Abstract. The ancient Silk Road played a crucial role in cultural exchange and commercial trade between western and eastern Eurasia during the historical period. However, the exchanges were interrupted in the early 16th century CE, during the Ming dynasty. Various causes for the decline of the ancient Silk Road have been suggested. Unlike social factors, natural factors have not been adequately addressed. In this study, we use evidence from a sedimentary site (Xishawo, XSW) in Dunhuang oasis, together with analysis of historical archives, to demonstrate the occurrence of extreme droughts and desertification events in the Dunhuang area post ∼ 1450 CE, which persisted at least for decades. The desertification may be closely associated with the accessibility of the ancient Silk Road in the area, which was responsible for a steep fall in the volume of trade, as well as political chaos and mass migrations. Therefore, besides socio-economic factors, climate change may have played an important role in trade exchange between the Ming government and the West and may have even influenced the rise and decline of the ancient Silk Road.

Abstract. The Ancient Silk Road played a crucial role in cultural exchange and commercial trade between western and eastern Eurasia during the historical period. However, the exchanges were interrupted in the early 16th century AD, in the Ming dynasty. Three causes of the demise of the ancient Silk Road have been suggested: (1) the thriving of the sea trade route after the great geographic discovery in the Ming dynasty; (2) frequent incursions by the Wala and Turpan kingdoms, or fighting in border areas; and (3) climate change. In this study, new evidence from a sedimentary site in Dunhuang oasis together with analysis of historical archives indicate that neither the sea trade route nor the frontier wars were the pivotal reason for the closure of the Jiayuguan Pass. Extreme droughts and desertification events, caused by climate change, occurred in the Dunhuang area, west of the Jiayuguan Pass, during ~ 1440–1460 AD. After ~ 1450 AD, desertification rendered the ancient Silk Road impassable in the area, which resulted in a steep fall in the volume of trade as well as political chaos and mass migrations. The final closure of the Jiayuguan Pass in 1539 AD and the abandonment of Dunhuang city further interrupted the operation of the ancient Silk Road.

Poverty is a crucial and worldwide phenomenon. The main purpose of the study is to investigate the relationship exists between socio-economic factors, social factors, and poverty, the relative influence of economic and social factors on poverty and to describe causality between time series in the VAR system. This study utilized the Vector Error Correction Model (VECM) by using quarterly time-series data, 1994Q1 to 2018Q4, that have been collected from the world development indicators (WDI) and Economic Survey of Pakistan. The study identified education, unemployment, inflation as economic factors while zakat and rainfall as social factors that can reduce poverty. The findings of this study indicate that inflation and unemployment have a positive and significant relationship with poverty in the long run in Pakistan while education, rainfall, social welfare programs, and zakat has a negative relationship in the long run with poverty. Besides, the study also found that in the short run, there is no relationship between economic and social factors with poverty. Moreover, the study found that in the long run that the relative contribution of education and rain increases, 28% and 20%, is greater than the contribution of inflation, social welfare programs, unemployment and zakat, 3.8%, 0.5%, 2.5%, and 0.08%. Similarly, its contribution to poverty reduces up to 44% in the long run. This study helps policymakers to take important decisions about economic and social factors while designing policies to reduce poverty. The results suggest that the state bank of Pakistan should adopt a contractionary monetary policy to control inflation and policymakers can develop policies like education for all. The government should develop a business environment to create more employment opportunities.

Investing in cryptoassets can be tricky. At the moment, there are many different cryptocurrencies operating on different blockchains with different ecosystems. The use of cryptoassets requires defining a goal in relation to the type of cryptoassets and the degree to which their properties affect their functioning and development. In this article, the author analyzes two of the most popular and significant cryptocurrencies for the cryptoindustry Bitcoin and Ethereum on two different blockchains. The author specifically took two cryptocurrencies that are completely different in their meaning and purpose. In view of the fact that the author does not see an ideal solution to several problems, he described the need for diversification of assets by purpose of use. The author describes each cryptocurrency as a separate ecosystem with its own properties, which requires playing by the rules. The author cites socio-economic factors due to which he chose these two blockchains for analysis, tries to analyze the dependence of the properties of each cryptocurrency on the level of popularization, and gives empirical data stating the consequences in a historical context.The author also considers technical properties as a factor of scalability and attractiveness of each of the blockchains, how cryptocurrencies interact with each other, influencing the financial mood of users. The author of the article also tries to determine the technical and social factors that led to the adaptation of these cryptocurrencies to the traditional financial sector and how they depend on each other. The author describes Bitcoin as a system for saving and multiplying funds, while Ethereum sees it as an ecosystem, an intermediary protocol between already formed market sectors and decentralized applications within the network. After analyzing the results of the study, the author provides general criteria for the formation of a methodology for choosing a cryptocurrency and blockchain for conducting effective operational activities, as well as the formation of its own mechanism for managing the efficiency of cryptocurrency operations.

The article attempts to assess the impact of selected economic and social factors on the fiscal sustainability of 241 urban municipalities in Poland in 2004-2016. The article uses the econometric modelling of panel data. The analysis revealed that most of the variables had a negative impact on local fiscal performance. The main reason for this is the low fiscal autonomy of Polish cities and the strong dependency on grants from the central budget, as well as the high share of unfunded mandates. This situation means that cities are particularly sensitive to the external environment, while at the same time are deprived of fiscal stabilisation instruments allowing them to counteract this problem. It can be an important obstacle to achieving sustainable economic development.

There are still many uncertainties about how climate change affects the development of human society. The impact of climate change is likely to be weakened or amplified by the response and adaptation of the reciprocal feedback process after entering the socio-economical subsystem. The study of the climate change impact processes is the basis for understanding the mechanisms of climate change impacts. Furthermore, long-term research of climate change impacts can provide historical similarity and experience for current or future adaptation of climate change. Ancient China was traditionally an agricultural country. Its food production safety, food supply safety, and food consumption safety reflect the impacts of climate change being transferred from a production subsystem to a population subsystem to an economic subsystem. Based on a conceptual framework of food security, we selected 10-year resolution sequences of grain harvest grades, famine indices, and economic levels in China over the past 2000 years (206 BC–AD 1911) to quantify and recognize the main transmission pathways of climate change impacts during cold and warm units of climate change. Our results were as follows: (1) according to the transmission relationship climate change → grain harvests → famines → economic levels, there are 16 main transmission pathways, including 10 pathways starting from cold units and 6 pathways starting from warm units. (2) The main pathway is dominated by natural factors and socio-economic factors, with each factor set accounting for approximately 50%. However, the probability of the main pathways with socio-economic influence leading toward negative developments was 60% for cold units, and the probability of the main pathways with socio-economic influence leading toward positive developments was 66.7% for warm units. According to the main pathway led by natural factors, of all transmission pathways in cold units (100%), 14.7% of the depressed economy may be more directly related to climate change. However, 32.3% of the prosperous economy may have a more direct relationship with climate change in warm units (100%). (3) Famine is the most important link in the climate change influence on transmission chains regulated by socio-economic factors. Famine reflects both poor harvests due to the natural production subsystem and a lack of grain allocation by the socio-economic subsystem or the government’s ability to eliminate famine. Thus, there may be another pathway of transmission, such as climate change → agricultural yield/grain production → economic prosperity → famine relief (social vulnerability).
