At Kadagaya, we are specifically interested in developing open-source appropriate technology (OSAT), where the designs and generated knowledge are freely available. AT is usually small-scale, decentralized, environmentally friendly, energy-efficient, and simplified to the point that it can be implemented with local resources and materials. In addition, AT describes a method for providing for human needs with the least impact on the planet’s finite resources, while being socially appropriate for the target region. AT is not a specific system or device, but a method for evaluating a technology and its social, economic, and environmental impact in a specific application.

AT has been applied to a wide range of fields. Some examples include: self-powered water pumps, solar lamps and streetlights, affordable greenhouses, mini wind turbines, passive solar building designs, and solar food driers. Some of the factors used to determine whether a particular technology is appropriate for the intended region and application include: the availability of local materials; level of required maintenance and available expertise; lifetime of the system; negative effects of the manufacture and use on any part of the biosphere; affordability; and open-source availability of designs.

Kadagaya is developing AT in the following fields, with the focus on rural applications in developing countries.

• Sustainable agriculture
• Clean water and sanitation
• Machines and tools
• Waste management and recycling
• Renewable energy
• Technical materials
• Telecommunications and IT
• Health and nutrition
• Automation
• Education
• Social interactions
