That's the conclusion of more than 50 researchers at Dartmouth and elsewhere in a special issue of the journal Climatic Change. It is the first time a peer-reviewed journal has focused exclusively on climate change's impacts on U.S. tribes and how they are responding to the changing environments. Dartmouth also will host an Indigenous Peoples Climate Change Working Group meeting Nov. 4- 5.
...Dartmouth assistant professors Nicholas Reo and Angela Parker, whose article is titled "Re-thinking colonialism to prepare for the impacts of rapid environmental change," said New England settlers created a cascade of environmental and human changes that spread across North America, including human diseases, invasive species, deforestation and overharvest.
The researchers identified social and ecological tipping points and feedback loops that amplify and mitigate environmental change. For example, prior to the arrival of Europeans, old growth deciduous forests were rich with animal and plant resources and covered more than 80 percent of New England. Native peoples helped to sustain this bountiful biodiversity for centuries through their land practices.
"But when indigenous communities were decimated by disease and eventually alienated from their known environments, land tenure innovations based on deep, local ecological knowledge, disappeared," the researchers say. "Colonists, and their extractive systems aimed at key animal and plant species, became the new shapers of cultural landscapes. Rapid ecological degradation subsequently ensued, and New Englanders created a difficult project of stewarding a far less resilient landscape without help from indigenous land managers who would have known best how to enact ecological restoration measures."....
