The State of Global Catastrophic Risk Research: A Bibliometric Review
Published: 2024-11-30
Subjects: Agriculture, Biodiversity, Environmental Sciences, Environmental Studies, Food Science, Geography, Other Life Sciences
The global catastrophic risk (GCR) and existential risk (ER) literature focuses on analysing and preventing potential major global catastrophes including a human extinction event. Over the past two decades, the field of GCR/ER research has grown considerably. However, there has been little meta-research on the field itself. How large has this body of literature become? What topics does it cover? [...]
The gendered nature of climate change impacts in the Republic of the Marshall Islands
Published: 2024-11-15
Subjects: Geography
Empirical evidence on the gendered impacts of climate change is limited, particularly in the islands of the Pacific. This paper presents findings from fieldwork in the Republic of Marshall Islands that engaged with 1362 participants from 15 atolls. The data provides four clear findings. First, that men and women’s livelihoods are heavily impacted by climate change, with reduced incomes shifting [...]
Sensing the dynamic nature of fragmented croplands in India through earth observation: a comprehensive review
Published: 2024-11-09
Subjects: Agriculture, Earth Sciences, Environmental Sciences, Food Science, Geography, Nature and Society Relations, Physical and Environmental Geography, Remote Sensing, Spatial Science
Fragmentation or the breakdown of landholdings to smaller parcels has an adverse impact on crop yields and productivity because of its uneconomic operational sizes. This comprehensive review reflects the insights into the complex dynamics of small landholding (SLs) in India by leveraging earth observation (EO) based sensing technology through synthesizing existing literature, methodologies and [...]
ml4xcube: Machine Learning Toolkits for Earth System Data Cubes

Subjects: Computer and Systems Architecture, Computer Engineering, Engineering, Geography, Remote Sensing, Social and Behavioral Sciences
Rapidly changing climate conditions and the increase in extreme events are posing severe challenges to human life and infrastructure, requiring sophisticated analytical capabilities for hazard prediction and disaster risk management. Earth System Data Cubes (ESDCs) have become an essential tool in Earth System Sciences (ESS) by organizing large-scale, multivariate environmental datasets into a [...]
Virtual laser scanning of dynamic scenes (VLS-4D): Current approaches and future perspectives in remote sensing
Published: 2024-10-07
Subjects: Computer Sciences, Earth Sciences, Environmental Sciences, Geographic Information Sciences, Geography, Numerical Analysis and Scientific Computing, Physical and Environmental Geography, Remote Sensing
Virtual laser scanning (VLS) has proven to be a useful tool for survey planning, method development and training data generation in a variety of areas of Earth and environmental sciences. Until recently, most applications have used static representations of the real or a fictive environment, neglecting the inherent dynamics of our world, that also affect Light Detection and Ranging (LiDAR) [...]
Adaptive capacity in Pacific Islands: responding to coastal and climatic change in Nagigi village, Fiji
Published: 2024-10-02
Subjects: Geography
Coastal communities across the Pacific are increasingly recognized as places of priority for climate adaptation. Pacific Island communities are developing and using strategies to adapt their lives and livelihoods to climatic and environmental risks. Highlighting the case study of Nagigi village, Fiji, we identify adaptation responses to multiple environmental and socio-economic pressures [...]
The Socioeconomic Impacts of Sea Level Rise and Phragmites australis in the New Jersey Meadowlands
Published: 2024-10-01
Subjects: Geography, Natural Resource Economics, Nature and Society Relations, Plant Sciences
Sea level rise is one of the most alarming impacts of climate change and is projected to have devastating economic consequences for coastal communities such as increased flood damage, lost economic productivity, and decreased property values. To measure this impact in the New Jersey Meadowlands, an urban estuary ecosystem, I used a digital elevation model (DEM) to create inundation maps modeling [...]
Private protected areas exhibit greater bias towards unproductive land compared to public protected areas
Published: 2024-09-13
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Studies, Geography, Life Sciences, Social and Behavioral Sciences
Globally, private protected areas (PPAs) have become an important tool for biodiversity conservation. While they are expanding in size and number, there is limited evidence on their potential impact on avoiding biodiversity loss, and how this impact compares to the public protected areas (PAs). The impact of protection is measured as the actual biodiversity outcome within the area protected [...]
Deciphering Climate Variability Trends: Unveiling the Impact on Household Staple Crop Productivity in East Wallaga Zone, Ethiopia
Published: 2024-09-05
Subjects: Geography
This study looks at how Ethiopia's East Wallaga Zone's staple crop yields are affected by climate variability between 1990 and 2022. The main goal is to evaluate the effects of temperature and precipitation variations on the production of important crops, namely wheat and teff, in the highlands, midlands, and lowlands of various agroecological zones. The Ethiopian Meteorological Institute, [...]
Comprehensive Assessment of Flood Risk and Vulnerability for Essential Facilities: Iowa Case Study
Published: 2024-08-02
Subjects: Civil and Environmental Engineering, Engineering, Environmental Studies, Geographic Information Sciences, Geography, Social and Behavioral Sciences, Spatial Science
Of all natural disasters that occur on this planet, flood events are universally one of the most common and most destructive. As climate change and human actions continue to cause the occurrence of flood events to rise, it becomes increasingly important that the effects of flooding are analyzed and understood. In this study, nine different types of critical amenities in the state of Iowa (such as [...]
Mercury records from natural archives reveal ecosystem responses to changing atmospheric deposition
Published: 2024-05-15
Subjects: Atmospheric Sciences, Environmental Sciences, Geochemistry, Geography, Physical and Environmental Geography
Global ecosystems face mercury contamination, yet long-term data is scarce, hindering understanding of ecosystem responses to atmospheric Hg input changes. To bridge data gap and assess ecosystem responses, we compiled and compared a mercury accumulation database from peat, lake, ice, and marine deposits worldwide with atmospheric mercury deposition modeled by GEOS-Chem, focusing on trends, [...]
