Abstract

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.

美拉尼西亚太平洋地区服务不足的城市住区卫生系统多国调查

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 的主要具体目标。尽管为支持可持续发展目标 6 而开展的全球 "讲卫生运动 "监测工作取得了进展，但数据缺口仍然很大，尤其是在美拉尼西亚太平洋地区的城市非正规住区。本研究旨在加深对这些地区现有卫生系统、居民偏好和气候灾害风险的了解。对苏瓦（斐济）和维拉港（瓦努阿图）的 393 个家庭进行了入户调查。苏瓦（99%）和维拉港（70%）的卫生设施供水率很高，卫生设施的上层建筑也有明显改善。然而，在维拉港，没有石板的干粪坑仍然很多（15%）。对水基系统的偏好凸显了建立弹性卫生服务链的必要性，包括适当的粪便污泥管理，这在两个地方都存在问题。在瓦努阿图，关于气候灾害造成的损害的报告更为频繁，每三个受访者中就有一人报告其卫生服务受到影响。
