Endorheic currents in ecology: an example of the effects from scientific specialization and interdisciplinary isolation

ABSTRACT

Mainstream ecological thought is explored in three sections: (i) Epistemological traits. Given the typical scientific development and the necessity of preserving our intellectual heritage, the conservatism outlined in (i) is cyclical, so its stages are graphically summarized. (ii) Methodological benchmarks antithetically derived from (i), in order to get faster advancement consistent with the growing environmental challenges which spur ecological development. (iii) The renaissance of an old paradigm. This section exposes the misunderstanding of the physical concept of equilibrium by the mainstream ecological thought; this explains its current state. Consequently, section (iii) also summarizes the evolution of a recent set of proposals (organic biophysics of ecosystems) that rescues the foundational paradigm of ecosystem ecology based on physics, neglected by the mainstream thought before producing its most valuable results. We highlight that the main problems emerge from the weakness of integration between ecology, physics and epistemology, and spurious links between ecology and neoclassical economics.     

The integration of geography in a curriculum focused to internationalization: an interdisciplinary liberal arts perspective from the Netherlands

Internationalization has been an important concept in higher education over the past two decades. The way that internationalization is manifest has consequences to academic disciplines, including geography. A new system of liberal arts colleges in the Netherlands has created opportunities for interdisciplinary education, representing a departure from the traditional model of European higher education. At Leiden University College the focus on global challenges created an opportunity for geography to be integrated into a diverse interdisciplinary and international curriculum. The positioning of geography into the curriculum, however, occurred because its adaptability and breadth, which enabled it to be incorporated into diverse facets of the overall teaching programme. To be successful, however, geographers should be cognizant of specific facets of the discipline suited for an international context. The case study herein reviewed highlights important differences between the U.S. and Dutch (European) context. Additionally, important points for academic geographers (academics) who are in interdisciplinary programmes (i.e. not a geography department) are emphasized, which relates to the development of course materials to suit an international context. The identification of key thematic and methodological disciplinary strands serves as bridges to interdisciplinary opportunities, which was essential to geography’s successful establishment within an international curriculum.     

A gender analysis of everyday mobility in urban and rural territories: from challenges to sustainability

Gender differences in mobility patterns between women and men have long been acknowledged. This study analyses how these differences are reproduced in different urban and rural contexts. Using mobility data from a large travel survey taken in 2006 in Spain, we examine the differences between gender mobility through age, modal split and trip purposes. Special attention is paid to how territory shapes mobility and how these territorial settings differently affect gendered mobilities. The use of this data source allows the comparison of all trips made by the total population, including all means of transport. By taking a global view on mobility, the uneven relationships that men and women have with different means of transport become more visible. After disaggregating data by age and territorial settings, results show that women are using sustainable transport modes more often than men, and travelling for more diverse reasons. Gender is thus a fundamental variable in understanding modal split and, by extension, transport sustainability, in terms of energy consumption and the emission of greenhouse gases. From this point of view, we consider women's mobility knowledge and practices – typically related to the most sustainable means of transport – as factors with rising value that could effectively guide public policy in its way to promote more sustainable mobility patterns.     

Impacts of urban living labs on sustainability transitions: mechanisms and strategies for systemic change through experimentation

ABSTRACT

Urban Living Labs (ULL) are considered spaces to facilitate experimentation about sustainability solutions. ULL represent sites that allow different urban actors to design, test and learn from socio-technical innovations. However, despite their recent proliferation in the European policy sphere, the underlying processes through which ULL might be able to generate and diffuse new socio-technical configurations beyond their immediate boundaries have been largely disregarded and it remains to be examined how they contribute to urban sustainability transitions. With this study, we contribute to a better understanding of the diffusion mechanisms and strategies through which ULL (seek to) create a wider impact using the conceptual lens of transition studies. The mechanisms of diffusion are investigated in four distinct ULL in Rotterdam, the Netherlands and Malmö, Sweden. The empirical results indicate six specific strategies that aim to support the diffusion of innovations and know-how developed within ULL to a broader context: transformative place-making, activating network partners, replication of lab structure, education and training, stimulating entrepreneurial growth and narratives of impact.     

Inclusive growth from an urban perspective: a challenge for the metropolis of the twenty-first century

This paper addresses the study of inclusive growth from an urban perspective. It proposes to focus the relationship between urban economic growth and income distribution in cities in which manufacturing production and external demand play a central role. Opposed to the literature that considers economic growth leads to an increase in inequality in income distribution, we present some operative economic tools from Marshallian Industrial Districts theory and from urban economic theory with which to develop an economic strategy for inclusive urban growth, making possible to achieve simultaneously economic growth and improvements in income distribution. An interesting example of a metropolis with a dynamic of economic and employment growth compatible with a reduction in income inequality is provided by Barcelona. This metropolis disposes a Survey of living conditions and habits of the population since 1986 that allows an analysis in terms of inclusive urban growth.     

Daily urban systems explained from the household perspective: an exploratory research on how the spatial interactions of the individual households shape the structure of daily urban systems

The concept of the Daily Urban System (DUS) has gained relevance over the past decades as the entity to examine and explain the functionality of the urban landscape. Daily Urban Systems are usually defined and measured by the strength of commuter or shopper flows between the nodes of the system. It is important to realize that these Daily Urban Systems are the accumulated pattern of individuals making frequent, recurring trips to other localities than their own. Understanding the microeconomic decisions behind these spatial interactions will help in assessing the functional and spatial structure of DUS. In this paper is explored how, based on Dutch empirical data, the individual household’s spatial interactions shape the daily urban system and how the destination of these interactions correlates with personal and spatial variables and motives for interaction. The results show that the occurrence of non-local spatial interactions can be explained by the size-based Christallerian hierarchy of the localities of residence, but that it is the regional population – or market potential – that explains and moderates the sorting of households and the intensity and direction of their spatial interactions in the DUS, matching agglomeration theory.
