Three urban agriculture projects deliver 9,504 vegetable packages or portions to 110 households and run on 183 volunteers. The MKBA by New Economy counts both the food and the activation value. Urban farming combines fresh produce with meaningful participation. Without a calculation, the social value of informal food initiatives stays invisible, while the cost of inaction keeps rising.
A social cost-benefit analysis values the network’s benefits against public spending and avoidable social costs. This is relevant for municipalities, city districts and organisations working on food security, poverty and public health.
