Rising Sea Level

As a coastal district located in the Southeast of Ho Chi Minh City (HCMC), Vietnam, Can Gio is characterized by low average terrains ranging up to only 1.5m above the sea level. Impacted by climate change and sea level rise in recent years, certain neighborhoods in the Can Gio District have been facing the loss of their residential and arable lands, as well as undesired relocations. Together with riverbank and coastal erosion, this phenomenon has several negative impacts on the lives of people in residential areas and on their economic activities. This research uses a literature review and observation as the main methods to explore the experiences of sea level rise adaptive housing and thereby suggests certain solutions for the Can Gio District. The solutions include saving space for water, elevating floors, constructing with floating floors, and creating biological ditches and osmotic lines to help quickly drain flooded water. These solutions aim to protect people’s lives and houses against the rising sea level and ensure the sustainable development of the neighborhoods.

<p>Climate impacts increase with higher warming and evidence is mounting that impacts increase strongly above 1.5°C. Therefore, adaptation needs also rise substantially at higher warming levels. Further<strong>, </strong>limits to adaptation will be reached above 1.5°C and loss and damage will be inferred. Coastal Nature-based Solutions (NbS) have arisen as popular adaptation options, particularly for coastal developing economies and Small Island Developing States (SIDS), because of their lower overall costs compared to traditional grey infrastructure approaches such as seawalls and levees; their economic co-benefits through positive effects on sectors such as tourism and fisheries; and a broader desire to shift toward so-called blue economies. Two NbS of particular interest for coastal protection are: 1) coral reefs, which reduce coastal erosion and flooding through wave attenuation; and 2) mangroves, which provide protection from storms, tsunamis and coastal erosion. Although there is international enthusiasm to implement these solutions, there is limited understanding of the future viability of these ecosystems, particularly in their capacities as coastal adaptation service providers, in a warmer world.</p><p>In this presentation, we highlight how long and with how much coverage coral and mangrove ecosystems can provide coastal protection services for future climate scenarios, using air temperature and sea level rise as climate change indicators. A mathematical model for each ecosystem is developed, based on the physical parameters necessary for the sustainability of these ecosystems. We investigate the protective capabilities of each ecosystem under warming and sea level rise scenarios compatible with: below 1.5°C warming; below 2°C warming; warming based on current global commitments to carbon emissions reductions (3-3.5°C); and with no carbon mitigation (6°C). Results show what temperature and sea level rise values beyond which these ecosystems can no longer provide coastal protective services. These results have also been framed in a temporal window to show when these services may not be feasible, beyond which more costly adaptation measures and/or loss and damage may be incurred.</p>

Climate change and sea level rise scenarios for Vietnam was published by the Ministry of Natural Resources and Environment in 2012. According to the scenarios, when sea level rise by 1m, over 20% of Ho Chi Minh City will become flood risk area affecting more than half million people (7% of the city’s population). This urgent problem affecting so many people like that but accessing to this information of the inhabitants is very limited. Therefore, the research Using the 3D technology to build flood model on WebGIS helps to show visually water level, flood position and the risk area affected in different water level. The research did not analyze the aspects of climate change, just used the results of the scenarios combining with 3D model technology on WebGIS to build an application. The result is not only the tool to help local people to access easily with the visual information about water level but also the reference for relating research and applications.

Design-flood elevations with associated exceedance probabilities are often determined for coastal projects. Rising sea level introduces another design consideration that needs to be combined with the design-flood level. However, most sea level projections do not have exceedance probabilities that can be used in conjunction with the design flood to obtain total flood elevations with exceedance probabilities. This paper shows how to combine design-flood elevations with sea level rise projections that have exceedance probabilities, such as those of the Intergovernmental Panel for Climate Change (Bindoff et al 2007) or Houston (2012a), to obtain total elevations at desired exceedance probabilities over particular intervals.

Many of New Zealand’s urban settlements are likely to be affected by climate-induced hazards such as sea level rise, coastal erosion, flooding and rising groundwater levels, and some are already being affected. These communities face many physical, social, financial and emotional challenges, and there is significant potential for inequitable outcomes. To ensure successful adaptation, local authorities will need to adopt new approaches to engaging with communities that are exposed to these hazards.

This work aimed to develope sea level rise (SLR) scenarios in Ho Chi Minh City (HCMC) to 2100, corresponding to the scenarios of RCP2.6, RCP4.5, RCP6.0, and RCP8.5 and the approach mentioned in the AR5 report of the Intergovernmental Panel on Climate Change (IPCC) through SIMCLIM software, and the local water level data (updated to 2015). The results showed that the SLR in the coastal area of HCMC increased gradually over the years as well as the increase in greenhouse gas scenarios. In the period of 2025-2030, SLR would increase relatively equally among RCP scenarios. SLR in 2030 would increase about 12cm as compared to sea level in the period of 1986-2005 in all RCP scenarios. By 2050, the average SLR for the scenarios of RCP2.6, RCP4.5, RCP6.0, and RCP8.5 would be 21 cm, 21 cm, 22 cm, and 25 cm, respectively. The corresponding figures for 2100 would bee 43 cm, 52 cm, 54 cm, and 72 cm, respectively. The research results provide an important basis for calculations and assessments of impact and vulnerability due to the climate change to socio-economic development in HCMC.

Abstract We summarize the potential nature and scope of economic effects of climate change in Alaska that have already occurred and are likely to become manifest over the next 30–50 years. We classified potential effects discussed in the literature into categories according to climate driver, type of environmental service affected, certainty and timing of the effects, and potential magnitude of economic consequences. We then described the nature of important economic effects and provided estimates of larger, more certain effects for which data were available. Largest economic effects were associated with costs to prevent damage, relocate, and replace infrastructure threatened by permafrost thaw, sea level rise, and coastal erosion. The costs to infrastructure were offset by a large projected reduction in space heating costs attributable to milder winters. Overall, we estimated that five relatively certain, large effects that could be readily quantified would impose an annual net cost of $340–$700 million, or 0.6%–1.3% of Alaska’s GDP. This significant, but relatively modest, net economic effect for Alaska as a whole obscures large regional disparities, as rural communities face large projected costs while more southerly urban residents experience net gains.

Climate change impacts, sea level rise, and changes to the frequency and intensity of storms, in particular, are projected to increase the coastal land and assets exposed to coastal erosion. The selection of appropriate adaptation strategies requires an understanding of the costs and how such costs will vary by the magnitude and timing of climate change impacts. By drawing comparisons between past events and climate change projections, it is possible to use experience of the way societies have responded to changes to coastal erosion to inform the costs and selection of adaptation strategies at the coastal settlement scale. The experience of implementing a coastal protection strategy for the Gold Coast’s southern beaches between 1964 and 1999 is compiled into a database of the timing, units, and cost of coastal protection works. Records of the change to shoreline position and characteristics of local beaches are analysed through the Bruun model to determine the implied sea level rise at the time each of the projects was completed. Finally, an economic model updates the project costs for the point in the future based on the projected timing of sea level rise and calculates a net present value (NPV) for implementing a protection strategy, per km, of sandy beach shoreline against each of the four representative concentration pathways (RCP) of the Intergovernmental Panel on Climate Change (IPCC) to 2100. A key finding of our study is the significant step-up in expected costs of implementing coastal protection between RCP 2.6 and RCP 8.5—from $573,792/km to $1.7 million/km, or a factor of nearly 3, using a social discount rate of 3%. This step-up is by a factor of more than 6 at a social discount rate of 1%. This step-up in projected costs should be of particular interest to agencies responsible for funding and building coastal defences.

Climate scenarios show that Mediterranean areas will be affected by torrential patterns of rain, that can cause difficulties in urban life in coastal areas, mainly due to the draining systems and to the sea-level. Lisbon is on the estuary of Tagus river, which would be probably affected by run-off and by the forecasted rising sea-level. Redesigning its relationship with water, trying to make this urban area more resilient, becomes crucial and asks to study run-off and sea-level rise for 2100 and for intermediate steps, to adapt the urban life and its spaces to the occurring scenarios.
