Analysis of the Dynamic Changes and Driving Mechanism of Land Green Utilization Efficiency in the Context of Beijing–Tianjin–Hebei Synergistic Development

Studying the development of land green utilization efficiency and the factors that influence it in the Beijing–Tianjin–Hebei region can improve the distribution of land resources among regions and reinforce interregional integrated planning. By constructing a super-efficiency SBM model, calculating the Malmquist–Luenberger index, and constructing a Tobit model, this study explores the spatial features and temporal variations of land green use efficiency in the Beijing–Tianjin–Hebei region from 2010 to 2022. It also examines the mechanism that drives land green use efficiency in the context of the Beijing–Tianjin–Hebei synergistic development. According to this research, Beijing has consistently had the highest land green usage efficiency and a strong green development strength, whereas Baoding, Xingtai, Handan, and other cities in Hebei Province have lower land green utilization efficiency. According to the geographical dimension, the research area’s land green use efficiency exhibits a pattern of “high in the middle and low in the surroundings”, with Cangzhou, Langfang, and Tangshan standing out in terms of both industrial transformation and ecological building. Based on the results of the driving mechanism of land green use efficiency, it is evident that while the degree of urbanization and population concentration has a negative effect on land green use efficiency, the degree of economic development, industrial synergy, opening up to the outside world, environmental regulation, and ecological output all have positive and promoting associations with it. In summary, increasing the optimization of the economic and industrial structure, bolstering technological innovation and policy coordination, and attaining a harmonious coexistence of the economy and ecology are all essential steps in the process to increase the land green use efficiency in the research area when attempting to achieve the goal of sustainable development in the region.

Deep Learning-Based Pre- trained Model for Classification and Detection of Potato Leaf Disease

Abstract: From the Holocene period of the earth, formation of physical geography has started and the flaura's and faunna's had played a very huge role in supplementing to the earth. Apart from the whole earth India is the country that contributed about 7.68% of total world's farming output. The potatoes is an essential food crop worldwide, feeding billions of individuals. Nevertheless, the presence of different diseases has a significant impact on potato production and quality, resulting in substantial financial losses for farmers and potential concerns regarding food security. Detecting these diseases accurately and early on is vital for implementing effective strategies to manage them. In recent times, Convolutional Neural Networks (CNNs), a type of deep learning technique, have shown remarkable success in recognizing various objects in images. This work investigates the use of CNNs to identify diseases in potato leaves, aiming to aid in prompt disease diagnosis and protect crops.

Development a risk assessment method for dimensional stone quarries

Over the last 20 years, the global production of dimension stones has grown rapidly. Today, seven countries—China, India, Turkey, Iran, Italy, Brazil, and Spain—account for around two-thirds of the world's output of dimension stones. Each one has annual production levels of nine to over twenty-two million tons. Mining operation in general is one of the most hazardous fields of engineering. A large amount of dimensional stone quarries require a special scheme of risk assessment. Risk Breakdown Structure is one of the major stages of risk assessment. In this paper, a detailed structure of risks of the dimension stone quarrying is formed, and divided into 17 main levels and 128 sublevels. The complexity of identifying different parameters made it requisite to use multi-attribute decision-making methods for prioritizing associated risks. As a case study, the main risks of the Ghasre Dasht marble mine are evaluated using the VIKOR method considering 10 major parameters under a Fuzzy environment. The results showed that the economic, Management, and Schedule risks are the most threatening risks of dimensional stone quarrying.

Assessment of Polygenic Traits Association with Yield in Soybean Genotypes

Soybean is one of the important oilseed crop at global level with special concern to India. Despite its global dominance, India's contribution to the soybean scene remains relatively modest, with a production ranking of fourth but only a 5% share of the world's output. For this concern, the analysis of the relationships among yield attributing characters and their associations with seed yield is essential to establish selection criteria. The experimental material used in the present study comprised of fourteen lines (8 F1s and 6 parental lines). The characters viz., number of pods/plant, primary branches/plant, harvest index, plant height, secondary branch/plant, biological yield, 100-seed weight and days-to-50% flowering recorded significant positive correlation coefficient with seed yield both at genotypic and phenotypic level. Path coefficient analysis further pinpointed 100-seed weight, harvest index, and pods per plant as the traits with the most direct positive impact on seed yield. Additionally, the study identified plant height, pods/plant, primary branches/plant, 100-seed weight, and the harvest index as the key contributors to soybean yield, suggesting these traits as primary targets for manipulation in breeding programs aimed at yield improvement.

Global Spillovers of China's Monetary Policy

AbstractSpillovers from China's monetary policy have become increasingly obvious with China's growing importance in the global economy and its close economic and trade ties with the world. This study establishes a proxy structure vector autoregression model to investigate the magnitude and transmission channel of spillovers from China to global and regional economies, taking advantage of high‐frequency changes in asset prices in the financial markets to identify monetary policy shocks. The analysis reveals that China's monetary policy can affect the global economy by influencing international trade and commodity prices but there is no evidence of China's monetary policy affecting global financial variables. Tightness in China's monetary policy can cause a decline in world output whereas expansion in monetary policy can support global trade and output. This study also finds that the response of emerging Asian economies to China's monetary policy shock was nearly twice that of developed economies, while the transmission path did not change. The results of this study are consistent with the stylized fact that China's monetary policy plays an important role in the global trade and commodity cycle, although it does not drive the global financial cycle.

Navigating the Honey Markets Across Europe and Africa

India ranks fourth globally in terms of honey export but the Indian honey was mainly exported to American and Asian continent consisting of over 85 per cent of total honey exported by India leaving huge untapped potential in Europe which is second largest importer of honey worldwide as well as Africa. Keeping this in mind an analysis of European and African honey market was done using secondary data and results were interpreted in excel sheet. It was found that European honey production was primarily led by Spain. The continent accounted for approximately 45 per cent of global honey imports, with Germany being the largest importer with imported value of 306674.7 thousand USD (2023). India shared less than 0.1 per cent of total European honey imports. It was also observed that Africa contributed to 10 per cent of the world's total honey output. The continent’s honey import was considerably lower than global imports. In terms of export, Egypt led African honey exports. India shared only 12 per cent of total honey imports to Africa. It was noted that both Europe and Africa presented huge untapped potential for Indian honey. It was suggested to improve post harvest management of honey for maintaining quality standards and government support for increasing exports to the continents.

Global Impact of Soybean Production: A Review

Soybean is among the most significant crops in the world. Vegetable oil and protein meal both benefit from the use of soybean seeds. Soybean output has increased at the greatest percentage rate of any major crop during the 1970s. The crop is projected to be cultivated on 6% of the world's arable land. The recent surge in output is in line with the rising demand for oil and meal. Since soybeans are one of the most significant crops in the world, more study is being done to learn more about how they are produced under various circumstances, including stress. Information on the pace of soybean production throughout the globe may be utilized to enhance soybean production and mitigate variables like stressors that have a negative impact on soybean yield. The productivity of soybeans is significantly impacted by the action of soil bacteria. Only a few nations, including the United States, Brazil, Argentina, China, and India, account for the majority of the world's soybean output. For managerial and ecological reasons, it is crucial to have a deeper grasp of the vast range of farming techniques used in soybean crops. We will also talk about the potential relationship between improved management of microbial inocula and soil conditions. Gaining a deeper comprehension of the vast range of plant interactions is crucial for both managing and comprehending the ecology of this crop. Due to our direct and indirect reliance on the soybean crop for food goods, significant yield reductions in soybeans beyond present levels may have an impact on food security. Additionally, the crop provides resources to solve global food concerns via present and future use techniques due to its high nutritional value and versatility. Whether used as a vegetable crop or processed into a variety of soybean food products, soybean production is predicted to rise in the future in direct proportion to rising demand. With the application of newer genomic technologies, the crop has enormous potential to improve dietary quality for people worldwide.

Evaluation of Different Integrated Disease Management Approaches for Rhizome Rot of Ginger (Zingiber officinale Roscoe.) Caused by Ralstonia solanacearum (Smith.) under Field Conditions

Ginger (Zingiber officinale Roscoe.,) is a slender herbaceous perennial plant belonging to the family Zingiberaceae, medicinally important and commercial spice crop. India is the largest producer of ginger and accounts for about 1/3rd of the total world output. Ginger is grown in Kerala, Karnataka, West Bengal, Andhra Pradesh, Orissa, Arunachal Pradesh, Sikkim and other parts of India. The production of ginger is greatly influenced by diseases caused by bacteria, fungi, viruses, mycoplasma and nematodes. One of the diseases of ginger is bacterial wilt caused by Ralstonia solanacearum, which causes yield loss of up to 80 percent. A field experiment was conducted with integrated approaches to manage the ginger rhizome rot caused by R. solanacearum (Smith). The experiment was laid out with a Randomized Completely Block Design (RCBD) including nine treatments and four replications. The experiment results revealed that, rhizome treatment with Streptocycline @ 0.5 g + COC @ 3.0 g/l of water + soil application with neem cake 3q/ha followed by drenching with bleaching powder (33%) @ 2.0 g/l + Metalaxyl MZ @ 1.0 g/lit for water three times at 20 days intervals + Ginger special spray 45 DAS, starting with the initiation of the disease was significantly most effective and recorded a higher yield of 110.27 q/ha with least disease incidence of disease (14.23 %). Integrated management of rhizome rot of ginger through soil solarization revealed that, among the different treatments, the treatment treated with soil solarization + rhizome treatment with Streptocycline @ 0.5 g + Copper Oxy Chloride @ 3.0 g/lit of water + Soil application of Pseudomonas fluorescens @ 10 kg along with 25t FYM /ha recorded higher yield of 115.23 q/ha with less percent disease incidence (8.20 %).

World Output and Commodity Price Cycles*

This study investigates the cyclical patterns of energy, agriculture, and metals and minerals (MetMin) commodity prices. We identify three super cycles since 1960, and a potential fourth arising from the Ukraine crisis and global COVID-19 pandemic. Employing a Structural Vector Autoregression (SVAR) approach, we establish an empirical relationship between output, CPI, and commodity prices. Our analysis reveals that an output shock leads to a general increase in all commodity prices, where the highest impact is on energy inflation. Moreover, we examine the heterogeneous effects of commodity inflation on overall inflation, uncovering ‘second round' effects across all commodities. Notably, agriculture inflation has the most significant impact on aggregate inflation, potentially explaining the destabilizing nature of food inflation in many countries. Our findings enhance understanding of these dynamics, offering important insights for policymakers and informing the public. Highlights We analyze the cyclical patterns of energy, agriculture and MetMin commodity prices. Real output, CPI and commodities exhibit the same cyclical patterns. A shock to output increases all commodities, where the highest response is energy inflation. We find ‘second-round' effects, where agriculture prices have the highest impact on inflation.

The study reports the consumer welfare effect of the implementation of RCEP in Malaysia.Originality/valueThe study is the first attempt to do a partial equilibrium analysis for the electrical machinery and equipment sector and inorganic chemicals sector of Malaysia using both aggregated and disaggregated data at HS two-digit and HS six-digit level.

EU의 공동외교안보정책과 우크라이나 전쟁

This paper seeks to anlayze whether the Capability-Expectations Gap (CEG) of the European Union’s Common Foreign and Security Policy has been narrowed after the War in Ukraine broke out on 24th February 2022. It compares in the components of the CEGs before and after the war. Christopher Hill defines the capability as being composed of the resources (economic and diplomatic), policy instruments and policy cohesiveness.
 Before the war, Brexit left the EU’s economic power dwindled by 2.17% point from 15.7% to 13.62% in world output. Policy instruments have seen some changes, as the EU could manage to give military as well as economic aid to Ukraine for the first time. Although the EU is not a military alliance, EU leaders could reach agreements on sending military equipments in the face of Russian aggression. Policy cohesiveness refers to the ability to reach agreements and implement such ones among differing national policy preferences. Hungary remained opposed to banning Russian oil and gas imports to the last moment, thus gaining exemption from the EU’s sanction until the end of 2023, at least a year later after such sanction entered into force.
 With regard to expectations from within and without of the EU, citizens in Europe have wanted the bloc to play a more active role in major international affairs such as in the Ukraine War. The EU also could follow through many sanctions in close consultation with the United States, which has led Western efforts in giving aid to Ukraine.
 EU’s international role is likely to grow in the process of mediating the war, as the war is probably to last another a year or two. It will also shoulder significant burden to help Ukraine reconstruct after the War.

Global financial uncertainty

SummaryWe estimate a novel measure of global financial uncertainty (GFU) with a dynamic factor framework that jointly models global, regional, and country‐specific factors. We quantify the impact of GFU shocks on global output with a VAR analysis that achieves set identification via a combination of narrative, sign, ratio, and correlation restrictions. We find that the contraction in world output during the Great Recession would have been 13% milder in absence of GFU shocks. We also find support for a global finance uncertainty multiplier: the more global financial conditions deteriorate after a GFU shock, the larger the world output contraction is.

Does Globalization Worsen Environmental Quality in ASEAN Countries?

The era of globalization, which is characterized by integration between economies, increases world output, but environmental damage becomes an important concern to achieve sustainable growth. Therefore, this study intends to estimate the impact of globalization in economic, social side and political terms together with the variables of GDP per capita, financial development and energy spending on carbon emissions and to prove the presence of Kuznets Environmental Curve Hypothesis in ASEAN using panel data over 2000-2019 period. The results of the study proved that globalization, especially social globalization, and energy consumption have role in escalating environmental damage. GDP per capita is found in the reduction of carbon emissions but financial development was discovered to have no significant impact on increasing carbon emissions. This study does not prove the presence of EKC. Hence, this proposes crucial implications for policy makers. These findings suggest that the policy makers to make sustainable energy development strategies while increasing regional income and economic development through globalization.

Emerging market economies and sustainable development of global economies-challenges and opportunities

Emerging Market Economies (EMDE) are facing challenges and the performance of the Large Emerging Market (LME) economies are also with issues of concern and makes global development a fix. The global slowdown and financial crisis bring uneven development. Adding to this, epidemics like COVID-2019 also pushed the world economies down by at least 0.04 percent with its cascading effects to come in the future. The trade positions in the EMDE regions were weak due to uncertainties and lower demand for commodities. The financial markets were in stress, investment has reduced, lower capital, low productivity, lesser business climate etc., in the EDMEs. The real GDP of EDMEs is expected to grow an average of 6.2 percent during 2017-21 and it is 0.3 percent lower than 2016 position. Advanced economies perform comparatively lower in the world output. The output of Emerging and Developing Asian countries output was 6.6 percent in 2017 and it declined to 6.4 percent in 2019

Digital Marketing and Sustainable Economic Development Trends in Developed and Underdeveloped Countries: A Bibliometric Analysis

Abstract. The level of socioeconomic development depends on the mode of production, and the world economies have undergone revolutions from agricultural, industrial, and then digital, giving rise to developed, developing and underdeveloped economies. The purpose of this research is to use bibliometric analysis to study the trends of digital marketing and sustainable development in developed and underdeveloped countries. The authors resorted to the Scopus database to extract 119,981 documents for developed economies and filtered them to 29,071 for Scopus analysis. Then, 9854 documents were also extracted for underdeveloped economies and refined to 2850 to perform comparative analysis. The filtered documents were exported to VOSviewer for visualization mapping, including coauthorship and co-occurrence analysis using English. The results revealed that the total number of documents produced in developed economies from 1950 to 2023 was 29065, compared to 2816 produced in underdeveloped economies, representing just 8.9% of the total world output. The study revealed a general upward growth trend in both developed and underdeveloped economies. The results further revealed that developed economies strengthened their research collaborations, the United States was the most influential for developed economies, and China was the most influential in research done in developing economies. The research findings indicate that digital marketing has been the most influential among the cowords and the main driver of the global economy between developed and underdeveloped.

Inaugural Address

Sardar Aseff Ahmad Ali, Deputy Chairman, Planning Commission, Dr Rashid Amjad, President, Pakistan Society of Development Economists, Honourable Ministers, Excellencies, Ladies and Gentlemen! It is indeed a privilege and honour to address this distinguished gathering of economists. I am very happy that this meeting is being attended by internationally acclaimed economists and academics from both within and outside the country. I am especially heartened to see that students of economics from all over Pakistan have been especially invited to attend this meeting. Over the years the Annual Conference of the Pakistan Society of Development Economists has become one of the leading events on the calendar of meetings where experts from various disciplines discuss cutting edge issues that confront developing economies in general and Pakistan’s economy in particular. The Pakistan Institute of Development Economics is to be congratulated for holding such conferences on an annual and regular basis. The President of the Society has mentioned that I have actively encouraged the participation of economic experts, academics and researchers in the policy planning process. I firmly believe that this interaction will lead to framing of economic policies that respond to our economic needs and lead to more sustainable and equitable economic growth. I will continue to involve our body of economists in formulating policies and thank you for your offer to work closely with our government. The theme of this year’s Meeting “Economic Sustainability in a Globalised World” is very timely and touches the very heart of the economic challenge we face at the global and national level. The world has witnessed a global financial meltdown which started in the USA but spread to other parts of the world, both developed and developing. This financial crisis has now hit the real economy, causing a massive decline in global manufacturing output and global trade which is the worst since the Great Depression in 1929. World output is projected to shrink in 2009 and world trade expected to decline markedly this year.

Innovative use of micronized biomass silica-GGBS as agro-industrial by-products for the production of a sustainable high-strength geopolymer concrete

Micronized biomass silica (MBS) and ground granulated blast furnace slag (GGBS) are agro-industrial byproducts generated by incinerating of rice husk (grinding in jar mill) and blast furnaces that used produce iron, respectively. MBS accounts for 20% of the world's total paddy output of 590 million tons. These by-products (MBS and GGBS) have a high concentration of amorphous silica, which is utilized as a mineral additive in concrete. This amorphous silica interacts with hydration products, resulting in the formation of additional CSH gel. This improves concrete's strength and durability properties. Therefore, it is proven that inclusion of agro-industrial by-products in concrete helps to promote sustainable and greener development, which in turn reduces carbon footprints and waste that must be disposed of in landfills. There have been few investigations on concrete using MBS and demonstrated the great potential of employing MBS as a cement substitute or additive in normal concrete. Also, the utilization of MBS as partial replace to GGBS in geopolymer concrete (GPC) with different molarity is a novel aspect of this study. However, this study has the aim and limit to develop a high-strength eco-friendly GPC with agro-industrial byproducts (MBS and GGBS) for use in sustainable construction. The impact of incorporating MBS as a partial replacement of GGBS on compressive and split tensile strengths, sorptivity, and chloride permeability was tested up to the age of 28 days. MBS was used to replace GGBS in varying percentages in the preparation of concretes. MBS were used in concrete at 0%, 10%, 20%, and 30% replacement by weight. It was discovered that a GPC combination containing MBS 20% and the balance GGBS as the binder had the best performance in terms of its strength and durability. The compressive strengths of all GPC mixtures exceeded the intended design strength. The main findings of this study demonstrated clearly that MBS may be employed as a binder in the production of GPC.
