Summary: The study analyzed the temporal and spatial changes in China's mangrove landscape pattern, finding that before 2000, each shore exhibited a downward trend in total area, deteriorating connectivity, and stable fragmentation at a low level. After 2000, although the total area improved, fragmentation gradually increased. Shores in Guangdong and Hainan showed significant differences within the same province.

Summary: The study projected the trend of land-use and landscape changes for 2030 by analyzing remote sensing data and different periods of landscape analysis. The results showed significant degradation of rangelands and forests due to conversion to agriculture and construction, as well as a declining trend of lakes' water bodies. The increase in agricultural lands and overuse of groundwater wells upstream of lakes are considered factors contributing to these changes, posing a severe threat to human health and ecosystem services.

Summary: A remote sensing-derived lake ice phenology database covering all lakes in Alaska from 2000 to 2019 was constructed to analyze the trends of earlier breakup and later freezeup of lake ice in the region. The dataset showed significant trends towards earlier or later ice breakup and freezeup for various lakes, with most significant trends observed in lakes north of the Brooks Range. This dataset contributes to the understanding of interactions between lake processes and climate change, supporting research on biogeochemical, limnological, and ecological regimes in Alaska and pan-Arctic regions.

Summary: The study successfully quantified groundwater storage changes in California's Central Valley using remote sensing data and a water balance method. The estimates correlated well with independent sources and reliably captured long-term trends, seasonality, and groundwater depletion rates during droughts. The method also has the potential to estimate sub-annual changes in groundwater, providing valuable insights for regional water management during drought events.

Summary: The number and area of alpine lakes in Tien Shan are rapidly growing, mainly due to a warming climate and retreating glaciers. Glacial lakes continuously increased in size, while non-glacial lakes expanded intermittently. Proglacial lakes and extraglacial lakes showed the highest expansion rates among the four types of alpine lakes.

Summary: The study aimed to analyze the seasonal concentration, groundwater quality, usage areas, and arsenic-related health risks in the Salda Lake basin. The findings indicated that the water quality was mostly good, but arsenic had potentially harmful effects in the study area, especially in non-carcinogenic and carcinogenic aspects. Monitoring the groundwater quality and determining appropriate usage areas is crucial based on the results obtained.

Summary: A conceptual model of the geothermal system in Konya province was established based on water samples from ten geothermal fields, identifying reservoir rocks, heating sources, the composition of thermal waters, and their connections with different types of rocks. The presence of high chloride in the thermal waters indicates a direct link with the deep geothermal system, while sulphate originates from the dissolution and oxidation of minerals.

Summary: In this study, groundwater vulnerability assessment was conducted for the Burdur Saline Lake basin in SW Turkey using the DRASTIC model, fuzzy AHP, and GIS integration. Validation and sensitivity analyses were performed, and the most effective parameters were determined. The obtained vulnerability map was confirmed by nitrate concentrations in the groundwater. Urgent protection measures are recommended for highly vulnerable areas to ensure sustainable use of groundwater.

Summary: Floods are a common natural disaster worldwide, and their risk is expected to increase due to global climate change. To minimize flood risk, regional flood risk maps should be created and hydraulic modeling studies should be conducted. This study assessed flood risk potential in the Kucuk Aksu Basin, a sub-basin of the Antalya Basin in Turkey. Various parameters such as slope, rainfall, land use, and soil type were used to define flood risk, and a geographical information system-based analytical hierarchy process was used to prioritize these parameters. The results showed a significant flood risk in the study area, especially in settlement and agricultural areas, highlighting the need for improved land-use planning.

Summary: This study evaluated the heavy metal pollution in Beys,ehir Lake, the largest freshwater lake in Turkey. The concentrations of heavy metals in lake water and sediment samples were determined, and various index methods were applied. The results showed that the heavy metal concentrations in lake waters were below the limit values and suitable for drinking water. The risk of heavy metal contamination in lake sediments was also low.

Summary: The study investigated groundwater quality and heavy metal pollution in the Eber wetland area in Turkey. It found that nitrate pollution was present due to agricultural activities, but the heavy metal pollution was within acceptable limits for drinking water. However, a health risk assessment revealed that the levels of arsenic exceeded tolerable values, indicating that the groundwater should not be used as drinking water.

Summary: Uluabat Lake, one of our country's essential Ramsar areas, is facing significant pressure from environmental pollutants, particularly heavy metal pollution. This study used GIS-based index methods to examine the heavy metal pollution and water quality in the lake. The results revealed that the concentration of As in the lake water exceeded the limit value, making it unsuitable for drinking. However, other metal concentrations were below the specified limit values. Overall, the lake water samples were suitable for drinking water use according to index calculations, but As was moderately contaminated. The enrichment of As, Cr, Ni, Pb, and Cd in lake sediments indicated the impact of anthropogenic pollutants and a decline in sediment quality. The study concluded that environmental pollutants, especially heavy metal pollution, primarily enter the lake water through stream transports, leading to pollution in Uluabat Lake.
