Local Materials
Build with what is already in the room. Resourcefulness is a design discipline.
Frugal invention treats the bill of materials as a creative constraint, not a budget line. What is abundant nearby? What is being discarded? What infrastructure, formal or informal, already moves goods, money, and information through this place?
Local materials include the physical (bamboo, scrap metal, recycled plastic, agricultural waste), the digital (SMS rails, USSD menus, mobile money, low-bandwidth web), and the institutional (cooperatives, churches, kiosks, savings groups). A solution that rides on existing rails is cheaper, faster, and more legitimate.
Jaipur Foot uses vulcanized rubber from local tire shops. ITC e-Choupal runs on village PCs and shared kiosks. M-KOPA piggybacks on M-Pesa. The pattern is consistent: the materials were already there. The innovation was the recombination.

- ◆What raw material is being thrown away within a kilometer of the problem?
- ◆What rails, payment, transport, communication, already exist here?
- ◆Could a repair be done by a local technician with a $10 toolkit?
