American Indian and Alaska Native tribes are uniquely affected by climate change. Indigenous peoples have depended on a wide variety of native fungi, plant and animal species for food, medicine, ceremonies, community and economic health for countless generations. Climate change stands to impact the species and ecosystems that constitute tribal traditional foods that are vital to tribal culture, economy and traditional ways of life. This paper examines the impacts of climate change on tribal traditional foods by providing cultural context for the importance of traditional foods to tribal culture, recognizing that tribal access to traditional food resources is strongly influenced by the legal and regulatory relationship with the federal government, and examining the multi-faceted relationship that tribes have with places, ecological processes and species. Tribal participation in local, regional and national climate change adaption strategies, with a focus on food-based resources, can inform and strengthen the ability of both tribes and other governmental resource managers to address and adapt to climate change impacts.

In the last two centuries, the reallocation of labor out of agriculture has been a dominant feature of structural change and economic growth in the United States. This paper uses an accounting framework founded in economic theory to decompose this reallocation into three components: a demand-side effect due to the low income elasticity of demand for agricultural goods (Engel effect), and two supply-side effects, one due to differential sectoral productivity growth rates (Baumol effect), and the other to differential capital deepening. The results show that the Engel effect accounts for almost all labor reallocation until the 1950s, after which the Baumol effect becomes a key determinant. Our framework provides a unified account of long-run structural change, and demonstrates that historical interpretations and theoretical models that emphasize only one dimension of this process cannot properly account for the dramatic history of labor reallocation in the United States.
