“…Adaptation implies a human intervention through the establishment of policies that aim at a sustainable development of the territories based on an egalitarian and fair society (Klein et al, 2003). They must allow the development of new adaptive policy pathways (Rocle et al, 2020) while accepting a significant degree of uncertainty as to the future development of the system (Redman and Kinzig, 2003).…”

Abstract. The ongoing phenomenon of climate change is leading to an upsurge in the number of extreme events. Territories must adapt to these modifications in order to protect their populations and the properties present in coastal areas. The adaptation of coastal areas also aims to make them more resilient to future events. In this article, we examine two strategies for adapting to coastal risks: holding the coastal line through hard constructions such as seawalls or ripraps and the managed retreat of activities and populations to a part of the territory not exposed to hazards. In France, these approaches are financed by a solidarity insurance system at the national level as well as local taxes. These solidarity systems aim to compensate the affected populations and finance implementation of the strategies chosen by local authorities. However, the French mainland coast generally attracts affluent residents, the price of land being higher than inland. This situation induces the presence of inequalities in these territories, inequalities which can be maintained or reinforced in the short and medium term when a defense strategy based on hard constructions is implemented. In such a trajectory, it appears that these territories would be less resilient in the long term because of the maintenance costs of the structures and the uncertainties relating to the hazards (submersion, rising sea levels, erosion). Conversely, with a managed-retreat strategy, inequalities would instead be done away with since property and populations would no longer be exposed to hazards, which would cost society less and would lead these territories towards greater resilience in the long term. Only one social group would be strongly impacted by this strategy in the short term when they are subjected to a managed retreat to another part of the territory.

“…However, several agriculture and hydro-power dams were constructed on these rivers, as well as deep water harbours, blocking the transport of sediment downstream. Although some countries are implementing expensive mitigation strategies locally, a collaborative international effort would certainly deliver more benefits [53,54] with a reduced cost [55]. This teleconnection must be considered in coastal management.…”

The current retreat of the world's coastline has a profound impact on human activities and ecosystems. The scientific community has primarily focused on the potential impact of sea level rise. At the global scale, the contribution of river sand loads to coastal erosion has been overlooked. Here we present the first global sand pathway model from land to sea. Our model reveals that sand tends to accumulate towards tropical regions. We show that the recent shoreline evolution is significantly controlled by the imbalance in the sand budget, challenging the idea that sea level rise due to climate change is currently the main driver of coastal erosion. Our model highlights that the significant reduction in sand supply due to tens of thousands of river dams and its consequences on coastal erosion could be avoided by an effective sustainable management policy.

“…Dampak sosiologis juga merupakan dampak sekunder akibat kerusakan fisik. Secara sosiologis masyarakat di wilayah terdampak abrasi akan cenderung berubah, baik pola kehidupan individu maupun secara kelompok (Rocle et al, 2020;Sangha et al, 2019). Secara individu masyarakat menjadi lebih tertutup dan kurang percaya diri dalam membaur dengan masyarakat yang tidak terdampak.…”

Perubahan secara social kemasyarakatan terjadi pada kebiasaan-kebiasaan masyarakat sebelum dan setelah terdampak abrasi (Montero & Batista, 2020;Rocle et al, 2020). Sebelum terdampak abrasi masyarakat aktif melaksanakan kegiatan social dan gotong royong tetapi setelah terdampak abrasi maka kegiatan social kemasyarakatan menjadi jauh berkurang.…”

<p><em>On the one hand, the coastal area promises abundant natural resources, but on the other hand, there are potential threats of disaster for the people living in that area. Coastal erosion or abrasion is a threat/danger that harmful to communities in coastal areas in Indonesia. One of the areas affected by abrasion in Indonesia is Rembang Regency. This study attempted to analyze the physical and social impacts of abrasion in the Rembang Regency. This study was conducted qualitatively by utilizing Ikonos High-Resolution Satellite Imagery, field surveys, and interviews as the basis for the analysis of the impact of the abrasion disaster. Respondents in this study were communities and government officials in areas affected by abrasion which were determined by purposive sampling technique. The results of the data analysis show that the physical impacts of abrasion are classified into four categories, namely heavy damage, moderate damage, minor damage, and no damage, while the social impacts are in the form of psychological, sociological, and economic disturbances which have implications for decreasing welfare. Therefore, an in-depth analysis is needed to determine the abrasion disaster management policy in Rembang Regency.</em></p>
