A preliminary discussion on the opportunities and challenges of linking climate change adaptation with disaster risk reduction

Managing the risks of extreme events such as natural disasters to advance climate change adaptation (CCA) has been a global focus. However, a critical challenge in supporting CCA is to improve its linkage with disaster risk reduction (DRR). Based on discussions on similarities and differences between CCA and DRR concerning their spatial–temporal scales, main focuses, preferred research approaches and methodologies, etc., this paper tentatively put forward an analytical framework of “6W” for linking DRR with CCA. This framework presented preliminary answers to a series of fundamental questions, such as “What is adaptation with respect to disaster risk?” “Why adaptation is needed?” “Who adapt to what?” “How to adapt?” “What are the possible principles to assess the adaptation effect?” To bridge the research gaps between CCA and DRR, it is imperative to associate the adaptation actions with both near-term disaster risk and long-term climate change and formulate adaptation strategies at various spatial–temporal scales by embracing uncertainty in a changing climate.     

Farmers’ assessments of private adaptive measures to climate change and influential factors: a study in the Mekong Delta,Vietnam

Adaptation to climate change in agricultural settings depends on understanding farmers’ perceptions of the nature of climate change, their agency in adapting and the efficacy of adaptive measures themselves. Such knowledge can improve mitigation and adaptation strategies. This study addresses the limited understanding of how farmers appraise their private adaptive measures and influential factors. It uses data from structured interviews with 598 rice farmers in the Mekong Delta, Vietnam. Based on protection motivation theory, farmers’ assessments of private adaptive measures were measured by perceived self-efficacy, perceived adaptation efficacy and perceived adaptation cost. Multiple regressions were used to understand significant factors affecting those assessments. Some demographic and socio-economic factors, belief in climate change, information and objective resources were found to influence farmers’ adaptation assessments. It is shown that the sources and quality of information are particularly important. The improvement of both the accessibility and usefulness of local services (e.g. irrigation, agricultural extension, credit and health care) is deemed a necessity for successful adaptation strategies in the Mekong Delta. The paper also shows the application of PMT in measuring farmers’ appraisals of private adaptive measures to climate change, thereby opening this area for further research.     

Climate change and its effects on urban spaces in Chile: A summary of research carried out in the period 2000-2012

We have systematized the effects associated with climate change on urban spaces in Chile reported between 2000 and 2012. The method was based on a review of scientific articles in three databases (Scopus, Web of Knowledge and Scielo) using 32 keywords. Only 14 research papers were found related to climate change in urban spaces, most of which were case studies focused on the capital, Santiago. The main effects on urban spaces were found in four areas: (1) increase in temperature (heat islands, heat waves), (2) health problems in vulnerable populations (cardiac complications, heat stroke, and respiratory diseases), (3) increased demand for water, and (4) damage to the urban infrastructure with resulting risk to the population. In these circumstances the following measures are needed: (1) effective incorporation of the potential impacts of climate change into territorial planning instruments, (2) increased green areas to mitigate the impact of heat waves, (3) limiting of housing or public services in areas at risk, (4) encouraging the design of adaptation plans by involving the vulnerable population, and (5) implementing water conservation measures. We conclude that climate change is causing effects in urban areas that should be considered in the design and expansion of cities.     

Climate change and the resilient society: utopia or realistic option for German regions?

For the last five years, climate change has been increasingly perceived as a challenge for regional development. Compared to other nations, Germany is relatively ‘safe’, but the German regions are prone to different impacts of climate change; some of them might be positive but most will be negative in the long run. Strategic concepts are therefore needed to reduce the negative impacts and use the potential positive effects. Due to enforced research funding, several German regions are currently developing adaptation strategies within transdisciplinary research projects. Based on a comparative case study analysis of three of these projects, this paper looks for the benefits of resilience thinking in the context of climate change adaptation. The analysis shows that the case study regions try to increase their resilience to climate change by strengthening the properties of (1) resistance, (2) recovery and (3) creativity. But the discussion also reveals that only parts, certain sectors or subjects, of the region can increase their distinct resilience. Regional stakeholder networks as established within the case study regions can make a significant contribution to linking different sectors and levels of action. Therefore, this approach seems to be applicable for integrating the need for adaptation within the whole region. It is believed that the regionalized communication of potential climate change impacts raises awareness for climate change adaptation, helps to develop appropriate adaptation measures and encourages action. Hence, different approaches can indeed lead to more resilient structures. But the resilient society at regional level remains utopia.

Micro-level perception to climate change and adaptation issues: A prelude to mainstreaming climate adaptation into developmental landscape in India

Climate change adds another dimension of challenges to the growth and sustainability of Indian agriculture. The growing exposure to livelihood shocks from climate variability/change and limited resource base of the rural community to adapt has reinforced the need to mainstream climate adaptation planning into developmental landscape. However, a better understanding of micro-level perceptions is imperative for effective and informed planning at the macro-level. In this paper, the grass-root level perspectives on climate change impacts and adaptation decisions were elicited at farm level in the Moga district of Punjab and Mahbubnagar district of Telangana, India. The farmers opined that the climatic variability impacts more than the long-term climate change. They observed change in the quantum, onset and distribution of rainfall, rise in minimum as well as maximum temperature levels, decline in crop yield and ground water depletion. The key socio-economic effects of climate change included decline in farm income, farm unemployment, rural migration and increased indebtedness among farmers. In order to cope with climate variability and change thereon, farmers resorted to adaptation strategies such as use of crop varieties of suitable duration, water conservation techniques, crop insurance and participation in non-farm activities and employment guarantee schemes. Farmers’ adaptation to changing climate was constrained by several technological, socio-economic and institutional barriers. These include limited knowledge on the costs–benefits of adaptation, lack of access to and knowledge of adaptation technologies, lack of financial resources and limited information on weather. Besides, lack of access to input markets, inadequate farm labour and smaller farm size were the other constraints. Further, on the basis of the grass-root elicitation a ‘Need-Based Adaptation’ planning incorporating farmers’ perceptions on climate change impacts, constraints in the adoption of adaptation strategies and plausible adaptation options were linked with the most suitable ongoing programmatic interventions of the Government of India. The study concluded that micro-level needs and constraints for various adaptation strategies and interventions should be an integral part of the programme development, implementation and evaluation in the entire developmental paradigm.     

Evaluating climate change adaptation efforts on the US 50 states’ hazard mitigation plans

Climate change brings uncertain risks of climate-related natural hazards. The US Federal Emergency Management Agency (FEMA in Climate change: long-term trends and their implications for emergency management, 2011. https://www.fema.gov/pdf/about/programs/oppa/climate_change_paper.pdf) has issued a policy directive to integrate climate change adaptation actions into hazard mitigation programs, policies, and plans. However, to date there has been no comprehensive empirical study to examine the extent to which climate change issues are integrated into state hazard mitigation plans (SHMPs). This study develops 18 indicators to examine the extent of climate change considerations in the 50 SHMPs. The results demonstrate that these SHMPs treat climate change issues in an uneven fashion, with large variations present among the 50 states. The overall plan quality for climate change considerations was sustained at an intermediate level with regard to climate change-related awareness, analysis, and actions. The findings confirm that climate change concepts and historic extreme events have been well recognized by the majority of SHMPs. Even though they are not specific to climate change, mitigation and adaptation strategies that can help reduce climate change risks have been adopted in these plans. However, the plans still lack a detailed assessment of climate change and more incentives for collaboration strategies beyond working with emergency management agencies.     

We are not all the same!: Comparative climate change vulnerabilities among fishers in Old Harbour Bay,Jamaica

There is a general consensus that Small Island Developing States are among the most vulnerable to experience climate injustices. Vulnerability studies of climate change effects on communities have often focused on differences between communities given these climate injustices. However, there is a need to also focus on vulnerability within communities, referred to here as comparative vulnerabilities. Climate justice therefore becomes even more important with more focused attention given to the nuances within groups that fall within the vulnerable category. This article examines comparative vulnerabilities for the fishing community in Jamaica. A survey of 241 fishers from Old Harbour Bay, the largest fishing village in Jamaica, was conducted to examine the level of vulnerability of different fishers to climate change. A vulnerability index was constructed for the community and then comparative vulnerabilities were determined based on socio-demographic characteristics. Overall for the sample 46.9% of respondents would be considered as experiencing a comparatively high level of vulnerability to climate change. Climate change vulnerability was influenced by a number of socio-demographic variables with unique profiles emerging for groups that can be ranked as low, moderate, and high vulnerability. The paper therefore argues that within vulnerable populations there are comparative vulnerabilities based on economic factors and social capital, which must be taken into consideration for adaptation strategies to be implemented. Given these comparative vulnerabilities a more targeted approach to coping and adaptation strategies can then be taken. This will assist in building resilience of these communities that must now adjust to a new normal with climate change effects currently occurring.     

Climate variability/change and attitude to adaptation technologies: a pilot study among selected rural farmers’ communities in Nigeria

Understanding climate variability and change is essential for designing adaptation policies and strategies to deal with the impacts of climate change on the agricultural sector. This Paper aims at assessing climate variability/change, the perception of rural farmers on climate change and preferred  adaptation strategies among the farmers in some selected farming communities in Nigeria. The study thus used both meteorology data and social survey, to examine variability/change in climate and factors determining the adaptation techniques adopts by rural farmers. The results show a relatively uniform temperatures and some seasonal variations in recent years (diurnal range of temperature is about 10 °C) but the rainfall shows much more seasonal variations. The rainfall has relatively undeviating trend from 1981 to 1996 but the trend appears to be upwards from the year 1997 to 2010. About 72.8% participants responded in the affirmative that climate is changing but there appears to be a significant relationship between the length of farming experiences and farmers’ perceptions of climate change adaptation techniques. Water-related (about 53%) and nutrient related (about 52%) technologies appear to have a high preference among the farmers. The major driver that determines farmers’ preference for climate change adaptation techniques is their incomes and experiences.     

Climate Change and Human Health: Risk Assessments,Early Signals and Response Strategies

Climate change is considered as the biggest global health threat of the 21^st century. The increasing adverse health effects of climate change has been a public concern worldwide. In order to develop the specific health response strategies, a key research project, "Climate change and human health: Risk assessments, early signals and response strategies", was approved by the National Key R & D Program of China in May 2018. This project will integrate researchers from multidisciplinary background, such as public health, medicine, meteorological sciences, disaster management, to address the following scientific questions: ①The impact of climate change on population health and its regional heterogeneity; ②The underlying mechanisms and pathways of how climate change and extreme events impact on health; ③Capture of the early signals of climate system anomalies which may lead to regional health risks; ④The comprehensive health risk assessments and development of coping strategies for tackling climate change. This project will improve our understanding of climate change and health and help policy maker to develop national and local responses to climate change in China.     

Estimations of climate change impacts on crop production in the Republic of Moldova

Statistical methods for assessing crop sensitivity and vulnerability to climate change in Moldova were demonstrated and the following procedures were discussed: (1) projections of likely agroclimatic change; (2) assessments of crop sensitivity to climate change; and (3) assessments of the impact of climate change on crops. In order to predict the future agroclimate, key meteorological variables were transformed statistically to correspond to changes in plants' heat and water supply characteristics. Sensitivity of crop production was examined for corn and winter wheat. By combining the agroclimatic changes with crop response, possible impacts have been estimated and form a basis for possible adaptation strategies. It was shown that regional climate change can result in elevated aridity of Moldova's territory, especially during periods of crop growth. Cultivation of cereal crops in new agroclimatic conditions without adaptation measures will negatively affect yields, especially of winter wheat, whose yield decrease may be 18–39% by 2020s and 22–50% by 2050s. Corn yields may increase by 0–3% and 1–6%, respectively. As an example of adaptation, it is shown that the use of an increased number of late hybrids results in a 25–35% increase in corn yields. This revised version was published online in July 2006 with corrections to the Cover Date.

Climate change and increased risk for the insurance sector: a global perspective and an assessment for the Netherlands

Climate change is projected to increase the frequency and severity of extreme weather events. As a consequence, economic losses caused by natural catastrophes could increase significantly. This will have considerable consequences for the insurance sector. On the one hand, increased risk from weather extremes requires assessing expected changes in damage and including adequate climate change projections in risk management. On the other hand, climate change can also bring new business opportunities for insurers. This paper gives an overview of the consequences of climate change for the insurance sector and discusses several strategies to cope with and adapt to increased risks. The particular focus is on the Dutch insurance sector, as the Netherlands is extremely vulnerable to climate change, especially with regard to extreme precipitation and flooding. Current risk sharing arrangements for weather risks are examined while potential new business opportunities, adaptation strategies, and public–private partnerships are identified.     

Déjà vu or something new? The adaptation concept in the climate change literature

This paper reflects on the resurgence and meaning of the adaptation concept in the current climate change literature. We explore the extent to which the early political economic critique of the adaptation concept has influenced how it is used in this literature. That is, has the current conceptualization been enriched by the political economic critique of the 1970s and 1980s and thus represent something new? Or is the concept used in a way today that echoes previous debates; that is, is this a déjà vu experience? To answer this question, we review the early political economic critique of the natural hazards school’s interpretations of vulnerability and adaptation. We then examine the revival of the adaptation concept in the climate change literature and discuss its main interpretations. For the purposes of this paper, the climate change literature encompasses the four IPCC reports and adaptation-focused articles in four scholarly journals: Global Environmental Change, Climatic Change, Climate and Development, and Mitigation and Adaptation Strategies for Global Change. Our content analysis shows the dominance (70%) of “adjustment adaptation” approaches, which view climate impacts as the main source of vulnerability. A much smaller percentage (3%) of articles focus on the social roots of vulnerability and the necessity for political–economic change to achieve “transformative adaptation.” A larger share (27%) locates risk in both society and the biophysical hazard. It promotes “reformist adaptation,” typically through “development,” to reduce vulnerability within the prevailing system. We conclude with a discussion of continuity and change in the conceptualization of adaptation, and point to new research directions.

Uneven socio-ecologies of Hispaniola: Asymmetric capabilities for climate adaptation in Haiti and the Dominican Republic

This article adopts a “capabilities” approach to climate justice to examine a globally unique phenomenon: a decade of unprecedented surface area growth in Lake Azuéi (the largest lake in Haiti) and Lake Enriquillo in the Dominican Republic (the largest lake in the Caribbean region). The objective was to explore how two neighbouring communities and their governments respond to large-scale environmental change within connected but uneven political ecological contexts. Current climate change impacts in this bi-national island present an opportunity to better understand not only local climate justice but also how fragmented sovereignty, territoriality, and citizenship regimes may affect processes of climate adaptation. The researchers conducted 27 semi-structured interviews in the Dominican Republic and 11 in Haiti, with open ended questions. The data analysis explores impacts of the lakes’ growth; perceived causes and solutions; access to assistance; views on responsibility; and capacities for mobilization, bi-national cooperation, and international partnerships. The article argues that different capabilities for climate adaptation are shaped by historical path dependencies, local institutional contexts, and international linkages; and that attaining climate justice requires attention to these factors within a collective normative framework. The conclusion examines how climate science, research partnerships, and citizen participation might be leveraged to help build binational adaptation strategies grounded in a capabilities approach to climate justice.     

National vulnerability to extreme climatic events: the cases of electricity disruption in China and Japan

Extreme climatic events are likely to adversely affect many countries throughout the world, but the degrees among countries may be different. China and Japan are the countries with high incidences of extreme weather/disaster, both facing with the urgent task of addressing climate change. This study seeks to quantitatively compare the impacts of extreme climatic events on socioeconomic systems (defined as vulnerability) of the two countries by simulating the consequences of hypothetical same degree of electricity disruption along with extreme events. To do that, two computable general equilibrium models are constructed, by using which three-stage scenarios are simulated for China and Japan, respectively. The results reveal that China and Japan have unequal socioeconomic vulnerabilities to extreme events. (1) Negative impact of the same degree of power outages is bigger on China’s socioeconomic system than on that of Japan, and this difference is more obvious in the very short-run scenario. (2) The decline of China’s GDP, total output, and employment levels is 2–3 times higher than that of Japan, while the difference of the resident welfare levels is sharper, which of China drops 3–5 times of Japan. (3) Structural factors are the main reason for vulnerability differences between China and Japan, including the differences of expenditure structure, factor input structure for production of life requirement sectors, material and energy dependence for the production of industrial sectors, and usage structure of services outputs. Based on these findings, some policy implications and recommendations for fairness issues on climate change adaptation are proposed.

Anticipatory Adaptation Approaches to Climate Change--A Review and Discussion of Southern Australia’s Sustainable Water Management and Its Strategies and Shortcomings

Climate change issues has been discussed and argued for decades. It has been widely recognized that climate change will bring more serious issues to environment vulnerable areas than other areas. Southern Australia is one of the typical examples of vulnerable areas where water deficiency is enhanced by climate change. Although, this area has been successfully adapted with drought environment for decades, those shortcomings of strategies are highlighted by climate change events. In the interests of sustainable water management, Southern Australia’s experiences on possible anticipatory adaptation approaches, especially on mitigation of risks and costs of drought could be expected to provide recommendations to planning and management actions in the future     

An Environmental Risk Assessment/Management Framework for Climate Change Impact Assessments

This paper presents an environmental risk assessment/risk management framework to assess the impacts of climate change on individual exposure units identified as potentially vulnerable to climate change. This framework is designed specifically to manage the systematic uncertainties that accompany the propagation of climate change scenarios through a sequence of biophysical and socio-economic climate impacts. Risk analysis methods consistent with the IPCC Technical Guidelines for Assessing Climate Change Impacts and Adaptations are set within a larger framework that involves stakeholders in the identification, assessment and implementation of adaptation measures. Extensive consultation between parties occurs in a flexible structure that embeds scientific methods of risk analysis within a broad setting of social decision-making. This format is consistent with recent forms of environmental risk assessment/management frameworks. The risk analysis links key climatic variables expressed as projected ranges of climate change with an upper and lower limit, with impact thresholds identified collaboratively by researchers and stakeholders. The conditional probabilities of exceeding these thresholds are then assessed (probabilities using this method are conditional as the full range of uncertainty for the various drivers of climate change, and their probability distributions, remains unknown). An example based on exceeding irrigation demand limited by an annual farm cap is used to show how conditional probabilities for the exceedance of a critical threshold can be used to assess the need for adaptation. The time between the identification of an acceptable level of risk and its exceedance is identified as a window of adaptation.The treatment of risk consists of two complementary actions, adaptation to anticipated changes in climate and the mitigation of climate change through reductions in greenhouse gas emissions. Both of these actions will reduce the risk of critical thresholds being exceeded. The potential of this framework for addressing specific requirements of the United Nations Framework Convention for Climate Change is discussed.
