“…The cost parameter c embeds both variable costs of nourishment sand and the fixed cost, which is divided among the total number of oceanfront properties in the community. By folding both into one parameter, our model predicts continuous rather than periodic nourishment (Smith et al 2009b), and can be interpreted as averaging nourishment over discrete intervals. To determine the cost parameter c we estimate the cost function using data on nourishment projects in North Carolina between 1939-2006(PSDS 2006.…”

Climate change threatens to alter coastline erosion patterns in space and time and coastal communities adapt to these threats with decentralized shoreline stabilization measures. We model interactions between two neighboring towns, and explore welfare implications of spatial-dynamic feedbacks in the coastal zone. When communities are adjacent, the community with a wider beach loses sand to the community with a narrower beach through alongshore sediment transport. Spatial-dynamic feedbacks create incentives for both communities to nourish less, resulting in lower long-run beach width and lower property values in both communities, a result that parallels the classic prisoner's dilemma. Intensifying erosion-consistent with accelerating sea level rise-increases the losses from failure to coordinate. Higher erosion also increases inequality in the distribution of benefits across communities under spatially coordinated management. This disincentive to coordinate suggests the need for higher-level government intervention to address a traditionally local problem. We show that a spatially targeted subsidy can achieve the first best outcome, and explore conditions under which a second-best uniform subsidy leads to small or large losses.

“…It is used worldwide as a form of soft engineering to protect coastal development from the impacts of unmanaged erosion (Greene and Fund 2002). It serves to maintain the value of coastal investments (Landry and Hindsley 2011) and retain the value of beach amenity to tourism and recreation (Klein et al 2004;Smith et al 2009), (Fig. 5a).…”

Coastal protection measures, case study (Mediterranean zone, Egypt)

The rapid erosion in most coastlines is considered a major problem not only in Egypt, but also around the world. The main causes are due to anthropogenic activities and/or coastal hydrodynamics. The coastal zone suffers from sedimentation, accretion, and pollution problems as well as the side effect of climate change. The climate change will increase sea level rise, salt water intrusions, and storm surge. Major efforts has been exerted to manage coastal erosion problems and to restore coastal capacity in order to protect housing, infrastructure and the cultivated land. These problems were encountered with various types of hard structures, but most of these methods response were limited due to lack in evaluation of the entire ecological situation. This encouraged the coastal engineers to think about new types of environmental friendly structures work better with ecological situation. In this study, the protection measures worldwide is reviewed and divided mainly into four groups, hard, soft, combined, innovative measures. The usage and side effect of each type is mentioned briefly. It is clear that there is a predominant approach towards the soft engineering, the eco-engineering techniques, or combination between them in order to enhance the ecological situation. Recently, there are several efforts to apply these new technologies to protect the coastal zone as well as the environment by taking into consideration the effect of climate change. These new approaches in coastal protection are multi used, environmentally friendly, easy to modify and maintain, and efficient from an economic perspective. Previous efforts in solving coastal problems in Egypt are analyzed and discussed taking into consideration the experience of similar cases worldwide. It is clear that the environmental friendly coastal structure is more suitable to solve most of our coastal problems with saving our ecosystem and reduce the protection cost.

“…A more intense storm on top of SLR has the potential to generate an even more catastrophic storm surge. (Smith et al, 2009;Gopalakrishnan et al, 2011), based on local perceptions of beach erosion rates in recent years , at each 10-km town in the domain. In the top panels (A i , A ii ), nourishment intervals are uniform alongshore.…”

“…For example, economic analyses of beach replenishment over the short term (25-50 years) invariably find that the benefits engendered by protection of property and support for coastal recreation justify replenishment costs (Bell, 1986;Parsons and Powell, 2001;Landry et al, 2003;Smith et al, 2009), whereas many coastal geologists and environmentalists have espoused support for climate adaptation strategies that embrace retreat in the face of erosion (Riggs and Ames, 2003;Pilkey and Dixon, 1996). To some extent, the two extreme views attempt to address different issues: one is focused on the near term while the other highlights the reality of the long-term future.…”
