the rate of sea-level rise. Reef restoration techniques can be applied to tidal pools and lagoons and marine biodiversity can be promoted with artificial structures such as floating rafts or tables raised off the bottom [Figure 5].
A coastal defence nature zone entails a greater encroachment of sea space as we are no longer planning a single sloped wall, but an entire area depending on how large the intertidal pools and lagoons will be. This opens up all kinds of opportunities as some of the lagoons can be designed for aquaculture use or managed fishery or to bring people closer to nature [Figure 4]. Enhancing coastal defence with nature is a response that ensures the benefit of ecosystem services. This includes additional protection external of the seawall. Most of all, the nature-enhanced coastal defence is a proactive way to address Sustainable Development Goal 14 (Life below water).
