Abstract Climate change is presenting an ongoing and eminent threat to various regions, communities and infrastructure worldwide. In this study, the current and future climate impacts faced by Viet Nam due to Tropical Cyclones (TCs), specifically wind and surge, are evaluated, and different adaptation measures to manage this risk are appraised. The level of wind and storm surge risk was assessed focusing on three categories of assets: residential houses, agriculture, and people. The expected damage to these assets was then evaluated based on their exposure to the hazard under current and future climate scenarios. Physical adaptation measures such as mangroves, sea dykes, and gabions, and financial adaptation measures such as risk transfer via insurance were applied to the expected future risk and evaluated based on a socio-economic cost-benefit analysis. The output will give decision-makers the ability to make more informed decisions, prioritize the most cost-effective adaptation measures and increase physical and financial resilience. The results indicated significant TC exposure in future climate scenarios due to economic development and climate change that almost doubles the current expected damage. Surge-related damage was found to be many times higher than wind damage and houses had more exposure (value in total) than agriculture on a national scale. The physical adaptation measures are successful in significantly reducing the future wind and especially surge risk and would form a resilient strategy along with risk transfer for managing TC risks in the region.

<p>Climate Change has presented an ongoing and eminent threat to various regions, communities and infrastructure worldwide and in-turn increasingly pressuring national and local governments to take action. In the current study we identify and evaluate climate impacts faced by the city of Can Tho in Vietnam and the broader Mekong Delta and appraise preparedness options to manage today’s as well as future climate risk. We first, identify the climate risks in co-operation with various local, national and international stakeholders in the region. This is done on the current and future time scales under Socio-Economic Pathways (SSPs) as suggested in the current iteration of IPCC evaluation process. Based on these development pathways, we apply the Economics of Climate Adaptation (ECA) methodology to quantify the climate risks various sectors of the economy will be facing until 2050 with a focus on flood. Further we assess a range of possible adaption measures - including behavioral, environmental, physical as well as financial measures that can mitigate the identified risks by providing a cost-benefit analysis for each of the adaptation measures as well as for bundles thereof. The ECA methodology has proven to be an established tool to enhance our knowledge on the topic and its application in this specific context will enable stakeholders to strengthen societal resilience in the context of both socio-economic development and climate change.</p>

Lessons Learnt

This paper explores the lessons learnt from the Optimising Adaptation Investment projects for the Department of Climate Change and Energy Efficiency–it includes coastal settlements, water supply and rail infrastructure case studies. These projects are the first of their kind in Australia and are considered internationally as a leading example of economic cost benefit analysis. They have been used effectively to inform decision making on specific adaptation responses to climate change risks to existing and new infrastructure. The lessons learnt will be explored for offshore platforms, ports, rail, road, drainage, tailings dams, mine facilities, water, and power supply, which includes the following elements: What decision makers require to make informed decisions under the uncertainty of climate change impacts. Reducing the uncertainty through economic modelling and cost benefit analysis. Optimising the right timing and scale of various adaptation options. Benefiting from oil and gas infrastructure adaptation opportunities. To further support the elements above, the applied process for integrating climate adaptation into infrastructure planning, design and operation will be illustrated by AECOM project experiences. AECOM has completed more than 60 significant climate change risk and adaptation projects for mines, ports, water supply and treatment, energy generation, transmission and distribution, rail, road, and coastal settlements in Australia, including the report: Climate Change Impacts to Infrastructure in Australia for the Garnaut Climate Change Review.

AbstractGroundwater salinity, caused by over-extraction and aggravated by climate change, negatively affects crop productivity and threatens global food security. Poor farmers are vulnerable due to low adaptive capacity. A better understanding of their perceptions and adaptation is important to inform policies for successful adaptation. This paper represents an important study by exploring the same in Mewat, a salinity-affected socioeconomically backward district of northern India. The study uses a mixed-method approach with both secondary data and a primary survey of 250 farmers. A large number of farmers perceived negative impacts on water, crop, income, and assets; and adapt in various ways like water management, crop, and land management, livelihood diversification, and shift towards surface water irrigation. Perceived impacts differed between richer and poorer farmers, whereas adaptation measures varied across the educational, social, and economic backgrounds of farmers. Lack of awareness, education, skill development, and livelihood-opportunities are found to be hindrances, whereas institutional and infrastructural support as facilitators of adaptation. Comparing the findings with global experiences we argued that developed countries intervene more in the policy level and infrastructure, whereas in developing countries, adaptation strategies are local, context-specific, and low-cost. The insights from our study will be useful for intervention in Mewat and similar areas across the developing world. We further argue that farmers take adaptation decisions based on perceived impacts and cost-benefit analysis. Therefore, future research work on quantifying the negative impacts and cost-benefit analysis of various adaptation measures will be useful to ensure successful adaptation in the region and beyond.

Policy Goals

This study systematically reviews the scientific literature ([Formula: see text]) on cost-benefit analysis (CBA) of adaptation measures in cities and similar urban environments. The review is conducted to assess existing or proposed actions for dealing with impacts of drought, heat waves, sea-level rise, and pluvial and fluvial flooding. It includes over 30 measures related to structural, services, technological, informational and ecosystem-based approaches. The main findings demonstrate that CBA of adaptation measures across urban environments must contend with numerous long-term socioeconomic and climate change uncertainties. Subsequently, this has led to inconsistencies in valuation frameworks related to, for example, planning horizons, discount rates, non-market considerations and future scenarios. Results also indicate a clear gap in the literature on the economic valuation of adaptation measures in the Global South. Furthermore, few studies integrate equity dimensions while planning for adaptation. Extensions of CBA to account for key uncertainties will help policy makers to allocate (often scarce) resources more efficiently and limit the likelihood of maladaptation. Further inclusion of the magnitude and distributional effects of non-market impacts and greater civil society engagement in policy dialogues will also be vital for promoting just and equitable measures that balance adaptation alongside other policy goals such as mitigation, economic development, health and well-being.

AbstractTo design effective adaptation measures to a heating climate, decision-makers need a state-of-the-art, regional and sector-specific knowledge about future climate impacts. Tailoring this information to the needs of policymakers requires collaboration between scientists and stakeholders. A lot of literature on design principles and comprehension of scientific visualisations exists. However, the links between objective comprehension, perceived usefulness for communication and aesthetics of climate change impact maps have rarely been analysed in empirical studies. In a co-design effort together with stakeholders in adaptation planning and climate change communication experts, regional climate change impact maps were developed and published as open-access dataset. The comprehension, aesthetics and perceived usefulness of different map design features were qualitatively and quantitatively evaluated in a two-step survey. Designs with less information density were understood best, found most aesthetical and useful for communication practice. Uncertainties were deemed necessary by participants, but not understood well when combined with other variables on the same map sheet. Map understanding varied significantly with the cognitive difficulty of a task. This difference was robust over user groups. Co-designing maps at the science-policy interface have the potential to create more useful and comprehensible communication materials and thus supports adaptation planning with the best available information on future climate impacts.

The Status

Climate change has a strong influence on agriculture and will continue to do so in the years to come. As a result, significant social costs are generated. These effects may be eliminated by implementing various types of adaptation measures. However, the measures are also associated with costs and it is necessary to evaluate whether generated benefits and prevented climate change costs outweigh them. This contribution studies economic impacts of climate change in agriculture in the South Moravian region in a period of 2017–2040. Four scenarios are analysed based on combinations of the following states of a world (i) climate change worsens the current situation or there is no change; (ii) adaptation measures are implemented or the status quo is maintained. The scenarios are modelled based on an anthropocentric approach using a modified cost-benefit analysis and the concept of ecosystem services. The economic analysis covers investment costs, operating costs, loss of profits due to decreasing production and other costs. The benefits side consists mainly of regulation services prevented loss (thanks to lower soil erosion or better water retention), improved air quality as well as external benefits such as higher biodiversity. Based on measures effectiveness and costs, expected net present social benefits were calculated for each of the scenarios. The results showed that implementing the measures is always profitable regardless of climate change. Under no shift in climate change the estimated social loss until 2040 is 6.6 billion CZK with no measures implemented. If the situation regarding climate change becomes more serious, the net loss rises to 9.5 billion CZK. However, the implementation of adaptation measures leads to positive outcomes and is associated with net social benefits of 2.1 billion CZK if it is necessary to battle climate change and to barely positive outcome when climate change does not accelerate. The analysis confirms that implementation of adaptation measures is profitable either way (especially if climate change becomes more serious) and can serve as an argument in political decision-making as these measures appear to maintain sustainability of agricultural land use.

The Impact

AbstractChanges in land use and climate are the main drivers of change in soil organic matter contents. We investigated the impact of the largest policy-induced land conversion to arable land, the Virgin Lands Campaign (VLC), from 1954 to 1963, of the massive cropland abandonment after 1990 and of climate change on soil organic carbon (SOC) stocks in steppes of Russia and Kazakhstan. We simulated carbon budgets from the pre-VLC period (1900) until 2100 using a dynamic vegetation model to assess the impacts of observed land-use change as well as future climate and land-use change scenarios. The simulations suggest for the entire VLC region (266 million hectares) that the historic cropland expansion resulted in emissions of 1.6⋅ 1015 g (= 1.6 Pg) carbon between 1950 and 1965 compared to 0.6 Pg in a scenario without the expansion. From 1990 to 2100, climate change alone is projected to cause emissions of about 1.8 (± 1.1) Pg carbon. Hypothetical recultivation of the cropland that has been abandoned after the fall of the Soviet Union until 2050 may cause emissions of 3.5 (± 0.9) Pg carbon until 2100, whereas the abandonment of all cropland until 2050 would lead to sequestration of 1.8 (± 1.2) Pg carbon. For the climate scenarios based on SRES (Special Report on Emission Scenarios) emission pathways, SOC declined only moderately for constant land use but substantially with further cropland expansion. The variation of SOC in response to the climate scenarios was smaller than that in response to the land-use scenarios. This suggests that the effects of land-use change on SOC dynamics may become as relevant as those of future climate change in the Eurasian steppes.

The Cost

Abstract Among all the threats to global diversity, climate change is the most severe cause. According to the world’s biodiversity conservation organization, reptile species are affected mostly because the biological and ecological traits of the reptiles are strongly linked with climate. To prevent species extinction, we tried to develop a decision support system that incurs the costs and benefits of reintroducing a taxon from its origin to adapt environmental conditions to conserve it from its extinction. The model was developed by applying multiple linear regressions that take the climatic variables and species traits to determine the cost and benefits for the distribution of species. The effectiveness of the model was evaluated by applying it to the Indian Black Turtle, which is an endangered species list in India evaluated by the International Union for Conservation of Nature list. The model recommends moving the species, which is endangered, to the location where it can save itself from climate change. However, the framework demonstrates huge differences in the estimated significance of climate change, and the model strategy helps to recognize the probable risk of increased revelation to critically endangered species.
