Art Safiental, a biennial outdoor exhibition of land and environmental art, returns to Grisons, Switzerland, to inspire “Learning from the Earth.” 15 artists including Ursula Biemann, Julius von Bismarck, !Mediengruppe Bitnik, and Dharmendra Prasad contribute works that are “both campaign, methodology, and intervention.” Bismarck’s Trees Without Borders (2022, image), for example, permanently transplants a native larch above the local tree line, anticipating the effects of a warming climate.
