Zooming-in zooming-out: a novel method to scale up local innovations and sustainable technologies

Based on two case studies from Bangladesh and Benin, the role of video in scaling up sustainable rice technologies is assessed. Both process and outcomes of participatory research increased the effectiveness of educational videos. At the same time, during the production of the videos researchers and development workers learnt about local innovations and changed their attitude towards working with farmers. To increase impact, learning topics should have a regional relevance. Hence a novel method called zooming-in zooming-out is presented . It starts with a broad stakeholder consultation to define regional issues. Only then are communities approached to get a better feel about their ideas, their innovations and the words they use in relation to the chosen topic (zooming-in). Key learning needs are defined and videos are produced in close consultation with the end-users. Consequently, while showing the draft videos to more villages (zooming-out), more insights are gathered about the innovations and their socio-cultural context, and further adjustments made. Based on a few well-selected local innovations, and merged with scientific knowledge, these videos were able to explain underlying biological and physical principles. The more these principles resonated with what farmers already knew and did, the more video became useful as a stand-alone method. Facilitation increased adoption of sustainable technologies, but was not always a prerequisiste.
