“…Indeed, the socio‐economic and infrastructural development pressures associated with the needs of the rapidly growing human population could also exacerbate the loss of the Grassland Biome (Goble et al, 2014 ; Greyling, 2012 ; Kanianska, 2016 ; Laurance et al, 2014 ). We suggest that since grasslands constitute an important global carbon storage (Yuan et al, 2021 ), there is urgent need for mitigating fragmentation as part of climate change adaptation.…”

Olea europaea subsp. africana (Mill.) P.S. Green (medium-sized tree species known as "African wild olive"), provides important ecological goods and services for sustaining frugivores in the grassland biome in South Africa. We speculate that O. europaea subsp. africana's population has been declining due to habitat loss and exploitation for domestic benefits suggesting an unrecognized conservation threat. Therefore, the study aimed to investigate the anthropogenic conservation threats for O. europaea subsp. africana in the Free State, South Africa and to determine the potential importance of seed dispersal effectiveness in the restoration of the species in the study area. Overall, the results showed that 39% of the natural habitat range has been transformed by human-mediated activities. Agricultural activities accounted for 27%, while mining activities and human settlement accounted for 12%, of natural habitat loss. In support of the study predictions, seeds of O. europaea subsp. africana had significantly higher germination and germinated faster after passing through the mammal gut (i.e., 28% and 1.49 per week), compared to other seed treatments (i.e., over 39 weeks). However, there were no statistically significant differences between seed germination of the bird-ingested seeds, with intact fruits as the experimental control, although both were significantly greater than the de-pulped seeds. Potential seed dispersal distances by birds were relatively larger, ranging from 9.4 km to 53 km, than those of mammals (1.5 km-4.5 km). We propose that the O. europaea subsp. africana's habitat range may have been declining, and since it is a keystone plant species, we recommend that the complementary seed dispersal services by birds and mammals could be important for its recruitment and restoration in the degraded habitat.

“…Information on the spatiotemporal variability of SOCD is critical for understanding the global carbon budget and adjusting land-use management policies, around CO 2 emission reduction and global warming mitigation . Grasslands store approximately 34% of the total soil carbon and 10% of SOC in global terrestrial ecosystems (Scurlock et al, 2002;Corona et al, 2016;Yuan et al, 2021). With a mean SOCD of 7.6-14.1 kg C m −2 and SOCS of 278.9-591.5 Pg, global grasslands have strong carbon sequestration potential and play a critical role in regulating the global carbon cycle and climate (King et al, 1997;Prentice et al, 2001;Piao et al, 2009;Wei and Fang, 2009;.…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

“…While considerable efforts in understanding grassland restoration projects' impacts on carbon storage have increased, several methods have been widely proposed and mostly focused on the effects of vegetation indices and ecological models, driven by common approaches with remote sensing products and field experiment data (Khorchani et al, 2022; Li, Cao, et al, 2021; Yuan et al, 2021). For instance, Li, Cao, et al (2021), quantified the spatiotemporal changes in the annual maximum grassland NDVI (Normalized Difference Vegetatio) after the implementation of ecological restoration projects on the northern Tibetan Plateau.…”

Investigating the cost‐effective and low‐carbon pathways for grassland ecological restoration projects is vital to achieving carbon neutrality and Sustainable Development Goals. To fill the gap of incorporating ecological and socioeconomic systems of ecological restoration projects, this study established a cost‐benefit evaluation framework that integrated the carbon footprint based on life cycle assessment and a carbon price measurement model based on the Slack‐Based Measure‐Data Envelopment Analysis model. Taking a ‘Returning Grazing Land to Grassland Project’ on the Qinghai‐Tibet Plateau as a case, this study quantified the carbon footprint of three different ecological measurements, including fences construction (released 107 kgCO2‐eq·hm−2 and absorbed 322 kgCO2‐eq·hm−2), degenerated grassland improvement (released 1080 kgCO2‐eq·hm−2 and absorbed 580 kgCO2‐eq·hm−2) and artificial grassland planting (released 2540 kgCO2‐eq·hm−2 and absorbed 6540 kgCO2‐eq·hm−2). Raw material production was the largest emitter. In addition, we calculated the carbon price in the grassland ecosystem by the carbon price measurement model, at 1.06 yuan·kgCO2‐eq−1 on average during 2011–2018. In the cost‐benefit analysis, the total carbon sequestration benefits (8.90 × 106 yuan) outweighed the total carbon emission costs (4.26 × 106 yuan). Optimizing the usage and transportation of building materials and the application of fertilizer can benefit carbon emission mitigation and enhancement of carbon sequestration capacity in grassland. This study provided a theoretical basis for ecological restoration projects and grassland carbon pricing mechanisms aiming for sustainable management.
