Theorising Democratic Space with and beyond Henri Lefebvre
Purcell, Mark. (2022). Theorising Democratic Space with and beyond Henri Lefebvre. Urban Studies, 59(15), 3041-3059.
Abstract
The purpose of this article is to theorise space in a way that resonates with democracy. It develops a radical understanding of democracy, as an affirmative project undertaken by people to directly manage their affairs themselves. To theorise space, the article takes up Henri Lefebvre's concept of 'differential space', which it conceives as an autonomous force that produces itself through the operation of desire. This self-production, Lefebvre argues, takes place in and through everyday acts of survival of those who inhabit space. The article then situates this abstract discussion of space, again following Lefebvre, in the context of ongoing worldwide urbanisation. The urban, Lefebvre argues, has agglomerated not only capitalist productive power but also the differences that exist outside of capitalist logic, and so it is where we should be looking for revolutionary difference in the world today. Taking all these insights together, we can see the project of democracy as an affirmative project undertaken by people to directly manage the production of urban space themselves. Lastly, the article argues that the project of democracy must extend beyond Lefebvre's thought. It thinks through one example, which is the question of the 'we' of democracy. It argues that to properly understand the question of difference in democratic community, we are very well served in turning to the work of Judith Butler.

(2022). What Next? Expanding Our View of City Planning and Global Health, and Implementing and Monitoring Evidence-informed Policy. Lancet Global Health, 10(6), E919-E926.
Abstract
This Series on urban design, transport, and health aimed to facilitate development of a global system of health-related policy and spatial indicators to assess achievements and deficiencies in urban and transport policies and features. This final paper in the Series summarises key findings, considers what to do next, and outlines urgent key actions. Our study of 25 cities in 19 countries found that, despite many well intentioned policies, few cities had measurable standards and policy targets to achieve healthy and sustainable cities. Available standards and targets were often insufficient to promote health and wellbeing, and health-supportive urban design and transport features were often inadequate or inequitably distributed. City planning decisions affect human and planetary health and amplify city vulnerabilities, as the COVID-19 pandemic has highlighted. Hence, we offer an expanded framework of pathways through which city planning affects health, incorporating 11 integrated urban system policies and 11 integrated urban and transport interventions addressing current and emerging issues. Our call to action recommends widespread uptake and further development of our methods and open-source tools to create upstream policy and spatial indicators to benchmark and track progress; unmask spatial inequities; inform interventions and investments; and accelerate transitions to net zero, healthy, and sustainable cities.

Dylan Stevenson’s (Prairie Band Potawatomi descent) research examines how culture informs planning strategies and influences land relationships. More specifically, he investigates how tribal epistemologies structure notions of Indigenous futurities by centering Indigenous cultural values at the forefront of environmental stewardship and cultural preservation. He is currently working on a project researching how governments (Federal, State, and Tribal) embed cultural values in Water Resources Planning strategies, drawing from ethnographic research he conducted in the joint territory of the United Keetoowah Band of Cherokee Indians and Cherokee Nation in Oklahoma. His other research interests include ecological restoration, intangible cultural heritage, and food systems planning. Previously, Dylan has worked for public and quasi-public entities dealing with the implementation and compliance of local, state, and federal legislation in California and has forthcoming work analyzing Diversity, Equity, and Inclusion (DEI) initiatives in planning programs.

Effects of Mid-Twenty-first Century Climate and Land Cover Change on the Hydrology Of the Puget Sound Basin, Washington
Cuo, Lan; Beyene, Tazebe K.; Voisin, Nathalie; Su, Fengge; Lettenmaier, Dennis P.; Alberti, Marina; Richey, Jeffrey E. (2011). Effects of Mid-Twenty-first Century Climate and Land Cover Change on the Hydrology Of the Puget Sound Basin, Washington. Hydrological Processes, 25(11), 1729 – 1753.
Abstract
The distributed hydrology-soil-vegetation model (DHSVM) was used to study the potential impacts of projected future land cover and climate change on the hydrology of the Puget Sound basin, Washington, in the mid-twenty-first century. A 60-year climate model output, archived for the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4), was statistically downscaled and used as input to DHSVM. From the DHSVM output, we extracted multi-decadal averages of seasonal streamflow, annual maximum flow, snow water equivalent (SWE), and evapotranspiration centred around 2030 and 2050. Future land cover was represented by a 2027 projection, which was extended to 2050, and DHSVM was run (with current climate) for these future land cover projections. In general, the climate change signal alone on sub-basin streamflow was evidenced primarily through changes in the timing of winter and spring runoff, and slight increases in the annual runoff. Runoff changes in the uplands were attributable both to climate (increased winter precipitation, less snow) and land cover change (mostly reduced vegetation maturity). The most climatically sensitive parts of the uplands were in areas where the current winter precipitation is in the rain-snow transition zone. Changes in land cover were generally more important than climate change in the lowlands, where a substantial change to more urbanized land use and increased runoff was predicted. Both the annual total and seasonal distribution of freshwater flux to Puget Sound are more sensitive to climate change impacts than to land cover change, primarily because most of the runoff originates in the uplands. Both climate and land cover change slightly increase the annual freshwater flux to Puget Sound. Changes in the seasonal distribution of freshwater flux are mostly related to climate change, and consist of double-digit increases in winter flows and decreases in summer and fall flows.

Walking Objectively Measured: Classifying Accelerometer Data with GPS and Travel Diaries
Kang, Bumjoon; Moudon, Anne V.; Hurvitz, Philip M.; Reichley, Lucas; Saelens, Brian E. (2013). Walking Objectively Measured: Classifying Accelerometer Data with GPS and Travel Diaries. Medicine & Science In Sports & Exercise, 45(7), 1419 – 1428.
Abstract
Purpose: This study developed and tested an algorithm to classify accelerometer data as walking or nonwalking using either GPS or travel diary data within a large sample of adults under free-living conditions. Methods: Participants wore an accelerometer and a GPS unit and concurrently completed a travel diary for seven consecutive days. Physical activity (PA) bouts were identified using accelerometry count sequences. PA bouts were then classified as walking or nonwalking based on a decision-tree algorithm consisting of seven classification scenarios. Algorithm reliability was examined relative to two independent analysts' classification of a 100-bout verification sample. The algorithm was then applied to the entire set of PA bouts. Results: The 706 participants' (mean age = 51 yr, 62% female, 80% non-Hispanic white, 70% college graduate or higher) yielded 4702 person-days of data and had a total of 13,971 PA bouts. The algorithm showed a mean agreement of 95% with the independent analysts. It classified PA into 8170 walking bouts (58.5 %) and 5337 nonwalking bouts (38.2%); 464 bouts (3.3%) were not classified for lack of GPS and diary data. Nearly 70% of the walking bouts and 68% of the nonwalking bouts were classified using only the objective accelerometer and GPS data. Travel diary data helped classify 30% of all bouts with no GPS data. The mean + SD duration of PA bouts classified as walking was 15.2 + 12.9 min. On average, participants had 1.7 walking bouts and 25.4 total walking minutes per day. Conclusions: GPS and travel diary information can be helpful in classifying most accelerometer-derived PA bouts into walking or nonwalking behavior.

The Influence of Street Environments on Fuel Efficiency: Insights from Naturalistic Driving
Wang, X.; Liu, C.; Kostyniuk, L.; Shen, Q.; Bao, S. (2014). The Influence of Street Environments on Fuel Efficiency: Insights from Naturalistic Driving. International Journal Of Environmental Science And Technology, 11(8), 2291 – 2306.
Abstract
Fuel consumption and greenhouse gas emissions in the transportation sector are a result of a three-legged stool: fuel types, vehicle fuel efficiency, and vehicle miles travelled (VMT). While there is a substantial body of literature that examines the connection between the built environment and total VMT, few studies have focused on the impacts of the street environment on fuel consumption rate. Our research applied structural equation modeling to examine how driving behaviors and fuel efficiency respond to different street environments. We used a rich naturalistic driving dataset that recorded detailed driving patterns of 108 drivers randomly selected from the Southeast Michigan region. The results show that, some features of compact streets such as lower speed limit, higher intersection density, and higher employment density are associated with lower driving speed, more speed changes, and lower fuel efficiency; however, other features such as higher population density and higher density of pedestrian-scale retails improve fuel efficiency. The aim of our study is to gain further understanding of energy and environmental outcomes of the urban areas and the roadway infrastructure we plan, design, and build and to better inform policy decisions concerned with sustainable transportation.

Rediscovering Japanese Urban Space in a World Context
Oshima, Ken Tadashi. (2016). Rediscovering Japanese Urban Space in a World Context. Journal Of Urban History, 42(3), 623 – 633.
Abstract
Counter to the rise of the modern metropolis in Japan in the era of high-speed growth following World War II, a movement to embrace elements of traditional townscapes that had been lost as rational urban planning took hold from the mid-1950s to the mid-1970s. During this period, the realities of large-scale urban development and increasing urban problems would eventually expose the limitations of functional planning and the need to preserve traditional structures and townscapes. While architects like Bruno Taut had praised the virtues of the farmhouse villages at Shirakawago in the 1930s and Yoshida Tetsur presented traditional Japanese architecture to an international audience as contemporary design before World War II, among others, the discourse subsequently shifted from Japanese objects and structures to urban space in the postwar period. This discourse on Japanese urban space would lead to the publication of Nihon no toshi kukan (Japanese Urban Space) in 1963 (1968 as a book) that presented the work of the Toshi dezain kenkyutai (Urban Design Research Group) including Isozaki Arata (1931-) and architectural historian It Teiji (1922-2010). This article analyzes the origins and implications of this work through a plethora of subsequent design surveys throughout Japan and other trajectories of research and design of Japanese urban space from the 1960s to the present.

Planning in the Spirit of Deleuze and Guattari? Considering Community-Based Food Projects in the United States and Mexico
Purcell, Mark; Born, Branden. (2017). Planning in the Spirit of Deleuze and Guattari? Considering Community-Based Food Projects in the United States and Mexico. Urban Geography, 38(4), 521 – 536.
Abstract
In this article we argue that planning theory and practice should engage more with the normative political vision of Gilles Deleuze and Felix Guattari. They reject the transcendent authority of the State and arguably by extension, planning. As planners we should be concerned: need we reconceptualize, or abandon the planning project? We outline their vision, highlighting key concepts including lines of flight, revolution, the new land, and immanent organization, and use two cases from the United States and Mexico, the Food Commons and Center for Integral Farmer Development in the Mixteca, to show that planning in accordance with Deleuze and Guattari may indeed be possible. We end with questions: is what we describe planning? And what is planning - or what should it be?
