An interesting paper (Fletcher et al., in press) which argues that neoliberal faith in REDD+ schemes for forest conservation, on the basis that they represent market-based initiatives, is misplaced, as it is not feasible for REDD+ payments to fully offset the short-term economic benefits of natural resource extraction that are foregone. There is increasing focus on extending REDD+ out to sea as Blue Carbon schemes for mangroves, saltmarshes and seagrass, for which MPAs are often vehicles.

Overfishing, climate change, habitat destruction, and pollution remain major threats to the world’s ocean. But amidst all that there is some seriously good ocean conservation news worth celebrating. So, to continue the tradition started last year with listing 14 Ocean Conservation Wins of 2014, here’s a rundown for 2015 that will hopefully fill you with #OceanOptimism. These wins represent the diligent efforts of organizations and individuals too numerous to list, so let’s just start with a blanket shoutout to all of #TeamOcean for a great year.

Local conservation efforts are important to restoring and protecting coral reefs. However, if we don’t halt climate change those efforts will not be enough to save them. That’s why marine biologists and ocean lovers have their eyes on the COP 21 climate negotiations in Paris this week.

Last year, I co-authored a New York Times op-ed entitled “We Can Save the Caribbean’s Coral Reefs.” The premise was that we must not use inaction on global emissions reductions as an excuse to postpone local conservation actions. Dr. Jeremy Jackson and I wrote, “We need to stop all forms of overfishing, establish large and effectively enforced marine protected areas, and impose strict regulations on coastal development and pollution, while at the same time working to reduce fossil fuel emissions driving climate change.”

Part 5: Ecological Thresholds can Inform Resource Management

The Ocean Tipping Points project is a collaboration of natural and social scientists, lawyers, environmental managers, and stakeholders working to understand what drives abrupt ecological shifts, and how they might be prevented or reversed. This is the fourth blog in a series highlighting the latest research and insights from our team of researchers.

Non-linear threshold responses are common in ecological systems, driven by both natural and human-induced pressures on ecosystems. However, Incorporating ecological thresholds into management can be a daunting task. In many ecosystems we have limited ability to predict if a threshold exists, when and how rapidly it will be crossed, and if positive feedback loops that entrain the new state will develop.

Ocean conservation is hard. You fight the challenges of “out of sight, out of mind,” of largely unregulated high seas, and of waters so vast people find it hard to believe humans could actually overfish it (or as the saying goes in Jamaica, “fish can’t done”).

The ocean is indeed in deep deep trouble due to overfishing, climate change, pollution, and habitat destruction, and good science is needed to turn that around. This science doesn’t need to be fancy, expensive, or complicated. Rather, it needs to be thoughtful, targeted, and inclusive.

Here are six lessons I’ve learned (mostly the hard way) during my first decade of studying and working in ocean science and conservation that I wish I’d known from the very beginning.

To be effective, marine conservation must be based on rigorous and targeted science. The large and growing threats to ocean ecosystems — overfishing, climate change, pollution, and habitat destruction — coupled with the limited scientific capacity of most small island states make science-based management not only an imperative, but also a challenge. Here’s one part of the solution: better global collaboration between local and foreign scientists.

Two and a half years ago, the Waitt Institute launched the Blue Halo Initiative, through which we partner with governments and communities as they envision, design, and implement sustainable ocean management for their waters. In the time since, we supported the Caribbean island of Barbuda in passing meaningful legislation that zones the island’s entire coastal waters and protects 33 percent of them in marine reserves. This year we began working with the islands of Montserrat and Curaçao.

Policy change, even at its most efficient, is often difficult and slow. This can be especially true for conservation policy, which often involves curtailing private sector business practices. On the flip side, the policymaking process can be sped up by clear public support. That’s why the recent consensus between the Caribbean fishing and SCUBA diving communities is so important – both groups understand that their coral reefs and fisheries are in serious trouble. 

Over the past 45 years, Caribbean coral cover has declined by more than half. Fish populations have plummeted due to overfishing. Fishermen are having a hard time making a living. Meanwhile, SCUBA tourism has increased dramatically. It’s evident to locals who derive their livelihoods from the sea that the ocean ecosystem on which they’ve traditionally relied is deteriorating rapidly.

Mesh plankton net, bucket, thermometer, pipette, and microscope.  Rowena Valderrama with The SEA Lab in Redondo Beach gathers equipment and prepares to train volunteers on how to collect and analyze plankton samples from the local harbor. They are on the hunt for specific species of algae that may be toxic and lead to harmful algal blooms (HABs). The SEA Lab is a program of the Los Angeles Conservation Corps and her volunteers are mostly underserved young adults. Once a week they become citizen scientists and contribute important data to the Community HABwatch Program.

There are scores of resources for helping coastal planners gauge potential climate change impacts to natural resources and communities (e.g. www.natureserve.org/climatetoolsguide). Resources for gauging the economic/financial aspects of climate change adaptation actions (as opposed to climate change impacts themselves) are much rarer. There are very few software tools that deal with the costs and benefits of different adaptation options, but the EBM Tools Network (www.ebmtools.org) has found one as well as a number of other great resources on this topic:
