A scalable framework for quantifying field-level agricultural carbon outcomes
Published: 2022-01-01
Subjects: Environmental Studies, Physical and Environmental Geography, Remote Sensing, Social and Behavioral Sciences
Agriculture contributes nearly a quarter of global greenhouse gas (GHG) emissions, which is motivating interest in certain farming practices that have the potential to reduce GHG emissions or sequester carbon in soil. The related GHG emission (including N2O and CH4) and changes in soil carbon stock are defined here as “agricultural carbon outcomes”. Accurate quantification of agricultural carbon [...]

Published: 2021-12-05
Subjects: Climate, Environmental Monitoring, Environmental Sciences, Meteorology, Physical and Environmental Geography
Recent advances in citizen weather station (CWS) networks, with data accessible via crowd-sourcing, provide relevant climatic information to urban scientists and decision makers. In particular, CWS can provide long-term measurements of urban heat and valuable information on spatio-temporal heterogeneity related to horizontal heat advection. In this study, we make the first compilation of a [...]
Geographically-resolved social cost of anthropogenic emissions accounting for both direct and climate-mediated effects
Published: 2021-11-17
Subjects: Atmospheric Sciences, Climate, Environmental Sciences, Physical and Environmental Geography, Sustainability
The magnitude and distribution of physical and societal impacts from long-lived greenhouse gases are insensitive to the emission source location; the same is not true for major co-emitted short-lived pollutants like aerosols. Here we combine novel global climate model simulations with established response functions to show that identical aerosols emitted from different regions (Brazil, China, [...]
Climate change, fire return intervals and the growing risk of permanent forest loss in boreal Eurasia
Published: 2021-11-15
Subjects: Climate, Environmental Indicators and Impact Assessment, Environmental Monitoring, Other Environmental Sciences, Physical and Environmental Geography, Remote Sensing, Spatial Science
Climate change has driven an increase in the frequency and severity of fires in Eurasian boreal forests. A growing number of field studies have linked the change in fire regime to post-fire recruitment failure and permanent forest loss. In this study we used four burnt area and two forest loss datasets to calculate the landscape-scale fire return interval (FRI) and associated risk of permanent [...]

Ensuring taught fieldwork is a positive, generative, collective, and valuable experience for all participants requires considerations beyond course content. To guarantee safety and belonging, participants’ identities (backgrounds and protected characteristics) must be considered as a part of fieldwork planning and implementation. Furthermore, getting fieldwork right is an important step in [...]
Creating a climate changed future with the sea level rise interactive- fiction game ‘Lagos2199’

Subjects: Climate, Education, Environmental Education, Environmental Sciences, Environmental Studies, Geographic Information Sciences, Geography, Instructional Media Design, International and Area Studies, Nature and Society Relations, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Other Earth Sciences, Other Environmental Sciences, Physical and Environmental Geography, Physical Sciences and Mathematics, Science and Mathematics Education, Sustainability
Story-based futures serve an important role in climate change scenario development. Stories are particularly useful in exploring sea level rise possibilities, since we know many coastal areas are specifically vulnerable to accelerating rises in sea level. This discrete change in coastline is different from most other climate change impacts, and offers a clear basis for scientifically-informed, [...]
Knowing the whole world from the top of a mountain: from orderly systematization to complex explanatory systems
Published: 2021-06-29
Subjects: Earth Sciences, Physical and Environmental Geography, Systems Biology
Fast and fascinating changes in views on nature and systems occurred around 1800, for example in the works of Alexander von Humboldt. While Humboldt rarely used the word system, he searched for the pattern-forming forces of nature by gruesome experiments on animals, including himself, and then drew a map of a mountain that became the basis of biogeography. What did ‘system’ mean then and now, how [...]
Evaluating the Economic Fairways for Hydrogen Production in Australia
Published: 2021-05-20
Subjects: Chemical Engineering, Natural Resource Economics, Natural Resources Management and Policy, Physical and Environmental Geography, Power and Energy, Water Resource Management
Assessments of hydrogen project viability typically focus on evaluating specific sites for development, or providing generic cost-estimates that are independent of location. In reality, the success of hydrogen projects will be intimately linked to the availability of local energy resources, access to key infrastructure and water supplies, and the distance to export ports and energy markets. In [...]
The disaster trap: cyclones, tourism, colonial legacies, and the systemic feedbacks exacerbating disaster risk
Published: 2021-05-04
Subjects: Geography, Human Geography, Nature and Society Relations, Physical and Environmental Geography
The long, open-ended period of recovery from a disaster event is the phase of a disaster that the interdisciplinary field of disaster studies struggles to understand. In the process of rebuilding, places do not simply reset – they transform, often in ways that confound any reduction of disaster risk, instead making people and settings more vulnerable to future hazard events. Reducing disaster [...]
High resolution, annual maps of field boundaries for smallholder-dominated croplands at national scales

Analysis of off-site economic costs induced by runoff and soil erosion: example of two areas in the northwestern European loess belt for the last two decades (Normandy, France)
Published: 2021-01-21
Subjects: Physical and Environmental Geography
While soil erosion and runoff physical aspects are widely addressed in the literature, few studies have focused on the economical dimension. However, it is essential to consider this dimension to conduct appropriate land use management policies. Erosion and runoff are known to result into on-site and off-site impacts. A fully exhaustive analysis of erosion and runoff economic costs may be [...]

Subjects: Environmental Sciences, Environmental Studies, Geography, Human Geography, Nature and Society Relations, Oceanography and Atmospheric Sciences and Meteorology, Physical and Environmental Geography, Physical Sciences and Mathematics, Social and Behavioral Sciences
Anthropogenic activity is changing Earth’s climate and ecosystems in ways that are potentially dangerous and disruptive to humans. Greenhouse gas concentrations in the atmosphere continue to rise, ensuring these changes will be felt for centuries beyond 2100, the current benchmark for prediction. Estimating the effects of past, current, and potential future emissions to only 2100 is therefore [...]
Operationalising coastal resilience to flood and erosion hazard: A demonstration for England
Published: 2020-12-02
Subjects: Geomorphology, Nature and Society Relations, Physical and Environmental Geography, Sustainability
Resilience is widely seen as an important attribute of coastal systems and, as a concept, is increasingly prominent in policy documents. However, there are conflicting ideas on what constitutes resilience and its operationalisation as an overarching principle of coastal management remains limited. In this paper, we show how resilience to coastal flood and erosion hazard could be measured and [...]
