How about partnering with Peace Corps Volunteers? They participate in really cool extension projects. As a PCV, I lived and worked with farmers in rural villages in Senegal. One popular project was the build of mud stoves - made from clay, sand, dried manure- for safer more resource efficient cooking. It may take thinking outside the box, especially for some of the parts, but rural folks are so resourceful. Now, I’m not saying this project is perfect for Senegal, considering the climate and all, but PCVs serve in countries all over the world!
