Mapping Change
Mapping Change is an initiative to document and map the biodiversity of the American Midwest before it is ravaged by climate change. The American Midwest contains three of the world’s largest terrestrial ecosystems, with broadleaf forests, coniferous forests, and the prairies, all of which are under threat from rising temperatures, changing precipitation patterns, and extreme weather patterns. Mapping Change was developed by researchers at the University of Minnesota to document the historical ranges of native species by using fellow nature enthusiasts to transcribe the original written annotations of physical specimens into a database. Location, species name, and the original appearance of the specimen were all recorded and after digitalization, native species could then be mapped and modelled. To ensure accuracy, each specimen is reviewed by five citizen scientists and reviewed by a member of Mapping Change before it is added to the final database. The Bell Museum has curated a collection of over four million specimens collected over a 125 year period. Some of their samples were collected even before extensive European colonization and the subsequent habitat loss and fragmentation, so their collection and the database is quite possibly the most extensive collection of the three Midwest ecosystems available. So far, almost 5,000 volunteers have participated and have annotated over 17,000 species since the initiative started in 2009.

Air Pollution Robot
The dangers of air pollution to human health are well documented, though the traditional methodology of collecting and reporting on sample lags behind the need to keep abreast and regulate air pollution in a meaningful amount of time. The use of drones and robots have been identified by researchers as resources that can be tweaked […]

Telematic Rivers
Erica Kermani’s artwork seeks to answer a central question: if rivers were seeing an equal, living entity, would humans take issues like climate change threatening them more seriously? In his year-long art exhibition in 2017, Kermani, in collaboration with Diana Salcedo & Jeana Chesnik, created a new forum of interaction between humans and rivers to […]

Co-occupied Boundaries
Art is easily found in nature but rarely is what considered art today inherently natural. The concept of co-occupied mediums that serve to be both functional for nature and aesthetically pleasing to people is being actively explored by Asya Ilgun and Phil Ayres, from the CITAstudio at The Royal Danish Academy of Fine Arts. In […]
