摘要

Background

Climate variability accelerates moisture induced deterioration, concrete carbonation, reinforcement corrosion, and biological colonization in building envelopes across tropical, semi-arid, and coastal Nigerian bioclimatic zones. While hygrothermal modeling and pathology assessments advance, empirical links between climatic stressors, material degradation, and rehabilitation outcomes remain scarce in developing contexts.

Purpose

This study investigates hygrothermal behavior and degradation pathways, including carbonation kinetics, chloride induced corrosion, biological colonization, and moisture driven pathologies, across Nigeria’s three zones. It emphasizes diagnostic methods and adaptive rehabilitation under variability.

Methods

Mixed methods included 908 surveys from pathology specialists, conservation experts, and managers in coastal (Niger Delta), semi-arid (Kaduna), and tropical (Cross River) zones. Analyses comprised descriptive statistics, chi square tests, correlations, multiple regression, and thematic analysis of 847 open ended responses.

Results

Policy constraints (β = − 0.29, p < 0.001) and ecological uncertainty (β = − 0.21, p < 0.001) hindered decisions, while institutional support (β = 0.34, p < 0.001) and adaptive governance (β = 0.27, p < 0.001) improved management. Model R² = 0.49. Zone specific pathologies: coastal chloride corrosion (68.3%), sulfate attack (54.7%); semi-arid thermal cracking (61.2%), soil failures (48.9%); tropical bio colonization (72.4%). Coastal governance challenges strongest (β = − 0.31).

Conclusion

Zone tailored diagnostics address bioclimatic pathologies like coastal corrosion, semi-arid fatigue, and tropical biodeterioration. Institutions need scenario planning and non-destructive techniques, prioritizing coastal vulnerabilities.
