Why can combining nature-based solutions with traditional grey infrastructure be effective?
Answer and explanation
Correct answer: Their combined strengths may reduce risk and cost
Hybrid approaches use the protective functions of ecosystems together with the predictability or structural strength of engineered works. For example, mangroves can absorb wave energy and trap sediment while a sea wall provides additional defence at critical locations. Such combinations may spread risk, create habitat and reduce maintenance or construction pressure, although design must be site-specific. Thus A is the correct rationale.
