Appropriate Technology

Appropriate technology is an ideological movement (and its manifestations) encompassing technological choice and application that is small-scale, decentralized, labor-intensive, energy-efficient, environmentally sound, and locally autonomous.[1] It was originally articulated as intermediate technology by the economist Dr. Ernst Friedrich "Fritz" Schumacher in his work Small is Beautiful. Both Schumacher and many modern-day proponents of appropriate technology also emphasize the technology as people-centered.[2]

Appropriate technology has been used to address issues in a wide range of fields. Well-known examples of appropriate technology applications include: bike- and hand-powered water pumps (and other self-powered equipment), the universal nut sheller, self-contained solar lamps and streetlights, and passive solar building designs. Today appropriate technology is often developed using open source principles, which have led to open-source appropriate technology (OSAT) and thus many of the plans of the technology can be freely found on the Internet.[3][4] OSAT has been proposed as a new model of enabling innovation for sustainable development.
