What is the relationship between lst dan lulc?5 answersThe relationship between Land Surface Temperature (LST) and Land Use Land Cover (LULC) is well-established in various studies. Changes in LULC, such as urban sprawl and vegetation loss, have a direct impact on LST, leading to phenomena like Urban Heat Islands (UHI). Studies have shown that built-up areas experience higher LST compared to other land types, while vegetation areas exhibit the lowest LST levels. The correlation between LULC and LST has been analyzed using satellite data and GIS algorithms, highlighting the significant increase in impervious surfaces and decrease in natural green areas over the years, contributing to rising LST levels. By utilizing explainable artificial intelligence models, researchers have been able to predict LST changes following specific LULC modifications, emphasizing the importance of urban planning and green spaces in mitigating LST impacts.
What is land use and land cover?5 answersLand use refers to how people utilize land, such as for agriculture or conservation, while land cover pertains to the physical attributes of the land, like vegetation or water. Changes in land use and land cover have significant impacts on environmental and socioeconomic sustainability, necessitating detailed mapping and monitoring efforts using high-resolution satellite images and advanced digital processing techniques. The assessment of land use cover's influence on river water quality is crucial for effective river basin planning and management, especially in mitigating non-point source contamination from agricultural watersheds. Various methods, including digital change detection and classification calculations, are employed to study land use/land cover changes, with deep learning algorithms proving to be effective for predicting such changes.
What is LULC Change?4 answersLand Use and Land Cover (LULC) change refers to alterations in the way land is utilized and the vegetation or structures covering it. It is a crucial aspect impacting hydrology, ecological systems, climate change, and urban development. Various studies have utilized techniques like machine learning, remote sensing, and Geographic Information Systems (GIS) to monitor and analyze LULC changes over time. These changes can include transitions from natural areas like forests and agricultural land to built-up areas due to factors such as urbanization, population growth, and infrastructure development. Understanding LULC changes is essential for sustainable resource management, effective urban planning, and achieving conservation goals.
What is LULC?4 answersLand Use and Land Cover (LULC) refers to the classification and mapping of different types of land and their covers. It is an important aspect of environmental management, decision-making, and urban planning. LULC maps provide information about the distribution and changes in land use and land cover over time. They are created using satellite images and remote sensing techniques, along with machine learning classifiers and geographic information systems (GIS). LULC monitoring helps in understanding urbanization, agricultural land changes, and their impact on sustainable development goals. Accurate LULC maps are crucial for making informed decisions related to policies, environmental conditions, and land control. Various methods, such as random forest classification, spectral vegetation indices, and deep learning models, are used to improve the accuracy and efficiency of LULC mapping.
How has highway expansion been associated with land use/land cover (LULC) shifts?5 answersHighway expansion has been associated with shifts in land use/land cover (LULC) patterns. Studies have shown that the construction or expansion of highways increases the probability of new industrial and commercial buildings being constructed in the surrounding areas, even when there are legal constraints and laws in place to limit such development. This indicates that highway access provides incentives for the conversion of vacant land into built areas, leading to changes in LULC. Additionally, the expansion of highways has been found to have environmental implications, such as changes in land surface temperature (LST) and vegetation loss. These findings highlight the need for considering the impact of highway infrastructure on LULC and the environment in urban planning and management.
Why we have need to study lulc and lst?5 answersThe study of Land Use Land Cover (LULC) and Land Surface Temperature (LST) is important because human activities have led to significant changes in the natural landscape, particularly through LULC changes induced by urbanization and development. These changes have direct impacts on LST, leading to phenomena such as urban heat islands (UHI). Understanding the relationship between LULC and LST can help in assessing and monitoring the thermal environmental impact of urban planning and projects. It can also aid in identifying areas that require attention and developing strategies for sustainable city development. Previous studies have utilized various approaches, including regression models and artificial intelligence, to examine this relationship. By analyzing satellite data and using GIS algorithms, researchers have found that built-up areas experience higher LST compared to other land types, while vegetation land has the lowest LST. Overall, studying LULC and LST provides valuable insights into the environmental and climate changes induced by human activities and helps in developing strategies to mitigate their impacts.
