Different cooking stoves for different contexts

Indoor cooking on open fires kills four million people a year. It also creates 15% of the global carbon dioxide emissions and means people have to spend hours each day searching for fuel. So the hunt is on for a safer and more efficient cooking stove. Delft University of Technology’s new design methodology, Context Variation by Design (CVD), aims not only to speed up development of a better product but also to create more efficient variations of gasifier cooking stoves for different situations.

Jan-Carel Diehl is Assistant Professor for the Design for Sustainability Programme at the Faculty of Industrial Design Engineering at Delft University of Technology and one of the brains behind Context Variation by Design. “Different countries have different cooking habits; so different sorts of foods cooked in different ways for different lengths of time using different sorts of fuel. So what is needed is a basic design for a safe, efficient cooking stove that can be specifically adapted to local needs.”

Crucial to Context Variation by Design is that these design-variables are considered simultaneously. So right now, improved cook-stoves are being developed and tested in South Africa, Uganda and Vietnam all at the same time, speeding up the process of making culturally and socially appropriate adaptations to the basic design, providing solutions for more beneficiaries and at lower costs. “That’s CVD in action – designing with attention for different kinds of context simultaneously.”
