Anthropological contributions to historical ecology: 50 questions, infinite prospects.

This paper presents the results of a consensus-driven process identifying 50 priority research questions for historical ecology obtained through crowdsourcing, literature reviews, and in-person workshopping. A deliberative approach was designed to maximize discussion and debate with defined outcomes. Two in-person workshops (in Sweden and Canada) over the course of two years and online discussions were peer facilitated to define specific key questions for historical ecology from anthropological and archaeological perspectives.

Planetary stewardship in an urbanizing world: beyond city limits.

Cities are rapidly increasing in importance as a major factor shaping the Earth system, and therefore, must take corresponding responsibility. With currently over half the world's population, cities are supported by resources originating from primarily rural regions often located around the world far distant from the urban loci of use. The sustainability of a city can no longer be considered in isolation from the sustainability of human and natural resources it uses from proximal or distant regions, or the combined resource use and impacts of cities globally.

Analyzing Historic Ecotonal Shifts.

Complex chains of mutual causation in human-environment relations may be analyzed by tracing past human interaction with the environment at the global, regional, and local scales. Historical analogues can be effectively employed to model the range of potential climate anywhere in the world. Their advantages include the use of actual regional airmass, hydrology, pedology, topography, and species distributional data, in addition to archaeology, documents, and ethnography.
