Is self-sufficiency the ideal goal for urban food policy?

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.

Why do we keep losing agricultural land to the city?

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.

The emergence of values-based food chains

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.

Untangling the web of food environment studies

Food environment

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.

The three pillars of urban food resilience

Urban food resilience

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.

Schools, universities, hospitals… cities’ new allies to change the food system

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.
