The Impact

In this COVID-19 epidemic, due to insufficient awareness of the impact of sudden public health emergencies on agricultural logistics at this stage, agricultural products were left unsold, stocks were backlogged, and losses were severe. In the process of distribution, we should not only ensure a short time cycle and avoid the contamination of agricultural products by foreign bacteria, but also pay attention to the waste of human, material, and financial resources. Therefore, this study mainly adopts the combination of the petrochemical network and block chain to build an agricultural products emergency logistics model. This paper first shows the operation mechanism of the petri dish network and blockchain coupling in the form of a graph and then uses the culture network modelling and simulation tool PIPE to directly verify the construction model. It is proved that the structure and overall business process of the agricultural products logistics system constructed by combining the Petri net and block chain are reasonable, reliable, and feasible in practical application and development. It is hoped that this study can provide a reference direction for agricultural emergency logistics.

The Impact

In today’s world of swiftly increasing global economy and continuously changing international trade laws and technology exchange rate plays a pivotal role in the production, price formation, export and import of agricultural products. For many years exchange rate as an integral part of agricultural economics has been ignored. The present study was intended to investigate exchange rate as an impacting factor on the agricultural production. It also considers the researches that have been carried about the impact of the exchange rate on prices and export of agricultural products, theirs analyses and how much impact it has in the situation of Uzbekistan.

The West, chiefly Europe, left political footmarks in Africa from the Colonial Era, along with varying economic footprints and surviving engagements in the immediate Post-colonial Era. However, the relationships between Africa and her former colonial masters have hardly yielded much to the former following the wave of independence, leading to the perception of failed relationships. This perception of failure to deliver on their undertakings has left Africa with only one option—China. The latter has been addressing some of Africa’s urgent infrastructure needs in return for natural resources and agricultural products. These engagements on the surface appear to be good business, but on further examination seem questionable notably as it relates to debt distress on vulnerable economies. To increase her footprint within the continent, China extended her Belt and Road Initiative (BRI) to most African nations who have signed a memorandum of understanding for future development projects. Though the commitments usually are unspecified, China’s investments have seen rapid growth since the early 2000s, largely owing to the implementation of the BRI. The memoranda have had the potential to strengthen ties with partner nations. The expansion to include Africa in its economic participation in the BRI has left the West questioning China’s motives while reinforcing suspicions about possible future US-China conflict. The impact of BRI on the African continent is quite visible in all the subregions, especially in their improved gross domestic products. A burning question has been whether these partnerships represent win-win relationships for sustainable growth or debt-growth dynamics.

The infectious disease COVID-19 has swept across the world in 2020, and it continues to cause massive losses of life and severe economic problems in all countries. Providing emergency supplies such as protective medical equipment and materials required to secure people’s livelihood is thus currently prioritized by governments. Establishing a reliable emergency logistics system is critical in this regard. This paper used the Delphi method to design a formal decision structure to assess emergency logistics system reliability (ELSR) by obtaining a consensus from a panel of experts. Assessing ELSR is a typical multiple-attribute decision making (MADM) problem, and the related MADM methods are usually on the basis of symmetry principles. A hybrid MADM model, called the Decision Making Trial and Evaluation Laboratory (DEMATEL)-based Analytical Network Process (D-ANP), was developed to identify the critical factors influencing ELSR. An analysis of empirical evidence showed that the emergency logistics command and coordination system and the emergency material supply system play important roles in ELSR, while the emergency logistics transportation and distribution system and the emergency information system are not so important. This conclusion is different from previous research about traditional disaster emergency logistics. Moreover, the cause–effect relationships among the key factors indicated that the system of command and coordination for emergency logistics and the supply system for emergency materials should be improved. Accordingly, effective suggestions for emergency logistics services for epidemic prevention are provided in this paper. The main contributions of this paper are (1) establishing a comprehensive and systematic evaluating index of ELSR for epidemic prevention; (2) employing a kind of structured, namely D-ANP, to identify the critical factors with non-commensurable and conflicting (competing) characteristics; and (3) comparing the differences of reliable criteria between the emergency logistics of epidemic prevention and the traditional disaster emergency logistics.

Emergency logistics system contains information on material reserves, emergency command and emergency distribution. In this paper, the aspect of emergency distribution only is analyzed in microscopic, mathematical model of emergency logistics distribution has been established in considering the traffic situation and shortage degree. On the aspect of model solution, improved ant colony algorithm, which can enhance the selectivity of finding the best solution in emergency logistics distribution routing, is used in solving the model.

China is a vast country with 800 million farmers. An amelioration of their general living condition is a pressing issue. In China, it is not uncommon to encounter lower grain price due to the delays in their transportation. There are many reasons for the low living standards in rural areas, the obsolete rural logistic system, especially regarding agricultural products, is obviously one of them. Recently, to improve logistics development conditions of China's agricultural products, every levels of government increased rural logistics investment in construction projects; however, there are still delay issues from the productions centers to the urban areas. This paper looks the breaks in the logistics chain by studying the current distribution style, and proposes logistics system based on supply and marketing cooperatives in order to improve the existing system.
