Low-tech approaches for sustainability: key principles from the literature and practice.

Low-tech approaches have come to the fore in the last few years, mainly in opposition to the techno-optimistic model proposed to solve current and future environmental crises. However, low-tech thinking is multifaceted, making the concept potentially rich but also vague. This article develops a seven-principle framework to categorize low-tech concepts based on an abductive approach which included a literature review and interviews with low-tech actors. Principle occurrence was assessed among the authors and interviewees. The results demonstrate that the low-tech movement entails more than a shift to robust and less-consumptive technical artifacts. While resource efficiency and material reuse are important traits of low-tech approaches, technical appropriation is the most frequently cited key principle in the literature and by the actors. This delineation into several principles can help to differentiate low-tech from other sustainability concepts related to resource conservation such as frugal innovations and circular economy. We aim in this article to open a discussion about the ways low-tech proponents are seeking to introduce transformative development pathways to sustainability. [ABSTRACT FROM AUTHOR]
