“…In both years, NDVI and NDBI did not correlate well with the chemical parameters of water, but NDVI showed a significantly negative correlation with NDBI at p < 0.001 with r = −0.86 and r = −0.94 in 2015 and in 2021, respectively. Alam et al (2022) also found a negative correlation between NDBI and NDVI, concluding that NDVI shows a decreasing trend when urbanization increases and our findings concur with theirs [85]. Without these two LULC indices, As and Fe 2+ did not reveal any correlation with other water quality parameters either.…”

Land is a vital component of nature around the world and is essential for humans, terrestrial plants, and animals. However, urbanization is growing worldwide and the groundwater quality in urban areas is declining due to rapid development, industrialization, and pollution. Hence, it is important to determine the hydrogeochemistry and changes concerning land use and land cover (LULC). This study was conducted to investigate the hydrogeochemical mechanism of Sargodha, one of Pakistan’s fastest-growing cities, during 2015 and 2021 under two different LULC indices named normalized difference vegetation index (NDVI) and normalized difference built-up index (NDBI). Forty-eight groundwater samples were collected in 2015 and 2021 to assess groundwater quality for domestic use and irrigation. The Piper diagram revealed that (Ca2++Mg2+–HCO3−+CO32−) and (Na++K+–SO42−+Cl−) were the main components of hydrogeochemistry in both years. The Gibbs plot and silicate weathering of groundwater samples indicated that rock dominance and silicate weathering played a major role in aquifers. Additionally, the results showed that 4% of the groundwater in 2015 and 21% of the groundwater samples in 2021 were unfit for human consumption. However, 37% and 40% of samples were considered not fit for irrigation in 2015 and 2021, respectively. The LULC, NDVI, and NDBI clearly revealed higher urban areas in 2021 compared to 2015. The relationship between groundwater parameters and land use land cover indices (NDVI and NDBI) explained that none had a major relationship. The non-carcinogenic risk showed health quotient HQ < 1, indicating no severe health risk due to nitrate (NO3−) exposure in the city. The current study suggests conducting future investigations considering a larger scale to recommend efficient management strategies, urbanization planning, and ensuring safe irrigation and drinking water to prevent groundwater pollution.

“…LST in vegetation-covered areas can be lower because the temperature is regulated by the vegetation through processes such as transpiration, which helps maintain a cooler temperature due to higher oxygen production. The analysis of land cover, vegetation index, and their relationship with land surface temperature is crucial for environmental monitoring, weather conditions, and climate assessment (Alam, Alam et al, 2022). The LST and NDVI indices were influenced by climatic conditions, so it is important to observe the climate during the acquisition of satellite image data for the study (Table 4).…”

Small islands have unique ecosystems and are vulnerable to land degradation and ecological threats. Integrating spatial and landscape ecology approaches greatly influences the effectiveness and efficiency of environmental monitoring and future environmental management planning. Uncontrolled land conversion, extreme climate conditions, high biophysical land constraints, and anthropogenic and political factors contribute to biodiversity pressures. This study aimed to measure the impact of land use and land cover changes on the LST, NDVI, and NDWI as well as changes in landscape patterns and structures for environmental monitoring and ecological sustainability on Kapota Island. The LST values in 1990 ranged from 21.50°C to 25.40°C, and from 22.63°C to 32.56°C in 2020. In contrast, the NDVI values in 1990 ranged from -0.765 to 0.754 and from -0.241 to 0.514 in 2020. The surface temperature increased in vegetated areas with low density, as well as in non-vegetated areas and settlements. Habitat fragmentation was relatively high, as indicated by the SHDI value closer to 1. Moving forward, future research should delve deeper into the specific drivers of biodiversity pressures, including uncontrolled land conversion, extreme climate conditions, biophysical constraints, and anthropogenic and political factors. Moreover, efforts should be directed toward maintaining a green cover exceeding 30%, enhancing vegetation density, minimizing land-clearing activities, and encouraging the cultivation of crops with good water storage capabilities. This research lays the foundation for a more nuanced understanding of the intricate dynamics at play on small islands and sets the stage for informed conservation and management strategies.
