Question
Define coastal erosion.
Answer
The **wearing away and removal** of cliff or beach material by waves.
Question
Define coastal flooding.
Answer
The sea **covering low-lying land**, often during a **storm surge**.
Question
What is hard engineering?
Answer
**Built defences** that resist the sea — sea walls, groynes, rock armour.
Question
What is soft engineering?
Answer
**Working with nature** — beach nourishment, dune planting, salt marsh.
Question
What is managed retreat?
Answer
Deliberately **letting the sea flood low land** instead of defending it, often making salt marsh.
Question
Define a stakeholder (coast).
Answer
Any **person or group** with an interest in how the coast is used or protected.
Question
Why does a sea wall cause conflict elsewhere?
Answer
It traps/reflects sand, **starving the next beach down-drift**, so that community erodes faster and objects.
Question
Why is managed retreat so contested?
Answer
It is cheap and sustainable but means **losing homes and farmland**, so residents and farmers resist it.
Question
Great Barrier Reef — conflict?
Answer
Marine-park **zoning** separates fishing, diving and conservation; tourism, fishers and inland farmers (run-off) all clash over access.
Question
The Sundarbans — conflict?
Answer
Mangroves are a natural storm defence, but locals clear them for shrimp ponds and firewood, weakening the very barrier that protects them.
Question
Why do coastal conflicts resist resolution?
Answer
Defending one place harms another, money is limited, and **stakeholder power is unequal** — wealthy areas are defended first.
Question
What does a top [10] Examine answer need?
Answer
Hard + soft + managed-retreat strategies, two+ stakeholder conflicts, their power/perspectives, a named coast, and a justified conclusion.
