We introduced a new method to monitor wind turbine gearboxes using distributed fiber-optic technology. By attaching a single optical fiber to the gearbox, we tracked strain changes at high resolution, capturing gear movement, torque, and temperature in real time. This study demonstrated the link between torque and strain, enabling early fault detection. The approach offers a cost-effective way to improve gearbox reliability and reduce downtime, supporting more sustainable wind energy operations.

Both spatial and temporal information are important in agriculture. Information regarding the above-ground variables ever-increasing in density and precision. On the contrary, below-ground information lags behind and has been typically limited to time series. This study uses methods that map the subsurface spatial variability. A numerical simulations of above- and below water fluxes are then based on such spatial information and additional time-oriented datasets that are common in agriculture.

We propose an alternative electrode to perform Electrical Resistivity Tomography measurements in coarse blocky environments, such as rock glaciers. Compared to the traditional steel spike electrodes, which need to be hammered between the blocks, the proposed steel-net electrodes can be easily pushed between the builders by hand and then removed. Furthermore, the steel-net electrode weighs one-sixth of the steel spike, and is, therefore, easier to carry in challenging mountain environments.

Soil compaction resulting from inappropriate agricultural practices affects soil ecological functions, decreasing the water-use efficiency of plants. Recent developments contributed to innovative sensing approaches aimed at safeguarding soil health. Here, we explored how the most used geophysical methods detect soil compaction. Results, validated with traditional characterization methods, show the pros and cons of non-invasive techniques and their ability to characterize compacted areas.

Bentonite buffer surrounding the waste canister is a critical part of the multi-barrier system for high-level radioactive waste geological repositories that undergo heating from heat-emitting waste and hydration from the host rock. Thus, extensive research was conducted to study the alteration of bentonite due to heating and hydration under high temperatures (200 °C); this work provides valuable data for model validation.

We collated the Open Tension-disk Infiltrometer Meta-database (OTIM). We analysed topsoil hydraulic conductivities at supply tensions between 0 and 100 mm of 466 data entries. We found indications of different flow mechanisms at saturation and at tensions >20 mm. Climate factors were better correlated with near-saturated hydraulic conductivities than soil properties. Land use, tillage system, soil compaction and experimenter bias significantly influenced K to a similar degree to soil properties.

Short summary
European agriculture is vulnerable to weather extremes. Nevertheless, by choosing well how to manage their land, farmers can protect themselves against drought and peak rains. More than a thousand observations across Europe show that it is important to keep the soil covered with living plants, even in winter. A focus on a general reduction of traffic on agricultural land is more important than reducing tillage. Organic material needs to remain or be added on the field as much as possible.

Short summary
The study explores the partial root zone drying method, an irrigation strategy aimed at improving water use efficiency. We imaged the root–soil interaction using non-destructive techniques consisting of soil and plant current stimulation. The study found that imaging the processes in time was effective in identifying spatial patterns associated with irrigation and root water uptake. The results will be useful for developing more efficient root detection methods in natural soil conditions.
