Bioeconomies at a Watershed Scale

The IISD promotes a watershed-based bioeconomy approach that utilizes naturally occurring plant materials and agricultural by-products to create renewable energy and high-value bioproducts. This model aims to bundle tangible products with environmental co-benefits, such as nutrient recovery and carbon sequestration, to create viable business cases. The document highlights specific applications in Canada's Lake Winnipeg region using cattails and in China's Wuliangsuhai Lake using common reeds.

• IISD's bioeconomy approach focuses on a watershed scale to create synergies between natural systems and socioeconomic ones, utilizing plant materials that are either naturally occurring or by-products of existing activities.
• The watershed-based bioeconomy model identifies and bundles tangible end-products with overlooked environmental, social, and economic benefits, including water quality improvements, carbon and methane credits, habitat improvement, and flood and drought protection.
• In the Lake Winnipeg region of Canada, IISD researched the use of cattails (Typha spp.) to capture nitrogen and phosphorus from the watershed. These plants are used to produce bioenergy (pellets, cubes, biomethane, syngas, ethanol, biocoal), biochar, biocomposites, and fertilizers.
• At Wuliangsuhai Lake in Inner Mongolia, China, the common reed (Phragmites australis) supports a bioeconomy that provides 100,000 tonnes of harvested material annually, supporting 2,000 jobs and generating 32 million yuan (CAD$5 million) per year primarily through paper and insulation panel production.
• Harvesting reeds at Wuliangsuhai Lake removes 14 tonnes of phosphates and 362 tonnes of nitrogen from the watershed and lake annually, supporting other ecosystem services such as recreation and migratory bird habitats valued at 7 million yuan (CAD$1.2 million) in 2003.
