How do community-level climate change vulnerability assessments treat future vulnerability and integrate diverse datasets? A review of the literature
Bibliographic record
Abstract
Community-level vulnerability assessments (VAs) are important for understanding how populations experience vulnerabilities to climate change in different ways given local socioeconomic and environmental factors. Despite recent expansion in the literature that evaluates vulnerability at the local level, approaches to understanding future scenarios and to integrating climatic and nonclimatic factors are inconsistent and often lack clear methodological information. This study utilized systematic review methods to characterize and compare future scenarios and the integration of climatic and nonclimatic stimuli in community-focused VAs published over the last five years. Five common methods for assessing future dimensions of vulnerability were characterized. Key challenges regarding sources and scales of information were highlighted alongside methods to integrate data spanning climatic and nonclimatic information at scales ranging from local to global. The majority of VAs considered current and past vulnerability; few VAs incorporated future scenarios and these studies focused on future climatic conditions while largely overlooking changes in nonclimatic drivers of vulnerability. Approaches to evaluate future dimensions of vulnerability included climate model projections, socioeconomic model projections, temporal analogue approaches, longitudinal approaches, and local perceptions. These methods often failed to capture the dynamic interactions between variables through time, as future impacts are unlikely to follow previous patterns of change. To combine datasets of different scales, VAs created vulnerability indices, overlaid spatial datasets, or used expert judgement. These approaches tended to aggregate local characteristics to the regional level at the expense of community specificity. There is a need for methodological advances to assess future scenarios and to combine datasets in the field of community-level climate change VAs to make these studies more responsive to local realities and relevant to the development of climate change adaptation strategies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
