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.

Janeska, Aleksandra Lozanoska","doi":"10.5775/fg.2021.051.i","DOIUrl":"https://doi.org/10.5775/fg.2021.051.i","url":null,"abstract":"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.
