because of the low lying nature of the country

Question 10

that’s four major threats to the sundarbans

Question 24

what’s the most major factor (environmental) of cyclone Sidr

Answer 24

Nearly 1/4 of the mangrove forest of the Sundarbans was destroyed by the storm surge and strong winds. It was estimated the forest could take 40 years to recover. This was the most major impact as mangrove Forest, playing important role in absorb the energy of tropical storms and shelter in vulnerable areas behind them.

Question 25

What is six different types of land-use found in the coastal area of Bangladesh?

salt farming
industry
tourism
settlement and infrastructural

Question 26

coastal flooding
cyclones
high levels of salinity in the soil
instability of the islands
accessibility and remoteness
human eating tigers

Question 27

what’s 6 main human challengers within the sundarbans

Answer 27

-over exploitation of coastal resources from vulnerable habitats
-conversion of wetlands to intensive agriculture and settlement
-Destructive fishing techniques
-Lack of awareness of the environmental and economic importance of the region
-Resources conflict
-Lack of awareness of Coastal issues by decision makers

Question 28

why does agriculture occupy the coastal areas of Bangladesh

Answer 28

-race farming has been one of the most important activities in Bangladesh
- fertile alluvial soil is deposited within the freshwater a strong environment. Provide excellent conditions for year-round cultivation farms
-often small and produce low incomes

Question 29

why does fishing occupy a lot of coastal areas of bangladesh

Answer 29

coastal location and tropical waters provide excellent opportunity is fission 445,000 tons of fish were harvested in 2003
However, shrimp farming in the south-east mangroves have become increasingly important due to the global demand, so people of Bangladesh saw this as an opportunity

Question 30

why does industry occupy a lot of the coastal areas of Bangladesh?

Answer 30

A variety of industrial activities, and I’ll set an apostle areas to take advantage of flat. Expensive land could access the shipping routes and a large supply of cheap labour.
There are only few sometimes no regulations in relation to pollution and industry can take advantage of this in deposit waste into the sea

Question 31

Why does settlement and infrastructure occupy the coastal areas of Bangladesh?

Answer 31

settlement and infrastructure are developing in the coastal areas, increasingly because of new areas to develop
New job opportunities are increasing for the rapidly growing population
And example of an area could be a Chittagong in the south-east

Question 32

What is four issues in terms of conflict in management that arise from the development of coastal areas

Answer 32

-The rapid development of shrimp farming has conflicted with traditional farming
-Shrimp farming, and the environment
-The industrial development conflicts with the environment and human rights
-Agriculture in settlements conflict with the environment

Question 33

why is the rapid development of shrimp farming conflict with traditional farming a problem?

Answer 33

shrimp farming has displaced rice, farmers further inland, which is created major disputes between people
Shrimp farming has caused freshwater areas to pick up of the line which prevents production of rice. It has also polluted fresh drinking water supplies. Million people have to travel further for water.

Question 34

Why is shrimp farming and the environment a problem

Answer 34

shrimp farming has led to the loss of large areas of natural mangrove swamps, which are important ecosystems
Not only do they support huge amounts of fish, but provide timber fuelwood and material for industry. They also provide a natural buffer for tropical cyclones

Question 35

why is industrial development conflicting with the environment and human rights a problem

Answer 35

A particular industry, which is a major concern is ship breaking
This is where large vessels are deposited on the coast, ready to be broken down by young workers who are exposed to extremely poor working conditions long hours unprotected from hazardous, materials, chemicals, toxins, and heavy materials they are regularly killed

Question 36

why is agriculture/settlements conflicted with the environment a problem

Answer 36

pollution comes from agricultural pesticides, fertilisers and untreated waste from an ever increasing settlements. This leads to decline fish, stocks and other marine organisms.
