Abstract : The practice of dynamite fishing is common throughout all Southeast Asia, representing one of the main cause of reef degradation in the Philippines. In 2016 Sulubaai Environmental Foundation established a 40 ha Marine Protected Area (MPA) on Pangatalan Island (Shark Fin Bay) and designed a Sulu-Reef Prosthesis (SRP) made out from concrete in order to restore the degraded local reef. From 2017 to date SEF has deployed more than 200 SRPs on different coral rubble patches inside the MPA. In detail, SEF located a variety of SRPs 1000 (0.37 m2), SRPs 700 (0.28 m2) and SRPs 450 (0.2 m2), for a total of 178 m2 of artificial surface available for recruitment. This new restoration technic allowed to attach more than 1600 coral fragments belonging to 15 coral genus for a total amount of 28 different species. Results shows 76.63% survivorship rate with an attachment rate higher than 70%. Growing trend (Ecological volume) of branching forms seems significative influenced by the starting size while massive and thin forms did not show any differences between size groups. This new technic has the potential to facilitate resiliency of numerous reefs within coral repartition areas, since it allows to work with different genus increasing and/or maintaining the local biodiversity.

Abstract : Sulubaai Environmental Foundation (SEF), a Filippino non-profit organization created in 2012, has been devoted to implement ecosystem protection through targeted actions together with a self- sufficient sustainable development in Pangatalan Island (Shark Fin Bay). Before 2012 vegetation was exploited to produce charcoal, a very impacting activity that left only 306 trees on the island. Marine surveys revealed a similar situation underwater, with more than 60% of coral reef turned into rubble with a direct decrease in fish biomass. During time SEF replanted over 50,000 of native plants and 9.000 of mangrove trees. One goal of SEF is to increase the protection of natural resources. For this reason a Marine Protected Area has been implemented in 2016 and a coral restoration project has started. 85% of the electricity used on the island comes from 20 kW solar-powered system making Palangatan Island a zero-Carbon emission place. Food comes from a 2 ha organic farm initiated and developed by the foundation on the main land nearby the island. Water used on the island comes from the mountain nearby thanks to a gravity-based system, making water use 100% green. SEF is promoting up-cycling of materials in order to reduce the ecological footprint: thus SEF re-uses dismantle wood from old buildings of the surrounding villages and material waste (e.g. iron, wood) is donated to who can re-use it. We believe that with its zero-carbon emission policy and eco-friendly actions SEF can be considered has an example for Biosphere Reserve strategies implementation considering ecosystems conservation, sustainable development and overexploited natural resources restoration.

Abstract : Since the 1970s, ecological engineering has been practiced with an increasingly wide range of tools. It relies in particular on the choice of techniques mimicking degraded ecosystems, while respecting ecological trajectories as best as possible. It is used for many ecosystems.We tackle the subject of restoring coral reefs and associated ecosystems through an inventory of ecological engineering techniques and projects, carried out in France and abroad. This work follows on from two IFRECOR documents: “La restauration récifale: guide pratique à l’usage des décideurs et aménageurs” by Porcher, Job and Schrimm (2003) and “Restauration récifale : concepts et recommandations” by Edwards and Gomez (2007). It is intended to be concise and practical in order to address a large audience, of elected officials, of instructor services within administrations or design offices. The objective is to facilitate information and the dissemination of practices.
