Harvesting different species as foods or raw materials calls for differing skills depending on the species being harvested and the circumstances under which they are being taken. In some situations and for some species, the tactics used are mainly behavioral—that is, people adjust, or adapt, their own actions to fit the behavior and circumstances of the species they are taking. Under other circumstances and for other species, the skills and tactics used may call for greater environmental preparation or manipulation. Therefore, instead of trying to distinguish people today and in the past as either foragers or farmers, it makes sense to define human subsistence behavior as an interactive matrix of species and harvesting tactics, that is, as a provisions spreadsheet. 相似文献

The field system of the Wadi Faynan in southern Jordan was fed by an ancient combination irrigation system that incorporated runoff farming and diversion irrigation techniques. The hydraulic characteristics of this system were most probably designed to take advantage of the confluence of three tributary streams. A theoretical model of discharge produced by runoff is based on contemporary ground conditions and historic climate reconstructions. The design principles of the main hydraulic features are examined and velocity and discharge measurements in principal conveyance irrigation channels are reconstructed. The design of this hydraulic system took into account the environmental constraints and opportunities of the area and maximized different sources of water in the catchment using various techniques of water collection. 相似文献

The Romanian dairy-farming sector is marked by subsistence and semi-subsistence farms. Through consolidation in the retail and dairy sector, the price pressure has moved toward producers of raw milk. Through new European, national and private standards and global actors tapping into the Romanian market this development is reinforced. At the same time, the smallholders, formerly accepted to be acting on an informal level, cannot access their main distribution channels anymore. Additionally, through several legal constraints being developed since Romania’s accession to the European Union, the smallholders are neither able to issue invoices, nor to access certain subsidy programmes as they are not considered juridical persons. This article focuses on the consequences of this disembedding of farmers. The peasants are pushed toward informal activities or value chain positions, in which they do not have any bargaining power with the globally sourcing intermediaries they are supplying. The contemporary approaches of global value chains and global production networks build the theoretical framework for the study. Here it is argued that informal markets must be included into these approaches more concisely. 相似文献

Incentive programs to encourage landowners to protect habitat should be carefully designed to avoid motivation crowding: basically, replacing intrinsic reasons such as a land ethic with extrinsic ones like payments. Little research on motivation crowding tests real programs, and no such work has been done in Canada. We surveyed farmers in Nova Scotia in 2017 to explore whether participation in a new incentive program called Wood Turtle Strides, or knowledge about a similar incentive program potentially available in the future, would alter reported motivations to use riparian setbacks and buffers. Motivations to use setbacks or buffers were heavily intrinsic across all four survey cohorts: wildlife stewardship and sacrifice motivated actions more than social pressures. We were not able to statistically test for motivational crowding due to low program uptake and thus post-program survey responses, but there was no evidence of second-hand crowding: farmers being motivated by hearing about a program in an adjacent jurisdiction. Findings point to the significance of wildlife stewardship for many farmers, and persistent resistance to conservation among others, as well as a risk of low additionality. More post-program research is necessary to fully understand the program's net impact on motivations and conservation. 相似文献

ABSTRACTFrom the beginning of the 1950s, milking machines increasingly replaced former agricultural workers in West German stables who now preferred better-paid jobs in the industrial sector. The investment necessary for the milking machines led to new ideas about economic thinking and production-optimization, which changed the interplay among human, animal and technology. Within less than two decades, cattle farming in the Federal Republic of Germany changed from an animal-lacking, devastated economic branch of manual labour to a mechanized profit-oriented industry, which produced more than was demanded. This essay challenges the prevailing historical interpretation in which the industrialization of farming has been described as one of the last stages of capitalism’s penetration of society. Central aspects of capitalism remained unfulfilled: there was neither a free market nor individual autonomy of entrepreneurs, and wage labour literally vanished within the barns. A close-up view of the practices at the place of action reveals an arbitrary mixture of efficiency and care that made the industrialization of animal farming differ from the traditional narrative of capitalistic expansion. When animals are the resources to be utilized, capitalist economic activity reaches its limits at the point where the animals’ vital processes begin to malfunction. By bringing together human-animal studies with economic history, this article offers new insights into the role of animals as living beings in history as well as into the expansion of capitalism in an economic sector that continued to operate according to its own rules. 相似文献

历史时期射阳湖演变模式研究 总被引:2,自引:0,他引:2

射阳湖历史上曾是江苏境内著名的大湖。历史时期,湖区经历了浅水海湾—古泻湖—淡水湖泊—沼泽性湖泊—平原沼泽的演变模式。春秋以前,本区是里下河浅水海湾的一部分;春秋至唐代,本区由古泻湖逐步演变为淡水湖;南宋以来,1128年黄河夺淮以后,大量泥沙进入本区,湖区淤积迅速,成为沼泽性湖泊,加之人类开发活动的深刻影响,射阳湖逐渐演变为里下河平原的一部分。 相似文献

抗美援朝运动期间,南京市医药卫生界组建医疗团奔赴前线。为保证顺利完成各项任务,医疗团在组织宣传、任务分配、经费筹措、人员轮换及家属安抚等方面均做了有效安排。服务期间,医疗团在救治伤病员、建立血库、营地防疫及帮助野战医院建章立制、改进设施、培训人才等正规化建设方面贡献突出。通过前线实践锻炼,医疗团团员提高了医疗技术水平和思想政治觉悟,多数成为优秀业务骨干,推动了南京市卫生事业的发展,但仓促组织医疗团也曾给南京市的医疗卫生工作在短期内带来一些问题。 相似文献
