The Incorporation of Biophysical and Social Components in Coastal Management

Abstract

Change is inherent in coastal systems, which are amongst the most dynamic ones on Earth. Increasing anthropogenic pressure on coastal zones interferes with natural coastal dynamics and can cause ecosystem imbalances that render the zones less stable. Furthermore, human occupation of coastal zones often requires an uncharacteristic degree of stability for these inherently dynamic coastal systems. Coastal management teams face multifaceted challenges in protecting, rehabilitating and conserving coastal systems. Diverse monitoring schemes and modelling tools have been developed to address these challenges. In this article, we explore various perspectives: the integration of biophysical, ecological and social components; the uncertainties of diverse data sources; and the development of flexible coastal interventions. We propose general criteria and guidance for an Ecosystem-based Management (EbM) to coastal management, which aims primarily at adaptation to global change and uncertainties, and to managing and integrating social aspects and biophysical components based on the flows of energy and matter.

Distant-Source Swells Cause Coastal Inundation on Fiji’s Coral Coast

“…Another possible solution to improve the model could be to apply a varying friction coefficient depending on marine habitat across the model domain (Passeri et al, 2018). Coral reefs are complex systems in terms of geometry and bottom roughness; hence, incorporating this complexity into the numerical model might improve the results (e.g., Osorio-Cano et al, 2019;Reguero et al, 2019;Silva et al, 2019).…”

Biological and physical drivers of bio-mediated sediment resuspension: A flume study on Cerastoderma edule

“…It happens at a local scale, but the effects may be important for broader landscape processes (Widdows & Brinsley, 2002;Bentley Sr, et al, 2014;Walles, et al, 2015). The bioturbators' ecosystem engineering [sensu (Jones, et al, 1994;Jones, et al, 1997)] of wet sediment dynamics impacts the short-and long-term development of coastal geomorphology (Winterwerp, et al, 2018;Gao, 2019), ecology (Zhu, et al, 2016;Lukwambe, et al, 2018;Mermillod-Blondin, et al, 2018;Savelli, et al, 2019) and services provided to the human society (Barbier, 2013;Bouma, et al, 2014;Lin, et al, 2018;Silva, et al, 2019). The role of bioturbation should hence be taken into account in order to implement Ecosystem-Based management of coastal areas (Braeckman, et al, 2014;Van der Biest, et al, 2020).…”

How Effective Were the Beach Nourishments at Cancun?

“…Over time, the methodologies used for these solutions have evolved, e.g., [7]. In the past, the most frequently applied techniques were based on hardening the coast, by means of dikes, breakwaters, groins, etc.…”
