The last few decades have witnessed substantial gains in access to sanitation, as nearly 2.4 billion people gained access to improved toilets and open defecation (OD) rates fell 12 percentage-points globally (from 21% to 9%) between 2000 and 2020. Despite this progress, many countries are off track to meet their sustainable development goal (SDG) 6.2 targets. To reach these targets by 2030, a concerted effort is needed to broaden, combine, and strengthen existing approaches throughout the sector.
One possible response to this is area-wide sanitation (AWS), a systems-based, outcome-driven framework to achieve equitable, universal access and use of safely managed sanitation and hygiene in a given administrative area, such as a district. The purpose of this desk review is to collate the definitions and frameworks developed for AWS and examine how AWS programming has been implemented in practice. The aim is to arrive at a common definition of AWS, identify its core components, and develop a high-level theory of change (ToC) for how these components are structured.
WASHPaLS #2 compiled these core components into a draft Theory of Change that connects them to the intended outcomes of AWS, though the largest gaps remain around the lack of documentation of area-wide programs in practice, including how these components are to be implemented, particularly in rural areas and under resource-constrained governments.
