Mediterranean agriculture under climate change: adaptive capacity, adaptation, and ethics

In the coming decades, the Mediterranean region is expected to experience various climate impacts with negative consequences on agricultural systems and which will cause uneven reductions in agricultural production. By and large, the impacts of climate change on Mediterranean agriculture will be heavier for southern areas of the region. This unbalanced distribution of negative impacts underscores the significance and role of ethics in such a context of analysis. Consequently, the aim of this article is to justify and develop an ethical approach to agricultural adaptation in the Mediterranean and to derive the consequent implications for adaptation policy in the region. In particular, we define an index of adaptive capacity for the agricultural systems of the Mediterranean region on whose basis it is possible to group its different sub-regions, and we provide an overview of the suitable adaptation actions and policies for the sub-regions identified. We then vindicate and put forward an ethical approach to agricultural adaptation, highlighting the implications for the Mediterranean region and the limitations of such an ethical framework. Finally, we emphasize the broader potential of ethics for agricultural adaptation policy.     

Adaptive urban governance: new challenges for the second generation of urban adaptation strategies to climate change

The task of adapting cities to the impacts of climate change is of great importance—urban areas are hotspots of high risk given their concentrations of population and infrastructure; their key roles for larger economic, political and social processes; and their inherent instabilities and vulnerabilities. Yet, the discourse on urban climate change adaptation has only recently gained momentum in the political and scientific arena. This paper reviews the recent climate change adaptation strategies of nine selected cities and analyzes them in terms of overall vision and goals, baseline information used, direct and indirect impacts, proposed structural and non-structural measures, and involvement of formal and informal actors. Against this background, adaptation strategies and challenges in two Vietnamese cities are analyzed in detail, namely Ho Chi Minh City and Can Tho. The paper thereby combines a review of formalized city-scale adaptation strategies with an empirical analysis of actual adaptation measures and constraints at household level. By means of this interlinked and comparative analysis approach, the paper explores the achievements, as well as the shortcomings, in current adaptation approaches, and generates core issues and key questions for future initiatives in the four sub-categories of: (1) knowledge, perspectives, uncertainties and key threats; (2) characteristics of concrete adaptation measures and processes; (3) interactions and conflicts between different strategies and measures; (4) limits of adaptation and tipping points. In conclusion, the paper calls for new forms of adaptive urban governance that go beyond the conventional notions of urban (adaptation) planning. The proposed concept underlines the need for a paradigm shift to move from the dominant focus on the adjustment of physical structures towards the improvement of planning tools and governance processes and structures themselves. It addresses in particular the necessity to link different temporal and spatial scales in adaptation strategies, to acknowledge and to mediate between different types of knowledge (expert and local knowledge), and to achieve improved integration of different types of measures, tools and norm systems (in particular between formal and informal approaches).     

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.     

Accountability in climate change governance and Caribbean SIDS

The good governance of institutions and regimes requires accountability suited to the particular context of each institution and regime. The paper examines the nature of accountability in climate change governance using the Caribbean region as a case study. In doing so, the paper makes two original contributions. First, using insights from the environmental governance literature, it presents a conceptual framework that categorises the types (levels, relationships and mechanisms) of accountability in governance that can be used to test accountability. The accountability framework comprises two levels (internal/external accountability); four relationships (normative, relational, decision and behavioural); and four mechanisms or processes through which accountability can be exercised (certification, monitoring, participation by stakeholders in the overseeing of projects and self-reporting). Second, through an analysis of survey and interview responses from Caribbean climate change experts, it reports on the nature of accountability in climate change governance in the context of Caribbean Small Island Developing States. To do this, first it identifies the actors involved in Caribbean climate governance at the regional and national scales. Then, using the framework, it examines which levels, relationships and processes exist within and between climate governance regional institutions, international partners, government agencies, non-governmental organisations and the private sector for climate change adaptation and mitigation efforts. The paper draws two main conclusions: first, generally actors valued accountability as a good governance norm. Secondly, limited resources and the perception that using the accountability mechanisms will retard policy implementation led to low levels of accountability in practice. Finally, the study examined how accountability can be enhanced in the climate change sector by ensuring that each of the elements of the framework is operationalised for both state and non-state climate change projects.     

An integrated decision-support process for adaptation planning: climate change as impetus for scenario planning in an agricultural region of Canada

The amount of information required to adapt to climate change is vast: downscaled climate projections, information on environmental impact, sectoral performance, external drivers, regional strategies, policies and practices. It can be argued that most of this information is accessible at the community/regional level, and thus, the important challenges to adaptation are not information gaps, but constraints created by fragmented planning decisions and a sector-by-sector basis for financial and human resource allocations. To strategically address this through adaptation planning, we developed and tested a place-based decision-making framework that creates an integrated platform for considering regional and global sectoral drivers in Eastern Ontario, Canada. Using available socioeconomic and biophysical information from regional authorities, alternative future scenarios were used to describe the range of socioeconomic futures and their vulnerabilities to climate change. We found that: (1) integration of diverse sets of available data (rather than narrowly focused sectoral assessments) helped identify shared common objectives (maximizing the long-term environmental, economic, social well-being within the region), (2) a high degree of congruence existed as the key drivers of change, irrespective of sector, (3) exploring the future scenarios highlighted shared regional priorities and helped identify adaptation priorities requiring more integrated regional planning.     

Communicating climate change for adaptation in rural communities: a Pacific study

The academic literature on climate change communications is growing. However, the majority of this literature focuses on the issue of climate change mitigation in a developed country context, and there is little published material regarding communication in a developing country and adaptation context. Similarly, despite community-based approaches to climate change adaptation and disaster risk reduction increasing in the Pacific Islands region, there is very limited guidance on how to effectively communicate climate change in a way that enhances people’s resilience. This paper documents the experiences of organisations, including local and international non-government and faith-based organisations, governments, regional technical organisations and donor agencies in communicating climate change for adaptation in the Pacific region. Three key climate change communication challenges are highlighted and suggestions made for overcoming them based on results from interviews, a focus group discussion and an online forum. Finally, recommendations are made for good practice guidance in climate change communication that is empowering and culturally relevant.     

Leadership within regional climate change adaptation networks: the case of climate adaptation officers in Northern Hesse,Germany

In the climate adaptation literature, leadership tends to be an understudied factor, although it may be crucial for regional adaptation governance. This article shows how leadership can be usefully conceptualized and operationalized within regional governance networks dealing with climate adaptation. It applies an integrative framework inspired by complexity leadership theory, distinguishing several leadership functions to enhance the adaptive capacity of regional networks. We focus on one specific institutional innovation, appointed climate adaptation officers, who seek to connect science and governance practice, and to mainstream climate adaptation. Our question is twofold: What is the potential of climate adaptation officers to advance the adaptation agenda and to what extent did their establishment and working practice mirror the various leadership functions needed to raise the adaptive capacity of the regional network they operated in? The integrative leadership framework structures the analysis of climate adaptation officers forming part of a government-funded project seeking to enhance adaptation to climate variability in the central German region of Northern Hesse. The data consist of interviews with scientists and regional authority employees and project documentation including an evaluation. We find that climate adaptation officers raised awareness for climate adaptation and helped to shape and implement a number of projects within the overall KLIMZUG programme, highlighting impeding and enabling factors. The process of setting up this institutional innovation involved all forms of leadership functions and is an example of vertical mainstreaming. Its operation involved most clearly enabling and connective leadership functions and is an example of horizontal mainstreaming.     

Legitimacy of urban climate change adaptation: a case in Helsinki

While there is general agreement on the necessity for local adaptation, there is a wide range of different understandings of what type of adaptation is seen as legitimate. It is often contested who should actively steer and take part in local adaptation, for which reasons and based on what kind of mandate, and with which methods. Planning theory can serve as a helpful reference point for examining the sources of legitimacy for adaptation in an urban context. From a planning perspective, adaptation is concerned with climate change as one out of many issues planning has to respond to. The layered co-existence of planning paradigms in practice suggests diverse, sometimes contradictory sources of legitimacy for urban planning and—as we claim here—also for climate change adaptation. This study examines the legitimacy of adaptation from a planning theoretical perspective in Helsinki, drawing on semi-structured interviews and social network analysis to show how adaptation is commonly understood from a rationalist perspective as an apolitical activity with local authorities’ experts designing and implementing adaptation. Nevertheless, some of the central actors understand adaptation as a communicative activity and a common deliberation of solutions. The co-occurrence of disparate paradigms results in ambiguous legitimacy that can impede the successful implementation of local climate change adaptation.     

Recent climate change in the Prince Edward County winegrowing region,Ontario, Canada: implications for adaptation in a fledgling wine industry

There is mounting evidence that climate change is already having an impact on the wine industry, with effects being region specific. In order to understand the capacity of regional wine sectors to adapt to changing climate, it is useful to document the conditions that are important to producers and to identify adaptation and management strategies that are employed in the industry. This paper analyzes climatic conditions and adaptation strategies in the wine region of Prince Edward County Ontario, Canada. Wine producers identified the climate variables most important to their operations and described strategies they use to manage climate-related conditions. The identified variables were analyzed for trends over the study period 1987–2011, and interview data were analyzed in order to categorize adaptive strategies. Results indicate that the wine sector is very sensitive to climate, and the region is already experiencing the effects of climate change, especially with regard to increasing growing season mean minimum daily temperatures, increasing total summer rainfall, and later onset of fall frosts. Adaptive strategies employed by producers are largely learned though collaborative efforts and trial and error. The adaptations are mostly tactical and reactive in the short term, but with continued climate change, these strategies may develop into strategic, anticipatory measures. Climate change has the potential to present both challenges and opportunities to Prince Edward County wine producers, and adaptations will continue to require strong networking and collaborative efforts.     

Aiding multi-level decision-making processes for climate change mitigation and adaptation

Progress towards climate change aware regional sustainable development is affected by actions at multiple spatial scales and governance levels and equally impacts actions at these scales. Many authors and policy practitioners consider therefore that decisions over policy, mitigation strategies and capacity for adaptation to climate change require construction and coordination over multiple levels of governance to arrive at acceptable local, regional and global management strategies. However, how such processes of coordination and decision-aiding can occur and be maintained and improved over time is a major challenge in need of investigation. We take on this challenge by proposing research-supported methods of aiding multi-level decision-making processes in this context. Four example regionally focussed multi-level case studies from diverse socio-political contexts are outlined—estuarine management in Australia’s Lower Hawkesbury, flood and drought management in Bulgaria’s Upper Iskar Basin, climate policy integration in Spain’s Comunidad Valenciana and food security in Bangladesh’s Faridpur District—from which insights are drawn. Our discussion focuses on exploring these insights including: (1) the possible advantages of informal research-supported processes and specifically those that provide individual arenas of participation for different levels of stakeholders; (2) the complexity of organisation processes required for aiding multi-level decision-making processes; and (3) to what extent progress towards integrated regional policies for climate change aware sustainable development can be achieved through research-supported processes. We finish with a speculative section that provides ideas and directions for future research.     

Climate change adaptation strategies for transportation infrastructure in Prince George,Canada

Transport infrastructure is particularly vulnerable to climate impacts as it is designed for long operational lives, and both episodic and seasonal conditions contribute to deterioration, disruption and unsafe incidents. There are some examples of adaptation in transportation design, but many communities do not have the capacity to incorporate climate change considerations into infrastructure planning and management. Researchers worked closely with the City of Prince George, in Central British Columbia, Canada, to build on existing work and explore how the City could plan, design, and maintain roads and other structures to account for climate change. A local steering committee was formed, and created and evaluated 23 potential research topics. Two focus areas were selected for further investigation and explored during a workshop with practitioners, researchers, consultants and other representatives. The workshop precipitated an investigation of projected impacts of climate change on road maintenance and road safety, and plans to explore alternative paving techniques. Outcomes of the case study provide insights regarding climate change and local transportation infrastructure, including: how researchers can engage with local experts to explore adaptation; issues local governments perceive as important; and barriers communities face as they attempt to address vulnerabilities.     

Towards adaptation of agriculture to climate change in the Mediterranean

This study links climate change impacts to the development of adaptation strategies for agriculture on the Mediterranean region. Climate change is expected to intensify the existing risks, particularly in regions with current water scarcity, and create new opportunities for improving land and water management. These risks and opportunities are characterised and interpreted across Mediterranean areas by analysing water scarcity pressures and potential impacts on crop productivity over the next decades. The need to respond to these risks and opportunities is addressed by evaluating an adaptive capacity index that represents the ability of Mediterranean agriculture to respond to climate change. We propose an adaptive capacity index with three major components that characterise the economic capacity, human and civic resources, and agricultural innovation. These results aim to assist stakeholders as they take up the adaptation challenge and develop measures to reduce the vulnerability of the sector to climate change.     

Institutional challenges of adopting ecosystem-based adaptation to climate change

In view of past environmental degradation and anticipated climate change impacts, we assessed the potential for ecosystem-based adaptation in the Murray-Darling Basin, Australia. In a workshop with staff from three Catchment Management Authorities (CMAs) who had jurisdiction over three sub-basins, as well as technical experts, nine adaptation options were identified that ranged from environmental flows, restoring river channel habitat, reoperating infrastructure and controlling invasive species. A Catchment Adaptation Framework was developed and used to assess and compare these adaptation options with each of the CMAs, drawing on interviews with their key stakeholders, to identify the risks, benefits and costs. We found that ecosystem-based adaptation can augment catchment management programs and requires investment in a suite of different but complementary measures to lower risk. Our research found institutional challenges in implementing this approach, including the complexities of multi-agency management, constricting legal requirements, narrow funding arrangements, under-developed institutional capacity, difficulties of implementing catchment-scale programs on private property and the need to adhere to community expectations. These institutional issues are ubiquitous internationally and point to the wider issues of providing sufficient management capacity to support adaptation. The Catchment Adaptation Framework presented here enables river basin managers to systematically assess the adaptation options to better inform their decision-making.     

On the nature of barriers to climate change adaptation

Considerable barriers can emerge in developing and implementing climate change adaptation strategies. Understanding the nature of barriers to adaptation is important so as to find strategic ways of dealing with them. However, our current understanding is limited and highly fragmented across the academic community. This paper aims to bring some conceptual convergence in these debates by applying a systematic review method to assess the current state of knowledge on barriers to adaptation in the peer-reviewed literature. The review results show that: (1) Barriers to adaptation have hardly been defined in the literature and no clear indicators exist so as to identify and assess them systematically. (2) An impressive number of barriers have been reported, but the list of possible barriers is seemingly endless. (3) The most frequently reported barriers relate to the institutional and social dimensions of adaptation. (4) Barriers are identified as configurations of climate and non-climate factors and conditions that emerge from the actor, the governance system, or the system of concern. (5) Barriers are mainly studied in developed countries with a strong focus on water-related domains. (6) The majority of studies on barriers use small-n inductive case approaches while comparative studies across different contexts are limited. (7) Although interventions to overcome barriers are recommended by most studies, empirical studies on interventions are scarce. We present further conceptual clarification and a more precise definition of barriers to adaptation. We conclude that future research should go beyond asking the questions ‘if’ and ‘which’ barriers to adaptation exist and begin asking ‘how’ and ‘why’ barriers emerge.
