Why Are Environmentally Sensitive Strategies Needed

Question 1

Three reasons why environmentally sensitive and sustainable management strategies are needed

Answer 1

Limitations of channelisation as a flood control strategy
To restore natural rivers and increase habitat diversity
Due increased threat of flooding from climate change

Question 2

Limitations of channelisation as a flood control strategy ( Reduce why? example instability alternative soft)

Answer 2

To reduce expensive damaging hard engineering as there are argued that they make problems worse for example resectioning causes flooding downstream making the river unstable and a soft engineering method should be used and as it takes a basin wide approach which works with the rivers natural processes

Question 3

To restore natural rivers increase habitats, diversity (What do soft engineering schemes retain and promote and allow? River restoration an example of soft engineering.)

Answer 3

Soft engineering schemes retain habitats and promote river ecosystems by allowing some flooding to take place. River restoration is restoring the river to original state before hard engineering and wetlands are an example of soft engineering that increases habitat diversity and is sustainable.

Question 4

Due to increased threat of flooding from climate change (what do effects increase? How does this affect people and what balance is needed?)

Answer 4

Effects of global warming and climate change increases storm and flood frequency which increases rest of people in properly and there is a need to bounce demands to protect against flooding as well as also planning for future generations which is difficult task
