One of the primary demonstration spaces for Itaipu Binacional's socio-environmental actions is the Bela Vista Biological Refuge (RBV) in Foz do Iguaçu. Established in 1984, its initial purpose was to shelter wild animals rescued from the reservoir area—where land habitat was lost—and to serve as a nursery for forest seedlings used to create the Binational's approximately 34,000 hectares of protected areas.
To adapt the refuge's spaces to current needs and demands, including the use of zoo design strategies and ex-situ conservation actions, Itaipu Binacional organized a two-stage architectural competition open to architects from all over Brazil. Below is the winning proposal by RibasMarçal Arquitetura and Tempo Arquitetos.
