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

At the center of community geography is a commitment to mutually beneficial and co-produced knowledge. While the intricacies of managing these two commitments are often well-articulated for community partners, university faculty and their undergraduate students, the experiences of precariously positioned researchers (such as graduate students or those who work outside the university) remain under-examined. Therefore, through a reflection on the authors’ personal experiences facilitating community geography projects, this paper takes seriously the experiences of precariously positioned researchers. We highlight how the privileging of co-production creates moments of dissonance for precariously placed researcher’s experiences of mutually beneficial research. We argue that precarity, particularly when paired with privilege, results in heightened feelings of risk that may lead researchers to compromise their own ethics or values to ensure both the ongoing continuation of the partnership and the desired goals of the community partners. As we work to further establish community geography, we call for more nuanced considerations of how the entanglements fostered through co-production impact experiences of mutually beneficial research for differently positioned researchers, particularly for those situated within in the neoliberal university. 相似文献

What does it mean to conduct community-based and praxis-oriented research at a time when those whose lives you study and with whom you work are the subjects of increasing levels of xenophobia, marginalization, and demonization? How does one conceive of research ethics, of the relationship between the roles of scholars, teachers, and citizens in light of such dynamics? In what ways can scholarship help to intervene in the world around us, in particular to improve the perception and amplify the voices of marginalized groups and individuals? This paper considers these issues in the context of research ethics and the growing field of community geography. I draw in particular on an example from a multi-year study of refugee resettlement in non-traditional destinations across the US. When the study began, refugee policies and settlement patterns were little known to the general public in the US. Since then, refugees and migration more broadly have become increasingly prominent and controversial worldwide. In this paper I explore some of the challenges regarding collaborations between university researchers and community partners, highlighting the tensions exposed through the use of the visualization technique known as Photovoice, meant to provide alternative perspectives on ideas for urban change amongst participants. I also consider some ideas for steps to address these challenges, including the building of networks and training for researchers and formalized partnership processes for community groups. 相似文献

This CAPE Inaugural Lecture poses the question “should some political ecology (PE) be useful?” and reviews the challenges and opportunities facing academic researchers wishing to engage with policy makers, politicians, activists, the media and social movements in both the global North or South. Environmental justice provides an ethical justification for political engagement, but an essentially critical and challenging PE can put off research funders and international and national actors in policy making spheres. PE, especially post-structuralist PE, is often ill-understood and distrusted by many both inside and outside the academy, and a critical realist approach is better recognised by many intended audiences. There are many reasons given to resist an engaged PE, especially as PE has been and continues to be associated with “development”. A practical and dynamic approach to engaged PE research is suggested. 相似文献

Efforts in the United States to plan or implement relocation in response to climate risks have struggled to improve material conditions for participants, to incorporate local knowledge, and to keep communities intact. Mixed methodologies of community geography provide an opportunity for dialogue and knowledge-sharing to collaboratively diagnose the challenges of climate adaptation led by communities. In this article, we advance a participatory practice model for the co-creation of knowledge initiated during a two-day workshop with members from the Biloxi-Chitimacha-Choctaw Tribe from Isle de Jean Charles in Louisiana, Yup’ik people from Newtok Village in Alaska, and researchers from the MIT Resilient Communities Lab. Building on prior scholarship of indigenizing climate change research, this article shares the experience of the workshop to support knowledge exchange and dialogue, with the goal of understanding how to build participatory and non-extractive community-academic partnerships. We reflect on the community values and principles used to guide this workshop to inform more inclusive and co-produced research partnerships, and pedagogies that can improve and assist the self-determination of groups impacted by climate change. Workshop presentations and discussions highlight interconnected themes of resources, systems & structures, regulatory imbalance, and resilience that underpin climate resettlement. We reflect on the narratives presented by members of both Indigenous tribes and NGO partners that illustrate the shortcomings of resettlement planning practices past and present as perpetuating existing inequality. In response to this structured knowledge exchange, we identify potential roles for community-academic partnerships that aim to improve the equity of existing resettlement models. We propose approaches for incorporating traditional knowledge into the pedagogy, discourse, and practice of academic planning programs. 相似文献

The paper offers a critical intervention into the debates on research impact, theorising the potential of underpinning research agendas by ethics of care. We explore how a range of vectors of care, both intimate and distant, emerged in collaborative activities between researchers based in the UK and community youth workers and teenage female carers in Slovakia, leading to a series of (un)expected outcomes. We argue that while all research impacts cannot be planned in advance, an ethics of care embedded in relationships within and beyond research settings may form conditions in which outcomes exceeding the initial expectations can be anticipated. To achieve this, we argue for questioning the distinctions between academic and non-academic collaborators, legitimising diverse forms of knowledge, action and impact in institutional policies, and for conceiving research projects from the beginning as “more-than-research” avenues. 相似文献

‘Community geography’ is a growing sub-field that leverages academic resources to facilitate spatial research in partnership with local communities. The Mapping Prejudice Project and the CREATE Initiative, two interdisciplinary projects at the University of Minnesota, demonstrate some of the opportunities and challenges associated with practicing community geography. Mapping Prejudice is leveraging community crowdsourcing to build the first comprehensive spatial database of racially restrictive housing covenants in the United States. CREATE is co-developing research on critical problems at the intersection of environment and equity through collaboration with community partners. These two projects incorporate a methodological commitment to place-based and historically grounded research that seeks to make knowledge in—and in relation to—a specific place. Incorporating earlier feminist and critical GIS theory, these projects have adopted an iterative research model that places under-resourced communities at the forefront of the research process. Their work produces a fluid, responsive, and co-creative approach that has the capacity to legitimate its knowledge claims through responsiveness to community needs and collective experience. 相似文献

Participatory research is supposed to involve participants in a collective definition of goals, and the co-production and sharing of research outputs. However, when articulated through an extended period of time involving a range of local, national and international actors, the practicalities of participatory research means that certain groups and individuals become responsible for taking leading roles, with subsequent ethical dilemmas. In the ‘Community-owned solutions for future environmental challenges in the Guiana Shield, South America’ (COBRA) project, the participatory research process involves a group of five Indigenous researchers – “the local team” – in charge of carrying out the research on the ground e.g. defining procedures, carrying out community engagement and supporting the communities in analyzing and disseminating the material. This local team is, in turn, supported by researchers from a national NGO and foreign academics.Considerable responsibility has been given to the local team for achieving project outcomes, and freedom in defining project tasks and activities. This paper analyses the multiple ethical dilemmas arising out of this situation, particularly the role of the local team as intermediaries between the wider community and project partners. We highlight the existence of significant mismatches between research expectations, and the ethical processes in operation at community level which are usually established on long-term, tacit and reciprocal relationships. We discuss how local community researchers are challenged with balancing the tensions between these two ethical polarities, while at the same time producing participatory research outcomes that are acceptable by everyone involved. 相似文献

With the increasing occurrence of disasters, how to respond to disasters has attracted a lot of interest. However, a systematic study of emergency response in disasters (ER) has been ignored. Based on the bibliometric analysis and visualization of 3678 journal articles (1970–2019) related to ER from the Web of Science, the current research situation in the field of ER has been studied. The important research questions and trends in the field of ER have been identified. In this study, the VOSviewer software is used to visually analyze publications about ER. Specifically, the most influential journals and authors, highly cited publications, authoritative research institutions, and co-citation are identified in this study. Moreover, the Ucinet software is applied to analyze the social network of 45 high-frequency keywords and the Citespace software is used to study the keyword citation bursts. The results show that the keywords “optimization” and “demand” are the most popular research interests. Besides, four main research topics on ER are summarized, which are emergency supplies and facility-related research, emergency preparedness and security-related research, emergency decision system-related research, and emergency medical rescue and cure-related research. Finally, this study puts forward the research work that should be paid attention to in the future according to different research topics, which can help researchers to understand the ER research progress systematically and focus on emerging research questions. 相似文献

Abstract This paper gives an answer to the criticism of Jussereta and Baeteman to the paper Discussion of “Relative sea level fluctuations in Aegean coastal areas from middle to late Holocene” by Kosmas Pavlopoulos [Geodinamica Acta 23/5–6 (2010) 225–232]. Jussereta and Baeteman were critical about how the peat beds can be regarded as certain sea level indicators. It is evident that the method adopted for the determination of the mean sedimentation rate of the peats beds is the dating of two distinct (usually basal and uppermost) layers. A common inaccuracy that some researchers do when they refer to relative sea level changes, is to focus only on eustatic component of this process, and to ignore the rest two (isostatic and tectonic). Jussereta and Baeteman do not believe that a particulate site could suffer alternate stages of subsidence and uplift. However, Aegean Sea is an area of high tectonic potential, which has shaped by the interplay compression and extension forces. Finally, this answer gives evidence that the observational data concerning the Holocene RSL stands in unstable localities can be compared with those data extracted from a hydro-isostatic model to estimate rates of vertical displacement and, therefore, to detect uplifting, relative stable and subsiding regions. This approach is followed by many researchers who study various Mediterranean coasts © 2011 Lavoisier SAS. All rights reserved 相似文献

新元古代晚期约635 Ma的地球发育了到达赤道附近的冰川作用，地质记录上表现为代表寒冷气候的冰期沉积杂砾岩，直接被代表温暖环境的碳酸盐岩层（常称盖帽碳酸盐岩）覆盖。由于盖帽碳酸盐岩奇特的岩石学和地球化学特征，引起了对其成因认识的巨大争论，提出了“雪球地球”和“甲烷渗漏”等假说。“雪球地球”假设可以解释一些令人困惑的地学现象，如低纬度和低海拔冰川沉积、盖帽碳酸盐岩、碳酸盐δ13C负漂移和条带状铁矿层等，但许多科学家对此提出了质疑。最近对盖帽碳酸盐岩的δ13C分析结果（最低达-41‰）、盖帽碳酸盐岩发育的类似现代冷泉碳酸盐岩沉积组构等似乎支持“甲烷渗漏”假说。 相似文献

The terms “diaspora” and “diaspora strategies” are both used in inconsistent, and often, conflicting ways. Who encompasses “the diaspora” and what are “diaspora strategies”? What roles do ethnicity and affinity play in conceptualizing relationships between diasporas and homeland governments? This paper extrapolates from programs and organizations that link overseas coethnic and former resident non-coethnic populations to Japan to offer clarity and consistency in usage by bringing together concepts not typically put in conversation with each other and introducing new terms that conceptualize more specific aspects of who we are referring to as “diaspora” and what we are referring to as “diaspora strategies”. Conceptualizations of diaspora often gloss over internal differences, including whether or not people deemed members of a diaspora actually demonstrate a homeland orientation. Focusing on the difference between ethnicity-based and affinity-based definitions of diaspora, I distinguish between three types of diaspora strategies: “diaspora-connecting”, “diaspora-cultivating”, and “diaspora-creating strategies”. Finally, as a way to discuss the potential contributions of both overseas coethnic and non-coethnic populations to a given nation, I conclude by considering Joseph Nye’s notion of “soft power” in relation to diaspora strategies. By engaging these concepts together, the paper highlights the tensions between considering ethnicity and affinity as factors for deciding who to target for diaspora strategies, and demonstrates how diaspora strategies can also target non-coethnics. 相似文献

Migration is a global strategy for promoting economic growth and sustainable urbanization, specifically in developing countries. It is critical for governments to understand the determinants of migration decision for rural households so that proper migration measures can be taken. Different from previous studies that mainly focus on migration determinants without considering migration patterns, this paper divides migration patterns into three types—no migration, labor migration, and family migration, and examines the determinants for “no migration–migration” and “labor migration–family migration,” respectively. The binary logistic model is adopted to analyze the impacts of various migration factors in Chongqing city. Results show that: (1) per capita non-agricultural income plays the most significant positive role in driving “no migration–migration.” This is followed by the number of household labor force, whereas road accessibility is the key factor for inhibiting migration. (2) The key contributory factor for “labor migration–family migration” is per capita non-agricultural income. This is followed by the residential distance from towns, whereas the number of household labor force and the average age of labor force are restraining factors. The research results can effectively provide scientific reference for local governments to advance the transfer of the surplus rural labor force to promote sustainable urbanization. 相似文献

This paper on “Temperature changes in earth-history” is an extension of a lecture given as an introduction to a section of equal title on the annual meeting of the Geologische Vereinigung, March 1976, in Hannover. The general development of paleoclimatological research in the last 300 years is represented on two diagrams (fig. 1–2) showing also the part of different climatic indicators. Otherwise, however, mostly new results and problems of the last years are treated (mainly papers since 1973; references of older literature are to be found in the 3 rd edition of the author's book on “Climates of the Past” = “Klima der Vorzeit”, Enke/Stuttgart 1974). This paper refers a) to some short comments on certain climatic indicators as diamictites (a similar term is Schermerhorn's “mixtite”, but “diamictite” is 6 years older and has therefore priority to “mixtite”) and “stellate nodules” (in the chapter “Mesozoic”) indicating perhaps cool climate in the Arctic. - b) Some great ice-ages are briefly discussed: Huronian (very important because of its old age); Late Proterozoic (“Eocambrian”) with many problems on account of its pretended worldwide extension. but with many uncertainities (partly pseudotillites, inconsistent paleomagnetic poles, combination of tillites with dolomites etc.); Permo-Carboniferous (many hypothesises up to 1975 try to explain the pretended “equatorial” position of tillites); Cenozoic ice-age (once “Quaternary” ice-age), with table 1 indicating some possibilities to evaluate the beginning of glaciations in Tertiary time (fig. 4). Why does glaciation start in Antarctica in the Tertiary? (Not or not only on account of drift via South Pole, but perhaps because of high relief and changes in global paleogeography). — c) Diagram of the great ice-ages in earth-history (fig. 6 b): it probably shows not all ice-ages but only the known ones indicating their maxima (i. e. times when inlandice extended to middle latitudes). This curve is probably essentially correct back to 300–400 m. y. yet especially the Precambrian time is still mostly paleoclimatic noman's-land. It is not possible to fix beginning and end of the Pre-Tertiary ice-ages exactly but at any rate the “akryogene” climates lasted longer than the “kryogene” ones (“kryogene” defined as climate with “much ice” [“pleistokryogene”], “akryogene” not as climate “without ice” but as climate with “a little ice” [“oligokryogene”]). - d) Periodicities in the temperature history: before exact dates were available (especially for Late Proterozoic and Huronian ice-ages) and before the Sahara glaciation of the Old Paleozoic was known, a periodicity of 250–300 m. y. was likely to exist. Therefore relations to the “Galactic year” were reasonable, stimulating attempts to find out plausible mechanisms for such a relation. But now, such a periodicity seems unlikely to exist (and much more one of 155 m. y., supposed by Williams). The relative constancy of global earth temperatures over at least more than 2 billion years is more striking than their variations, though regionally the depressions may be very conspicious (in the middle, “sensitive” latitudes). Such depressions, however, are triggered by very small climatic changes on account of the existence of a hydrosphere with temperatures very favorable for a transformation of water into ice and vice versa. No other celestial body of our solar system has these optimal conditions with the consequences of occasional initiation of ice-ages. Ice ages, so to speak, are an inherited pecularity of the earth. The earth is the only “Ice-age Planet”. Under these circumstances, relatively small factors may cause ice-ages: multilateral origin of climatic changes. The most efficient parameters may be paleogeographic variations (relief etc. inclusive continental drift). Some comments are made on the radiation curves reflecting not the direct cause of glacials and interglacials but perhaps shorter climatic variations as they appear possibly in the curves of ocean temperatures ( Emiliani etc.). Volcanic ashes seem not to have any farreaching influence on global temperatures; at least it is geologically impossible to support appropriate hypothesises by observations on continental volcanic sequences. The number of ash-layers in deep-sea cores may reveal sounder arguments though much more observations are needed to corroborate this supposition. — Table 2 gives a summary of the primary (planetary), secondary (multilateral) and — in special situations — tertiary “autocyclic” causes of climatic changes. Table 3 focuses on autocycles i. e. mechanisms which run. off automatically and could have caused the regular climatic variations in the Late Pleistocene with the classic glacialinterglacial sequence (not known from the older Quaternary or Pre-Tertiary ice-ages). In my opinion the most probable hypothesises on autocycles are those which were founded on wide extending subarctic continents of the northern hemisphere (qualified for the formation of large inlandice) in combination with mighty oceanic heat storage ( Stokes, D. P. Adam, R. E. Newell). 相似文献

Gambling by tourists occurs in many places around the world. More regions and countries are establishing casinos, regarded as attractions. How are gambling and tourism related? Why and how do casinos attract tourists? The characteristics of gambling games can be compared with the gambles of normal life, to help explain why such games are popular. Aligning that analysis with two types of tourism, wanderlust and sunlust, leads to a conclusion that the former type is not prone to gambling games. Evidence from several countries also suggests that the proximity to a political border with a neighbouring country or province that outlaws casinos can be a factor behind the success of tourist destinations offering gambling facilities for sunlust tourists. To overcome objections by local residents to proposals for establishing gambling facilities, pro-casino lobbies appear to use “tourism” as a kind of Trojan Horse, disguising the point that the major gambler market is in the local population. New Zealand is a recent case where this appears to be happening. 相似文献

In this paper, an approach is presented to analyze the stability risk of rock slopes based on a new rating system. Three factors are used to estimate the risk level of rock slopes: (1) failure probability, (2) element at risk rating, and (3) vulnerability rating. Element at risk and vulnerability ratings are both given a range from 0 to 10, and the probability of failure is varied between 0 and 1, so the risk rating ranges between 0 and 100. This risk rating can be used to determine both the quantitative and qualitative risk levels of slopes at the same time. The method is tested on the western sector of the slopes facing Songun copper plant phase III, Iran, to clarify its procedures and assess its validity. Deterministic kinematic analyses showed that the slope has a potential for circular failure. Risk assessments revealed that the risk levels of the slope in both static and pseudo-static conditions are “very low” and “high,” respectively. 相似文献

“Political-industrial ecology” has been proposed as an emerging subfield of nature-society geography. In mapping out the landscape of this subfield, this paper develops a typology of three approaches to connecting politics and industrial ecology: (1) Integrative research that incorporates social, political, policy, institutional, and/or spatial considerations into industrial ecology analyses (“politics in industrial ecology”); (2) Complementary research that couples findings or frameworks from industrial ecology with social and political research (“politics and industrial ecology”); and (3) Critical research that examine how values, norms, groups, political relations, or institutions shape the production, interpretation, and usage of industrial ecology knowledge (“politics of industrial ecology”). This broad framing of political-industrial ecology invites contributions from many social sciences, including political ecology, political geography, political economy, sociology, public policy, management, environmental history, and science and technology studies. 相似文献

Holistic understanding of estuarine and coastal environments across interacting domains with high-dimensional complexity can profitably be approached through data-centric synthesis studies. Synthesis has been defined as “the inferential process whereby new models are developed from analysis of multiple data sets to explain observed patterns across a range of time and space scales.” Examples include ecological—across ecosystem components or organization levels, spatial—across spatial scales or multiple ecosystems, and temporal—across temporal scales. Though data quantity and volume are increasingly accessible, infrastructures for data sharing, management, and integration remain fractured. Integrating heterogeneous data sets is difficult yet critical. Technological and cultural obstacles hamper finding, accessing, and integrating data to answer scientific and policy questions. To investigate synthesis within the estuarine and coastal science community, we held a workshop at a coastal and estuarine research federation conference and conducted two case studies involving synthesis science. The workshop indicated that data-centric synthesis approaches are valuable for (1) hypothesis testing, (2) baseline monitoring, (3) historical perspectives, and (4) forecasting. Case studies revealed important weaknesses in current data infrastructures and highlighted opportunities for ecological synthesis science. Here, we list requirements for a coastal and estuarine data infrastructure. We model data needs and suggest directions for moving forward. For example, we propose developing community standards, accommodating and integrating big and small data (e.g., sensor feeds and single data sets), and digitizing ‘dark data’ (inaccessible, non-curated, non-archived data potentially destroyed when researchers leave science). 相似文献
