From catfish to organic fish: making distinctions about nature as cultural economic practice     

Becky Mansfield 《Geoforum》2003,34(3):329-342

This paper addresses the cultural economy of nature and the material culture of economic practice. Attending to ways that cultural notions about the biophysical world play key roles in political economic conflicts, discussion centers on two recent debates involving the cultural economy of seafood production and trade. The first debate is over whether the label “catfish” should include catfish imported from Vietnam into the United States; the second deals with whether fish and shellfish should be eligible to be certified “organic” under new US regulations. Analysis reveals that the key dynamic in these debates is not necessarily how people think about “nature”, but instead is how people make distinctions about the world. Rather than focusing on what is natural or not, key actors make distinctions among both organisms and environments. The ways that different groups define and enclose the biophysical world works to distinguish places as either appropriate or not for certain kinds of production activities. The overall argument is that significance and meaning of the biophysical become implicated in economic geographies by making distinctions about the world that then become important for how economic activity can work. As such, cultural economic approaches should attend to the ways that the biophysical is involved in relations such as competition and international trade, while nature-society approaches should shift focus from Nature to specific aspects of the biophysical world.  相似文献   

绿洲环境形成机制和干旱区生态环境建设对策   总被引：18，自引：9，他引：18  

胡隐樵  左洪超 《高原气象》2003,22(6):537-544

绿洲生态环境建设对我国西北干旱地区的经济可持续发展有着特殊的战略意义。本文总结了绿洲小气候的一系列研究结果。根据绿洲小气候的形成机制和绿洲稳定性状态，提出了我国西北干旱区生态环境建设对策及提高绿洲的稳定性和抗干扰能力的建议。指出绿洲生态环境保护和建设对策应充分利用绿洲冷岛效应小气候特点，把有限的水资源与丰富的光热资源结合起来，发展独特的气候生态类型。对于不同稳定状态绿洲生态环境建设应采取不同对策。并指出良性绿洲生态环境建设应发展耐旱喜阳生态农业，提高水资源利用效率；低效绿洲生态环境建设应尽量调整绿洲格局，将破碎绿洲连通成片，力图减小晒衣绳效应；“退化绿洲”生态环境建设的对策是在足够水资源供给的条件下修复生态系统，限制地下水开采和农牧业的发展，抑制生态系统的进一步恶化。  相似文献

基于生态经济理论的生态需水计算方法研究   总被引：9，自引：0，他引：9       下载免费PDF全文

乔云峰  王晓红  纪昌明  王丽萍 《水科学进展》2004,15(5):621-625

在简述生态需水研究现状的基础上,结合以可持续发展为基础的生态经济理论,提出了基于生态经济思想的生态需水概念,并进行了理论分析.根据生态经济领域中的生态价值理论,确定不同生态需水量条件下的生态价值,进而通过水资源的生态价值与经济价值之间的相互关系确定合适的生态需水量,并通过实例对该方法的具体步骤进行了说明,认为由该法所确定的生态需水量符合客观实际,可以作为生态建设过程中生态需水研究的方法之一.该法通过水资源将生态系统和经济系统联系在一起,对于研究可持续发展条件下的水资源利用有一定的现实意义.  相似文献

Urban land transformation for pro-poor economies   总被引：1，自引：0，他引：1  

Solomon Benjamin 《Geoforum》2004,35(2):177-187

The transformation of land into a setting for clustering local economies can become an important cornerstone of poverty policy. This transformation has several functional aspects, which in turn have important institutional and political aspects. Underlying both the functional and institutional factors is the role of local government and local democracy. Such a conceptualization puts to center stage several paradoxes: A terrain that seems “slum-like” turns out to be highly productive and employment generating. Complex tenure forms and mixed land use seen as “unplanned” turn out to be pre-requisites for economic development. There are institutional paradoxes that contrast efforts at “transparency” and managerial “best practices”. Here, the messiness of local bureaucracies in municipal government turns out to be critical for poor groups to influence interventions in their favor. Influencing the public process may be more effective in stealth-like ways rather taking a more visible approach. Most fundamentally these issues remind us that the potential of cities to reinforce or reduce poverty moved far beyond projects and programs and the normative frameworks used by planners and administrators. Instead, it is the transformative process of turning land into economic settings that might be at the center stage. This is a stage where poor groups are the central actors who stealth-like draw on complex alliances across ethnic and class lines to shapes cities in their interests.  相似文献
