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. We currently work in 15 countries in Africa, South Asia and Latin
America.
