The Impact

<p>With climate change becoming more widely understood, we are beginning to see how this phenomenon is impacting on our ability to live coastally. Coastal properties represent some of the most expensive real estate in the country, however these properties are being battered by increasing storm surges causing coastal erosion and decay to the land on which they sit. This is resulting in people fighting to keep their homes out of the water, along with an increasing need for a solution to keep the water out of their homes. In Raumati, sea walls began appearing in the 1950s with people blocking their individual properties from the ocean with wooden log walls. These walls have continued to get larger, higher and more solid until they have become the rock accumulation, stone path and concrete walls that stand today along almost the entire length of the Kapiti Coast.  The impact of such walls is that, while they protect the land immediately behind them, they cause greater issues further down the coast, causing sections of the coastline to deteriorate at a far more accelerated rate. The aim of this project will be to put an end to the Kapiti sea wall by addressing the site at the southern end of Raumati where this erosion is becoming increasingly evident. Here, the delicate sand dunes are being eaten away by heightened storm surges and an ever-increasing sea level.  Rather than looking at it as a negative effect, this thesis will explore the opportunities that are opened by this decay. The project proposes the reinstating and re-wetting of the once drained wetlands that lie behind the natural dunes. Above these wetlands, a ranger’s hut will act as a home, embassy and church within Queen Elizabeth Park. This allows for a greater sense of custodianship, with more people coming, going and staying within the park. The project outcome will be a building that combines public and private spaces. It will allow for the fluctuation in sea levels to interact with and become a part of the building, rather than being excluded through traditional approaches to dealing with climate change on coastlines. Hence, this ranger’s hut will put an end to the sea wall.</p>

Ports constitute a significant influence in the economic activity in coastal areas through operations and infrastructures to facilitate land and maritime transport of cargo. Ports are located in a multi-dimensional environment facing ocean and river hazards. Higher warming scenarios indicate Europe’s ports will be exposed to higher risk due to the increase in extreme sea levels (ESL), a combination of the mean sea level, tide, and storm surge. Located on the west Iberia Peninsula, the Aveiro Port is located in a coastal lagoon exposed to ocean and river flows, contributing to higher flood risk. This study aims to assess the flood extent for Aveiro Port for historical (1979–2005), near future (2026–2045), and far future (2081–2099) periods scenarios considering different return periods (10, 25, and 100-year) for the flood drivers, through numerical simulations of the ESL, wave regime, and riverine flows simultaneously. Spatial maps considering the flood extent and calculated area show that most of the port infrastructures' resilience to flooding is found under the historical period, with some marginal floods. Under climate change impacts, the port flood extent gradually increases for higher return periods, where most of the terminals are at high risk of being flooded for the far-future period, whose contribution is primarily due to mean sea-level rise and storm surges.

AbstractImportant aspects for understanding the effects of climate change on tropical cyclones (TCs) are the frequency of TCs and their tracking patterns. Coastal areas are increasingly threatened by rising sea levels and associated storm surges brought on by TCs. Rice production in Myanmar relies strongly on low-lying coastal areas. This study aims to provide insights into the effects of global warming on TCs and the implications for sustainable development in vulnerable coastal areas in Myanmar. Using TC records from the International Best Track Archive for Climate Stewardship dataset during the 30-year period from 1983 to 2012, a hot spot analysis based on Getis-Ord (Gi*) statistics was conducted to identify the spatiotemporal patterns of TC tracks along the coast of Myanmar. The results revealed notable changes in some areas along the central to southern coasts during the study period. These included a considerable increase in TC tracks (p value < 0.01) near the Ayeyarwady Delta coast, otherwise known as “the rice bowl” of the nation. This finding aligns with trends in published studies and reinforced the observed trends with spatial statistics. With the intensification of TCs due to global warming, such a significant increase in TC experiences near the major rice-producing coastal region raises concerns about future agricultural sustainability.

The Impact

Abstract The increase in sea levels, as a result of climate change in territorial aspect will have a potential impact on two major issues – maritime zones and land territory. The latter goes into the heart of the theory of the state in international law as it requires us to confront the problem of complete and permanent disappearance of a State territory. When studying these processes, one should take into account the fundamental lack of appropriate precedents and analogies in international law, especially in the context of the extinction of the state, which could be used for guidance in this respect. The article analyses sea level rise impact on baselines and agreed maritime boundaries (in particular taking into account fundamental change of circumstances rule). Furthermore, the issue of submergence of the entire territory of a State is discussed taking into account the presumption of statehood, past examples of extinction of states and the importance of recognition in this respect.

Security Issues

There is an international consensus that climate change is caused by human activities which substantially increase the atmospheric concentration of greenhouse gases.The ill-effects of climate change are droughts which adversely affect the global poor who are engaged in agriculture; storm surges which destroy local infrastructure, housing and crops; and the rise of sea levels which adversely affect the inhabitants of small island states which could eventually be totally submerged. Military strategists and intelligence analysts are preparing for future conflicts likely to be caused by environmental security issues.The objects of this article are: (i) to evaluate the ill-effects of climate change as a matter of global justice, (ii) to consider whether future generations have the right not to suffer from the ill-effects of climate change, and if so, (iii) to evaluate the relevant conceptions of global justice, and (iv) to assess critically whether international law provides effective preventive responses to climate change and environmental security threats.Finally, a monist-naturalist conception of global justice privileging human dignity as one of its guiding principles is proffered as a solution to the problems raised by the mechanisms of dealing with the ill-effects of climate change and the attendant environmental security issues under international law.

Abstract An increase in the global mean sea is predicted during the 21st century as a consequence of global average temperature projections. In addition, changes in the strength of atmospheric cyclonic storms may alter the development of storm surges, exacerbating the risks to coastal communities. Based on the fact that the interest and range of papers are growing on this topic, this study aims to present the global scientific production status of studies that have correlated climate change and the impact of storm surges on the coastal zone leading to erosion and flooding (inundation) via a bibliometric analysis. We analyzed 429 papers published in journals between 1991 and February 2021 from the Scopus database. Through the VOSviewer and Bibliometrix R package, we describe the most relevant countries, affiliations, journals, authors, and keywords. Our results demonstrate that there has been an exponential growth in the research topic, and that authors from the United States and the United Kingdom are the most prolific. Among the 1454 authors found, 10 researchers published at least 5 papers on the topic and obtained at least 453 citations in the period. The most represented journals were the Journal of Coastal Research, Climatic Change, and Natural Hazards. We also found, and discuss, the lack of standardization in the choice of keywords, of which climate change, storm surge, and sea level rise are the most frequent. Finally, we have written a guide to facilitate the authors' bibliographic review.

The vertical telescopic breakwater(VTB), which is a new breakwater that permits the navigation of ships, remain at the bottom of the sea during calm and rise to the surface during tsunamis or storm surges. Kawai et al. (2017) and Arikawa et al. (2019) found that it is effective not only for swell waves, but also for long-period waves simulating tsunamis and storm surges by previous experiments and numerical analyses. However, there have been few studies on the performance of VTB by numerical calculations in actual ports using actual typhoons. In addition, sea levels and changes in characteristics of typhoon due to climate change are predicted to occur; hence, we are concerned about the damage in all quarters caused by storm surge inundation, especially at Tokyo. Therefore, in this study, we used hypothetical typhoons under worst-case scenarios and quantitatively evaluated the protection performance of VTB against hypothetical typhoons with different aperture rates of VTB in Tokyo Bay by the numerical simulation.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/qof5ixKqIiA

This article analyses the profound and rapid climate changes that have taken place worldwide in the past two decades and their effects on modern enterprise. Reducing greenhouse gas emissions and developing strategies to adapt to and counterbalance future impacts of climate change sustainably are among the most pressing needs of the world today. Global temperatures are predicted to continue rising, bringing changes in weather patterns, rising sea levels, and increased frequency and intensity of extreme weather events. Such climatic events can have a major impact on households, businesses, critical infrastructure and vulnerable sections of society, as well as having a major economic impact. Therefore, society must prepare to cope with living in a changing climate. The effects of a changing climate have considerable impacts on modern enterprises. In some parts of the world, these impacts are increasingly becoming evident.

&lt;p&gt;Climate change will lead to increases in the flood risk in low-lying coastal areas. Understanding the magnitude and impact of such changes is vital to design adaptive strategies and create awareness. In&amp;#160; the&amp;#160; context&amp;#160; of&amp;#160; the&amp;#160; CoDEC&amp;#160; project&amp;#160; (Coastal&amp;#160; Dataset&amp;#160; for&amp;#160; Evaluation&amp;#160; of&amp;#160; Climate&amp;#160; impact),&amp;#160; we&amp;#160; developed a consistent European dataset of extreme sea levels, including climatic changes from 1979 to 2100. To simulate extreme sea levels, we apply the Global Tide and Surge Model v3.0 (GTSMv3.0), a 2D hydrodynamic model with global coverage. GTSM has a coastal resolution of 2.5 km globally and 1.25 km in Europe, and incorporates dynamic interactions between sea-level&amp;#160; rise,&amp;#160; tides&amp;#160; and&amp;#160; storm surges. Validation of the dataset shows a good performance with a mean bias of 0-.04 m for the 1 in 10-year water levels. When analyzing changes in extreme sea levels for the future climate scenarios, it is projected that by the end of the century the 1 in 10-year water levels are likely to increase up to 0.5 m. This change is largely driven by the increase in mean sea levels, although locally changes in storms surge and interaction with tides can amplify the impacts of sea-level rise with changes up to 0.2 m in the 1 in 10-year water level.&lt;/p&gt;&lt;p&gt;The CoDEC dataset will be made accessible through a web portal on Copernicus Climate Data Store (C3S). The dataset includes a set of Climate Impact Indicators (CII&amp;#8217;s) and new tools designed to evaluate the impacts of climate change on different sectors and industries. This data service will support European coastal sectors to adapt to changes in sea levels associated with climate change. In this presentation we will also demonstrate how the C3S coastal service can be used to enhance the understanding of local climate impacts.&lt;/p&gt;

<p>The world is currently sitting on the brink of a massive upheaval as Climate Change continues to intensify. At this stage, there is no apparent turning back: the only remaining option is to adapt. While many countries are already feeling the effects, the most vulnerable lie within the Pacific Islands.  With 70% of the Samoan population living along their coastline (The World Bank, 2016), the country is identified as one of the most vulnerable Pacific Islands. It is prone to high waves and storm surges, along with tropical cyclones, which destroy livelihoods and housing, as well as claiming lives.  The traditional architecture of Samoa was originally built to withstand such weather events, but has not been adapting to resist the increased cyclone intensity and rising sea levels. The materials and building practices currently used within Samoa do not have the properties to resist these extreme weather events.  Western building practises have been introduced and into the Samoan construction industry, but has not yet successfully been integrated. Combinations of traditional and Western building practises are, instead, resulting in buildings more vulnerable than ever. This issue remains unresolved, with unsuitable housing remaining one of the largest dilemmas currently faced by Samoa’s inhabitants.  Samoa recently graduated from the classification: Least Developed Country, to be classified as a Developing Country (Pilot Programme for Climate Resilience). This places Samoa as one of the more developed nations of the Pacific, therefore encouraging Samoa to take the lead in resilience to the ever imposing effects of Climate Change. Samoa has a close relationship with both New Zealand and Australia and therefore has access to building expertise, education and materials. Why, then, is Samoa so lacking in architectural resilience to the effects of Climate Change?  This paper endeavours to investigate this gap and, in turn provide a potential resolution. These solutions could aid other Pacific countries as well as encouraging further architectural resilience that can then be mirrored by the remaining, vulnerable countries of the Pacific.  This thesis first investigates the question:  “Why has Samoan culture not developed stronger architectural resilience against Climate Change?”  This thesis then evolves to question:  “How can Samoan architecture be hybridised to influence increased architectural resilience against Climate Change?”</p>
