Published: 2021-02-05
Subjects: Environmental Indicators and Impact Assessment, Environmental Sciences, Sustainability
Effects of the increasing use of motor vehicles are almost unnoticeable in large and congested megacities, urban areas, and metropolitan cities such as Mumbai and Delhi. Furthermore, a significant source of air pollution in several Indian cities is transportation. With the rapid growth in urbanization, industrialization, and modernization in such cities, alongside an increase in pollution, the [...]
The UK needs an open data portal dedicated to coastal flood and erosion hazard risk and resilience
Published: 2020-12-17
Subjects: Geographic Information Sciences, Geomorphology, Natural Resources Management and Policy, Nature and Society Relations, Sustainability
In the UK, coastal flooding and erosion are two of the primary climate-related hazards to communities, businesses, and infrastructure. To better address the ramifications of those hazards, now and into the future, the UK needs to transform its scattered, fragmented coastal data resources into a systematic, integrated, quality-controlled, openly accessible data portal. Such a portal would support [...]
Global Liquefied Natural Gas Expansion Exceeds Demand for Coal-to-gas Switching in Paris Compliant Pathways
Published: 2020-12-04
Subjects: Oil, Gas, and Energy, Sustainability
The shift from coal to natural gas (NG) in the power sector has led to significant reductions in carbon emissions. The shale gas revolution that led to this shift is now fueling a global expansion in liquefied natural gas (LNG) export infrastructure. In this work, we assess the viability of LNG expansion to reduce global carbon emissions through coal-to-gas switching in the power sector under [...]
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 [...]
ENSO Drives Child Undernutrition in the Global Tropics

In the absence of a federal geologic repository or consolidated, interim storage in the United States, commercial spent fuel will remain stranded at some 75 sites across the country. Currently, these include 18 “orphaned sites” where spent fuel has been left at decommissioned reactor sites. In this context, local communities living close to decommissioned nuclear power plants are increasingly [...]

Comparing patterns of hurricane washover into built and unbuilt environments
Published: 2020-10-23
Subjects: Geomorphology, Nature and Society Relations, Physical and Environmental Geography, Sustainability
Extreme geohazard events can change landscape morphology by redistributing huge volumes of sediment. Event-driven sediment deposition is typically studied in unbuilt settings – despite the ubiquity of occurrence and high economic cost of these geohazard impacts in built environments. Moreover, sedimentary consequences of extreme events in built settings tend to go unrecorded because they are [...]
