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 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.

Rediscovering urban food trees

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.

The A to Z of urban food analysis

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.

The subtle equation of sustainable urban food logistics

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.

Unnoticed, yet happening: food foraging in the city

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.

What do we know exactly about urban agriculture’s environmental impacts?

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.
