World Toilet Day 2025: Field Insights from Vanuatu’s WASH Supply and Demand Study
Author: Dr Mark Love, Research Fellow (IWC)
This World Toilet Day, it’s worth remembering that for many Pacific Island families, sanitation is not just about comfort – it is about children’s health, learning, and future potential.
Over the past three decades, Vanuatu has made some real progress: Joint Monitoring Programme (JMP) data show improved sanitation coverage rising from around 28% in 1989/1998 to over 80% from 2006 onwards, peaking at nearly 89% in 2016 (WHO/UNICEF, 2021). The latest Vanuatu Multiple Indicator Cluster Survey (MICS 2023) reports that 63% of rural households and 90% of urban households now use improved sanitation facilities (Vanuatu Bureau of Statistics [VBoS], 2024). Yet rural areas still rely heavily on basic pits, with unimproved options such as open pits and pour/flush to open drains remaining common, and open defecation persisting amongst nearly 5% of rural households (VBoS, 2024). Regionally, this mirrors wider Pacific trends, where urban access is generally higher than rural, with both lagging behind global averages for safely managed services (UNICEF EAPRO, 2024).
The consequences are stark. An estimated 29% of children under five in Vanuatu are stunted, with higher rates in rural areas (VBoS, 2024, p. 184). UNICEF’s 2024 Situation Analysis identifies stunting as a major development challenge, strongly linked to inadequate sanitation and poor water quality (UNICEF Pacific Islands, 2024). The pathway is increasingly well understood – environmental enteric dysfunction (EED), caused by continual ingestion of faecal pathogens, damages intestinal villi, impairs nutrient absorption, and is now recognised as a key mechanism linking unsafe WASH environments to child stunting (Crane, Jones, & Berkley, 2015; Budge et al., 2019). In this context, sustained improvements to rural sanitation and hygiene are central to Vanuatu’s health and development agenda.
However, sustaining gains has proven far harder than building toilets. Stitt’s (2005) review of the UNICEF/Ministry of Health Rural Sanitation Program (1988–2001) in Tanna found that while latrine construction targets were often met, many facilities were soon underused, poorly maintained, and soon abandoned (cf. Lindstrom, 2018; Schoeffel, 1995). More than a decade later, Morrison’s (2016) evaluation of water and sanitation programs in Tanna told a similar story: access to “improved” sanitation almost doubled – from 21% at baseline to 43% at endline (Morrison, 2016, p. 72) – yet within 18 months nearly half of inspected latrines had damaged slabs or broken doors (Morrison, 2016, p. 74). Moreover, behavioural change lagged behind infrastructure gains, with some households continuing open defecation due to convenience, habit, or cultural preferences (Morrison, 2016, p. 76; cf. Lindstrom, 2018). Interviewees described new WASH systems as external projects – “belonging to World Vision” rather than the community (Morrison, 2016, p. 99) – weakening local ownership and long-term maintenance.
Against this backdrop, the International WaterCentre (IWC), Griffith University, is implementing a WASH Supply and Demand Study in Vanuatu for UNICEF, with a strong focus on sanitation and hygiene. The team also includes Associate Professor Robyn Roberts (Griffith Business School) and Cedric Paniel (Engineers Without Borders Australia). IWC’s Dr Mark Love recently completed 30 days of fieldwork in Vanuatu, interviewing hardware proprietors, plumbers, government and NGO representatives, and facilitating focus group discussions in five rural communities on Tanna, with further research planned in rainwater-dependent Emao Island early next year.
Early findings from Tanna reiterate that:
- Sanitation remains a low priority
- Awareness of ‘stunting’ is extremely low
- The ongoing ‘build-neglect-rebuild’ cycle – fuelled by externally driven ‘projects’ –is delimiting community resilience and motivation
- Where there is reliable water supply (and even sometimes when there isn’t) the clear preference is for pour-flush sanitation options over VIP toilets
- Where community governance and collective action is strong, there is interest in improving sanitation across the whole community (rather than simply being a household responsibility)
- Awareness and follow-up support and monitoring to communities is critical for sustained impact and uptake
- Strengthened Area Councils were consistently identified as the optimal body for supporting improved sanitation and hygiene practices
This World Toilet Day, the message from the Pacific is clear: better toilets – and better management – are fundamental to breaking the cycle of poor sanitation and hygiene. However, the findings from past evaluations and our recent fieldwork underscore that infrastructure alone is not enough; without long-term support, strong supply chains, technical quality control, and genuine community ownership, sanitation gains in Vanuatu will remain fragile.
