This paper identifies spatial patterns of body mass index (BMI) and obesity in the Metropolitan District of Quito, Ecuador, by applying spatial autocorrelation. We identified BMI hotspots in western rural parishes, and hotspots of obesity in northern urban parishes . We then explored associations between distances to food outlets, physical activity and smoking (independent variables), and BMI and obesity (BMI > 30) (dependent variables) by applying global regressions (GR) and geographical weighted regressions (GWR). Smoking was found to be significantly negatively associated with BMI and obesity. Distance to supermarkets was found to be negatively associated with obesity.
Sustainability objectives of non-profit sharing economy activities: assessing achievement. A case study of the food-sharing project Mundraub
University of Salzburg, Österreich
The rapid advance of Information and Communication Technologies has triggered a boom in online sharing activities. Meanwhile, sharing economy activities cover many sectors including the food sector. Particularly, regarding food sharing the idea of sustainability, participation, social interaction, and change of behavior play a pivotal role. An example therefore is the Mundraub project which aims at enabling the general public to share information on wild and forgotten fruit and nut trees, berry shrubs, and herbaceous plants located in public space (i.e. urban environment in Germany) and, thus, have others harvest them. Even though the literature highlights many benefits related to the Mundraub project, the question is to what degree the existing potential is actually used. To answer this question data (e.g. mapped plants) accessed from the Mundraub database were analyzed. The results reveal several hotspots and clusters across Germany with a high number of mapped plants, but there are also many areas where only few data are available. To leverage the potential of the Mundraub project, measures related to project publicity, founding of local activity groups and attracting the interest of societal groups which have not been reached by the project so far can be seen as promising.
