A desk study – based on previous field work – was undertaken to compare the experiences and resutls of promoting the technology of Domestic Rainwater Harvesting (DRWH) in Thailand and Nepal.
DRWH comprises a set of technologies and products used to store and use rainwater for domestic purposes, including drinking. Whereas DRWH has been successfully implemented for single households in both countries, only in Thailand this practice reached massive scale and mainstream practice.
Using the tool of the Technology Application Framework (TAF) for a rapid assessment of the situation in these two countries, the following key factors were identified to have hindered scaling up in Nepal: user’s perceiptions and habits, affordability and profitability, and provider capacity.
The comparision at hand clearly demonstrates the key importance of contextual factors. Even though similar technologies were used in the two countries, the outcomes were very different. More research on enabling and hindering factors for diffusion of innovations is needed.
