Tracking the environmental impacts of production, use, and disposal of products (e.g., goods, and services) have been an important issue in the global economy. Although Life Cycle Assessment (LCA) is a widely applied method to track these environmental impacts and support policies, it has certain limitations and an isolated way of evaluating the environmental impacts with no consideration of social and economic impacts and mechanisms. To overcome the limits of current LCA, three mechanisms have been proposed in the literature: (1) broadening the indicators by including social and economic indicators in addition to the environmental impacts; (2) broadening the scope of analysis from product-level assessment to national and global levels; (3) deepening the assessment by inclusion of more mechanisms to account for interrelations among the system elements, uncertainty analysis, stakeholder involvement, etc. With these developments, LCA has been evolving into a new framework called Life Cycle Sustainability Assessment (LCSA). Practical application of LCSA requires integration of various methods, tools, and disciplines. In this study, a comprehensive literature review is conducted to investigate recent developments, current challenges, and future perspectives in the LCSA literature.

According to the review, a high number (40%) of LCSA studies are from the environmental science discipline, while contributions from other disciplines such as economics (3%) and social sciences (9%) are very low. On broadening the scope of analysis, 58% of the studies are product-level works, while 37% quantified the impacts at national level and achieved an economy-wide analysis, and only 5% of the studies were able to quantify the global impacts of products using LCSA framework. Furthermore, current applications of LCSA have not considered the rebound effects, feedback mechanisms, and interrelations of the system of interest sufficiently. To address these challenges, we present a complete discussion about the overarching role of systems thinking to bring tools, methods and disciplines together, and provide practical examples from the earlier studies that have employed various system-based methods. We discuss the importance of integrated system-based methods for advancement of LCSA framework in the following directions: (1) regional and global level LCSA models using multi-region input-output analysis that is capable of quantitatively capturing macro-level social, environmental, and economic impacts; (2) dealing with uncertainties in LCSA during multi-criteria decision-making process and expert judgments in weighting of LCSA indicators; and (3) integration of system dynamics modeling to reveal complex interconnections, dependencies, and causal relationships between sustainability indicators.

The ways in which we travel—by what mode, for how long, and for what purpose—can affect our sense of happiness and well-being. This paper assesses the relationships between measures of the sustainability of transportation systems in U.S. metropolitan areas and subjective well-being. Associations between self-reported happiness levels from the Gallup Healthways Well-being Index and commute data were examined for 187 core-based statistical areas (CBSA). We also supplement this quantitative analysis through brief case studies of high- and low-performing happiness cities. Our quantitative results indicate that regions with higher commute mode shares by non-automobile modes generally had higher well-being scores, even when controlling for important economic predictors of happiness. We also find that pro-sustainable transportation policies can have implications for population-wide happiness and well-being. Our case studies indicate that both high and low scoring happiness cities demonstrate a dedicated commitment to improving sustainable transportation infrastructure. Our study suggests that cities that provide incentives for residents to use more sustainable commute modes may offer greater opportunity for happiness than those that do not.

This study assesses whether multifunctional edible landscaping business models provide a sufficient business case at enterprise and city scales to justify widespread implementation. First, semi-structured interviews were conducted with four landscaping entrepreneurs, and the information obtained from the interviews was utilized to carry out a business model comparison with the Business Model Canvas framework. The comparison showed that the landscaping enterprises using multifunctional edible landscaping methods possessed a greater range of value propositions and revenue streams, enhancing their competitive advantage. Second, a GIS landscape analysis of seven Phoenix metro area cities was carried out to identify landscapes that were suited for becoming multifunctional edible landscapes. The GIS analysis identified single family residential, residential recreational open space, municipal parks, and municipal schools as being suitable landscapes, and that the area of these landscapes in the seven cities exceeded 180,000 acres. Third, scenarios were created using interview and GIS data to estimate potential value creation and return on investment of implementing multifunctional edible landscaping in the cities of interest. The scenarios found that the potential value creation of edible landscaping ranged between $3.9 and $66 billion, and that positive return on investment (ROI) could be achieved in 11 out of 12 scenarios within one to five years. Finally, the paper concludes by discussing potential long-term implications of implementing multifunctional edible urban landscaping, as well as possible future directions for multifunctional landscaping business model development and research.

Sustainable development efforts in urban areas often focus on understanding and managing factors that influence all aspects of health and wellbeing. Research has shown that public parks and green space provide a variety of physical, psychological, and social benefits to urban residents, but few studies have examined the influence of parks on comprehensive measures of subjective wellbeing at the city level. Using 2014 data from 44 U.S. cities, we evaluated the relationship between urban park quantity, quality, and accessibility and aggregate self-reported scores on the Gallup-Healthways Wellbeing Index (WBI), which considers five different domains of wellbeing (e.g., physical, community, social, financial, and purpose). In addition to park-related variables, our best-fitting OLS regression models selected using an information theory approach controlled for a variety of other typical geographic and socio-demographic correlates of wellbeing. Park quantity (measured as the percentage of city area covered by public parks) was among the strongest predictors of overall wellbeing, and the strength of this relationship appeared to be driven by parks’ contributions to physical and community wellbeing. Park quality (measured as per capita spending on parks) and accessibility (measured as the overall percentage of a city’s population within ½ mile of parks) were also positively associated with wellbeing, though these relationships were not significant. Results suggest that expansive park networks are linked to multiple aspects of health and wellbeing in cities and positively impact urban quality of life.

The widespread environmental degradation characterizing the Anthropocene is a call to address a deteriorating human-nature relationship. For much of history, humans have been deeply connected with and in respect of nature both physically and psychologically, and this bond can be renewed. Doing so is especially important for future generations, as modern youth have less opportunities to experience the natural world and more opportunities to experience the virtual world. A lack of nature connectedness in our youth has clear implications for sustainability and underscores the need for interventions aimed at reconnecting youth with nature. Primary and secondary education is a particularly valuable leverage point for such interventions, and nature-based school landscapes may be a valuable tool in strengthening the human-nature relationship and reconnecting youth with nature. While studies have indirectly linked garden-based learning and connection with nature in youth, research has not yet directly explored the relationship between the two.

My research explores 12th grade students attending Desert Marigold School in South Phoenix. Desert Marigold practices Waldorf educational philosophy with the school’s garden as a primary teaching tool and recreational space. I used arts-based methods to give students an opportunity to visually communicate their perspectives of the school’s landscape through photography and artistic renderings. Students then verbally described and discussed their media in a series of group interviews. Data were then coded and analyzed for themes of connection with nature expressed in the literature. The results illustrate that students connect with nature in a variety ways through the school’s landscape, demonstrating potential for enhanced sustainability outcomes in education.

City governments are increasingly interested in the concept of urban resilience. While theoretical debates continue to develop and critique the value of ‘urban resilience,’ a growing number of cities are organizing policies and projects around the concept. Building urban resilience is viewed as a key concern for cities facing, in particular, climatic threats –although other urban challenges and equity concerns are increasingly prioritized. Support from city leadership and large funding opportunities, such as the Rockefeller Foundation’s 100 Resilient Cities program, have encouraged some leading cities to create and manage city-wide resilience strategies. Yet pioneering cities have few guideposts to institutionalize resilience. This research evolved out of conversations with city officials in Portland, OR who were interested to learn how other cities were organizing resilience work. We explore how urban resilience is being structured and coordinated in 19 North American cities, focusing on emerging definitions, organizational structures, internal and external coordination efforts, and practitioners’ insights. We situate our findings on emerging governance approaches and lessons learned within the current urban resilience literature on governance by reviewing 40 academic papers and identifying 6 recurrent factors for effective governance. Additionally, we conducted 19 semi-structured interviews with North American resilience practitioners to describe emerging organization trends and share lessons from practice. Based off our interviews, we propose 5 key findings for structuring resilience work in cities effectively. These include: establishing a clear, contextual definition and scope, bringing communities into the process, championing the agreed-upon vision, balancing a centralized and dispersed approach, and recognizing tradeoffs in organizational placement. This research provides practitioners with insights to help facilitate resilience work within their cities and contributed to the scholarly debate on moving resilience theory toward implementation.
