Zusammenfassung |
While there is a popular perception that Canada is a water-rich country, the
Saskatchewan River basin (SRB) in Western Canada exemplifies the multiple
threats to water security seen worldwide. It is Canada's major
food-producing region and home to globally significant natural resource
development. The SRB faces current water challenges stemming from (1) a
series of extreme events, including major flood and drought events since the
turn of the 21st century, (2) full allocation of existing water
resources in parts of the basin, (3) rapid population growth and economic
development, (4) increasing pollution, and (5) fragmented and overlapping
governance that includes the provinces of Alberta, Saskatchewan, and
Manitoba, various Federal and First Nations responsibilities, and
international boundaries. The interplay of these factors has increased
competition for water across economic sectors and among provinces, between
upstream and downstream users, between environmental flows and human needs,
and among people who hold different values about the meaning, ownership, and
use of water. These current challenges are set in a context of significant
environmental and societal change, including widespread land modification,
rapid urbanization, resource exploitation, climate warming, and deep
uncertainties about future water supplies. We use Sivapalan et al.'s (2012)
framework of socio-hydrology to argue that the SRB's water security
challenges are symptoms of dynamic and complex water systems approaching
critical thresholds and tipping points. To Sivapalan et al.'s (2012)
emphasis on water cycle dynamics, we add the need for governance mechanisms
to manage emergent systems and translational science to link science and
policy to the socio-hydrology agenda. |
