Geographies Of Transition—From Topical Concerns To Theoretical Engagement: A Commentary On The Transitions Research Agenda, Christian Binz, Lars Coenen, James T. Murphy, Bernhard Truffer
Geographies Of Transition—From Topical Concerns To Theoretical Engagement: A Commentary On The Transitions Research Agenda, Christian Binz, Lars Coenen, James T. Murphy, Bernhard Truffer
Geography
This viewpoint takes stock with the ‘geography of sustainability transitions’ (GOST) as it is presented in the transitions research agenda. GOST has been a relatively recent addition to transition theorizing, addressing the need for greater sensitivity and attention to the scales, spatialities, and context-specific factors that shape transitions. In our view, the agenda represents a rather narrow perspective on GOST, which is geared to two empirical themes, namely urban transitions and transitions in developing countries. While these are relevant and topical issues, the section lacks sufficient acknowledgement of the increasing engagement of geographers with transitions studies and the theoretical approaches …

Effects Of Category Aggregation On Land Change Simulation Based On Corine Land Cover Data, Orsolya Gyöngyi Varga, Robert Gilmore Pontius, Zsuzsanna Szabó, Szilárd Szabó
Effects Of Category Aggregation On Land Change Simulation Based On Corine Land Cover Data, Orsolya Gyöngyi Varga, Robert Gilmore Pontius, Zsuzsanna Szabó, Szilárd Szabó
Geography
Several factors influence the performance of land change simulation models. One potentially important factor is land category aggregation, which reduces the number of categories while having the potential to reduce also the size of apparent land change in the data. Our article compares how four methods to aggregate Corine Land Cover categories influence the size of land changes in various spatial extents and consequently influence the performance of 114 Cellular Automata-Markov simulation model runs. We calculated the reference change during the calibration interval, the reference change during the validation interval and the simulation change during the validation interval, along with …

Enhanced Intensity Analysis To Quantify Categorical Change And To Identify Suspicious Land Transitions: A Case Study Of Nanchang, China, Zheyu Xie, Robert Gilmore Pontius, Jinliang Huang, Vilas Nitivattananon
Geography
Conventional methods to analyze a transition matrix do not offer in-depth signals concerning land changes. The land change community needs an effective approach to visualize both the size and intensity of land transitions while considering possible map errors. We propose a framework that integrates error analysis, intensity analysis, and difference components, and then uses the framework to analyze land change in Nanchang, the capital city of Jiangxi province, China. We used remotely sensed data for six categories at four time points: 1989, 2000, 2008, and 2016. We had a confusion matrix for only 2016, which estimated that the map of …

A Green Transition In South Africa? Sociotechnical Experimentation In The Atlantis Special Economic Zone, Richard Grant, Pádraig Carmody, James T. Murphy
Geography
South Africa faces interconnected challenges of developing and diversifying its economy and adapting to and mitigating the impacts of climate change. A green policy tilt is ascendant in the country, manifest in a cascading array of policies and special initiatives. Utilising concepts from the multi-level perspective on socio-technical transitions, we assess Africa's first designated Green Special Economic Zone (SEZ), Atlantis SEZ (ASEZ) in the Western Cape, a niche innovation aimed at transforming the Province's industrial base. This initiative is very ambitious in four respects: (1) it links green SEZ development in a deprived metropolitan area to the broader regional economy; …

Framing The Search For A Theory Of Land Use, B. L. Turner, Patrick Meyfroidt, Tobias Kuemmerle, Daniel Müller, Rinku Roy Chowdhury
Geography
Land system science and affiliated research linked to sustainability require improved understanding and theorization of land and its change as a social-ecological system (SES). The absence of a general land-use theory, anchored in the social subsystem but with explicit links to the environmental subsystem, hampers this effort. Drawing on land-use explanations, meta-analyses, and associated frameworks, we advance a broad framework structure of eight elements–aggregations of explanatory variables–with links to the biophysical subsystem, for systematic comparisons of extant explanations. Tests and models can be employed to identify which set of variables and their configurations provide robust explanations of across land uses, …

Forests have re-taken centre stage in global conversations about sustainability, climate and biodiversity. Here, we use a horizon scanning approach to identify five large-scale trends that are likely to have substantial medium- and long-term effects on forests and forest livelihoods: forest megadisturbances; changing rural demographics; the rise of the middle-class in low- and middle-income countries; increased availability, access and use of digital technologies; and large-scale infrastructure development. These trends represent human and environmental processes that are exceptionally large in geographical extent and magnitude, and difficult to reverse. They are creating new agricultural and urban frontiers, changing existing rural landscapes and …

Geography
Remote sensing, or Earth Observation (EO), is increasingly used to understand Earth system dynamics and create continuous and categorical maps of biophysical properties and land cover, especially based on recent advances in machine learning (ML). ML models typically require large, spatially explicit training datasets to make accurate predictions. Training data (TD) are typically generated by digitizing polygons on high spatial-resolution imagery, by collecting in situ data, or by using pre-existing datasets. TD are often assumed to accurately represent the truth, but in practice almost always have error, stemming from (1) sample design, and (2) sample collection errors. The latter is …
Change Points Detected In Decadal And Seasonal Trends Of Outlet Glacier Terminus Positions Across West Greenland, Ashley V. York, Karen E. Frey, Sadegh Jamali, Sarah B. Das
Change Points Detected In Decadal And Seasonal Trends Of Outlet Glacier Terminus Positions Across West Greenland, Ashley V. York, Karen E. Frey, Sadegh Jamali, Sarah B. Das
Geography
We investigated the change in terminus position between 1985 and 2015 of 17 marine-terminating glaciers that drain into Disko and Uummannaq Bays, West Greenland, by manually digitizing over 5000 individual frontal positions from over 1200 Landsat images. We find that 15 of 17 glacier termini retreated over the study period, with ~80% of this retreat occurring since 2000. Increased frequency of Landsat observations since 2000 allowed for further investigation of the seasonal variability in terminus position. We identified 10 actively retreating glaciers based on a significant positive relationship between glaciers with cumulative retreat >300 m since 2000 and their average …

Integrated Approaches To Understanding And Reducing Drought Impact On Food Security Across Scales, Xiaogang He, Lyndon Estes, Megan Konar, Di Tian, Daniela Anghileri, Kathy Baylis, Tom P. Evans, Justin Sheffield
Geography
Understanding the cross-scale linkages between drought and food security is vital to developing tools to reduce drought impacts and support decision making. This study reviews how drought hazards transfer to food insecurity through changes in physical processes and socio-environmental systems across a wide range of spatial and temporal scales. We propose a multi-scale, integrated framework leveraging modeling advances (e.g. drought and crop monitoring, water-food-energy nexus, decision making) and increased data availability (e.g. satellite remote sensing, food trade) through the lens of the coupled human–natural system to support multidisciplinary approaches and avoid potential policy spillover effects. We discuss current scale-dependent challenges …

Giroux, Inna Kouper, Lyndon Estes, Jacob Schumacher, Kurt Waldman, Joel T. Greenshields, Stephanie L. Dickinson, Kelly K. Caylor, Tom P. Evans
Geography
Collecting high-frequency social-environmental data about farming practices in sub-Saharan Africa can provide new insight into environmental changes that farmers face and how they respond within smallholder agro-ecosystems. Traditional data collection methods such as agricultural censuses are costly and not useful for understanding intra-annual and real-time decisions. Short-message service (SMS) has the potential to transform the nature of data collection in coupled social-ecological systems. We present a system for collecting, managing, and synthesizing weekly data from farmers, including data infrastructure for management of big and heterogeneous datasets; probabilistic data quality assessment tools; and visualization and analysis tools such as mapping and …
Food Deserts Debunked And Decentered: From Deficit To Relational Mapping For Food Justice In Worcester, Ma, Brenna Robeson
Food Deserts Debunked And Decentered: From Deficit To Relational Mapping For Food Justice In Worcester, Ma, Brenna Robeson
Sustainability and Social Justice
The mapping of food deserts has become a standardized component of food and health policy work concerned with expanding food access. These maps often follow a similar format of spatially identifying where grocery stores are absent in communities, thus suggesting a straightforward problem diagnosis and intervention blueprint. This paper questions the over-emphasis among many food and health policy practitioners on these technically engineered policy stories, specifically for their obstruction of histories of white supremacy and capitalism within the US food system and urban landscapes. A mixed-methods approach is applied to a case study of Worcester, MA which appropriates GIS to …

Science should provide solutions for societal transformations toward sustainability in the face of global environmental change. Land system science, as a systemic science focused on complex socio-ecological interactions around land use and associated trade-offs and synergies, is well placed to contribute to this agenda. This goal requires a stronger engagement with the normative implications of scientific practice, research topics, questions and results. We identify concerns as well as three concrete steps for land system science to more deeply contribute in normative issues. In particular, we encourage land system scientists to discuss explicitly the normative questions, values, perspectives and assumptions already …
Assessing The Impacts Of Gold Mining Deforestation On The Giant Otter (Pteronura Brasiliensis) In Madre De Dios, Peru, Erica Carcelen
Assessing The Impacts Of Gold Mining Deforestation On The Giant Otter (Pteronura Brasiliensis) In Madre De Dios, Peru, Erica Carcelen
Sustainability and Social Justice
Gold mining activity is highly prevalent in the Madre de Dios region, Peru. This activity poses large environmental impacts including deforestation, sedimentation of rivers, and pollution from mercury used during extraction. Mining activity is a major threat to the endangered giant otter as it destroys its preferred riverine habitat. Moreover, mercury used during gold extraction bio-accumulates in fish, which constitutes the entirety of their diet. In order to conserve the giant otter, it is necessary to identify conservation priority areas. In a reactive conservation planning approach, the objective of this work was to prioritize areas suitable as giant otter habitat …

Analyzing Trends And Patterns In Adverse Birth Outcomes In Massachusetts From 2000-2014, Madeleine Haynes
Sustainability and Social Justice
This study explores spatio-temporal trends and patterns in adverse birth outcomes (ABO) in the state of Massachusetts from 2000-2014. ABO include low birth weight (< 2500 g) and preterm deliveries (gestational age < 37 weeks). This research evaluates if there are areas in Massachusetts that have experienced statistically significant increases or decreases in ABO throughout the study period. Birth data was obtained from the Massachusetts Department of Public Health and only singleton, live births were included for the analysis. The data were aggregated to census tracts, and the total number of births and the number of ABOs were calculated for each census tract for each year. In total, 1478 census tracts were included in this analysis. Births to non-Hispanic black mothers and births to non-Hispanic white mothers were separated to evaluate if trends in ABO are similar regardless of race as previous literature has identified a much higher rate of ABO in births to non-Hispanic black women. Trends and patterns of ABO were evaluated using the Space Time Cube and the Mann-Kendall statistic and a multivariate regression was conducted to identify potential correlations between socioeconomic factors and prevalence of ABO. Results of this study can be used to identify areas that are experiencing an increase in ABO to potentially allow for more effective, targeted intervention methods.

An Evaluation Of Sentinel-1 And Sentinel-2 For Land Cover Classification, Aaron Meneghini
Sustainability and Social Justice
This study evaluates Sentinel-1 and Sentinel-2 remotely sensed images for tropical land cover classification. The dual polarized Sentinel-1 VV and VH backscatter images and four 10-meter multispectral bands of Sentinel-2 were used to create six land cover classification images across two study areas along the border of the Bolivian Pando Department and the Brazilian state of Acre. Results indicate that Sentinel-2 multispectral bands possess a higher overall performance in delineating land cover types than the Sentinel-1 backscatter bands. Sentinel-1 backscatter bands delineated land cover types based on their surficial properties but did not facilitate the separation of similarly textured classes. …

Given the varying manifestations of climate change over time and the influence of climate perceptions on adaptation, it is important to understand whether farmer perceptions match patterns of environmental change from observational data. We use a combination of social and environmental data to understand farmer perceptions related to rainy season onset. Household surveys were conducted with 1171 farmers across Zambia at the end of the 2015/16 growing season eliciting their perceptions of historic changes in rainy season onset and their heuristics about when rain onset occurs. We compare farmers' perceptions with satellite-gauge-derived rainfall data from the Climate Hazards Group Infrared …
Sacrifices For Development Or Thirst For Capital Accumulation? Case Study On The “El Diquís Hydroelectric Dam” In Costa Rica., Marco Mora
Sustainability and Social Justice
Costa Rica’s state-led model of energy generation based on large-scale investments in hydropower has given the country autonomy in generating its own energy as well as sovereignty over its natural resources. Successive governments have used nationalist and ecological discourses to support the continued expansion of hydropower as the path to economic development. In more recent decades however, a number of factors have been eroding the dominance of the state-led hydropower development model. Some of those elements are the national and international pressures to liberalize and privatize the energy sector, an increasing body of scientific evidence indicating that large-scale hydropower in …

Probabilistic Global Maps Of Crop-Specific Areas From 1961 To 2014, Nicole D. Jackson, Megan Konar, Peter Debaere, Lyndon Estes
Geography
Agriculture has substantial socioeconomic and environmental impacts that vary between crops. However, information on how the spatial distribution of specific crops has changed over time across the globe is relatively sparse. We introduce the Probabilistic Cropland Allocation Model (PCAM), a novel algorithm to estimate where specific crops have likely been grown over time. Specifically, PCAM downscales annual and national-scale data on the crop-specific area harvested of 17 major crops to a global 0.5-degree grid from 1961 to 2014. To do this, pixels are assigned into probability clusters based upon crop-specific pixel suitability (based on mean climate and soil characteristics) and …

Subglacial Roughness Of The Greenland Ice Sheet: Relationship With Contemporary Ice Velocity And Geology, Michael A. Cooper, Thomas M. Jordan, Dustin M. Schroeder, Martin J. Siegert, Christopher N. Williams, Jonathan L. Bamber
Geography
The subglacial environment of the Greenland Ice Sheet (GrIS) is poorly constrained both in its bulk properties, for example geology, the presence of sediment, and the presence of water, and interfacial conditions, such as roughness and bed rheology. There is, therefore, limited understanding of how spatially heterogeneous subglacial properties relate to ice-sheet motion. Here, via analysis of 2 decades of radio-echo sounding data, we present a new systematic analysis of subglacial roughness beneath the GrIS. We use two independent methods to quantify subglacial roughness: first, the variability in along-track topography - enabling an assessment of roughness anisotropy from pairs of …

Unbundling Property In Boston’S Urban Food Commons, Oona Morrow, Deborah Martin
Geography
Households and community organizations are involved in the creation, use, care, and management of urban spaces, including through food practices such as planting, foraging, harvesting, weeding and pruning at the ambiguous edges of public and private property. Drawing on case studies in Boston, Massachusetts, we examine how commons are articulated through these practices, particularly in relation to multiple dimensions of property rights. Specifically, we ask how food practices can open urban spaces to negotiations around access, responsibility, care, and ownership, especially when (property) ownership is not an end-goal, but a circumstance shaping other practices. Using interviews and participant observation of …

Residential land is expanding in the United States, and lawn now covers more area than the country’s leading irrigated crop by area. Given that lawns are widespread across diverse climatic regions and there is rising concern about the environmental impacts associated with their management, there is a clear need to understand the geographic variation, drivers, and outcomes of common yard care practices. We hypothesized that 1) income, age, and the number of neighbors known by name will be positively associated with the odds of having irrigated, fertilized, or applied pesticides in the last year, 2) irrigation, fertilization, and pesticide application …

Changes in land systems generate many sustainability challenges. Identifying more sustainable land-use alternatives requires solid theoretical foundations on the causes of land-use/cover changes. Land system science is a maturing field that has produced a wealth of methodological innovations and empirical observations on land-cover and land-use change, from patterns and processes to causes. We take stock of this knowledge by reviewing and synthesizing the theories that explain the causal mechanisms of land-use change, including systemic linkages between distant land-use changes, with a focus on agriculture and forestry processes. We first review theories explaining changes in land-use extent, such as agricultural expansion, …

A New Mass Incarceration: Community Corrections, Carceral Geography, And Spatial Power, Iolanthe Brooks
Scholarly Undergraduate Research Journal at Clark (SURJ)
In the age of Michelle Alexander’s The New Jim Crow (2010), promises to depopulate overcrowded American prisons, and a mainstream acknowledgement of mass incarceration, the American criminal justice system is anything but inert. Instead, modalities of punishment are shifting, particularly towards community-located corrections involving GPS surveillance. This paper seeks to examine this evolution of the carceral state through the marriage of two theoretical lenses: carceral geography and Foucauldian spatial power analysis. Carceral geography offers a theory of the embodied nuance of movement. Its work revolves around the three mobilities of the carceral system: movement to/from, within, and between prisons. This …
