Threat level green: Conceding ecology for security in eastern Europe and the former Soviet Union

Following the collapse of the Soviet Union, the predicted scenarios of Central Asian water wars and catastrophic nuclear accidents have failed to materialize. However, the Aral Sea continues to shrink apace, and dangerous Soviet-built nuclear reactors have since proliferated in the former eastern bloc. These seemingly paradoxical outcomes can in part be attributed to the framing of these environmental issues as security matters by leading international regulatory, aid and lending institutions. Integrating these environmental concerns with the realist worldview of security studies systematically emphasized security dimensions at the expense of ecological concerns even amongst organizations distant from traditional defense affairs. This article proposes that international security strategy in this period is one of environmental appeasement defined as the systematic granting of ecologically unfriendly concessions in order to reduce short-term security risks. The article presents evidence that this appeasement strategy generated seemingly impressive results in terms of ameliorating short-term security risks, while actually exacerbating the underlying ecological situation. The article argues that while the foundational environmental risks remain unaddressed, the associated security threats have likewise not been ultimately resolved.     

湖南洛塔屋檐洞水库生态安全指标体系及综合评判

本文以DSR模型为框架建立了湖南洛塔屋檐洞水库生态安全评价指标体系,并引入缀块丰富度密度、聚集度、景观均匀性指数等景观生态学指数,采用层次分析和模糊评判有机结合的综合方法,从生态安全状态、压力、响应三个指标体系角度出发,具体分析了屋檐洞库区自然、社会、经济三方面的生态安全问题,对库区生态安全进行综合评价,评判出屋檐洞水库库区系统生态安全属于安全级别,并根据评价中间结果找出生态安全响应是洛塔中寨水电站建设的潜在生态危险因素,提出建立合理科学的生态补偿机制以及库区生态安全预警系统等对策.

试论生态旅游的生态化道路--以自然生态旅游区为例

生态旅游已成为当今世界旅游发展的潮流。然而，在生态旅游开发过程中，存在着众多的。非生态化”现象，尤其是在自然生态旅游区。分析当前自然生态旅游区旅游开发和建设中的“非生态化”现象，主要包括盲目开发，自然景观破坏严重；游客严重超载，生态环境受破坏；人造景观和设施泛滥，景观污染和趋同现象严重；管理和文明建设落后，文化景观功能退化或受损等。运用景观生态学原理和生态安全理论等，从景观功能分区、旅游生态管理容量、景观结构生态设计、景观生态安全格局构建、生态教育等方面提出自然生态旅游区的生态化道路。

New power relations served here: The growth of food banking in Chicago

While some non-profits have suffered under the political and economic pressures of neoliberal urban governance reform, others have emerged as important institutional players in local governance regimes. This article highlights how non-profits food banks in Chicago have commercialized in order to respond to increased demand, enhance their institutional independence from government, and reassert their local dominance in emergency food service delivery. From a food bank member agency perspective, the consolidation of food bank institutional power has produced new bureaucratic limitations, user fees, and increased competition. These shifts reveal the rise of metropolitan food banks as important players in neoliberal urban governance regimes, as they control the conceptualization of hunger, management of poverty, and organization of food distribution systems.     

The Role of Coffee in the Development of Southwest Ethiopia's Forests: Farmers' Strategies,Investor Speculation,and Certification Projects

This article examines the role of coffee in the agriculture of southwest Ethiopian highlands, a context characterized by recent huge private coffee estate developments, coffee certification projects and smallholdings. The analysis shows that smallholder farmers prioritize staple crops, and allocate land and labor to coffee only once food production objectives have been reached. It also underscores the diversity of the local peasantry, often treated as a homogeneous group in development projects designed to boost farmers' income through coffee production. Based on this analysis, the article evaluates the effects of recent coffee-oriented development policies: state forest concessions for coffee investment, and two coffee certification projects (UTZ-Certified and Fair-Trade/Organic). Because they omit the differentiated farmers' strategies, these certification initiatives fail to improve local populations' livelihoods and accelerate incipient socioeconomic inequalities. Moreover, when applied to big private plantations, they participate in farmers' dispossession from critical forest resources essential to households' food self-sufficiency.
