Coastal Zone Management Questions and Answers

Answer: C

Correct answer: requiring that a route be maintained or diverted, not removed

Where a public right of way or a coastal access route crosses the works, the scheme must keep it open, divert it, or provide an equivalent - it cannot simply extinguish it. In practice this means ramps, steps and a route along or behind the new structure, which affects both the design and its cost. It does not prohibit construction, nor does it guarantee access to the sea bed.

Answer: D

Correct answer: A-2, B-4, C-1, D-3

Each use represents a distinct interest that a coastal decision may help or harm. Commercial fishing is a livelihood dependent on the resource itself. A port needs a navigable channel maintained. Recreation and tourism depend on the beach and the amenity of the coast. Nature conservation is concerned with habitat and species. A scheme that serves one may damage another, which is why they are identified separately.

Answer: A

Correct answer: Both A and R are true, and R is the correct explanation of A

Both are true and the reason states the difficulty. The coast is a narrow strip on which fishing, shipping, recreation, conservation, housing and defence all make claims, and there is not room to satisfy them all. The engineering settles what is possible; deciding whose interest yields, and on what terms, is a matter of process and negotiation, and it is where most schemes actually succeed or fail.

Answer: B

Correct answer: allocates uses across the sea area rather than the shoreline

Marine spatial planning works seaward, allocating space among fishing, shipping, aggregate extraction, wind farms, cables and conservation across the sea area. Shoreline management planning works along the shore, assigning a defence policy to each frontage. The two must be consistent with each other, but neither replaces the other, and neither removes the need for environmental assessment of individual proposals.

Answer: C

Correct answer: 1 and 2 only

Statements 1 and 2 are correct: marine planning allocates space among competing uses, and it must be consistent with the shoreline policies where the two meet. Statement 3 is wrong - they address different areas and different questions, and a marine plan says nothing about whether a given frontage is to be defended or allowed to retreat.

Answer: D

Removing material changes the bathymetry that waves propagate over. Licensing requires an assessment of the effect on the coast itself. Bathymetry governs how waves reach the shore. Licensing therefore requires a coastal assessment.

Answer: A

Both are true and the reason gives the mechanism, and sediment supply may also be affected. Exclusion zones are commonly imposed close to a sensitive coast. Sediment supply may be affected as well. Exclusion zones protect the more sensitive frontages.

Answer: B

Scenario planning keeps options open under genuine uncertainty. Adaptive pathways allow a decision to be revisited as the evidence develops. Scenarios keep the options genuinely open. A single forecast would be false precision.

Answer: C

Correct answer: A-2, B-4, C-1, D-3

The four concepts belong to adaptive planning under uncertainty. A pathway is a sequence of decisions with review points rather than one commitment made now. A trigger point is the observed threshold - a rate of erosion, a sea level, a defence condition - that prompts the next decision. Lock-in is a choice that forecloses later alternatives. A no regrets measure is one worth taking whatever the future proves to be.

Answer: D

Correct answer: Both A and R are true, and R is the correct explanation of A

Both are true and the reason explains the concern. A large fixed defence commits the coast to holding that line: it becomes politically and practically very hard to abandon, it encourages development behind it that raises the value at risk, and it forecloses realignment that may later be the only affordable option. Keeping options open therefore has a value of its own under an uncertain sea level.
