In this study, we aim to identify social typologies of pedestrian crashes considering demographics, health impacts, involved vehicle, temporality of the collision, and place of impact in Hermosillo, Mexico. A socio-spatial analysis was performed by using local urban planning information and vehicles-pedestrian crashes records collected by the police department (N = 950) between 2014 and 2017. Multiple Correspondence Analysis and Hierarchical Cluster Analysis were used to determine typologies. Geographical distribution of typologies was obtained with spatial analysis techniques. The results suggest there are four typologies, which portray the physical vulnerability of pedestrians, which reflect the vulnerability to collisions associated to the variables age, gender, and street speed limits. Findings show that children are more likely to be injured during weekends in residential zones (Typology 1), while older females are more likely to be injured during the first three days of the week (Monday – Wednesday) in the downtown area (Typology 2). Injured males during the afternoon in arterial streets represented the most frequent cluster (Typology 3). Also, males were likely to be severely injured by heavy trucks during nighttime in peri-urban areas (Typology 4). These findings indicate that vulnerability and risk exposure vary according to the type of pedestrian involved in the crash, which are linked to the types of places they visit. The design of the built environment plays a major role in the number of pedestrian injuries particularly when it favors motor vehicles over pedestrians or non-motorized vehicles. Because traffic crashes are considered preventable events, cities must embrace a diversity of mobility modes and incorporate the appropriate infrastructures that safeguard the lives of all their travelers, especially pedestrians.

Many cities are turning to greening efforts to increase resilience, but such efforts often favor privileged groups, thereby resulting in injustices. In this systematic review, we analyze 71 place-based studies of green infrastructure (GI) justice in cities worldwide. We draw from environmental justice scholarship, as well as climate and water justice literature to assess the state-of-the-art knowledge of urban GI justice. We examine the way GI is researched to improve our understanding of the types of injustices that exist in GI planning, siting, and implementation, providing rich insights into why injustices exist and pathways to address GI injustice. We find that research on GI justice in cities is growing and expanding its scope in terms of both the types of justice issues analyzed, and the groups of people excluded from the benefits of GI. We find that GI injustice stems from a history of unequal investment and non-participatory decision-making processes, where the unequal distribution of GI is only the “tip of the iceberg”. To address GI injustice around distribution, cities would have to offset a decades-long lack of investment and inclusivity in decision-making processes. Pathways to achieve GI justice point to assessing unbalanced power structures, directing continuous funding to community engagement programs and greening efforts, leveraging existing infrastructure through the multifunctionality of GI, and dedicating funding mechanisms for safety and maintenance. Interdisciplinary and transdisciplinary research is needed to integrate the different dimensions of GI that are tailored to the community on the ground, and to monitor progress toward justice.

Blue and green infrastructure (BGI) is increasingly viewed as a promising solution to promoting a shift beyond traditionally engineered “grey” approaches towards more socially and environmentally sustainable infrastructure systems. The specific insights of geographical scholarship on how to address issues of processes, scale, and place in BGI design, implementation, and long-term management would help unlock the potential for BGI to be appropriate and inclusive, as well as support environmentally sound solutions. In this paper we unpack issues of processes for inclusive decision-making to design and implement BGI projects that can advance sustainable development. We present an assessment framework and its application to two case studies that highlight the potential for better alignment of BGI projects to the three pillars of sustainable development and that reveal key research challenges that geographical scholarship could address. We believe that co-produced geographical research in this domain is well placed to tackle these research challenges.

Societies across the globe strive to achieve water security—that is, assure access to sufficient water of acceptable quality for humans and the environment for changing, sustainable societies and ecosystems. But rapid and significant changes in environmental and social systems complicate attempts to assure water-secure conditions. This challenge is further magnified by transboundary conditions—while landscapes and physical processes disregard political borders, human institutions managing these resources often lack the traditions and capital for ensuring resilient, community-based responses to water shortage and contamination. This review highlights how features of community resilience contribute to enhancing transboundary water security using nine examples from the U.S.–Mexico border region. The cases demonstrate how public participation, adaptivity and flexibility, and social mobilization to promote equity and justice help to nurture and maintain community resilience, to the benefit of transboundary water security.

Highlights • The U.S. and Mexico have engaged in hydrodiplomacy for more than 75 years. • Treaties and binational institutions are strong foundations to ground and guide hydrodiplomacy efforts. • Adaptive governance principles have been important to achieving the major turning points in U.S.-Mexico hydrodiplomacy., The United States and Mexico have engaged in hydrodiplomacy—a practice of transboundary water management that blends water diplomacy and science diplomacy--for more than 75 years, since the adoption of the Treaty of 1944 and the creation of the International Boundary and Water Commission. We examine six major turning points in U.S.-Mexico hydrodiplomacy to ascertain the key factors in the region’s history of resolving transboundary water issues. We find that recognized adaptive governance indicators—such as social learning, sustained relationships, flexible governance mechanisms, and state and non-state networks are essential elements of hydrodiplomacy. Our research suggests that robust and foundational institutions comprise another key indicator of adaptive governance specifically in transboundary contexts. A commitment to both science and diplomacy have been important components underlying the effectiveness of hydrodiplomacy in the border region. Binational networks involving diverse state and non-state actors at multiple scales have increasingly played a pivotal role in shaping desirable hydrodiplomatic outcomes in the region.

Multifunctional and connected green infrastructure (GI) systems have been linked to urban resilience. Although there have been significant scholarly efforts to assess resilience and to evaluate the benefits of GI, it remains unclear the degree in which GI efforts enhance resilience. Following theoretical frameworks that study coupled infrastructure systems, this paper explores the state of the art on the contribution of GI to urban resilience from multiple dimensions: (1) policy - that promotes the adoption of GI, (2) performance - assessment of GI impacts on water infrastructure systems resilience, (3) connectivity - evaluation of human and wildlife movement through GI, and (4) social - community cohesion as a result of GI efforts. We argue that beyond their individual contributions to supporting urban resilience, the interactions across the various dimensions are key to enhancing resilience. Ultimately, participatory processes are needed to assess resilience originating from GI systems and avoid injustice.

In this study we analyse how three cities in the arid Americas have addressed urban growth while facing water scarcity: Hermosillo, Mexico; Mendoza, Argentina; and Tucson, USA. We use the urban water security framework to examine five domains of water management: sociodemographic, economic, technological, ecological and governance (SETEG). Our analysis indicates that, in spite of water scarcity, urban growth has been promoted in the three cities. We argue that this expansion, although encouraged for economic development, is not sustainable in the long term. In the three cities, groundwater plays a major role in water supply, but growth has negatively affected riparian ecosystems, the health of the aquifers and access to domestic water. In order to pursue water security, several options are essential to enhance social?ecological system resilience. These include limits or reduction of urban expansion, reuse of treated effluent for riparian conservation, and community conservation efforts such as rainwater harvesting and other green infrastructure practices.

Urban resilience emerges not only from ‘what’ is done in relation to critical infrastructure systems, but in the ‘how’ of their conception, co-creation and integration into complex socio-ecological-technical systems. For green infrastructure, where ownership and agency may be distributed amongst organisations and diverse communities, inclusiveness and appropriateness require embedding in engineering assessments of green infrastructure and resilience. Through consideration of past, present and future engineering and resilience assessments – from monetising, through greening, to humanising – this paper examines the ways in which GI may be or has already contributed to enhancing urban resilience and types of assessment and indicators that have been or could be used. We suggest that enhancing visibility of the ‘whos’ (individuals, communities) is crucial to fully diversifying assessments. We also suggest some ideas for additional indicators and assert that co-production of future indicators needs to be undertaken with appropriate professionals (e.g. social impact assessment professionals).

Climate change, population growth, and declining federal budgets are threatening the health of ecosystems, and the services they provide. Under these changing conditions, managing landscapes and resources assumes new and unprecedented challenges. Adaptive management has been identified as a natural resource management approach that allows practitioners to incorporate change and uncertainty into decision-making through an iterative process that involves long-term monitoring and continued review and adjustment of management actions. However, the success of these efforts in watershed health relies on the collective and sustained monitoring of indicators, which is seldom studied. The purpose of this analysis is to examine (1) the practical challenge of choosing a list of indicators for long-term monitoring, (2) the negotiation process among stakeholders around the selection and interpretation of indicators, and (3) the communication tools that can be used to convey the assessment’s results and findings. To do this, we analyze our ongoing work in the Cienega Watershed in southern Arizona. Our analysis shows that the selective use of indicators, regular assessment and review, and establishment of partnerships among stakeholders are all important elements in establishing effective adaptive management efforts. The selection of indicators and data sources is a moving target that requires regular consensus and review among stakeholders. The assessment itself is also a powerful engagement tool with the public at large, providing legitimacy and support to land management decision-making. Here, we outline some lessons learned that can be transferred to other cases and identify potential barriers for engagement, decision-making, and project success.

Innovation in urban water systems is required to address drivers of change across natural, built, and social systems, including climate change, economic development, and aged infrastructure. Water systems are complex socio-technical systems that interact with biophysical systems to supply and reclaim water. We present a vision for enhancing urban water system resilience through a net zero urban water (NZUW) approach, which meets the needs of a given community with a locally available and sustainable water supply, without detriment to interconnected systems or long-term water supply. NZUW is an integrative approach with progressive targets assessed using a quantitative framework to expand adaptive and responsive solutions for urban water self-sufficiency. Decision makers can use NZUW to understand trade-offs between future interventions to urban water systems across spatial and temporal scales. We present the overall NZUW approach, drivers of change, applications, and research gaps.

This is a chapter about the advent and adoption by water scholars of a new term, “water security.” How did this term appear, how is it defined, in which settings does it apply, what are its different facets and interpretations? Has it impacted water management and if so, how? The authors explore the discourse surrounding this term and the persons and institutions that have found it useful, channeled it, challenged it, and popularized it over the past century.

Transboundary waters are characterized by diverse and complex socio-politico-economic obstacles to effective water management. We examine five distinct cases in the arid Americas–in locations from the US–Mexico border to the Andes mountains–employing water security as a conceptual prism to unravel the multiple and varied attributes of transboundary water challenges. We describe how borders complicate water security in arid regions and explore how institutional arrangements and practices–within and across jurisdictions–respond to these challenges. We find that institutional capacity is needed on multiple levels for effective water management, and institutions must be responsive and flexible to change. Fil: Albrecht, Tamee R..

Water security has emerged as a major framing template in environmental governance and resource management. The term and underlying concepts have attracted the attention of governmental and nongovernmental organizations, private industry, and the academy in policy and practice. Notwithstanding the palpable rise in its use, a comprehensive understanding of how water security is conceptualized and employed in different contexts around the world is limited. We aim to address this gap, by assessing how water security is considered, articulated, and operationalized in place-based studies. We employ a two-part methodological approach that includes (1) a systematic analysis of 124 articles, books, and book chapters published between 2010-2015 using a standardized coding framework to examine trends and patterns in place-based water security research, and (2) an analysis of the treatment of governance as a subset of this body of research to reveal how water governance is framed and understood in place-based water security scholarship. We find broad diffusion of water security across geographic regions and scales, expansive framing of water security, and evolving approaches to indicator formulation. The narratives around future pathways for governance practices include the promotion of participatory processes, solutions that engage both quantitative and qualitative methods, and a mix of both hard- and soft-path approaches to achieve water security. The persistent diversity in perspectives and applications of water security suggests that scholars adapt the concept to the contexts of the cases they are studying. The variation in how water security is utilized in different regions and spatial scales underscores the importance of incorporating community context in how we understand and employ water security. By empirically assessing the diversity and utility of water-security analyses, highlighting regional differences, and tracing evolving conceptions over time, our research can inform future project design, policy-making, and management from the international to the local levels.

Climate change is posing emerging threats to people and the environment, particularly in arid regions. However, some groups are more vulnerable than others, depending on their levels of exposure, sensitivity and adaptive capacity, which are determined by climatic and non-climatic factors. In water-scarce environments, water policies become key non-climatic factors that affect vulnerability yet enable modifications if their impacts unintentionally exacerbate vulnerability. Therefore, it is necessary to analyze the impacts of water policies on vulnerability, particularly for disadvantaged groups. In this paper, we analyze four cases in the arid Americas that illustrate an array of challenges at different scales and across the rural-urban continuum: (1) irrigated oases in Mendoza, Argentina, where groundwater and surface water management are disconnected; (2) rural communities in central Sonora, Mexico, where local water rights have been transferred to large scale mining; (3) peri-urban marginalized neighborhoods in Hermosillo, Mexico, where competition for water is driving changes in land use; and (4) underserved communities in Tucson, Arizona, USA who are left behind in a rainwater harvesting movement. Our analysis shows that water policies in arid regions interact with land and neoliberal policies between sectors across different scales, exacerbating vulnerabilities disproportionately in less privileged groups and enhancing disparities. Here, we offer recommendations for more inclusive policymaking processes that can build capacity, protect the livelihoods of disadvantaged groups, and reduce their vulnerability to climate change.

Addressing wicked problems challenging water security requires participation from multiple stakeholders, often with conflicting visions, complicating the attainment of water-security goals and heightening the need for integrative and effective science-policy interfaces. Sustained multi-stakeholder dialogues within science-policy networks can improve adaptive governance and water system resilience. This paper describes what we define as “dialogic science-policy networks,” or interactions -- both in structural and procedural terms -- between scientists and policy-makers that are: 1) interdisciplinary, 2) international (here, inter-American), 3) cross-sectoral, 4) open, 5) continual and iterative in the long-term, and 6) flexible. By fostering these types of interactions, dialogic networks achieve what we call the 4-I criteria for effective science-policy dialogues: inclusivity, involvement, interaction, and influence. Here we present several water-security research and action projects where some of these attributes may be present. Among these, a more comprehensive form of a dialogic network was intentionally created via AQUASEC, a virtual center and network initially fostered by a series of grants from the Inter-American Institute for Global Change Research. Subsequently, AQUASEC has significantly expanded to other regions through direct linkages and additional program support for the International Water Security Network, supported by Lloyd's Register Foundation and other sources. This paper highlights major scientific and policy achievements of a notable suite of science-policy networks, shared practices, methods, and knowledge integrating science and policy, as well as the main barriers overcome in network development. An important gap that remains for future research is the assessment and evaluation of dialogic science-policy networks' long-term outcomes., Highlights • Current challenges in water access, use, and management constitute wicked problems. • Dialogic science-policy networks can help in addressing wicked water problems. • Eight study cases in the arid Americas exemplify science-policy network approaches. • Dialogic networks foster inclusivity, interaction, involvement, and influence. • Steady commitment and financial support are major challenges to dialogic networks.

Research from multiple domains has provided insights into how neighborhood design can be improved to have a more favorable effect on physical activity, a concept known as walkability. The relevant research findings/hypotheses have been integrated into a Walkability Framework, which organizes the design elements into nine walkability categories. The purpose of this study was to test whether this conceptual framework can be used as a model to measure the interactions between the built environment and physical activity. We explored correlations between the walkability categories and physical activity reported through a survey of residents of Tucson, Arizona (n=486). The results include significant correlations between the walkability categories and physical activity as well as between the walkability categories and the two motivations for walking (recreation and transportation). To our knowledge, this is the first study that reports links between walkability and walking for recreation. Additionally, the use of the Walkability Framework allowed us to identify the walkability categories most strongly correlated with the two motivations for walking. The results of this study support the use of the Walkability Framework as a model to measure the built environment in relation to its ability to promote physical activity.

Greenspace can alleviate many of the negative effects of urbanization and help enhance human well-being yet, in most cities in the world, greenspace is inequitably distributed. In western societies, wealthy white neighborhoods typically have more access to greenspace, constituting an environmental and social justice issue. Although scholars from multiple disciplines and academic domains study questions of justice in greenspace, the scholarship remains fragmented. The purpose of this qualitative review is to explore the diverse disciplinary approaches to justice in urban greenspace to identify patterns and trends in how justice is conceptualized and realized. We analyze a set of case studies across multiple disciplines using a sample of 21 peer-reviewed articles following the framework set out by Bulkeley and colleagues that conceptualizes justice according to recognition, distribution, procedures, rights, and responsibilities. Our results suggest that the various solutions proposed in the diverse streams of scholarship often call for solutions that transcend individual disciplinary boundaries. This finding supports the need for collaborative and cross-disciplinary work to effectively address injustice in urban greenspace. In an effort to integrate findings, we identify five main objectives that need to be addressed by scholars, built environment practitioners, and policymakers, which include: (1) appropriate funding mechanisms for long-term maintenance; (2) recognition of safety concerns; (3) connectivity of greenspace; (4) multifunctionality in greenspace design; and (5) community engagement.

The United States Department of Defense (DoD) recognizes growing climate risks across its responsibilities as land manager, operator of hundreds of installations, and in its core mission to protect national security. However, DoD climate risk reduction is complicated by frequent leadership turnover among base commanders, which encourages focus on near-term challenges, and changing US government priorities that downplay climate risk. We used risk-based deliberation, through workshops, with climate scenario-based fire and flood impact modeling to evaluate risk and adaptation opportunities at bases in the southwestern United States. We found that success in working with Defense installations hinges on linking risks of increasing climate-related impacts to DoD’s ability to achieve its mission objectives at installations. Workshop participants offered insights into barriers to adaptation, including access to decision-makers in a hierarchical organization, leadership focus on near-term challenges, insufficient training or capacity to integrate climate information into short and long-term decisions, and rapid turnover in leadership. We also found opportunities for mainstreaming climate risk management into DoD activities, including emphasizing risks to DoD’s mission, opportunities to form symbiotic partnerships with external partners, and the potential for standardized procedures for considering physical climate risks that could be integrated across the DoD to achieve longer-term solutions to climate change challenges.

In the western US–Mexico border region, both countries’ authorities look to desalination as a means to meet increased demands for dwindling supplies. In addition to several existing or planned desalination plants, plans exist to develop projects along Mexico’s coasts to convert seawater into freshwater primarily for conveyance and consumption in the United States. Even though desalination systems have the potential to increase water supply in the region, there are associated consequences, costs and constraints. To understand the impacts of such binational desalination systems, this paper assesses, through a water-security framework, the case of a proposed desalination plant on the Upper Gulf of California. The analysis suggests that for binational desalination systems, there are several key areas of impact against which the benefits of increased water supply must be weighed.

© 2018, The Author(s). After briefly reviewing key resilience engineering perspectives and summarising some green infrastructure (GI) tools, we present the contributions that GI can make to enhancing urban resilience and maintaining critical system functionality across complex integrated social–ecological and technical systems. We then examine five key challenges for the effective implementation of GI that include (1) standards; (2) regulation; (3) socio-economic factors; (4) financeability; and (5) innovation. We highlight ways in which these challenges are being dealt with around the world, particularly through the use of approaches that are both context appropriate and socially inclusive. Although progress surmounting these challenges has been made, more needs to be done to ensure that GI approaches are inclusive and appropriate and feature equally alongside more traditional ‘grey’ infrastructure in the future of urban resilience planning. This research was undertaken for the Resilience Shift initiative to shift the approach to resilience in practice for critical infrastructure sectors. The programme aims to help practitioners involved in critical infrastructure to make decisions differently, contributing to a safer and better world.

© 2017 Elsevier B.V. Globally, groundwater is by far the largest store of liquid freshwater, making it a key component of a secure water supply. However, over the past few decades the amount of usable groundwater available around the world has rapidly decreased. This depletion is caused primarily by mismanagement (e.g., overpumping, contamination, and under-regulation), but also by reduced natural recharge due to climate change and urbanization. Management of groundwater resources is particularly challenging for the nearly 600 aquifers that are transboundary, meaning that they extend across international political borders. To understand how governance mechanisms can reduce water insecurity in transboundary groundwater contexts, we review key literature from what we view as the most relevant fields: groundwater management, water security, international water law and international water governance. We then formulate a set of recommendations for improved groundwater governance that can address the specific physical nature of groundwater systems, enhance water security, and apply to transboundary groundwater settings. We argue that groundwater governance in transboundary contexts requires processes that (1) enhance context-specific and flexible international mechanisms; (2) address the perpetual need for groundwater data and information; (3) prioritize the precautionary principle and pollution prevention, in particular; (4) where appropriate, integrate governance of surface and subsurface water and land; and (5) expand institutional capacity, especially of binational or multinational actors.

Neighborhood design affects lifestyle physical activity, and ultimately human wellbeing. There are, however, a limited number of studies that examine neighborhood design types. In this research, we examine four types of neighborhood designs: traditional development, suburban development, enclosed community, and cluster housing development, and assess their level of walkability and their effects on physical activity and wellbeing. We examine significant associations through a questionnaire (n = 486) distributed in Tucson, Arizona using the Walkability Model. Among the tested neighborhood design types, traditional development showed significant associations and the highest value for walkability, as well as for each of the two types of walking (recreation and transportation) representing physical activity. Suburban development showed significant associations and the highest mean values for mental health and wellbeing. Cluster housing showed significant associations and the highest mean value for social interactions with neighbors and for perceived safety from crime. Enclosed community did not obtain the highest means for any wellbeing benefit. The Walkability Model proved useful in identifying the walkability categories associated with physical activity and perceived crime. For example, the experience category was strongly and inversely associated with perceived crime. This study provides empirical evidence of the importance of including vegetation, particularly trees, throughout neighborhoods in order to increase physical activity and wellbeing. Likewise, the results suggest that regular maintenance is an important strategy to improve mental health and overall wellbeing in cities.

The use of greenspace has been linked to multiple wellbeing benefits, however there are many factors that influence whether or not residents visit greenspace. In this study, we explore the factors that influence the frequency of greenspace visitation, with a focus on perceptions of walkability, travel mode, and proximity to greenspace. We use a questionnaire to capture perceptions and behaviors of residents (N = 309) and greenspace users (N = 103) in Tucson, Arizona. We estimated binary logistic regression models to identify predictors of daily, weekly, monthly, and yearly visits to greenspace. Results suggest that perceptions of walkability, along with mode of travel, and proximity to greenspace are associated with the frequency of use of greenspace. Walkability elements that were found to influence the probability of greenspace visitation include perceptions of traffic safety (pedestrian and biking infrastructure), surveillance (the extent to which people inside buildings can see pedestrians on the street), and community (spaces that allow social interaction). This study provides empirical evidence to support policies that will improve walkability in neighborhoods so that public health goals of increasing physical activity and wellbeing are achieved.

Conventional water governance that centralizes decision-making and focuses on increasing supply has sometimes led to ecological degradation and inequitable outcomes. As a corrective, Integrated Water Resources Management (IWRM) incorporates sustainability principles that integrate social, ecological, and infrastructural systems. However, this governance mode still does not address complex issues for an uncertain future, and fails to offer a clear goal. Adaptive management, another approach, relies on public participation and active knowledge exchange between scientists and policy-makers; it also incorporates uncertainty into decision-making. The concept of water security emerged subsequently to address the lack of a clear goal for water management. In this paper, we set into context the terms ?adaptive management? and ?water security? and review their evolution and their critiques. Both concepts require measurement and monitoring of outcomes in order to determine progress toward established goals so as to guide decision-making. We discuss the challenges and different ways of measuring water security and offer a representative list of potential indicators. The essay provides some examples of adaptive-management studies across the world and discusses adaptive management as it relates to the UN Sustainable Development Goals. Our concluding remarks reflect on present challenges, practical limitations, and promising ideas for a future type of water governance that is participatory, equitable, and adaptive.

The crucial role of groundwater and the centrality of water governance in accommodating growing water demands sustainably are becoming well recognized. We review 10 case studies of groundwater governance—representing diverse global regions and local contexts—from the perspective of four well-established elements: (1) institutional setting; (2) availability and access to information and science; (3) robustness of civil society; and (4) economic and regulatory frameworks. For institutional setting, we find that governing is often a thankless task that paradoxically requires popularity; legislation does not always translate to implementation; conflict resolution is central to governance; and funding is critical for governance. In terms of information access, we see: a need for research for natural systems, social systems, and institutions; trust as an essential element in research; and that urbanized landscapes are critical components of groundwater governance. Looking at civil society robustness, we observe that equity is an essential element for governance; community-based governance requires intention; and leaders can play a powerful role in uniting stakeholders. As for frameworks, the cases suggest that economic incentives sometimes yield unintended results; “indirect” management should be used cautiously; and economic incentives’ effectiveness depends on the system employed. Collectively, the lessons speak to the need for shared governance capacities on the part of governments at multiple levels and civil society actors.

Prevailing city design in many countries has created sedentary societies that depend on automobile use. Consequently, architects, urban designers, and land planners have developed new urban design theories, which have been incorporated into the Leadership in Energy and Environmental Design for Neighborhood Development (LEED-ND) certification system. The LEED-ND includes design elements that improve human well-being by facilitating walking and biking, a concept known as walkability. Despite these positive developments, relevant research findings from other fields of study have not been fully integrated into the LEED-ND. According to Zuniga-Teran (2015), relevant walkability research findings from multiple disciplines were organized into a walkability framework (WF) that organizes design elements related to physical activity into nine categories, namely, connectivity, land use, density, traffic safety, surveillance, parking, experience, greenspace, and community. In this study, we analyze walkability in the LEED-ND through the lens of the nine WF categories. Through quantitative and qualitative analyses, we identify gaps and strengths in the LEED-ND and propose potential enhancements to this certification system that reflects what is known about enhancing walkability more comprehensively through neighborhood design analysis. This work seeks to facilitate the translation of research into practice, which can ultimately lead to more active and healthier societies.
