Dr Tim Jardine - Canada’s freshwater deltas as complex and vulnerable social-ecological systems.
In north-western Canada, glacial retreat left behind large lakes that led to the development of three massive freshwater deltas (Peace-Athabasca, Slave and Saskatchewan). The productivity of these delta floodplains drew both wildlife and humans, leading to strong cultural connections to the landscape and economic opportunities through the fur trade, fisheries and guiding. But throughout the 20th century, upstream water resource development coupled with oil and gas exploration has altered the quantity and quality of water entering the deltas, affecting plant and animal populations, livelihoods, health and social relations. In this presentation, I will offer an overview of the challenges facing these deltas and how a transdisciplinary approach has shed light on problems and potential solutions for these special places.
