Waste management has become a serious challenge in urban areas of developing countries. However, managing municipal solid waste generated is the most costly urban service and needs community engagement in management of municipal solid wastes. Therefore, this study determined willingness to join and pay for improving solid waste management services and associated factors among households of Gedeo zone, Southern Ethiopia.
We performed a community-based cross-sectional study design to assess willingness to join and pay for improved solid waste management and its predictors among residents in Gedeo zone, Southern Ethiopia. Multivariate logistic regression analysis was computed to identify the factors associated with willingness to join and pay for improved solid waste management services. An adjusted odds ratio (AOR) with a 95% confidence interval (CI) was used to report an association, and a < 0.05 was used to declare a statistically significant association.
Of 552 study participants, 91.5% (95% CI: 89.2, 93.8) were willing to join and 86.3% (95% CI: 83.3, 89.4) of them were willing to pay for improving solid waste management services. Having a large family size, higher educational status, positive attitude, and good knowledge of waste management services, access to waste management services, and amount of waste generated per week were positively associated with willingness to support improved solid waste management services. In addition, we found that respondents with high educational status, monthly income, who had good knowledge of waste management, access to waste management services, and the amount of waste generated per week were significant predictors of willingness to pay for improved solid waste management.
This study found that a significant number of the respondents were willing to support and pay for improved solid waste management services. A higher probability of willingness to support and pay for solid waste management services among residents who had access to waste management services and good knowledge of solid waste management was observed. Therefore, wide-range awareness creation through mini media should be used to address poor knowledge. In addition, establishing more temporary waste collection sites in every corner of cities is needed to encourage households to support and pay for improved solid waste management services.
废物管理已成为发展中国家城市面临的严重挑战。然而，管理产生的城市固体废物是最昂贵的城市服务，需要社区参与城市固体废物管理。因此，本研究旨在确定埃塞俄比亚南部 Gedeo 地区家庭参与和支付改善固体废物管理服务的意愿及其相关因素。
我们进行了一项基于社区的横断面研究设计，以评估 Gedeo 地区居民参与和支付改善固体废物管理的意愿及其预测因素。采用多变量逻辑回归分析来确定与参与和支付改善固体废物管理服务意愿相关的因素。使用调整后的优势比（AOR）和 95%置信区间（CI）报告关联，使用 < 0.05 表示具有统计学意义的关联。
在 552 名研究参与者中，91.5%（95%CI：89.2，93.8）表示愿意参与，86.3%（95%CI：83.3，89.4）表示愿意支付改善固体废物管理服务的费用。家庭规模大、教育程度高、态度积极、对废物管理服务有较好的了解、能够获得废物管理服务以及每周产生的废物量与支持改善固体废物管理服务的意愿呈正相关。此外，我们发现，教育程度高、月收入高、对废物管理有较好了解、能够获得废物管理服务以及每周产生的废物量多的受访者，更愿意支持和支付改善固体废物管理服务。
本研究发现，相当一部分受访者愿意支持和支付改善固体废物管理服务。能够获得废物管理服务和对固体废物管理有较好了解的居民，更有可能支持和支付固体废物管理服务。因此，应该通过小型媒体进行广泛的宣传教育，以解决知识匮乏的问题。此外，需要在城市的各个角落建立更多的临时废物收集点，以鼓励家庭支持和支付改善固体废物管理服务。
