Anthropogenic activities have dramatically altered the global nitrogen (N) cycle. Atmospheric N deposition, primarily from combustion of biomass and fossil fuels, has caused acidification of precipitation and freshwater and triggered intense research into ecosystem responses to this pollutant. Experimental simulations of N deposition have been the main scientific tool to understand ecosystem [...]

Intensive agriculture and densely populated areas represent major sources of nutrient pollution for European inland and coastal waters, altering the aquatic ecosystems and affecting their capacity to provide ecosystem services and support economic activities. Ambitious water policies are in place in the European Union (EU) for protecting and restoring aquatic ecosystems under the Water Framework [...]

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 [...]

Ordination is the name given to a group of methods used to analyze multiple variables without preceding hypotheses. Over the last few decades the use of these methods in Earth science in general, and notably in analyses of sedimentary sources, has dramatically increased. However, with limited resources oriented towards Earth scientists on the topic, the application of ordination analysis is at [...]

The 880 million agricultural workers of the world are especially vulnerable to increasing heat stress due to climate change, affecting the health and income of individuals, while also decreasing global economic productivity. In this study, we focus on rice harvests across Asia and estimate the future impact on labour productivity by considering changes in climate at the time of the annual [...]

Loose sand has a wide variety (over 200) of industrial usage where most of the sand is used in infrastructure. Due to its low cost / high benefit nature and international high demand, worldwide examples of excessive sand mining caused complete destruction of habitats and forcing natives change living practices or even to migrate. Sand mining is one of the most controversial and rapidly growing [...]

The main goal of the International Meeting “40 Years of the 1980 Azores Earthquake” was promoting a reflection of the earthquake of January 1st, 1980, and the advances since them on topics like seismology, seismic hazard, and risk, building rehabilitation and public policies. Nevertheless, due to the COVID-19 outbreak, the organizing committee decided that the meeting should be online and [...]

The paper presents supplementary information about the framework and method for the socio-technical multi-criteria evaluation (STMCE) of spent fuel management strategies (Sci Total Environ, In press; Available on EarthArXiv at DOI:10.31223/X5459S). The STMCE approach consists of (i) a multi-criteria evaluation that provides an ordinal ranking of alternatives based on a list of criterion [...]

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 [...]

Methane (CH4) emissions from oil and natural gas (O&NG) systems are an important contributor to greenhouse gas emissions. In the United States (US), recent synthesis studies of field measurements of CH4 emissions at different spatial scales are ~1.5x-2x greater compared to official Environmental Protection Agency (EPA) greenhouse gas inventory (GHGI) estimates. Site-level field studies have [...]

This work investigates the relationship between urbanization, population density and meteorological variables (temperature & precipitation) on groundwater storage in India during the period January'2003 to January'2017. Variations in groundwater storage have been analysed using Gravity Recovery and Climate Experiment (GRACE) derived variations of Terrestrial Water Storage (TWS). In the first part [...]

Remote northern (NH) and southern hemisphere (SH) lake sediment and peat records of mercury (Hg) deposition show a ×3 to ×5 Hg enrichment since pre-industrial times (<1880AD), leading to the common perception that global atmospheric Hg enrichment is moderate and uniform. Anthropogenic Hg emission in the NH is, however, approximately four times higher than in the SH. Here we reconstruct [...]

The development of bioeconomy needs to accelerate in order to get rid of fossil fuels and products. The production of bio-based products and renewable energy sources from the thermochemical conversion of biomass can be a sustainable alternative. Pyrolysis is one of the thermochemical processes that can convert biomass into liquid (bio-oil), solid (biochar) and gaseous (non-condensable gases) [...]

Many politicians and media personalities continue to cast doubt on the idea that anthropogenic global warming (AGW) – the primary driver of current global climate change – could possibly be behind the growing frequency and severity of extreme weather events – the droughts, heatwaves, flooding, etc. that are every year breaking 100 year or greater historical records. This takes the form not just [...]
