Lagrangian Analysis Of Seasonal And Interannual Trends In Estuarine Flow Composition And Path Between Juan De Fuca Strait And Strait Of Georgia And Puget Sound, Becca Beutel Apr 2022

Lagrangian Analysis Of Seasonal And Interannual Trends In Estuarine Flow Composition And Path Between Juan De Fuca Strait And Strait Of Georgia And Puget Sound, Becca Beutel

Salish Sea Ecosystem Conference

Flow within Juan de Fuca Strait (JDF) accounts for the majority of the water entering and leaving the Salish Sea. As such, the health of the Sea’s diverse basins is strongly impacted by the composition and flux of the water within this strait. Complex flow at the mouth of the JDF means that a catalogue of Pacific currents, with different physical and chemical characteristics, play a role in the inflow. Within the Salish Sea phenomena such as variable river discharge and wind driven upwelling within the basins adds to the variability of the makeup and path of the water leaving. …

Rights Of The Salish Sea: A Major Paradigm Shift And An Innovative Legal Framework, Dr. Robin Reid, M. Kai Sanburn, Elisabeth Robson, Anne Whirledge-Karp, Chom S. Greacen, Julienne Battalia, Terry Marshall

Salish Sea Ecosystem Conference

Across the world, local to national governments are experimenting with recognizing the rights of the non-human environment. This is called the ‘rights of nature’. Euro-American law treats nature as property to be used and managed by humans. Rights of nature recognizes the rights of the environment to grow, thrive and be healthy, independent of humans. Indigenous Peoples often take the lead in these initiatives, as in the Maori-led rights of Aotearoa/New Zealand’s Whanganui River and Ojibwe-led rights of manoomin (wild rice). In the transboundary Salish Sea, there are growing efforts to implement this innovative rights framework. One such effort is …

Incentivizing Green Infrastructure Equitably, Aaron Clark Apr 2022

Incentivizing Green Infrastructure Equitably, Aaron Clark

Salish Sea Ecosystem Conference

Incentive-based ecological programs have a checkered history. By providing incentives for voluntary environmental improvement, landowners and communities have the power to choose what changes they want (rather than having changes imposed on them), improvements can occur despite no regulatory requirements, and those changes tend to be enduring because landowner and community buy in leads to better stewardship. However, most incentive programs allocate resources inequitably, funneling public money to improvements in higher income, wealthy and predominantly white communities. But this need not be the case. In 2012 our partners at ECOSS asked community members from several underserved racial and cultural groups …
