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.
Ginzky 2024 discusses the ongoing legislative process in Germany to amend the soil protection act, addressing climate change, biodiversity maintenance, and other challenges, with the support of the current government. The paper outlines the societal importance of soils, challenges, current legislation shortfalls, proposed regulatory approaches including ongoing EU deliberations, and strategies for gaining political support considering ecological and social services, as well as competing interests.
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
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.
Soil systems play a key role in the fight against climate change. A paper, produced by Rubio et al., 2024, highlights the importance of soil management and land conservation for sustainable use of resources. It calls for a comprehensive vision recognizing soil's socio-economic benefits and ecological functions, urging for radical environmental, social, and economic shifts to address climate change responsibly for present and future generations, in alignment with initiatives like the European Green Deal and the United Nations Sustainable Development Goals.
Areas prone to drought and land degradation need effective water management plans to secure food production. Methods such as hydrological modelling and digital soil mapping can aid in evaluating water availability (water content and water stress). A study by Horta et al., 2023 examined the use of a global and local soil hydraulic properties (SHP) dataset to simulate soil-water balance at a regional scale in Portugal and found that the SHP dataset is a key factor to consider. The results showed that the choice between global and local SHP datasets significantly impacts the accuracy of soil-water balance simulations, influencing irrigation schedules and potentially jeopardizing crop production and soil quality, particularly in Mediterranean conditions.
The objective of the meta-analysis is to identify impacts on various sectors, adaptation strategies, and the challenges of climate change in the Ethiopian context.
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.
It is largely understood that climate mitigation (SDG 13) requires phasing out fossil fuels and switching to renewable energy sources which produce electricity (SDG 7). Is it better to directly electrify by e.g., developing electric cars, stoves, and freight, or to indirectly electrify by using renewable electricity to produce alternative fuels like hydrogen to power cars, stoves, etc.? This One Earth Research Article shows via modeling that for the EU an hybrid approach is optimal, with cars and stoves being electrified but shipping and chemical industry transitioned to synthetic fuels.
The United Nations urges governments to promote sustainable, healthy diets to combat undernutrition, obesity, and climate change. This paper examines policy insights from high-income countries (HICs) and their applicability to low- and middle-income countries (LMICs). Alternative proteins (AP) should be affordable, locally sustainable, and culturally acceptable. Food-based dietary guidelines (FBDGs) should guide AP product development, ensuring they complement traditional proteins. Harmonizing multisectoral policies is crucial for LMICs to achieve a protein transition and food systems transformation by 2050.
