A study by Snoussi et al., 2024 proposes a methodology for evaluating excavated material's environmental, geotechnical, and agronomical properties to determine its ecological reuse potential, particularly for constructing soil in urban green infrastructure. Through the SWOFI framework (Safety, Workability, Fertility, Infiltrability), the authors characterised a non-cohesive sedimentary parent rock with a sandy loam texture from Bou Argoub in Tunisia. The method successfully assessed the material’s pollution hazard, compaction sensitivity, and fertility showcasing a novel integrated approach for sustainable soil construction in urban landscapes.

Grazing pressure in savannah rangelands increases the possibility of desertification and woody plant encroachment under different land management. As such, early warning shift indicators of degraded rangelands are required. Zimmer et al., 2024 conducted a study on the arid savanna rangelands on Arenosols in Namibia and focussed on soil organic carbon (SOC) and carbon isotopes (δ13C) as indicators. Results show lower SOC stocks on communal rangelands compared to freehold farms, with correlations between SOC stocks and vegetation cover types. The findings emphasize the importance of considering soil properties such as SOC in land management practices to assess and mitigate soil degradation risks in savanna ecosystems

Artificial grassland restoration can be an effective method when applied to severely degraded grassland in alpine areas, however, their effects on slope runoff and sediment yield are still unclear. Qian et al., 2024 studied the effects of artificial restoration and degradation on the runoff sediment process in three areas and found that artificial grassland can significantly reduce runoff and sediment yield compared to alpine meadows and severely degraded alpine meadows. The study underscores the importance of plant and soil characteristics in erosion processes, highlighting the effectiveness of artificial grassland in mitigating soil erosion through improved soil conditions and enhanced vegetation coverage, with implications for restoration efforts in alpine regions.

This multi-city, multi-country One Earth Research Article shows that Paris Agreement-aligned climate action (SDG 13) is needed to avoid increasing ozone-related* deaths (SDG 3) because greener energy production is also cleaner pollution-wise. These actions will help make cities and communities more sustainable (SDG 11). *Some greenhouse gases, and many co-emitted pollutants from fossil-fuel burning, contribute to ozone production near ground level where it is a harmful pollutant.
