Biophilic design has gained popularity in recent times that brings multiple benefits to the built environment including the ability to strengthen the weak human-nature connectedness in sustainable building designs. Premised on the notion of biophilia, biophilic design facilitates a sensory experience that could potentially influence psychology, cognition and behaviours. Measuring the biophilic impact and the quality of the design with its sensory experience is a challenge during the early design stages. Therefore, all existing tools developed to measure the biophilic quality, focused on completed projects in the industry. In academic settings design outcome is judged during the early design stage. Hence, the existing tools could not fully support biophilic quality evaluation. To fill this gap this study proposes a Biophilic Quality Matrix, to evaluate the biophilic quality that was developed adopting three techniques of 1) literature synthesis, 2) framework synthesis, and 3) expert knowledge that included a thorough analysing of the current tools. This novel matrix type tool comprises of 10 criteria and 10 intervention scales to capture the sensory experiences that could be adapted in both conventional and sustainable studios. It was developed allowing postgraduate students to use as a self-assessment tool to scaffold learning by facilitating for evaluative judgement. Two sample evaluations are given with a validation by tutors using an interrater rating method with 92% agreement for case 1 and 93% for case 2. The statistical analysis revealed that the Cohen's kappa was .804 for Case 1 and .823 for Case 2, both indicating a strong agreement level by the tutors. Therefore, this new tool can be used in design studios to evaluate the biophilic quality. Further, this matrix contains criteria that is commonly applicable biophilic design allowing to be used in industry for real projects both during design stage and after completion with systematic validation.

Globally, the rise of smart cities underscores the critical role of resident participation in advancing sustainable urban systems, particularly in managing waste during periods of transition. While technological innovations such as sensing and data analytics have garnered attention, the integration of these solutions with social dynamics remains underexplored. This study addresses this gap by investigating the dynamics of resident engagement in smart waste management during the transitional phase of landfill closures, using Yogyakarta, Indonesia, as a case study. The research aims to bridge the disconnect between technological advancements and community involvement, emphasizing their interplay in ensuring sustainable outcomes. Adopting a mixed-methods approach, this study integrates advanced computational intelligence with qualitative insights into behavioral drivers. Key elements of the methodological framework include sensing, learning, understanding, and acting, enabling a comprehensive exploration of the technological and human dimensions of waste management. Advanced predictive models analyze patterns in waste generation, optimizing system responsiveness and efficiency, while qualitative data reveal the critical role of education and tailored communication strategies in fostering resident participation. Findings demonstrate that combining cutting-edge technology with community-centric initiatives leads to significant improvements in waste management outcomes. Strategic educational campaigns and adaptive communication tailored to local contexts enhance public engagement and sustainable practices. Furthermore, the study underscores the importance of continuous learning and adaptive management, enabling urban planning frameworks to evolve in response to emerging challenges. This synergy between technology and civic participation is pivotal for the long-term success of smart city initiatives. The novelty of this research lies in its holistic integration of technological solutions and social dynamics, offering a scalable and adaptable model for smart waste management. By emphasizing the importance of adapting universal principles to local contexts, this study provides actionable insights for global smart city strategies, making it a pioneering contribution to urban sustainability.

The sustainability of agricultural trade: The case of South Africa

Cleaner Production Letters

Pub Date : 2025-01-07 DOI: 10.1016/j.clpl.2025.100092

Trade in agricultural products will be a crucial component of adaptive responses to global food insecurity and ensuring its sustainability is thus crucial. This is particularly important for resource scarce countries because agricultural trade allows for the virtual transfer of the resources required for production. This is important because agricultural production has significant resource requirements as well as substantial environmental, climatic and economic impacts. Assessing the sustainability of agricultural trade has proven to be a complex challenge due to a lack of frameworks available to comprehensively assess it and the ‘silo approach’ to resource management. To combat these problems new frameworks and analysis techniques which account for numerous sectors and impacts need to be developed. The objective of this paper was to provide and utilise such a framework to assess the sustainability of agricultural trade. To do this, the Water-Energy-Food Land-Economy-Climate framework was proposed. The framework was used in combination with a lifecycle analysis approach to assess the sustainability of agricultural trade in South Africa. Despite exporting 25% more agricultural products than they imported, the results showed that the production of South Africa's agricultural imports required 65% more water, 3% more energy, and 44% more land than exports. Further, imports generated 98% more CO₂ and 103% more PO₄ emissions than exports. Finally, South Africa was shown to generate 64% more economic value from their agricultural exports than their imports cost. Overall, the results show that according to the Water-Energy-Food Land-Economy-Climate framework used, and accounting for the South African resource context, the country had a sustainable agricultural trade mix.

This study examines the impact of the Thriving Futures 2023 event, which engaged the Dalhousie University (DAL) community located in Halifax, Nova Scotia, Canada, and residents from the broader Halifax area in exploring inclusive sustainable development pathways. Employing a mixed methods approach that included surveys, video interviews, and expressive arts, the research captures diverse perspectives from students, staff, faculty, and community members. Rooted in a transdisciplinary framework, the event wove together the 17 Rooms methodology with Indigenous and local knowledge systems. Through deep dialogues and collaborative activities focused on the Sustainable Development Goals (SDGs), the event cultivated meaningful engagement. Key findings reveal a strong enthusiasm and readiness within the academic community to advance sustainability efforts, alongside challenges such as limited structural incentives and insufficient university leadership support. This study underscores the critical role of inter- and transdisciplinary collaboration, inclusive leadership, and the integration of sustainability principles into university curricula and operations. By reflecting on the outcomes of Thriving Futures (2023), the research offers actionable strategies for embedding sustainable practices in higher education and contributes to the broader discourse on applying the SDGs in academic contexts.

Implementing a Digital Product Passport (DPP) for Electric Vehicle Batteries (EVBs) is crucial for fostering sustainability and circularity within the EVB value chain. While a growing number of related concepts are becoming available, the understanding of DPP-related stakeholder perceptions is limited. Therefore, this study evaluates the information requirements of EVB value chain actors, focusing on the importance, availability, and accessibility of specific information attributes necessary for the DPP. The study follows a mixed-method approach, beginning with qualitative data collection through literature reviews and expert consultations, followed by a survey (n = 46) targeting stakeholders across EVB lifecycle phases and the conduct of an importance-availability analysis. The results cover, firstly, a comprehensive list of 40 information attributes, divided into sustainability and circularity-related information and general information. Secondly, the study reveals the perceived importance and availability of these information attributes through the lens of actors from the Beginning of Line (BoL), End of Life (EoL), and Battery Second Use (B2U) phases. Also, it adds the specific perspectives of individual value chain actors - designers, B2U actors, and recyclers. Thirdly, a ranking of the most important actors for successfully implementing the DPP is presented. The results indicate a critical need for enhanced information availability and accessibility, particularly concerning sustainability and circularity-related data. This study provides theoretical and practical implications for sustainable EVB lifecycle management using DPPs.

Ecolabels and novel environmental assessment methods are increasingly being used to evaluate the environmental impacts of food items. Some ecolabels build on life cycle assessment, a standardised method for the environmental impact assessment of products over their entire life cycle. The major challenges of life cycle assessment include its complexity in application and result communication, as well as its data intensity. The aim of this study was to compare the methods behind ecolabels to traditional life cycle assessments for evaluating the environmental impacts of food products. To this end, we (1) categorised ecolabels, (2) identified criteria describing the suitability of existing ecolabels in evaluating the environmental impacts of food labels, (3) identified main challenges of the methods underlying ecolabels, and (4) evaluated the challenges based on the criteria to answer the research question. Among the challenges, we found that merging results obtained by different methods, such as life cycle impact assessment and bonus/malus point systems, to build a composite score can risk double counting. Furthermore, certain agricultural production methods are sometimes assumed to be more environmentally friendly than others without evidence. Environmental labels focusing on one or a few selected aspects of sustainability while ignoring other relevant issues can lead to burden shifting and should be avoided. Based on our findings, we conclude that ecolabels help consumers make more sustainable purchasing decisions and create business cases for companies as an incentive to mitigate impacts, while complex research questions should be addressed based on life cycle assessment.

Land restoration requires innovative approaches to prevent ongoing degradation and increase the functionality of land use. While land restoration has been studied extensively from the perspective of ecologists and local communities it is a topic that remains at the periphery of the financial economics literature, despite the global financial system’s centrality to the problem. This paper reviews the literature on financial instruments that are designed for land-based ecological restoration, extracts key learnings from this literature and deploys a functional perspective to better understand how financial instruments that aim to scale up land restoration activities can be mainstreamed within the global financial system. This paper presents a framework that promotes public channels to best direct public and private capital towards land restoration projects. Matching the supply of capital with a pipeline of spatially explicit and sometimes unique restoration solutions requires an architecture that can implement this coordination and aggregation function. This has the potential to mitigate transaction costs and improve transparency issues associated with monitoring and reporting. This framework is illustrated for an actual land restoration program underway in Europe.

The environmental impact of green trade and circular trade: Does urbanization matter?

Cleaner Production Letters

Pub Date : 2024-12-15 DOI: 10.1016/j.clpl.2024.100086

Urban areas are responsible for approximately two-thirds of global energy consumption and over 70% of greenhouse gas emissions, making them pivotal in addressing the global climate crisis. International efforts to achieve decarbonization have emphasized the role of trade in circular economy goods (or circular trade) and green trade composed of environmental goods and low-carbon technologies. Despite their significance, there is limited empirical evidence on how such trade impacts environmental outcomes, particularly when considering urbanization. This study addresses this research gap. Drawing on data from 54 economies between 2000 and 2018, the research employs a panel model incorporating theoretical transmission mechanisms and non-linear threshold effects. The findings reveal that while circular trade reduces environmental degradation, green trade initially exacerbates it. However, interaction models show that urbanization mitigates these negative impacts, enabling green trade to deliver better environmental outcomes. Panel threshold analysis supports these findings. These results challenge the prevailing narrative that green trade mitigates environmental degradation, shedding light on the complex dynamics between trade, urbanization, and environmental sustainability. This study highlights the need for tailored policies that consider a country’s urbanization level to maximize the environmental gains of green and circular trade.

Sustainability is a multifaceted endeavor that underscores the interdependence between society and nature. Its complexity arises from a delicate balance among four sustainability dimensions: economic, environmental, social, and durational. Achieving this equilibrium requires socio-technical changes, where actors and networks play pivotal roles. Actor-network theory is essential for addressing these aspects of sustainability, but a comprehensive overview of its contribution to sustainability literature is lacking. This paper provided the first systematic literature review of actor-network theory-based applications in sustainability, shedding light on current and future research directions. A bibliometric analysis of the literature from 1999 to 2024 using VOSviewer software and the Scopus database was conducted. The analysis of 197 relevant articles utilized performance metrics (productivity and citations) and science mapping techniques (co-citation analysis, bibliographic coupling, and co-word analysis). The findings reveal significant growth in publications, particularly in the last decade, as scholars have studied actor-network theory’s heterogeneity and symmetrical principles, along with the theory’s relational perspective in sustainability. The study specified four knowledge foundations of actor-network theory-based applications in sustainability, namely the nature-science perspective, multi-level perspective, cosmopolitan perspective, and meta-theoretical perspective, as well as four thematic clusters: urbanization, practices/tools, transitions, and industry. Future actor-network theory research in sustainability could emphasize the durational and socio-psychological dimensions, and focus on the field of social science computing. This paper significantly contributes to theory-based applications in sustainability and aids scholars in understanding actor-network theory while exploring critical unanswered questions about sustainability challenges and issues.

Global reports from the United Nations project significant deficits in achieving water and sanitation targets by 2030, emphasizing the need for advanced methodologies in ecosystem monitoring. This study examines the integration of the Random Forest machine learning algorithm with freely available satellite imagery and open-source tools to monitor Permanent Protected Areas (PPAs) in the Distrito Federal, Brazil, contributing to Sustainable Development Goal (SDG) 6, which prioritizes clean water and sanitation. The research adopts a methodological approach that classifies land use changes within PPAs, with a focus on riparian zones along riverbanks, utilizing high-resolution Sentinel-2 satellite data processed through the Google Earth Engine platform. The findings indicate a 6% increase in native vegetation within PPAs from 2015 to 2022, highlighting the utility of machine learning technologies in environmental monitoring. The Random Forest algorithm demonstrated robust performance, with classification accuracy rates ranging from 83% to 88% and Kappa coefficients between 0.73 and 0.84. These results underscore the method's ability to enhance data granularity and reliability, supporting informed decision-making in ecosystem management. This research contributes to advancements in environmental monitoring methodologies and aligns with international efforts to achieve SDG targets. Further studies should investigate the incorporation of additional machine learning models to improve monitoring accuracy and support sustainable development initiatives.
