What can city networks achieve? The experience of climate change networks provides useful insights for food ones.
FAO and RUAF have published a very comprehensive Toolkit called “Assessing and planning sustainable city region food systems”. This is the result of a 3 years journey with 7 cities to develop a methodology to analyse urban city food systems that any city around the world can apply.
A team of researchers from the Technical University of Denmark and the Massachusetts Institute of Technology reviewed existing scientific evidence on the main forms of urban agriculture in northern climates. They found that given the great diversity of urban agriculture, scientific evidence about its environmental benefits remains patchy. It does, however, reveal that the method used to cultivate plants, the product and the location are the three components of the equation cities should take into account to develop environmentally sound urban agriculture policies.
Is local better than global? A European research project explored the question. The conclusion of the project is that, well, nothing is clear-cut. And cities should rather focus on bringing anyone – local and global food chains actors – on the path to sustainability.
What if households started growing half of the vegetables they need in their home gardens? What impacts would it have on climate change?
