Ecological Economics

A study by The University of Osaka and the National Institute for Environmental Studies aimed to understand how different rewards influence citizen contributions to biodiversity data. Using the Biome app, 830 users joined a one-week experiment offering either cash, donation-based, or no incentives for posting nature photos. Cash increased total posts, while donations encouraged sharing of rare species. The study reveals how tailoring incentives can improve both the quantity and quality of biodiversity data collected through citizen science.
