Agriculture involves humanity's most important flows of energy. Responsible for feeding the vast majority of the world's population, human-managed agro-ecosystems experienced dramatic changes during the transition from traditional organic practices in the 19th century to highly industrialized processes during the late 20th century. The Sustainable Farm Systems project uses social metabolism methodology to understand how changing energy inputs shaped the productivity of specific agro-ecosystems in the past. This energy returned on investment (EROI) analysis provides important insights for contemporary concerns about sustainable agriculture.

The Natural Resources & Environmental Studies Institute (NRESi) at UNBC hosts a weekly lecture series at the Prince George campus. Anyone from the university or wider community with interest in the topic area is welcome to attend. Presentations are also made available to remote participants through Livestream or Blackboard Elluminate. More information will be posted about the presentation as it becomes available.

Past NRESi colloquia and special lectures can be viewed on our video archive, available here.
