17pgs, There is a lack of data on resources used and food produced at urban farms. This hampers attempts to quantify the environmental impacts of urban agriculture or craft policies for sustainable food production in cities. To address this gap, we used a citizen science approach to collect data from 72 urban agriculture sites, representing three types of spaces (urban farms, collective gardens, individual gardens), in five countries (France, Germany, Poland, United Kingdom, and United States). We answered three key questions about urban agriculture with this unprecedented dataset: (1) What are its land, water, nutrient, and energy demands? (2) How productive is it relative to conventional agriculture and across types of farms? and (3) What are its contributions to local biodiversity? We found that participant farms used dozens of inputs, most of which were organic (e.g., manure for fertilizers). Farms required on average 71.6 L of irrigation water, 5.5 L of compost, and 0.53 m2 of land per kilogram of harvested food. Irrigation was lower in individual gardens and higher in sites using drip irrigation. While extremely variable, yields at well-managed urban farms can exceed those of conventional counterparts. Although farm type did not predict yield, our cluster analysis demonstrated that individually managed leisure gardens had lower yields than other farms and gardens. Farms in our sample contributed significantly to local biodiversity, with an average of 20 different crops per farm not including ornamental plants. Aside from clarifying important trends in resource use at urban farms using a robust and open dataset, this study also raises numerous questions about how crop selection and growing practices influence the environmental impacts of growing food in cities. We conclude with a research agenda to tackle these and other pressing questions on resource use at urban farms.

3 pages, The COVID 19 pandemic has demonstrated clearly that change can happen suddenly and dramatically, creating great uncertainty. Social distancing is the norm world-wide as we all work to ‘flatten the curve’. The economy is crashing, and despite stabilizing attempts, continues to stagger. The combination of a pandemic with economies in decline around the world is increasing food insecurity across the globe (UN-FAO 2020).
But in uncertainty, new possibilities arise and new pathways open. Change creates the conditions for transformation. We now have an opportunity—perhaps a once-in-a-lifetime opportunity—to learn from past weaknesses and create food systems that are more healthy, sustainable, equitable and resilient.
Thinking ahead to post-COVID 19 food systems, it is important to ask, what are we learning about our level of preparedness? And what next steps are suggested by food system weaknesses at local, regional and global scales in the context of the international pandemic?
Lessons are already emerging from this crisis—and from the multiple innovative responses to it—about how to retool food systems toward sustainability and resilience. For example, numerous food providers and retailers have moved online (Open Food Network) and social enterprises are delivering fresh local food and backyard growing kits to vulnerable population groups.
13 pages, Green political theorists often highlight local food systems as an exemplar of ecological citizenship. Nevertheless, the topic has received scant systematic and critical treatment within green political theory. Although local food initiatives generally tend to be environmentally friendly, not all such initiatives lead to better environmental outcomes, nor can they be essentially characterized as citizenship practices that foster social justice. This article argues that a situated analysis is necessary to understand how a particular local food initiative promotes ecological citizenship. Through a qualitative study of community supported agriculture (CSA) participants in the greater Edmonton region of Canada, this article analyzes the civic virtues nurtured by this community and interrogates the extent to which their everyday practices resemble ecological citizenship. It concludes that discursive and structural limitations prevent the Edmonton CSA community from achieving meaningful diversity and addressing social justice concerns within its realm.
7 pages, Many current food systems are unsustainable because they cause significant resource depletion and unacceptable environmental impacts. This problem is so severe, it can be argued that the food eaten today is equivalent to a fossil resource. The transition to sustainable food systems will require many changes but of particular importance will be the harnessing of internet technology, in the form of an ‘Internet of Food’, which offers the chance to use global resources more efficiently, to stimulate rural livelihoods, to develop systems for resilience and to facilitate responsible governance by means of computation, communication, education and trade without limits of knowledge and access. A brief analysis of the evidence of resource depletion and environmental impact associated with food production and an outline of the limitations of tools like life cycle assessment, which are used to quantify the impact of food products, indicates that the ability to combine data across the whole system from farm to human will be required in order to design sustainable food systems. Developing an Internet of Food, as a precompetitive platform on which business models can be built, much like the internet as we currently know it, will require agreed vocabularies and ontologies to be able to reason and compute across the vast amounts of data that are becoming available. The ability to compute over large amounts of data will change the way the food system is analysed and understood and will permit a transition to sustainable food systems.
