CAT TAIL BIOPLATFORM TECHNOLOGY

FLOATING A NEW IDEA
For water stewardship
FR_ RESUMÉ
UNE NOUVELLE IDEE
Les proliférations d'algues ont pris de
l'ampleur dans le lac Winnipeg, dont
le bassin hydrographique canalise le
ruissellement riche en éléments nutritifs.
Une nouvelle technologie prometteuse
permet non seulement de réduire
la charge de nutriments, mais aussi
de créer une bioéconomie des zones
humides. Shawn Stankewich discute du
potentiel des bioplateformes.

EN_
IN LAKE WINNIPEG, algal blooms have
been growing in size and frequency
for decades as the watershed funnels
nutrient-rich runoff into the world's 10th
largest freshwater lake. Monitoring and
observation technologies have increased
in sophistication and we now have a clearer
understanding of what is going wrong.
However, solutions are not so unequivocal.
THE END OF THE PIPE
In Manitoba, fresh water is abundant,
but not exclusively our own. Seventy per
cent of the 900 trillion litres of surface
water that flows through the province
originates in other jurisdictions. In fact,
the Lake Winnipeg watershed occupies
over 1,000,000 square kilometres and
encompasses parts of four Canadian
provinces and four American states. Lake
Winnipeg is at the end of the pipe and is,
therefore, affected by varied land use

practices and regulations in a multitude of
regions. Nonpoint sources of eutrophication
such as excess nutrients in runoff can be
difficult to control or coordinate. Because
cross-border water stewardship remains
a challenge, researchers are searching for
alternative ways to reduce the volume of
nutrients flowing into the lake.
THE PROMISE OF A BIOECONOMY
One very promising possibility is a new
technology that not only reduces nutrient
loading, but also turns the problem into an
opportunity. Researchers based at Winnipeg's
International Institute for Sustainable
Development (IISD) are asking an intriguing
question. What if there was a way to recapture
the nutrients, to create a wetland bioeconomy?
Phosphorus, the principal nutrient responsible
for eutrophication, is also a limited resource
which is often used in agricultural production.
After use on the fields, and the subsequent
potential runoff, it is "lost" in the watershed
and fuels the unsightly algal blooms found in
the lake.

IISD's Netley-Libau Nutrient-Bioenergy
Project provides concrete evidence of
the benefits of using wetland vegetation,
specifically cattails (Typha spp), to pull
nutrients from the system while providing
plant mass for biofuel. When burned, the ash
from this biofuel can be processed to extract
phosphorus for re-use in fertilizers, providing
potential to sell it back to the agricultural
industry. The pilot project also proves that
harvesting wetland biomass as an alternative
fuel source would offset carbon emissions,
generating potential for carbon credits
