Working with the Fond du Lac Band of the Lake Superior Chippewa, the Great Lakes Indian Fish and Wildlife Commission, the 1854 Treaty Authority, the Minnesota Department of Health, and the US Environmental Protection Agency, Earth Economics studied the importance of wild rice (manoomin) to Ojibwe cultural identity, spiritual traditions, and food security. This 2018 study focused on the overall economic contribution of wild rice to the Minnesota economy, and what losses of wild rice habitat has meant throughout the region.
