Impact evaluation for conservation

Conservation and restoration spend public and private money on the expectation that interventions work. Causal inference tests that expectation, estimating what protected areas, payments, restoration and policy changes achieved compared with what would have happened without them. Without that comparison, background trends are easily mistaken for success.

What causal inference and impact evaluation does here.

Causal inference and impact evaluation develop methods to determine whether and how interventions or exposures cause outcomes. They separate genuine effects from correlation. In biodiversity and nature, climate and hazards and oceans and coasts, causal inference shows which kêmkirina xetera measures actually work. It supports allocating resources toward interventions with demonstrated effect across connected risks. The canonical description is on STEM Commons.

Protected area effectiveness

Protected sites are matched to unprotected sites with similar slope, remoteness and pressure, and differences in forest loss or species trends are estimated with sensitivity to hidden bias.

Restoration and payment programme evaluation

Difference-in-differences and synthetic control designs compare enrolled land with comparable land outside a programme, before and after it starts.

Policy and supply-chain commitments

Staggered adoption of moratoria, regulations or zero-deforestation commitments is used to estimate effects on clearing and on displacement of clearing to other areas.

Impact evaluation for conservation: PRISMA 2020 review reporting

PRISMA 2020 is a reporting guideline for systematic reviews; the steps follow its checklist, not a mandated sequence, and no Nexus document adopts it.

  1. 01 Plan

    1. 01Registration and protocolRecord · The review teamThe guideline asks for registration details, access to the protocol and any amendments.
    2. 02Eligibility criteriaRecord · The review teamThe guideline asks for the inclusion and exclusion criteria and how studies were grouped.
  2. 02 Find and select

    1. 03Search: sources and strategiesStep · The review teamThe guideline asks for the information sources and the full search strategies. It does not fix which sources are used.
    2. 04Selection of studiesStep · The review teamThe guideline asks how studies were judged eligible, including how many reviewers screened. It does not fix the number of reviewers.

    2. 07Risk of biasStep · The review teamThe guideline asks for the methods and tools used to assess risk of bias.
    3. 08SynthesisModel · The review teamThe guideline asks for the effect measures and the synthesis methods. It does not prescribe meta-analysis.
    4. 09Certainty of evidenceStep · The review teamThe guideline asks for the methods used to assess certainty, and reports the result per outcome. It does not name a grading scale.

rêzeya Pergalên StratejîkOutline of an externally published reporting guideline, not a Nexus process and not a record of operation. PRISMA 2020 mainly covers reviews of intervention effects. No Nexus page names it. Every programme is at service level R0.

06Erêkirin

How results are checked.

Identification assumptions are probed through placebo tests, falsification checks and sensitivity analysis. Replication across settings tests external validity.

Kontrol bikinHow it is done
Covariate balanceTreated and comparison units are compared on observed characteristics before effects are estimated
Placebo and pre-trend testsEffects are tested in periods and places where none should exist
Sensitivity to hidden biasResults state how strong an unobserved confounder would need to be to change the conclusion
Spillover and leakageNeighbouring areas are examined for displaced pressure

Unobserved confounding and spillovers can bias estimates. Effects found in one context may not transfer to another.

08Stewardship

What are the limits of causal inference and impact evaluation in this field?
Unobserved confounding and spillovers can bias estimates. Effects found in one context may not transfer to another.
How are results checked?
Identification assumptions are probed through placebo tests, falsification checks and sensitivity analysis. Replication across settings tests external validity.
Are the values on this page real?
The data names, roles and checks are real descriptions of practice. The canvas shows a design of the method’s use, not a run; no result is reported here.
Where else is this method applied?
Çavdêrxaneya canonical method page lists every platform that applies it.
