iDE pioneered market-based approaches in the WASH sector that incorporate private businesses, NGOs, and government stakeholders. Since iDE Vietnam launched the world’s first market-based sanitation program in 2003, this model has been successfully replicated across iDE’s global portfolio and by other organizations.

Cambodia Sanitation

iDE Cambodia has been a leader in achieving market-based sanitation at scale, a watershed for design, a dedicated resource for research and testing, and an example of what can be achieved through the right combination of sales, marketing, and management.

Our WASH work began in northern Ghana in 2015 with an initial human-centered design deep dive aimed at understanding rural Ghanaians' hygiene and sanitation behaviors, needs, barriers, and aspirations across the three northern regions.
