Special Issue Information

Dear Colleagues,

Coastal zones are facing critical pressures due to climate change and human intervention, highlighting that isolated strategies are insufficient for prevention. This Special Issue invites the academic community to submit research on coastal conservation and sustainability grounded in the integration of multi-scale solutions and using a solid empirical basis.

We seek contributions covering the entire coastal management cycle, from the monitoring and diagnosis of key variables (waves, hydrodynamics, shoreline evolution, and water quality), to the implementation of Nature-based Solutions (NbS). We welcome both successful and replicable local case studies and analyses of ecological connectivity at a regional scale.

The goal is to gather technical–scientific evidence that enables managers and stakeholders to conduct science-based management. We particularly welcome works that quantify gains in biodiversity and Ecosystem Services (ESs), such as coastal protection and Blue Carbon, demonstrating how rigorous conservation enables a resilient and adapted Blue Economy.

This study develops an integrated framework combining emergy analysis, carbon footprint accounting, and long short-term memory neural network modeling to investigate the effects of nature-based solutions on coastal ecosystem services and blue carbon functions from the perspective of river–coast connectivity. Three transects along a connectivity gradient were established in the Yellow River Delta, a typical large river delta in temperate China, covering riparian zones, estuarine transition areas, intertidal wetlands, and seagrass beds, with multi-source data collected over three consecutive hydrological years. Emergy–carbon coupling analysis based on this case study indicates that the high-connectivity transect shows a higher emergy yield ratio and net carbon sink compared to the low-connectivity transect, with salt marshes being most sensitive to connectivity change. Threshold analysis, specific to this delta, identifies a three-phase response pattern of carbon burial rate with increasing sediment connectivity, and reveals that wave attenuation efficiency declines notably when hydrological connectivity falls below approximately 0.5, although this value may vary across different coastal settings. A higher sea level rise rate raises the critical connectivity level required to maintain carbon sink function. The long short-term memory neural network trained on observational data achieves better prediction accuracy for blue carbon accumulation rates than traditional statistical methods, and SHAP value analysis suggests the possible existence of synergistic effects among connectivity dimensions. Based on these findings, three optimization strategies including tiered restoration, a dynamic pathway, and spatial configuration are proposed as case-specific recommendations for the Yellow River Delta. Framework-based simulations indicate the potential for connectivity-informed strategy adjustments to improve restoration efficiency under local conditions. This study concludes that river–coast connectivity represents an important lever regulating the ecological benefits of nature-based solutions, but emphasizes that all quantitative thresholds and benefit magnitudes reported here are case-specific estimates that require recalibration when applied to other coastal systems.
