This article theorizes the potential roles of the state in the urban commons through an analysis of a slum upgrading program in Thailand that employs collective forms of land tenure. In examining the transformation of the program from a grassroots movement to a “best practice” policy, the article demonstrates how the state has expanded from mere enabler of the commons to active promoter. In the process, the role of many residents has evolved from actively creating the institutions of collective governance— commoning—to adopting institutions prescribed by the state— being commoned. However, by comparing the work to two different groups of communities who work within the context of the policy, the article illustrates how active commoning can still take place in such contexts.

The inland water bodies of northern Chilean Patagonia (38-41°S) have many lakes, wetlands and ponds with different littoral and zooplanktonic crustacean assemblages. This study presents field observations of species associations sampled from shallow wetlands located in the urban zones of Valdivia (39°S) and Puerto Montt (41°S). A species presence-absence matrix was created for calculating the Jaccard Index of community similarity and for testing null models of species associations, with the aim of determining whether species associations are random or not. The results of the Jaccard Index calculations indicated the existence of non-defined groups. The results of the null model analysis denoted the presence of regulating factors for Valdivia wetlands, whereas for Puerto Montt wetlands no such factors could be demonstrated. The outcomes of both the Jaccard Index and the significant null model analysis agree with previous ecological descriptions of changes in trophic status as a consequence of changes in the surrounding basin as a determinant of species associations. The ecology of these communities is also discussed.

AbstractThis article engages the question of what happens to labor as Indian cities become transformed into “global cities.” It does so by focusing on the convergence of three interrelated trends over the past few decades: the informalization of labor, the making of global cities, and the financialization of the economy. The article explains the effect on labor, capital, and urban space of this concatenation of trends. It challenges the conclusion of urbanization scholars who emphasize how labor has been largely excluded and bypassed by the growing urban economy. Instead, the article demonstrates, by using nationwide data as well as examples from Bangalore, that as labor is being displaced from formal employment and as wages become compressed, the urban commons is becoming a more valued terrain. On the one hand, displaced urban and rural workers must increasingly rely on subsistence practices and depend more upon the city's public spaces and goods to survive. On the other hand, these spaces, vital to city life, are becoming attractive to indebted municipal governments and aggressive financial investors for their speculative land values, and hence have led to greater insecurity and dispossession. The global city, therefore, is being built in large part with workers' wageless labor. Consequently, the struggle between capital and labor has reached far “beyond the factory” and farm, to the urban commons, sites simultaneously key to the majority's survival and integral to the urban speculative project of financialization.

Considering place-based participation a crucial factor for the development of sustainable and resilient cities in the post-digital turn age, this paper addresses the socio-spatial implications of the recent transformation of relationality networks. To understand the drivers of spatial claims emerged in conditions of digitally augmented spectacle and simulation, it focuses on changes occurring in key nodes of central urban public and semi-public spaces of rapidly developing cities. Firstly, it proposes a theoretical framework for the analysis of problems related to socio-spatial fragmentation, polarisation and segregation of urban commons subject to external control. Secondly, it discusses opportunities and criticalities emerging from a representational paradox depending on the ambivalence in the play of desire found in digitally augmented semi-public spaces. The discussion is structured to shed light on specific socio-spatial relational practices that counteract the dissipation of the “common worlds” caused by sustained processes of urban gentrification and homogenisation. The theoretical framework is developed from a comparative critical urbanism approach inspired by the right to the city and the right to difference, and elaborates on the discourse on sustainable development that informs the United Nations’ New Urban Agenda. The analysis focuses on how digitally augmented geographies reintroduce practices of participation and commoning that reassemble fragmented relational infrastructures and recombine translocal social, cultural and material elements. Empirical studies on the production of advanced simulative and transductive spatialities in places of enhanced consumption found in Auckland, New Zealand, ground the discussion. These provide evidence of the extent to which the agency of the augmented territorialisation forces reconstitutes inclusive and participatory systems of relationality. The concluding notes, speculating on the emancipatory potential found in these social laboratories, are a call for a radical redefinition of the approach to the problem of the urban commons. Such a change would improve the capacity of urbanism disciplines to adequately engage with the digital turn and efficaciously contribute to a maximally different spatial production that enhances and strengthens democracy and pluralism in the public sphere.
