In recent years, the Smart City has become a very popular concept amongst policy makers and urban planners. In a nutshell, the Smart City refers to projects and planning strategies that aim to join up new forms of inclusive and low-carbon economic growth based on the knowledge economy through the deployment of information and communication technologies. However, at the same time as new urban Smart interventions are being designed and applied, insufficient attention has been paid to how these strategies are inserted into the wider political economy and, in particular, the political ecology of urban transformation. Therefore, in this paper we critically explore the implementation of the Smart City, tracing how the ‘environment’ and environmental concerns have become an organising principle in Barcelona’s Smart City strategy. Through an urban political ecology prism we aim to critically reflect upon the contradictions of the actually existing Smart City in Barcelona and how Smart discourses and practices might be intentionally or unintentionally mobilised in ways that serve to depoliticise urban redevelopment and environmental management. The paper stresses the need to repoliticise the debates on the Smart City and put citizens back at the centre of the urban debate.

This article analyzes degrowth, a project of radical socioecological transformation calling for decolonizing the social imaginary from capitalism's pursuit of endless growth. Degrowth is an advanced reincarnation of the radical environmentalism of the 1970s and speaks to pertinent debates within geography. This article benefits from Ursula Le Guin's fantasy world to advance the theory of degrowth and respond to criticisms that degrowth offers an unappealing imaginary, which is retrogressive, Malthusian, and politically simplistic. We argue instead that degrowth is on purpose subversive; it brings the past into the future and into the production of the present; it makes a novel case for limits without denying that scarcity is socially produced; and it embraces conflict as its constitutive element. We discuss the politics of scale of the incipient degrowth movement, which we find theoretically wanting, yet creative in practice.

Context: Most protected areas are managed based on objectives related to scientific ecological knowledge of species and ecosystems. However, a core principle of sustainability science is that understanding and including local ecological knowledge, perceptions of ecosystem service provision and landscape vulnerability will improve sustainability and resilience of social-ecological systems. Here, we take up these assumptions in the context of protected areas to provide insight on the effectiveness of nature protection goals, particularly in highly human-influenced landscapes. Objectives: We examined how residents’ ecological knowledge systems, comprised of both local and scientific, mediated the relationship between their characteristics and a set of variables that represented perceptions of ecosystem services, landscape change, human-nature relationships, and impacts. Methods: We administered a face-to-face survey to local residents in the Sierra de Guadarrama protected areas, Spain. We used bi- and multi-variate analysis, including partial least squares path modeling to test our hypotheses. Results: Ecological knowledge systems were highly correlated and were instrumental in predicting perceptions of water-related ecosystem services, landscape change, increasing outdoors activities, and human-nature relationships. Engagement with nature, socio-demographics, trip characteristics, and a rural–urban gradient explained a high degree of variation in ecological knowledge. Bundles of perceived ecosystem services and impacts, in relation to ecological knowledge, emerged as social representation on how residents relate to, understand, and perceive landscapes. Conclusions: Our findings provide insight into the interactions between ecological knowledge systems and their role in shaping perceptions of local communities about protected areas. These results are expected to inform protected area management and landscape sustainability.

In this paper we explore the new orientation taken by Spanish water policy since the beginning of the 21st century and very specifically the shift towards desalination as an alternative to other water supply options such as river regulation or inter-basin water transfers. Desalination has been seen as the cure for everything that dams and inter-basin water transfers were unable to solve, including droughts, scarcities, social conflicts, environmental impacts, and political rivalries among the different Spanish regions. Desalination also means a new and powerful element in water planning and management that could provide water for the continuous expansion of the urban and tourist growth machine in Mediterranean Spain and thus relax possible water constraints on this growth. However, by 2012 most new desalination plants along the Mediterranean coast remained almost idle. Focusing on the case of the Mancomunidad de Canales del Taibillla in South-eastern Spain, our aim is to develop a critical, integrated and reflexive perspective on the use of desalination as a source of water for urban and regional growth.Part of this research was funded by the Spanish CICYT under grant numbers CSO2012-36997-C02-01, CSO2012-36997-C02-02 and JCI-2011-10709
