PhD: Water, Sanitation and Hygiene in Challenging Environments
In 2015 it was estimated that almost a third of the global population lacked access to improved sanitation facilities with almost a billion-people having no access to any sanitation facilities resulting in open defecation . Additionally, around 10% of the global population lack access to an improved source of drinking water . Access to these essential services has been mandated by the Universal Declaration of Human rights for over 70 years  and yet thousands still suffer the adverse health effects .
The global Sustainable Development Goals (SDG’S) provides the framework with which to achieve universal access to Water, Sanitation and Hygiene (WaSH) services by 2030 . Whilst huge progress is being made, spurred on by support from philanthropy such as the Gates Foundation  the biggest gains are being seen in urban environments or where installing engineered infrastructure is relatively simple.
Not all people live in contexts where traditional WaSH engineering infrastructure and services are appropriate. These ‘challenging environments’ have difficult geographical and/or geological conditions which may include high groundwater, rocky ground, flood affected areas or even housing on lakes. In Cambodia it is estimated that around 27% of the population (over 4 million people) live in challenging environments . With so many people living in challenging environments and only 10 years remaining to achieve the SDG’s there is a pressing need to better understand how WaSH services can be implemented and adopted by communities living in challenging environments.
In this project, it is expected that the researcher will develop standards and guiding principles for the provision of WaSH services in challenging environments, focused on the Asia-Pacific region particularly Cambodia. Using a discovery based methodology including interviews, participatory observation and strengths mapping the researcher will investigate and overcome current barriers to WaSH services which may include technology, governance and funding.
The engineering NGO Engineers Without Borders Australia (EWB) has an established challenging environments program based in Cambodia and Vanuatu . This research project will directly support the work of EWB who will act as the industry partner. It is expected that extensive fieldwork will be conducted in Cambodia and or Vanuatu for extended periods of time supported by EWB in country.
