Groundwater: a regional resource and a regional governance

Groundwater is a valuable renewable resource for human life. The two major threatening issues being faced by groundwater are its depletion and degradation which affect both the quantity and the quality of groundwater. Though scientific output has progressed well ahead in the domain of groundwater, very little has been done with respect to the establishment of the groundwater governance framework. Groundwater is perceived as a widely distributed resource, but it is fundamentally a local entity. The paper presents the groundwater governance framework from the regional perspective of Fatehgarh Sahib district of Punjab, India—an over-exploited groundwater region.     

Integration, synthesis and climate change adaptation: a narrative based on coastal wetlands at the regional scale

The idea that integration and synthesis are critical for designing climate change adaptation and mitigation is well entrenched conceptually. Here, we review the concepts of adaptation, synthesis and integration and apply them to the case study of coastal wetlands in South East Queensland, Australia. The distribution and condition of coastal wetlands will change as climate changes. This will create conservation challenges and economic costs, but these can be minimised by drawing from a broad sectoral perspective in undertaking adaptation planning and by ensuring integration into policy. Our review indicates that adaptations to sea level rise that are focussed on wetland and biodiversity conservation are likely to have impacts for urbanisation patterns. Planning regulations that provide spatial buffering around wetlands may give rise to more compact urban forms that may lead to reductions in the cost of defence against sea level rise, reduce energy usage per person and provide more green space. However, more compact urban forms could exacerbate heat island effects and place greater burden on the economically disadvantaged as, for example, single-family homes become more expensive. Planning for climate change needs to balance these equity and cross-sectoral issues in order to reduce the likelihood of unforeseen negative consequences.     

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.     

Assessing coastal vulnerability to climate change: comparing segmentation at global and regional scales

Recent concerns about potential climate-change effects on coastal systems require the application of vulnerability assessment tools in order to define suitable adaptation strategies and improve coastal zone management effectiveness. In fact, while various research efforts were devoted to evaluate coastal vulnerability to climate change on a national to global level, fewer applications were carried out so far to develop more comprehensive and site-specific vulnerability assessments suitable to plan possible adaptation measures at the regional scale. In this respect, specific indicators are needed to address climate-change-related issues for coastal zones and to identify vulnerable areas at the regional level. Two sets of coastal vulnerability indicators were selected, one for regional and one for global studies, respectively, concerning the same features of coastal systems, including topography and slope, geomorphological characteristics, presence and distribution of wetlands and vegetation cover, density of coastal population and number of coastal inhabitants. The proposed set of indicators for the regional scale was chosen taking into account the availability of environmental and territorial data for the whole coastal area of the Veneto region and was based on site-specific datasets characterized by a spatial resolution appropriate for a regional analysis. Moreover, a GIS-based segmentation procedure was applied to divide the coastline into linear segments, homogeneous in terms of vulnerability to climate change and sea-level rise at the regional scale. This approach allowed to divide the Veneto shoreline into 140 segments with an average length of about 1 km, while the global scale approach identified four coastal segments with an average length of about 66 km. The performed comparison indicated how the more detailed approach adopted at the regional scale is essential to understand and manage the complexities of the specific study area. In fact, the 25-m DEM employed at the regional scale provided a more accurate differentiation of the coastal area's elevation and thus of coastal susceptibility to the inundation risks, compared to the 1-km DEM used at the global level. Moreover, at the regional level the use of a 1:20,000 geomorphological map allowed to differentiate the unique landform class detected at the global level (e.g., fluvial plain) in a variety of more detailed coastal typologies (e.g., open coast eroding sandy shores backed by bedrock) characterized by a different sensitivity to climate change and sea-level rise. Accordingly, the information provided by regional indicators can support decision-makers in improving the management of coastal resources by considering the potential impacts of climate change and in the definition of appropriate actions to reduce inundation risks, to avoid the potential loss of valuable wetlands and vegetation and to plan the nourishment of sandy beaches subject to erosion processes.     

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.     

协同治理:2030年可持续发展议程与应对气候变化的国际制度分析

对国际议程间的关联性分析已经成为全球治理中的重要问题。特别是,由联合国引领的全球发展与应对气候变化问题,已经占据了当前国际政治议程的首要位置,两者的协同直接影响到全球治理的有效性。《2030年可持续发展议程》与《巴黎气候协定》不仅具有共同的规范性基础,而且两者通过议题衔接和叠加已经形成了密切的治理关系,国际制度关联性日益突出。从目前来看,这种关联性体现了以下特点:第一,嵌入关系。可持续发展议程的目标之一是应对全球气候变化,《巴黎协定》的治理目标已经嵌入联合国可持续发展议程之中,但也与一些目标存在矛盾,因此,协同治理具有必要性。第二,指标对应。《巴黎协定》下的“国家自主贡献”细化项目与可持续发展议程中的大部分指标已经形成对应关系,治理具有同质性。第三,制度间倡议交叉与功能外溢。其协同治理关系具体表现在诸多层面上,特别是在联合国系统内的协调、治理模式的趋同、资金渠道的整合、围绕联合国可持续发展议程所进行的发展机构改革,以及联合进行政策倡议、规则建构及政策制定等方面。从制度关系演变的角度来看,两者协同治理的类型正在发生变化,制度互动在不同层次上不断累积,并逐渐转向伙伴型的协同治理模式。     

Toward legitimate governance strategies for climate adaptation in the Netherlands: combining insights from a legal,planning, and network perspective

In general, the issue of climate change is characterized by uncertainty, complexity, and multifacetedness. In the Netherlands, climate change is in above highly controversial. These characteristics make it difficult to realize adaptation measures that are perceived as legitimate. In this article, we analyze the main difficulties and dilemmas with regard to the issue of legitimacy in the context of climate adaptation. We conceptualize legitimacy from a legal, a planning, and a network perspective and show how the concept of legitimacy evolves within these three perspectives. From a legal perspective, the focus is on the issues of good governance. From a planning perspective, the focus is on the flexibility, learning, and governance capacity. From a network perspective, issues of dialogue, involvement, and support are important. These perspectives bring in different criteria, which are not easy compatible. We describe and illustrate these legitimacy challenges using an in-depth study of the Dutch IJsseldelta Zuid case. From our case study, we conclude that, from a legitimacy perspective, the often acclaimed necessity to be adaptive and flexible is quite problematic. The same holds true for the plea to mainstream adaptation into other policy domains. In our case study, these strategies give rise to serious challenges in relation to good governance and consensus—two indispensable cornerstones of legitimacy.     

Collaborative governance for climate change adaptation in Canada: experimenting with adaptive co-management

The search for strategies to address ‘super wicked problems’ such as climate change is gaining urgency, and a collaborative governance approach, and adaptive co-management in particular, is increasingly recognized as one such strategy. However, the conditions for adaptive co-management to emerge and the resulting network structures and relational patterns remain unclear in the literature. To address these identified needs, this study examines social relationships from a network perspective while initiating a collaborative multiactor initiative aimed to develop into adaptive co-management for climate change adaptation, an action research project undertaken in the Niagara region of Canada. The project spanned 1 year, and a longitudinal analysis of participants’ networks and level of participation in the process was performed. Evidence of support for climate change adaptation from the process included the development of deliberative and adaptive responses to opportunities presented to the group and the development of a strong subgroup of participants where decision-making was centered. However, the complexity of the challenge of addressing climate change, funding constraints, competing initiatives, and the lack of common views among participants may have contributed to the group, highlighting the finding that beneficial network structural features and relational patterns are necessary but not sufficient condition for the development of an adaptive co-management process. The context of climate change adaptation may require a different social network structure and processes than other contexts for adaptive co-management to occur, and there may be limitations to adaptive co-management for dealing with super wicked problems.

Resourcing local communities for climate adaptive designs in Victoria,Australia

This article proposes a new theoretical framework that supports the preparation of local communities to deal with climate impacts.In this framework,derived from the metabolism model,the resources that form the input(social capital and practical conditions)for design charrettes are processed to deliver output resources in the form of enhanced and sophisticated spatial design propositions,which are more resilient en adaptive.Elaborating this model,processing input to deliver desired outputs can only occur when deep learning experiences are offered to the local community.The framework is used and tested in two case studies in northwest Victoria,the City of Bendigo and town of Sea Lake.The findings from the study show the performance of the framework and the improved properties of the design propositions.Conducting design charrettes has two effects.New ways of collaboration are explored allowing exchange to happen between community members with different interests.This leads to new social constructs that are capable of achieving results that would be otherwise impossible or unknown of.Secondly,the design propositions suggest highly resilient and adaptive spatial transformations in the city or town.     

Formaldehyde in China: Production, consumption, exposure levels, and health effects

Formaldehyde, an economically important chemical, is classified as a human carcinogen that causes nasopharyngeal cancer and probably leukemia. As China is the largest producer and consumer of formaldehyde in the world, the Chinese population is potentially at increased risk for cancer and other associated health effects. In this paper we review formaldehyde production, consumption, exposure, and health effects in China. We collected and analyzed over 200 Chinese and English documents from scientific journals, selected newspapers, government publications, and websites pertaining to formaldehyde and its subsequent health effects.Over the last 20 years, China's formaldehyde industry has experienced unprecedented growth, and now produces and consumes one-third of the world's formaldehyde. More than 65% of the Chinese formaldehyde output is used to produce resins mainly found in wood products — the major source of indoor pollution in China. Although the Chinese government has issued a series of standards to regulate formaldehyde exposure, concentrations in homes, office buildings, workshops, public places, and food often exceed the national standards. In addition, there have been numerous reports of formaldehyde-induced health problems, including poisoning and cancer. The lack of quality epidemiological studies and basic data on exposed populations emphasizes the need for more extensive studies on formaldehyde and its related health effects in China.     

Forest plantations, water availability, and regional climate change: controversies surrounding Acacia mearnsii plantations in the upper Palnis Hills, southern India

Plantation forests not only impact carbon and water cycles, but also affect biodiversity, livelihoods, and shape regional economies. Each of these impacts differs across varying scales of analysis. This paper illustrates how forest, climate change and hydrology debates play out in the context of the forest plantations of Australian black wattle (Acacia mearnsii) in the upper Palni hills of southern India. We outline the contradictory perspectives of different local groups regarding the impact of plantations on catchment hydrology and water availability, and examine these in relation to changes in the regional economy and rainfall patterns. Our analysis indicates that changes in these two factors have played a more significant role than existing wattle plantations in affecting local and regional water availability. We suggest that ongoing debates regarding forest plantation–hydrology–climate change relationships need to broaden their scope to include changes in regional rainfall patterns and shifts in regional economic activity. This approach is likely to provide a more realistic assessment of plantation forests in a dynamic regional context, and offer more resilient strategies for regional landscape and catchment management under conditions of high variability in rainfall patterns.

Statistical downscaling for climate change projections in the Mediterranean region: methods and results

Besides dynamical downscaling by regional climate models, statistical downscaling (SD) is a major tool to derive climate change projections on regional or even local scales. For the Mediterranean area, an increasing number of downscaling studies based on different statistical techniques have been published in the last two decades with a broad range of sometimes differing results relating to different variables and regional domains. This paper gives a short review of these Mediterranean downscaling studies mainly considering the following two aspects: (1) what kind of progress has been realized in this field since the early 1990s? The review addresses the inclusion of extremes in downscaling assessments, the development of probabilistic approaches, the extension of predictor sets, the use of ensembles for both dynamical model simulations and statistical model assessments, the consideration of non-stationarities in the predictor–predictand relationships, and some advances related to synoptic downscaling. (2) What are the main regional climate change signals in the Mediterranean area, considering agreed and controversial points also with respect to dynamical models? Best accordance among future projections can be found in seasonal temperatures with lower rates of warming in winter and spring, and, in most cases, higher ones in summer and autumn. Different results are obtained for the intra-annual range of extreme temperatures, but high-temperature conditions are generally expected to increase. Regarding seasonal precipitation, predominant reductions are indicated for spring, summer, and autumn. For winter, however, projections are distinctly different (GCMs: rainfall decrease; RCMs: increase only in the northernmost parts of the Mediterranean region; SD: widespread increases in the northern and western parts in several studies). Different results are obtained for rainfall extremes, but the entire precipitation distribution tends to shift towards higher and lower values. Apart from some sub-regional deviations, there is a predominant increase in future dry period durations. For near-surface winds, only a few studies are available, and they project some decline mainly for the winter season.     

Moving beyond the conceptual: specificity in regional climate change adaptation actions for biodiversity in South East Queensland,Australia

While many scientific assessments have been recommending general strategies for biodiversity conservation under climate change, translation of these recommendations into specific actions and practice has been limited. Focusing on two biomes, rainforest and wetlands in biodiverse South East Queensland, Australia, we demonstrate how general principles can be translated into specific actions for stakeholders and responsible agencies. We synthesize research that is contextualizing protection of refugia and habitat connectivity, establishing baseline data sets to detect change and developing strategic conservation planning scenarios to adjust reserve boundaries or situate new reserves. This has been achieved by coupling spatial information on biological assets (i.e. ecosystems and species) with future climate scenarios and process models to anticipate movement of critical habitats. Conservation planning software is also being used to prioritize investment to meet specific objectives. This approach is enabling us to identify at-risk biological assets, opportunities to ameliorate threats and obstacles to delivering regional adaptation actions. A larger total reserved area is needed, with proactive planning to capture areas further inland and along watercourses. Major obstacles include conflict between urbanization and priorities for habitat conservation and the need for greater levels of investment for monitoring programmes and to protect landward shifted wetlands on private land.
