Yes, it's definitely sustainable, which I think is important. One of the things that happens is that community gardens, typically run by women, tend to turn into profit centres, because they sell the excess—what they don't consume—in the marketplace. That can be everything from milk to vegetables and fruits to wheat.
Most of the work we do is around creating these sustainable solutions and building them out through almost micro-loan/micro-finance types of programs whereby they can actually grow excess food and then sell or trade it for a profit.
