2020Paul Sherfey · Budkavlen · Global
This study explores human-animal relationships, particularly with insects, in collective gardens through observation and digital research. It demonstrates that in collective gardens, cultivating community is as important as cultivating organic produce, and this community includes not only humans but also animal species like insects. The article analyzes why gardeners show interest in building hotels and cafes, sowing meadows, and arranging festivals for insects, especially bees, and contrasts discourses about bees with the lack of similar discourse about wasps, considering how different cultural heritages affect the value placed on species.
