Broadly accepted categorical differentiations of urbanisation understand cities as well-defined objects containing urban spaces in contrast to their hinterlands. However, urbanisation's multidimensional complexity challenges these approaches the context increasing social issues marked by rapid expansion, uneven development, ways life, inequality, commodification, etc., that require fresh scientific answers grounded innovative empirical evidence. Here, we analysed population-based and land-use/land cover-based understandings urbanisation, looking at origins main shortcomings. Our analysis makes a generalised description spatial complexity, with an emphasis on problematic delimitation boundaries; occurring remote wild areas; missing third dimension. We discuss shortcomings based recent developments, providing reasons why approach needs be changed how. propose continuous indicator which is accumulation anthropogenic materials, physical, rather than or demographic characteristic. proposal allows socio-ecological systems' organisation, pursuing comparative studies across geographies times, informing globally generalisable patterns processes giving material body address claims for sustainable development.

From extraction to end‐uses and waste management: Modeling economy‐wide material cycles and stock dynamics around the world

Journal of Industrial Ecology, Journal Year: 2024, Volume and Issue: 28(6), P. 1464 - 1480

Published: Nov. 12, 2024

Abstract Material stocks of infrastructure, buildings, and machinery are the biophysical basis production consumption. They a crucial lever for resource efficiency sustainable circular economy. While material stock research has proliferated over last years, most studies investigated specific materials or end‐uses, usually not embedded into an economy‐wide perspective. Herein, we present novel version economy‐wide, dynamic, inflow‐driven model inputs, stocks, outputs ( MISO2 ), global, country‐level application. Currently, covers 14 supply chain processes from raw extraction to processing, trade, recycling, waste management, as well 13 end‐uses stocks. The derived database 23 20 stock‐building materials, across 177 countries 1900 2016. We find that total amount 1093 Gt in 2016, which majority residential (290 Gt) non‐residential buildings (234 Gt), civil engineering (243 roads (313 Gt). other nine covering stationary mobile machinery, short‐lived products, Gt. per capita highly unequally distributed around world, with one order magnitude difference between low‐ high‐income countries. Results agree similar global studies. Low data quality some domains, especially lower‐income sand gravel aggregates, warrant further attention.

How decarbonization and the circular economy interact: Benefits and trade‐offs in the case of the buildings, transport, and electricity sectors in Austria

Journal of Industrial Ecology, Journal Year: 2025, Volume and Issue: unknown

Abstract The widely heralded decarbonization of economies is a significant intervention in countries' societal metabolism, which eliminates the use fossil fuels but also requires renewing stocks such as buildings, vehicles, and power plants, turn materials energy. circular economy (CE) shifts country's metabolism toward less material demand, waste, emissions, moving away from linear resource flow pattern to one that narrows slows flows closes loops, order support climate protection. This article uses example Austria examine how CE interact transport, electricity sectors. We scenarios analyze contribution strategies achieve targets set by Austrian policy: (1) carbon neutrality 2040, (2) ambitious reductions consumption, (3) limiting annual land take. A scenario focusing on “decarbonization” alone reduces processed 7% compared reference scenario, associated with high risks: it large supplies green electricity, technology‐critical elements, smooth permitting procedures. “weak CE” shows little mitigating effects these risks. take are missed two scenarios.

Systematic Review of the Circular Economy Performance Assessment System Under International Management Paradigms

Revista de Gestão Social e Ambiental, Journal Year: 2024, Volume and Issue: 18(9), P. e05664 - e05664

Published: April 26, 2024

Objective: To present a Systematic Literature Review (SLR) on Performance Evaluation in the Circular Economy (PECE), addressing its temporal evolution and critically analyzing metrics found empirical studies. Theoretical Framework: The research starts from theoretical contributions characteristics of metric levels performance assessment systems, compared with management natural resources until we reach circular economy. Method: Utilization following Knowledge Development Process-Constructivist approach (ProKnow-C), assessing secondary data articles comprising Research Portfolio (RP). Results Discussion: literature presents variety circularity at different scales, yet there is predominance individual lack comprehensive focus Systems (PES). Implications: Identifies need for more integrative aligned CE principles capable encompassing multiple action. Future has potential to significantly enrich society by exploring development metrics, considering interaction between environmental performance. Originality/Value: Highlights growing concern (CE), identifies gaps understanding full impacts each supply chain, underscores robust principles.

Mission-Oriented Research and Theory of Change: Driving Australia’s Transition to a Circular Economy

Circular Economy and Sustainability, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 20, 2024

Abstract Australia’s linear economic system hinders the collective pursuit of sustainability, equity, and well-being. As demands for housing, food, energy, transportation, goods escalate, transitioning to a circular economy becomes imperative. Such transition necessitates transformation in business governance models, as well cultural shifts, foster sustainable material flows. The proposed change will likely unfold five phases: envisioning future, evaluating options trade-offs, initiating local actions, amplifying national efforts, solidifying global agreements. This shift occur within context significant technical, environmental, social, megatrends, each phase is overlap with next, some phases occurring concomitantly ongoing. It reshape socio-technical systems social practices that fulfil our essential needs. Moreover, this process inherently circular, characterised by continuous cycles learning, adaptation, risk management.
