Biodiversity and ecosystems are foundational to the Sustainable Development Goals (SDGs). They are explicitly recognized in SDG 14 (Life Below Water) and SDG 15 (Life on Land), which aim to conserve and sustainably use aquatic and terrestrial ecosystems. Biodiversity and healthy ecosystems also support SDG 2 (Zero Hunger) by providing the variety of life that underpins agricultural productivity. They contribute to SDG 6 (Clean Water and Sanitation) by providing essential water filtration services, and to SDG 3 (Good Health and Well-being) by regulating disease and offering potential sources for medical discoveries. Moreover, these biological resources play a significant role in climate change mitigation and adaptation, linking to SDG 13 (Climate Action). Hence, the protection of biodiversity and ecosystems is essential to achieving multiple SDGs.
Ecology plays a central role in the management and conservation of ecosystems. However, as coral restoration emerges as an increasingly popular method of confronting the global decline of tropical coral reefs, an ecological basis to guide restoration remains under-developed. Here, we examine potential contributions that trophic ecology can make to reef restoration efforts. To do so, we conducted a comprehensive review of 519 peer-reviewed restoration studies from the past thirty years.
