“The land is just like a human being, it needs treatment,” said Mulugeta Beshada from the humanitarian agency Concern Worldwide in Ethiopia who commissioned this assignment in September 2008. “Our farmers rely on rainfall as a mainstay in agriculture. When there is no rain, there is no food production.

“The global food crisis contributes to the problem. As for climate change, here we are currently experiencing it directly: the recurrent drought, year in, year out, the landslides, caused by heavy rain. And our land is badly degraded because it has been farmed so intensively. Each year more nutrients are removed and the binding effect of the soil is gone.”
