1955~1956年,上海市经历了新中国成立以来首次大规模的城市人口疏散。为了应对日益严峻的城市人口压力,上海市动员了大批外来农民回原籍生产,并组织城市失业人口前往江西等地参加垦荒建设,期间共有50余万城市人口被疏散。从人口形势与粮食供给关系来看,城市粮食供应困难是导致这次城市人口疏散的重要原因。这一事件影响到此后的国家政策走向。  相似文献

This article describes the conditions for the development of four industrial clusters and the mechanisms of their integration in the regional economy. The case studies are the aerospace and apparel clusters in Montreal, and the agri‐food and marine science and technology clusters in the Lower St. Lawrence region. Clusters are defined as arrangements of businesses, government actors, public authorities, and local intermediary organizations in a local area. However, the study shows that clusters are based on actors and processes operating at different scales, from the local to the global. It also shows the importance of the sectoral leadership acknowledged by the different stakeholders.  相似文献

Abstract: Tracing the commodity chain of broccoli from Nashville, Tennessee supermarkets to Maya farmers in highland Guatemala, this paper examines relations of desire and political economic power. We argue that the global broccoli trade is shot through with desires—desires of Western consumers to eat healthy foods as well as desires for Maya farmers to get ahead economically. Such desires simultaneously subvert and sustain the hegemonic constellations that anchor crucial nodes in the international broccoli trade.  相似文献

This paper forges an agenda for researching geographies of infants. Scholars have tended to overlook the everyday geographies of very young children. However, outside of geography, infancy is seen as a specifically dynamic period of life, and is subject to sustained research and policy intervention. In particular, early childhood is viewed as a key point in which to intervene to transform enduring, interconnected, societal, educational, and health-based inequalities. Food and feeding are seen as critical both to the health of infants now and of the children and adults they become . However, much policy and research under-theorizes the importance of socio-spatial contexts and the subjectivity/agency of infants. There is, then, an urgent need for geographers to put infants onto the agenda, to inform and challenge these dominant accounts. Researching with infants necessitates not just critiquing modern, liberal notions of an autonomous subject/agent, but developing a new way of understanding subjectivity and agency. Drawing upon Lupton’s (2013) notion of infant–carer interembodiment, I suggest a way forward with reference to the material geographies of infant feeding.  相似文献

Domestic commercial land acquisition is a recent phenomenon in Nepal; it is rapidly expanding and increasingly occupying productive agricultural land for real estate and other non-agricultural commercial purposes. This paper analyses the present situation and the implications of domestic land acquisition, and identifies actors and forms of land deals and associated conflicts. The study was conducted in Kathmandu Valley (27° 32′ 13″ N to 27° 49′ 10″ N and 85° 11′ 31″ E to 85° 31′ 38″ E) and Chitwan District (83°54′ 45″ to 84°48′15″ E and 27°21′45″ to 27°52′ 30″ N), the areas of Nepal most affected by domestic land acquisition. In the absence of statistical material, purposive sampling was used to identify households for a survey of 208 respondents; this was complemented by qualitative research and a review of media and other documents. Respondents confirmed that land acquisition is increasing at a very rapid rate and is driven by a nexus of politicians, land brokers and real-estate actors, and that it has caused not only food insecurity but also numerous conflicts between local people and the land deal actors. Existing policies and legislations were found to be inadequate to address the challenges brought about by the domestic land acquisition process in Nepal.  相似文献

This paper reviews the signature characteristics of extant Second World War German army munitions storage landscapes in forested areas of north-west Europe with particular reference to sites in north-west France and the Netherlands. Archaeological survey, aerial photographs and documentary archives show the geography of munitions sites exhibit a regulated pattern of bunker disposition and spacing that is adapted to local road configurations and terrain. Non-hardened bunkers form the predominant feature in munitions depots and conform to a five-/six-fold typology defined by non-invasive survey and excavated examples from the Netherlands. The typology reflects an evolution of storage protocols towards all-round protection from the effects of weather and blast, but also reveals variation in size, structural characteristics and function that poses questions for further study. It is anticipated that these results will be of diagnostic value in future Second World War conflict archaeological survey of German military support structures in formerly occupied territories.  相似文献

Fresh food markets have been a fixture of the social and economic landscape of urban and rural PNG since colonial times. They were often the first points of engagement with the market economy, especially for women, who as small‐scale producers, sold surplus produce from their food gardens located on communally‐owned land. Although local food markets have remained an important livelihood for women, the later adoption and expansion of perennial export cash crops like coffee and cocoa overshadowed food production for local markets as men dominated export crop production on land alienated from communal ownership for decades or permanently. New forms of social relations of production and more exclusive forms of land tenure emerged to accommodate export crop production that were very different from those governing the production and marketing of fresh food. Market values and a trend towards individualisation of production with less capacity to mobilise labour through reciprocal labour exchange networks have characterised export crop production. With the income benefits captured largely by men, women began redirecting their labour to fresh food production where they were able to exercise more control of production and income while still mobilising labour through indigenous labour exchange arrangements. Attempts by men to appropriate the income of women and sons’ labour in export cropping were greater during flush periods when income levels were high, and they were less likely to attempt to appropriate this income in low crop periods when incomes were lower. However, with the recent emergence of female entrepreneurers earning relatively large sums of money in large‐scale, profit‐driven vegetable production, the moral frameworks governing food production are coming to resemble those governing export crops, and making labour more difficult to mobilise. Despite women being key players in these changes, we argue there is an emerging risk that men will attempt to assert control over this income or move into vegetable production themselves and possibly marginalise women in the process.  相似文献

This paper seeks to extend geographic thinking on the changing constitution of the UK welfare state, suggesting the need to supplement ideas of the “shadow state” with an analysis of the blurring of the bureaucratic practices through which welfare is now delivered by public, private and third sector providers alike. Focusing on the growing convergence of the bureaucratic practices of benefits officials and food bank organisations, we interrogate the production of moral distance that characterise both. We reveal the ideological values embedded in voucher and referral systems used by many food banks, and the ways in which these systems further stigmatise and exclude people in need of support. Contrasting these practices with those of a variety of “ethical insurgents”, we suggest that food banks are sites of both the further cementing and of challenge to the injustices of Britain's new welfare apparatus.  相似文献

Food security remains a critical global issue, made more difficult because of the rising world population, climate challenges affecting food production and a focus on market-based solutions that undermine subsistence production in vulnerable rural areas. Particularly affected are countries across Asia where poverty, hunger and malnourishment affect a significant proportion of the population. Drawing on Sen’s entitlement theory, we argue that a shift in focus from national food production to intra-household food access enables a critical reflection on consumption smoothing strategies adopted at this level. In particular, we draw attention to the tendency for women and girls to eat less as an intra-household adaptation strategy. We present findings from our research in rural areas of Bangladesh and note that adaptation strategies adopted by households in response to food insecurity. We note that strategies designed to address food insecurity must include gender mainstreaming to ensure that women and girls are not taking a disproportionate responsibility for intra-household food security.  相似文献

Abstract

The scarab impression on the rim of a Middle Bronze II storage jar is the first of its kind to be discovered in Israel. The pattern on the impression appears on scarabs of the period. The unusual location of the impression may point to a special content of the jar, or alternatively to the owner of this pot. Once the context of the storage jar rim is studied, it may shed some light on the possible association of this jar with the scarab impression on its rim.  相似文献
