Despite decades of efforts to curb the global supply of illicit drugs and significant shifts in how those efforts are designed and implemented, illicit crop cultivation persists. In this paper, we examine state and international development efforts to eradicate coca in Peru, opium poppies in Laos, and cannabis in California, USA and the ever-changing discourses used to justify and design these interventions. Scholarship in political geography frames eradication interventions as serving ongoing efforts to extend state and market power into the regions in which illicit crops are grown and to marginalize the people growing them. We find that environmental discourses are increasingly used to assert the need for continued illicit crop interventions, and that these discourses articulate with historical and ongoing portrayals of smallholders as environmentally destructive. Environmental harm narratives that justify enforcement and eradication efforts under the guise of protecting ecosystems from illicit crop farmers can become self-fulfilling prophecies when they disproportionately impact smallholders and push them into marginal geographic and economic positions. Our cases illustrate that environmentally-justified interventions drive cycles of marginalization for illicit crop smallholders, often conditioned by race or ethnicity, who are then portrayed as environmental criminals. Meanwhile, new state-sanctioned spaces of opportunity and profit are created for more powerful actors who are able to capitalize on the removal of illicit crop growers from the land.  相似文献

Trace element compositions of 25 shards of Chinese Late Ming export blue-and-white porcelain from Zhangzhou and Jingdezhen kilns are analysed by Inductively Coupled Plasma Mass Spectrometry. Principle components analysis and REE distribution curves are used to establish method for provenance unknown Chinese export blue-and-white porcelain which may have originated from Zhangzhou or Jingdezhen kilns. By matching the REE distribution curves of Zhangzhou kiln samples and parent rocks of the possible clay sources used to make Zhangzhou blue-and-white, and comparing it with previous results of geological, geochemical and archaeological researches, the clay used for producing Zhangzhou export blue-and-white has been identified as having been collected from the weathered shells of a nearby potassium feldspar miarolitic granite outcrop.  相似文献

Migration theories often ignore the role that states play in stimulating migration through public assistance policies. Using the case of Mexico, this article explores the role of the state as a migrant‐producing actor by examining the relationship between migration and social assistance policies in the form of monetary cash transfers. It argues that direct, unconditional cash transfers, like those provided by agricultural programs such as Procampo, rather than providing the incentives needed to retain individuals in their home country, may instead be providing the resources needed to migrate, particularly if the amount of the transfer is insufficient to spur investment. Instead of discouraging migration by enhancing economic opportunities and reducing poverty, such policies can actually make it easier and more appealing for its beneficiaries to migrate.  相似文献

Two Taiwan-based economists estimate the technology content of exports by the machinebuilding industry of the East Asia region during 2004-2008, using comparative analysis to clarify changes in the relative competitiveness of four East Asian nations (China, Japan, South Korea, and Taiwan) accompanying the formation of a regional trading bloc and production networks. In particular, they examine the technology content of these countries' machinebuilding sub-industries' exports within the Southeast Asian market (documenting the rise of the machinebuilding industry in China) as well as the penetration of Japanese, South Korean, and Taiwanese sub-industries into China's market. The results point to areas of emerging competition among China, South Korea, Japan, and Taiwan for East Asian markets, which can only be expected to intensify in the future.

2012年7月至9月,为探索麦类作物和外来畜养动物的传播途径,青海省文物考古研究所对位于青海互助土族自治县加定镇加塘村的金禅口遗址进行了考古发掘。共揭露齐家文化时期房址5座、灰坑15个、墓葬1座和陶窑2座,出土陶器、石器、骨器、铜器、木器等200多件及大量动、植物遗存。本文对其中的典型遗存进行了详细介绍。通过与邻近地区的同类文化遗存进行比照,本遗址出土的齐家文化典型器型与其存在许多相似之处。选取炭化植物种子10个样品,小麦、大麦、粟和黍,经北京大学考古文博学院碳十四实验室进行测年,数据结果的年代范围在2200~1750BC。综合考虑基本上反映了金禅口遗址齐家文化聚落的绝对年代。遗址中出土的众多细石器和大量动物骨骼反映了发达的畜牧业和狩猎经济。而通过对遗址中采集的土样轻浮物进行鉴定,显示碳化农作物种子10163粒,占出土碳化植物种子总数的90.4%,表明采集业是当时经济生活的重要补充,但农业仍是主要的生计方式。由此可见,金禅口遗址所处的自然环境决定了齐家文化时期先民的生业模式复杂多样。  相似文献

随着经济全球化的深入发展,自由经济区在推动国民经济总体发展战略实施与经济体制改革、促进区域经济和城市化发展等方面发挥了重要作用。20世纪60年代,台湾建立了世界上第一个正式以\"出口加工区\"命名的经济型特区,通过不断转型升级推动了台湾的工业化和社会经济发展。本文通过文献归纳,总结了台湾经历的\"出口加工区-科学工业园区-自由贸易港-自由经济示范区\"四个发展阶段的特点;从目标、政策法规、管理、产业和空间结构入手,归纳出台湾自由经济区的形成演化规律;并认为要素、产业、效益、创新、政策、市场、环境各动力因素相互作用,构成推动其演化的动力机制。本研究对完善自由经济区形成演化理论探索和国内自贸区建设具有一定参考意义。  相似文献

In this paper, I examine the speculative dimensions of biodiesel production in Northeast Brazil under the National Program for the Production and Use of Biodiesel (PNPB), by focusing on the case of castor oil plant (Ricinus communis) in semi-arid Bahia, a promising flex crop that was said to generate social, environmental and economic benefits, especially for the historically marginalised Northeast peasantry. I argue that speculative practices over castor have relied on state policies and discourses as well as biophysical and biotechnological (im)materialities that are transforming agrarian relations in ways that compromise peasants’ control over their (re)productive systems while promoting the expansion of the agroindustrial frontier. By examining the everyday, performative and place-based character of speculative biodiesel practices and their uneven and contested socioenvironmental implications, this paper contributes to current political ecology debates on the nexus between agroenergy development, nature’s capitalist valuation and rural dispossession.  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 article examines the economic and political impact of the Second World War upon a small outpost of Britain’s informal empire. It analyses the multiple ways in which the economy, trade and governance of the Trucial Coast were disrupted, disturbed and challenged by the exceptional circumstances of the war. In response to these circumstances, a variety of emergency arrangements were introduced, resulting in an unprecedented degree of involvement of outsiders and foreign agencies in the management of the local economy. The transformation of Britain’s traditional policy of non-interference in the internal affairs of the Trucial Coast is traced back to the exigencies of wartime conditions.  相似文献
