Managing for Resilience – Guadeloupe, 2011

Part of the 4th International Tropical Marine Ecosystems Management Symposium (ITMEMS), this learning exchange included 58 individuals. The Reef Resilience Network participated as conference leaders and dedicated a day of the conference to resilience concepts, with trainings.

Resilient MPA Networks – Canada, 2011

This learning exchange consisted of two parts: A pre-International Marine Conservation Congress (IMCC) workshop with 24 participants that focused on solving problems around MPA network design and implementation and a half-day symposium with 120 attendees. This symposium included a presentation of resilience science and application of advances to management decisions.

Pacific Training of Trainers – Palau, 2011

The second in a series of Training of Trainers (TOT) workshops included 17 managers from 12 countries and territories in the Western Pacific islands. This two-part course consisted of an intensive, four-month online course that was mentored by global and regional experts on various course topics. Participants had weekly assignments and engaged in virtual discussions to further enhance their learning experience. This was followed by a week-long, in-person workshop to build skills in facilitation, communication, and resilient marine protected area design. Participants left the workshop with specific training action plans.

We are happy to announce that new coral restoration information and resources are coming soon to the Reef Resilience online toolkit and we’d like to hear from you! Please take this short survey and let us know what you need to be more effective in your work on coral restoration.

Because your response is important to us, we are giving away 5 copies of the new National Geographic book ‘Pristine Seas: Journey to the Ocean’s Last Wild Places’ by Enric Sala to participants. You will be prompted to enter into this raffle at the end of the survey.

Thank you for participating in our survey! Take the survey.

An Integrated Coral Reef Ecosystem Model to Support Resource Management under a Changing Climate

Ecosystem-based management is a useful management tool that considers both indirect and cumulative effects of added stressors to a system. Ecosystem models, especially those that consider physical and biological disturbances and human uses, can help to inform ecosystem-based management during planning and implementation stages. This study modified the Atlantis Ecosystem Model to quantify and predict the effect of added stressors on the Guam coral reef ecosystem. Specifically, the study focused on three main stressors: climate change, land-based sources of pollution (LBSP), and fishing. The study used the IPCC Fifth Assessment Report highest emission scenario to predict atmospheric COconcentrations and the RCP8.5 projection to predict sea surface temperatures. LBSP was predicted using previous data collected on Guam’s sediment and nutrient loads and river flow. Fishing predictions were based on historical catches. Short term (i.e. 30 years) and long term (i.e. 65 years) simulation tests were run for each stressor.

The short term tests revealed that fishing resulted in the greatest negative impacts with LBSP following close behind. Climate change became the dominant stressor in longer time scales with the bleaching threshold exceeded every year after year 48. It becomes clear that long-term high intensity disturbances from multiple stressors limits and sometimes even prevents ecosystem recovery. Limiting frequency, intensity, and number of stressors can significantly increase reef resilience. This study revealed that reducing LBSP and increasing water quality can delay climate-related impacts for up to 8 years while buying time for the corals to adapt to higher temperatures. The Atlantis Ecosystem Model and others like it can be used to provide a wealth of knowledge to inform ecosystem-based management decisions on both regional and global levels.
