Watershed covers roughly 20 percent of Canada, including oil sands; The Mackenzie may discharge more water into the Arctic than the St. Lawrence into the Atlantic

The governance of Canada's massive Mackenzie River Basin holds enormous national but also global importance due to the watershed's impact on the Arctic Ocean, international migratory birds and climate stability, say experts convening a special forum on the topic.

"Relevant parties in western Canada have recognized the need for a multi-party transboundary agreement that will govern land and water management in the Mackenzie River watershed. Successful collaboration will effectively determine the management regime for a watershed covering 1.8 million square kilometers or about 20 percent of Canada an area roughly three times the size of France and include the country's vast oil sands," says University of California Prof. Henry Vaux, Chair of the Rosenberg Forum, which meets Sept. 5-7 at Vancouver's Simon Fraser University with the support of the Walter and Duncan Gordon Foundation.

The Forum's goals include identifying legal and scientific principles relevant to the processes leading ultimately to a coordinated basin-wide approach to management, as well as prioritizing knowledge gaps.

The Mackenzie is Canada's longest river -- about 1,800 km -- and pours a staggering 10.3 million liters (enough to fill four Olympic swimming pools) into the Arctic Ocean every second, along with 100 million tons of sediment per year. That's slightly more water than the St. Lawrence River discharges into the Atlantic, according to estimates.

The Mackenzie Basin includes three major lakes (Great Slave, Great Bear and Athabasca, which together contain almost 4,000 cubic km of water) and many major rivers, including the Peace, Athabasca, Liard, Hay, Peel, South Nahanni and Slave.

Complex challenges confront this immense territory rich in natural assets, which include intact forests, vital habitat for wildlife and for birds that migrate as far as South America, deep stores of trapped carbon, and vast deposits of oil, oil sands, natural gas and minerals.

A 2011 report published by the Gordon Foundation urges the federal government to work with jurisdictions in the basin to implement a world-class water monitoring program and support credible, independent water research.

Says Thomas S. Axworthy, President and CEO of the Toronto-based Gordon Foundation, "The starting point of good water policy is knowledge and the starting point of knowledge is to monitor on a regular basis the quality of water in the Mackenzie Basin for the health of the North, Canada and the world."

Through bi-lateral and multi-lateral discussions, Canada's three westernmost provinces British Columbia, Alberta and Saskatchewan its Yukon and Northwest Territories, and the federal government are seeking to set objectives for surface and groundwater quality and quantity, emergency notification requirements, information exchange protocols and dispute resolution processes.

"Anything less than a basin-wide program with strict water quality and quantity standards, backed by binding requirements for prior notification and consultation and dispute resolution, will squander an opportunity to finally give the Mackenzie Basin a governance regime that will protect it for future generations," adds J. Owen Saunders, adjunct law professor at the University of Calgary and former Executive Director of the Canadian Institute of Resources Law.

Says renowned Canadian water scientist James Bruce: "Development activity in British Columbia and Alberta is intensifying adverse impacts of climate change. Agreements must take into account the growing regional impacts of climate change and the need for an adaptive management strategy."

The refrigerator-like cooling effect of ice and annual snow cover in the northern Mackenzie basin plays a vital role in weather and climate patterns in Canada and throughout the northern hemisphere.

Rosenberg Forum panelist Prof. John Pomeroy of the University of Saskatchewan expects climate change to impact northern basin hydrology significantly by causing more precipitation in the form of rain and a shorter snow-cover period, reducing snow's beneficial insulating effect on permafrost. Those new conditions will also increase the prevalence of ice layers, which can increase spring runoff and streamflow but restrict grazing by caribou and muskox.

Expanding shrub cover in formerly open tundra is resulting in warmer air, soils and greater streamflow generation, he notes. The loss of spring snow cover and expansion of shrubs warm the northern air and cause changes in weather patterns and climate throughout the world.

Dr. Pomeroy notes that permafrost thaw in the southern Northwest Territories is causing the large-scale collapse of black spruce forests and increasing stream flow. Coincident with increased stream flow generation in the northern Mackenzie River Basin, climate warming is decreasing stream flow generation in the basin's south tributaries, due to declining mountain snowpack and increases in evaporation.

Trapped within the permafrost, meanwhile, are ancient stores of greenhouse gases, the release of which could transform the region from sink to a source of greenhouse gases.

When ice layers thaw, slumping of the land results in the discharge of sediments to rivers and allows perched ponds and lakes to drain. Tributary river courses and groundwater flows can alter, leaving spawning areas disrupted. Melting permafrost can also severely damage drainage facilities, roads, buildings, and pipelines.

The Mackenzie Delta -- where the river meets the Arctic Ocean -- is increasingly subject to storm surges from the Beaufort Sea and salt water intrusion due to three factors: reduced nearshore ice, sea levels rising at accelerated rates, and more frequent severe winter storms.

Ecosystems in this productive area will increasingly be affected, and buildings and infrastructure in low-lying areas will be flooded more frequently.

The Rosenberg Forum will also review studies that reveal the economic significance of the Basin, including one completed by researchers Mark Anielski and Sara Wilson in 2009 that estimated the 2005 market value of economic activities in the Mackenzie watershed at $41.9 billion.

At the time, the growing industrial footprint in the region covered about 25.6 million hectares, twice the combined area of Canada's maritime provinces New Brunswick, Nova Scotia and Prince Edward Island.

The researchers quoted a non-market value of the watershed (ecosystem goods and services provided by nature such as carbon storage, water filtration, water supply and 14 others) of almost $571 billion per year (2005), some 59% of which -- $339 billion -- was attributed to the storage and annual absorption of carbon by the basin's forests, peatlands, wetlands and tundra.

"If the environmental services of the basin were compromised, the loss would be very large," says Alberta-based water policy analyst Bob Sandford, who notes that climate change is occurring in the north at a rate three times that of the rest of Canada.

He and many scientific colleagues are expressing concern about persistent toxic compounds appearing in aquatic ecosystems of the Mackenzie River Basin, most derived from air pollution. Alberta's David Schindler and colleagues have shown that atmospheric emissions from oil sands developments are significant contributors to contamination of waters in the Mackenzie River Basin. These contaminants are transported by wind and deposited on snow, land and tree needles, eventually washing into rivers and lakes.

The Forum will consider recently announced Canadian government measures to monitor and mitigate oil sands-related pollution.

Objectives for the Rosenberg Forum:

To identify and summarize pertinent scientific principles and findings that should be acknowledged in processes leading to a Mackenzie River management agreement, as well as pertinent legal principles that may apply, and to address the following questions:

1. What is the state of scientific knowledge of the Mackenzie River Basin? What are the major scientific questions to be addressed to ensure that the waters and lands of the basin are managed in a way that protects their integrity? To what extent does scientific uncertainty need to be addressed and specifically acknowledged in any transboundary agreement? What does science tell us about the continental and global significance of the basin?

2. To what extent does indigenous knowledge supplement or reinforce typical western science or social science? To what extent does indigenous knowledge need to be acknowledged or incorporated in any agreement? Are there examples of transboundary agreements that rely upon indigenous knowledge?

3. Given prevailing levels of uncertainty, what should be the role of adaptive management in scoping and implementing any transboundary agreement? What are the positive and negative lessons learned from experience with adaptive management? Are there examples of transboundary agreements that rely on adaptive management?

4. Is it possible to revamp existing cooperative governance structures for the Mackenzie Basin so as to build upon rather than infringing upon the jurisdictions of the federal, provincial, territorial and indigenous governments? Are there examples where this has been successfully accomplished in a federal system? Are there examples of where it has been attempted but failed to work effectively?

5. Could an existing layer of government or a regional governmental entity be given regulatory authority related to the purely basin-level aspects of such overarching issues as climate change, cumulative environmental impacts, as well as transboundary indigenous treaties and governance agreements?

Wednesday, September 5th will be devoted to "fact finding." On that day, senior provincial and territorial officials as well as researchers working in the Mackenzie Basin have been invited to make presentations.

Thursday, September 6th and Friday, September 7th will be devoted to deliberations of the panel and the development of conclusions and recommendations.
