Abstract: With climate events increasing in frequency and severity, effects on human life, particularly those most vulnerable, are projected to increase in coming decades. Defined as climate vulnerability, risks from climate events can take many forms, including flood damage to basic infrastructure, like household toilets. In this study of households in rural Cambodia, we investigate how climate vulnerability correlates with toilet dysfunction and abandonment using two household surveys, a latrine sales database, two flood-extent maps, and a composite climate vulnerability index. Using multiple linear regression and measures of association, we show that together and individually, increasing climate vulnerability and poverty increased toilet abandonment. Toilet dysfunction occurred more frequently in flood-prone regions during the rainy season and increased with more household members. How living in flood-prone regions affected households’ perceptions, practices, and experiences with sanitation was also characterized in detail. The results highlight the need for more scientifically rigorous evidence to improve climate-resilient toilet designs that provide access to a functional toilet year-round. Beyond technology, household behavior towards and maintenance of sanitation infrastructure is a critical concern, as unsafe practices were found to be more common among climate vulnerable households. Resources from the private, non-profit and government sectors must be re-routed to improve access to affordable sanitation in climate vulnerable regions. The sector should also strive to improve access to safely managed sanitation in rural communities, particularly ones who are most affected by climate change, in order to prevent pollution of natural resources and further protect public health.
