“…This study provides new insights into the understanding of pressures to the tropical dry forest, which in our understanding the first time that these elements are studied. However, our estimates may be conservative due to the fact that within this ecosystem dominates slash‐burn‐agriculture and induced grasslands (Corona‐Núñez et al, 2016; Mendoza‐Ponce et al, 2018, 2019). Therefore, it is important to increase the research of the cascade effects derived from fires in tropical dry forests considering the large global coverage of this ecosystem (Miles et al, 2006).…”

Biomass burning, including fires, has been identified as the largest source of primary fine carbonaceous particles in the troposphere and one of the major drivers of global carbon (C) cycle, cloud properties, and climate. Most of the global C emissions happen in the Pantropic region. Modeling estimates suggest an increase in Mexican fire frequencies, intensity, and C emission to the atmosphere. However, no study has combined field and satellite data to estimate C emissions by fires for any tropical country. Here, we present an approach to estimate the spatiotemporal variability of fires and its total C emissions in Mexico with the associated climate that combines national fire inventories with remote sensing. We provide evidence that tropical ecosystems, particularly tropical forests at Yucatan Peninsula, Pacific Coast, and Gulf of Mexico, provide the largest C emissions with high fire densities. We found evidence to contrast the relationships of the interannual and intra-annual variability of C emissions with immediate and lagged climate effects such as El Niño and La Niña events. Data also indicate that C emissions from fires are up to 11 times higher than those from deforestation and account 19% of the total National CO 2 emissions and 5% of the total Pantropical C emissions. Because fires are related to climate change, we encourage future studies to focus on climate fire feedbacks for implementing adequate climate mitigation strategies.

“…Sin embargo, los bosques tropicales presentan una alta tasa de deforestación que los ha reducido a tan sólo un 4.7% del territorio mexicano y las predicciones para el 2080 indican que su extensión disminuirá hasta un 2.5% (Mendoza-Ponce et al, 2019). Esto se debe a malas prácticas de gestión forestal incluyendo mala planeación de la tala y tala ilegal (Hernández-Gómez et al, 2020), así como a cambios en el uso de la tierra para agricultura o ganadería y al crecimiento demográfico (Carrillo et al, 2019).…”

Carbon contents and fine root production in tropical silvopastoral systems

et al. 2020

Owing to the increasing extension of land for livestock production, silvopastoral practices have been among the promising approaches to enhance carbon (C) sequestration. However, the extent of C sequestration in different silvopastoral systems (SPS) and their relationship with fine root production (FRP) is not well understood. The objective of this research was to evaluate the changes in C storage, FRP, and turnover in a part of tropical SPS. We evaluated above‐ and belowground C storage, FRP and turnover in live fences (LF), dispersed tree (DT) silvopasture, and compared these with open pasturelands (OP) in Southeastern Mexico. We applied the stock change approach to calculate biomass growth rates and the ingrowth monolith method for FRP. Biomass stocks in the same plots are re‐measured over time in the stock change approach. Woody biomass stocks differed significantly between SPS (DT: 37.2, LF: 9.8 Mg ha−1) and the accumulation rates in both SPS were significantly higher than zero (0.2–2.2 Mg ha−1 yr−1). Soil organic carbon (SOC) contents were significantly higher in SPS (LF: 2.4%, DT: 3.1%) compared to OP (1.6%). FRP significantly differed between SPS (LF: 27.8, DT: 45.4, and OP: 9.4 g m−2 yr−1) and correlated positively with SOC content. Higher SOC reduced soil compaction in silvopastoral lands as indicated by lower soil bulk density. The results on C stocks change and fine root dynamics contribute to understanding C sequestration potential of tropical SPS, identifying ecologically sound strategies to mitigate greenhouse gases from the livestock sector, and aid restoration of ecosystem services for degraded pasturelands.
