“…Luther (2013) opined that landward migration of the coastline frequently disrupts human operations by endangering roads, houses, and other coastal infrastructure used for fishing, agriculture, and transit. It may also cause changes in coastal ecosystems (Unguendoli et al, 2023). Similarly, deposition and seaward displacement of the coastline may pose new obstacles to human activities as well as changes to the natural ecosystem (Atkinson et al, 2016).…”

“…Climate change can seriously impact the survival of communities whose livelihoods rely on coastal infrastructure and fisheries (Hailegiorgis et al, 2018). Unguendoli et al (2023) intimated that climate change has put several coastal communities under unprecedented strain by altering their resource base without giving them enough time for adaptation. While coastal communities have developed and evolved many adaptation techniques over several generations to survive, Hailegiorgis et al (2018) are of the view that any change in resources may have a huge impact on even highly esteemed and accepted practices and may result in population relocation as well as other serious humanitarian implications.…”

Climate change poses a significant threat to coastal communities, particularly those reliant on coastal infrastructure. Rising sea levels and increasingly severe weather events endanger coastlines across Canada, a nation with over 243,000 km of coastline. Indigenous communities, with their long history of coastal resource utilization, are especially vulnerable. This study investigates the social, economic, and environmental impacts of coastal erosion and flooding in Channel-Port aux Basques, Newfoundland. Hurricane Fiona’s devastating impact on the community in 2022 underscores the urgency of adaptation strategies. The research employed a multi-pronged approach: data analysis from weather and census sources, a literature review, a vulnerability assessment using established frameworks, and agent-based modeling using NetLogo software. Findings reveal significant social impacts, including displacement, emotional distress, and loss of public spaces. While existing adaptation measures like shoreline armoring offer some protection, their effectiveness in the face of stronger storms and projected sea level rise remains questionable. The agent-based model predicts increased coastal erosion, with households within 8 meters experiencing erosion within the first year at current sea level rise rates. The study recommends developing a comprehensive plan to mitigate coastal erosion risks. Potential solutions include sea walls and promoting sustainable land-use practices that prioritize coastal ecosystems and managed retreat strategies. The research concludes by emphasizing the need for context-specific, participatory adaptation strategies to enhance coastal community resilience in the face of a changing climate.

“…This optimization would require the use of hydrological and geochemical models to simulate the effect of NBS in resolving various issues raised by the WEF nexus at the basin scale. Models that have already been used in the literature to simulate the impact of NBS implementation include Karst-SWAT, HEC-RAS, QUESTOR, and the XBeach hydro-morphological model (Unguendoli et al, 2023;Hutchins et al, 2024;Liao et al, 2024). Lilli et al (2020b) used a combination of Karst-SWAT and the HEC-RAS to design the restoration of a riparian forest and measures for flood protection for the Koilaris River Basin.…”

The water ecosystem food (WEF) nexus duly acknowledges the complex interdependencies among water, ecosystems, and food production, underscoring nature based solutions (NBS) as an efficacious strategy for navigating these interconnections. In this research, four different NBS (terraces, riparian forest, livestock management and agro ecological practices) were assessed in terms of their impact to WEF nexus. The Karst-SWAT and the one-dimensional integrated critical zone (1D-ICZ) models were used to simulate the impact of NBS on water quantity and quality as well as on soil ecosystem services of Koiliaris River Basin, which serves as an illustrative example of a basin that has experienced severe soil and biodiversity degradation. The Karst-SWAT model showed that a combination of NBS of terraces and riparian forest can reduce soil erosion and the sediment load by 97%. The 1D-ICZ model successfully simulated the soil-plant-water system and showed that agro ecological practices affect biomass production, carbon and nutrient sequestration, soil structure and geochemistry.

NI can reduce erosion and flood risks to communities (Spalding et al, 2014;Chausson et al, 2020), provide recreational opportunities (Winter et al, 2019) and improve human health and well-being (Williams, 2017), while providing habitat for vulnerable wildlife like migratory birds and a variety of aquatic organisms (Unguendoli et al, 2023).…”

Beneficial use of sediments to restore a Chesapeake Bay marsh island

Despite rapidly expanding interest in the use of natural coastal habitats for their ability to protect against erosion and flooding, implementation of coastal natural infrastructure (NI) projects has been limited to date. Uncertainty over how the benefits of NI will change over time as they mature and adapt to changing environmental drivers, and a lack of well-documented demonstrations of NI, are often cited as roadblocks to their widespread acceptance. Here, we begin to fill that knowledge gap by describing implementation and early (3 years post-implementation) monitoring results of an NI project at Swan Island, MD. Swan is an uninhabited marsh island in mid-Chesapeake Bay, United States whose position renders it a natural wave break for the downwind town of Ewell, MD. Prior to project implementation, Swan had experienced significant losses in areal extent due to subsidence and erosion. To reverse this trend, the island was amended with dredged sediments in the winter of 2018–2019. The overarching goal was to preserve the Island’s ability to serve as a wave break and make it more resilient to future sea level rise by increasing the elevation of the vegetated platform, while also increasing the diversity of habitats present. A monitoring program was implemented immediately after sediment placement to document changes in the island footprint and topography over time and to evaluate the extent to which project goals are met. Data from the initial three years of this effort (2019 through 2022) indicate an island that is still actively evolving, and point to the need for rapid establishment of vegetative communities to ensure success of coastal NI.
