Characterizing the dissemination process of household water treatment systems in less developed countries

摘要: Recently, household-level water treatment and safe storage systems (HWTS) have been developed and promoted as simple, local, user-friendly, low cost alternatives to conventional municipal-level drinking water systems. Yet, despite conclusive evidence of the health economic benefits HWTS, the implementation outcomes slow, reaching only approximately 5-10 million people. This study attempts to understand barriers drivers affecting HWTS implementation. A review existing literature on implementation found that research effort promote is rather fragmented, with a narrow focus either on technical, psychological, or marketing perspective. Also, application innovation diffusion theories has largely unexplored. To fill these gaps, it proposed a system dynamics modelling approach characterize complex diffusion process of HWTS can be valuable tool identify high impact, leverage strategies scale-up adoption and sustained use.
