A Systematic Review of the Measurement of Sustainable Diets

Sustainability has become an integral consideration of the dietary guidelines of many countries in recent decades. However, a lack of clear metrics and a shared approach to measuring the multiple components of sustainable diets has hindered progress toward generating the evidence needed to ensure the credibility of new guidelines. We performed a systematic literature review of empirical research studies on sustainable diets to identify the components of sustainability that were measured and the methods applied to do so. Two independent reviewers systematically searched 30 databases and other sources with the use of a uniform set of search terms and a priori exclusion criteria. In total, 113 empirical studies were included in the final review. Nearly all of the studies were focused on high-income countries. Although there was substantial heterogeneity in the components of sustainability measured, the estimated greenhouse gas emissions (GHGEs) of various dietary patterns were by far most commonly measured (n = 71 studies). Estimating the GHGEs of foods through various stages of production, use, and recycling with the use of the Life Cycle Assessment approach was the most common method applied to measure the environmental impacts of diets (n = 49 studies). Many components of sustainable diets identified in existing conceptual frameworks are disproportionately underrepresented in the empirical literature, as are studies that examine consumer demand for sustainable dietary alternatives. The emphasis in the literature on high-income countries also overlooks the production and dietary alternatives most relevant to low- and middle-income countries. We propose 3 methodological and measurement approaches that would both improve the global relevance of our understanding of sustainable diets and attend more completely to the existing multidimensional, multiscale conceptual framing of sustainable diets.

The Intersection of Planning, Urban Agriculture, and Food Justice: A Review of the Literature

Problem, research strategy, and findings: We draw on a multidisciplinary body of research to consider how planning for urban agriculture can foster food justice by benefitting socioeconomically disadvantaged residents. The potential social benefits of urban agriculture include increased access to food, positive health impacts, skill building, community development, and connections to broader social change efforts. The literature suggests, however, caution in automatically conflating urban agriculture’s social benefits with the goals of food justice. Urban agriculture may reinforce and deepen societal inequities by benefitting better resourced organizations and the propertied class and contributing to the displacement of lower-income households. The precariousness of land access for urban agriculture is another limitation, particularly for disadvantaged communities. Planners have recently begun to pay increased attention to urban agriculture but should more explicitly support the goals of food justice in their urban agriculture policies and programs. Takeaway for practice: We suggest several key strategies for planners to more explicitly orient their urban agriculture efforts to support food justice, including prioritizing urban agriculture in long-term planning efforts, developing mutually respectful relationships with food justice organizations and urban agriculture participants from diverse backgrounds, targeting city investments in urban agriculture to benefit historically disadvantaged communities, increasing the amount of land permanently available for urban agriculture, and confronting the threats of gentrification and displacement from urban agriculture. We demonstrate how the city of Seattle (WA) used an equity lens in all of its programs to shift its urban agriculture planning to more explicitly foster food justice, providing clear examples for other cities.

Bringing Practice to the Classroom: Using a Deliberative Learning and Case Study Approach to Teach International Planning:

More effective methods are needed to meet the Planning Accreditation Board’s requirement to teach all master’s students about the “global dimensions of planning.” Our survey of accredited US planning programs confirms that field-based courses, traditionally the most effective option, are costly and time-consuming and are therefore occasional, rather than regular, options for exposing students to international planning practice. Based on active learning theories, we suggest that a deliberative learning, case-based approach can facilitate many of the learning outcomes that make travel courses so attractive while also making internationally oriented pedagogies available to a wider range of students and programs.

“No Monuments, No Heroes” How Accidental Planners Established Bolivia’s Flagship Land Reform Project through Spatial, Facilitated, and Adaptive Strategies

The promises of land reform have always been as seductive as they are elusive. Bolivia’s experience is no different, but one forgotten case may still offer lessons today: a land distribution project initiated in San Julian in 1972. Through archival research and interviews, I argue that several understudied elements of the San Julian project—its spatial design, settler orientation program and implementation process—offer lessons about the role planners can play in structuring more successful land reform. Revisiting the lessons of past exemplars like San Julian is critical given renewed land reform efforts that appear to be replicating past failures.
