“…Therefore, significantly more accurate results could be obtained (Figure 4a-c). In order to track changes in agricultural areas, this study uses imagery from both Landsat 7 (L7) for the years 2000 and 2010 and Landsat 8 (L8) for the year 2020 (see Table 2), under cloud-free conditions to obtain high-quality images, which reduces the inclusion of omission errors in cloud/cloud shadow [22]. All of the processing tasks were conducted in the GEE platform.…”

This article aims to investigate the complex relationship between a local population and its natural and urban environment. The study area, which was previously dominated by cereal cultivation, is currently facing profitability challenges due to climate change, water scarcity, rapid urban expansion, and the overexploitation of aquifers, influenced by changes in agricultural practices, which are disrupting the local ecosystem. This study relies on three interconnected indicators, population growth, climate change effects on agriculture, and the NDVI (Normalized Difference Vegetation Index), and reveals the impact of these factors on agricultural practices. Google Earth Engine was employed to determine the urbanization and greenness indices using scripts. The significant findings of this study demonstrate the remarkable demographic growth of 49.96% during the study period (2000–2020). Furthermore, this growth has led to a new trend towards intensive farming, with a substantial increase in irrigated lands by 44.19% and a multiplication of protected crop lands by 20 times, rising from 19.88 to 405.89 hectares. Additionally, horticultural production surged by 212.4% during the same period. Moreover, groundwater levels shifted from less than 50 m in the northern regions to less than 150 and 300 m in the southern part of the study area. The water potential in the study zone cannot meet the demands of the new agricultural orientation, which tends to deplete local groundwater, potentially causing recurrent shortages of agricultural products. This study underscores the importance of incorporating agricultural production into future urban planning and development programs to maintain a renewed balance between built environments and agriculture in peri-urban areas.

The geographical location of Kazakhstan, situated in the central part of the Eurasian continent, has played a crucial role in shaping a distinctly continental climate. This positioning has led to Kazakhstan facing a significant challenge in terms of water resource availability. The country’s water resources are highly vulnerable to the dual pressures of climate change and human activities. It is noteworthy that the Yesil River basin is the sole region within Kazakhstan’s borders where water resources are predominantly generated, while all other river basins experience substantial outflows beyond the nation’s boundaries. This research undertaking involves a comprehensive analysis of long-term climatic data collected from meteorological stations located within the confines of the Yesil basin in Northern Kazakhstan. Additionally, the study encompasses the computation of water consumption and annual runoff within this region. Historical meteorological observations spanning from 1961 to 2020 reveal notable trends. Most significantly, a 1.2 °C increase in temperature is observed during the spring season. Winters have also become relatively milder and warmer, particularly towards the end of February, where temperatures have shifted from −16.2 °C in the first 30-year period to −14.6 °C in the second period. These findings underscore the ongoing climatic changes within the region, with significant implications for the management and sustainability of water resources in Kazakhstan.

The concept of aerosol refers to the combination of microscopic solid or liquid particles present in the atmosphere along with a mixture of gases. These particles are suspended in the air at different sizes and are evaluated based on their ability to scatter or absorb light, which is quantified through a measurement known as aerosol optical depth. These particles' quantities are determined using specialized devices, commonly referred to as "aerosol optical depth meters" or "optical thickness meters." Additionally, through remote sensing technology, aerosol optical depth can also be measured via satellites. In this study, aerosol optical depth has been examined temporally and spatially in the Karabük province for 2022. For this aim, data from National Air Quality Monitoring Stations (NAQMS) situated nationwide was employed, along with MODIS satellite images. Data from five stations in Karabük province, namely Kardemir1, Kardemir2, Tören Alanı, 75.yıl, and Safranbolu, were used for temporal analysis, while satellite imagery was used for spatial analysis. The relationship between aerosol optical depths derived from MODIS satellite data using green and blue band information and station data was investigated. As a result, a 99% positive correlation was found between the two bands obtained from the MODIS satellite, and a significant correlation was observed between ground-based particulate matter 2.5(PM2.5) and particulate matter 10 (PM10) data. Data from the Tören Alanı station, which had a higher amount of data (357 days) compared to other stations, was used to determine this correlation. It was found that there was an 86.35% positive correlation among particulate matters. A moderate correlation was also identified between ground-based data and aerosol optical depth obtained from satellite imagery.
