The aridity Index under global warming

open access: yesEnvironmental Research Letters, 2019
Aridity is a complex concept that ideally requires a comprehensive assessment of hydroclimatological and hydroecological variables to fully understand anticipated changes. A widely used (offline) impact model to assess projected changes in aridity is the

Impacts of Climate Variability and Drought on Surface Water Resources in Sub-Saharan Africa Using Remote Sensing: A Review

open access: yesRemote Sensing, 2020
Climate variability and recurrent droughts have caused remarkable strain on water resources in most regions across the globe, with the arid and semi-arid areas being the hardest hit.

The 4.2 ka Event and the End of the Maltese “Temple Period”

open access: yesFrontiers in Earth Science, 2022
The small size and relatively challenging environmental conditions of the semi-isolated Maltese archipelago mean that the area offers an important case study of societal change and human-environment interactions.

Nitrogen addition has a minor effect on aridity thresholds for soil nematodes at the global scale

open access: yesGeoderma
Soil nematodes are regulated by soil moisture, with a global aridity threshold identified for total nematode diversity. Nitrogen (N) deposition also influences soil nematodes, but its effect on their aridity threshold remains unclear.

Cool Kitchen: Processing Starch and Eggshell Powder into Sustainable Coatings for Passive Daytime Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A food‐grade cooling composite made from starch and recycled eggshell powder offers a scalable, ultra‐low‐cost solution for passive daytime radiative cooling. Easily prepared using basic kitchen tools, this material empowers communities, even in areas with limited infrastructure, to stay cooler during worsening summer heat waves.

Aridity Trends in Central America: A Spatial Correlation Analysis

open access: yesAtmosphere, 2020
Trend analyses are common in several types of climate change studies. In many cases, finding evidence that the trends are different from zero in hydroclimate variables is of particular interest.

Predation on sentinel prey increases with increasing latitude in Brassica‐dominated agroecosystems

open access: yesEcology and Evolution, 2022
In natural ecosystems, arthropod predation on herbivore prey is higher at lower latitudes, mirroring the latitudinal diversity gradient observed across many taxa.

Photothermal Macroporous Lignin Cryogels for Off‐Grid, Continuous Atmospheric Water Collection via Interlayer Heat Recovery

open access: yesAdvanced Functional Materials, EarlyView.
Photothermal, macroporous lignin‐based cryogels are engineered to convert sunlight into low‐grade heat. Integrated as stacked beds in a drum‐type device, a thin copper interlayer transfers waste heat between beds, enabling interlayer heat recovery and continuous solar cycling.

Saline and Arid Soils: Impact on Bacteria, Plants, and Their Interaction

open access: yesBiology, 2020
Salinity and drought are the most important abiotic stresses hampering crop growth and yield. It has been estimated that arid areas cover between 41% and 45% of the total Earth area worldwide.
