Intersectionality of Disability and Climate Change Threats: Identifying the Unique Vulnerabilities Faced by Persons with Disabilities in Abia State Nigeria Using the Subgroup Chart Technique

This exploratory study of 104 persons with disabilities (PWDs) investigates the specific climate change challenges they experience in a developing country, covering the three senatorial districts in Abia State, Nigeria. Eight impairment categories across age range, gender, and location are considered. A subgroup chart technique and two-way analysis of variance test are applied. We further use the psychometric paradigm and cultural theory of risk to explain the perceived–actual climate threats relationship. Heat stress is a critical concern across all districts, mostly impacting clusters like people with albinism, who are deaf-blind, have hearing impairments, and leprosy survivors. Flood threats are extreme in Abia North and South zones but less so in Abia Central. Air pollution is a major threat in Abia North. These perceptions broadly mirror actual climate risks, albeit expressed with heightened severity, emphasizing the critical roles of vulnerability and accessibility. No gender-based differences emerge. Effective climate resilience strategies must capture region-specific targeted interventions.
