Environmental and socio-economic effects assessment ensures that the effects of development activities are considered before they happen and that significant adverse effects will be mitigated. Dr. Amelie Janin, NSERC Industrial Research Chair in Mine Life Cycle at Yukon College taught this course over the Winter 2017. Through discussions with a series of guest speakers and with the instructor, the students were tasked to reflect on the environmental assessment process in Yukon and to write short essays. The essays have been compiled under one document.
