Using Modern Conservation Tools for Innovative Management of Coral Reefs: The MANACO Consortium

Coral reefs are under threat and innovative management strategies are urgently required. However, discoveries from innovative fields of coral reef research are rarely transposed in practical conservation actions. This is mainly due to the difficulties in knowledge exchange between scientists and conservation stakeholders. The ManaCo consortium (http://manaco.ird.nc/) is an international network federating conservation stakeholders and researchers in a common effort to preserve the coral reefs. The focus is on using modern tools to build a bridge between indigenous knowledge and scientific innovation. ManaCo aims to orientate research toward relevant conservation needs and to facilitate the transposition of research into concrete management strategies. This will allow to coordinate a collaborative response against coral reef decline. We invite anyone sharing the same interests in joining us.


INTRODUCTION
Over the last decades, coral reefs have suffered a major decline due to the degradation of water quality, the increase of disease and predation, and the rise of sea surface temperatures (Wilkinson, 2008;De'ath et al., 2012;Ateweberhan et al., 2013). In the most severe cases, anomalous heat waves have already caused local coral losses of up to 50% (Hughes et al., 2017). Climatic projections predict stressful environmental conditions to become more frequent in the years to come, jeopardizing the future of coral reefs (van Hooidonk et al., 2016).
Coral reef conservation requires innovation in management strategies to cope with these threats (Mumby and Steneck, 2008). Recent research innovation at the intersection of genetics, oceanography, remote sensing and computer science can provide valuable insights to reinforce conservation strategies (Maina et al., 2011;Beger et al., 2014;Magris et al., 2014;van Oppen et al., 2017). However, the transposition of these scientific developments into a conservation perspective is hindered for several reasons. First, there is insufficient training of decision makers in the aforementioned disciplines which in some cases (e.g., genetics) has nourished skepticism toward the scientific process (Frankham, 2010;Joost et al., 2011). Second, the main format for dissemination of research findings is scientific publications, which are often technical and difficult to interpret for a non-specialist reader (Bainbridge, 2014). Literature search is also a time-consuming task, and often articles may not be open access (Gossa et al., 2015). The use of software support (e.g., web applications) synthesizing information relevant for conservation has been advocated to fill these gaps (Hoban et al., 2013;Westgate et al., 2018). Another obstacle is often the difficulty of research projects in adequately representing the conservation situations for which they should provide solutions. This is due to the unbalance in scientific output between countries, that results in works covering spatial and temporal scales that are not necessarily relevant for other conservation contexts (Bainbridge, 2014;Rose et al., 2018). Furthermore, new guidelines for conservation should fit in with already established frameworks and acknowledge the importance of pre-existing preservation criteria (e.g., social importance, traditional knowledge; Roux et al., 2006). To do so, it is essential that the channel of communication between scientists, conservation managers and policy makers facilitates a multidirectional knowledge exchange (Roux et al., 2006;Bainbridge, 2014). The more frequent and sustained these exchanges, the greater mutual trust that develops (Roux et al., 2006). Last, lack of funding can be an obstacle to the transition from research to practical conservation actions (Knight et al., 2008). International collaboration can help mitigate this issue by boosting the application for common funds.

THE ManaCo CONSORTIUM
In December 2019, a symposium organized in Noumea (New Caledonia) gathered about 60 participants to discuss innovative approaches to reinforce coral reef conservation strategies. This meeting brought together scientists and reef conservation stakeholders from 13 countries distributed across the South and North Pacific, Caribbean, Indian Ocean and Europe (Figure 1). Reef preservation stakeholders reported the state of their local conservation activities, while coral researchers presented the highlights of their research work. By means of a questionnaire, attendees provided their opinions concerning the main obstacles encountered in the exchange between research and applied conservation. The most frequent issues mentioned were about the lack of clarity in communication, the unbalanced representativeness of scientific studies and social/economic pressures. The answers to the questionnaires prepared the ground for a round table discussion, where the need for joining forces was unquestioned by all attendees. This led to the signature of a letter of intent for the creation of the ManaCo consortium.
ManaCo stands for "Modern tools for innovative coral MANAgement and COnservation" 1 and is an international group that federates local communities, volunteers and stakeholders with researchers in a common effort to preserve the coral reefs. Its focus will be on using modern and easy-to-use tools to build a bridge between indigenous/local knowledge and scientific innovation, in particular to promote exchange and sharing of technical expertise, knowledge and resources between reef conservation stakeholders and researchers.

THE PLAN OF ACTION
The plan of the ManaCo consortium activities consists of two recurring phases (Figure 2). The first phase is the cross-talk between members to highlight trends and innovations in coral reef research and to point out critical issues in reef conservation. These discussions will take place during bi-annual face-to-face meetings and via virtual consultations coordinated through the consortium website. Based on these exchanges, members of the consortium will identify a specific research topic addressing a precise conservation issue, as well as the associated obstacles in the transfer of knowledge.
The second phase aims to overcome these obstacles. Three complementary instruments are proposed: (1) Development of tools using recent technologies: webapplications or online resources conceived to facilitate the access to scientific information relevant for specific conservation needs (e.g., see http://www.congressgenetics. eu/). The design of these tools should focus on developing intuitive platforms, self-empowering and open access (example in Box 1); (2) Training workshops: these events will be organized to promote knowledge transfer requiring dynamic exchanges. This can involve a wide range of topics, from the standardization of field procedures to training courses on specific software solutions; FIGURE 2 | Schematic view of the ManaCo plan of action. The plan of action is composed of two phases. During the first phase (gray box), the discussion between reef conservation stakeholders and researchers aims to identify a specific research topic addressing a precise conservation issue. In the second phase (under the gray box), a strategy is established to facilitate the inherent transfer of knowledge. The instruments used in this phase are the design of tools using recent technologies (web-app, online resources), training workshops or the application for joint funding. The expected benefits for researchers and reef conservation stakeholders are described in the red and green boxes, respectively.
(3) Funding applications for common projects: members will team up to define common projects promoting innovation in reef conservation. Joint responses to calls for proposal will be performed through the consortium, leveraging the interdisciplinarity and internationality of the ManaCo team.
BOX 1 | The digital reef adaptive potential evaluator (DRAPEAU). DRAPEAU is an example of a modern tool that will be developed in the frame of ManaCo. The round tables at the ManaCo symposium highlighted the difficulty in interpreting genetic studies on coral adaptation in a conservation perspective. The goal of DRAPEAU is to make such information easily accessible to coral reef stakeholders working on any reef system. The foundations of this tool lay in the observation that reefs recurrently exposed to stressful conditions develop resistance. Seascape genomics predicts the potential for adaptation to environmental conditions measured by remote sensing (e.g., sea water temperature variations, pH, turbidity levels, proximity to populated areas; Selmoni et al., 2020). DRAPEAU will allow to explore these predictions trough an intuitive "click-on-map" interface. The user can customize the calculations for a given area of interest and for a given set of species. An interactive mode will also allow to evaluate the predicted impact of the location of marine protected areas on the other reef areas. An online tutorial will allow the users to familiarize with the functionalities of the app. All the predictions are exportable in various formats, therefore ensuring compatibility with pre-existing conservation frameworks. A video demonstration of DRAPEAU is available in the Supplementary Material.

EXPECTED BENEFITS
The plan of action of the ManaCo consortium is expected to bring mutual benefits for all the actors involved in coral reef conservation and research. From a researcher point of view, the ManaCo activities will facilitate application of research work in concrete conservation actions. This collaboration will also provide valuable feedback from the field that will improve the efficiency of the conservation measures proposed as well as the scientific knowledge. In addition, the participation in round tables gathering different stakeholders of reef conservation will promote the uptake of research work among the general public.
On the other hand, reef conservation stakeholders will take advantage of a proactive context to discuss specific conservation needs. Insights for conservation will be more relevant for local requirements, and be available in an accessible format. Furthermore, the ManaCo tools will allow reef conservation stakeholders to personally define and customize preservation guidelines and therefore ensure the compatibility with traditional methods.

OPEN MEMBERSHIP
The expertise and the roles of the members of the consortium transcend the fields of coral conservation and research: we can boast representatives of local communities, volunteers, decision makers of marine conservation, coral reef ecologists, physiologists, geneticists, oceanographers, etc. These actors join the ManaCo consortium from all around the world, from small islands territories to large countries (Figure 1). To date, ManaCo team include members from Australia, Cook Islands, Fiji, France, Guadeloupe, Japan, La Réunion, New Caledonia, French Polynesia, Solomon Islands, Switzerland, Tonga, Vanuatu and Wallis and Futuna.
ManaCo membership is open to any coral reef actor, and can be requested directly on the ManaCo website (see text footnote 1).

CONCLUSION
The future of coral reefs is under threat and the need for innovative solutions is echoing worldwide. This global challenge can only be tackled by collaborative responses with solutions adapted to the needs and peculiarities of local contexts, such as the Transnational Red Sea Center (TRSC; Kleinhaus et al., 2020), the Southeast Florida Coral Reef Initiative (SEFCRI 2 ), the Coral Triangle Initiative (CTI 3 ) or the Coral Reef Alliance 4 . Like the ManaCo consortium, these networks coordinate collaborative efforts, and they promote the exchanges between actors involved in coral reef conservation and research. A desirable step in the future is to establish a link between these different networks, and it is with this in mind that a representative of the TRSC was present in Noumea to participate in the Manaco Workshop.
