For academics, there are few things more satisfying than having a research paper you slaved over for months published in a top peer-reviewed scholarly journal. When a leading scientist then blogs enthusiastically about the article, telling the world how great it is, the feeling is even better. That's what happened this week for a group of IRIS researchers after they published an article in the prestigious journal Biological Conservation about whether to use "assisted migration" to help species adapt to a rapidly changing climate.
Assisted migration is the intentional translocation of species outside their historic ranges to mitigate biodiversity losses caused by climate change. While this idea has been around for decades, it has recently become the subject of fierce controversy in the academic literature.
The article was written by IRIS Senior Fellow and York geography instructor Dr. Nina Hewitt and an interdisciplinary team of IRIS-affiliated researchers from biology, environmental science, business, law and social science. It takes stock of the burgeoning academic literature on this topic and identifies possible avenues toward consensus on how to address what might otherwise become an intractable ethical and policy problem.
Joern Fischer of Leuphana Universität Lüneburg in Germany, a leading scientist in the field, wrote about the article yesterday in his "Ideas for Sustainability" blog. He congratulated the article for its thorough analysis of a very complex and polarized debate. It is polarized because many scientists see assisted migration as pitting two conservation goals against each other: the preservation of a single species from extinction, versus the protection of entire ecological communities against the risks posed by introduced species, which can have impacts similar to invasive alien species.
Fischer lauded the article for focusing on the nuances and complexities of the debate rather than accepting a polarized, black-and-white view. He especially liked a figure in the article that presents the arguments for and against assisted migration and their key inter-relationships in a one-page schematic.
Professor Fischer praised the article's effort to provide a conceptual framework within which scientists and policy makers can find common ground:
"The authors state that the debate is complex, and rather than proposing a simple solution, they try to provide a framework which can help to reach case-specific solutions. Hooray …! I wish more scientists did this. ... Hewitt et al. have done a great job of giving an authoritative overview of many relevant arguments. I highly recommend their paper!"
This endorsement from one of the protagonists in the assisted migration debate is a great vindication for the hard work that went into the study, and it suggests that the article will have a constructive impact both on the scientific debate and on conservation policies and practices on the ground. Achievements like this article really help to advance IRIS's mission as a national and international leader in practical, collaborative and interdisciplinary research that influences policy and decision makers on a variety of sustainability issues.
There is one irony in this story. The research was funded by the Canadian Foundation for Climate and Atmospheric Sciences, one of the victims of the Canadian federal government's recent massive cuts to scientific and environmental programs. These cuts are one of many sad indications of this government's unfortunate head-in-the-sand attitude toward climate change and other ecological challenges. CFCAS pleaded with the government, to no avail, to reconsider the cuts and devote adequate funding to weather and climate research.
