Question 23 WAEC_MODEL_QUESTIONS_VOL1 • 2018 • GEOGRAPHY • objective

A coastal town suffers on average each year from flood damage costing ₦45 million (standard deviation ₦12 million) and from coastal erosion costing ₦8 million (standard deviation ₦3 million). A proposed Integrated Coastal Management (ICM) plan requires an upfront investment of ₦30 million, reduces expected flood damage by 40 % and erosion loss by 25 %, and adds an annual maintenance cost of ₦2 million. Ignoring discounting and using only expected values, should the town adopt the ICM plan over a 5‑year horizon? Show the total expected cost with and without the plan and state the decision.

Answer Options

A. No; the plan saves only ₦5 million over 5 years, insufficient to adopt.
Correct Answer B. Yes; the plan saves ₦60 million over 5 years, so it should be adopted.
C. No; the plan costs ₦15 million more over 5 years, so it should not be adopted.
D. Yes; the plan saves ₦30 million over 5 years, so it should be adopted.
Correct Answer
B
Correct Option:
Yes; the plan saves ₦60 million over 5 years, so it should be adopted.
