We are travelling down a paved road in western Niger, on our way to the village of Garbay Tombo, which is participating in a project being spearheaded by Caritas Niamey. The horizon is ocher, dotted with greenery. There are trees scattered here and there and shoots of millet struggling to emerge from the ground, hampered in their efforts by the absence of regular rainfall. On the side of the road, a herd of magnificently horned cattle are lumbering along slowly, laboriously, in the sweltering heat. They head to a muddy water hole where they can slake their thirst.
