I am building a sand dam to help a Kenyan village for Excellent, Pioneers of Sand Dams because dryland regions are tough places to live.

On the expedition with Excellent Development, I will stay in a small Kenyan town, learn about people's daily life, their challenges and hopes. I will join them in building a sand dam and see for myself just how it’s done and what it means. It’s hard work, there's no doubt about it, but it will make a real difference for this rural community in Kenya.

The constant search for water in drylands means that people have no time to invest in things like agriculture and education. So they are trapped in a situation they have no power to improve.

For instance, collecting water steals hours from every child’s school day. Making water available close to school through a sand dam means children can spend more time learning!

That's why sand dams make such a difference. They are the world’s cheapest method of capturing rainwater and this ancient, but quite brilliant, technology can help provide a year-round supply of water that gives hope for generations to come.
