“…It is estimated that pasture lands account for around 3.87 Pg C in 1.89 billion ha, contributing significantly to mitigating the effects of climate change [1]. Moreover, it provides economic benefits to low-income rural and peri-urban populations [3,5], and the potential related to timber sales, improving soil productive yields, ensuring access to food security in a climatically changing future and reducing deforestation rates [6,7].…”

Silvopastoral system (SPS) has been considered as a sustainable management system contribute to greenhouse gas (GHG) reduction, among other benefits compared with open pasture. However, little research has been conducted on the soil and tree biomass carbon stored in traditional pasture with dispersed trees (PWT) compared with pasture in monoculture (PM). The present study was conducted in the Ecuadorian Amazon Region (EAR), along an elevational gradient from 400 to 2000 masl., within the buffer and transition zone of the Sumaco Biosphere Reserve (SBR), using 71 temporary circular plots of 2826 m2, where 26 plots were stablished in PWT and 45 plots in PM. The main results in PWT show significant differences (p ≤ 0.01) between aboveground carbon biomass (AGCtrees) from 41.1 (lowlands), 26.5 (Middle hills) and 16.7 (high mountains) Mg ha−1 respectively, with an average of 31.0 Mg ha−1 in the whole study area. The total carbon pool along the altitudinal gradient in five components: (AGCtrees), belowground carbon (BGCtrees), pasture carbon (AGClitter+pasture) and carbon in soil components (0–10 and 10–30 cm) for PWT ranged from 112.80 (lowlands) to 91.34 (high mountains) Mg ha−1; while for the PM systems assessing three components (AGClitter+pasture) and carbon in soil components (0–10 and 10–30 cm) ranged from 52.5 (lowlands) to 77.8 (middle zone) Mg ha−1. Finally, the paper shows the main dominant tree species in pasture systems that contribute to carbon storage along elevational gradient and concludes with recommendations for decision-making aimed at improving cattle ranching systems through a silvopastoral approach to mitigate the effects of climate change.

“…In Europe, Spain leads scientific production in this field, contributing publications focused on the promotion of silvopastoral policies in European Mediterranean areas [75]. The potential of trees and the climate to regulate soil carbon balance was also evaluated [76]. The proper management of high-quality wood plantations in silvopastoral systems [77] and the establishment of silvopastoral systems in abandoned agricultural lands in northwest Spain [78] were also among the themes of interest.…”

Scientific studies on silvopastoral systems have led to permanent changes oriented toward better silvopasture practices, as well as to policy strategies to respond effectively to the global objectives of restoration and sustainable development. In this work, we performed a bibliometric analysis with the purpose of identifying changes associated with different silvopastoral systems. We applied Bibliometrix in R to analyze 5708 documents published between 1983 and 2022 by including the terms “silvopastoral” and “silvopasture”, among others. The results showed a longitudinal and exponential increase in silvopasture studies over the last 20 years. We adjusted the growth to an S-Curve function with an R2 of 96.06%. The interest of researchers regarding knowledge about silvopasture has evolved; initially, it focused on the characterization of silvopasture, whereas recently, it has focused on the search for strategies to improve the sustainable use of silvopasture, including ecosystem restoration and the implementation of better practices. The following countries stand out as those with the largest scientific production of studies on silvopasture: The United States, Brazil, Mexico, Colombia, and Argentina in the Americas; China and India in Asia; and Spain; and Germany, and the United Kingdom in Europe. In the case of Ecuador, cited leaders in silvopasture facilitated the construction of a group of experts who contribute to the development of public policies. The most cited publications appeared in journals published by the Springer group, Elsevier, and MDPI Journals, mostly in open-access systems. In the future, the disruptive contribution of open-access systems in the global dissemination of knowledge, breaking through the economic constraints of countries, universities, and researchers, should be evaluated.

“…In this context, Pinus radiata D. Don (P. radiata) is an exotic conifer widely used in afforestation and reforestation in Spain, especially in the north, mainly due to its fast growth rate compared with other autochthonous tree species (Crecente-Campo et al, 2009). P. radiata is also one of the most widely used tree species in the establishment of silvopastoral systems (combining woody vegetation with forage and animal production) in regions such as Galicia (NW Spain) (Mosquera-Losada et al, 2015;Ferreiro-Domínguez et al, 2022b). In this region, P. radiata occupies an area of 96.177 ha according to the IV National Forest Inventory, around 7% of the total wooded area (Iv National Forest Inventory [NFI], 2011).…”

Modeling Pinus radiata D. Don growth and pasture production under different land uses and climate scenarios

Yield-SAFE is a biophysical model to predict long-term production according to light and water availability in agricultural, forest, and agroforestry systems. The Yield-SAFE model should be calibrated and validated for the highest number of tree species and crops to be used as a management tool that takes into account climate change. This study aimed to calibrate and validate the Yield-SAFE model for Pinus radiata D. Don and sown pasture (Dactylis glomerata L.) to estimate the production in (1) forest systems, (2) agricultural systems, and (3) silvopastoral systems established in Galicia (NW Spain) under different conditions of climate: (i) reference “current” climate from 1961 to 1990, (ii) climate from 2021 to 2050, and (iii) climate from 2051 to 2080. The Yield-SAFE model can now be used to assess the long-term productivity of P. radiata D. Don and D. glomerata L. under different land uses and climate conditions. The Yield-SAFE model simulated similar tree and pasture growth in all scenarios of climate because the inter-annual variation of climate was small. However, tree growth estimated with the Yield-SAFE model was higher in the silvopastoral systems than in the forest systems, indicating that land use had more impact on land productivity than climate. Therefore, in regions such as Galicia, the Yield-SAFE model could be used as a tool to support the land use change in an agroforestry context, whilst also including climate scenarios which is considered a valuable solution to mitigate the effect of climate change.
