This chapter delves into adaptation options broadly classified as structural/physical, institutional and social. Building upon these, it focusses on adaptation forms: autonomous versus planned, reactive versus proactive, short run versus long run, private versus public and incremental versus transformational. In doing so, it draws attention to the complexity of climate change adaptation.

The purpose of this paper is to present a framework for estimating the costs of adaptation to climate change impacts on ecosystems.

While existing studies on costing adaptation base themselves on either the financial flows on conservation or the costs of specific adaptation measures at the global level, the methodology presented here takes into account the impacts on ecosystems, the identification of vulnerable areas, and adaptation options at a more regional level.

The framework is then applied to forest ecosystems in India. The authors find that the total adaptation costs for forest ecosystems in India until 2085 are in the range of $1.34‐2.32 billion.

The key contribution of this paper is the proposal that for any robust estimation of adaptation costs, people should take into account the regional level impacts and the multiple adaptation options linked to those impacts.

This paper aims to present a new framework for climate change vulnerability, impact and adaptation (VIA) assessment. Greater attention has been given in recent years to the importance of conducting climate change VIA assessment prior to, or as part of, climate change adaptation strategies and projects. A VIA assessment provides decision-makers and project developers with information on the location and causes of vulnerability based on local knowledge and scientific data, so that effective adaptation responses that are targeted and site-specific can be designed. A challenge facing practitioners in this field is the lack of clear methodologies or agreed frameworks on how to conduct a VIA assessment.

This paper presents a VIA methodological framework that has been developed through three sub-regional pilot assessments on vulnerability and impacts of climate change, as part of the Regional Gateway for Technology Transfer and Action on Climate Change in Latin America and The Caribbean.

While it is recognized that methodologies and tools may differ depending on the unique local context of the study area and sector under analysis, there are key components that every assessment needs to consider.

The framework proposed can assist practitioners to deliver outputs from VIAs that are holistic, and provide the most appropriate type of information required for effective, context-specific adaptation responses.

This paper aims to develop a framework to assist the identification of robust adaptation options that account for uncertainty in future climate change impacts for the water sector.

The water evaluation and planning (WEAP) tool, is to identify future water resource vulnerability in the Glore sub‐catchment within the Moy catchment in the West of Ireland. Where water stress is evident, a detailed hydrological modelling approach is developed to enable an assessment of the robustness to uncertainty of future adaptation decisions. WEAP is coupled with a rainfall runoff model (hydrological simulation model), and forced using climate scenarios, statistically downscaled from three global climate models to account for the key sources of uncertainty. While hydrological models are widely applied, they are subject to uncertainties derived from model structure and the parameterisation of the catchment. Here, random sampling of key parameters is employed to incorporate uncertainty from the hydrological modelling process. Behavioural parameter sets are used to generate multiple future streamflow series to determine where the bounds within future hydrological regimes may lie and the ranges within which future adaptation policy pathways need to function.

This framework allows the identification of adaptation options that are robust to uncertainty in future simulations.

Future research will focus on the development of more site‐specific adaptation options including soft and hard adaptation strategies. This approach will be applied to multiple water resource regions within Ireland.

A robust adaptation assessment decreases the risk of expensive and/or mal‐adaptations in a critical sector for society, the economy and the aquatic environment.

The purpose of this paper is to review and document some of the climate change impacts which may burden the African continent, and to suggest policy options for adaptation.

The paper presents a comprehensive review of published papers on climate change impacts and adaptation.

It has been documented that by 2050, the world will have to limit emissions of all greenhouse gases to the equivalent of 400 GT of carbon in order to stand a 75 per cent chance of avoiding more than 2°C of warming. This is practically impossible because there are not enough resources and technology to achieve that target. Even if all of the emissions are stopped in next few years, it will take the next 40 years for the world to follow its current trend before full recovery. Thus, climate will continue to change, its impacts will continue to increase and Africa is placed as the most vulnerable continent. The only best solution is that the vulnerable population should be first in line for support to adapt to climate change impacts. In such instances adaptation policy should recognise and support a wide range of options for building resilient and sustainable livelihoods, enhancing opportunities available for adaptation, without ignoring the need to address the existing developmental challenges.

The paper is a valuable input towards the preparation of adaptation policy in developing countries.

This paper relied on review of secondary data (published articles) thus providing critical findings from a number of field studies.

The sharing economy (SE) is significantly affecting traditional companies, which have felt a need to adapt their business model. The aim of this study is to identify the different types of adaptation developed by companies within a SE context, and to examine how they relate to their characteristics.

A content analysis involving 149 real-world adaptation cases was carried out, after which a Kruskal–Wallis test and a multiple correspondence analysis were used to explore the relationships between the types of adaptation identified, the business characteristics and the strategic decisions taken for these adaptations.

Through the analyses proposed in the study, the main conclusions suggest that the way companies adapt to SE is related to business characteristics and the strategic decisions taken for these actions, demonstrating throughout the article what types of adaptations are made depending on variables such as sector of activity or business orientation.

This study is the first to examine the variables affecting the decisions among traditional companies in response to the SE. In addition, this work explores the SE from the business point of view, shedding light on the participation in SE by traditional companies.

This study aims to explain the existing adaptation practices in an urbanized sub-region in the lower Chao Phraya River basin (CPRB) across different scales and dimensions. It offers an overview of water hazards in urban areas along the river basin to discover ways to deal with and recover from hazards via understanding the implications of existing and potential practice for the mitigation of hydrological hazards.

First, this study collected current adaptation strategies and measures from interview, focus group discussion, workshop organization, etc. to get the current adaptation strategies/measures for the whole CPRB and each specific area. Second, this study identified a set of criteria for evaluation from review of current publications and official reports. Then, the current adaptation strategies/measures were examined through a set of criteria to obtain the current situation of existing practices. Finally, analysis of key challenges and opportunities was done to propose supporting guidelines to reduce hydrological risks and incorporate further adaptation measures needed to boost resilience in the area.

Adaptation methods should focus on mixed adaptation, which integrates structural, social, organizational and natural adaptation, and to develop multi-dimensional collaboration. The adaption strategy has restricted the usage of some technologies and technical know-how, particularly in the area of climate change. As a result, intentional adaptation to become more inventive is required, to reduce hazards and improve disaster-response capacity. The various adaptation measures should be more integrated or more adaptive and to achieve greater cohesion and mutual benefit of individual measures, such as community-based adaptation or community-driven slum upgrading.

Hydrological risks are wreaking havoc on social, economic and environmental elements, particularly river flood, flash flood and drought in the Asia-Pacific region. Twenty-two existing adaptation options were evaluated with evaluation criteria such as scales of risks/impacts reduction, benefits of environmental and socio-economic and institutional aspects. The findings highlight the current situation of existing practices, key challenges and opportunities, which emphasized on natural-based solutions, raising knowledge and awareness and lessons learned on adaptation of hydrological risks. The existing adaptation measures will be suggested as supporting guidelines and master plans to minimize the hydrological risks.

Climate change is affecting people displacement in Bangladesh by both sudden environmental events and gradual environmental change. This paper aims to assess the sustainable adaptation measures for resolving the displacement problem induced by climate change considering the socioeconomic differences between the past and the present location of living places for island dwellers of the south-eastern coast of Bangladesh.

Both qualitative and quantitative approaches were adopted for conducting the study. The main tool of the household survey was a questionnaire survey. In addition to the estimate of displacement, the authors have used hazard impact analysis, weightage analysis and sustainable adaptation analysis with various ranking. Meaningful data were analyzed through SPSS software and presented through statistical techniques.

Climate change-induced different natural disasters, such as cyclone, tidal surge, tidal flood and coastal erosion, were frequent in the study areas and responsible for mass displacement. After displacement, people lost not only their identity but also social and cultural harmony and faced different economic and environmental crises. However, nearly 20 types of adaptation options were identified for protection from the displacement of coastal people.

The study prescribed 11 specific criteria and 4 principles of sustainable adaptation options for resolving the climate displacement problem. Moreover, seven adaptation practices showed high sustainability, ten showed medium sustainability and five showed low sustainability in terms of effectiveness, efficiency and implementation ability.

The study would help to establish sustainable adaptation measures through the combination of environment, economic and social harmony with regard to the Sustainable Development Goals.

The purpose of this paper is to assess the extent to which Mauritius has structured its adaptation to and mitigation of the climate change and its effects on the tourism industry based on the UNEP framework on tourism and climate change.

The UNEP framework is used as a guideline based on which an assessment of the various policies, laws or regulations existent in Mauritius is carried out.

The paper highlights the significant lacunas that exist in Mauritius with regard to this subject matter with measures taken in good faith but not structured and oriented enough to meet long-term goals.

This paper adds to the meagre literature that exists in Mauritius on the legal or normative framework that exists in Mauritius concerning climate change and the tourism industry.

This paper aims to understand the perception of smallholder farmers on climate change, identify major livestock related climate change adaptation (CCA) strategies and their determinants in selected neighboring districts of Tigray and Amhara regions of Ethiopia.

A total of 416 household heads were involved in a questionnaire survey using a multistage sampling approach. To understand the socio-economic factors that influence farmers’ perception on climate change (CC) and/or variability, a binary logit model was used. Multinomial logit model was used to identify the determinants of smallholder farmers’ choices of adaptation strategies.

Milk reduction, weight loss, feed shortage and frequent animal disease outbreak were indicated as major impacts of CC on livestock production. About 86.2% of the farmers’ exercise CCA measures where livestock health care and management (25%), followed by livelihood diversification (21.5%) and shifting and diversification of livestock species (20.9%) were the top three adaptation measures implemented. Education, knowledge on CCA strategies, access to veterinary service and extension, market access, annual income, non-farm income, total livestock unit, sex of household head and household size were the major determinant factors to farmers’ choice of CCA.

Concerned authorities working in CC related sectors should give due attention to improve smallholder farmers’ access to extension and veterinary services, market access and climate information to enhance their adaptive capacity to CC impacts. In addition, incorporating climate change awareness trainings into the existing extension packages is crucial to enhance the awareness of farmers on climate change and implement appropriate adaptation strategies. Moreover, it is very essential to provide appropriate herd management and marketing strategy based on the production system to avoid the significant price reduction during drought periods.
