MAPPING CAPACITY, DEMAND AND PRESSURES FOR HYDROLOGICAL SERVICES IN CANADA
Human settlements in Canada are mostly located at the southern edge of the country, but the watersheds that provide Hydrological Services (HS) often span across large northern areas. In the lights of competing interests for undeveloped lands and climate change, it is imperative to identify critical watersheds for the provision of HS in Canada.
Ecosystem services are often conceptualized as two main components, namely capacity and demand. In river systems, the capacity and the demand for a service can be separated by long distances and, yet, be connected by river networks. So, to ensure the long-lasting quality of HS, it is necessary to consider and sustainably manage ecosystems upstream of the demand for these services. Using four HS, provision of water for municipalities, agriculture, industries and hydroelectricity, a map of critical watersheds in Canada was created using a hydrological approach. The demand for a service was redistributed on the land considering the runoff contribution. We used a cumulative approach to map out the hotspots and aimed to identify regions and river types potentially at risk. Identifying these key areas is beneficial for long-term and large-scale sustainable management of water resource.
