“…For vegetation covering in SH, temperature generally does not affect the growing season as indicated by an average of only 7.5 days of snow cover annually, in contrast to 125 days in the NH, as observed by MODIS [13]. Rather, lower temperatures directly constraints growth whilst higher temperatures directly reduces growth.…”

Background: Environmental issues have gained widespread attention from all around the world and most of them originate from the root cause of climate change. Climate change occurs when there is increased concentrations of greenhouse gases in the environment, reflecting less heat back to space. In view of extreme weather and consequences, afforestation is now seen as one of the most effective methods in mitigating the effects of climate change. Increasing popularity of using forests as mitigation methods, however, does not translate to forests being effective solutions in all situations. Being part of our ecosystem, processes of forests are easily altered by climate change itself. Aims: To ascertain if afforestation can effectively mitigate the effects of climate change in consideration that the processes of trees are affected by climate change itself. Study Design: Literature review. Methods: Data sources include Nature, Science Direct and environmental journals. Results: Climate change currently increases the ability of forests to mitigate climate change but long-term exposure to increased temperatures and carbon dioxide (CO2) levels reduce their abilities to do so. Location of where afforestation is carried out also affects the extent of effectiveness in reducing CO2 levels and climate change. Conclusion: Afforestation can mitigate climate change if implemented appropriately, especially where it is effective. However, the primary solution will still be cutting carbon emissions since trees have a biological limit in response to climate change.

“…Value than was higher that those simulated in this study account by -7 tons CO 2 -eq yr -1 in B1, and -16 tons CO 2 -eq yr -1 in B2. Agricultural systems combine legume forages with grasses, improving animal nutrition and generating co-benefits like improved soil fertility and increased soil and biomass C accumulation (Parra et al 2019). However, belowground C-inputs from exudation and root sloughing from C4 grasses are high in Brachiaria pastures, forming the base for soil organic matter-buildup in these systems (Anderson-Teixeira et al 2016).…”

“…According to Chambers et al (2016), over the lifetime of the cropland soil health conservation practices, it can be expected that NRCS conservation practices sequester approximately 0.07 to 0.96 tons C ha -1 y -1 . It could be verified that the fertilization of pasture, calagem use (Paradelo et al 2015), the use of productive species, conversion of permanent pasture for improved pasture (Parra et al 2019), the presence of legumes in pasture, increases soil C accumulation (Guan et al 2016) and decrease GHG emissions (Naranjo et al 2012). This study confirms that well-managed B2 on livestock system in the tropics can neutralizer soil CO 2 emissions and accumulate soil carbon.…”

“…Technical potential for soil organic carbon (SOC) sequestration at global (Olsen 2013) and US (Swan et al 2015;Sperow 2016) scales, generally support these earlier estimates of a significant soil C sink potential, on the order of hundreds of teragrams (1 Tg equals 1 million metric tonnes) per year in the United States and roughly an order of magnitude higher globally. However, there are very few re-ports of mitigation practices associated to absortion potential of soil CO 2 emissions in pastures in Colombia (Naranjo et al 2012;Parra and Mora-Delgado 2017;Parra et al 2019), and specifically in the area of influence (Silva and Orozco 2018).…”

“…Since then, rates of SOC sequestration through adoption of best management practices have been assessed for diverse land uses and eco-regions, such as the inclusion of cover crops in pastures (Poeplau and Don 2013;Lal 2015), for conversion of extensive pasture for improved pasture (Naranjo et al 2012;Parra et al 2019). Accumulation of SOC in improved pastures also can occur following changes in soil management practices as lime and fertilizer aplication, that either increase the production of residue remaining on the field or decrease the losses of soil organic carbon in the form of carbon dioxide (Lal 2015).…”

Soil carbon sequestration refers to the process of transferring carbon dioxide (CO2) from the atmosphere into the soil. The objective of this research was to do a simulation of how soil management factors in pastures can contribute to mitigate climate change by reducing soil CO2-eq emissions due to increases of soil organic carbon. In livestock systems of Cumaral (Meta), Colombia, IPCC Tier 2 methodology was used to compare changes in soils C stocks under (a) two pasture types: Brachiaria decumbens grass pastures (B1) and Brachiaria decumbens grass pastures associated with Pueraria phaseloides legume (B2); (b) four increasing doses of CaCO3: 0, 1.1, 2.2, 3.3 tons ha-1; (c) three sources of N, P, K fertilizers: 100 kg ha-1 Urea, 200 kg ha-1 Triple Superphosphate and 100 kg ha-1 Potassium Chloride. The statistical design was a randomized complete block design in factorial arrangement 2 x 4 x 3. Tukey test showed that the inclusion of kudzú in B. decumbens pasture (B2), 2.2 and 3.3 tons CaCO3 ha-1 in B1 and B2, and the fertilization of B1 with Urea and B2 with Triple Superphosphate showed a greater benefit in soil C accumulation and CO2-eq emissions neutralization. Adittional cluster analysis showed that B2 liming with higher lime doses regardless of the type of fertilizer used presented major soil C stored grouped in Cluster 1. We concluded that these soil management factors should be feasible to implement in pastures, that can help offset the negative effects of global climate change on livestock systems at tropical zones.

Greenhouse gas balance and mitigation potential of agricultural systems in Colombia: A systematic analysis

Agriculture is widely recognized as a source of considerable greenhouse gas (GHG) emissions, with opportunities for mitigation. The limited capacity to identify and collect reliable activity data and to quantify emissions by sources and removals by sinks needs to be addressed. One proposed solution is to adapt IPCC methodologies that include estimations of both CO2 emissions and carbon sequestration in agricultural systems, which were applied to Colombia at the farm level in this study. The aim of this work was to provide an assessment of GHG balances through these IPCC methodologies to identify potential GHG mitigation in sustainable agricultural systems used in Colombia that provide acceptable GHG trade‐offs to the atmosphere. Agroforestry systems made the largest contribution to this mitigation potential because of the potential to sequester carbon in both soil and biomass, giving a negative GHG emission to the atmosphere. GHG balance analysis at the Colombian farm level indicated that conventional agriculture with pastures of Pennisetum clandestinum in rotation with potatoes (PRP) in the Andean zone of Nariño (Colombia) is a large emitter of GHG with 9.1 ton CO2eq ha−1 year−1. On the other hand, in livestock systems in the Andean zone (Antioquia), intensive silvopastoral systems with 500 Eucalyptus tereticornis trees ha−1 (SSPi) on pastures is a great neutralizer of GHG emissions, accounting for −26.6 t CO2eq ha−1 year−1. Agroforestry systems play a leading role, as crop rotation and improved pastures can represent a GHG mitigation opportunity for sustainable agricultural production at the farm level in Colombia. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.
