EDF Releases New Blog for All Our Expert Voices: Collecting stories, ideas and arguments from all of our experts in one place

EDFish is where EDF’s ocean experts share their thoughts on ocean conservation issues. We advocate and innovate for a healthier ocean and provide a unique perspective on how to restore and maintain sustainable fisheries. However, we know you may have a broad interest in environmental issues.

That’s why we wanted to share with you Environmental Defense Fund’s new flagship blog, EDF Voices. EDF Voices collects stories, ideas and arguments from all of our EDF expert voices in one place. Our thought leaders use this space to weigh in on all sorts of environmental issues, from stories about ocean conservation in Belize to reflections on a life impacted by a magnificent songbird, the Golden-Cheeked Warbler.

We hope you like what you read on our new EDF Voices blog and become a subscriber!

Climate Change is Changing Fisheries

Recently, the impacts of climate change on fisheries have been in the news.  The emphasis has been on the inability of scientists to explain how climate change is affecting fisheries or to fix the problems it seems to be causing.  These include shifting distribution and abundance patterns of commercially valuable fish stocks – shifts that may leave fishermen stranded with very restrictive catch limits, even when they have been doing everything possible to protect and restore their stocks.  These problems are being felt acutely in New England, where catch of some valuable stocks has been highly restricted to rebuild stocks depleted by overfishing – but they face even more restrictions as scientists find less fish in the water, possibly due to migrations induced by climate change.

A better scientific understanding of how climate change influences the distribution and abundance of fish is certainly needed, but that may be less important than the need for more flexible human institutions that can rapidly adjust to those changes. Read More »

Newsflash! Warming oceans=changes in fish populations and ecosystems

A number of scientific studies indicate that warming waters are affecting fish populations globally—and often in unpredictable ways. This finding is significant for fisheries management because as fish populations shift, whole ecosystems are changed. A recent study covering 40 years of data illuminates these changes in fish distributions and a Huffington Post article examines the research conducted to date and highlights the uncertain implications of this knowledge. The article extensively quotes our own scientist and Director of Spatial Initiatives, Jake Kritzer. Jake comments on the difficulty of making management predications without a complete understanding of how complex underwater ecosystems are shifting:

“It’s an immensely complicated situation. You have climate change overlaying everything, and it seems to be changing the way everything works, which means we have a lot of problems. It’s getting harder and harder to assess the stocks, to model them and understand their dynamics and predict what’s going to happen. Because those models are based on years and years of experience reading fish stocks and studying them, they have been tested over a long time and they rely on a certain set of assumptions and conditions that now seem to be rapidly changing. Tools that have been fairly well established and worked well in the past just don’t seem to be working as well anymore.”

Managing Our Nations Fisheries 3 Conference: Take away messages

America’s fishing laws are generally working well to rebuild fish stocks, but there is still work to be done to make sure that our sustainable fisheries are sustainable for fishermen. That was the takeaway message from the recent gathering of the nation’s top fisheries advisors, scientists, members of regional councils and the eNGO community who gathered in Washington DC for the “Managing Our Nations Fisheries 3” conference on May 7-9. The conference convened to discuss how concepts, policies, and practice of fishery sustainability can be advanced to make the system work better for fishermen and fishing communities. It provided a forum for information exchange and an opportunity to hear a wide range of perspectives on the sustainability of fish stocks and ecosystem, and the fishing communities that depend on them.

This conference is an important exercise because it gives the entire fishing community (managers, fishermen, NGOs, industry etc.) the opportunity to think broadly about what’s been happening on the water and apply it to big policy issues that need to be resolved, clarified or improved. Read More »

The Business of Marine Reserves: Achieving Financially Sustainable Ocean Conservation

Ocean conservationists have been arguing for a long time that marine reserves are a good investment, because they help sustain many ecosystem services, including fisheries and tourism.  Various studies have helped to quantify the value generated by marine reserves, but a new study puts it all together and presents a convincing value proposition for marine reserves.  Now all we need are investors who can appreciate that value proposition and make it work economically, and the right combination of rules and governance that will make these new kinds of markets – ecomarkets – viable.

The benefits of marine reserves often outweigh the costs of establishing and maintaining them. You would think that there would be great demand for them, but instead the pace of marine reserve establishment has been slow and conflict-ridden.  Why? Because many groups of people benefit from the status quo, and would suffer short-term economic harm from marine reserves.  Also, the benefits of marine reserves take several years to accrue, while the costs are immediate.  And while some of the benefits are fairly concrete and flow to discrete user groups – like lower fishing costs and higher fishery yields near the borders – others are less concrete (e.g., biodiversity and aesthetics) and flow to many user groups (e.g. tourists and people who like natural environments), including some (e.g., future generations) that don’t have much say in present day decisions.

So theoretically, marine reserves can pay for themselves and then some.  But right now, few people want to invest in them.  How do we change that? Read More »
