Currently, remote sensing is widely used in environmental monitoring applications, mostly air quality mapping and climate change supervision. However, satellite sensors occur massive volumes of data in near-real-time, stored in multiple formats and are provided with high velocity and variety. Besides, the processing of satellite big data is challenging. Thus, this study aims to approve that satellite data are big data and proposes a new big data architecture for satellite data processing. The developed software is enabling an efficient remote sensing big data ingestion and preprocessing. As a result, the experiment results show that 86 percent of the unnecessary daily files are discarded with a data cleansing of 20 percent of the erroneous and inaccurate plots. The final output is integrated into the Hadoop system, especially the HDFS, HBase, and Hive, for extra calculation and processing.

“…Morocco spans an area of 710 850 km 2 and has a population of over 36 471 769 inhabitants (2019) [10]. This assessment, based on the analysis of data from air quality monitoring stations, before, during and after the state of health emergency [11]. This assessment will allow for a more detailed analysis of the air pollution situation, including the baseline, to draw lessons and make recommendations to limit post-COVID19 air pollution [12].…”

Evolution of air quality in Morocco before and during the COVID-19 pandemic; comparative study

The epidemic of coronavirus is spreading all over the world, which is not only a health problem, but also affects the social sector, politics, the environment in various ways and the world economy. In response to the rapidly changing international epidemiological situation of COVID-19, several governments have imposed restrictions on the movement of people and vehicles and suspended industrial activities as a safety measure to reduce the spread of the virus and protect human health. This study aims to compare the state of air quality in Morocco, before the pandemic and during the lockdown situation of the Moroccan territory between March 2020 and June 2020.

“…Indeed, the United Nations has asserted that clean air is one of the necessities for human health and wellbeing [18,19]. There have been several studies on the assessment of air quality in urban environments in the developing world [20][21][22][23][24][25][26][27][28][29][30] and approaches include the use of automated monitoring stations, computer models and, more recently, earth observation (EO) via satellites [31][32][33]. However, these are often expensive and require technical skills to operate, maintain and interpret [34,35] and the cost and need for expertise and equipment can restrict their use in an urban environment in the developing world [34,[36][37][38].…”

Poor Air Quality in Urban Settings: A Comparison of Perceptual Indicators, Causes and Management in Two Cities

2022

Poor air quality (PAQ) is a global concern, especially in urban areas, and is often seen as an important element of social sustainability given its negative impact on health and quality of life. However, little research has been undertaken in cities of the developing world to explore how residents perceive poor air quality, its main causes, what control measures should be used to address PAQ and where the main responsibility rests for implementing control measures. The research described in this paper sought to address these points, using a questionnaire-based survey (n = 262) in Nigeria’s federal capital city of Abuja (n = 137) and the state-capital city of Enugu (n = 125). The survey took place during the COVID-19 pandemic (October 2020 to March 2021), and was stratified to ensure representation across a number of demographic groups such as gender, age, education and income. The results were analysed using the Kruskal–Wallis non-parametric test and Hochberg’s post hoc test available in SPSS version 28. The study found that the ranking of perceptual indicators and the main causes of PAQ had much agreement between respondents from both cities and between demographic groups. Smoke, odour and dust particles were perceived to be the most important indicators of PAQ, while the main sources of PAQ were waste and bush burning, vehicle use and power generators. The two most preferred control measures were proper waste management and the avoidance of bush burning. However, there was a significant difference between the two cities in terms of the main organisations responsible for addressing PAQ, with respondents from Abuja citing the federal government, while those from Enugu cited the state government. Interestingly, younger people in Enugu noted that the government should take more responsibility in controlling PAQ than did the older demographic in that city, but this difference was not seen in Abuja. Overall, this study reveals that residents in these two Nigerian cities clearly recognise their exposure to PAQ and it suggests that these perceptual indicators, and views on sources and interventions should be central to designing policies to control this important issue.
