Although the term “sustainability” did not gain traction until the 1980s, concerns about the consequences of transportation technology started long before. This paper reviews the literature on urban transportation sustainability using three frameworks. First, urban transportation can be unsustainable environmentally, economically, and socially (the three pillars of sustainability). Second, sustainable strategies tend to fall into two paradigms. Sustainable Transport Technology improves current patterns of modes and trips by consuming less resources and generating less waste. Sustainable Travel Behavior and Built Environment takes a more holistic approach that targets more sustainable travel choices, recognizing that changes in the built environment that currently constrains those choices are also essential. Third, the Planner’s Triangle helps explain commonly encountered situations where inherent tradeoffs can impede win-win-win strategies across environmental, economic, and social domains. The paper concludes with future research directions and concluding thoughts about urban transportation and sustainability.

Many communities have been marginalised in the ongoing policy and planning debates surrounding transportation electrification, even though well allocated charging infrastructure is essential for the environmental and societal benefits of Electric Vehicles (EVs) to be realised. This scoping review aims to synthesise the current state of knowledge and gaps surrounding transportation equity in EV charging research. Following PRISMA-Scr protocols, a literature search is conducted to locate articles that explicitly or implicitly discuss EV charging equity. Our review finds that research on charging equity is nascent and lacking in clear normative evaluations of equity compared to the wider body of transportation equity literature. Only slightly more than one-in-four of an identified 37 articles discuss equity and justice explicitly. Equity perspectives in charging research are dominated by North American and European perspectives, with limited perspectives from the rest of the world. Charging incentivisation schemes and planning efforts may not be equity focused and may favour wealthier individuals, and there are differences in the charging needs and desires of high adoption groups compared to low adoption groups. These findings, however, often come from geographically and philosophically limited contexts and there are gaps in the literature for new methodological and topical contributions to this area.

Urban expansion, a defining feature of the contemporary era, presents both challenges and opportunities for sustainable development

Despite the growing interest in organic farming, its practice remains limited because of its lower productivity relative to conventional farming. Land suitability evaluation for organic crops can potentially improve productivity, and thus the economic viability of organic farming. The best analytical procedures for such evaluations have not yet been fully explored. This article addresses the evaluation of land suitability of present agricultural lands for organic agriculture of rain-fed winter wheat using Duplin County, North Carolina, a location economically dependent on agriculture, as a case study. A novel land suitability evaluation procedure is developed combined with seventeen suitability criteria from five principal categories including climatic parameters, soil characteristics and qualities, soil chemistry, soil organic matter and fertility, and flood and erosion hazards by using geographic information systems (GIS), multicriteria analysis, and the square root method. Our analysis demonstrates that although 18.6 percent of agricultural lands in Duplin County are highly suitable for organic winter wheat production, a large proportion (76.8 percent) of agricultural lands are also moderately suitable. The method of suitability analysis used in this research, which allows specific consideration of soil organic matter and fertility as particularly critical factors for organic farming, can be easily exported to other locations, for similar applications.
