“…On the contrary, STP could improve the economy of low‐income farmers both by increasing animal production and by receiving payments from the environmental services (if local policies foster such incentives) and, at the same time, mitigate global warming. SPS can also improve the hydrological cycle and promote sustainable livestock production systems that help food sovereignty (Hoosbeek et al, 2018; Hou, 2021). Other studies have also documented that tree inclusion protects the soil from runoff and erosion and can lead to a more closed nutrient cycle and, therefore, more efficient use of plant resources (Smith et al, 2016).…”

“…Our results reaffirm that STP is an environmentally, economically and socially more sustainable animal production strategy than GM. SPS strengthen the performance of the livestock production systems, resilience and their adaptive capacity to climate change, the essential prerequisites to achieve the Sustainable Development Goals (1, 2, 3, 6, 8, 9, 11, 12, 13, 15 and 17) proposed by the United Nations (Apolinario et al, 2016; Hou, 2021; UN, 2019). However, in Mexico, despite the economic and socio‐environmental benefits that SPS offer, they have not been considered in agricultural development plans, as productive strategies balanced with the conservation of resources and the environment, including those related to climate change.…”

“…Changes in land use and management practices significantly alter soil organic carbon (SOC) storage due to the changes in the rate of carbon input and losses (Gava et al, 2021; Li et al, 2021). Therefore, enhancing SOC stocks is a promising measure to mitigate climate change, as well as enhancing soil biodiversity, immobilizing some toxic residues and ensuring food security (Hou, 2021).…”

Silvopastoral systems have great potential for storing carbon because of carbon assimilation in tree woody biomass, carbon input through litterfall and below‐ground carbon turnover. In this study, we quantified and compared the carbon stocks at livestock ranches in Tabasco, Mexico, containing either scattered trees in grazing pastures (STP) or grass monocultures. Sampling plots were randomly established at each ranch where the above‐ and below‐ground carbon stocks, carbon input from litterfall, grass production and arboreal biomass growth were measured. We found that silvopastoral systems stored an average of 257.45 Mg ha−1 of soil organic carbon (SOC) compared to 119.17 Mg SOC ha−1 at grass monoculture ranches (to 30 cm depth); silvopastoral systems also stored 44.64 Mg C ha−1 in wood biomass; and, grass monocultures had greater cumulative grass biomass production. Overall, it is concluded that livestock ranches in Tabasco, Mexico, with scattered trees in grazing pastures stored 58.8% more carbon than those grass monocultures, with carbon stocks of 327.01 Mg C ha−1and 134.47 Mg C ha−1, respectively. The results are useful for land management decision making for sustainable livestock systems framed in the Sustainable Development Goals (SDGs).

“…However, consecutive deep tilling was also incongruous in the agricultural system, presumably due to inconsistent yield responses and high execution costs [15,24]. As soil represents the largest carbon pool on earth, and tillage can strongly influence soil CO 2 emissions [25], the selection of suitable tillage practices is of great significance for maintaining soil sustainability and adapting to climate change [26].…”

Soil management practices are important parts of sustainable agriculture. Improving tillage practice is important for alleviating soil degradation and promoting sustainable grain production. A four year field experiment was conducted to examine the effects of deep tillage (DT), incorporated into the minimum tillage (MT), on soil physical properties and crop performance. The field experiments included continuous rotary tillage (RT), continuous DT, and intermittent DT every three years, every two years, and every other year, into RT. The results showed that the introduction of DT into continuous RT reduced the soil bulk density of the 20-30 cm soil layer by 5.6% and reduced nutrient stratification rates by 20–30%, which favored more uniformly distributed soil nutrients in the top soil layer. The root growth for treatments with DT in the deep soil layers (1–1.5 m) was significantly improved, which resulted in a higher soil water depletion. Under deficit irrigation scheduling, the improved root growth and soil water uptake in the deep soil layer improved crop growth and grain production. Overall, a 10.5% increase in yield and 18.3% increase in water productivity were observed when intermittent DT was introduced during the four years. The effects of DT could be maintained for two continuous years. Therefore, it was suggested that after two or three years of RT, DT should be applied to improve soil physical properties and ensure high grain production.

“…Many newly constructed rice paddy fields rely upon groundwater as irrigation water, which can not only cause stress to the over-exploited groundwater resource but also result in salinization and land degradation over the long term due to its high dissolved solid content caused by the high total dissolved solid content in the groundwater in these regions . In Brazil, which has recently turned from a large rice importer to a major rice exporter, rainforest wildfires accelerated in 2019–2020, which may further increase its crop yield and export but also bring significant adverse effects on climate change . As global environmental change may be induced by both geopolitical and trade policies, informed decision making requires life cycle-based approaches to capture both local and global impacts.…”

Agricultural land degradation is posing a serious threat to global food security. Restoration of the degraded land has traditionally been viewed as an inherently sustainable practice; however, restoration processes render consequential environmental impacts which could potentially exceed the benefit of restoration itself. In the present study, an integrated life cycle assessment analysis was conducted to evaluate life cycle primary, secondary, and tertiary impacts associated with the restoration of the contaminated agricultural land. The results demonstrated the importance of including spatially differentiated impacts associated with managing the land and growing crops. Comparing four risk management scenarios at a contaminated field in Southern China, it was found that the primary and secondary impacts followed the order of no action > chemical stabilization > phytoextraction > alternative planting. However, when tertiary impacts were taken into account, alternative planting rendered much higher footprint in comparison with phytoextraction and chemical stabilization, which provides evidence against an emerging notion held by some policy makers. Furthermore, assuming that the loss of the rice paddy field in Southern China is compensated by the deforested land in the Amazon rainforest, the total global environmental impact would far exceed that of no action, resulting in 687 ton CO 2 -e ha −1 of climate change impact. Overall, the present study provides new research findings to support more holistic policy making and also sheds lights on the future development of various restoration technologies.
