3 - reduce biodiversity and vulnerable to pests

21

3 ways people have mitigated to the Sundarbans

3500km of embankments built

Protect mangroves and replant in areas

Cyclone shelters

22

4 ways people have been resilient to the Sundarbans

Better roads and bridges

Increase food security by giving £

Increase access to clean water

Electricity in more areas and solar panels

23

What do USAID do to help? (4)

Monitor tiger population
Harvest crops efficiently
Sell excess crops
Raise fish

24

Describe the ICZM

Integrated coastal zone management
Coastal people peruse sustainable economic development

25

What does the ICZM do? (4)
(Sundarbans)

Improve rural livelihood
Manage fresh water resources
Develop tourism and fishing sector
Improve infrastructure and social provision

26

Define mangrove

Semi-marine tropical species of tree that grows in shallow water with roots above the surface.

27

Describe the key development - cyclone protection (2)

2000+ cycle shelters
Social centre when not in use

28

AO3 - Describe the key development - cyclone protection (1)

Not enough for scale needed

29

Describe the key development - coastal protection (2)

5000km of embankments
123 barrier dams

30

AO3 - Describe the key development - coastal protection (3)

Reduce flow of tidal
Increase sediment deposition
Increase water logging
