An American geographer and noted international authority on water management problems in Russia and Central Asia presents an account of an expedition, in late 2005 (under the sponsorship of the National Geographic Society) to Kazakhstan and Uzbekistan, focused on the Aral Sea. The steadily drying inland sea, with a surface area of 67,500 km2 in 1960, had split into two parts and shrunk to 17,380 km2 in 2006. The paper provides an up-to-date overview of the crisis and presents an optimistic scenario of the sea's future, noting development of economic activities (particularly fisheries) in its surrounding settlements.

The United Nations' (UN) World Population Prospects are perhaps the most widely used population projections in both academic and policy discourses. In this short research note, we examine six advanced Asian economies, and compare the fertility assumptions used by the UN with those derived from local statistical offices (LSOs). We identify a significant divergence between them. When translated into total projected population size of younger age groups (0–14 years), the use of the UN rather than the LSO ‘medium’ projection can increase the total projected population size by up to 50% by 2040.  相似文献

ABSTRACT

We analyse a nationally representative data set from India for the year 2013 in order to provide evidence on how short-term migration is affected by household ownership of land and participation in agricultural activities. We estimate a recursive-bivariate-probit model recognising the simultaneity between short-term migration and the decision to operate the land. The results of the likelihood ratio test imply that it would be incorrect to ignore this simultaneity. Households with less than 1?ha of land and those leasing out land are more likely to have a short-term migrant. Households leaving their land fallow, a common occurrence in South Asia, are also more likely to have a short-term migrant. Moreover, the choice of crops and livestock farming has a significant role to play in the migration decision. Current initiatives to increase coverage of irrigation and facilitate access to formal finance could improve the livelihoods of small and marginal farmers, thereby reducing the probability of distress-related short-term migration.  相似文献

In contrast to East and South-east Asia, changes in marriage patterns have played a small role in reducing fertility in South Asia. While age at marriage for women has risen, it remains early, with the exception of Sri Lanka, and change has been slow. Except in Sri Lanka, the region has shown few signs that there will be a sizable population that will never marry. South Asia's marriage patterns reflect its cultural context and lesser socio-economic change but their precise effect is not simple or always predictable. The paper examines these issues in Bangladesh, where age at marriage is very early, and Sri Lanka, where it is much later. The study areas, Dhaka city and south-western Sri Lanka, are ones of great economic and social change. A particular examination is made of the way in which changes in the arrangement of marriage affect age at marriage.  相似文献

International migration between Asia and Australia has undergone profound change in the last two decades. This paper outlines the major changes which have occurred in this movement. The proportion of Australia's resident population born in Asia has increased from 1.1 % in 1976 to 5.5 % in 2001. Asians now make up more than a third of new settlers to Australia but there has been an increased diversity in the flow of Asian settlers to Australia as well as the substantial increase in numbers. Australian international migration has entered a new era since the mid‐1990s with a greatly increased flow of temporary workers to Australia. The inflow of these workers is less dominated by Asia‐born people than is the permanent flow except for student migration. There is also an increasing flow of movers from Australia to Asia. Much current knowledge and research remain focused on Asian permanent settlement in Australia. While this is important and worthwhile, there is a need to broaden the work to encompass the full range of population movements between Asia and Australia if the impact of international migration is to be adequately assessed.  相似文献

The appearance of rich and diverse funerary practices is one of the hallmarks of the Late Epipalaeolithic Natufian in the Levant. Numerous burials at a number of sites excavated mostly in the Mediterranean zone of the southern Levant have fed into the interpretation of the Natufian as a sedentary society of complex hunter-gatherers. Here, we report on the human remains recovered from Shubayqa 1, a well-dated early to late Natufian site in northeast Jordan. The majority of the minimum of 23 individuals that are represented are perinates and infants, which represents an atypical population profile. Ground stone artifacts and traces of colorants are associated with some of these individuals, providing a rare insight into funerary treatment of subadults in Natufian contexts. We interpret the Shubayqa 1 evidence in the light of current and ongoing debates concerning Natufian burial practices and the issue of social complexity.  相似文献

Abstract

The archaeological record in mainland Southeast Asia from ca. 2000 b.c. to the formation of early states in the mid-first millennium a.d. is built on excavations in mounded settlements that incorporate habitation, industrial, and mortuary remains. For most sites, formation processes are not readily identified. have presented a new view of the social organization of the Southeast Asian “metal age” based on a reinterpretation of mortuary and settlement data, founded on their premise that the dead were interred in, under, or in conjunction with domestic residences rather than dedicated cemeteries. They argue that such house societies were instruments for remarkably long-term occupation of individual settlements by heterarchic, non-violent supravillage affiliative social groupings. A detailed examination of the evidence for such residential burial suggests a lack of convincing evidence until the Iron Age. Moreover, new dating programs have shortened the prehistoric sequence, leading to more rapid and intense social changes than hitherto suspected.  相似文献

ABSTRACT

Imitations of famous Dutch wall maps originally produced in Amsterdam by F. de Wit and W. J. Blaeu have recently been rediscovered in Italy. In Bologna, in the archive of Opera Pia dei Poveri Vergognosi, is a set of Blaeu's four wall maps of the continents, engraved on new plates by Pietro Todeschi and published by Giuseppe Longhi. The value of the discovery lies in the completeness of the exemplars, which also bear the publisher's imprint and date of publication, hitherto unknown: Europe 1677; Africa 1678; Asia 1679; America 1679/1680(?). An undated version of de Wit's world wall map, also published by Longhi, has come to light in the same archive. A copy of the same map, this time published by Giovanni Giacomo de' Rossi in Rome in 1675, was then found in Modena in the Seminario Metropolitano. Comparison of the two copies has provided a date for Longhi's undated issue; Longhi's map came after de' Rossi's, that is after 1675.  相似文献

This study examines the linkages which connect Communism, heritage and tourism with reference to selected East Asian states which are governed by Communist regimes or have recent experience of Communist rule. Aspects of the heritage of Communism are seen to be of interest to tourists, but related visitor attractions also have a wider social and political significance and illustrate how tourism can be employed as a hegemonic tool and propaganda vehicle. Heritage, including that of Communism itself, thus serves as economic, social and political capital within a Communist context where the defining characteristics of government give rise to a distinctive relationship between political systems, heritage and tourism.  相似文献

俄罗斯的亚太战略与政策探析   总被引:1,自引:0,他引:1  
于国政 《人文地理》2001,16(2):26-30
俄罗斯作为苏联解体后的当然继承国,成为当今世界政治经济格局多极化发展趋势中重要的一极。目前俄罗斯承袭了苏联后期的亚太战略,并在某种程度上使其有所发展。本文在分析苏联后期实施亚太战略与政策的基础上,着重探讨了俄罗斯目前实施亚太政治经济战略的新东方政策与措施,并对其远东同亚太各国的经济联系的近期态势进行了实证分析;论述了中俄关系对实施其亚太战略的重要性;指出中俄建立面向21世纪的战略协作伙伴关系完全符合两国各自的地缘经济利益。  相似文献
