I take my hat off for the Save School project team, led by Rose Nibagwire, making what to me looks like the biggest compost heap ever. It is quite common practice for schools to keep a few cows, usually in a zero grazing set up to supplement incomes and the food for the children in the school.
When I visited there in February I chatted with members from a permaculture project who were encouraging more meat and dairy consumption especially with young people as there is a level of retarded development in the population due to shortage of protein in the diet. The African diet is very heavy on carbs and fruit and sometimes essential nutrients can be lacking, so I can see a great need for more food production within schools and hard wired into the curriculum.
