Towards the end of 2019, a novel contagious virus (COVID-19) came out of Wuhan, China and turned into a disastrous pandemic. Many countries were completely or partially locked down. The ongoing pandemic has greatly affected our society and economy but, on the other side, it had effects upon the natural environment, as it rejuvenated itself. The present study repots the air quality and spatial distribution of air quality parameters (PM10, PM2.5, NO2, SO2, O3 and CO) in Delhi, taking into account data from 36 monitoring stations, for the months of January - April 2019 and 2020, respectively before and during the COVID-19 pandemic. The statistical tools like box plot, Pearson's correlation, and PCA were used to interpret air pollution data before and during the lockdown period. The results revealed the characteristics of pollutants with respect to location, relationship between pollutants, and monitoring their level in compliance with the limits set by the legislation. The results of multivariate analysis were further spatially analyzed by mapping the distribution of pollutants by using the Inverse Distance Weighted interpolation. The result revealed the gradual reduction in the pollutant concentrations (PM10, PM2.5, CO, SO2) and an increment in ozone concentration was observed, which was due to a drastic reduction in NO2, especially during March and April 2020, immediately after the declared lockdown in the region. The overall study indicated that the interventions for urban air pollution mitigation are crucial in the regeneration of nature. © 2021 University of Craiova, Faculty of Social Sciences, Department of Geography.

2019年底,一种新型传染性病毒(COVID-19)从中国武汉传出,演变成一场灾难性的大流行。许多国家被完全或部分封锁。当前的大流行病极大地影响了我们的社会和经济,但另一方面,它也对自然环境产生了影响,因为它重新焕发了活力。本研究利用2019年1月至4月和2020年36个监测站的数据,分别在2019冠状病毒病大流行之前和期间,报告了德里的空气质量和空气质量参数(PM10、PM2.5、NO2、SO2、O3和CO)的空间分布。采用箱形图、Pearson’s correlation和PCA等统计工具对封城前和封城期间的空气污染数据进行了分析。结果揭示了污染物在位置、污染物之间的关系方面的特征,并根据立法规定的限制监测其水平。采用逆距离加权插值法对多变量分析结果进行空间分析。结果显示,污染物浓度(PM10、PM2.5、CO、SO2)逐渐下降,臭氧浓度增加,这是由于二氧化氮急剧减少,特别是在宣布封锁后的2020年3月和4月。总体研究表明,缓解城市空气污染的干预措施对自然的再生至关重要。©2021克拉约瓦大学社会科学学院地理系。版权所有。

How is COVID-19 reshaping temporary and circular labour migration: Serbia and North Macedonia perspectives COVID-19如何重塑临时和循环劳动力迁移:塞尔维亚和北马其顿的观点

The COVID-19 pandemic has caused migrant workers worldwide to face numerous and specific challenges. This study aims to determine how the COVID-19 pandemic and its societal impact have influenced temporary and circular migrants from Serbia and North Macedonia. Semi-structured in-depth interviews were conducted with 50 participants to gain a deeper understanding of their challenges and migration practices. Temporary circular labour migration from Serbia and North Macedonia are most intensive towards EU countries, which are geographically close and well-connected by traffic, and with which migrants have well-established migration ties. The results show that after the outbreak of the pandemic, respondents faced termination of employment contracts, reduced working hours and earnings. Most of the respondents returned and only a few found formal employment in the country of origin. Job-related impacts of COVID-19 on respondents are determined by temporary residence, a form of employment and the employment sector. Temporary and circular migrant workers from Serbia and North Macedonia involved in the essential sectors in EU countries are less likely to be severely affected by the economic impact of the COVID-19 pandemic. The results suggest that temporary and circular migration schemes should be improved after the pandemic, in a way that is sustainable even in times of sudden changes. In that regard, in addition to considering the needs of the labour markets of countries of origin and destination, the needs and the rights of migrants, should be prioritized in common solutions. © 2021 University of Craiova, Faculty of Social Sciences, Department of Geography.

2019冠状病毒病大流行使世界各地的移徙工人面临许多具体挑战。本研究旨在确定COVID-19大流行及其社会影响如何影响来自塞尔维亚和北马其顿的临时和循环移民。我们对50名参与者进行了半结构化的深度访谈,以更深入地了解他们面临的挑战和移民实践。来自塞尔维亚和北马其顿的临时循环劳动力迁移最集中于欧盟国家,这些国家地理位置接近,交通便利,移民与这些国家建立了良好的移民关系。调查结果显示,疫情爆发后,受访者面临劳动合同终止、工作时间减少和收入减少的问题。大多数答复者返回,只有少数人在原籍国找到正式工作。COVID-19对受访者的工作相关影响取决于临时居住、一种就业形式和就业部门。在欧盟国家重要部门工作的来自塞尔维亚和北马其顿的临时和循环移民工人不太可能受到2019冠状病毒病大流行经济影响的严重影响。结果表明,在大流行之后,应以即使在突然变化时期也是可持续的方式改进临时和循环移民计划。在这方面,除了考虑原籍国和目的地国劳动力市场的需要外,在共同解决办法中还应优先考虑移徙者的需要和权利。©2021克拉约瓦大学社会科学学院地理系。版权所有。
