Currently MAPHSA covers ~3.5 million km² of endangered forests and savannas in Brazil and Colombia. Priority: under-documented, high-risk areas beyond protected zones. SW & S Amazon, Cerrado, Caribbean Colombia, Eastern Cordillera, Eastern Lowlands. #ArcadiaFund @upf.edu @sdrecercaupf.bsky.social

New research shows that conflict shaped how ancient Tairona communities organized themselves. During tense periods, settlements clustered in strategic locations, strengthening cooperation and defense. #ArcadiaFund #Archaeology #Tairona @upf.edu @sdrecercaupf.bsky.social doi.org/10.1080/0093...

MAPHSA is collaborating with the Colombian Institute of Anthropology and History (ICANH) and the National Institute of Historic and Artistic Heritage (IPHAN). #ArcadiaFund #Archaeology @upf.edu @sdrecercaupf.bsky.social @iphangovbr.bsky.social
