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.

Authors cited evidence of need to design tailor-made strategies for communicating with farmers about this subject.
11 pages., via online journal., Climate change impacts will affect grassland farming in various ways in the future. Communication and knowledge transfer are crucial to implement on-farm adaptation measures required to meet these challenges in a timely way. Therefore, we need to know how grassland farmers perceive climate change and which factors influence their attitude. We hypothesized that besides direct factors such as region, farm size, age and education, farmers’ socio-cultural background and their beliefs and attitudes are most important in their reaction to climate change. To investigate this, we conducted a survey with extensive on-farm interviews (n = 82) in four distinctive regions in the North German Plain on a gradient from sub-maritime to areas with sub-continental climate. We found that with a more continental climate and less rainfall and with increasing farm size, grassland farmers were more aware of the implications of climate change. In a second step, to categorize the influence of personal beliefs on decisions concerning farming, we applied the typology approach and distinguished four farming styles. Farmers in the four groups differed in terms of climate change awareness and adaptation preferences (P < 0.05). Yield Optimizers and Modernists were more open-minded to rational and economic facts and showed a significantly greater willingness to implement adaptation measures than Idealists and Traditionalists, who need to be addressed at a more emotional level. The results of this study may contribute to the development of better‐targeted adaptation policies that will serve specific groups of farmers more effectively.

19 pages, The adoption of digital technologies is expected to impact the social sustainability of agriculture, in particular in the case of small and mid-sized family farms in Western Europe. Goal of this research was to assess these impacts, however widely accepted impact assessment schemes of social sustainability are missing. Against this background, a qualitative, two-stage Delphi survey was conducted in order to identify relevant impact categories of the adoption of digital technologies in family-operated small-scale farms of South-West Germany. The participating experts stated, for example, that the adoption of digital technologies on the farm could mean that new business models can be based on the use of digital technologies. However, they also stated that digital technology could overburden farmers, which could hinder digitization in this sector as a whole. Data protection and data security were also issues ranked highly important by the participants in the Delphi Process.
