Neotropical cloud forests have been locked away in protected areas that conservationists seek to fashion into spaces exclusively for “Nature,” but they often cannot do so because of the pressure of migrant agriculture, among other factors. The author documents the case of a protected area in Honduras that, while it fails to evolve into an idealized “conservation space,” nevertheless undergoes transformations until it becomes accepted by local actors as a space that provides protection for marginalized groups under threat from a hydroelectric project that seeks to dislodge them. A Deleuzian theoretical approach loosely drawing from complexity theory is utilized to explain the process whereby diverse and conflicting land-use spatialities come to embrace an alien and imposed national park and in the process ally with each other against a perceived greater threat from the outside. The author shows the transformative potentials of protected areas as allies, rather than enemies, of spatial justice movements currently confronting the challenges of “regional economic integration” initiatives such as the Central American Free Trade Agreement. 相似文献

Methodological debates about interviewing ‘elites’ have recently received significant attention within human geography. Many of the contributors to this debate have suggested that there is something intrinsically different about interviewing ‘up’, which geography’s methodological literature needs to make space to consider. This paper argues that, in fact, the distinction between ‘elite’ interviewees and other types of interviewees is based on inadequate and widely critiqued conceptions of power. If, instead, geographers employ a poststructural understanding of power, we may be able to achieve a more sophisticated analysis of power relations within the interview space. 相似文献

The interaction of geomorphic and ecologic landscape components has been largely conceptualized as independent. In one direction, geomorphic processes and landforms shape the distribution of biota. Conversely, in the other direction, biota modify geomorphic processes and landforms. Increasingly, the interactions between geomorphic and ecological components are more circular and developmentally intertwined. In this paper, I integrate these two independent perspectives within the framework of complexity theory. I outline four themes that characterize complex systems in biogeomorphology: multiple causality and the concept of recursivity, the influence of organisms that function as ecosystem engineers, the expression of an ecological topology, and ecological memory. Implicit in all of these themes is the recognition that biogeomorphic systems are open and path dependent. They may exhibit a range of assembly states, from self-reinforcing stability domains to more transient configurations of organisms and environment. 相似文献

This article analyzes changing forms of transnational security governance and security expertise in Guatemala. It is argued that the dynamics of transnational security governance in Guatemala are directly related to the local appropriation of knowledge promoted by external security experts. As an expertise-based form of “intervention by invitation,” local political and economic elites engage in securitization strategies in order to invite external experts to intervene. In turn, through their intervention these experts provide resources that are “captured” and exploited by local actors to pursue their own interests. As a consequence, transnational security governance fails as it deviates from the original plans and programs experts try to implement. The analysis of these processes sheds light on how and why failure in the context of transnational security governance is productive. Failure, we argue, triggers a self-reinforcing interventionary feedback loop that aims at “fixing” the shortcomings of previous interventions by mobilizing new forms of external security expertise. In tracing the dynamics of this interventionary feedback loop over time, this article contributes to understanding of the role of experts and policy failure in the (re)making of transnational security governance. 相似文献

By applying the 'theory of synchronization' from the science of complexity to studying the regional regularity of ore formation within the Nanling region of southern China,a characteristic target-pattern regional ore zonality has been discovered.During the early and late Yanshanian epoch(corresponding respectively to the Jurassic and Cretaceous periods),two centers of ore formation emerged successively in the Nanling region;the former is mainly for rare metals(W,Sn.Mo.Bi,Nb) and one rare-earth element(La... 相似文献
