Abstract

Disaster vulnerability is not just a condition but a consequence of the interactions of natural and social factors. From this viewpoint, it is imperative to consider both natural and social factors when planning effective disaster risk reduction strategies. This study sought to determine factors that predict disaster vulnerability. Specifically, this research determined the associations between several socio-ecological dimensions (e.g., environmental, social, and economic profile), coping capacity, disaster preparedness, and disaster vulnerability of selected households in Dumaguete city. Using snowball sampling, a descriptive correlational design was used to collect data from self-report surveys of non-probable samples of 150 households from different disaster-prone barangays. Frequency count, weighted mean, and standard deviation were used to describe the data, and a multiple linear regression analysis was done to test the study's hypotheses. Findings show that the respondents manifested moderate levels of coping capacity and disaster preparedness while having high levels of disaster vulnerability. The study revealed that disaster preparedness and coping capacity were negatively correlated to disaster vulnerability. Aside from coping capacity and disaster preparedness, environmental, social, and economic profiles were also noted to predict disaster vulnerability significantly. Environmental profile was the most vital determinant of the participants’ perceived disaster vulnerability. To better prepare for disasters, it is suggested that city disaster risk reduction strategies focus on helping vulnerable barangays develop better adaptive capacities and manage environmental hazards. This could include providing training on essential hazard management and creating income-generating opportunities to offset the adverse effects of disasters.

揭开灾害脆弱性的秘密:菲律宾杜马盖特市的多维分析
灾害脆弱性不仅是一种条件,也是自然和社会因素相互作用的结果。因此,在规划有效的减少灾害风险战略时,必须同时考虑自然和社会因素。本研究试图确定预测灾害脆弱性的因素。具体地说,本研究确定了杜马盖特市选定家庭的几个社会生态维度(如环境、社会和经济概况)、应对能力、备灾能力和灾害脆弱性之间的关联。该研究采用滚雪球式抽样方法,通过对来自不同易受灾害影响地区的 150 个家庭的非可能样本进行自我报告调查来收集数据。采用频率计数、加权平均值和标准差来描述数据,并进行多元线性回归分析来检验研究假设。研究结果表明,受访者的应对能力和备灾能力处于中等水平,而灾害脆弱性处于较高水平。研究表明,备灾和应对能力与灾害脆弱性呈负相关。除了应对能力和备灾能力外,环境、社会和经济状况也对灾害脆弱性有显著的预测作用。环境状况是决定参与者感知到的灾害脆弱性的最重要因素。为了更好地备灾,建议城市减少灾害风险战略侧重于帮助弱势镇发展更好的适应能力和管理环境危害。这可以包括提供基本灾害管理培训和创造创收机会,以抵消灾害的不利影响。
