Effective disaster risk reduction (DRR) in resource-constrained rural contexts increasingly depends on communities' ability to mobilize local resources. This study examines the disaggregated impact of three local resource mobilization constructs financial, material, and human resources on corresponding phases of DRR: preparedness & early warning, mitigation & adaptive capacity, and response effectiveness & recovery. A cross-sectional survey design was employed, collecting data from a stratified random sample of 316 DRR stakeholders (local officials, committee members, and active volunteers) in Bulambuli District, Eastern Uganda. Data were analyzed using Pearson correlation and simple linear regression in SPSS. Results revealed differentiated effects: financial resource mobilization significantly predicted preparedness & early warning (β = .57, p < .001), material resource mobilization best predicted mitigation & adaptive capacity (β = .60, p < .001), and human resource mobilization most strongly predicted response effectiveness & recovery (β = .63, p < .001). The models explained substantial variance (R² = .32 to .40). The study concludes that different resource types serve distinct functions across the DRR continuum and recommends integrated resource mobilization strategies that strengthen financial mechanisms for preparedness, material stockpiles for mitigation, and human capacity for response and recovery.
