Practical Action is a development charity with a difference.  We know the simplest ideas can have the most profound, life-changing effect on poor people across the world.  For over 40 years, we have been working closely with some of the world’s poorest people – using simple technology to fight poverty and transform their lives for the better.

One example of a technology is a life-preserving innovation called a zeer pot; a simple fridge that helps to stop people’s chances of survival in Sudan from rotting away.  Made from local materials consisting of earth, sticks, water and sand, the zeer pot is one earthenware pot set inside another, with a layer of wet sand in between.  As the moisture evaporates, it cools the inner pot, keeping up to 12kg of produce fresh for up to three weeks; produce that would have normally perished in a couple of days.

For many families in Sudan a zeer pot can mean the difference between potential starvation and having enough food to feed themselves.
