I was a Peace Corps Volunteer in Mali, West Africa from 2007-2009. One of my favorite memories is visiting a vast vegetable garden near the city of Gao. Each gardener had their own garden space, creating a patchwork of gardens as far as the eye could see.
In the vast sea of sand and mud-brick homes, the colors of the vegetable gardens seemed more vibrant than back home. In the Sahel, water quickly seeps into the sandy soil. To help water the gardens more efficiently, small earthen walls were built around each garden bed. This technique helps keep the water near the plants, and also creates really organized garden beds. Here are some photos from my time in Mali.
