Labour geography aims to explore aspects of workers’ agency that have not yet been at the centre of research, this includes: the links between working-class politics and local communities, the interdependence of global economic networks and working-class activities, and the spatial dimension of workers’ organisations. Although these aspects are relevant for the dynamics of mass strikes, an analysis of mass strikes has been largely absent from debates in labour geography. Rosa Luxemburg’s seminal analysis of strikes in Russia demonstrated the rapid spatial expansion of these movements without any central organisation. Similar phenomena have occurred in recent mass strikes in the emerging economies. This text shows how mass strikes in Brazil, India and South Africa can be investigated through a labour geography lens and calls for a renewed debate on how a ‘strike wave’ is defined or understood.  相似文献

Low-income informal sector contexts are rife in practices that retain value of materials and goods, but in the academic literature and policy debates these practices are seldom considered as part of the circular economy (CE). This is a major omission in CE discourse, as over 60 percent of the world’s employed population is in the informal sector and many of them make their living from circularity practices. Hence, our paper advances a globally covering understanding of CE by focusing on local practices constituting CE in the overlooked contexts of low-income informal markets of emerging economies, and on the motives behind the practices. To that end we introduce the notion of Necessity-Driven Circular Economy, defined as a set of locally embedded and interlinked formal and informal practices aimed at restoring and retaining the value of goods and materials for as long as possible, based on economic necessity and opportunities for income generation. We substantiate this conceptual work with our empirical findings from low-income urban communities in Brazil, India, and Tanzania. This allows us to capture the essential characteristics of necessity-driven circular economy. These characteristics draw attention to the social and cultural embeddedness and the interweaving of consumption and production in necessity-driven circular economy, as opposed to the dominant techno-economic and industry-focused circular economy conceptualizations that are typical in academic discourse and portray developed country contexts. Finally, we discuss conceptual and practical relevance of necessity-driven circular economy and point out its system-level implications for policymakers and businesses.  相似文献

An integrated framework for disaster risk management is presented to cope with the risk of low-probability high-consequence (LPHC) disasters in urban communities. Since the 2000 Tokai flood in Japan, there has been a shift in the management strategy from disaster prevention with a presumed zero risk to disaster reduction with an acceptable risk. The framework consists of: (i) integration of a different categories of risk reduction options in terms of structural and nonstructural measures, regulation and market-oriented measures, (ii) strengthening of the capacity of local communities to make their own management choices for LPHC-type disaster risks, and (iii) promoting the participation of stakeholders throughout the entire cycle of risk management. The interdisciplinary framework is discussed with reference to lessons learned from two recent major flood disasters (the 2000 Tokai flood and the 2004 Niigata flood). To implement the goals of the integrated framework, a participatory platform for disaster risk communication called “Pafrics” has been developed. Preliminary results of the pilot study of participation and risk communication supported by Pafrics are presented.  相似文献

One of the most protracted post-Soviet conflicts of the 1990s was a territorial dispute between Armenia and Azerbaijan over the contested Karabakh region. Years of ethnic violence led to the displacement of nearly a million refugees, as well as a public health crisis that included epidemics of malaria, diphtheria and other preventable diseases. Malaria is not usually considered a health risk in temperate climates, but seasonal epidemics were widespread throughout the Caucasus in the early decades of the twentieth century. This paper combines qualitative historical research with geospatial analysis to explore how endemic malaria was controlled during the Soviet era, and how ethnic conflict reconfigured local ecologies to facilitate the re-emergence of P. vivax after the Soviet collapse in the 1990s. This research reveals that ethnic conflicts have specific qualities that increase risks of infectious and vector borne disease outbreaks, even in places that have successfully achieved a modern health and mortality profile. The risk amplifiers of ethnic conflicts include 1) the creation of contested spaces controlled by separatists that are outside of any national public health surveillance system; 2) mass population movements and refugee outflows due to ethnic violence; and 3) changes in land use that expand potential mosquito breeding sites throughout the conflict zone. Continued hostilities between Armenia and Azerbaijan, combined with the repopulation of key vector species (specifically An. sacharovi) lead us to conclude that populations in the Caucasus remain vulnerable to resurgent outbreaks of ethno-nationalist violence as well as the return of seasonal malaria, even after decades of successful control.  相似文献
