Estimating the extent and structure of trade in horticultural orchids via social media

The wildlife trade is a lucrative industry involving thousands of animal and plant species. The increasing use of the internet for both legal and illegal wildlife trade is well documented, but there is evidence that trade may be emerging on new online technologies such as social media. Using the orchid trade as a case study, we conducted the first systematic survey of wildlife trade on an international social‐media website. We focused on themed forums (groups), where people with similar interests can interact by uploading images or text (posts) that are visible to other group members. We used social‐network analysis to examine the ties between 150 of these orchid‐themed groups to determine the structure of the network. We found 4 communities of closely linked groups based around shared language. Most trade occurred in a community that consisted of English‐speaking and Southeast Asian groups. In addition to the network analysis, we randomly sampled 30 groups from the whole network to assess the prevalence of trade in cultivated and wild plants. Of 55,805 posts recorded over 12 weeks, 8.9% contained plants for sale, and 22–46% of these posts pertained to wild‐collected orchids. Although total numbers of posts about trade were relatively small, the large proportion of posts advertising wild orchids for sale supports calls for better monitoring of social media for trade in wild‐collected plants.     

Analysis of the Energy Embodied in Foreign Goods Trade of China

In recent years, scientists have been increasingly interested in the energy embodied in traded goods among countries. In this article, the direct energy intensities in various economic sectors of China were calculated with the data of energy consumption and output value of each sector, and the input-output table was used to estimate the external energy consumption. The total energy intensity of all sectors was then obtained. From the data of international trade, the energy embodied in goods trade of China was estimated for the period of 1994-2001. During this period, the average energy intensity of imported goods was always higher than that of exported ones. As a country with a surplus in international goods trade, China actually imported net embodied energy in the past few years. The net embodied energy imported was at the same magnitude of the imported energy in the form of fossil fuels.     

China-Indian Silk Trade： Current Production and Future Prospects

As an important traditional labor-intensive industry of both India and China, the cocoon silk industry has long made great contributions to the ecological environment protection, rural economic development and the increase in export income of both countries. India is not only a very important cocoon silk trading partner, but an important production competitor of China. In recent years, there has been a large increase in the production and trade of the cocoon silk between China and India; however, China relies heavily on Indian market, which leads to a tendency of further deterioration in the silk trade environment between both countries. The present article makes an empirical study of the cocoon silk resources of the two countries and the scale, product mix and market structure of China-Indian silk trade from 2001 to 2007. Overall silk trading volumes from China to India and market concentration rate are on the increase because of the superiority of Chinese cocoon silk production over that of India. Owing to scattered market share and export that mainly focused on raw materials product, there has been a phenomenon of price reduction and quantity increase. India carries out fierce competition with China in the international market and even imposes antidumping sanction on Chinese silk, which are key factors restricting further increase between China-India trade. Based on the abovementioned facts, the authors aim to put forward suggestions for steadily developing the production and trade of China＇s silk.     

Structuring Decisions for Managing Threatened and Endangered Species in a Changing Climate

The management of endangered species under climate change is a challenging and often controversial task that incorporates input from a variety of different environmental, economic, social, and political interests. Yet many listing and recovery decisions for endangered species unfold on an ad hoc basis without reference to decision‐aiding approaches that can improve the quality of management choices. Unlike many treatments of this issue, which consider endangered species management a science‐based problem, we suggest that a clear decision‐making process is equally necessary. In the face of new threats due to climate change, managers’ choices about endangered species require closely linked analyses and deliberations that identify key objectives and develop measurable attributes, generate and compare management alternatives, estimate expected consequences and key sources of uncertainty, and clarify trade‐offs across different dimensions of value. Several recent cases of endangered species conservation decisions illustrate our proposed decision‐focused approach, including Gulf of Maine Atlantic salmon (Salmo salar) recovery framework development, Cultus Lake sockeye salmon (Oncorhynchus nerka) management, and Upper Columbia River white sturgeon (Acipenser transmontanus) recovery planning.

社会产品价格对水价的敏感性——基于虚拟水贸易框架的分析

虚拟水贸易是缺水地区从社会经济系统层面解决水资源短缺问题的一种策略选择,但由于长期的低水价,致使很多国家和地区的现实经济模式与虚拟水贸易战略的预期相悖.文章基于水资源投入产出分析方法,构建虚拟水贸易理论框架下的水价敏感性模型,分析水价上涨对各产业产品价格带来的影响.模型结果显示,区域水价提升对各产业产品价格的影响不仅在于该产业直接用水成本的上升,同时也不得不承受其他产业成本上升带来的间接影响,并且这两种影响作用是累加的.宁夏数据的实证得出,水价上涨对农业产品价格的影响最为强烈,批发和零售贸易餐饮业次之,对服务业产品价格的影响最弱.因此,可通过制定合理的水价调整策略,激励水资源极度缺乏的地区实施虚拟水贸易战略,避免过分强调传统的重农发展模式,促进产业结构向先进制造业和服务业转变,实现有限水资源更为合理的利用模式,达到经济发展与水生态的和谐局面.     

中国低碳发展的国际比较:世界贸易格局

近年来随着我国经济的持续平稳快速发展,与之相伴随的碳排放总量持续攀升,中国也因此被推上世界碳减排的风口浪尖.为了明确中国碳排放的国际地位,本文从世界贸易格局视角对中国的碳排放现状进行了国际比较研究.首先分析研究了我国2007年面临的碳排放国际形势,继而对我国的出口贸易形势进行了国际比较,最后采用GDP比例法和类推法对我国商品出口隐含的碳排放进行了初步测算,并分析了剔除出口贸易影响后的我国碳排放情况.通过研究认为:①出口贸易对我国的碳排放总量影响巨大,我国的商品出口占GDP比例长期维持在20%以上,近几年高峰值超过36%;②在当前的世界贸易格局、国际分工体系下,采用“生产者责任体系”碳排放测算模式大大高估了中国的碳排放水平,中国的碳排放总量中有34-60%是为他国服务而产生;③中国在当前世界贸易格局和国际分工体系中的地位使得中国在目前的碳排放测算模式下必然“产生较高的碳排放”;④世界各国应该重新审视和正确认识中国的“高”碳排放形势,中国为世界各国提供商品服务而产生的碳排放不应该受到指责.

A Pluralist–Expressivist Critique of the Pet Trade

Elizabeth Anderson’s “pluralist–expressivist” value theory, an alternative to the understanding of value and rationality underlying the “rational actor” model of human behavior, provides rich resources for addressing questions of environmental and animal ethics. It is particularly well-suited to help us think about the ethics of commodification, as I demonstrate in this critique of the pet trade. I argue that Anderson’s approach identifies the proper grounds for criticizing the commodification of animals, and directs our attention to the importance of maintaining social practices and institutions that respect the social meanings of animals. Her theory alone, however, does not adequately address the role of the state in this project. Drawing on social contract theory to fill this gap, I conclude that the state’s role in regulating the pet trade should be limited to ensuring the welfare of animals in the stream of commerce, not prohibiting their mass marketing altogether.
