In Alaska, soil is warming faster in regions with continuous permafrost

,
A study tracks permafrost temperatures from 1997 to 2023, providing new data to forecast thaw and plan infrastructure. Greater depth does not slow the warming trend
An agrivoltaic installation, different from the one examined in the study. During the construction of agrivoltaic systems, designated routes for machinery, temporary ground protection and working in dry conditions can help protect the soil.

For agrivoltaic systems, soil protection must begin during construction

, ,
A German study finds severe soil compaction even in the areas available for cultivation between solar panels. Soil protection measures during construction are essential, particularly in sandy soils, which struggle to recover
For decades, geomorphologists have been trying to understand how Arctic terraces form spontaneously, as a result of the extremely slow movement of surface ground caused by permafrost thawing.

A fluid could explain the mystery of permafrost terraces

,
For decades, scientists have struggled to explain how Arctic permafrost terraces form spontaneously. A new model suggests that their origin may lie in the same physical principles that generate waves in complex fluids
In the south-western United States, climate change and the build-up of plant matter are fuelling increasingly extreme wildfires. Photo: Eric Coulter, Public Domain Mark 1.0 UniversalEric Coulter, Public Domain Mark 1.0 Universal

In California, the most devastating wildfires are the new normal

Uno studio mostra come il cambiamento climatico e la gestione delle foreste abbiano trasformato la natura prevalente degli incendi. Dal 2012 sono più comuni i roghi ad alta intensità, con conseguenze ambientali ed economiche sempre più gravi
The LandISPortal platform currently contains over 250,000 field observations and more than 30,000 detailed descriptions of soil profiles, as well as hundreds of specialist publications and thematic maps.

A new index measures soil health in mangrove forests

, ,
Brazilian researchers have developed an indicator to measure the ability of mangroves to provide ecosystem services, ranging from biodiversity conservation to carbon sequestration. The greater the soil degradation, the lower the score
Climate change is making Arctic soil more permeable, altering the amount of water that can be stored and transmitted. In coastal areas, rising sea levels will further increase groundwater levels, leading to saltwater intrusion.

It isn’t just a matter of melting ice: here’s how climate change is reshaping Arctic aquifers

,
Beneath the surface of the Arctic permafrost, an entire hydrological system is reorganizing. A Canadian study reveals where the soil will become drier and where moisture will increase
In China, vegetation restoration has reduced soil erosion from nearly 17.7 tons per hectare to less than 14 between 1990 and 2020. Image: PickPik Royalty-Free photoPickPik Royalty-Free photo

Vegetation restoration has curbed soil erosion in China (at least so far)

,
According to research, soil regeneration in China has significantly reduced land erosion over the last 30 years. More extreme rainfall in the future, however, will raise the risks
A study has proposed a framework for assessing European soil quality in a comprehensive manner by identifying quality indicators. Photo: Easy-Peasy.AI Free to useEasy-Peasy.AI Free to use

An integrated approach is needed for EU soil quality monitoring

,
A new study reviews different soil assessment schemes. The “binary” system is the most suitable for macro evaluation. But tools for local investigations are also needed
Grasslands are home to a wide variety of plant species and provide numerous ecosystem services, such as carbon sequestration, support for pollinators and grazing for livestock. But they are also some of thh most threatened ecosystems due to human activities, including land use change and intensive agricultural practices.

Study reveals how much nitrogen grasslands can tolerate

, ,
According to researchers, applying more than 80 kg of nitrogen per hectare in a year would make grasslands “functionally poor, highly unstable and vulnerable to extreme weather events”
