Governing people on the move in a warming world: Framing climate change migration and the UNFCCC Task Force on Displacement     

《Global Environmental Change》2022

Different ways of framing the nexus between climate change and migration have been advanced in academic, advocacy and policy circles. Some understand it as a state-security issue, some take a protection (or human security) approach and yet others portray migration as an adaptation or climate risk management strategy. Yet we have little insight into how these different understandings of the ‘problem’ of climate change-related migration are beginning to shape the emergence of global governance in the climate regime. Through a focus on the UNFCCC Task Force on Displacement we argue that these different framings of climate change migration shape how actors understand the appropriate role of the TFD, including the substantive scope of its mandate; its operational priorities; the nature of its outputs and where it should be situated in the institutional architecture. We show that understanding the different framings of the nexus between climate change and migration – and how these framings are contested within the UNFCCC – can help to account for institutional development in this area of climate governance.  相似文献   

Imagining global work: Producing understandings of difference in ‘easy Asia’     

《Geoforum》2016

In this paper, I advance debates that argue that we need to reconceptualise global work from a mobilities perspective by looking how the representation of movement connects with the experience of movement. By looking at the imaginative geographies of Singapore for the British corporate expatriate, I explore how the qualitative representation of place is changing within managerial discourses from a hardship to an opportunity. In doing so, the paper argues that we need to combine understandings of the global economic flows that move some transnational migrants with their everyday lived experiences in order to explore what qualitatively makes work global. This allows us to highlight the multiplicity of ways in which transnational migrants can be understood rather than trying to impose singularity.  相似文献   

Young people navigating political engagement through post-war instability and mobility: A case from rural Nepal     

《Geoforum》2016

The everyday politics of rural young people who live in post-war settings in the Global South is poorly explored. In the aftermath of a recent civil war in Nepal (1996–2006), villages have been operating without elected bodies, and poorly functioning local governance has been concentrated around party patronage networks and community development. In the lives of many young people, the aspirations and practices of educational and labour mobility have been dominant. Based on fieldwork carried out in the Panchthar District, this article discusses how ordinary young people nevertheless engage in different political dimensions. Guiding the analysis through the narratives of four young men and women, I have accentuated how the tension between socio-political situatedness and young people’s life strategies shapes the versatility of their political engagement. How do those who did not become political activists balance their daily lives, mobility and household obligations with involvement in party and local development politics? By exploring their motivations and engagement, I come to two conclusions. Firstly, young men navigate party politics by juggling the legacy of patronage and rejecting parties, as well as by involving themselves in disruptive events and seeking personal benefit from them. Secondly, young men and women negotiate their political motivations in community development politics primarily through household dynamics adjusted to their mobile lifestyle.  相似文献

Defining geographical mobility: Perspectives from higher education     

《Geoforum》2017

Context is generally overlooked when selecting measures to define geographical mobility in mobility and migration research. This paper contributes to a discussion on the importance of context when defining geographical mobility and draws on examples from higher education in Sweden. Using binary logistic regression, statistical outcomes are compared when different measures of mobility to and mobility from higher education are employed. The measures produce different statistical outcomes, and these differences are illuminated when comparing results of common measures of mobility (e.g. crossing administrative boundaries or moving a certain distance) against two measures constructed specifically for Swedish higher education-related mobility. The results indicate that using municipality boundaries for measuring mobility in the Swedish higher education context is particularly inappropriate because the measure does not differentiate commuters from movers. This challenge surfaces because mobility must be determined in relation to the locations of students’ higher education institutions since administratively registered moves are unreliable in the educational context. These findings emphasize the importance of considering the geographical locations and characteristics of higher education institutions in addition to feasible commuting possibilities in research on higher education-related mobility. The two measures developed for the Swedish higher education context are identified as most appropriate because they center on the geographical distribution of higher education, and this distribution is perceived as having an important role in influencing mobility in this context. Consequently, this study accentuates the need for considering the geographical arrangement of resources (e.g. schools, hospitals) relevant to the context under investigation when determining measures to define mobility.  相似文献   

Distribution and Chemical Forms of Heavy Metals in the Flood 1997 Sediments of the Upper and Middle Odra River and its Tributarie:, Poland     

E. Helios Rybicka  M. Struebo&#x;ska 《洁净——土壤、空气、水》1999,27(5):331-337

At the beginning of August 1997, 72 samples of flood sediments were taken along the Upper and Middle Odra river and its tributaries. The concentrations of Zn, Pb, Cu, Cd, Co, Ni, Cr, Mn, and Fe in the bulk samples and in the <20 μm fraction were determined by AAS method. The contents of metals vary in wide ranges and are significantly higher in the <20 μm fraction of sediments. The range concentrations vary as following: Zn 274...3 656 mg/kg, Pb 79...1 773 mg/kg, Cd 1.7...11.8 mg/kg, Cu 38...2 244 mg/kg, Cr 14...384 mg/kg, Co 4...73 mg/kg, Hg 0.2...3.9 mg/kg, Mn 214...6 972 mg/kg, and Fe 1.5...16.3 %. The highest amount of the metals was found in the Wrocław and Głogów regions. The mobile (exchangeable and carbonatic fractions) portions of metals reached up to 50 % of Zn, 40 % of Pb and Cu and 60 % of Mn.  相似文献   

Towards an integrated science of movement: converging research on animal movement ecology and human mobility science     

Harvey J. Miller  Somayeh Dodge  Jennifer Miller  Gil Bohrer 《International journal of geographical information science》2019,33(5):855-876

There is long-standing scientific interest in understanding purposeful movement by animals and humans. Traditionally, collecting data on individual moving entities was difficult and time-consuming, limiting scientific progress. The growth of location-aware and other geospatial technologies for capturing, managing and analyzing moving objects data are shattering these limitations, leading to revolutions in animal movement ecology and human mobility science. Despite parallel transitions towards massive individual-level data collected automatically via sensors, there is little scientific cross-fertilization across the animal and human divide. There are potential synergies from converging these separate domains towards an integrated science of movement. This paper discusses the data-driven revolutions in the animal movement ecology and human mobility science, their contrasting worldviews and, as examples of complementarity, transdisciplinary questions that span both fields. We also identify research challenges that should be met to develop an integrated science of movement trajectories.  相似文献   

Abschätzung und Beeinflussbarkeit der Arsenmobilität in kontaminierten Böden     

Franka Dankwarth  Joachim Gerth 《洁净——土壤、空气、水》2002,30(1):41-48

Assessment and Modification of Arsenic Mobility in Contaminated Soil Arsenic concentration in the seepage of contaminated soils of an old tannery site is assessed using batch and column experiments. The effect of reducing conditions, pH, and ionic strength is also investigated. The iron oxide rich subsoil (C‐horizon) is the main source of groundwater pollution with arsenic. In this horizon, mobilization can increase as a result of reducing conditions upon periodical water saturation. Therefore, the potentially mobile arsenic is determined by a reductive dissolution of the poorly crystalline iron oxide fraction using 0.1 M ascorbic acid. Arsenic concentration can be reduced from 100 μg/L to below 20 μg/L by an increase of ionic strength (e.g. by a 0.01 M CaCl₂ solution). Arsenic contaminated soils should be limed regularly in order to maintain the highest possible calcium concentration in the soil solution.  相似文献

Urban structures and daily mobility patterns in a city of long distances—the case of Muscat/Oman     

Maike Didero  Sonja Nebel  Carmella Pfaffenbach 《Singapore journal of tropical geography》2019,40(3):361-386

Population growth, urban sprawl and a high degree of car dependency as well as slowly rising petrol prices contribute towards increasing challenges for everyday urban mobility in Muscat, Oman. Until now, only a few empirical studies have dealt with urban mobility in Oman. Therefore, this article draws mainly on our own empirical findings to answer the following questions: What do daily and weekly mobility patterns look like in Muscat? How do these practices differ depending on the social position of the household, i.e. their nationality, income and education? Which interdependent effects can be discerned between everyday mobility practices and the fragmented and segregated urban structures? Since our research questions focus on the interrelations between urban structures and individual mobility, we chose a mixed‐methods approach including methods derived both from social and spatial research. This article in particular draws on our quantitative survey covering 850 households and extensive mappings of three selected case study areas and secondary data analysis.  相似文献
