Eco-Visionaries presents contemporary positions in art and architecture seeking answers to current environmental problems that transcend mainstream notions of sustainability. This comprehensive volume is a companion to the collaborative 2018 exhibition endeavoured by four participating European museums; Museu de Arte, Arquitetura e Tecnologia, Lisbon, Portugal, Bildmuseet, Umea, Sweden, LABoral Centro de Arte y Creacion Industrial, Gijon, Spain and HEK. Each show maintains a different focus and curatorial approach and for each, artists investigate alternative visions regarding humankind’s place on earth through video and sound works, paintings, and installations. While the series of exhibitions presents the works of artists and architects who offer critical reflections on pressing contemporary issues, the book unites research, essays, as well as a survey of the artworks. Besides the historical antecedents of current ecological thinking in the fields of art and design, this catalogue also promotes current approaches that represent alternative visions for future uses of energy, resources, and the environment.
