Just over a quarter of people on the planet live in water stressed countries. And our increasing demands for water as well as climate change is putting even more pressure on this finite resource.
We take a look at how Indian farmers are growing crops with a device that stores rain underground. Plus how a test farm in the US uses a special clay liquid to grow vegetables in the desert. Finally we visit a project in Cyprus that could help coastal cities clean and reuse their wastewater in a more eco-friendly way.
