Abstract. The majority of new particle formation (NPF) events
observed in Hada Al Sham, western Saudi Arabia, during 2013–2015 showed an
unusual progression where the diameter of a newly formed particle mode
clearly started to decrease after the growth phase. Many previous studies
refer to this phenomenon as aerosol shrinkage. We will opt to use the term
decreasing mode diameter (DMD) event, as shrinkage bears the connotation of
reduction in the sizes of individual particles, which does not have to be
the case. While several previous studies speculate that ambient DMD events
are caused by evaporation of semivolatile species, no concrete evidence has
been provided, partly due to the rarity of the DMD events. The frequent
occurrence and large number of DMD events in our observations allow us to
perform statistically significant comparisons between the DMD and the
typical NPF events that undergo continuous growth. In our analysis, we find
no clear connection between DMD events and factors that might trigger
particle evaporation at the measurement site. Instead, examination of air
mass source areas and the horizontal distribution of anthropogenic emissions
in the study region leads us to believe that the observed DMD events could
be caused by advection of smaller, less-grown particles to the measurement
site after the more-grown ones. Using a Lagrangian single-particle growth
model, we confirm that the observed particle size development, including the
DMD events, can be reproduced by non-volatile condensation and thus without
evaporation. In fact, when considering increasing contributions from a
semivolatile compound, we find deteriorating agreement between the
measurements and the model. Based on these results, it seems unlikely that
evaporation of semivolatile compounds would play a significant role in the
DMD events at our measurement site. In the proposed non-volatile
explanation, the DMD events are a result of the observed particles having
spent an increasing fraction of their lifetime in a lower-growth environment, mainly enabled by the lower precursor vapor concentrations
further away from the measurement site combined with decreasing
photochemical production of condensable vapors in the afternoon. Correct
identification of the cause of the DMD events is important as the fate and
the climate relevance of the newly formed particles heavily depend on it
– if the particles evaporated, their net contribution to larger and
climatically active particle sizes would be greatly reduced. Our findings
highlight the importance of considering transport-related effects in NPF
event analysis, which is an often overlooked factor in such studies.

Published: August 2023

Abstract. Black carbon (BC; i.e. soot) absorbs radiation and contributes to glacier retreat over the Tibetan Plateau (TP). A lack of comprehensive understanding of the actual mixing state leads to large controversies in the climatic simulation of soot over the TP. In this study, ground-based sampling, electron microscopy analyses, and theoretical calculations were used to investigate the interactions among the liquid–liquid phase separation (LLPS), soot redistribution in secondary particles, and fractal dimension (Df) of soot particles on the eastern rim of the TP. We found that more than half of the total analysed particles were soot-containing particles. One-third of soot-containing particles showed a core shell structure that probably formed the LLPS phenomenon after long-range transport. Particle size and the ratio of organic coating thickness to soot size are two of the major possible factors that likely induce soot redistribution between organic matter and inorganic aerosols in individual particles. The Df sequence is ranked as externally mixed soot (1.79±0.09)< sulfate-coated soot (1.84±0.07)< organic-coated soot (1.95±0.06). We concluded that the soot redistribution process promoted the morphological compaction of soot particles. This study indicates that soot-containing particles experienced consistent ageing processes that induced a more compact morphology and soot redistribution in the LLPS particles on the remote eastern rim of the TP. Understanding the microscopic changes in aged soot particles could further improve the current climate models and evaluations of BC's radiative impacts on the eastern TP and similar remote air.
The impact of Aeolus winds on near-surface wind forecasts over tropical ocean and high-latitude regions
Authors: Zuo Haichen , Hasager Charlotte Bay
Published: August 2023

Abstract. To detect global wind profiles and improve numerical weather prediction (NWP), the European Space Agency (ESA) launched the Aeolus satellite carrying a spaceborne Doppler wind lidar in 2018. After the successful launch, the European Centre for Medium-Range Weather Forecasts (ECMWF) performed the observing system experiments (OSEs) to evaluate the contribution of Aeolus data to NWP. This study aims to assess the impact of Aeolus wind assimilation in the ECMWF model on near-surface (10 m height) wind forecasts over tropical ocean regions by taking buoy measurements for reference and over high-latitude regions by taking weather station data for reference for the year 2020. The assessments were conducted mainly through inter-comparison analysis. The results show that Aeolus data assimilation has a limited impact on sea surface wind forecasts for tropical regions when compared with buoy measurements. For the high-latitude regions in the Northern Hemisphere, Aeolus is able to improve near-surface wind forecasts. This positive impact is more evident as the forecast time step is extended, during the first half year of 2020 and during the winter months. In addition, the v component tends to benefit more from the Aeolus observations than the u component. For the Southern Hemisphere, a few error reductions are observed but exist randomly. Overall, this in situ data-based assessment expands our understanding of the role of Aeolus data assimilation with the global NWP model in predicting near-surface wind for tropical oceans and high-latitude regions.
A Comparison of South Pacific Antarctic Sea Ice and Atmospheric Circulation Reconstructions Since 1900
Authors: Fogt Ryan , Dalaiden Quentin , O'Connor Gemma
Published: August 2023

Abstract. The recent changes and record minima in Antarctic sea ice extent implore the need for longer estimates beyond the short satellite observation period commencing near 1979. However, Antarctic sea ice extent reconstructions based on paleo records and those generated based on instrumental observations from the Southern Hemisphere midlatitudes are markedly different, especially prior to 1979. Here, these reconstructions are examined with the goal of understanding the relative strengths and limitations of each reconstruction better so that researchers using the various datasets can interpret them appropriately. Overall, it is found that the different spatial and temporal resolutions of each dataset play a secondary role to the inherent connections each reconstruction has with its underlying atmospheric circulation. Several Southern Hemisphere pressure reconstructions spanning the 20th century are thus examined further. There are different variability and trends poleward of 60° S between paleo-based and station-based 20th century pressure reconstructions which are connected to the disagreement between the Antarctic sea ice extent reconstructions examined here. Importantly, sensitivity experiments based on only coral paleoclimatological records provide the best agreement between the early pressure reconstructions, suggesting a contributing role of tropical variability is present in the station-based pressure (and therefore sea ice) reconstructions, while high latitude ice core information strongly constrains paleo-based reconstructions (of both pressure and sea ice) near the Antarctic continent. Our results reveal the greatest consistencies and inconsistencies in available datasets and highlight the need to better understand the relative roles of the tropics versus high latitudes in historical sea ice variability around Antarctica.
Evidence of extension at the southwest continental margin of India and opening of the Laccadive Basin: Constraints from geophysical data
Authors: Gilbert Mathews George , Unnikrishnan Parakkal , Radhakrishna Munukutla
Published: August 2023

Abstract. Previous geophysical investigations of the Western Continental Margin of India (WCMI) confirm the double breakup history of the margin with the first breakup taking place between India and Madagascar in Late Cretaceous, and the second breakup event in early Paleocene with Seychelles separation from India. Despite numerous geoscientific studies along the WCMI, the southern part of the margin, which is known to be the conjugate segment of the Madagascar, has been least studied. In this study, we evaluate the multi-channel seismic reflection and gravity anomalies at the margin to identify the early rift signatures in conjunction with the magnetic anomaly identifications in the Mascarene Basin. The analysis led to the identification of two extensional directions, a ENE-WSW oriented extension over the Laccadive Ridge north of Tellicherry Arch, and the NW-SE extension in the Laccadive Basin region towards south. Plate reconstruction models of the Mascarene Basin suggest the ENE-WSW extension observed over the Laccadive Ridge could be related to the India-Madagascar separation. However, the sediment deposition pattern and the presence of Paleocene trap associated with the NW-SE extensional grabens observed in the Laccadive Basin region has been attributed to the post-breakup extension between the Laccadive Ridge and the West coast of India. We further propose that the anti-clockwise rotation of India and the passage of the Reunion plume have facilitated the opening of the Laccadive Basin.

Abstract. Stratospheric aerosols play important roles in Earth’s radiative budget and in heterogeneous chemistry. Volcanic eruptions modulate the stratospheric aerosol layer by injecting particles and particle precursors like sulfur dioxide (SO2) into the stratosphere. Beginning on April 9th, 2021, La Soufrière erupted injecting SO2 into the tropical upper troposphere and lower stratosphere, yielding a peak SO2 loading of 0.3–0.4 Tg. The resulting volcanic aerosol plumes dispersed predominately over the northern hemisphere (NH), as indicated by the CALIOP/CALIPSO satellite observations and model simulations. From June to August 2021 and May to July 2022, the NASA ER-2 high-altitude aircraft extensively sampled the stratospheric aerosol layer over the continental United States during the Dynamics and Chemistry of the Summer Stratosphere (DCOTSS) mission. These in situ aerosol measurements provide detailed insights into the number concentration, size distribution, and spatiotemporal variations of particles within volcanic plumes. Notably, aerosol surface area density and number density in 2021 were enhanced by a factor of 2–4 between 380–500 K potential temperature compared to the 2022 DCOTSS observations, which were minimally influenced by volcanic activity. Within the volcanic plume, the observed aerosol number density exhibited significant meridional and zonal variations while the mode and shape of aerosol size distributions did not vary. The La Soufrière eruption led to an increase in the number concentration of small particles (<400 nm), resulting in a smaller aerosol effective diameter during the summer of 2021 compared to the baseline conditions in the summer of 2022, as observed in regular ER-2 profiles over Salina, Kansas. A similar reduction in aerosol effective diameter was not observed in ER-2 profiles over Palmdale, California, possibly due to the already smaller values in that region during the limited sampling period in 2022. The La Soufrière eruption was modeled with the SOCOL-AERv2 aerosol-chemistry-climate model. The modeled aerosol enhancement aligned well with DCOTSS observations, although the direct comparison was complicated by issues related to the model’s background aerosol burden. This study indicates that the La Soufrière eruption contributed at most 0.6 % to Arctic and Antarctic ozone column depletion in both 2021 and 2022, which is well within the range of natural variability. The modeled top-of-atmosphere one-year global average radiative forcing was -0.08 W/m2 clear-sky and -0.04 W/m2 all-sky. The radiative effects were concentrated in the tropics and NH midlatitudes and diminished to near-baseline levels after one year.
Validating the Nernst–Planck transport model under reaction-driven flow conditions using RetroPy v1.0

Published: August 2023

Abstract. Reactive transport processes in natural environments often involve many ionic species. The diffusivities of ionic species vary. Since assigning different diffusivities in the advection–diffusion equation leads to charge imbalance, a single diffusivity is usually used for all species. In this work, we apply the Nernst–Planck equation, which resolves unequal diffusivities of the species in an electroneutral manner, to model reactive transport. To demonstrate the advantages of the Nernst–Planck model, we compare the simulation results of transport under reaction-driven flow conditions using the Nernst–Planck model with those of the commonly used single-diffusivity model. All simulations are also compared to well-defined experiments on the scale of centimeters. Our results show that the Nernst–Planck model is valid and particularly relevant for modeling reactive transport processes with an intricate interplay among diffusion, reaction, electromigration, and density-driven convection.
CHEEREIO 1.0: a versatile and user-friendly ensemble-based chemical data assimilation and emissions inversion platform for the GEOS-Chem chemical transport model

Published: August 2023

Abstract. We present a versatile, powerful, and user-friendly chemical data assimilation toolkit for simultaneously optimizing emissions and concentrations of
chemical species based on atmospheric observations from satellites or suborbital platforms. The CHemistry and Emissions REanalysis Interface with
Observations (CHEEREIO) exploits the GEOS-Chem chemical transport model and a localized ensemble transform Kalman filter algorithm (LETKF) to
determine the Bayesian optimal (posterior) emissions and/or concentrations of a set of species based on observations and prior information using an
easy-to-modify configuration file with minimal changes to the GEOS-Chem or LETKF code base. The LETKF algorithm readily allows for nonlinear
chemistry and produces flow-dependent posterior error covariances from the ensemble simulation spread. The object-oriented Python-based design of
CHEEREIO allows users to easily add new observation operators such as for satellites. CHEEREIO takes advantage of the Harmonized Emissions Component (HEMCO) modular structure of
input data management in GEOS-Chem to update emissions from the assimilation process independently from the GEOS-Chem code. It can seamlessly
support GEOS-Chem version updates and is adaptable to other chemical transport models with similar modular input data structure. A post-processing
suite combines ensemble output into consolidated NetCDF files and supports a wide variety of diagnostic data and visualizations. We demonstrate
CHEEREIO's capabilities with an out-of-the-box application, assimilating global methane emissions and concentrations at weekly temporal resolution
and 2∘ × 2.5∘ spatial resolution for 2019 using TROPOspheric Monitoring Instrument (TROPOMI) satellite observations. CHEEREIO achieves a 50-fold improvement in
computational performance compared to the equivalent analytical inversion of TROPOMI observations.

Published: August 2023

Abstract. Regional coupled and Earth system models are fundamental numerical
tools for climate investigations, downscaling of predictions and
projections, process-oriented understanding of regional extreme events, and
many more applications. Here we introduce a newly developed coupled regional
modeling framework for the Mediterranean region, called MESMAR
(Mediterranean Earth System model at ISMAR) version 1, which is composed of
the Weather Research and Forecasting (WRF) atmospheric model, the NEMO oceanic model, and the hydrological
discharge (HD) model, coupled via the OASIS coupler. The model is implemented at
about 1/12∘ of horizontal resolution for the ocean and river
routing, while roughly twice coarser for the atmosphere, and it is targeted
to long-term investigations. We focus on the evaluation of skill score
metrics from several sensitivity experiments devoted to (i) understanding the
best vertical physics configuration for NEMO, (ii) identifying the impact of
the interactive river runoff, and (iii) choosing the best-performing
physics–microphysics suite for WRF in the regional coupled system. The
modeling system has been developed for downscaling reanalyses and long-range
predictions, as well as coupled data assimilation experiments. We then formulate
and show the performance of the system when weakly coupled data assimilation
is embedded in the system (variational assimilation in the ocean and
spectral nudging in the atmosphere), in particular for the representation of
extreme events like intense Mediterranean cyclones (i.e., medicanes).
Finally, we outline plans for future extension of the modeling framework.
In-silico calculation of soil pH by SCEPTER v1.0
Authors: Kanzaki Yoshiki , Chiaravalloti Isabella , Zhang Shuang , Planavsky Noah J. , Reinhard Christopher T.
Published: August 2023

Abstract. One of the soil properties most commonly measured to describe agronomic and biogeochemical conditions of soils is “soil pH”. Soil pH measures the concentration of exchangeable H+ that resides in bulk soil samples taken from the field, through aqueous H+ measurements of extractants (e.g., deionized water or electrolyte solutions) added to dried bulk soil samples in the laboratory. Therefore, “soil pH” differs from “porewater pH”, the latter of which we define here as an in-situ measure of porewater H+ concentration in soil/weathering profiles. The difference between the two pH measurements is often not fully known for a given system but could lead to a misunderstanding of soil conditions if the two measurements are directly compared. Agricultural soils are one of the targeted loci for application of the “Enhanced Rock Weathering” (ERW), a technique aimed at counteracting increasing anthropogenic carbon dioxide from burning fossil fuels, and an increase in pH is thought to be one of key advantages of ERW as this can mitigating soil acidification and secure crop yields. As a result, fully evaluating the biogeochemical and agronomic consequences of ERW approaches requires accurate simulation of both soil pH (pHs) and porewater pH (pHpw). This paper presents an updated version of the reactive transport code SCEPTER (Soil Cycles of Elements simulator for Predicting TERrestrial regulation of greenhouse gases), which enables simulation of bulk soil pH measurement in the laboratory in addition to porewater pH as measured in the field along with a more comprehensive representation of cation exchange with solid-phase constituents of bulk soil. We first describe the implementation of cation exchange in the SCEPTER model, then introduce conceptual modelling frameworks enabling the calculation of bulk pHs. The validity of the model is examined through comparison of model results with soil pH measurements from mesocosm experiments of maize production with crushed basalt amendments. Finally, illustrative example simulations are shown demonstrating that a difference between pHs and pHpw can lead to significantly different estimates of carbon capture by ERW for a given targeted pH in cropland systems.

Abstract. The European Beyond EPICA project aims to extract a continuous ice core of up to 1.5 Ma, with a maximum age density of 20 kyr m−1 at Little Dome C (LDC).
We present a 1D numerical model which calculates the age of the ice around Dome C. The model inverts for basal conditions and accounts either for melting or for a layer of stagnant ice above the bedrock. It is constrained by internal reflecting horizons traced in radargrams and dated using the EPICA Dome C (EDC) ice core age profile. We used three different radar datasets ranging from a 10 000 km2 airborne survey down to 5 km long ground-based radar transects over LDC. We find that stagnant ice exists in many places, including above the LDC relief where the new Beyond EPICA drill site (BELDC) is located. The modelled thickness of this layer of stagnant ice roughly corresponds to the thickness of the basal unit observed in one of the radar surveys and in the autonomous phase-sensitive radio-echo sounder (ApRES) dataset. At BELDC, the modelled stagnant ice thickness is 198±44 m and the modelled oldest age of ice is 1.45±0.16 Ma at a depth of 2494±30 m. This is very similar to all sites situated on the LDC relief, including that of the Million Year Ice Core project being conducted by the Australian Antarctic Division.
The model was also applied to radar data in the area 10–15 km north of EDC (North Patch), where we find either a thin layer of stagnant ice (generally <60 m) or a negligible melt rate (<0.1 mm yr−1). The modelled maximum age at North Patch is over 2 Ma in most places, with ice at 1.5 Ma having a resolution of 9–12 kyr m−1, making it an exciting prospect for a future Oldest Ice drill site.
Assessing lidar-assisted feedforward and multivariable feedback controls for large floating wind turbines
Authors: Guo Feng , Schlipf David
Published: August 2023

Abstract. We assess the performance of two control strategies on the IEA 15 MW reference floating wind turbine through OpenFAST simulations. The multivariable feedback (MVFB) control tuned by the toolbox of the Reference OpenSource Controller (ROSCO) is considered to be a benchmark for comparison. We then tune the feedback gains for the multivariable control, considering two cases: with and without lidar-assisted feedforward control. The tuning process is performed using OpenFAST simulations, considering realistic offshore turbulence spectral parameters. We reveal that optimally tuned controls are robust to changes in turbulence parameters caused by atmospheric stability variations. The two optimally tuned control strategies are then assessed using the design load case 1.2 specified by the IEC 61400 standard. Compared with the baseline multivariable feedback control, the one with optimal tuning significantly reduced the tower damage equivalent load, leading to a lifetime extension of 19.7 years with the assumption that the lifetime fatigue is only caused by the design load case 1.2. With the assistance of feedforward control realized using a typical four-beam lidar, compared with the optimally tuned MVFB control, the lifetime of the tower can be further extended by 4.6 years.

Atopic dermatitis (AD) is a chronic disease with a genetic basis. The physiological markers of the disease are inflammation and abnormalities in the efficiency of the body’s antioxidant system. The aim of this study was to analyze the possibility of using diet therapy to alleviate the course of AD. Based on information present in the world literature, available in Web of Sciences, Scopus, PubMed, and Google Scholar databases, the effect of food active ingredients in the course of this chronic disease was investigated. In the case of dermatoses, it is important both to eliminate foods that can exacerbate the course of the disease and to include in the menu ingredients that can alleviate the development of the illness. Diet therapy is the simplest and least cumbersome way to support the treatment of AD, even leading to the elimination of symptoms of the disease.

Skin aging is a natural, inevitable, biological and genetic process, which is defined as a set of irreversible changes that progress over time. It is believed that the first signs of skin aging are already visible at the age of 25. During this process, the biological involvement of the body’s cells in its renewal is reduced, and regeneration processes slow down. In order to maintain a good appearance, the help of an experienced cosmetologist is necessary, starting from proper skin diagnostics, followed care recommendations, to professional anti-aging therapies. No less important is the knowledge of active substances with anti-ageing potential. The aim of the study was to investigate the knowledge of beauty salon customers about active substances used in aging skin care.

Published: August 2023

Tissue fibroplasia, the combination of a biorevitalising mechanism with a biostimulant in a single mesotherapy preparation, is a relatively new group of injectable products. The study aimed to evaluate the effect of preparation with hyaluronic acid and sodium succinate on skin improvement in women with dry skin and clear signs of ageing. It showed a statistically significant decrease in skin echogenicity compared to the original state, an increase in skin thickness and a shallowing of individual wrinkles. Mesotherapy using the mechanism of tissue fibroplasia improves parameters of ageing skin, such as hydration level, thickness of the dermis, visibility of wrinkles, erythema, and skin discolouration.

The medieval sources provide some data on the bazaars of Samar-qand at that time. One of such source is the historical and biographical work “al-Qand fi dhikr ‘ulama’ Samarqand" (“Sweet in the Knowledge of Samarqand Scholars”) in Arabic by the famous Central Asian scholar-ency-clopedist Najm al-Din Abu Hafs ‘Umar ibn Muhammad al-Nasafi al-Maturi-di (460-537/1068-1142). Abu Hafs al-Nasafi was a resident of Samarqand and knew his hometown well. Therefore, his work contains valuable infor-mation on the historical topography of medieval Samarqand, in particular about its city bazaars and trading centers (rabats, tims), which played an important role in the economic life of our region.

Implications of decentralisation for disaster governance in Nepal’s federalism: Case study of COVID-19 response of four selected local governments

Nepal’s entry into federalism in 2015 resulted in a decentralised governance structure with constitutionally mandated legislative, executive and judicial functions for local governments. Existing research shows that devolving discretionary authority and resources to local governments is a necessary but not a sufficient condition for effective local responses during crises. However, there remains a need for deeper understanding about what makes local governments effective in responding to people’s needs during crisis times. Adopting a qualitative approach, this research analyses how decentralisation shapes local government responses in times of distress. We ask: How did local governments in Nepal respond to urgent needs during the COVID-19 pandemic – and what has been learned from this crisis that can make local governments better prepared for future challenges? Findings of this study show that the effective governance response to the crisis depends on several factors such as existing infrastructure development, availability of human and financial resources, political connections of local leadership, and local leaders’ ability to envision and execute the plans in a highly uncertain and quickly developing situation. The local government’s response to COVID-19 in Nepal shows the important role of decentralised local governance in combating crises, but there remain several critical challenges to make local governments more effective. In particular, we argue that it is essential to ensure sustained access to financial resources, strengthen human resource capabilities through training and capacity building activities, and prepare local governments to deliver important services in the context of disaster situations.
A Study on the Regulation of OTT Mergers under Competition Law

Published: August 2023

The Korean Fair Trade Commission's 2019 decision on the merger of Oksusu and POOQ is important in that it dealt with the first merger between major OTTs, but it is also meaningful in that it dealt with merger in areas where rapid industrial structure changes are taking place. The Korean Fair Trade Commission distinguished the significance of the merger into horizontal and vertical aspects, and recognized competition restraints based on the fact that increased concentration by merger parties in the broadcasting content provision market can negatively affect competition between OTT operators. At this point, it is difficult to avoid the perception that the judgment at the time was inappropriate, considering the rapid growth of Netflix and the continuous decline in the integrated OTT share after the merger. However, it is not possible to make a negative assessment of the innocence just by failing to predict. But the lack of a detailed analysis of the transaction of video content needed to be supported in order to recognize competition restrictions in the vertical sector, as the US courts did in the AT&T and Time-Warner business combination case, sufficient understanding of the competition pattern between OTTs centered on original content and consideration of the industrial situation in which innovative changes are occurring may be a problem. These problems will need to be corrected in the regulation of merger that may occur in the field in the future.
A Study on the Concept of Fundamental Right to Finance to Realize the Social Value of Finance: Focusing on the Legal Issues of Mortgage Loan Regulation
Authors:   Institute of Legal Myungji Uiversity, Park Kiju , Shin Dongho
Published: August 2023

The social value of finance is that, as finance exists and develops, the imperfect real economy becomes less incomplete, resources are allocated more efficiently at lower costs, and the realm of the market economy expands, contributing to economic growth. Recently, finance is pioneering new services based on artificial intelligence and data and launching various financial products. It is also true that there are concerns about whether or not the ordinary people will be alienated from the essential social functions of finance, such as financing and lending, in this process. If finance is used as an easy real estate policy tool by regulators without a legal basis, as shown in the example of the mortgage loan system, and if finance becomes a 'playground tilted' in the process of income and asset formation where the unfair game operates, it will distort the distribution function of the economy and act as a cause of exacerbating social inequality. Fundamental right to finance is a constitutional norm and standard that enhances the social value and function of finance by these regulatory authorities, and can be a kind of social agreement that determines the content and direction of regulation within the constitutional values ​​of the financial system. This study aims to establish the social value of finance and the legal concept of 'fundamental right to finance' based on the analysis of the institutional status and regulatory system of LTV, DTI, and DSR for mortgage loans implemented after the Moon Jae-in administration. Although finance provides a basic foundation for individual wealth formation in modern society, the reality is that it is not easy for ordinary people to fully enjoy the services provided by finance. From the point of view of economic democratization, discussions on financial democratization have been raised, and based on this, fundamental right to finance is mentioned in an abstract way, but it is also a reality that concrete research on this is insufficient. This study is expected to contribute to the discussion of fundamental right to finance based on the social value of finance in the future.
Unveiling the powerhouse: Exploring the dynamic relationship between globalization, urbanization, and economic growth in Bangladesh through an innovative ARDL approach
Authors: Ridwan Mohammad
Published: August 2023

Significant changes in the economic landscape of Bangladesh have occurred in recent decades due to variables such as globalization, urbanization, FDI, trade, population dynamics, and their interplay. Effective policies and strategies must be developed with a thorough comprehension of the interconnected dynamics of these factors and their influence on economic expansion. This study investigates the dynamic linkages between globalization, urbanization, foreign direct investment (FDI), trade, population, and economic growth in Bangladesh. The study employs sophisticated econometric techniques to analyze the impact of these variables on the nation's economic landscape from 1991 to 2021. The stability of the dataset is evaluated using stationarity tests including ADF, DF-GLS, and P-P unit root tests. The results indicate a varied order of integration estimation for the investigated variables, necessitating additional investigation. The Autoregressive Distributed Lag (ARDL) estimation technique is utilized to investigate the long-term relationship between the variables. The results demonstrate a positive and statistically significant relationship between globalization, urbanization, trade, FDI, and economic growth. The significance of external factors and urbanization in propelling Bangladesh's economic growth is highlighted by these findings. Surprisingly, during the examined period, population dynamics had no significant impact on economic growth. This emphasizes the need for policymakers to investigate the intricate relationship between population trends and sustainable economic growth. Using the Ramsey Reset test, Jarque-Bera test, Breush Godfrey LM test, and CUSUM & CUSUM square test, the model's dependability is rigorously evaluated. The results demonstrate the model's robustness and validity, bolstering the veracity of the study's findings. On the basis of the research findings, a number of policy recommendations emerge. To promote economic growth, it is recommended that Bangladesh continue to embrace globalization, encourage FDI, and strengthen international trade relations. In addition, policymakers should prioritize urban development to capitalize on the economic benefits of urbanization. To address population dynamics, a balanced approach is required. To maximize the potential of the young workforce, population control measures should be considered alongside investments in education, skills training, and healthcare.
