Energy transition,CO2 mitigation,and air pollutant emission reduction: scenario analysis from IPAC model

The salinization of freshwater-dependent coastal ecosystems precedes inundation by sea level rise. This type of saltwater intrusion places communities, ecosystems, and infrastructure at substantial risk. Risk perceptions of local residents are an indicator to gauge public support for climate change adaptation planning. Here, we document residential perspectives on the present and future threats posed by saltwater intrusion in a rural, low-lying region in coastal North Carolina, and we compare the spatial distribution of survey responses to physical landscape variables such as distance to coastline, artificial drainage density, elevation, saltwater intrusion vulnerability, and actual salinity measured during a synoptic field survey. We evaluate and discuss the degree of alignment or misalignment between risk perceptions and metrics of exposure to saltwater intrusion. Risk perceptions align well with the physical landscape characteristics, as residents with greater exposure to saltwater intrusion, including those living on low-lying land with high concentrations of artificial drainages, perceive greater risk than people living in low-exposure areas. Uncertainty about threats of saltwater intrusion is greatest among those living at higher elevations, whose properties and communities are less likely to be exposed to high salinity. As rising sea levels, drought, and coastal storms increase the likelihood of saltwater intrusion in coastal regions, integrated assessments of risk perceptions and physical exposure are critical for developing outreach activities and planning adaptation measures.

     

Cryospheric hazards and risk perceptions in the Sagarmatha (Mt. Everest) National Park and Buffer Zone,Nepal

Glacial lake outburst floods (GLOFs) are among the most serious cryospheric hazards for mountain communities. Multiple studies have predicted the potential risks posed by rapidly expanding glacial lakes in the Sagarmatha (Mt. Everest) National Park and Buffer Zone of Nepal. People’s perceptions of such cryospheric hazards can influence their actions, beliefs, and responses to those hazards and associated risks. This study provides a systematic approach that combines household survey data with ethnography to analyze people’s perceptions of GLOF risks and the socioeconomic and cultural factors influencing their perceptions. A statistical logit model of household data showed a significant positive correlation between the perceptions of GLOF risks and livelihood sources, mainly tourism. Risk perceptions are also influenced by spatial proximity to glacial lakes and whether a village is in potential flood zones. The 2016 emergency remediation work implemented in the Imja Tsho (glacial lake) has served as a cognitive fix, especially in the low-lying settlements. Much of uncertainty and confusions related GLOF risks among locals can be attributed to a disconnect between how scientific information is communicated to the local communities and how government climate change policies have been limited to awareness campaigns and emergency remediation efforts. A sustainable partnership of scientists, policymakers, and local communities is urgently needed to build a science-driven, community-based initiative that focuses not just in addressing a single GLOF threat but develops on a comprehensive cryospheric risk management plan and considers opportunities and challenges of tourism in the local climate adaptation policies.

     

Perceptions of environmental change in Moorea,French Polynesia: the importance of temporal,spatial, and scalar contexts

Pacific Islands are considered among the most vulnerable geographies and societies to the effects of climate change and variability (CCV). This study addresses the mismatch between global climate change narratives and local perceptions of environmental change in Moorea, French Polynesia. This study builds on CCV risk perception and adaptation research by analyzing how temporal and historical socio-economic, cultural, political, and ecological contexts shape local perceptions of environmental change among a sample of environmental stakeholders in Moorea. The data were collected prior to the widespread global narrative and social amplification of climate change risk and its particular impact on islands. As such, they offer an important portrait of environmental perceptions in French Polynesia prior to the influence of a circumscribed climate change narrative, which has since come to shape government and NGO responses to environmental change in the Pacific Island Countries and Territories. The data presented in this paper illustrate that perceptions of drivers and effects of environmental change and risk in Moorea are embedded in larger social processes of political economy and ecology, particularly related to contemporary environmental politics, contextualized within the histories of colonialism and tourism-led economic development. Integrating the complexity of local environmental risk perceptions into CCV policy will help to avoid maladaptation, social movements against CCV planning, and may help maximize government and donor investments.     

Power,perception, and adaptation: Exploring gender and social–environmental risk perception in northern Guanajuato,Mexico

This paper examines how gender relations within rural communities in north-central Mexico affect women’s perceptions of and responses to environmental and social risks. Several studies currently exist which suggest various reasons as to how people especially vulnerable to the effects of climate change perceive their risks, and how this influences their responses. In this paper, I take a feminist approach to questions of social–environmental risks and adaptation to argue that risk perception is tightly linked to knowledge production, and knowledge production is a power-laden process involving the constant negotiation of resources, responsibilities and knowledge. I base this argument on the results of fieldwork conducted from September 2009 to May 2010 with women residents of two ejidos in northern Guanajuato, Mexico. In drawing from feminist political ecology studies, I intend to show how gender, environmental knowledge, risk perception and thus, adaptation are constituted by and embedded in social relations of power.     

Socio-cultural dimensions of climate change: charting the terrain

We have reached a crucial turning point in debates around climate change. A well established scientific consensus regarding the physical causes, dynamics, and at least many likely implications of anthropogenic climate change has thus far failed to result in any substantial movement towards mitigation. For many, then, the most urgent questions regarding climate change are now socio-cultural ones, such as: how do people come to hold and act on certain beliefs regarding environmental conditions and processes; how do institutional forms and histories shape and constrain the views and options of various sorts of actors; and what are relationships among fossil fuels, climate change, and the historical geographies and future trajectories of capitalism? Far from being simpler than physical and life science questions, these social science questions introduce entirely new sorts of actors, dynamics, and methodological challenges into this already complex and dynamic domain. This special issue takes up these topics. In this essay, we chart some of the major contours of contemporary social science thinking regarding climate change and introduce the articles in the special issue. We begin by examining work, from political science and scholarship on the commons, that foregrounds questions of sovereignty, territoriality, and cooperation with respect to environmental governance. Then we examine work from neoclassical economics and radical political economy, which frame climate change in terms of externalities, or contradiction and crisis, respectively. Finally, we examine the rapidly proliferating work exploring how individuals think and feel about these issues, emphasizing concepts of risk, communication, and governmentality.     

Unstable climates: Exploring the statistical and social constructions of ‘normal’ climate

The idea of climate has both statistical and social foundations. Both of these dimensions of climate change over time: climate, as defined by meteorological statistics, changes for both natural and anthropogenic reasons; and our expectations of future climate also change, as cultures, societies and knowledge evolves. This paper explores the interactions between these different expressions of climate change by focusing on the idea of ‘normal’ climates defined by statistics. We show how this idea came into being in meteorological circles and then review how this idea of climatic normality gets entangled with cultural and psychological processes. Using data from historical and predicted climates in the UK, we illustrate the significance of choosing different baseline ‘normals’ for retrospective and prospective interpretations of climate change. Since the choice of these statistical ‘normals’ reflects cultural, political and psychological preferences and practices as much as scientific ones, we argue that expectations of the climatic future are influenced by social as well as statistical norms. Seeing climate as co-constructed between the psycho-cultural constraints of society and the physical constraints of the material world offers a different way of thinking about the instabilities of climate and the ways we adapt to them.     

Nature–society and development: social, cultural and ecological change in Nepal

This paper presents a theoretical framework for analyzing human–environment issues that examines shifting, dialectical relationships between social and power relations, cultural beliefs and practices, and ecological processes to allow an interdisciplinary, complex assessment of social and environmental change in Nepal. The purpose of this analysis is to capture the complexity and non-static nature of environmental and social change in the context of uneven development. Drawing from political ecology and feminist geography, this framework brings together scholarship on aspects of human–environment issues that are often pursued in isolation, yet all three processes, social–political relations, cultural practices and ecological conditions, have been acknowledged as important in shaping the trajectory of social and ecological change. I argue that a consideration of the articulations between them is necessary to understand first, how specific land management regimes arise and are dominant over time in specific places. And second, I examine the extent to which these regimes distribute resources equitably within communities, promote economic development and sustain ecological resilience. In this analysis, ecological processes are conceptualised as co-productive of social and cultural processes to explore their role in land management regimes without resorting to environmental determinist or similarly reductive paradigms. I present this framework through the example of natural resource management, specifically community forestry in Nepal, as it offers a rich case study of the relationships between the political economy of land use and the ecological effects of natural resource extraction.     

Amenity migration: diverse conceptualizations of drivers,socioeconomic dimensions,and emerging challenges

Rural communities throughout the postindustrial world are in the midst of a significant transition, sometimes referred to as rural restructuring, as traditional land uses, economic activities, and social arrangements transition to those associated with “post-productivist” or “multifunctional” landscapes. Amenity migration, the movement of people based on the draw of natural and/or cultural amenities, can be thought of as both driver and implication of this transition, resulting in significant changes in the ownership, use, and governance of rural lands, as well as in the composition and socioeconomic dynamics of rural communities. In concert with other social, economic and political processes, amenity migration is contributing to the fundamental transformation of rural communities throughout the world. This paper presents a review of the social science literature related to the concept of amenity migration, focusing on the ways in which it has been conceptualized, theorized, and documented by different communities of scholars. We then profile and summarize diverse perspectives on drivers and socioeconomic impacts, highlighting emerging challenges and opportunities related to this type of migration occurring at multiple scales and in multiple sites. The paper also identifies and discusses particular areas where further research is needed.     

Reverse osmosis on a small barrier island: transformations of water,landscape, and vulnerability on Ocracoke Island,NC, USA

Globally, modifications to the landscape have drastically transformed social and ecological communities. The implication of global climate change for small islands and small island communities is especially troublesome. Socially, small islands have a limited resource base, deal with varying degrees of insularity, generally have little political power, and have limited economic opportunities. The physical attributes of small islands also increase their vulnerability to global climate change, including limited land area, limited fresh water supplies, and greater distances to resources. The focus of this research project is to document place-specific human–environmental interactions from a political ecology perspective as a means to address local concerns and possible consequences of global environmental change. The place in which these interactions are examined is the barrier island and village of Ocracoke, NC. I focus on the specific historical-geography of land and water management on Ocracoke as a means to examine relationships between local human–environmental interactions and environmental change. I provide an account of technological changes in potable water procurement and the paralleling development of island growth (i.e. people, buildings, tourism). Then, relying on interviews with island residents, I consider how advancements in local water infrastructure, specifically the installation of an additional reverse osmosis unit, are hinged on anticipated future economic development. Lastly the social dimensions of change are discussed with specific focus on the increase in housing density and overburdened septic drainage fields in relation to changing hydrologic processes with an examination of how all of these factors affect local vulnerability.     

Debris flow hazards for mountain regions of Russia: regional features and key events

The total area of debris flow territories of the Russian Federation accounts for about 10% of the area of the country. The highest debris flow activity areas located in Kamchatka-Kuril, North Caucasus and Baikal debris flow provinces. The largest debris flow events connected with volcano eruptions. Maximum volume of debris flow deposits per one event reached 500 × 10⁶ m³ (lahar formed during the eruption of Bezymyanny volcano in Kamchatka in 1956). In the mountains of the Greater Caucasus, the maximum volume of transported debris material reached 3 × 10⁶ m³; the largest debris flows here had glacial reasons. In the Baikal debris flow province, the highest debris flow activity located in the ridges of the Baikal rift zone (the East Sayan Mountains, the Khamar-Daban Ridge and the ridges of the Stanovoye Highland). Spatial features of debris flow processes within the territory of Russia are analyzed, and the map of Debris Flow Hazard in Russia is presented. We classified the debris flow hazard areas into 2 zones, 6 regions and 15 provinces. Warm and cold zones are distinguished. The warm zone covers mountainous areas within the southern part of Russia with temperate climate; rain-induced debris flows are predominant there. The cold zone includes mountainous areas with subarctic and arctic climate; they are characterized by a short warm period, the occurrence of permafrost, as well as the predominance of slush flows. Debris flow events are described for each province. We collected a list of remarkable debris flow events with some parameters of their magnitude and impact. Due to climate change, the characteristics of debris flows will change in the future. Availability of maps and information from previous events will allow to analyze the new cases of debris flows.     

No boundaries: exurbia and the study of contemporary urban dispersion

The dream of a house in the country, at the seashore, or near a ski hill, is one shared by many in North American society. But the environmental and social impacts of the realization of this dream by an increasing number of people has created crises and conflict for many communities. The concept of exurbia has traditionally been used to describe settlement patterns simultaneously dispersed from the city yet also connected to urban networks. This paper reviews scholarship across disciplines including geography, ecology, sociology, and political ecology. Exurbia is here proposed to be strengthened as a powerful conceptual approach to capture and discuss the complex processes producing this phenomenon. Previous scholarship has produced excellent but largely disconnected work on the periurban zone around cities, exurban settlement processes, tensions between exurbanites and other rural residents, environmental impacts and habitat fragmentation. Future work on exurbia holds a great deal of promise to think about cultural values supporting the processes that produce these landscapes, working across scales from local to global using interdisciplinary and multi-method study.     

Another look at An Inconvenient Truth

The portrayal of the science of climate change in An Inconvenient Truth is largely correct. Some aspects of the film, such as the discussion of Hurricane Katrina, oversimplify the complex factors involved, while others conflate global warming with other environmental changes that may not be related. However it is not in question that continuing emissions of greenhouse gases by human activities will cause greater climate change in the future, and that the impacts of such change are likely to be negative. The chief message of the film—that this fact places important moral and ethical choices before society—is therefore an accurate one.     

Gated communities: From “Self-Sufficient Towns” to “Active Urban Agents”

The growing research on gated communities has largely regarded them as isolated and isolating places, rather than considering residents’ relations with other spaces and communities. This paper seeks to examine these external contacts through exploring the ways in which gated communities establish relations with local political actors. This is done through an examination of two gated communities in Gokturk and Omerli, Istanbul, and an analysis of the differences between them. On the basis of semi-structured in-depth interviews with residents and locals, the paper demonstrates how gated communities engage with the outside world in contrasting ways. By focusing on the conflict between Islamist and secular people, the paper also argues that gated communities are active urban agents, establishing interdependent relations with local political actors which can change urban space and politics.

An overview of climate change impacts on the society in China

Society could sustain the impact of climate change by adapting to the change and mitigating risks from adverse effects of increasing changes, so that it can continue maintaining its prospect and improving wellbeing. Nevertheless, climate change is more or less affecting society's functions at different scales, including both individuals and communities. In this review, we discuss the relationship between society and climate change in China from the aspects of the needs at different socioeconomic developing stages. The relationship as well as the current spatial pattern and future risks of the climate change impacts on societies are summarized. The complexity of social and climatic systems leads to the spatial heterogeneity of climate impacts and risks in China. To more effectively leverage increasing knowledge about the past, we advocate greater cross-disciplinary collaboration between climate adaption, poverty alleviation and Nature-based Solutions (Nbs). That could provide decision makers with more comprehensive train of thoughts for climate policy making.

Introduction to themed issue: “Green security in protected areas”

This introduction to the themed issue discusses the articulation of protected areas, conservation, and security in issue contributions. Protected areas are presented as localized sites to address global crises, such as anthropogenic climate change and the “war on terror.” When they are sites for securitization and militarization, protected areas articulate state and subject formations through violence. As threat discourses have amplified in recent years, communities once deemed putative eco-destroyers have been interpellated as potential threats in wars on drugs and/or terror. The themed issue reveals that reframing environmental crime as organized crime has significant implications for expanding claims of what counts as legitimate use of force in protected areas policing, as well as potential prosecutions. It is apparent that security for one group may hinge on the insecurity of another group at different historical and political moments. In this special issue we challenge conservation actors as well as those critical of conservation to ask: for whom does conservation provide security, under what circumstances, and at what cost?
