Last April I spent three weeks in Nepal, most of the time walking up to the Annapurna Sanctuary, north of Pokhara in western Nepal. This is a popular area for trekking, with spectacular scenery; and I will try to give an impression of what can be found there, with some explanation of the geology and scenery. This is a general overview of what is on offer for the amateur geologist and dedicated walker and not a detailed field guide.  相似文献

The majority of rural communities have limited agricultural development opportunities within the hills and mountains of Nepal. While the dominant development model, which focuses on technology transfer and the evolution of commercial production systems, is effective when access to inputs and markets enables farmers to produce and trade successfully, many communities are marginalised from development opportunities by poverty and poor infrastructure. Complementary development approaches that value, conserve, develop and market agrobiodiversity could alleviate the extreme poverty where these conditions prevail as in the hills and mountains, the rural margins of Nepal. Formalised in situ approaches to agrobiodiversity conservation are in their infancy in Nepal, yet suggest that opportunities exist for a complementary agricultural development approach in the rural margins based on working with the local diversity, rather than its elimination. The obstacles of widespread poverty and inadequate infrastructure ensure that effective in situ agrobiodiversity conservation programs must provide for the needs of local people for sustainable development.  相似文献

After the changes of 1989, urban-to-rural migration in Poland and Hungary remained stable compared to rural-to-urban migration. This was connected to a growing importance of suburbanisation around major Hungarian and Polish cities. Suburban areas around these cities are attracting increasing numbers of migrants from the major cities. Pollution and higher crime rates, as well as rising living costs and increasing uncertainties make many people to decide to leave the city for the surrounding countryside. Not only upper middle-class people move to the suburbs, but also lower status people, for whom life in the big city became too difficult. Long-distance migration from the cities to the rural areas is declining. Economic problems together with low employment opportunities prevent people from making such a move. Though the overall level of urban-to-rural migration did not change too much, this article shows the rapidly increasing importance of suburbanisation. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Some of Iran’s cities, specially Tehran that is the capital city of Iran have faced sudden changes of industrialization due to political, economic and ecological considerations. There is no doubt that it is not possible to conduct a thorough investigation of the cultural structures of these cities by theoretical models and they shall be evaluated in comparative and combinational terms. Because of the consideration mentioned above, different ethnicities and groups from different cultural backgrounds have been attracted to these cities and subcultures are highly influential in socialization, acculturation, solidarity, and integration of the individuals in the society. Although, one of the problems of the industrial cities all over the world, including Tehran is migration (from towns and villages), inflexible solutions and approaches to the migration problem are not logical. In addition, recourse to the weakness of the villages and attractions of the capital can not solve the problem (as shown by the author’s experience). Therefore, it seems that creating occupational opportunities in villages and towns is one of the practical and useful ways for the survival of small towns and reduction of the migration to big cities, including Tehran.  相似文献

Since the 1990s, Ghana has been hosting refugees from neighbouring West African countries and other parts of Africa but not much information is available on their experiences in the country. The main objective of this paper therefore is to examine the experiences of the refugees using the Liberian refugees in the Buduburam Refugee Camp as a case study. Using an in-depth interview guide, 44 refugees of both sexes were interviewed through a convenient sampling procedure based on their consent and willingness to participate in the study. The study employed the structuration theory of migration to examine their experiences and the Kunz’s (Int Migr Rev 15:42–51, 1981) typology of refugees to classify the refugees. Through their own capabilities and opportunities offered by both structure and institution, some refugees were able to sustain themselves through petty trading and artisanship while others were unemployed and had to depend occasionally on their social networks for economic support. Cultural shocks, acculturation, tension and occasional quarrels with the indigenes, stigma and discrimination against refugees in schools and at health centres, inaccessibility to formal sector employment, poor security and inadequate infrastructural facilities were some of their experiences in and outside the camp. The need for proper identification of refugees for security reasons, provision of better security and adequate infrastructural facilities and skills training for refugees to engage in livelihood activities were some of the recommendations from the refugees themselves.  相似文献

South Korean immigration to Canada has increased since the East Asian economic crisis of the late 1990s. Korean immigrants in Winnipeg chose the city for many reasons: the introduction of the Provincial Nominee Program, structural changes in the home country, and individual family strategies to provide better educational opportunities for their children. This article examines how changes in the current wave of globalization, at both global and local scale, have affected the migration of Koreans to Winnipeg, Canada and how individual households chose their immigration destination. This study contributes to understanding of the less popular immigrant destinations of Canada using a multiscalar analysis that includes household level. In addition to economic purposes and children’s education, changes of life style can be an important reason for immigrant location choice. Overall, the neoliberal economy in South Korea has pushed many Koreans to move to other countries, and the globalization of the Canadian economy has pulled nomadic middle-class members from other countries.  相似文献

Foreign employment has become a global phenomenon. With the increasing commercialisation and formalisation of transnational labour migration, recruitment agencies and agents have gained importance. The paper aims to contribute to a more differentiated understanding of the role and the practices of the main actors in the middle space of migration, the brokers in the recruitment process for transnational migration. Based on empirical material from Nepal, it argues that the detected negative reputation of labour brokers is only partially justified. Besides common bad practices and fraud cases, recruiters perform important roles for the facilitation of transnational mobility and present the necessary infrastructure for labour migration. They connect people and places, establish networks and can play an important role in making migration safer. Brokers are important facilitators in supporting alternative income strategies and new livelihood options of people. At the same time they are entrepreneurs in a competitive and risky economic field, confronted with multifaceted constraints. As long as the gap between the dreams of potential migrants and the reality of marginality in Nepal remains wide, labour brokers might persist as important middlemen for global work. Thus, migration brokerage is likely to remain big business.  相似文献

Current theorising in human geography draws attention to the relational emergence of space and society, challenging ideas of difference that rely on fixed identities and emphasising the importance of the everyday in the production of social inequalities. Similarly, feminist political ecology has emphasised the role of ‘nature’ or ‘environment’ in the production of subjectivities such that ideas of gender and nature arise in relation to each other. In this paper I build from these insights to explore the ways in which the embodied performance of gender, caste and other aspects of social difference collapse the distinction between the material and the symbolic. Symbolic ideas of difference are produced and expressed through embodied interactions that are firmly material. Through this kind of conceptualisation, I hope to push forward debates in geography on nature and feminist political ecology on how to understand the intersectional emergence of subjectivities, difference and socio-natures. Importantly, it is the symbolic meanings of particular spaces, practices and bodies that are (re)produced through everyday activities including forest harvesting, agricultural work, food preparation and consumption, all of which have consequences for both ecological processes and social difference. Through the performance of everyday tasks, not only are ideas of gender, caste and social difference brought into view, but the embodied nature of difference that extends beyond the body and into the spaces of everyday life is evident. I use ethnographic evidence from rural Nepal to explore the ways in which boundaries between bodies, spaces, ecologies and symbolic meanings of difference are produced and maintained relationally through practices of work and ritual.  相似文献

Drawing on a local study on Nepal’s Terai, this paper explores the nature of livelihood exposure to shocks and stresses among rural households in two Village Development Committees in Sunsari District. The primary data are derived from a 117 household survey supplemented by 19 purposefully sampled follow-up interviews. The paper opens with a discussion of the changing nature of exposure in the global South, distinguishing between inherited vulnerability and produced precarity. We then provide background to the research site and the research methods. In the core empirical part of the paper we unravel and distinguish between the livelihood threats and opportunities faced by households in the area and use these to reflect on the nature of ’exposure’, its historical origins and contemporary (re)production. The final part of the paper uses the Nepal case to build a more general argument, proposing that if we are to understand the puzzle of continued livelihood exposure and uncertainty in the context of aggregate economic expansion we need to identify and interrogate the processes that may, at the same time, produce wealth and reduce vulnerability, while also generating precarity.  相似文献

This paper engages with contemporary debates in labour geography through its focus on: migrant workers as active agents of change; precarious employment, its complexities and consequences; and the importance of material spaces in migrant labour struggles. Since the early 2000s the South Korean government has been strengthening the institutionalised regulation of low-wage migrant workers. A key tool in this process is the Employment Permit System (EPS), in force since 2004. Under this policy migrant workers are temporary sojourners and effectively socio-politically, culturally and spatially excluded from Korean society. EPS restricts migrants’ freedom to choose or change workplaces, which renders them vulnerable to economic and social precarity. Employers use these restrictions to segregate migrant workers from co-nationals, and low-waged migrant workers often find themselves in exploitative working conditions in isolated places. This paper is based on deep ethnographic fieldwork in “Nepal Town” in Seoul and remote Nepalese workers’ accommodation. We examine how such precarious working conditions and isolation impact on workers’ active involvement in the formation and transformation of Nepal Town in Seoul. We examine the ways in which Nepal Town is a site of spatial agency and praxis for Nepalese workers and explore the potentialities of ‘reactive ethnicity’. The empirical insights provided, suggest that the regulatory migration regime for low-wage migrant workers is strongly linked with new formations of material landscapes of connection, mobility, freedom and safe space. Such space production enables migrant workers to perform agency and employ tactics of resistance in order to create spaces of possibility.  相似文献

Human migration may negatively impact biodiversity and is expected to increase in future, yet the phenomenon remains poorly understood by conservation managers. We conducted a mixed-methods investigation of a contemporary migration of traditional fishers in western Madagascar, a country which has been expanding its protected area system through the establishment of both strict and multiple-use sites, and critically evaluate different models of marine protected area in light of our findings. Interviews with fishers in major destination areas revealed that most migrants come from southwest Madagascar, use non-motorised vessels, and principally target sharks and sea cucumbers. Drivers of the migration include both push and pull factors (i.e. declining resource availability in areas of origin and the continued availability of lucrative resources for export to China). Traditional fisher migrants cause limited social conflict with residents and a number of environmental problems in destination areas: however artisanal fishers with motorised vessels probably represent a greater threat to marine resources than migrants, due to their greater harvesting capacity. We suggest that multiple-use arrangements may be more appropriate than strict protected areas in both source and destination areas, because they integrate the interests of migrants rather than marginalising them: however seascape-scale management provides the best approach for managing the threats and opportunities provided by the migration at the appropriate scale.  相似文献

Losses due to natural disasters induce rural–urban migration throughout the world. It is also a major driver of population influx in Dhaka city, the capital of one of the most disaster-affected countries in the world, Bangladesh. While the relationship between natural disasters and migration is evident, the magnitude of household-level losses inducing rural–urban migration has not been widely discussed. This paper approaches this issue based on an empirical study. Using appropriate sampling procedure, a total of 407 households in Dhaka statistical metropolitan area were interviewed. This research finds out that 18.43% of rural–urban migrants in Dhaka city are disaster induced. A sharp drop in income immediately after the disaster is the predominant reason behind their migration. The river bank erosion-affected migrants encountered as high as 89% drop in income, whereas the flood-affected migrants experienced 70% drop. This article identifies five post-disaster components that ultimately determine migration. To conclude, the paper offers several approaches to minimize mass rural out-migration.

The Himalayas are one of very active seismic regions in the world where devastating earthquakes of 1803 Bihar–Nepal, 1897 Shillong, 1905 Kangra, 1934 Bihar–Nepal, 1950 Assam and 2011 Sikkim were reported. Several researchers highlighted central seismic gap based on the stress accumulation in central part of Himalaya and the non-occurrence of earthquake between 1905 Kangra and 1934 Bihar–Nepal. The region has potential of producing great seismic event in the near future. As a result of this seismic gap, all regions which fall adjacent to the active Himalayan region are under high possible seismic hazard due to future earthquakes in the Himalayan region. In this study, the study area of the Lucknow urban centre which lies within 350 km from the central seismic gap has been considered for detailed assessment of seismic hazard. The city of Lucknow also lies close to Lucknow–Faizabad fault having a seismic gap of 350 years. Considering the possible seismic gap in the Himalayan region and also the seismic gap in Lucknow–Faizabad fault, the seismic hazard of Lucknow has been studied based on deterministic and the probabilistic seismic hazard analysis. Results obtained show that the northern and western parts of Lucknow are found to have a peak ground acceleration of 0.11–0.13 g, which is 1.6- to 2.0-fold higher than the seismic hazard compared to the other parts of Lucknow.  相似文献

ABSTRACT

Mylonitic orthogneisses in the Kathmandu area, central Nepal have been investigated using whole-rock and mineral chemistry, Rb-Sr isotopes, and zircon U-Pb age dating. Zircon REE patterns determined from orthogneisses are characterized by enriched HREE patterns and the prominent Eu anomalies, consistent with a magmatic origin. The U-Pb zircon age dating and Ti-in-zircon thermometry revealed crystallization took place ca. 1.74 Ga at temperatures of 705–765℃; typical of felsic magmatism in the crust. Whole-rock data from most orthogneisses in this study and from similar rocks in previous studies span the ‘syn-collisional’ and ‘post-collisional’ fields on various tectonic discrimination diagrams, while some data also plot in rift-related magmatism fields. The peraluminous compositions, very high Sr isotopic ratios (0.865–3.585) and high Th and U concentrations for all orthogneisses in this study indicate that mylonitic orthogneisses are largely of S-type crustal origins. The new data presented herein, combined with that of previous studies, outline at least two Palaeoproterozoic magmatic episodes: 1) ca. 1.92–1.90 Ga rift-related magmatism derived from mantle melting and 2) 1.84–1.74 Ga crustal melting, resulting from burial of the Indian basement during thermal subsidence after rifting. This two-stage Palaeoproterozoic magmatism in Nepal occurred along the northern passive margin of the Indian basement during and/or after the breakup of the Columbia supercontinent.  相似文献

Previous research suggests that entrepreneurship can provide ethnic minorities a springboard for economic advancement and social integration. However, self-employment rates vary significantly among ethnic groups, between men and women, and in different places. The prevailing literature suggests that personal characteristics, including human capital attributes, ethnic networking, institutional regulations, societal structures and discrimination, all contribute to the differential ethnic entrepreneurship rates. However, very few recent studies have analyzed how different urban socio-economic contexts influence this process. Using the 2000 Public Usable Microdata Samples (PUMS), this study examines how Hispanic entrepreneurs perform in three different metropolitan areas in the US South. The results show that the ethnic diversity, history of immigration, and the economic structure in each local area have provided different opportunities and challenges for Hispanics to start up and maintain their own businesses. This study suggests that the process of economic incorporation of ethnic minorities and immigrants depends significantly on the institutional capacity and social, cultural and political resources of local communities.  相似文献

1. Introduction In recent years, growing attention has been focused on diapirs because of their significance to hydrocarbon accumulation in basins (Barber & Brown, 1988; Martin Hovland et al., 1989; Law et al., 1989; Collier et al., 1990; Lewis et al., 1994; Carmelo Monaco et al., 1996; Hieke et al., 1996; Hieke et al., 1996; Lewis et al., 1996; Limonov et al., 1996; Gallardo & Blackwell, 1999).

Causes of large-scale landslides in the Lesser Himalaya of central Nepal   总被引：1，自引：0，他引：1  
Geologically and tectonically active Himalayan Range is characterized by highly elevated mountains and deep river valleys. Because of steep mountain slopes, and dynamic geological conditions, large-scale landslides are very common in Lesser and Higher Himalayan zones of Nepal Himalaya. Slopes along the major highways of central Nepal namely Prithvi Highway, Narayangadh-Mugling Road and Tribhuvan Highway are considered in this study of large-scale landslides. Geologically, the highways in consideration pass through crushed and jointed Kathmandu Nappe affected by numerous faults and folds. The relict large-scale landslides have been contributing to debris flows and slides along the highways. Most of the slope failures are mainly bechanced in geological formations consisting phyllite, schist and gneiss. Laboratory test on the soil samples collected from the failure zones and field investigation suggested significant hydrothermal alteration in the area. The substantial hydrothermal alteration in the Lesser Himalaya during advancement of the Main Central Thrust (MCT) and thereby clay mineralization in sliding zones of large-scale landslide are the main causes of large-scale landslides in the highways of central Nepal. This research also suggests that large-scale landslides are the major cause of slope failure during monsoon in the Lesser Himalaya of Nepal. Similarly, hydrothermal alteration is also significant in failure zone of the large-scale landslides. For the sustainable road maintenance in Nepal, it is of utmost importance to study the nature of sliding zones of large-scale landslides along the highways and their role to cause debris flows and slides during monsoon period.  相似文献

Malaysia is emerging as one of the most rapidly developing newly industrialized countries in the 1980s, mainly because it has pursued a strategy that is based on highly capital-intensive and export-oriented types of industries, financed by foreign capital and supported by a wide range of fiscal incentives. There has been, however, very little concern for the types and range of employment opportunities available. Based on unskilled labour, low wages and slow rates of employment absorption, this form of “industrialization-by-invitation” will in turn speed up processes or urbanization through rural-urban migration and create socio-economic problems of large city growth in the country.  相似文献
