<p><strong>Abstract:</strong></p><p>Climate change is one of the most pressing challenges of the 21st century and is likely to increase migration of the marginal communities from the coastal areas throughout the world. It is projected that 200 million people worldwide will be climate refugees by 2050. Owing to high exposure and poor adaptive capacity, low-lying coastal areas and islands in developing countries are the most vulnerable to the impacts of climate change. Therefore, it is imperative to understand how climate change is affecting the livelihoods, in turn, driving the migration in these regions.</p><p>The present study focuses on the Sundarbans region located along the coastal belt of West Bengal (India) as a part of Ganga-Brahmaputra mega delta. It is also a home of 4.7 million poor people, who earn below US$10 per month. The region is an exceedingly flat, low-lying, alluvial plain highly exposed to sea level rise, storm surge, tornedoes, cyclonic activity, riverbank erosion, salinization and subsequent mangrove depletion. Due to the climatic hazards, the basic livelihoods are at risk and their strategies towards livelihood collection remains largely unknown. Therefore, the present study provides insights into the nexus among climate stimuli, livelihood risks, and households’ strategies in the region, with special emphasize on climate change.</p><p>The study is based on field survey of 150 respondents representing migrant and non-migrant coastal communities from Gosaba, Basanti and Hingalganj block using structured questionnaires. More than 70% of respondents stated that livelihood risks mainly from climate change impacts as the major reason for inter-state migration, which is the main source of income supporting livelihood in the region. This environmental displacement in the Sundarbans region symbolizes the failure of adaptation to mitigate climate change induced sea level rise increasing the exposure to coastal flooding and storm surges, salinization, and erosion.  This study discusses potential mitigation strategies to combat the impacts of climate change on livelihoods of the coastal communities in the region.</p>

Coastal California has witnessed persistent sea-level rise (10-20 cm) along its southern and central open ocean coastal sections and in San Francisco Bay over the past century. This paper aims to understand the perceptions of local coastal managers in California of current inundation-related risks, the added risks from climate change, and vulnerability to the growing coastal problems. We also explore the extent to which coastal managers are beginning to think about and tackle these increasing management challenges. Survey results presented here suggest that inundation already creates critical management challenges in California, but other, non-inundation-related coastal problems also vie for managers' attention. Despite high awareness of global warming and moderately good understanding of potential impacts of climate change on coastal areas, currently pressing issues and limited staff time and resources constrain their ability to begin dealing with the growing risks from sea-level rise. The sobering conclusion is that California is inadequately preparing for the impacts of climate change on coastal areas at this time. Local government will need substantial support from state and federal agencies if the level of preparedness for climate change and other inundation-related risks is to be elevated in the future.

The sea level is rising due to global warming in response, by and large, to anthropogenic activities. Coastal communities along the Gulf of Guinea are low lying which makes them more vulnerable to rising sea level. Due to the topography of the Gulf of Guinea, the coastal belt is a highly erosive sandy barrier system that is susceptible to flooding. In West Africa, highlyproductive ecosystem like mangroves, estuaries, and deltas, that form the vital socio-economic activities like trade, tourism, fisheries and industrial growth due to the oil and gas development are found in these coastal communities. Therefore, majority of the population in West Africa who live in these mega cities along the coast face possible threats. Thus, climate adaptation is the only option to address these future threats as reduction in the emission of carbon dioxide (CO2) and other green house gases is not enough for now to prevent global warming which leads to sea level rise. Thus, this study seeks to investigate from other research works, how sea level rise has affected these coastal communities along the Gulf of Guinea and how the communities are adapting to these challenges to new ways of living. It concludes with a recommendation on a climate change based framework.

A scientific scenario paper was prepared ahead of the Gulf of Maine (GOM) 2050 International Symposium to review and summarize possible weather-related and sea-level changes within the GOM as a result of climate change. It is projected that the GOM will experience warming temperatures, continued sea-level rise, and changes to storm characteristics and related elements such as precipitation and waves in the intermediate term, by approximately 2050. Coastal communities within the GOM region are particularly vulnerable to the anticipated impacts of climate change. This article aims to provide context on some of the consequential impacts that may occur from the changes projected within the area.

As coastal communities around the globe contend with the impacts of climate change including coastal hazards such as sea level rise and more frequent coastal storms, educating stakeholders and the general public has become essential in order to adapt to and mitigate these risks. Communicating SLR and other coastal risks is not a simple task. First, SLR is a phenomenon that is abstract as it is physically distant from many people; second, the rise of the sea is a slow and temporally distant process which makes this issue psychologically distant from our everyday life. Virtual reality (VR) simulations may offer a way to overcome some of these challenges, enabling users to learn key principles related to climate change and coastal risks in an immersive, interactive, and safe learning environment. This article first presents the literature on environmental issues communication and engagement; second, it introduces VR technology evolution and expands the discussion on VR application for environmental literacy. We then provide an account of how three coastal communities have used VR experiences developed by multidisciplinary teams—including residents—to support communication and community outreach focused on SLR and discuss their implications.

Climate change and sea level rise are realities that are upon us and which will profoundly impact the lives and basic rights of millions of coastal residents all over the world. As the law stands both at the international and at certain national levels, the basic human rights of the climate displaced are not adequately protected. This paper identifies two possible displacement scenarios, based on the continued availability/non-availability of land in the face of sea level rise and other climate change impacts; namely, the sinking Small Island Developing States phenomeon, where land disappears and there is no surplus land to support habitation, and all other cases, where the coastal land is battered severely but it can be re-utilized through appropriate adaptation measures or even if coastal frontage land disappears there is still land available inland. On this basis, the paper proposes three possible solutions: (1) bilateral or regional treaties to facilitate resettlement of the inhabitants of sinking Small Island Developing States, (2) appropriate coastal climate change adaptation implemented via integrated coastal zone management and (3) creation of new arrangements under the international climate change regime to provide financial assistance and technological support to respond to both situations. Even though the primary focus of this paper is on coastal communities in South Asia, the lessons that it offers are relevant to other coastal contexts as well.

<p>Sea-level rise induces a permanent loss of land with widespread ecological and economic impacts, most evident in urban and densely populated areas. The eventual coastline retreat combined with the action of waves and storm surges will end in more severe damages over coastal areas. These effects are expected to be particularly significant over islands, where coastal zones represent a relatively larger area vulnerable to marine hazards.</p><p>Managing coastal flood risk at regional scales requires a prioritization of resources and socioeconomic activities along the coast. Stakeholders, such as regional authorities, coastal managers and private companies, need tools that help to address the evaluation of coastal risks and criteria to support decision-makers to clarify priorities and critical sites. For this reason, the regional Government of the Balearic Islands (Spain) in association with the Spanish Ministry of Agriculture, Fisheries and Environment has launched the Plan for Climate Change Coastal Adaptation. This framework integrates two levels of analysis. The first one relates with the identification of critical areas affected by coastal flooding and erosion under mean sea-level rise scenarios and the quantification of the extent of flooding, including marine extreme events. The second level assesses the impacts on infrastructures and assets from a socioeconomic perspective due to these hazards.</p><p>In this context, this paper quantifies the effects of sea-level rise and marine extreme events caused by storm surges and waves along the coasts of the Balearic Islands (Western Mediterranean Sea) in terms of coastal flooding and potential erosion. Given the regional scale (~1500 km) of this study, the presented methodology adopts a compromise between accuracy, physical representativity and computational costs. We map the projected flooded coastal areas under two mean sea-level rise climate change scenarios, RCP4.5 and RCP8.5. To do so, we apply a corrected bathtub algorithm. Additionally, we compute the impact of extreme storm surges and waves using two 35-year hindcasts consistently forced by mean sea level pressure and surface winds from ERA-Interim reanalysis. Waves have been further propagated towards the nearshore to compute wave setup with higher accuracy. The 100-year return levels of joint storm surges and waves are used to map the spatial extent of flooding in more than 200 sandy beaches around the Balearic Islands by mid and late 21st century, using the hydrodynamical LISFLOOD-FP model and a high resolution (2 m) Digital Elevation Model.</p>

Local authorities in New Zealand have a significant responsibility to their communities for managing the effects of sea level rise due to climate change. However, while most local authorities are well engaged and have a clear understanding of issues arising from sea level rise, 73% report that their organisations do not receive enough direction from central government on how to respond. Territorial authorities in particular are seeking a stronger lead, such as legislative reform, clearer and more directive policy, clarification of responsibilities, or a national environmental standard on coastal hazard management. Central government direction is seen as critical to achieve a nationally consistent and equitable approach for coastal communities. This article summarises how this could be addressed, and identifies key challenges facing local government in adapting to sea level rise and climate change.
