“…The non-hydrostatic model can be applied for the reliable simulation of beach responses to sea level rise and storm surges [59,60]. Furthermore, erosion hotspots indicate the erosive characteristics of sandy beaches predominately [61,62], so it is feasible to use the non-hydrostatic model to identify erosion hotspots during the beach profile evolution. The numerical results may help optimize local restoration effort to mitigate erosion at the hotspots.…”

With the recent development from grey infrastructures to green infrastructures, artificial reefs become more popular in coastal protection projects. To investigate the responses of beach profile evolution to the presence of an artificial reef, a non-hydrostatic model is established. Both hydrodynamic and morphodynamic evolution for the beach with and without an artificial reef are compared under regular wave conditions. In addition, the protected beach profile evolution by an artificial reef is discussed under irregular wave conditions. Three key parameters in non-hydrostatic simulation are considered for sensitivity analysis, including maximum wave steepness criterium (maxbrsteep), water depth factor (depthscale), and equilibrium sediment concentration factor (sedcal). The numerical results under regular wave conditions indicate that the artificial reef enhances wave attenuation by inducing wave breaking. In addition, the artificial reef reduces local flow velocity and offshore sediment transport by 51%, therefore decrease the total erosion by 53%. Over the artificial reef, wave skewness and asymmetry go through a drastic change. Under irregular wave conditions, short waves contribute to the wave energy mainly and reflection-induced standing wave effects decline considerably. It demonstrates that the artificial reef can protect the beach from regular and irregular waves by reducing erosion and offshore transport of suspended sediments. Moreover, in the wave breaking area, the increase of maximum wave steepness criterium may give arise to the wave height. The morphological evolution is more sensitive to water depth factor than equilibrium sediment concentration factor, because the former is a controlling factor for beach profile characteristics while the latter forms the sandbar varying irregularly in shape.

“…Legislative failure can result in the health of the land-water interface not receiving suitable attention from public institutions, society in general, and lawmakers in particular [31]. Consequently, coastal systems may suffer from poorly regulated development and construction practices, resulting in increased erosion and land speculation [51,52]. Additionally, marine areas and even coastal zones have been excluded from the vast majority of proposed bills and other scientific programs related to land-use planning.…”

“…The Congress has the potential to process a bill that connects the marine and terrestrial realms in a single legal instrument that regulates social uses, economic activities, and jurisdictional lines in coastal areas. Such a coastal law could be developed with consideration of the failures of similar efforts in other countries, i.e., [21,22,52], in order to avoid mistakes.…”

Latin America and the Search for a Coastal Law: Lessons from the Legislative Procedure in Colombia

In 2009, a network of scholars identified the legal framework associated with coastal management in eleven Latin American countries. They found an important lag in several countries, including Colombia. According to many scholars, a clear regulatory framework is of the utmost importance for integrated coastal management; however, the hurdles to reaching this goal have been poorly analyzed. This article aims to illustrate the challenges and barriers to legislate on coastal and marine issues in Colombia. The methodology and analysis used in this study can serve as an example to other Latin American countries. We combined comparative, documentary, and analytical research techniques to describe the current Latin American state-of-the-art legal framework. Additionally, from 16,224 gazettes (official records of the Congress of Colombia) we identified 80 bills concerning coastal and marine activities for a period of 17 years. However, only 2.1% of those bills addressed marine or coastal issues from the perspective of planning and management procedures. Instead the majority focused on social uses and economic activities. This research identified the difficulties that could be faced by a country in regulating its coast from an integrated perspective. These findings could support future procedures to approve coastal laws in Latin America and other countries on the world.

“…Some of the returned papers explore the legal and political tensions arising in attempting to implement managed retreat via land use planning or other legislative frameworks [21,22,29,32,[113][114][115], with findings including challenges with community acceptance, prioritization of private property laws and rights, and political barriers to implementation via land use planning systems (see also [90]). Rocle & Salles [116] offer a unique and informative study of experimental planned retreat in which local councils/municipalities were asked to simulate retreat decision-making practices between 2012 and 2015.…”

“…Not all, nor sometimes any, of these options for coastal climate change adaptation are viable. Many stagnate owing to political [14,15,22,23,31] and legal [3,13,15,17,18,29,[32][33][34][35] tensions. When combined with varied and often conflicting social values [3,5] protect, accommodate and retreat options for climate adaptation and governance have been often been incremental, and where less incremental, certainly polarizing.…”

Vulnerable locations, such as coastlines, are at a high risk of loss and damage. Such places will suffer deleterious impacts as climate change impacts are increasingly realized. As societies try to adapt to these impacts, managed or planned retreat—aimed at moving people and assets away from vulnerable locations—is gaining increased attention. Despite this increased attention, systematic literature reviews of the retreat literature remain scarce. This paper undertakes such review and uncovers a marked increase in retreat scholarly research papers in the past 5 years. An analysis of 135 managed and planned retreat journal articles is completed. Findings include a strong emphasis on regional or local case studies exploring governance, policy or institutional settings and levers across a range of geographies. Property rights and market interventions, such as compensation schemes, evidence the prevalence of neoliberal predilections. This emphasizes the importance of renewed engagement with political economy scholarship vis-à-vis climate change adaptation, also supported by the sharp increase in the evidenced social and environmental justice impacts. This article is part of the theme issue ‘Nurturing resilient marine ecosystems’.
