Climate change is causing fishery problems, but we can solve them

By Eric Schwaab, Rod Fujita and Jacqui Vogel

Climate change is already transforming the distribution and abundance of fish stocks around the world. Warming temperatures, lower pH levels and many other factors are causing many fish species to shift to better habitats and others to shrink in abundance. This is problematic for the communities that rely on these stocks, especially when the shifts cross jurisdictional boundaries, such as those between fishery management zones or national exclusive economic zones, known as EEZs.

Climate-induced stock shifts are causing more overfishing, illegal, unregulated, and unreported fishing, discarding, higher fuel use, injustice and even armed conflict. Unless fishery management and fisheries become more adaptive and resilient to climate change, these problems will only worsen, but it’s not too late for solutions like flexible allocation systems, dynamic spatial management, ocean observing systems and international collaboration.

Blue carbon: A better tomorrow begins below

By: Kristin M. Kleisner and Jamie Collins

As we embark this year on the United Nations Ocean Decade, you may be hearing quite a bit about blue carbon. But what is it, and why is it so important for the future of our planet?  Well, the oceans play a critical role in trapping carbon, and they have absorbed about a third of all human-generated carbon emissions since the start of the Industrial Revolution. This is important because the carbon that human activity has released into the atmosphere acts as an accelerator of climate change.

When carbon is stored naturally in the various parts of ocean and coastal ecosystems — sequestering it, or taking it out of the atmosphere, where it could contribute to warming — we call it blue carbon. The blue carbon storage reservoir includes waters, sediments, and marine plants and animals. Unfortunately, loss of habitat, overfishing and other human impacts, including those from climate change, are reducing the ability of the oceans to trap carbon. That’s why we are exploring pathways to restore these benefits now and help to secure a better future for us all. You can learn more about blue carbon and some of the ways in which we may be able to restore key pathways using this interactive site. Read More »

Collaborative research sheds light on creating climate-resilient multispecies fisheries

Worldwide, there is considerable interest in developing fishery management options that balance social, economic and ecological goals for multispecies fisheries. Ideally, fisheries management should strive not only to produce good yields from single stocks, but also to avoid serial depletion and prevent adverse impacts of fishing on marine ecosystems — a difficult, but achievable task.

How will climate change affect the bigger fishes in the sea?

By Katie Westfall and Kristin Kleisner

Tunas, sharks, billfishes and swordfish are wide-ranging species that can respond rapidly to environmental changes. Many within this group are top predators and can move across ocean basins and between shallow and deep waters in response to oceanic conditions. For these reasons, some of these species may serve as “climate sentinels,” or animals that can offer important insights into how a changing climate is affecting ocean processes and marine life.

The Blue Economy: from principles to practice

In recent years, investment circles have been abuzz with a bright new shiny object — the “Blue Economy.” Pick an impact investor, development bank or conservation fund out of a hat, and chances are there is a mention of the Blue Economy somewhere on their website. (Although technically, the Blue Economy has existed ever since humans began engaging in maritime commerce, but that’s another story.) Read More »

New report outlines causes of ocean decline and proposal for recovery

A new report by an independent global organization lays out an eight-point plan to reverse ocean decline and advance recovery of the high seas.

The Global Ocean Commission (GOC), an independent organization of prominent leaders from around the globe formed to develop feasible solutions for key challenges facing the high seas, yesterday issued its final report, “From Decline to Recovery: A Rescue Package for the Global Ocean.” It outlines five drivers of ocean decline and an eight-part proposal to recover the high seas, an area of our oceans outside the jurisdiction of individual countries.

EDF applauds the commission for bringing high-level international attention to the important role oceans play in sustaining life on the planet, and we are pleased to see the optimism and solution-focus of the report.  The commission’s call to action must be heeded; recovery of the ocean is both possible and imperative to sustaining life on earth.
