Resilience and Urban Regeneration Policies. Lessons from Community-Led Initiatives. The Case Study of CanFugarolas in Mataro (Barcelona)

This paper addresses socio-ecological, community-led resilience as the ability of the urban system to progress and adapt. This is based on the socio-cultural, self-organized case study of CanFugarolas in Mataró (Barcelona), for the recovery of a derelict industrial building and given the lack of attention to resilience emerging from grassroots. Facing rigidities (stagnation) observed under the provisions of urban regeneration policies (regulatory realm), evidenced in the proliferation of urban voids (infrastructural arena), the social subsystem stands as the enabler of urban progression. Under the heuristics of the Adaptive Cycle and Panarchy, the study embraces Fath’s model to analyze the transition along, and the interactions between, the adaptive cycles at each urban subsystem. The mixed method approach reveals the ability of the community to navigate all stages and overcome successive ailments, despite seemingly insurmountable obstacles (traps) at the physical support (built stock) and the regulatory arena (urban planning). Further, cross-scale, social-centered interactions (panarchy) are also traced, becoming the “sink” and the “trigger” of the urban dynamics. The community, in the form of an actor-network, becomes the catalyst (through Remember/Revolt) of urban resilience at the city scale. At a managerial level, this evidences its temporal and spatial complementarity to top-down urban regeneration policies.

Resilience through Adaptation: Innovations in Maasai Livelihood Strategies

This article examines strategies adopted by Maasai and other pastoralists in Kenya to adapt to climate change, population growth, land loss, decreasing livestock holdings and land degradation, aimed at achieving greater socio-economic resilience. Using case studies mostly from Narok County and reviewing the increasingly rich literature on pastoralism and conservation in East Africa, we show that pastoralists employ three main strategies to adapt their livelihood systems: intensification (changes in land use systems to increase productivity per hectare); extensification (through territorial expansion into unoccupied areas or territories of neighbouring communities in our cases); and diversification (the combination of pastoralism with other livelihood strategies, mainly farming, conservation, tourism, business and wage jobs, often through migration to small towns or urban centres). Maasai communities have been quick to adopt these strategies, individually or in combination, in order to overcome ecological and socio-economic stress and to pursue opportunities as they arise. Since these strategies are generally compatible with extensive pastoralism, this land use will continue to play a key role in sustaining the livelihoods of people living in semi-arid and arid rangelands. However, when intensification and diversification through the adoption of ranching and farming occur, the rangeland becomes fragmented, with severe impacts on wildlife. In such cases, incentives for sustaining conservation and wildlife tourism will need to increase to compensate land holders for foregoing these more intensive land uses, thus moving towards reconciliation of ecological sustainability and strengthened livelihoods. These findings are illuminated by Gunderson and Holling's (2002) panarchy model and its nested adaptive cycles, where resilience is achieved by providing for change through loosening and reorganising connections between elements in the system.

Integrating Scrum With Other Design Approaches to Support Student Innovation Projects

Students who are innovating in a project-based context need appropriate frameworks to support applied research that is easily understandable, flexible to different contexts, and appropriate to their needs. Such support is particularly important when the research involves the development of a technology-related artifact, where students need empirical methods for the design and evaluation of that artifact, in addition to guidance in meeting the academic requirements of their courses. This chapter describes a Scrum-based approach for supporting innovations in learning contexts, extending previous proposals in the literature. The context of the research is two academic programs where students undertake innovative technology-based research projects. The new research model is designed to provide a better supporting framework to assist them to effectively manage their projects by integrating the adaptive cycles and ceremonies of the Scrum agile method with complementary concepts and phases from Design Thinking, Design Science, and Design-Based Research.

Sustainability and Resilience in Smart City Planning: A Review

Urban planning is recognized as an interaction between the state and society, which aims to articulate public policies in the territory, facilitating their administration in favor of greater development and well-being of society. However, this interaction becomes complex because consumption demands increase, and the needs of the community exceed the capacity of the urban ecosystem to supply them, hindering its sustainable functionality. With this panorama, it becomes relevant to study urban planning from a sustainable environmental planning perspective, based on four topics: urban planning, sustainability, resilience and smart cities. The methodology used is based on a bibliometric study through a PRISMA adjustment to 87 articles, supported by VOSviewer® to construct and visualize the co-occurrence networks of important terms extracted from a body of scientific literature. The main result is to consider cities with a complex systems approach that works like a gear, that is, there is a connective element between inter- and intra-urban processes. This relationship is the key factor that allows understanding their synchronization, stating that the deepening of each of these topics is crucial to the ideal of a territorial administration through time scales, by means of adaptive cycles, allowing to provide new tools to concepts such as carrying capacity and the measurement of the environmental footprint.

Persistent broken chromosome inheritance drives genome instability

Persistent DNA damage arising from unrepaired broken chromosomes or telomere loss can promote DNA damage checkpoint adaptation, and cell cycle progression, thereby increasing cell survival but also genome instability. However, the nature and extent of such instability is unclear. We show, using Schizosaccharomyces pombe, that inherited broken chromosomes, arising from failed homologous recombination repair, are subject to cycles of segregation, DNA replication and extensive end-processing, termed here SERPent cycles, by daughter cells, over multiple generations. Following Chk1 loss these post-adaptive cycles continue until extensive processing through inverted repeats promotes annealing, fold-back inversion and a spectrum of chromosomal rearrangements, typically isochromosomes, or chromosome loss, in the resultant population. These findings explain how persistent DNA damage drives widespread genome instability, with implications for punctuated evolution, genetic disease and tumorigenesis.One Sentence SummaryReplication and processing of inherited broken chromosomes drives chromosomal instability.

Supply chain resilience: an adaptive cycle approach

PurposeThe purpose of this paper is to develop a conceptual framework for extending an understanding of resilience in complex adaptive system (CAS) such as supply chains using the adaptive cycle framework. The adaptive cycle framework may help explain change and the long term dynamics and resilience in supply chain networks. Adaptive cycles assume that dynamic systems such as supply chain networks go through stages of growth, development, collapse and reorientation. Adaptive cycles suggest that the resilience of a complex adaptive system such as supply chains are not fixed but expand and contract over time and resilience requires such systems to navigate each of the cycles’ four stages successfully.Design/methodology/approachThis research uses the adaptive cycle framework to explain supply chain resilience (SCRES). It explores the phases of the adaptive cycle, its pathologies and key properties and links these to competences and behaviors that are important for system and SCRES. The study develops a conceptual framework linking adaptive cycles to SCRES. The goal is to extend dynamic theories of SCRES by borrowing from the adaptive cycle framework. We review the literature on the adaptive cycle framework, its properties and link these to SCRES.FindingsThe key insight is that the adaptive cycle concept can broaden our understanding of SCRES beyond focal scales, including cross-scale resilience. As a framework, the adaptive cycle can explain the mechanisms that support or prevent resilience in supply chains. Adaptive cycles may also give us new insights into the sort of competences required to avoid stagnation, promote system renewal as resilience expands and contracts over time.Research limitations/implicationsThe adaptive cycle may move our discussion of resilience beyond engineering and ecological resilience to include evolutionary resilience. While the first two presently dominates our theorizing on SCRES, evolutionary resilience may be more insightful than both are. Adaptive cycles capture the idea of change, adaptation and transformation and allow us to explore cross-scale resilience.Practical implicationsKnowing how to prepare for and overcoming key pathologies associated with each stage of the adaptive cycle can broaden our repertoire of strategies for managing SCRES across time. Human agency is important for preventing systems from crossing critical thresholds into imminent collapse. More importantly, disruptions may present an opportunity for innovation and renewal for building more resilience supply chains.Originality/valueThis research is one of the few studies that have applied the adaptive cycle concept to SCRES and extends our understanding of the dynamic structure of SCRES

How a Deadly Pandemic Cleared the Air: Narratives and Practices Linking COVID-19 with Air Pollution and Climate Change

The recent COVID-19 pandemic revealed the intricate connections between human and planetary health. Air pollution cleared over the countries ordering lockdowns of nonessential businesses to flatten the curve of the pandemic. The links between pandemics and pollution are not obvious at first, yet the two phenomena have several characteristics in common. Both pandemics and pollution originate from specific locations but then spread globally, and both are human-induced rather than natural–hazard disasters. I examine narratives and practices linking COVID-19 with air pollution and climate change as the pandemic unfolds. I compare these findings with research on the Black Death plague in Europe and the air pollution in China’s Haze City. Applying the analytical frameworks from these two studies, I analyze media articles and reports on COVID-19 to explore risk experience, stress behaviours, and resistant discourse during the adaptive cycles of the pandemic to gain insights into current and future changes to sustainability.
