    The structure, function, and services of urban ecosystems evolve over time scales from seconds to centuries as Earth’s population grows, infrastructure ages, and sociopolitical values alter them. In order to systematically study changes over time, the concept of “urban evolution” was proposed. It allows urban planning, management, and restoration to move beyond reactive management to predictive management based on past observations of consistent patterns. Here, we define and review a glossary of core concepts for studying urban evolution, which includes the mechanisms of urban selective pressure and urban adaptation. Urban selective pressure is an environmental or societal driver contributing to urban adaptation. Urban adaptation is thesequential process by which an urban structure, function, or services becomes more fitted to its changing environment or human choices. The role of water is vital to driving urban evolution as demonstrated by historical changes in drainage, sewage flows, hydrologic pulses, and long-term chemistry. In the current paper, we show how hydrologic traits evolve across successive generations of urban ecosystems via shifts in selective pressures and adaptations over time. We explore multiple empirical examples including evolving: (1) urban drainage from stream burial to stormwater management; (2) sewage flows and water quality in response to wastewater treatment; (3) amplification of hydrologic pulses due to the interaction between urbanization and climate variability; and (4) salinization and alkalinization of fresh water due to human inputs and accelerated weathering. Finally, we propose a new conceptual model for the evolution of urban waters from the Industrial Revolution to the present day based on empirical trends and historical information. Ultimately, we propose that water itself is a critical driver of urban evolution that forces urban adaptation, which transforms the structure, function, and services of urban landscapes, waterways, and civilizations over time

    Which economic model for a water-efficient Europe? Report of a CEPS Task Force. CEPS Task Force Report, 27 November 2012

    Get PDF
    This CEPS Task Force Report focuses on how to improve water efficiency in Europe, notably in public supply, households, agriculture, energy and manufacturing as well as across sectors. It presents a number of recommendations on how to make better use of economic policy instruments to sustainably manage the EU’s water resources. Published in the run-up to the European Commission’s “Blueprint to Safeguard Europe’s Waters”, the report contributes to the policy deliberations in two ways. First, by assessing the viability of economic policy instruments, it addresses a major shortcoming that has so far prevented the 2000 EU Water Framework Directive (WFD) from becoming fully effective in practice: the lack of appropriate, coherent and effective instruments in (some) member states. Second, as the Task Force report is the result of an interactive process involving a variety of stakeholders, it is able to point to the key differences in interpreting and applying WFD principles that have led to a lack of policy coherence across the EU and to offer some pragmatic advice on moving forward

    Eco‐Holonic 4.0 Circular Business Model to  Conceptualize Sustainable Value Chain Towards  Digital Transition 

    Get PDF
    The purpose of this paper is to conceptualize a circular business model based on an Eco-Holonic Architecture, through the integration of circular economy and holonic principles. A conceptual model is developed to manage the complexity of integrating circular economy principles, digital transformation, and tools and frameworks for sustainability into business models. The proposed architecture is multilevel and multiscale in order to achieve the instantiation of the sustainable value chain in any territory. The architecture promotes the incorporation of circular economy and holonic principles into new circular business models. This integrated perspective of business model can support the design and upgrade of the manufacturing companies in their respective industrial sectors. The conceptual model proposed is based on activity theory that considers the interactions between technical and social systems and allows the mitigation of the metabolic rift that exists between natural and social metabolism. This study contributes to the existing literature on circular economy, circular business models and activity theory by considering holonic paradigm concerns, which have not been explored yet. This research also offers a unique holonic architecture of circular business model by considering different levels, relationships, dynamism and contextualization (territory) aspects

    Nanotechnology, Industry Competitiveness and University Strategies: the Case of the UWS Nanotechnology Network in South-West Sydney

    Get PDF
    University-industry alliances have long been pursued by public funded programs hoping to boost innovation spillovers in a geographical or cognitive area of research-strength by universities. However, there is still a lack of industry-university cooperation in many fields while at the same time the benefits of universities to their regions’ knowledge intensity is firmly advocated (Acs 2004, Martinez-Fernandez & Leevers 2004, Martinez-Fernandez 2004)). The issue is not limited to the dissemination of knowledge, a traditional role of universities, but to introducing change into the region’s innovation system through activities that increase industry competitive advantage. Results from a project conducted in South-West Sydney from 2003 to 2005 shows that active industry engagement by Universities offering specific expertise in frontier technologies has a positive effect in university-industry cooperation if compared with other technologies well established in the private sector. The project results also show that the role of Universities as active facilitators of industry engagement in frontier technologies is a critical element in the regional/local innovation system where the university operates. The paper discusses first the context of the emergence of the UWS Nanotechnology Network as a sophisticated knowledge intensive service activity led by the University. Secondly the paper discusses the particular case of nanotechnology as a science in an early path and the role of universities at this particular stage. Thirdly, the paper discusses the use and barriers of firms to nanotechnology applications and the role played by UWS during the duration of the project. Finally policy issues arise in relation to the role of the public education sector in the early promotion of frontier technologies. References Acs, Z. (2002) Innovation and the Growth of Cities.

    Defining And Measuring Green FDI: An Exploratory Review Of Existing Work And Evidence

    Get PDF
    This paper was developed at the request of the OECD Working Party of the Investment Committee to document efforts to date to define and measure green FDI and to investigate the practicability of various possible definitions, as well as to identify investment policy restrictions to green FDI. It does so by reviewing the literature and existing work on the contributions of FDI to the environment; by providing a two-part definition of green FDI; and by discussing various assumptions necessary to estimate the magnitude of \u27green\u27 FDI

    New horizons shaping science, technology and innovation diplomacy: the case of Latin America and the Caribbean and the European Union. EL-CSID Working Paper Issue 2018/20 ‱ August 2018

    Get PDF
    Europe and the world face a moment of transformation. The global financial crisis wiped out years of economic and social progress, exposed structural weaknesses in world economies and emphasised the importance of the real economies and strong industries. Modernisation and digitalisation of the industrial base together with the promotion of a competitive framework for industry through research, technology and innovation are drivers for recovery. Innovation, and particularly open innovation, is a key factor of global competitiveness. The European Commission (EC) addresses international cooperation policy in a wider framework and adapts to the evolving needs of partner countries at different stages of development (EC, 2018a). Latin America and the Caribbean countries’ (LAC) and the European Union’s (EU) cooperation on science, technology and innovation has a long history based on cultural roots and common concerns. They share a strategic bi-regional partnership, which was launched in 1999 and stepped up significantly in recent years. The two regions co-operate closely at international level across a broad range of issues and maintain an intensive political dialogue at all levels. EU-LAC relationships are moving from a traditional cooperation model towards a learning model, where sharing experiences and learning from innovations appear to be decisive (OECD, 2014). This paper focuses on the challenges that innovation nowadays poses to international relations and diplomacy. It is based on the evidence gained by the research team from participation in several EULAC projects, especially the ELAN Network project coordinated by TECNALIA, the INNOVACT project as well as other projects and activities
