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.
Values-based food chains are a collective strategy that enable producers to realise the benefits of good stewardship otherwise not independently possible when competing in industrial food markets. A special issue in The International Journal of Sociology of Agriculture and Food explores their development in Europe and North America.
Is there a link between food accessibility and people’s health? Publications about food environment have blossomed in the last 10 years. In a chapter from the second edition of Neighbourhoods and Health, researchers from Harvard Medical School review this scientific literature. Their work reflects the difficulty to capture such a phenomenon and highlight that access to healthy food is necessary but not sufficient to improve people’s diets.
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.
Processing facilities are a missing link between local food and new markets, however, they face a double challenge: that of matching local production, high fixed operating costs and demand for local products. When thinking about opening new processing facilities for local food, it is necessary to carry out a full value chain assessment first.
Institutions such as hospitals, schools, universities, corporate cafeterias, or even prisons, are other big players in the food system. How can a shift in their practices help a transition to a more sustainable future? And what can cities do to foster their initiatives? A recent book called Institutions as Conscious Food Consumers presents an overview of action in Northern America.
New York is one of the pioneering cities for urban food policies. However, to date, there had been no systematic effort to look at the full picture of what these policies had achieved. This is done in a research report from CUNY Urban Food Policy Institute.
In a recent article in Sustainability, a group of researchers from New Zealand, Denmark and France discusses the advantages and limits of two main categories of food sustainability assessments: indicators-based and value-based. They provide valuable insights for any city willing to track progress of its food policy.
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.
