Coastal Risk

AbstractInfrastructure is necessary to protect and provide the goods and services required by humans. As coastal green infrastructure (CGI) aims to respect and work with natural processes, it is a feasible response to mitigate or avoid the consequences of coastal squeeze. The concept of CGI is receiving increased attention of late due to the challenges facing us, such as climate change, population growth and the overexploitation of natural resources on the coast. Terms which may be applied to encourage the construction of infrastructure, or to minimize the responsibility for poorly made decisions, often induce misunderstanding. In this paper, the concept of CGI and its use in solving coastal problems is reordered. Four categories are proposed, according to the degree of naturalness of the project: Nature reclamation, Engineered ecosystems, Ecologically enhanced engineering, and De-engineering/Relocation. Existing coastal risk evaluation frameworks can be used to design many types of CGI. Key concepts, challenges and good practices for the holistic management of coastal squeeze are presented from the analysis of successful and unsuccessful CGI projects worldwide.

Estuarine and coastal waters are acknowledged centres for anthropogenic impacts. Superimposed on the complex natural interactions between land, rivers and sea are the myriad consequences of human activity – a spectrum ranging from locally polluting effluents to some of the severest consequences of global climate change. For practitioners, academics and students in the field of coastal science and policy, this book examines and exemplifies current and future challenges: from upper estuaries to open coasts and adjacent seas; from tropical to temperate latitudes; from Europe to Australia. This authoritative volume marks the 50th anniversary of the Estuarine and Coastal Sciences Association, and contains a prologue by founding member Professor Richard Barnes and a short history of the Association. Individual chapters then address coastal erosion and deposition; open shores to estuaries and deltas; marine plastics; coastal squeeze and habitat loss; tidal freshwaters – saline incursion and estuarine squeeze; restoration management using remote data collection; carbon storage; species distribution and non-natives; shorebirds; Modelling environmental change; physical processes such as sediments and modelling; sea level rise and estuarine tidal dynamics; estuaries as fish nurseries; policy versus reality in coastal conservation; developments in Estuarine, coastal and marine management.

Nesting Beaches

The Intergovernmental Panel on Climate Change predicts that sea levels will rise by up to 0.82 m in the next 100 years. In natural systems, coastlines would migrate landwards, but because most of the world’s human population occupies the coast, anthropogenic structures (such as sea walls or buildings) have been constructed to defend the shore and prevent loss of property. This can result in a net reduction in beach area, a phenomenon known as “coastal squeeze”, which will reduce beach availability for species such as marine turtles. As of yet, no global assessment of potential future coastal squeeze risk at marine turtle nesting beaches has been conducted. We used Google Earth satellite imagery to enumerate the proportion of beaches over the global nesting range of marine turtles that are backed by hard anthropogenic coastal development (HACD). Mediterranean and North American nesting beaches had the most HACD, while the Australian and African beaches had the least. Loggerhead and Kemp’s ridley turtle nesting beaches had the most HACD, and flatback and green turtles the least. Future management approaches should prioritise the conservation of beaches with low HACD to mitigate future coastal squeeze.

Rising Sea Levels

<p><b>The ecological resilience of the intertidal margins of many cities is increasingly under pressure due to climatic shifts and urbanisation. As rising sea levels push the high-water mark landward, many coastal species are prevented from migrating inland due to natural or man-made barriers. This results in a phenomena known as ‘coastal squeeze’. </b></p> <p>Pauatahanui Inlet, Porirua supports a diverse ecosystem of aqua-fauna, micro invertebrates and wading birds that rely on the shallow saltmarsh habitat within the estuary. However, with sedimentation from the surrounding catchments slowly filling up the inlet along with and predicted tidal inundation from sea level rise, the future of this coastline is uncertain. </p> <p>Rather than attempting to solve or secure a fixed future for the coastline, as is the prevailing anthropocentric response, this design led research seeks to respond to these human induced pressures by working with the cyclical phenological processes and ecological interactions occurring within the harbour. The research ambition is to co-create a shared public tidal realm. </p> <p>This objective is tested through the design of a coastal boardwalk for the Pauatahanui Inlet. Unlike human-focused boardwalks, this infrastructure is designed with the capacity to adapt as the tidal edge shifts, in either direction, while facilitating movement for all forms of life to traverse the harbour. The research attempts to surpass perceived barriers between nature and culture with an emergent inquiry into the poetic nature of the site itself. Here landscape design practice is developed towards the creation of social capital as occurring between species, while ensuring the natural ecosystem (and the life it supports) has the capacity to adapt to potential climate related changes.</p>
