Urban beekeeping has gained salience because of its significance in biodiversity conservation and community building. Despite this, beekeeping practices in urban areas have received negative perceptions from residents, which stem from public safety concerns. There is, therefore, a need to enhance and/or work on appropriate rules for maximizing the...
Article
This study examines how quality is defined, re-defined and dynamically formulated amongst stakeholders under political and global market pressures while registering geographical indications (GIs) for non-edible non-timber forestry products (NTFPs)—namely, Iwate Charcoal and Joboji Urushi—in Japan. To that end, Convention Theory is used as a framewo...
