Ecosystem design as an avenue for improving services provided by carbonate producing marine ecosystems

Ecosystem Design (ED) is an approach for constructing habitats that places human needs for ecosystem services at the center of intervention, with the overarching goal of establishing self-sustaining habitats which require limited management. This concept was originally developed for use in mangrove ecosystems, and is understandably controversial, as it markedly diverges from other protection approaches that assign human use a minor priority or exclude it. However, the advantage of ED lies within the considered implementation of these designed ecosystems, thus preserving human benefits from potential later disturbances. Here, we outline the concept of ED in tropical carbonate depositional systems and discuss potential applications to aid ecosystem services such as beach nourishment and protection of coastlines and reef islands at risk from environmental and climate change, CO2 sequestration, food production, and tourism. Biological carbonate sediment production is a crucial source of stability of reef islands and reef-rimmed coastlines. Careful implementation of designed carbonate depositional ecosystems could help counterbalance sea-level rise and manage documented erosion effects of coastal constructions. Importantly, adhering to the core ethos of ED, careful dynamic assessments which provide a balanced approach to maximizing ecosystem services (e.g., carbonate production), should identify and avoid any potential damages to existing functioning ecosystems.

Ecosystem Design is an approach that focuses on meeting human needs for ecosystem services by constructing designed ecosystems that can benefit from potential disturbances. It has potential applications in tropical carbonate depositional systems to address issues such as beach nourishment, protection of coastlines and reef islands at risk, CO2 sequestration, food production, and tourism. Careful implementation of designed carbonate depositional ecosystems can help counteract sea-level rise and manage erosion effects caused by coastal constructions.
