Placing hard strategies (e.g. rip-raps) at the beach is not appropriate because ...

• the major land use there is recreational which is of low economic value

• there would not be many people at the beach especially during storms.

• However, the construction cost of rip-raps is high.

• So it is not c___-e________ to carry out this strategy .

Placing hard strategies (e.g. rip-raps) at the beach is not appropriate because ...

• On the other hand, rip-rap are large boulders. They will affect the access to the beach. People may find it hard to carry out different kind of water sports, e.g. swimming, surfing.

• The beach will also look awkward. This will affect the natural scenery. People may not use the beach anymore.

Fill in the Blank

Placing hard strategies (e.g. rip-raps) at the beach is not appropriate because ...

major land use = recreational = low economic value However, the construction cost of rip-raps is high. So it is not ____________________ to carry out this strategy .

Open Ended

Can you think of any other reasons?

Discussion points:

• cost-effectiveness: e.g. construction cost of rip-raps VS economic value of the land use

• Impact on the present use: e.g. Will the access to the beach be restricted if we place rip-raps? If so, what activities will be affected? Any other further impacts?

• Does it match with the natural environment? Will it be too awkward?
