In Ethiopia, centuries of farming along with a changing climate have left the land dusty and barren. Drought alternates with heavy rains and flash floods, endangering crops and people. Yet by planting native species on surrounding mountainsides, experts and local villagers restored the water cycle in only five years.

These irrigate local farms, which brings stability to the lives of inhabitants.
