In addition, as we would expect, landslide studies are numerous in Italy, one of the world's most mountainous countries, where 42 % of the country is considered Bhilly^and 35 % is considered Bmountainous^ (Salvati and Carlucci 2015).

“…Global grasslands store 10-30% of soil organic C (SOC) with a sequestration rate of 0.5 Pg C yr À1 and harbor more than 10% of terrestrial biomass C (Follett & Reed, 2010;Qiu et al, 2013). Currently, a majority of grasslands are experiencing overgrazing (Salvati & Carlucci, 2015), which not only threatens the biodiversity and stability of grasslands, but also alters ecosystem structure and functioning, leading to increased C and N losses (Knops & Tilman, 2000;Stavi et al, 2008;Fornara et al, 2011;Liu et al, 2015).…”

Livestock grazing activities potentially alter ecosystem carbon (C) and nitrogen (N) cycles in grassland ecosystems. Despite the fact that numerous individual studies and a few meta-analyses had been conducted, how grazing, especially its intensity, affects belowground C and N cycling in grasslands remains unclear. In this study, we performed a comprehensive meta-analysis of 115 published studies to examine the responses of 19 variables associated with belowground C and N cycling to livestock grazing in global grasslands. Our results showed that, on average, grazing significantly decreased belowground C and N pools in grassland ecosystems, with the largest decreases in microbial biomass C and N (21.62% and 24.40%, respectively). In contrast, belowground fluxes, including soil respiration, soil net N mineralization and soil N nitrification increased by 4.25%, 34.67% and 25.87%, respectively, in grazed grasslands compared to ungrazed ones. More importantly, grazing intensity significantly affected the magnitude (even direction) of changes in the majority of the assessed belowground C and N pools and fluxes, and C : N ratio as well as soil moisture. Specifically,light grazing contributed to soil C and N sequestration whereas moderate and heavy grazing significantly increased C and N losses. In addition, soil depth, livestock type and climatic conditions influenced the responses of selected variables to livestock grazing to some degree. Our findings highlight the importance of the effects of grazing intensity on belowground C and N cycling, which may need to be incorporated into regional and global models for predicting effects of human disturbance on global grasslands and assessing the climate-biosphere feedbacks.

“…Currently, grassland C dynamics are strongly impacted by grazing (McSherry & Ritchie, ; Zhou, Zhou, He, et al, ) and global climate change (e.g., warming, elevated CO 2 , increased precipitation, drought, N fertilization; Yuan & Chen, ; Zhou, Zhou, Shao, et al, ; Zhou, Zhou, Nie, et al, ). Because most global grasslands are grazed (Salvati & Carlucci, ), grazing is an important control on global C processes, including C storage and release (Frank & Groffman, ; McSherry & Ritchie, ). In addition, a variety of factors associated with global climate change (e.g., warming, drought) also alters grassland C dynamics in diverse ways (Bradford et al, ; Yuan & Chen, ).…”

Predicting future carbon (C) dynamics in grassland ecosystems requires knowledge of how grazing and global climate change (e.g., warming, elevated CO2, increased precipitation, drought, and N fertilization) interact to influence C storage and release. Here, we synthesized data from 223 grassland studies to quantify the individual and interactive effects of herbivores and climate change on ecosystem C pools and soil respiration (Rs). Our results showed that grazing overrode global climate change factors in regulating grassland C storage and release (i.e., Rs). Specifically, grazing significantly decreased aboveground plant C pool (APCP), belowground plant C pool (BPCP), soil C pool (SCP), and Rs by 19.1%, 6.4%, 3.1%, and 4.6%, respectively, while overall effects of all global climate change factors increased APCP, BPCP, and Rs by 6.5%, 15.3%, and 3.4% but had no significant effect on SCP. However, the combined effects of grazing with global climate change factors also significantly decreased APCP, SCP, and Rs by 4.0%, 4.7%, and 2.7%, respectively but had no effect on BPCP. Most of the interactions between grazing and global climate change factors on APCP, BPCP, SCP, and Rs were additive instead of synergistic or antagonistic. Our findings highlight the dominant effects of grazing on C storage and Rs when compared with the suite of global climate change factors. Therefore, incorporating the dominant effect of herbivore grazing into Earth System Models is necessary to accurately predict climate–grassland feedbacks in the Anthropocene.
