Accelerating progress on climate resilient urban sanitation: Three models of scale-up linking technological innovation and systems change

<p dir="ltr">Given the pace of climate change and its widespread disruption to sanitation services, awaiting passive diffusion of new technological innovations is insufficient. Models of scale-up or amplification articulate deliberate strategies that can be used by sanitation stakeholders to scale technological innovation. In this brief we introduce three models that can accelerate, amplify and scale-up technological innovation and systems change for climate-resilient urban sanitation. </p><p dir="ltr">By understanding these distinct but complementary models for scaling innovation, sanitation professionals can make more strategic decisions about the where to invest resources in the face of climate change. The models can inform how to move from technological innovation to wider systems change and evidence needed to support such pathways. Whether you fund technological innovations, develop research solutions, or shape policy environments, these models offer a structured way to guide and direct your efforts for greatest impact. </p>
