In 2008, about 40 of the men cleared a refuse [garbage] site in the neighborhood of Kibera.
Later they brought in new soil to be able to begin organic vegetable cultivation on the 1.2 acres of land. A greenhouse was set up in 2010.

Currently, a dozen crates of tomatoes and other vegetables are produced daily and sold at reasonable prices. The farm is managed by Youth Reform, a local organization for young people. In the next five years, the group plans to help other communities to set up the same type of organic vegetable growing project. Bravo, Youth Reform, and all those participating in this laudable green program.

We wish you much success and many more abundant harvests in your wonderful sustainable endeavor.
