Death by a thousand cuts: salmon falling through the cracks in B.C.’s fragmented policy landscape



New research from Simon Fraser University (SFU) Biological Sciences researchers finds that Pacific salmon are facing escalating threats due to a lack of coordinated conservation policy and oversight.

New research from Simon Fraser University (SFU) Biological Sciences researchers finds that Pacific salmon are facing escalating threats due to a lack of coordinated conservation policy and oversight.

Their study, published this week in FACETS outlines how the existing suite of environmental regulations across multiple jurisdictions in British Columbia is failing to manage the cumulative impacts of industrial development and climate change on salmon and watersheds, and suggests opportunities for reform.

“There’s no single smoking gun for salmon,” says lead author Marta Ulaski, who notes that salmon face pressures from multiple different stressors, including forestry, mining, urban development, aquaculture and climate change. Each of these sectors is regulated separately without coordinated oversight.

“All these different industries have their own laws and regulations that are enabling harms that, even if incremental, are adding up,” adds coauthor and SFU biological sciences professor Jonathan Moore. “There is no single policy tracking the state of salmon watersheds that looks across industries and sets hard thresholds that clearly say enough is enough.”  

Policy reform needed

To address gaps in regulation the authors suggest a cumulative effects management cycle that includes collaborative on-the-ground monitoring, regional cumulative effects assessments, enforceable legal thresholds through spatial planning, regional governance, and climate-adapted policy frameworks.

“There are great tools out there that are bringing data together on the status of watersheds,” says Ulaski, “but these frameworks need to be given policy teeth so that they set enforceable thresholds.”

Underutilized tools such as Water Sustainability Plans and Modernized Land-use Planning can also play a role in reform. The authors point to collaboration between the Cowichan Tribes and the Province of B.C. on the Xwulqw’selu (Koksilah) watershed Water Sustainability Plan, and the Skeena Sustainability Assessment Forum as good examples of regional plans that integrate climate science and Indigenous knowledge into watershed management.

New challenges on the horizon

In addition to the situation outlined in their paper, Ulaski and Moore note that this is a critical moment as both the federal and provincial governments move to fast-track major infrastructure and energy projects considered to be in the national or provincial interest. 

“Without clear definitions of national or provincial interest and robust protections for ecosystems and Indigenous governance these legislative shifts risk exacerbating the cumulative harms this study warns against,” they say.

“We are asking too much of salmon and their ecosystems,” says Ulaski. “Our current piecemeal approach to industrial development and environmental regulation is not working. There is urgent need to adopt a more holistic approach to environmental regulations in B.C. to protect salmon and the people who rely on them.”

This study was the result of a collaborative project involving 14 experts in science and policy from institutions that included Simon Fraser University, University of British Columbia, Fisheries and Oceans Canada, West Coast Environmental Law, Central Coast Indigenous Resource Alliance and the POLIS Project of Ecological Governance at University of Victoria as part of the Watersheds Futures Initiative.

UC Davis study reveals why sharing data between tech rivals can be winning strategy



Specialist firms can ease competitive pressure from tech giants




University of California - Davis

 





In today’s data-driven economy, firms typically guard their data as a crown jewel of competitive advantage. But new UC Davis research suggests that, under certain conditions, the smartest move may be to share that data — even with rivals.

The study “The Strategic Value of Data Sharing in Interdependent Markets,” co-authored by UC Davis Graduate School of Management Distinguished Professor Hemant Bhargava, was published in June in the journal Management Science.

Their research provides a groundbreaking framework showing how smaller, specialized firms can protect their market position against Big Tech giants like Google and OpenAI by strategically opening their data vaults.

“Data sharing can look like surrender, but in fact it can be a powerful strategy,” said Bhargava. “It reduces pressure from generalist rivals by making them stakeholders in the specialist’s survival. At the same time, it offers policymakers new insights into how to encourage competition without stifling innovation.”

Bhargava and co-authors demonstrate why such data-sharing mandates might not only level the playing field, but also — paradoxically — strengthen smaller firms.

Their model shows that by granting access to their market data, specialist firms can turn a formidable rival into a “coopetitor.” Instead of competing aggressively, the larger generalist firm softens its approach because it now benefits from the specialist’s continued success.

Mobvoi partners with Google Cloud

The study highlights real-world examples such as smartwatch maker Mobvoi, which shares user data with Google Cloud. This unusual partnership helped Mobvoi improve product quality while reducing direct competitive conflict with Google’s own wearable devices.

Researchers also issue a warning, however: while firms may profit from data sharing, consumers don’t always benefit. Softer competition can result in higher prices and less innovation. For regulators, this underscores the need for a nuanced approach. Mandatory data sharing is not a one-size-fits-all solution, researchers said.

As competition in digital markets continues to heat up, this study provides a timely, rigorous lens for understanding when and why sharing data might just be the savviest competitive move of all, Bhargava said.

Co-authors of the study include Antoine Dubus, ETH Zurich, Department of Management, Technology and Economics; David Ronayne, European School of Management and Technology, 10178 Berlin, Germany; and Shiva Shekhar, Information Systems and Operations Management Department, Tilburg School of Economics and Management, Tilburg, Netherlands.

Educational attainment and intelligence, and to a smaller extent parental education and father’s occupational class, are associated with midlife socioeconomic status, according to a new study published September 10, 2025 in the open-access journal PLOS One by Erik Lykke Mortensen of University of Copenhagen, Denmark.

Socioeconomic status (SES)—a measure of individual differences in access to material and social resources—has long been linked with health, morbidity, and cognition. Previous studies have found paternal occupation, childhood intelligence, and educational attainment to be important predictors of SES later in life.

In the new study, researchers used data on 6,294 members of the Metropolit 1953 Danish Male Birth Cohort, which has followed Danish men over the course of many decades. Those included in the new analysis had participated in an intelligence assessment at age 12 and were still living in Denmark at age 50.

Educational attainment at age 30, and IQ at age 12, were mostly strongly correlated with midlife socioeconomic status, explaining more than half (53.5%) of SES variance. Young adult height, late childhood creativity and arithmetic test scores, parental education, and father’s occupational class also showed some predictive associations, improving the explained variance to 54.1%. These effects were mostly indirect and ultimately mediated through intelligence and education; children of well-educated parents, for instance, are more likely to pursue higher education.

The study is limited by its reliance on one generation of Danish men and the results may not be generalizable to other populations, the authors caution. However, they conclude that educational attainment and young adult intelligence are the most powerful predictors of midlife SES.

The authors add: “It is important that we were able to confirm the importance of family background and intelligence and to show that education was a particularly strong predictor of midlife socio-economic status in Denmark. However, it may be even more important that the results show that the influence of early life factors is underestimated unless both direct and indirect effects are analyzed.”

“In younger generations of Danes, education may be a somewhat weaker predictor, while individual characteristics such as intelligence and personality may have a stronger influence on socio-economic status attainment.”
