Synergies between global low-carbon development processes and financial fluctuations from 1991–2019: a functional data analysis

Financial fluctuations affect all aspects of economic production and daily life. Using the slacks-based measure (SBM) model and the functional data analysis (FDA) technique, this study examined the pattern of global low-carbon development and the synergies between these development processes and financial fluctuations from 1991–2019. The main results show that (1) the world is making steady progress in low-carbon development. However, there were clear imbalances at the regional level. Among the countries analysed, Italy, Luxembourg, and the United States are leading in low-carbon development, while Ukraine, Bulgaria, and Slovakia are lagging. (2) The direction and magnitude of financial development affecting global low-carbon development vary over time. In recent years, its internal instabilities have increased. (3) There are distinct spatial heterogeneities in the direction and magnitude of this impact. Compared with other regions, Europe and the Asia-Pacific region’s low-carbon development processes are more sensitive to their own financial situation.

Efficacy of Naphthyl Acetic Acid Foliar Spray in Moderating Drought Effects on the Morphological and Physiological Traits of Maize Plants (Zea mays L.).

The threat of varying global climates has greatly driven the attention of scientists, as climate change increases the odds of worsening drought in many parts of Pakistan and the world in the decades ahead. Keeping in view the forthcoming climate change, the present study aimed to evaluate the influence of varying levels of induced drought stress on the physiological mechanism of drought resistance in selected maize cultivars. The sandy loam rhizospheric soil with moisture content 0.43-0.5 g g-1, organic matter (OM) 0.43-0.55 g/kg, N 0.022-0.027 g/kg, P 0.028-0.058 g/kg, and K 0.017-0.042 g/kg was used in the present experiment. The findings showed that a significant drop in the leaf water status, chlorophyll content, and carotenoid content was linked to an increase in sugar, proline, and antioxidant enzyme accumulation at p < 0.05 under induced drought stress, along with an increase in protein content as a dominant response for both cultivars. SVI-I & II, RSR, LAI, LAR, TB, CA, CB, CC, peroxidase (POD), and superoxide dismutase (SOD) content under drought stress were studied for variance analysis in terms of interactions between drought and NAA treatment and were found significant at p < 0.05 after 15 days. It has been found that the exogenous application of NAA alleviated the inhibitory effect of only short-term water stress, but yield loss due to long-term osmotic stress will not be faced employing growth regulators. Climate-smart agriculture is the only approach to reduce the detrimental impact of global fluctuations, such as drought stress, on crop adaptability before they have a significant influence on world crop production.

Investigating the Impact of Global Policy and Political Shifts on Vietnamese Businesses

This paper examines how Vietnamese enterprises in various industries, including oil and gas, transportation, and food, were impacted by the tensions between Russia and Ukraine during the first half of 2022. By utilizing statistical comparison methods, the study found that there were fluctuations in revenue, profit, and other indicators that measure business activity. Specifically, in the oil and gas industry, companies such as Vietnam Gas Corporation, Binh Son Refining and Petrochemical Joint Stock Company, and Ca Mau Petroleum Fertilizer Company saw higher revenue and financial ratios compared to the industry average, while other businesses experienced a decrease from the previous quarter. Transport companies benefited from increased import and export, as well as high freight rates and global price hikes for goods and materials. The food industry in Vietnam saw the Russia-Ukraine conflict as a significant opportunity for growth, but businesses still encountered challenges in capitalizing on this potential. As Vietnam's economy is deeply intertwined with the global economy, fluctuations and high inflation in the world economy can have an impact on the country's economy and businesses. Keywords: Market Volatility, Political Tension, Vietnamese Enterprises, Russia-Ukraine Conflict.

Significance of Short‐Wavelength Magnetic Anomaly Low Along the East Pacific Rise Axis, 9°50′N

AbstractMagnetic anomaly variations near mid‐ocean ridge spreading centers are sensitive to a variety of crustal accretionary processes as well as geomagnetic field variations when the crust forms. We collected near‐bottom vector magnetic anomaly data during a series of 21 autonomous underwater vehicle Sentry dives near 9°50′N on the East Pacific Rise (EPR) covering ∼26 km along‐axis. These data document the 2–3 km wide axial anomaly high that is commonly observed at fast‐spreading ridges but also reveal the presence of a superimposed ∼800 m full wavelength anomaly low. The anomaly low is continuous for ≥13 km along axis and may extend over the entire survey region. A more detailed survey of hydrothermal vents near 9°50.3′N reveals ∼100 m diameter magnetic lows, which are misaligned relative to active vents and therefore cannot explain the continuous axial low. The axial magnetization low persists in magnetic inversions with variable extrusive source thickness, indicating that to the extent to which layer 2A constitutes the sole magnetic source, variations in its thickness alone cannot account for the axial low. Lava accumulation models illustrate that high geomagnetic intensity over the past ∼2.5 kyr, and decreasing intensity over the past ∼900 years, are both consistent with the broad axial anomaly high and the superimposed shorter wavelength low. The continuity of this axial low, and similar features elsewhere on the EPR suggests, that either crustal accretionary processes responsible for this anomaly are common among fast‐spread ridges, or that the observed magnetization low may partially reflect global geomagnetic intensity fluctuations.

Coralline algal and foraminiferal records of the Pliocene paleoclimatic conditions and water-depth changes in the northern South China Sea

Detailed paleontological and sedimentological data from the Pliocene interval of core XK-1 allow for a detailed documentation of the carbonate system in the northern South China Sea (SCS). Six facies are identified. Based on a comprehensive analysis of facies changes, the paleoclimatic conditions and paleowater depths during the Pliocene in the Xisha area in the northern SCS are reconstructed. The changes in the abundance of the algal genus Sporolithon and the planktonic foraminifera species Orbulina universa, Globigerinoides quadrilobatus, Globorotalia menardii, and Globigerinoides obliquus indicate that the climate in the SCS gradually became warmer from 5.3 to 4.3 Ma and then cooled from 4.3 to 2.6 Ma, which was attributed to the changes in atmospheric pCO2. The high abundance of encrusting acervulinids and coralline algae and the low coral abundance suggest periods of elevated nutrient level, possibly linked to increases in nutrient input from the higher latitudes. Distinct changes in coralline algal and foraminiferal facies help the reconstruction of paleowater depths during the Pliocene in the Xisha area. The water depth was generally rising from 5.3 to 4.3 Ma and declining afterward, which was similar to that in the Yinggehai–Qiongdongnan Basin (located on the northern part of the Xisha area). This similarity indicates that there was a common factor controlling the long-term variation in water depth in the northern SCS. The comparison between paleowater depth changes and global eustatic sea-level fluctuations indicates that the regional tectonic subsidence was important from 5.3 to 4.7 Ma. Such subsidence was probably related to thermal subsidence after the magmatism intrusion activity beneath the basement at the initial stage of the Pliocene. This study indicates that the comprehensive analysis of algal and foraminiferal facies has great potential to reconstruct the climatic conditions and water depths in the ancient times.

Ecological shifts and hominin adaptations during the Mid-Pleistocene Climate Transition in Northeast Asia as evidenced by isotopic analysis (δ13C, δ18O) of mammalian enamel from Early Paleolithic sites in the Nihewan Basin, China

The Nihewan Basin in North China is one of the most important early archaeological sequences for our understanding of the ecological ranges exploited by hominins and how their adaptive behaviors were shaped by local, regional, and global environmental fluctuations. This study contributes to the topic by conducting stable isotope (δ13C, δ18O) analyses of mammalian tooth enamel from several Early Pleistocene assemblages in the Nihewan Basin dated to ca. 1.2–1.1 Ma, and exploring the links between hominin behavioral adaptations and ecological changes during the Mid-Pleistocene Climate Transition in Northeast Asia mainland. Our isotopic analysis of bulk samples (n = 215) indicates that the Nihewan Basin regional environment underwent significant changes, from landscapes dominated by wet and closed pure C3 vegetation no later than 1.2 Ma, to those dominated by dry and open C3/C4 mixed vegetation during 1.2–1.1 Ma. Additionally, the isotopic analysis of sequential samples (n = 16) suggests seasonal variations. These isotope results interpreted in the context of hominin behavioral traits indicate that hominins exhibited cognitive and technical flexibility in the face of complex and unstable regional ecological settings, suggesting that they adjusted to the environmental fluctuations characteristic of high-latitude arid/semi-arid regions such as the Nihewan Basin over or prior to the Mid-Pleistocene Climate Transition.

Rapid cold sterilization of 3D printed surgical instruments for the austere environment

IntroductionMedical operations are vulnerable to global supply chain fluctuations. The ability to locally produce and reliably sterilize medical equipment may mitigate this risk. This project developed a reliable high-level disinfection process for 3D printed surgical tools. MethodsSurgical instruments and consumables were designed and printed from various materials. Devices contaminated with known and unknown bacteria underwent one of three cleaning methods followed by high-level disinfection using submersion in a Cidex OPA Solution. Devices were then cultured on blood agar plates and incubated for 48 h. Positive and negative controls were performed. ResultsThe results of control experiments showed no growth on negative controls and significant growth on all positive control plates. Of the three cleaning methods tested, one showed no growth: cleaning with isopropyl alcohol and chlorhexidine followed by Cidex bath. DiscussionThis project successfully developed a rapid high-level disinfection process for 3D printed surgical instruments made from two different types of 3D printing material.

Fluvial entrenchment of the Gonghe Basin and integration of the upper Yellow River - Evidence from the cosmogenically dated geomorphic surfaces

The geomorphic evolution of the Yellow River, especially its upper reach, contains critical information on the tectonic activity and climatic change within and around the northeastern Tibetan Plateau, and even matters in understanding the effects of regional disaster chain. However, the integration history of the upper Yellow River and its related connections with drainage reaches inside and outside the Tibetan Plateau remain indistinct. The main controversy lies in the excavation times of some upper-reach basin systems. The Gonghe Basin, located within the northeastern Tibetan Plateau, has long been considered one of the most pivotal areas providing insights into the evolution of the upper Yellow River. In this study, we report two cosmogenic burial ages regarding the abandonment of the geomorphic surfaces within the Gonghe Basin. The two selected geomorphic surfaces are the abandoned connecting pass between Gonghe and Guide Basins (i.e., the Gahaitan channel), and the topmost Yellow River terrace in the Gonghe Basin known as the Third Tala surface. Our results show that the Gahaitan channel and the Third Tala surface were abandoned at 1.17 ± 0.10 Ma and 0.76 ± 0.12 Ma respectively, denoting its excavation by the incision of the Yellow River in the late Early Pleistocene period. Our analysis takes into account regional fault activities, landscape adjustment, and global climate fluctuations, indicating that the excavation was jointly influenced by regional fault activities and the glacial-interglacial cyclicity during the Mid-Pleistocene Transition. When integrated with evidence from river terraces in upstream and downstream regions, our results indicate that the integration of the upper Yellow River behaves a roughly headward erosion pattern from the Plateau margin, while the integration process appears to be heterogeneous. At last, the integration history of the upper Yellow River was further explored.

An Adaptive Hybrid Sampling Method for Free-Form Surfaces Based on Geodesic Distance

High precision geometric measurement of free-form surfaces has become the key to high-performance manufacturing in the manufacturing industry. By designing a reasonable sampling plan, the economic measurement of free-form surfaces can be realized. This paper proposes an adaptive hybrid sampling method for free-form surfaces based on geodesic distance. The free-form surfaces are divided into segments, and the sum of the geodesic distance of each surface segment is taken as the global fluctuation index of free-form surfaces. The number and location of the sampling points for each free-form surface segment are reasonably distributed. Compared with the common methods, this method can significantly reduce the reconstruction error under the same sampling points. This method overcomes the shortcomings of the current commonly used method of taking curvature as the local fluctuation index of free-form surfaces, and provides a new perspective for the adaptive sampling of free-form surfaces.

Using in silico perturbational approach to identify critical areas in schizophrenia.

Schizophrenia is a debilitating neuropsychiatric disorder whose underlying correlates remain unclear despite decades of neuroimaging investigation. One contentious topic concerns the role of global signal (GS) fluctuations and how they affect more focal functional changes. Moreover, it has been difficult to pinpoint causal mechanisms of circuit disruption. Here, we analyzed resting-state fMRI data from 47 schizophrenia patients and 118 age-matched healthy controls and used dynamical analyses to investigate how global fluctuations and other functional metastable states are affected by this disorder. We found that brain dynamics in the schizophrenia group were characterized by an increased probability of globally coherent states and reduced recurrence of a substate dominated by coupled activity in the default mode and limbic networks. We then used the in silico perturbation of a whole-brain model to identify critical areas involved in the disease. Perturbing a set of temporo-parietal sensory and associative areas in a model of the healthy brain reproduced global pathological dynamics. Healthy brain dynamics were instead restored by perturbing a set of medial fronto-temporal and cingulate regions in the model of pathology. These results highlight the relevance of GS alterations in schizophrenia and identify a set of vulnerable areas involved in determining a shift in brain state.

Limit shape for infinite rank limit of tensor power decomposition for Lie algebras of series *

We consider the Plancherel measure on irreducible components of tensor powers of the spinor representation of . The irreducible representations correspond to the generalized Young diagrams. With respect to this measure the probability of an irreducible representation is the product of its multiplicity and dimension, divided by the total dimension of the tensor product. We study the limit shape of the generalized Young diagram when the tensor power N and the rank n of the algebra tend to infinity with fixed. We derive an explicit formula for the limit shape and prove convergence to it in probability. We prove central limit theorem for global fluctuations around the limit shape.

An anatomy of external shocks in the Andean region

This paper applies an agnostic SVAR approach to study the response of four Andean economies (Bolivia, Colombia, Ecuador, and Peru) to international shocks. More specifically, we look at the response of GDP, the real exchange rate, fiscal and external balances, and inflation to global demand, commodity price, monetary and financial shocks. Our results confirm that the Andean region is highly exposed to changes in external conditions, and especially to global demand fluctuations associated with declines in commodity prices. However, despite the similarities that characterize these countries in terms of their income level or their productive specialization, we find substantial heterogeneity in the effects of the shocks, which we attribute to differences in the shock absorbing capacity of their macroeconomic frameworks. This result underlies the need to put in place external buffers to fully exploit the benefits of a greater presence in international markets, be it in the form of exchange rate flexibility, international reserves, or fiscal and monetary space to act countercyclically.

The spatial-temporal dynamics of pulmonary blood flow are altered in pulmonary arterial hypertension.

Global fluctuation dispersion (FDglobal), a spatial-temporal metric derived from serial images of the pulmonary perfusion obtained with MRI-arterial spin labeling, describes temporal fluctuations in the spatial distribution of perfusion. In healthy subjects, FDglobal is increased by hyperoxia, hypoxia, and inhaled nitric oxide. We evaluated patients with pulmonary arterial hypertension (PAH, 4F, aged 47 ± 15, mean pulmonary artery pressure 48 ± 7 mmHg) and healthy controls (CON, 7F, aged 47 ± 12) to test the hypothesis that FDglobal is increased in PAH. Images were acquired at ∼4-5 s intervals during voluntary respiratory gating, inspected for quality, registered using a deformable registration algorithm, and normalized. Spatial relative dispersion (RD = SD/mean) and the percent of the lung image with no measurable perfusion signal (%NMP) were also assessed. FDglobal was significantly increased in PAH (PAH = 0.40 ± 0.17, CON = 0.17 ± 0.02, P = 0.006, a 135% increase) with no overlap in values between the two groups, consistent with altered vascular regulation. Both spatial RD and %NMP were also markedly greater in PAH vs. CON (PAH RD = 1.46 ± 0.24, CON = 0.90 ± 0.10, P = 0.0004; PAH NMP = 13.4 ± 6.1%; CON = 2.3 ± 1.4%, P = 0.001 respectively) consistent with vascular remodeling resulting in poorly perfused regions of lung and increased spatial heterogeneity. The difference in FDglobal between normal subjects and patients with PAH in this small cohort suggests that spatial-temporal imaging of perfusion may be useful in the evaluation of patients with PAH. Since this MR imaging technique uses no injected contrast agents and has no ionizing radiation it may be suitable for use in diverse patient populations.NEW & NOTEWORTHY Using proton MRI-arterial spin labeling to obtain serial images of pulmonary perfusion, we show that global fluctuation dispersion (FDglobal), a metric of temporal fluctuations in the spatial distribution of perfusion, was significantly increased in female patients with pulmonary arterial hypertension (PAH) compared with healthy controls. This potentially indicates pulmonary vascular dysregulation. Dynamic measures using proton MRI may provide new tools for evaluating individuals at risk of PAH or for monitoring therapy in patients with PAH.

Functional Connectivity Mapping for rTMS Target Selection in Depression.

Repetitive transcranial magnetic stimulation (rTMS) protocols increasingly use subgenual anterior cingulate cortex (sgACC) functional connectivity to individualize treatment targets. However, the efficacy of this approach is unclear, with conflicting findings and varying effect sizes across studies. Here, the authors investigated the effect of the stimulation site's functional connectivity with the sgACC (sgACC-StimFC) on treatment outcome to rTMS in 295 patients with major depression. The reliability and accuracy of estimating sgACC functional connectivity were validated with data from individuals who underwent extensive functional MRI testing. Electric field modeling was used to analyze associations between sgACC-StimFC and clinical improvement using standardized assessments and to evaluate sources of heterogeneity. An imputation-based method provided reliable and accurate sgACC functional connectivity estimates. Treatment responses weakly but robustly correlated with sgACC-StimFC (r=-0.16), but only when the stimulated cortex was identified using electric field modeling. Surprisingly, this association was driven by patients with strong global signal fluctuations stemming from a specific periodic respiratory pattern (r=-0.49). Functional connectivity between the sgACC and the stimulated cortex was correlated with individual differences in treatment outcomes, but the association was weaker than those observed in previous studies and was accentuated in a subgroup of patients with distinct, respiration-related signal patterns in their scans. These findings indicate that in a large representative sample of patients with major depressive disorder, individual differences in sgACC-StimFC explained only ∼3% of the variance in outcomes, which may limit the utility of existing sgACC-based targeting protocols. However, these data also provide strong evidence for a true-albeit small-effect and highlight opportunities for incorporating additional functional connectivity measures to generate models of rTMS response with enhanced predictive power.

Reconstruction of Lake-Level Changes by Sedimentary Noise Modeling (Dongying Depression, Late Eocene, East China)

The late Eocene succession of the Dongying Depression forms a highly productive hydrocarbon source. However, due to lack of an unambiguous fine chronostratigraphic framework for the late Eocene stratigraphy, it is challenging to understand the paleolake’s evolution and the driven mechanism of lake-level variation, a limitation which hinders hydrocarbon exploration. In this work, high-resolution gamma-ray logging data were analyzed to carry out the cyclostratigraphic analysis of the third member (Es3) of the Shahejie Formation in the Dongying Depression. Significant 405-kyr eccentricity cycles were recognized based on time series analysis and statistical modeling of estimated sedimentation rates. We abstracted ~57 m cycles of the GR data in the Es3 member, which were comparable with the long eccentricity cycles (~405-kyr) of the La2004 astronomical solution, yielding a 6.43 Myr long astronomical time scale (ATS) for the whole Es3 member. The calibrated astronomical age of the third/fourth member of the Shahejie Formation boundary (41.21 Ma) was adopted as an anchor point for tuning our astrochronology, which provided an absolute ATS ranging from 34.78 ± 0.42 Ma to 41.21 ± 0.42 Ma in Es3. According to the ATS, sedimentary noise modeling for the reconstruction of lake-level changes was performed through the late Eocene Es3. The lake-level changes obtained based on sedimentary noise modeling and spectrum analysis reveal significant ~1.2 Myr cycles consistent with global sea level variations which were related to astronomical forcing. Potential driven mechanisms of marine incursion and/or groundwater table modulation were linked to explain the co-variation of global sea level changes and regional lake level changes. Our results suggest global sea level fluctuations may have played an important role in driving the hydroclimate and paleolake evolution of the late Eocene Dongying Depression.

PENENTUAN NILAI PREMI ASURANSI PERTANIAN BERBASIS HARGA INTERNASIONAL MENGGUNAKAN MODEL MEAN REVERSION DENGAN MUSIMAN

The seasonal cycle causes cocoa price movements in the international market to fluctuate. This certainly affects the development of cocoa prices at the producer level, causing uncertainty about the prices received by farmers. International price-based agricultural insurance is an alternative to protect farmers against global price fluctuations. Compensation is given if the global price of cocoa falls below the agreed trigger value. This study aims to calculate the fair premium value for agricultural insurance based on international prices for cocoa in the Tabanan Regency, Bali, which was simulated using a mean reversion model with seasonality. To perform the simulation, the first step is to estimate the parameters of the seasonal model and the mean reversion model. Next, simulate the international price of cocoa. Then, determine the trigger value based on the percentile of the simulation data. Finally, calculate the premium value using the cash-or-nothing put option with the Black-Scholes model. The results show that the premium value which is considered fair lies between 5,77% to 11,08% of the insured value.

Proline-Proline Dyad in the Fusion Peptide of the Murine β-Coronavirus Spike Protein's S2 Domain Modulates Its Neuroglial Tropism.

The β-Coronavirus mouse hepatitis virus (MHV-A59)-RSA59 has a patent stretch of fusion peptide (FP) containing two consecutive central prolines (PP) in the S2 domain of the Spike protein. Our previous studies compared the PP-containing fusogenic-demyelinating strain RSA59(PP) to its one proline-deleted mutant strain RSA59(P) and one proline-containing non-fusogenic non-demyelinating parental strain RSMHV2(P) to its one proline inserted mutant strain RSMHV2(PP). These studies highlighted the crucial role of PP in fusogenicity, hepato-neuropathogenesis, and demyelination. Computational studies combined with biophysical data indicate that PP at the center of the FP provides local rigidity while imparting global fluctuation to the Spike protein that enhances the fusogenic properties of RSA59(PP) and RSMHV2(PP). To elaborate on the understanding of the role of PP in the FP of MHV, the differential neuroglial tropism of the PP and P mutant strains was investigated. Comparative studies demonstrated that PP significantly enhances the viral tropism for neurons, microglia, and oligodendrocytes. PP, however, is not essential for viral tropism for either astroglial or oligodendroglial precursors or the infection of meningeal fibroblasts in the blood-brain and blood-CSF barriers. PP in the fusion domain is critical for promoting gliopathy, making it a potential region for designing antivirals for neuro-COVID therapy.

Research on spillover effect of foreign market risk on Chinese capital market from perspective of full financial opening-up

ABSTRACT Starting from document research, this paper analyzes the mechanism of the risk spillover effect from developed capital markets to the Chinese capital market. After that, this paper conducts an empirical study on the risk spillover effect of developed capital markets on the Chinese capital market by using the DCC-GARCH model. Then the impact degree of global major stock market fluctuations on the Chinese stock market is measured. The analysis shows that there exists a significant risk spillover effect of developed capital markets on the Chinese capital market, but the effect began to weaken after the financial crisis and the size of the spillover effect can be affected by macro factors such as geographical locations, foreign trade, and foreign investment.

Perspectives on agroecological transition: the case of Guachetá municipality, Colombia

ABSTRACT Specialization of agriculture in the Colombian Andes has increased smallholder vulnerability to climate change and global price fluctuations and has also affected the socio-economic and environmental conditions. Promoting sustainable agriculture in the region requires a holistic understanding of complex agroecosystems. This study identifies and analyzes the main challenges for agriculture and possibilities for agroecological transition of small-scale farms in Guachetá, Colombia. Using the Tool for Agroecology Performance Evaluation (TAPE), 10 elements of agroecology and core performance criteria were evaluated on seven farms. Several key actors were then interviewed, to triangulate data and understand current challenges and possible future pathways. It was found that drier climate and variations in rainfall patterns pose major challenges to current production systems. Limited possibilities for participation in land governance, lack of interest in agriculture among young people, and lack of access to markets hinder the development of sustainable agriculture. Current specialized practices in dairy and potato production are associated with reduced agricultural biodiversity and dependency on agrochemicals, leading to weak synergies and low profitability within agroecosystems. Implementation of agroecological principles and practices such as crop and income diversification and promoting joint action in agricultural development could help overcome sustainability issues in Guachetá.

Oil Palm Plantation: Carbon Sequestration Potential and Effective carbon Management within Serchhip, Mizoram, India

Sustainable management of crop plantations to sequester more carbon is a timely strategy to reduce greenhouse gases, as these have been considered to be potent measures for mitigation of climate change. Oil palm (Elaeis guineensis) is a proven carbon-sequestering perennial crop by biological means, aiding in the mitigation of global warming and climatic fluctuations. The present study was carried out in Serchhip, Mizoram, India from 5th February to 30th March 2021. All major palm plantation sites located within Serchhip were determined in the study. The carbon store was determined from sample plants of three, six, eight, and ten years. This research adopts a destructive approach to estimate the amount of carbon storage. The investigator surveyed the number of trees and the age of the palm trees with the help of farmers. The results indicates that the trunk stores the largest amount of carbon when compared with other plant parts. However, in a three-year plantation, the fronds store more carbon than the trunk. The study reveals that the amount of carbon sequestered by four, six, eight, and ten-year palm trees were 0.045 t, 0.098 t, 0.276 t and 0.539 t respectively. The total sample surveyed was 1015 standing trees from eight locations, and the carbon stock potential accounting all plantations site within Serchhip was estimated to be 345.1 t/yr. Recently, many farmers are planning of giving up oil palm farming and are likely to replace their oil palm fields with other crops. Uprooting, slashing, and burning is the common practice adopted to clear palm trees, which is believed detrimentally to emit tonnes of carbon into the atmosphere. Therefore, the study will be very helpful in decision-making and, consequently selecting a wiser choice for climate change mitigation within Serchhip and, to a larger extent, Mizoram.
