Safe and enduring water, sanitation, and hygiene (WASH) for all is the key target of Sustainable Development Goal 6. Despite progress in global WASH monitoring to support SDG 6, significant data gaps persist, especially in urban informal settlements in the Melanesian Pacific Region. This study aimed to improve understanding of existing sanitation systems, residents’ preferences, and climate hazard exposure in these areas. Household surveys were conducted with 393 households in Suva (Fiji) and Port Vila (Vanuatu). Water availability for sanitation was high in Suva (99%) and Port Vila (70%), with noted improvements in sanitation superstructure. However, dry pits without slabs remain significant (15%) in Port Vila. The preference for water-based systems highlights the need for a resilient sanitation service chain, including adequate faecal sludge management, which was problematic in both locations. Reports of climate-driven hazard damage were more frequent in Vanuatu, with one in three respondents reporting impacts on their sanitation services.

人人享有安全持久的水、环境卫生和个人卫生 (WASH) 是可持续发展目标 6 的关键目标。尽管在支持可持续发展目标 6 的全球 WASH 监测方面取得了进展，但仍然存在重大数据差距，特别是在美拉尼西亚太平洋区域的城市非正规住区。这项研究旨在增进对这些地区现有卫生系统、居民偏好和气候危害暴露的了解。对苏瓦（斐济）和维拉港（瓦努阿图）的 393 个家庭进行了家庭调查。苏瓦 (99%) 和维拉港 (70%) 的卫生用水利用率很高，卫生设施上层建筑也得到显着改善。然而，在维拉港，没有板的干坑仍然很重要（15%）。对水基系统的偏好凸显了对弹性卫生服务链的需求，包括充分的粪便污泥管理，这在这两个地点都存在问题。瓦努阿图有关气候造成的灾害损害的报告更为频繁，三分之一的受访者报告其卫生服务受到影响。
