When an exam question asks you to "evaluate the effectiveness" of ecosystem management, you need a framework to structure your judgement. Use CLEARS:
- C — Cost: Is the approach financially viable? Who pays? Is it affordable for an LIC? Does it generate income as well as spending it? (Knepp: yes — £2.5m tourism income. REDD+ in DRC: payments often don't reach communities.)
- L — Local people involvement: Do local communities benefit and participate? Or is conservation imposed from above? (REDD+ fails here. Knepp works here. The Barrier Reef generates economic benefits for Queensland.)
- E — Effectiveness at reducing ecological threat: Does it actually work? Does biodiversity increase? Does the ecosystem recover? (Knepp: demonstrably yes. Barrier Reef: local pressures reduced but global threat continues.)
- A — Addresses the root cause: Does it deal with WHY the ecosystem is under threat, or just treat the symptoms? (REDD+ attempts to, by making standing forests economically valuable. Barrier Reef zoning does not address climate change.)
- R — Replicability: Can this approach be applied elsewhere, at scale? (Knepp rewilding: no, requires wealthy landowner. REDD+: yes, in principle. Marine zoning: yes.)
- S — Sustainability long-term: Will this still be working in 50 years? Does it require continued external funding, or does it become self-sustaining? (Barrier Reef management: sustainable only if climate change is addressed. Knepp tourism: self-sustaining once established.)
Memory hook: "Is this management approach CLEARS?" — Cost, Local people, Effectiveness, Addresses root cause, Replicability, Sustainability.
In a 6–8 mark exam answer, pick two or three criteria from CLEARS and apply them to your named example. In an 8-mark "to what extent" answer, use CLEARS to compare two different approaches and reach a justified conclusion.
