Maybe this doesn't look like much, but this is a plot where farmers are doing their own experiment (Farmer Field School). This particular experiment happens to be about Conservation Agriculture, a type of tillage and soil management system where farmers try to disturb the soil surface as little as possible. Here you can see a plot where farmers have used a 'ripper' which basically cuts slices into the soil to allow moisture to be absorbed. Anyhow, the point is that farmers are trying several different conservation ag treatments on this same piece of land in order to figure out for themselves which one is best for their situation. Every week they meet and visit the plot, make observations and discuss/analyze what they've seen. This was really the purpose of the  visit to Tanzania this  week (like Burundi), not getting into various bad  situations with vehicles.
