International labour migration programs provide a vulnerable workforce that services various sectors in developed economies. The agriculture sector is one arena in which the employment of migrant workers has become more pervasive. Annually, approximately 30,000 workers are employed in the Canadian agriculture sector through the Seasonal Agricultural Workers Program (SAWP). In this paper, I focus on the SAWP workers in tobacco farming, and investigate the ways that labour control is achieved on two small‐scale farms. I draw upon original empirical evidence from interviews with three Mexican and nine Jamaican workers, two union representatives, and two farm owners in South‐Western Ontario, Canada. My findings show that various factors at multiple scales shape the labour control regime and significantly advantage farm owners over workers. Based on my findings, I argue that the labour control regime is conditioned exogenously by multi‐scalar factors and generated endogenously at the point of production.  相似文献

This study examines the remains of an agricultural complex found in the Yavneh coastal dunefield, central Israel. Known as a plot-and-berm agroecosystem, the complex consisted of earthworks in a crisscross pattern of sand berms and sunken agricultural plots that were used for groundwater harvesting. The plots, which provided easy access to the high groundwater table and the berms around them, are overlaid by a gray sand unit covered by pottery sherds and artifacts. This gray sand is more fertile than the underlying sand, suggesting refuse enrichment. Artifactual similarity of the finds to those of inland (Tel) Yavneh suggests that Yavneh was the main source for the refuse additive. Based on artifacts and OSL ages it seems that this agroecosystem was active during the 10th to early 12th centuries a.d. The agroecosystem demonstrates an early example of an Early Islamic agrotechnological attempt in marginal and sandy regions of the Mediterranean basin.  相似文献

In this paper, we present a model of prehistoric southwestern Colorado maize productivity. The model is based on a tree-ring reconstruction of water-year precipitation for Mesa Verde for the period A.D. 480 to 2011. Correlation of historic Mesa Verde precipitation with historic precipitation at 11 other weather stations enabled the construction of an elevation-dependent precipitation function. Prehistoric water-year precipitation values for Mesa Verde together with the elevation-dependent precipitation function allowed construction of the elevation of southwest Colorado precipitation contours for each year since A.D. 480, including the 30-cm contour, which represents the minimum amount of precipitation necessary for the production of maize and the 50-cm contour, which represents the optimum amount of precipitation necessary for the production of maize. In this paper, calculations of prehistoric maize productivity and field life for any specific elevation are also demonstrated. These calculations were performed using organic nitrogen measurements made on seven southwestern Colorado soil groups together with values of reconstructed water-year precipitation and estimations of the organic nitrogen mineralization rate.  相似文献

In the political and medial discourse of the 1930s the contract-work system (stat/ar/systemet) was depicted as a relic of pre-modern society and contract-workers (statare) as the highly exploited lower class with no legal rights, low incomes, miserable housing conditions and a chaotic family life. This picture has dominated Swedish social history ever since, and the main argument of this article is that it has to be modified. With regard to the material standard of living, for example, employment terms, working conditions, wage levels and housing conditions, contract-workers were no worse off than other worker groups in the countryside. On the contrary, the contract-work system had its own rationality and advantages. It made it possible for young couples without land or a croft to marry and establish their own household since housing was included in the payment, and the yearly employment and large proportion of in-kind payments provided income security. However, the political discourse of the 20th century was based on the growing importance of the town and industry. The more regulated employment conditions, higher wages and better housing for industrial and urban workers became the yardstick by which the contract-workers' situation was judged. Agriculture was an economic sector in decline and the contract-work system appeared to be outdated. The abolition of the contract-work system in 1945 was definitive confirmation of the victory of modernity.  相似文献

The article discusses the thinking of Mario Einaudi in relation to the ambitious measures with which the Italian government sought to move towards land reform in the immediate post–war period. Einaudi, an intellectual and academic, was by birth Italian but moved to the United States during the Fascist period. Like his father Luigi, the noted economist, he was convinced of the need to stimulate the free market in land in order to increase productivity and modernise cultivation methods; in his writings he repeatedly sought to develop a plan of action that would facilitate collaboration between Rome and Washington in this field, identifying the Tennessee Valley Authority approach as especially suited to the Italian case. However, while his ideas achieved a good public airing, they had a limited impact: on the political front, Cold War priorities pushed Italian and US Marshall Plan experts more towards the redistribution of landownership than towards stimulating the productivity of agricultural businesses, in the attempt to rapidly build a consensus behind the government; and on the cultural front, at the end of the 1950s the issue of backwardness in the rural South started to be interpreted in terms of cultural and social anthropology, an approach which did not directly relate to the development of political programmes.  相似文献

管窥张闻天从个体农业经新民主主义走向社会主义的构想   总被引:1,自引:0,他引:1  
张闻天关于农村合作经济的思想是他为我们党留下的精神遗产的一部分。张闻天所说的供销合作社与生产合作社 ,是以私有制为基础的各种类型的劳动互助组织 ,发展供销合作社与劳动互助组织 ,为农业集体化准备条件 ,经过长期的说服教育 ,在经济上必须实行一条无产阶级的领导路线 ,以最终引导农民走向社会主义。搞新民主主义建设 ,张闻天提出发展合作社的道路 ,是从供销合作到生产合作。在这条道路中 ,发展农村供销合作社占有重要的地位和作用。供销合作社是把小生产者与国营经济结合起来的桥梁和纽带 ,担负着改造小生产者社会制度的历史任务。需要坚持自愿互利原则 ,反对强迫命令 ;保护农民的私有权 ;正确处理和资本主义的关系  相似文献

We describe a preliminary survey of a relatively unknown part of the eastern Himalayas: northwestern Sichuan. This survey revealed that three phases of occupation are represented across the landscape. Large settlements with dense remains characterize the landscape during the Neolithic (3400–2000 cal b.c.). Following a hiatus in occupation, stone-cist graves characterize the region during the Bronze Age (1450–800 cal b.c.). The lack of settlement remains from this period indicates that mobile pastoralism increased in importance. Finally, between a.d. 500 and 1500, dense scatters of ceramics over a wide altitudinal range correspond to a fragmentation in Tibetan history, when local warlords established themselves in the region. While some changes in occupation and subsistence practices are linked to climate change, others relate to changes in political power. We argue that further survey work is needed to expand our understanding of past land use and the development of pastoralist practices.  相似文献

Recent literature has pointed to the role of urban agriculture in self‐empowerment and learning, and in constituting ways to achieve food justice. Building on this work the paper looks at the potential and constraints for overcoming the residual and contingent status of urban agriculture. The first part of the paper aims to expand traditional class/race/ethnicity discussions and to reflect on global, cultural, procedural, capability, distributional and socio‐environmental forms of injustice that unfold in the different stages of urban food production. The second part reflects on how to bring forward food justice and build a politics of engagement, capability and empowerment. Three interlinked strategies for action are presented: (1) enhancing the reflexivity and cohesion of the urban food movement by articulating a challenge to neoliberal urbanism; (2) converging urban and agrarian food justice struggles by shaping urban agroecology; and (3) regaining control over social reproduction by engaging with food commoning.  相似文献
