Abstract Many natural marine habitats are decreasing in extent despite global conservation and restoration efforts. In contrast, built structures, such as hardened shorelines, offshore energy aquaculture infrastructure, artificial reefs, increasing extent—and, some locations, represent over 80% of nearshore, structured habitat. When introduced into the seascape, structures inevitably interact with habitats, but these not typically designed to support systems. This approach often results overall harm systems, further impeding goals. However, there is growing recognition within ocean management engineering community that can be strategically minimize their negative impacts potentially ecosystems associated biota. We synthesize best available science provide bright spot examples how leveraging mimic or facilitate help recover biodiversity, augment ecosystem services, rehabilitate degraded providing positive outcomes for people nature a changing climate. Despite spots, we caution have environmental consequences should used lieu conventional habitat justify destruction habitats.

Current extent and future opportunities for living shorelines in Australia

Living shorelines aim to enhance the resilience of coastlines hazards while simultaneously delivering co-benefits such as carbon sequestration. Despite potential ecological and socio-economic benefits living over conventional engineered coastal protection structures, application is limited globally. Australia has a long diverse coastline that provides prime opportunities for using beaches dunes, vegetation, biogenic reefs, which may be either natural ('soft' approach) or with an structural component ('hybrid' approach). Published scientific studies, however, have indicated use in Australia. In response, we combined national survey interviews practitioners grey peer-reviewed literature search (1) identify barriers shoreline implementation; (2) create database projects based on sources other than literature. Projects included were those had primary secondary goal assets from erosion and/or flooding. We identified 138 through means sampled starting 1970; number increasing time particularly since 2000. Over half total (59 %) considered successful according their initial stated objective (i.e., reducing hazard risk) 18 % could not assessed success information available. Seventy percent received formal informal monitoring. Even absence support construction Australia, discovered local regional increases use. This suggests are learning on-the-ground, however more generally it was few examples being made available, suggesting barrier sharing among agencies at broader scale. A can increase knowledge globally develop best practice informs technical guidelines different approaches helps focus attention areas further research.

Creating ecosystem buffers in intertidal zones, such as seagrass meadows, has gained increasing attention a nature-based solution for mitigating storm-driven coastal erosion. This study presents what-if scenarios using an integrated model framework to determine the effectiveness and strategies planting reduce The comprises two levels of simulation packages. first level is regional-scale coupled hydrodynamic that simulates processes specific storm provides boundary forces morphodynamic XBeach apply at next level, which nearshore morphological evolution. applied open coast Norderney German Bight North Sea. We demonstrate optimising location size meadows crucial increase efficiency onshore sediment erosion mitigation. For depth range, depending on storm's intensity, most significant reduction may not be achieved by starting meadow permits largest size. To maintain protection effect, density stem height should considered together, ensuring least 80 % compared unprotected coast. valuable insights design implementation transplantation solution, highlighting importance considering location, size, density, when protection.

Restoring estuarine ecosystems using nature-based solutions: Towards an integrated eco-engineering design guideline

The Science of The Total Environment, Год журнала: 2023, Номер 873, С. 162362 - 162362

Traditional solutions to estuarine flood risk management have typically involved the implementation of static ‘hard’ shoreline protection structures, often at expense natural landscape and societal ecosystem benefits they provide. In a changing climate, there is an increasing need restore these ecosystems, alternative measures in form Nature-based Solutions (NbS) are being considered. Guidance that balances ecology engineering required for NbS establish as self-sustaining ecosystems. this study, review guidelines was undertaken, revealing absence technical content bridging ecological values. Instead, most focus on project implementation, identifying aspects, providing frameworks investors managers. Integration outcomes within needed. A conceptual approach integrating eco-engineering aspects ecosystems proposed. This focuses critical thresholds parameter relationships associated with establishment, growth, recovery mortality, functionality NbS, efforts quantify changes development mitigation services. The documents how suggested between parameters can be adopted by practitioners short-term, medium-term, long-term. application multi-habitat restoration explored, including lifecycle timing ecosystem/design functionality. findings study demonstrate integrated design guideline research long-term success
