Many scientific studies have looked into cities’ food self-sufficiency potential. An article published in the Journal of Cleaner Production reviews this literature and shows that, on the one hand, that it is very difficult to compare such studies, and, on the other, that cities should focus on circular and sustainable practices rather than sufficiency.
Urbanisation raises very salient questions for food security and agriculture next to the cities. What are the main factors explaining urban sprawl, and what can we do about it? In a paper published in Land Use Policy, researchers from France-based think-tank IDDRI and research centre CIRED review all the factors discussed in scientific literature.
Food, energy and water resources are closely interwoven. But what does it concretely mean for a city’s food system? And how does understanding these relationships help plan a more resilient food system? Researchers from New York University have developed a framework that helps cities map, and act upon, the links between food, energy, and water.
Gentrification the urban phenomenon in which local people are priced out of their neighbourhood. In a policy brief published in 2018, Nevin Cohen, from CUNY Urban Food Policy Institute in New York, usefully reminds us that food policy can play a role in this process.
Our cities host a great number of fruit and nuts trees, with potentially interesting implications for food security. Somehow, however, they fell off the radar of both local authorities and urban food advocates. A good reason to keep investigating and to learn from the few cities that have rediscovered urban food trees.
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.
In their recent paper, Petr Jehlička, Petr Daněk, and Jan Vávra unpick the idea that home gardening, home-grown food, or food self-provisioning is only a coping strategy for those hit with hard times. This highlights the importance to understand what home growing means to people rather than expecting it to fit your expectations.
With a projected 2 billion people living in slum by 2030, what can city or national governments in the North do to help alleviate global urban food poverty? The key for city cooperation lies in giving time to people to help them find their own ways instead of imposing solutions upon them.
Why is it so difficult for farmers operating just outside the city of Chicago to sell to people living there? This was the question that led a team of researchers from the University of Wisconsin–Madison (United States) to explore urban food logistics.
Their work, published in a report entitled Regional Food Freight: Lessons from the Chicago Region, unveils the historical trends that led to the consolidation of long distance supply chains at the expense of shorter ones, and the limits of the current food freight system. It calls for a more careful integration of food diversity into urban logistics.
Who forages and why? A team of researchers across a variety of Baltimore-based organisations carried out an exhaustive survey to identify what, why, and, for the first time, how much people foraged in the city. This study puts this activity on the radar of urban planners and raises questions regarding the health and sustainability risks and benefits of foraging.
