What is frugal innovation, and why does it matter in a crisis?

Frugal innovation is the art of doing more with less: designing effective solutions using the fewest possible resources, and making them affordable, accessible and easy to maintain. It is less about big budgets and cutting-edge labs, and more about ingenuity - solving real problems with what is actually available.

The concept is often associated with resource-constrained settings, where necessity drives creativity. A water filter made from locally sourced materials, a charging light powered by a small solar panel, a shelter that can be assembled without specialist tools - these are frugal innovations. They strip a product back to what matters, prioritise repairability, and can be reproduced without a factory.

In a crisis, these qualities become vital. When supply chains break, budgets are stretched and infrastructure fails, the most sophisticated solution is useless if it can't be repaired, powered or understood locally. Frugal innovation flips the usual logic: instead of asking what the best-resourced solution looks like, it asks what works reliably under pressure, with limited means, in the hands of ordinary people.

Nowhere is this clearer than in Ukraine, where communities and makers have responded to war with extraordinary resourcefulness - adapting equipment, repurposing materials and building what they need under conditions no design brief could anticipate. This kind of citizen-led, frugal innovation under conflict is one of the reasons Ukraine's Kyiv National University of Technologies and Design (KNUTD) is a partner in OPEN RELIEF: there is real expertise here that the rest of Europe can learn from.

OPEN RELIEF treats frugal innovation as a core skill, not a fallback. Across Croatia, Greece and Ukraine, the project trains creatives, humanitarian workers and community members in frugal, repairable, open-source design - and applies those principles to eleven preparedness solutions built to be reproduced and maintained locally.

The lesson frugal innovation offers is a hopeful one. Resilience doesn't have to be expensive or imported. Often, the most durable solutions are the simplest ones  - designed with care, shared openly, and built to be fixed by the people who need them most.
