“…Equally, eco-engineered habitats can be retrofitted onto existing infrastructures (Dafforn, Mayer-Pinto, Morris, & Waltham, 2015; Figure 2b). For instance, in coastal cities that are densely populated there may be insufficient space to create or restore habitats for coastal defence .…”

Climate change is increasing the threat of erosion and flooding along coastlines globally. Engineering solutions (e.g. seawalls and breakwaters) in response to protecting coastal communities and associated infrastructure are increasingly becoming economically and ecologically unsustainable. This has led to recommendations to create or restore natural habitats, such as sand dunes, saltmarsh, mangroves, seagrass and kelp beds, and coral and shellfish reefs, to provide coastal protection in place of (or to complement) artificial structures. Coastal managers are frequently faced with the problem of an eroding coastline, which requires a decision on what mitigation options are most appropriate to implement. A barrier to uptake of nature-based coastal defence is stringent evaluation of the effectiveness in comparison to artificial protection structures. Here, we assess the current evidence for the efficacy of nature-based vs. artificial coastal protection and discuss future research needs. Future projects should evaluate habitats created or restored for coastal defence for cost-effectiveness in comparison to an artificial structure under the same environmental conditions. Cost-benefit analyses should take into consideration all ecosystem services provided by nature-based or artificial structures in addition to coastal protection. Interdisciplinary research among scientists, coastal managers and engineers is required to facilitate the experimental trials needed to test the value of these shoreline protection schemes, in order to support their use as alternatives to artificial structures. This research needs to happen now as our rapidly changing climate requires new and innovative solutions to reduce the vulnerability of coastal communities to an increasingly uncertain future.

Summary Loss of marine habitats due to urbanisation has been met with growing research efforts to mitigate ecological impacts through eco‐engineering. Research in this area has focused on scientific and engineering outcomes, not considering that seawalls are a socially driven insertion into the environment. Further, management concerns when employing eco‐engineering projects include public opinion regarding the aesthetic value of enhanced structures. It is therefore important for ecologists working in urban systems to understand how the public connects with the environment. Here, we used surveys to quantify perceptions of marine environmental issues and attitudes towards an example of eco‐engineering research from Sydney Harbour, Australia. We also evaluated the effect of disclosing the costs of enhancing seawalls to participants regarding their support for the initiative. Results showed there was high support for applied management to improve biodiversity. This result is promising for the implementation of future eco‐engineering projects. Understanding social values towards our coastlines and new conservation initiatives will provide end users with the tools to optimise coastal management plans. In summary, consideration of public values in urban conservation is essential for effective management.
