Integrating regional perceptions into climate change adaptation: a transdisciplinary case study from Germany’s North Sea Coast

Coastal protection strategies increasingly have to take into account the effects of climate change. At present, engineering and natural science models that assess the impact of global climatic transformations on regional coastal zones and their protection structures remain rather detached from the knowledge and insights of regional practitioners. The main thesis of this contribution, using a case study from the North Sea Coast of Germany, is that innovative coastal protection requires not only interdisciplinary research but transdisciplinary collaboration in order to develop a viable adaptation strategy. The investigation of the social dimension of climate change and coastal protection strategies, using qualitative interviews with organized regional stakeholders, climate researchers and coastal engineers, as well as a representative public survey, contributes to a comprehensive understanding of regional perceptions with respect to climate change and coastal protection.     

Adaptation to climate change as resilience for urban extreme poor: lessons learned from targeted asset transfers programmes in Dhaka city of Bangladesh

This paper aims to identify how targeted asset transfers help to build adaptive capacity and adaptive actions of the urban extreme poor to climate change phenomena. This paper explores the theoretical debates of community-based adaptation approach and failure of such approach to address urban extreme poor. The empirical evidence of these theoretical debates will be drawn from two informal settlements of Dhaka city, where a targeted asset transfer project has been implementing since 2009. This paper explains that urban extreme poor usually work as unskilled labour and lack different livelihood capitals; and climate change is an increasingly important influence exacerbating an already vulnerable livelihood context. There is growing recognition in the literature that poor urban people and communities are adapting to climate change in physical and behavioural terms. But, in the case of urban extreme poor these adaptation approaches are delivering short-term survival strategies disregarding the notion of wellbeing in the medium to long-term perspectives. It is also evident that community level initiatives structurally reproduce the exclusion of the urban extreme poor. However, poverty literatures acknowledge that poverty-centred approaches could help to reduce vulnerability. As urban extreme poor are significantly more resource constrained, it is reasonable to assert that targeted asset transfers could be a poverty-centred adaptation approach in a changing climate. Targeted asset transfers approaches are the outcomes of recent social protection revolution that especially consider accumulation of physical, financial, human, and social capital in order to build adaptive capacity of the urban extreme poor. This adaptive capacity of the extreme poor may facilitate adjustments in assets, livelihoods, behaviours, and technologies in order to reduce future climate vulnerability. In this context, this paper seeks to answer whether targeted asset transfer approaches can be considered as effective poverty-centred adaptation approaches for the urban extreme poor or not.     

The implications of rural perceptions of water scarcity on differential adaptation behaviour in Rajasthan,India

Water scarcity is one of the most critical issues facing agriculture today. To understand how people manage the risk of water scarcity and growing pressures of increased climate variability, exploring perceptions of risk and how these perceptions feed into response behaviour and willingness to adapt is critical. This paper revisits existing frameworks that conceptualise perceptions of environmental risk and decision-making, and uses empirical evidence from an in-depth study conducted in Rajasthan, India, to emphasise how individual and collective memories, and experience of past extreme events shape current definitions and future expectations of climatic risks. In doing so, we demonstrate the value of recognising the role of local perceptions of water scarcity (and how they vary between and within households) in constructing social vulnerability. This expanded understanding of risk perception is critical for incentivising individual adaptation and strengthening local adaptation pathways.     

Climate capacity:the measurement for adaptation to climate change

This article proposed the concept of"climate capacity"as a way of measuring human’s adaptiveness to climate change.This article also focused on the related concepts like ecological carrying capacity,water resources carrying capacity,land carrying capacity as well as population carrying capacity.The concept of climate capacity was articulated against a background of global climate and environmental change.Essentially,China’s efforts to adapt to climate change was a matter of improving climate capacity,which is the ecosystem as well as the frequency,the intensity and the scale of human’s social activities that the climatic resources of a particular geographic area were supposed to support.The climate capacity has two components.One is the natural climate capacity,which includes temperature,sunlight,precipitation,extreme climatic events,etc.The other is the derived climate capacity,which includes water resources,land resources,ecological systems,climatic risks,etc.The climate capacity can be developed or be transferred between regions by taking engineering,technology or regime-based adaptive measures.However,these adaptive measures must be implemented under the principle of economic rationalism,ecological integrity,climate protection,and social justice.It is expected that by combining the climate capacity and its threshold value with the assessment of climate change risks,we are able to predict the optimal population carrying capacity and the scale of socioeconomic development,and furthermore,provide policy support for the socioeconomic development strategy and adaptive planning.In the regions with high climate capacity,there is a symbiotic relationship between adaptation and socioeconomic development.But,in the regions with limited climate capacity,irrational development may further damage the environment.Taking the Yangtze River delta,a region with high climate capacity,and a region of Ningxia,a region with limited climate capacity,as illustrative examples,the authors of this article analyzed the policy implications of climate capacity and further made suggestions on the problems of capacitylimited adaptation and development-driven adaptation.This article argued that the concept of climate capacity can not only be used as an analytical instrument of climate change economics,but also it can provide research support for planning regional adaptation and development with climate change impact and risk assessments.     

Climate change/variability and food systems: evidence from the Afram Plains,Ghana

While there are many studies of the impacts of climate change and variability on food production, few studies are devoted to a comprehensive assessment of impacts on food systems. Results of a survey of food systems and household adaptation strategies in three communities in the Afram Plains, Ghana, reveal how extreme climatic events affect rural food production, transportation, processing and storage. Adaptation strategies implemented by the three communities during past droughts serve as a foundation for planning responses to future climate change. Results of this study suggest that food security in this region—where droughts and floods are expected to become more severe due to climate change—could be enhanced by increasing farm-based storage facilities; improving the transportation system, especially feeder roads that link food production areas and major markets; providing farmers with early warning systems; extending credit to farmers; and the use of supplementary irrigation. This study also indicates that some cultural practices, particularly those that prohibit the consumption of certain foods, may reduce the resilience of some individuals and ethnic groups to food system disruptions. Understanding the local context and the responses of households is critical to the development of effective strategies for reducing the potential adverse impacts of climatic change on food security in rural Ghana.     

Community-based scenario planning: a process for vulnerability analysis and adaptation planning to social–ecological change in coastal communities

The current and projected impacts of climate change make understanding the environmental and social vulnerability of coastal communities and the planning of adaptations important international goals and national policy initiatives. Yet, coastal communities are concurrently experiencing numerous other social, political, economic, demographic and environmental changes or stressors that also need to be considered and planned for simultaneously to maintain social and environmental sustainability. There are a number of methods and processes that have been used to study vulnerability and identify adaptive response strategies. This paper describes the stages, methods and results of a modified community-based scenario planning process that was used for vulnerability analysis and adaptation planning within the context of multiple interacting stressors in two coastal fishing communities in Thailand. The four stages of community-based scenario planning included: (1) identifying the problem and purpose of scenario planning; (2) exploring the system and types of change; (3) generating possible future scenarios; and (4) proposing and prioritizing adaptations. Results revealed local perspectives on social and environmental change, participant visions for their local community and the environment, and potential actions that will help communities to adapt to the changes that are occurring. Community-based scenario planning proved to have significant potential as an anticipatory action research process for incorporating multiple stressors into vulnerability analysis and adaptation planning. This paper reflects on the process and outcomes to provide insights and suggest changes for future applications of community-based scenario planning that will lead to more effective learning, innovation and action in communities and related social–ecological systems.     

Variation in perception of environmental change in nine Solomon Islands communities: implications for securing fairness in community-based adaptation

Community-based approaches are pursued in recognition of the need for place-based responses to environmental change that integrate local understandings of risk and vulnerability. Yet the potential for fair adaptation is intimately linked to how variations in perceptions of environmental change and risk are treated. There is, however, little empirical evidence of the extent and nature of variations in risk perception in and between multiple community settings. Here, we rely on data from 231 semi-structured interviews conducted in nine communities in Western Province, Solomon Islands, to statistically model different perceptions of risk and change within and between communities. Overall, people were found to be less likely to perceive environmental changes in the marine environment than they were for terrestrial systems. The distance to the nearest market town (which may be a proxy for exposure to commercial logging and degree of involvement with the market economy), and gender had the greatest overall statistical effects on perceptions of risk. Yet, we also find that significant environmental change is underreported in communities, while variations in perception are not always easily related to commonly assumed fault lines of vulnerability. The findings suggest that there is an urgent need for methods that engage with the drivers of perceptions as part of community-based approaches. In particular, it is important to explicitly account for place, complexity and diversity of environmental risk perceptions, and we reinforce calls to engage seriously with underlying questions of power, culture, identity and practice that influence adaptive capacity and risk perception.

     

Adapting cropping systems to climate change in Nepal: a cross-regional study of farmers’ perception and practices

Climate change is a global challenge that has a particularly strong effect on developing countries such as Nepal, where adaptive capacity is low and where agriculture, which is highly dependent on climatic factors, is the main source of income for the majority of people. The nature and extent of the effects of climate change on rural livelihoods varies across Nepal in accordance with its highly diverse environmental conditions. In order to capture some of this variability, a comparative study was performed in two different ecological regions: Terai (lowland) and Mountain (upland) in the western development region of Nepal. The study focuses on perceptions of, and on adaptations to climate change by farmers. Information was collected from both primary and secondary data sources. Climate data were analyzed through trend analysis. Results show that most farmers perceive climate change acutely and respond to it, based on their own indigenous knowledge and experiences, through both agricultural and non-agricultural adaptations at an individual level. The study also shows that there is a need to go beyond the individual level, and to plan and provide support for appropriate technologies and strategies in order to cope with the expected increasing impacts of climate change.     

Perceptions of climate change risk in four disaster-impacted rural Australian towns

Australia, a country which has regularly experienced various natural disasters, is now set to face more intense and frequent disasters in the twenty-first century as a result of climate change. Prior research indicates that in Australia, the perceived risks of climate change are mixed and becoming less prevalent across rural and urban locations, posing a threat to the public’s adoption of mitigation and adaptation strategies. Research was conducted in four disaster-impacted rural Australian towns to investigate whether prior disaster experience, trust in climate change risk communications and specific location predicted climate change risk perceptions. Four case study sites were chosen exemplifying communities impacted by different types of disaster events. The case study towns were Beechworth (wildfire, 2009) and Bendigo (drought, 2002–2008) in Victoria; Ingham (flood, 2009) and Innisfail (cyclone, 2006) in Queensland. Structural equation modelling analyses of surveys returned by a sample of 1,008 householders across the four towns showed that prior disaster experience had no impact upon climate change risk perceptions. Instead climate change risk perceptions were predicted by trust in climate change communications, climate change knowledge and the geographical location of the sample, suggesting the need for targeted, place-specific contextual communication interventions that consider the needs and socioeconomic characteristics of the community in question.

Social capital and citizen perceptions of coastal management for tackling climate change impacts in Greece

There is a growing consensus among researchers that social aspects and the involvement of local communities play a critical role in public decision-making processes in the coastal zone. Social capital is a parameter which has recently gained significant attention in this context. It is regarded that it has a significant influence on the adaptation capacity of local communities to climate change impacts. The present paper aims to contribute to this field through an examination of citizens’ perceptions of three coastal zone management policies (hold the line, managed realignment and no active intervention) along with the influence of social capital on the level of social acceptability for these proposed policy options. For this purpose, a quantitative empirical study was conducted for the first time in five coastal areas of Greece that are regarded as high flood-risk areas due to sea-level rise. Respondents demonstrated that they are willing to accept changes in their social and natural environments in order to confront sea-level rise and are more positive towards the managed realignment option, as long as this is accompanied by financial compensation for those whose properties will be affected. Regarding the influence of social capital, through the results of an ordinal regression, it was observed that institutional and social trust influence positively citizens’ level of agreement for the managed realignment policy. Furthermore, respondents who believe that a sense of reciprocity exists in their community are also more willing to accept active intervention policies.     

Perceived stressors of climate vulnerability across scales in the Savannah zone of Ghana: a participatory approach

Smallholder farmers in sub-Saharan Africa are confronted with climatic and non-climatic stressors. Research attention has focused on climatic stressors, such as rainfall variability, with few empirical studies exploring non-climatic stressors and how these interact with climatic stressors at multiple scales to affect food security and livelihoods. This focus on climatic factors restricts understanding of the combinations of stressors that exacerbate the vulnerability of farming households and hampers the development of holistic climate change adaptation policies. This study addresses this particular research gap by adopting a multi-scale approach to understand how climatic and non-climatic stressors vary, and interact, across three spatial scales (household, community and district levels) to influence livelihood vulnerability of smallholder farming households in the Savannah zone of northern Ghana. This study across three case study villages utilises a series of participatory tools including semi-structured interviews, key informant interviews and focus group discussions. The incidence, importance, severity and overall risk indices for stressors are calculated at the household, community, and district levels. Results show that climatic and non-climatic stressors were perceived differently; yet, there were a number of common stressors including lack of money, high cost of farm inputs, erratic rainfall, cattle destruction of crops, limited access to markets and lack of agricultural equipment that crossed all scales. Results indicate that the gender of respondents influenced the perception and severity assessment of stressors on rural livelihoods at the community level. Findings suggest a mismatch between local and district level priorities that have implications for policy and development of agricultural and related livelihoods in rural communities. Ghana’s climate change adaptation policies need to take a more holistic approach that integrates both climatic and non-climatic factors to ensure policy coherence between national climate adaptation plans and District development plans.     

The Gathering Storm: managing adaptation to environmental change in coastal communities and small islands

Small island communities are inherently coastal communities, sharing many of the attributes and challenges faced by cities, towns and villages situated on the shores of larger islands and continents. In the context of rapidly changing climates, all coastal communities are challenged by their exposure to changing sea levels, to increasingly frequent and severe storms, and to the cumulative effects of higher storm surges. Across the globe, small island developing states, and small islands in larger states, are part of a distinctive set of stakeholders threatened, not only by climate change but also by shifting social, economic, and cultural conditions. C-Change is a collaborative International Community–University Research Alliance (ICURA) project whose goal is to assist participating coastal communities in Canada and the Caribbean region to share experiences and tools that aid adaptation to changes in their physical environment, including sea-level rise and the increasing frequency of extreme weather events associated with climate change. C-Change researchers have been working with eight partner communities to identify threats, vulnerabilities, and risks, to improve understanding of the ramifications of climate change to local conditions and local assets, and to increase capacity for planning for adaptation to their changing world. This paper reports on the knowledge gained and shared and the challenges to date in this ongoing collaboration between science and society.     

Land-users’ perceptions and adaptations to climate change in Mexico and Spain: commonalities across cultural and geographical contexts

Comparing agricultural management practices across scales and in different cultural settings can reveal shared insights into the capacity to adjust and respond to change and uncertainty. Differences make comparisons in environmental risk perceptions and responses particularly interesting and valuable, with obtained similarities being in many ways more interesting than found differences, which might be readily expected in places with remarkable geographical and demographic differences. People’s perception of climatic risks and hazards appears to be important to understand the context in which adaptation strategies to climate change emerge. Our intention, rather than compare the two case studies at the local scale, one in Mexico and one in Spain, is to identify existing common mechanisms to perceive climate change and to address adaptation among two very different geographical and cultural contexts. The study aims first to explore people’s perceptions of climate change and its outcomes; second to analyse the adaptation measures that they have developed and develop some preliminary ideas about their strategies; and third to consider the capacity of people to cope and adapt endogenously, in terms of the measures that people think that their governments should take to enhance/strengthen them at the local scale.     

Climate change perceptions and adaptations of smallholder farmers in Eastern Kenya

Several studies have indicated the importance of understanding farmers’ perceptions of risks associated with climate change, the adaptation strategies they employ and factors that affect adaptive capacity. This study aimed to understand smallholder farmers’ perceptions of climate change, adaptation strategies and adaptive capacity in the semiarid Matungulu Sub-County, Eastern Kenya. A participatory approach, using three climate roundtables, was conducted to enhance community participation and understanding of climate change issues. The study showed that farmers’ perceptions concerning climate change are influenced by past experiences of weather extremes that have affected production levels and farm incomes. The farmers have made strategic responses to manage risks posed by climate change. However, they face several challenges in adaptation such as inadequate technical knowledge, low financial resources and inadequate land size. Further, the study showed that climate roundtables is a successful participatory approach that can give effective insights for smallholder farmers to understand agricultural vulnerability, climate change and their adaptation strategies.     

Characterising the nature of household vulnerability to climate variability: empirical evidence from two regions of Ghana

This paper builds on national- and regional-level vulnerability assessments by developing and applying a livelihood vulnerability index at the community and household scales to explore the nature of climate vulnerability. It provides innovative methodological steps in relation to livelihood assessment to identify the vulnerability of households and communities to drought. This will help to improve drought vulnerability assessments in Ghana and more widely as it shows extra information can be obtained from local-level vulnerability assessment that may be lacking in national- and regional-level analysis. The research employs quantitative and qualitative data collected through participatory methods, key informant interviews and a questionnaire survey with 270 households across 6 communities in two regions in Ghana. Results show that within the same agroecological zone, households and communities experience different degrees of climate vulnerability. These differences can be largely explained by socioeconomic characteristics such as wealth and gender, as well as access to capital assets. Results identify vulnerable households within resilient communities as well as more resilient households within vulnerable communities. These outliers are studied in detail. It is found that outlier households in vulnerable communities have an array of alternative livelihood options and tend to be socially well connected, enabling them to take advantage of opportunities associated with environmental and economic changes. To sustain and enhance the livelihoods of vulnerable households and communities, policymakers need to identify and facilitate appropriate interventions that foster asset building, improve institutional capacity as well as build social capital.     

Farmers perception and awareness of climate change: a case study from Kanchandzonga Biosphere Reserve,India

This study was an attempt to document the indigenous Lepcha people’s perception on climate change-related issues in five villages of Dzongu Valley located in Kanchandzonga Biosphere Reserve, India. Personal structured questionnaire was used for interview of 300 households selected randomly. Results showed that 85 % of the households have perceived climate change, mainly in the form of increasing temperature and unpredictable pattern of rainfall. In terms of climate change-related events, 75 % of the households believed that wind is becoming warmer and stronger over the past years. Majority of the households have observed changes in crop phenology, while about 90 % agreed that the incidences of insect pest and diseases have increased over the years, especially in their large cardamom crop. A comparison of community perceptions, climatic observations and scientific literature shows that the community have correctly perceived temperature change, unpredictable occurrence of rainfall and increased incidence of insect pest and diseases, which have largely influenced the experiences and perceptions regarding climate-related events. Results reveal that households have adopted the use of locally available material as mulches against soil erosion, to conserve the soil moisture and manage soil temperature. Majority of the households have diversified their cropping system through traditional agroforestry systems and intercropping. Unfortunately, most of the households were unaware about the scientific sustainable approaches to combating impact of climate change. This documentation will aid in assessing the needs in terms of actions and information for facilitating climate change-related adaptation locally in Sikkim state of India.     

Migration drivers in mountain regions in the context of climate change:A case study in Shangnan County of China

Climate change has become widely accepted as a challenge that humans will face in the not-too-distant future.Mountain ecosystems and their inhabitants are among the most vulnerable to climate change.This paper seeks to explain migration drivers in specific mountain regions in the context of climate change based on Foresight’s conceptual framework.A climate change sensitive field named Shangnan County in southern Shaanxi Province is chosen as the case study area to investigate local migration drivers.A series of qualitative research methods is employed in the case study including participant observation,semi-structured interviews,and focus group discussions.The evidence of survey suggests that migration decisions are not only shaped by macro factors in aspects of environmental,economics,demographic,social,politics and psychological,but also influenced by placed-related barriers and facilitating mechanisms and personal characteristics.     

Livelihood vulnerability approach to assessing climate change impacts on mixed agro-livestock smallholders around the Gandaki River Basin in Nepal

Climate change vulnerability depends upon various factors and differs between places, sectors and communities. People in developing countries whose subsistence livelihood depends mainly upon agriculture and livestock production are identified as particularly vulnerable. Nepal, where the majority of people are in a mixed agro-livestock system, is identified as the world’s fourth most vulnerable country to climate change. However, there is limited knowledge on how vulnerable mixed agro-livestock smallholders are and how their vulnerability differs across different ecological regions in Nepal. This study aims to test two vulnerability assessment indices, livelihood vulnerability index and IPCC vulnerability index, around the Gandaki River Basin of central Nepal. A total of 543 households practicing mixed agro-livestock were surveyed from three districts, namely Dhading, Syangja and Kapilvastu representing three major ecological zones: mountain, mid-hill and Terai (lowland). Data on socio-demographics, livelihood determinants, social networks, health, food and water security, natural disasters and climate variability were collected and combined into the indices. Both indices differed for mixed agro-livestock smallholders across the three districts, with Dhading scoring as the most vulnerable and Syangja the least. Substantial variation across the districts was observed in components, sub-components and three dimensions (exposure, sensitivity and adaptive capacity) of vulnerability. The findings help in designing site-specific intervention strategies to reduce vulnerability of mixed agro-livestock smallholders to climate change.     

Resilience and adaptation to extremes in a changing Himalayan environment

Human communities inhabiting remote and geomorphically fragile high-altitude regions are particularly vulnerable to climate change-related glacial hazards and hydrometeorological extremes. This study presents a strategy for enhancing adaptation and resilience of communities living immediately downstream of two potentially hazardous glacial lakes in the Upper Chenab Basin of the Western Himalaya in India. It uses an interdisciplinary investigative framework, involving ground surveys, participatory mapping, comparison of local perceptions of environmental change and hazards with scientific data, identification of assets and livelihood resources at risk, assessment of existing community-level adaptive capacity and resilience and a brief review of governance issues. In addition to recommending specific actions for securing lives and livelihoods in the study area, the study demonstrates the crucial role of regional ground-level, community-centric assessments in evolving an integrated approach to disaster risk reduction and climate change adaptation for high-altitude environments, particularly in the developing world.
