Climate adaptation
Maladaptation
Actions taken to adapt to climate change that inadvertently increase vulnerability, emissions or risk — for the actors themselves or others — now or in the future.
Definition
Maladaptation refers to adaptation actions that lead to increased risk of adverse climate-related outcomes, increased vulnerability to climate change, or diminished welfare, now or in the future (IPCC AR5). The concept, elaborated by Barnett and O'Neill (2010), includes measures that increase emissions, disproportionately burden the most vulnerable, have high opportunity costs, reduce incentives to adapt, or lock in inflexible pathways.

Overview
What it means
Examples include sea walls that encourage development in hazard zones, air conditioning that raises emissions and energy poverty elsewhere, and irrigation that depletes shared aquifers. Maladaptation often emerges from short planning horizons and siloed decisions.
How it is used
Adaptation planners and funders screen projects for maladaptive risks; national adaptation plans and climate-risk assessments increasingly require maladaptation analysis.
Why it matters
Poorly designed adaptation can waste scarce climate finance and entrench vulnerability; avoiding maladaptation is essential to effective, equitable adaptation.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.
Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.
Only an editor-accepted synthesis changes the public page. Reviewer identities are shown only with consent and an editorial decision to attribute them.
Submitted reviews stay private until an editor decides whether to accept and attribute them.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
