Broadening Diversity, Equity, Accessibility, And Inclusion In The Process And Development Of Climate Assessments, Eric K. Chu, Gillian Bowser, Abby Frazier, Alyssa Quintyne, Linda Shi, Pamela Mcelwee

Geography

Comprehensive assessments of scientific knowledge are essential to inform efforts to mitigate greenhouse gas emissions and adapt to climate change impacts. The Fifth National Climate Assessment (NCA5), released in late 2023, adopted clear diversity, equity, accessibility, and inclusion (DEAI) goals and trainings, which helped diversify expert participation, broaden the types of knowledge included, and widen public engagement. This Letter, written by NCA5 authors, reflects on the impacts and limitations of these efforts and suggests specific actions to further promote collaboration, honor and recognize the knowledge of frontline communities, and guide more just and holistic climate assessments.

Geography

Drought is a period of abnormally dry weather that leads to hydrological imbalance. Drought assessments determine the characteristics, severity, and impacts of a drought. Climate change adds conceptual and quantitative challenges to traditional drought assessments. This paper highlights the challenges of assessing drought in a climate made non-stationary by human activities or natural variability. To address these challenges, we then identify 10 key research priorities for advancing drought science and improving assessments in a changing climate. The priorities focus on improving drought indicators to account for non-stationarity, evaluating drought impacts and their trends, addressing regional differences in non-stationarity, determining the …

Forest Carbon Modeling Improved Through Hierarchical Assimilation Of Pool-Based Measurements, Yu Zhou, Christopher A. Williams

Geography

Accurate assessment of forest carbon dynamics is a critical element of appraising forest-based Natural Climate Solutions. National forest inventory and analysis (FIA) data provide valuable pool-based estimates of carbon stocks, but have been underutilized to inform carbon cycle modeling for forest carbon dynamics with stand development. This study introduces a hierarchical data assimilation (HDA) framework to optimize modeling parameters by incrementally assimilating measured carbon pool data into the model. We found that most carbon stocks could be reproduced by constrained parameters after each HDA step. Using aboveground live biomass (AGB) alone in HDA was able to reproduce the AGB trajectories …

Geography

Observing the Earth with satellites offers clear advantages when it comes to tracking the health of the planet—consistent measurements that can be translated into environmentally relevant estimates, such as carbon, crop productivity, or land use. The resulting information covers large regions, irrespective of administrative boundaries. These measurements also drastically reduce costs compared with on-the-ground data collection efforts. Earth observation (EO) data thereby efficiently deliver timely insights that can directly inform sustainability debates, including with regard to United Nations (UN) Sustainable Development Goals (SDGs). At the heart of these efforts are open data initiatives linked to the public release of medium- …

Generalization Enhancement Strategies To Enable Cross-Year Cropland Mapping With Convolutional Neural Networks Trained Using Historical Samples, Sam Khallaghi, Rahebeh Abedi, Hanan Ali Abou, Hamed Alemohammad, Mary Dziedzorm Asipunu, Ismail Alatise, Nguyen Ha, Boka Luo, Cat Mai, Lei Song, Amos Olertey Wussah, Sitian Xiong

Geography

Mapping agricultural fields using high-resolution satellite imagery and deep learning (DL) models has advanced significantly, even in regions with small, irregularly shaped fields. However, effective DL models often require large, expensive labeled datasets, which are typically limited to specific years or regions. This restricts the ability to create annual maps needed for agricultural monitoring, as changes in farming practices and environmental conditions cause domain shifts between years and locations. To address this, we focused on improving model generalization without relying on yearly labels through a holistic approach that integrates several techniques, including an area-based loss function, Tversky-focal loss (TFL), data …

Potential 2050 Distributions Of World Terrestrial Ecosystems From Projections Of Changes In World Climate Regions And Global Land Cover, Roger Sayre, Charlie Frye, Sean Breyer, Patrick R. Roehrdanz, Paul R. Elsen, Kevin Butler, Clint Brown, Jill Cress, Deniz Karagulle, Madeline Martin, Florencia Sangermano, Regan L. Smyth, Terry L. Sohl, Nicholas H. Wolff, Dawn J. Wright, Zhouting Wu

Geography

The urgency to address ecosystem loss is paramount, as both land use change and climate change will continue to rapidly alter and degrade natural ecosystems and reduce the many services they provide. To support conservation actions that mitigate impacts from these dual threats, we have developed potential World Terrestrial Ecosystem (WTE) distributions for 2050 following IPCC best practice guidelines. This projection of ecosystem distributions builds on the previously released 2015 WTEs, a snapshot of the distribution and conservation status of 431 terrestrial ecosystem types defined as distinct combinations of 18 global climate regions, 4 global landform classes, and 8 global …

Life Stories Of Garment Workers In India: Toward A Labor-Centric Labor Regimes Framework, Siobhán Mcgrath, Madhumita Dutta

Geography

This article contributes to a recent wave of literature formulating a renewed labor regimes framework as a means to understand the processes, relations, actors, and institutions through which conditions of work are produced under contemporary capitalism. This scholarship (partially) incorporates a feminist lens highlighting the centrality of social reproduction to the construction and persistence of particular labor regimes, and further calls for “labor-centric” analyses to counter a “capital-centric” tendency. We take up this call through analyzing the life stories of three garment workers in India, centering their own perspectives about their labor and motivations for entering and exiting particular labor …

He's A Builder, But Does Trump Have An Urban Agenda?, Mark Davidson

Geography

For 20 years, turbulence has defined American urbanism. In the late noughties, a global financial crisis pushed many US cities to the brink of bankruptcy. Austerity followed, with belt-tightening squeezing city services. Then came Trump, then came COVID. The pandemic would, unpredictably, make US cities cash rich thanks to the Federal government's largesse. And now we await Trump 2.0. For US cities the prospect of radical change seems real. But what type of reform will Trump bring? Herein lies the difficulty. Trump 2.0 is as hard to predict as the first version was. Immigration, tariff reform and government efficiency are …

The Potential For Albedo-Induced Climate Mitigation Using No-Till Management In Midwestern U.S. Croplands, Xian Wang, Mallory Barnes, Landon Yoder, Christopher A. Williams, Jennifer Tank, Todd Royer, Shellye Suttles, Kim Novick

Geography

No-till management is often recognized for its environmental and economic benefits, but its potential to reduce climate warming is still uncertain. Beyond ongoing debate over its effects on soil carbon storage, no-till also leaves plant residue on the surface, which can reflect more sunlight. This increase in surface reflectivity, called albedo, may help mitigate climate change by reducing the energy absorbed by the land. Here, we assessed this climate benefit of no-till across the U.S. Corn Belt using conservation survey records, county-level tillage data, and satellite observations. We found that no-till increased land surface brightness during the dormant season, reducing …

Merging Adoption Of Natural Climate Solutions In Agriculture With Climatic And Non-Climatic Risks Within An (Intra)Gendered Framework, Kwabena Antwi

Student Publications [Scholarly]

The extant research on climate variability shares significant theoretical contributions to vulnerability and risks. However, the literature mostly focuses on technical solutions to climate extremes which undermines efforts to identify and solve the dynamics within gender groups in using agricultural-based natural climate solutions (NCS) to address climatic and non-climatic risks. With this in mind, this study implements both quantitative and qualitative approaches including household surveys, key informant interviews, and focus group discussions to investigate the adoption of NCS within gender groups to address climatic and non-climatic risks in three selected communities (Katanga, Dakio, and Zonno) in the Bolgatanga East District …

Student Publications [Scholarly]

Peru's Southeastern Amazon deforestation trends can be attributed to alluvial gold mining. Illegal mining occurring in forestry concessions, national parks, and the territories of Indigenous People Organizations is of particular concern. We present a methodology to create near real-time alerts of deforestation caused by alluvial gold mining. A time series of Sentinel-1 Synthetic Aperture Radar (SAR) data from February to December 2022 is created in Google Earth Engine (GEE) and assessed using Morton Canty's Omnibus Q-test change detection algorithm. Resulting detections are validated with high-resolution optical imagery from Planet NICFI's monthly basemaps and Planet Scope daily imagery. The alerts identify …

Accounting For Albedo Change To Identify Climate-Positive Tree Cover Restoration, Natalia Hasler, Christopher A. Williams, Vanessa Carrasco Denney, Peter W. Ellis, Surendra Shrestha, Drew E. Terasaki Hart, Nicholas H. Wolff, Samantha Yeo, Thomas W. Crowther, Leland K. Werden, Susan Cook-Patton

Geography

Restoring tree cover changes albedo, which is the fraction of sunlight reflected from the Earth’s surface. In most locations, these changes in albedo offset or even negate the carbon removal benefits with the latter leading to global warming. Previous efforts to quantify the global climate mitigation benefit of restoring tree cover have not accounted robustly for albedo given a lack of spatially explicit data. Here we produce maps that show that carbon-only estimates may be up to 81% too high. While dryland and boreal settings have especially severe albedo offsets, it is possible to find places that provide net-positive climate …

A Call To Strengthen International Collaboration To Assess Climate Change Effects In Polar Regions, Clare B. Gaffey, Narissa Bax, Naomi Krauzig, Kévin Tougeron

Student Publications [Scholarly]

Climate change is exerting complex and transformative effects in the Arctic and Antarctic; regions that are essential to global climate, biodiversity, and sustainable futures. Given the polar regions’ roles in Earth’s system, a robust, coordinated, and innovative strategy to monitor and manage climate change effects is needed. Insufficient baseline data, inconsistent international collaboration, and short-term financing are obstacles to effectively monitor these changes. This hinders our understanding of biodiversity shifts, their implications for food security, and climate change mitigation. Confronting the impacts of climate change will require interdisciplinary collaboration and genuine participation of nations, including Indigenous communities. This sentiment includes …

Analyzing The Losses And Gains Of A Land Category: Insights From The Total Operating Characteristic, Thomas Mumuni Bilintoh, Robert Gilmore Pontius, Zhen Liu

Geography

This manuscript provides guidance concerning how to use the Total Operating Characteristic (TOC) when (1) analyzing change through time, (2) ranking a categorical independent variable, and (3) constraining the extent for a gaining category. The illustrative variable is the marsh land-cover category in the Plum Island Ecosystems of northeastern Massachusetts, USA. The data are an elevation map and maps showing the land categories of water, marsh, and upland in 1938, 1971, and 2013. There were losses and gains near the edge of the marsh between 1938 and 1972 and between 1972 and 2013. The TOC curves show that marsh gained …

Drought As An Emergent Driver Of Ecological Transformation In The Twenty-First Century, Wynne E. Moss, Shelley D. Crausbay, Imtiaz Rangwala, Jay W. Wason, Clay Trauernicht, Camille S.

Cartwright, Robert K. Booth

Geography

Under climate change, ecosystems are experiencing novel drought regimes, often in combination with stressors that reduce resilience and amplify drought's impacts. Consequently, drought appears increasingly likely to push systems beyond important physiological and ecological thresholds, resulting in substantial changes in ecosystem characteristics persisting long after drought ends (i.e., ecological transformation). In the present article, we clarify how drought can lead to transformation across a wide variety of ecosystems including forests, woodlands, and grasslands. Specifically, we describe how climate change alters drought regimes and how this translates to impacts on plant population growth, either directly or through drought's interactions with factors …

Understanding The Roles Of Economy And Society In The Relative Risks Of Zoonosis Emergence From Livestock, Stephen Hinchcliffe, Alex Blanchette, Kin Wang (Ray) Chan, Chris Degeling, Jody Emel, Melissa Leach, Ian Scoones, Michael Winter

Geography

The emergence of zoonotic infections that can develop into pathogens of pandemic potential is a major concern for public health. The risks of emergence and transmission relate to multiple factors that range from land use to human-non-human animal contacts. Livestock agriculture plays a potentially significant role in those risks, shaping landscapes and providing hosts that can act as the source or amplifiers of emergent pathogens. The relative risks will be contingent upon the nature of those systems, with comparisons often made between intensive, indoor, biosecure systems and more extensive, outdoor, insecure systems. Microbiological, ecological and veterinary sciences provide useful entry …

Divergent Biophysical Responses Of Western United States Forests To Wildfire Driven By Eco-Climatic Gradients, Surendra Shrestha, Christopher A. Williams, Brendan M. Rogers, John Rogan, Dominik Kulakowski

Geography

Understanding vegetation recovery after fire is critical for predicting vegetation-mediated ecological dynamics in future climates. However, information characterizing vegetation recovery patterns after fire and their determinants over large geographical extents is limited. This study uses Moderate Resolution Imaging Spectroradiometer (MODIS) leaf area index (LAI) and albedo to characterize patterns of post-fire biophysical dynamics across the western United States (US) and further examines the influence of topo-climatic variables on the recovery of LAI and albedo at two different time horizons, 10 and 20 years post-fire, using a random forest model. Recovery patterns were derived for all wildfires that occurred between 1986 …

Soil Moisture Profile Estimation By Combining P-Band Sar Polarimetry With Hydrological And Multi-Layer Scattering Models, Anke Fluhrer, Thomas Jagdhuber, Carsten Montzka, Maike Schumacher, Hamed Alemohammad, Alireza Tabatabaeenejad, Harald Kunstmann, Dara Entekhabi

Geography

An approach for estimating vertically continuous soil moisture profiles under varying vegetation covers by combining remote sensing with soil (hydrological) modeling is proposed. The approach uses decomposed soil scattering components, after the removal of the vegetation scattering components from fully polarimetric P-band SAR observations. By comparing these with hydrological simulations, soil moisture profiles from the soil surface until a soil depth of 30 cm (assumed average P-band penetration depth) are estimated. Here, the hydrological model HYDRUS-1D, as a representative of any soil hydrological model, is employed to simulate an ensemble of realistic soil moisture profiles, which are used for a …

Increasing Mine Waste Will Induce Land Cover Change That Results In Ecological Degradation And Human Displacement, John R. Owen, Deanna Kemp, Alex M. Lechner, Michelle Ang Li Ern, Éléonore Lèbre, Gavin M. Mudd, Mark G. Macklin, Muhamad Risqi U. Saputra, Tahjudil Witra, Anthony J. Bebbington

Geography

Highlights

• Mining-induced displacement is a severely under researched social policy problem.
• Through global data sources and historic remote sensing we analyze this problem.
• The main output of most mining activity is hazardous waste.
• We confirm waste as the principal source of human displacement globally in mining.
• Resources to fuel urbanisation and energy transition targets will drive increases in waste.

Patterns Of Infringement, Risk, And Impact Driven By Coal Mining Permits In Indonesia, Tim T. Werner, Tessa Toumbourou, Victor Maus, Martin C. Lukas, Laura J. Sonter, Muhamad Muhdar, Rebecca K. Runting, Anthony J. Bebbington

Geography

Coal mining is known for its contributions to climate change, but its impacts on the environment and human lives near mine sites are less widely recognised. This study integrates remote sensing, GIS, stakeholder interviews and extensive review of provincial data and documents to identify patterns of infringement, risk and impact driven by coal mining expansion across East Kalimantan, Indonesia. Specifically, we map and analyse patterns of mining concessions, land clearing, water cover, human settlement, and safety risks, and link them with mining governance and regulatory infractions related to coal mining permits. We show that excessive, improper permit granting and insufficient …

Geography

We review the often-invisible powerful processes that drive social and ecological change in Amazonia, and the diverse peoples who inhabit its landscapes. It explores large-scale development ideologies of modernization, and the policy tools that were deployed to carry them out. Outlining general periods of macro policy shifts, we show the evolution of the framework for today’s complex interactions between large-scale agroindustry, mining, and hydrocarbons, and diverse small-scale livelihoods, as well as the clandestine and illicit economies of land grabbing, gold, coca and timber, and their operation in globalized and regional economies. While Pan-Amazonian governments have oscillated between authoritarian and democratic …

Growing Up Sustainable? Politics Of Race And Youth In Urbanplan, Copenhagen, Max Ritts, Rebecca Rutt

Geography

This paper considers how racialized youth in Denmark negotiate sustainability amid contexts marked by intersecting forms of economic restructuring, progressive neoliberalism, white ethno-nationalism, and green urban planning. Urbanplan is a low-income, notoriously “troubled” Copenhagen neighborhood where we conducted fieldwork for 7 months (2019-2020) with fifteen male youth, aged 17-21. Using ethnography, policy reviews, and interviews with city social workers, we explore how intimate experiences of nature, group-identity, and place attachment here relate to and depart from the structural forces actively reshaping the neighborhood. Our analysis combines Cindi Katz's intersectional political economy approach with recent work on green gentrification, Critical Utopian …

Methods To Compare Sites Concerning A Category’S Change During Various Time Intervals, Thomas Mumuni Bilintoh, Robert Gilmore Pontius, Aiyin Zhang

Geography

This paper presents new methods to analyze a category’s change through a time series of maps, even when the time intervals have inconsistent durations. The methods include an option to facilitate comparison among sites by expressing results as an annual percentage of each site’s unified size. A site’s unified size is the union of where the category exists at any of the site’s time points. The methods also specify gross losses, gross gains, eight trajectories, and three components: Quantity, Exchange, and Alternation. The illustrative application compares maps of the marsh category for three Long-Term Ecological Research sites: Plum Island Ecosystems …

Geopolitics And Geospatial Strategies: The Rise Of Regulatory Supply Chain Controls For Semiconductor Gpn In Japan, South Korea And Taiwan, Yuko Aoyama, Eunyeong Song, Shan-Yu Wang

Geography

In this article, we present an analysis of how East Asian states (specifically, Japan, South Korea and Taiwan) are adapting to the emerging geopolitical contexts of the 'great powers competition' between the United States and China. To the extent that the previous literature on GPN/GVC governance included the state as one of the extra-firm actors, geopolitics has not been explicitly dealt with in its role in shaping GPN/GVC governance. We build on the existing research on GPN/GVC governance and propose a shift in perspective, from one of cost-driven to diplomacy-driven governance. Taking the case of the semiconductor industry, we conduct …

'We' Instead Of 'Me': How Buen Vivir Indigenous Cosmopraxes Allow Us To Conceive Security Differently And Face Insecurities Together, Juliano Cortinhas, Yara Martinelli, Ricardo Barbosa

Student Publications [Scholarly]

Although Critical Security Studies (CSS) has done much to advance security debates, some shortcomings remain. Its excessive focus on the individual - which we term 'me' - reduces CSS' capacity to propose solutions to current global security problems such as pandemics and climate change. This paper contributes to the emerging scholarship on the potential of relational ontologies in Security Studies by introducing Buen Vivir Indigenous cosmopraxes into the debate. Indigenous cosmopraxes such as Sumak Kawsay, Suma Qamaña, and Teko Kavi, we argue, can inform CSS by providing alternative considerations to the pluriverse of ideas that address security crises. These cosmopraxes, …

Grappling With Real Property Supremacy In Us Urban Climate Finance, Julia Wagner, Mark Kear, Sarah Knuth, Sahar Zavareh Hofmann, Zac E. Taylor

Student Publications [Scholarly]

In US cities, drives to secure property value against climate risks have become a preoccupation for mainstream climate finance. This real property bias sidelines non-owners and inhabitants of historically marginalized housing types, limiting their capacity to prepare for and recover from climate change events. In this intervention, we survey major pathways of existing climate finance, before turning to emerging trends for residential ‘climate-proofing,’ retrofitting efforts that bring climate finance ‘home’ to the building level. Building on the concept of ‘real property supremacy,’ we demonstrate how resourcing climate response is limited by the privileging of real property in the structure and …
