“…Numerous studies (López-Santiago et al, 2019;Carvajal and Andrade, 2020;Yunga, 2020), have confirmed that the use of SPS contributes to reducing GHG emissions from livestock farms. Here, we found that this reduction was on the order of 17%, which is a considerable step toward achieving the goals of returning to livestock as a mitigator of climate change (Schettini et al, 2021;Gutiérrez Bermúdez and Mendieta Araica, 2022). Despite this, some slight differences can be noted between states, which can basically be explained by the broad characteristics of SPS, which can vary in the abundance, type and size of perennial woody plants (Villanueva-López et al, 2015;López et al, 2019;Schettini et al, 2021).…”

“…Switching from degraded pastures to any other type of land use system always results in positive benefits for climate change mitigation, because it allows for carbon concentration (Apan et al, 2021). SPS allow such reconversion -that is, from net CO 2 emitting systems, such as degraded pastures, to net carbon-fixing systems -while at the same time increasing production, quality and improving the supply of other ecosystem services (Andrade et al, 2008;López-Santiago et al, 2019;Apan et al, 2021;Schettini et al, 2021).…”

“…Establishing SPS on conventional open pastures increases the capture of carbon in biomass and soils, as well as reducing deforestation and GHG emissions (Andrade et al, 2008;Aryal et al, 2022;Oldfield et al, 2022;Udawatta et al, 2022). Several studies have confirmed the positive effect of SPS in reducing the CF of livestock farms (Schettini et al, 2021;Brook et al, 2022;Parra et al, 2022).…”

Livestock production is one of the most important agricultural sources of greenhouses gasses (GHG). Transforming the livestock sector is a critical task to mitigate the effects of climate change, and the implementation of silvopastoral systems (SPS) may be a way to do so. Carbon footprint (CF) estimation was carried out for 131 conventional livestock farms (CONF) and SPS farms (SPSF) selected in the states of Jalisco, Chiapas and Campeche (Mexico). GHG emissions were estimated based on interviews with the farmers and farm monitoring to collect information about management, milk production and the live weight gain (LWG) of calves (for meat production) using national emission factors. Emissions from animals, fossil fuels, electricity and nitrogen fertilizers were estimated using Tier I and II criteria. Land use distribution was recorded for each farm, and their carbon fixation in total biomass and soils was estimated using studies from tropical Latin America. CF was estimated for area and for production of milk and the LWG of calves. SPSF had lower GHG emissions, higher carbon fixation rates and a better CF than CONF (5.7 vs. 8.0 t CO2e/ha/year; 6.9 vs. 5.5 t C/ha/year and − 5.0 vs. −2.9 t CO2e/ha/year, respectively). The CF of milk production and calf LWG were − 68.6 to −4.6 kg CO2e/kg and − 3.2 to −0.1 t CO2e/kg, respectively. Our results highlight the importance of implementing SPS to mitigate climate change in livestock production, given its contribution to GHG emissions and the importance of capturing atmospheric carbon in biomass and soils. National and regional policies should focus on promoting implementing SPS as an active and effective strategy for improving CF in livestock farms.

“…These advantages contribute significantly to various aspects, including (i) animal welfare improvement: SPS mitigate heat stress and reduce the presence of hematophagous flies, enhancing the well-being of the cattle [ [154] , [155] , [156] , [157] , [158] ], (ii) environmental enhancement: The shade cover of SPS reduces water consumption by the animals and promotes biodiversity [ [159] , [160] , [161] ], and (iii) productivity and quality enhancement: SPS positively influence productivity and quality indicators [ 154 , 159 , 162 ]. This multi-faceted impact highlights SPS's potential to contribute to climate change mitigation by curbing CH 4 emissions [ [110] , [111] , [112] , [113] ]. Additionally, SPS aid in climate adaptation by providing thermal comfort to animals amidst rising temperatures and bolstering feed availability during critical periods [ 158 , 159 , 163 , 164 ].…”

“…In addition to providing environmental benefits, such as the mitigation of GHG emissions [ [110] , [111] , [112] , [113] , [114] ], SPS provide numerous ecosystem services. Several studies [ [48] , [49] , [50] , [51] , 115 ] have documented evidence on the provision of ecosystem services by SPS, such as microclimatic regulation, carbon storage and sequestration, soil conservation, and the creation of habitats for biodiversity.…”

Silvopastoral systems (SPS) are strategic in neutralizing greenhouse gases (GHG) emissions in livestock production systems, particularly in the tropics. This research assessed the mitigation potential of SPS on the carbon footprint (CFP) neutralizing in one integrated livestock farm of cow-calf and pig production system in the Colombian Amazon. Annual carbon accumulation rate (ACAR) in MgCO2e ha−1y−1, was evaluated on living above-ground biomass including trees and shrubs > 2 cm DBH and pasture, and leaf litter and below-ground biomass including coarse and fine roots, soil organic carbon 0–10 cm deep, and total ACAR adding up all components in live fences (LF), scattered trees (ST), fallows (FW), fodder bank (FB) and pastures (PT). The GHG emissions in MgCO2e ha−1y−1 were accounted in CO2 from liming, urea, fuel, electricity, and supplementation, CH4 from enteric methane, manure, and organic fertilization and N2O from urine and manure. The C balance was obtained from the differences between ACAR of SPS on farm and the CFP per surface. Mean total ACAR expressed in MgC ha−1y−1 were 9.0 ± 4.6 in FW, 7.0 ± 1.2 in LF, 5.5 ± 0.8 in ST, 4.2 ± 0.2 in FB and 2.9 ± 0.1 in PT. Mean CFP was 3.7 MgCO2e ha−1y−1, 5.3 MgCO2e Live Weight ha−1y−1, and 23.6 MgCO2e Live Weight Gain y−1. The CFP (area) can be neutralized with total ACAR value of 2.1 ha−1 for LF, 1.6 ha−1 for FW, 2.6 ha−1 for ST, 3.5 ha−1 for FB and 5.1 ha−1 for PT. The Silvopastoral systems have a higher potential for neutralizing GHG emissions than pasture-based scenario when considering the ACAR in above-ground biomass.
