Seaweed to Slow Down Climate Change: Ready? Or Not?

By / Bio / Published: August 15, 2023

Seaweed is a hot solution for mitigating climate change. Can this carbon-absorbing powerhouse really help?

Seaweed is having a moment. I’ve been working on seaweed for 40 years, and I’ve never seen so many headlines about how seaweed can save the planet. 

I can understand why. The need to save the planet is more pressing than ever. We must now dramatically reduce greenhouse gas emissions and, at the same time, increase the planet’s capacity to remove carbon dioxide (CO2) from the atmosphere to prevent even more catastrophic impacts of global warming.

Carbon and the Deep Blue Sea: Why Recovering Fish Stocks Hold the Key to Sequestering Carbon at the Bottom of the Sea

By / Bio / Published: September 20, 2019

Important progress is underway around the world to emplace sustainability in wild ocean fisheries. The big surprise, however, is that getting fisheries right at the global scale may also make an unexpected and potentially very significant down payment on helping fight global warming.

We have known for some time that fixing fisheries management is the right answer for economic and ecosystem well-being under today’s conditions. That outcome is moving from the  theoretical to the realm of the possible. For example, the past 12 months have seen the profound transformation of fisheries framework laws in Japan and Cuba, and Belize is about to follow suit. Even China has joined the hunt, both for reforming its own domestic fisheries — the biggest in the world — and also in the way the country imagines “environmental civilization” and the future of the world ocean.

Cuba and the U.S. can only solve shared conservation challenges by working together

By / Published: September 17, 2019

Over the past few years, U.S. policy toward Cuba has been a series of unilateral actions that have had severe impacts on the Cuban economy and undermined its emergent private sector, without any apparent benefits to the U.S.

Diverse groups are pushing back against these restrictions, from the U.S. Chamber of Commerce to public interest groups, from churches to a growing bipartisan coalition in Congress. They recognize that engagement is still our best chance of resolving decades-long disputes and tackling shared challenges.

The administration’s approach has substantially decreased economic and cultural exchange and created a chilling effect in other areas. Nonetheless, not all doors to travel, dialogue or cooperation have closed, and it’s essential we work to keep them open. In particular, the ongoing collaboration between Cuban and U.S. scientists has been fruitful, with tangible benefits to the people of both countries. Read More »

How important is the role of science in managing U.S. fisheries?

By / Published: August 21, 2017

Environmental Defense Fund (EDF) is proud to sponsor a panel this week at the annual meeting of the American Fisheries Society (AFS) – the nation’s preeminent organization advancing fisheries science – that examines the role of science in federal fisheries management. Ten years ago, Congress gave science a stronger role in fisheries management. Today, overfishing has dropped significantly in U.S. waters and we have seen a number of fish stocks successfully rebuilt. Coincidence? Unlikely.

This week’s panel will examine what part the strong scientific provisions of the law have played in rebuilding fisheries, new scientific innovations needed to address remaining challenges, and whether any additional changes to the law could further strengthen management success. Read More »

How science and technology can help save sharks

Every year, Shark Week gives us a peek into the world of shark research and the amazing science and technology developing to study these captivating animals. This year, we were amazed by ultrasounds for pregnant hammerhead sharks and measuring a goblin shark’s bite. The latest science and technology can also help fishermen seeking other species to avoid sharks, protecting them from a significant source of injury and death while saving fishermen money.

Globally, shark bycatch represents one of the greatest threats – maybe the greatest threat, — to shark populations. Worldwide, sharks caught as bycatch can make up nearly half of the total reported catch, and that’s not counting the large amount of catch that goes unreported. Often, fishermen want to catch more valuable species like swordfish and tuna using pelagic longlines, one of the most prevalent fishing gears on the high seas, and hate accidentally catching sharks instead. So how can science and technology help solve this problem? Read More »

Healthy Fisheries Need Sound Science, Good Policy and Stable Markets

Any fishery functions as a series of complex interactions among an ecosystem, the political arena, the economy, cultural norms and traditions, and other systems. Understanding these interacting systems is critical for achieving EDF’s triple bottom line goals: more fish in the sea, more food on the plate, and more prosperous communities. EDF has been tackling this challenge by bringing together expertise spanning disciplinary boundaries, including biology and ecology, social sciences, policy analysis, and business planning.  Members of EDF’s Fishery Solutions Center recently spent two days in Boston meeting with partners from Yale University, the Massachusetts Institute of Technology (MIT) and the Natural Resources Defense Council (NRDC) to integrate research efforts in support of sustainable fisheries worldwide.

Participants reviewed the recent global macro-analysis of the biological, social and economic upside that can be realized by aligning incentives in fisheries through the application of well-designed fishing rights.  We then considered three parallel analyses that allow deeper understanding of how to best design scientific, policy and market systems that allow for the upside to be realized.
