Divergence,Sensitivity, and Nonequilibrium in Ecosystems

Contemporary theoretical debate in ecology and biogeography is often focused on equilibrium vs. nonequilibrium behavior in ecosystems and on the nature and source of ecosystem dynamics. It is suggested that these debates be recast in terms of the way ecosystems develop and respond to disturbances, rather than in terms of concepts often imported from mathematics, physics, and other fields. Using nonlinear dynamical systems theory, it is shown that key theoretical implications can be cast in terms of geoecologically significant phenomenologies such as divergent evolution, sensitivity to initial conditions and small disturbances, historical contingency, and path dependence. Examples show these phenomena are widely observed in ecosystems. Ecological and biogeographical theory can be problematized from within geography and ecology rather than fuzzy, abstract concepts such as equilibrium, self‐organization, “balance of nature,” or chaos. Complexity, sensitivity, variability, nonsteady states, and other concepts often associated with nonequilibrium or complexity‐theory frameworks have manifestations that are evident in observable ecological phenomena, in addition to theory and models.     

检方施治:防疫方书与清代的疫情防控

抄录、编撰、刊印、传播、参阅防疫方书,是清代疫情期间常见的医疗实践活动。防疫方书的大量涌现是一次次疫病流行激发的结果,是疫情防控实践本身的重要组成部分。它们在染疫病人救治、防疫力量动员、防疫知识整合和普及等方面发挥着独特的媒介作用,是相关人、事、物实现链接和互动的一种重要途径,是人们积极主动地应对疫病、控制疫情、维护生命健康的一种"原动力"。相较于其他常见防疫举措,防疫方书深度参与到多种疫情防控实践中,实际构成了一种自发性、分散性、非制度性的疫病应对机制,具有成本低廉、传导性强、覆盖面广、溢出效应大等特征。     

Governing the Sick City: Urban Governance in the Age of Emerging Infectious Disease

Abstract: Based on a case study of the 2003 severe acute respiratory syndrome (SARS) outbreak in Toronto, Canada, this article suggests that we may have to rethink our common perception of what urban governance entails. Rather than operating solely in the conceptual proximity of social cohesion and economic competitiveness, urban governance may soon prove to be more centrally concerned with questions of widespread disease, life and death and the construction of new internal boundaries and regulations just at the time that globalization seems to suggest the breakdown of some traditional scalar incisions such as national boundaries in a post‐Westphalian environment. We argue that urban governance must face the new (or reemerging) challenge of dealing with infectious disease in the context of the “new normal” and that global health governance may be better off by taking the possibilities that rest in metropolitan governance more seriously.

Capitalist Expansion and the Decline of Common Property Ecosystems in China,Vietnam and India

This article identifies some of the multiple processes of capitalist development through which access to common property resources and their utility for communities are undermined. Three sites in upland Asia demonstrate how patterns of exclusion are mediated by the unique and selective trajectories through which capital expands, resulting in a decline of common property ecosystems. The process is mediated by economic stress, ecological degradation and political processes such as state‐sanctioned enclosure. The first case study from Shaoguan, South China, indicates how rapid capitalist industrialization has depleted the aquatic resource base, undermining the livelihoods of fishing households yet to be absorbed into the urban working class. At the second site, in Phu Yen, Vietnam, capitalist development is limited. However, indirect articulations between capitalism on the lowlands and the peasant economy of the uplands is driving the commercialization of agriculture and fishing and undermining the utility of communal river and lake ecosystems. In the third site, Buxa in West Bengal, India, there is only selective capitalist development, but patterns of resource extraction established during the colonial period and contemporary neoliberal ‘conservation’ agendas have directly excluded communities from forest resources. Restrictions on access oblige them to contribute subsidized labour to local enterprises. The article thus shows how communities which are differentially integrated into the global economy are excluded from natural resources through complex means.

A Speculative Model of Population Influences on Australian Ecology,Economy and Society

A lack of empirical data and sufficient conceptual frameworks precluded the 1994 national population inquiry from proposing demographic targets for the future ‘carrying capacity’ of Australia. A speculative model is proposed here of population impacts in the ecological, economic, social and relational domains. The model is ‘run’ under scenarios of growing and stable population so that key interactions can be explored and thereby advance debate about broader population policy in Australia.     

Material Politics Facing Post-Truth: Speculation,Infrastructure, and Ecology in Turkey

Despite their imposing material presence, the values and harms stemming from the construction of infrastructural megaprojects remain speculative affairs in Istanbul, Turkey. This article distinguishes two modes of speculation pertaining to megaprojects that present different ethical and political possibilities, namely de-materialising and re-materialising speculation. Contributing to debates about material politics informed by Noortje Marres (Material Participation; Palgrave Macmillan, 2015) and William Connolly (The Fragility of Things; Duke University Press, 2013), our framework of de- and re-materialising speculation avoids isolating material and planetary agency to instead consider how their uncertainties and potentials play a role at the intersection with politico-economic life. Accordingly, we analyse the coalescence of ecological and democratic crises. In Turkey, populism’s anthropocentric construction of “the will of the people” exacerbates ecological collapse. But also, ecological collapse inspires a search for a politics and ethics that acknowledge human–nonhuman ecological entanglements. The contestation between de-and re-materialising speculation underscores possibilities and limitations of ecological politics in contexts of populism and post-truth.     

Urban Political Ecology, Justice and the Politics of Scale

This and the subsequent papers in this special issue set out the contours of Marxian urban political ecology and call for greater research attention to a neglected field of critical research that, given its political importance, requires urgent attention. Notwithstanding the important contributions of other critical perspectives on urban ecology, Marxist urban political ecology provides an integrated and relational approach that helps untangle the interconnected economic, political, social and ecological processes that together go to form highly uneven and deeply unjust urban landscapes. Because the power-laden socioecological relations that shape the formation of urban environments constantly shift between groups of actors and scales, historical-geographical insights into these ever-changing urban configurations are necessary for the sake of considering the future of radical political-ecological urban strategies. The social production of urban environments is gaining recognition within radical and historical-materialist geography. The political programme, then, of urban political ecology is to enhance the democratic content of socioenvironmental construction by identifying the strategies through which a more equitable distribution of social power and a more inclusive mode of environmental production can be achieved.     

The Political Ecology of Extraction and Extractive Reserves in East Kalimantan,Indonesia

Extractive reserves established in the Amazon have given development professionals hope for solving two critical problems in conservation and development: the empowerment of indigenous people and the conservation of tropical forests. The extraction of non-timber forest products has provided an important part of the livelihood strategies of rainforest dwelling people and of the regional economy of East Kalimantan for some two millennia. The specific political-economic and environmental circumstances of Indonesia and interior Kalimantan, however, preclude applying the Amazonian model for extractive reserves. Using a political ecology framework, this article analyses sociological and environmental factors emerging over the past two and a half decades and influencing contemporary rattan production and trade. Based on this analysis, the author concludes that the politics of forest management, at both the national and local levels, are more conducive to village level extractive reserves than to regional, labour-based organizations.     

Reconceptualizing Senses of Place: Social Relations, Ideology and Ecology

The purpose of this paper is to reconceptualize sense of place through the examination, re-analysis and theorization of two case studies, one of an ex-urban community in England, the other a Himalayan farming and herding community. The paper begins by examining the traditional locus of sense of place research in humanistic geography with extensions to political geography and interpretive anthropology. Identifying three core components—social, ideological and ecological—of senses of place, the paper goes on to reconceptualize these elements using Habermas's theory of communicative action and Ingold's work on environmental psychology. It then applies this reconceptualization to the case studies of Towcester and Shimshal. The paper concludes by emphasizing the ways these cases enrich our understanding of sense of place, by stressing the theoretical contributions of conceiving sense of place as rooted in theories of social organization and society, and as being variably and contingently ecologically emplaced.
