Abstract Land-use and land-cover (LULC) change detection plays a pivotal role in the sustainable management of natural resources, environmental monitoring, and the optimization of agricultural yields. Recent advancements in remote sensing and spatial analysis technologies have provided unprecedented opportunities to detect and model LULC Change detection with greater precision. This paper deals with random forest (RF) machine learning algorithm to detect the change detection, which shows promise in understanding and predicting LULC change dynamics. We explore the integration of novel data sources such as multispectral and hyperspectral imagery, LiDAR, and socio-economic datasets, enhancing the accuracy and contextual relevance of LULCC models. Despite these advancements, challenges persist in accurately modelling the complexities of land cover transitions, particularly in urban expansion and deforestation scenarios. The lack of comprehensive training datasets and the need for improved spatial-temporal resolution remain significant hurdles. This review emphasizes the importance of interdisciplinary approaches, combining ecological, hydrological, and socio-economic perspectives, to foster a holistic understanding of LULC change processes. We highlight the potential of emerging technologies and innovative algorithms to address these challenges and contribute to the development of resilient and adaptive land management strategies. Our findings underscore the transformative potential of machine learning in expanding the frontiers of LULC change research, paving the way for more informed decision-making in environmental conservation and sustainable development.

1. Related Work

   1. Advancements in Remote Sensing for LULC Detection

      Further, Zhu et al. (2021) focused on the integration of LiDAR and multispectral imagery to detect deforestation in tropical rainforests. Their results showed that LiDAR data significantly enhanced the ability to differentiate between forest and non-forest areas, especially in dense regions with varying canopy structures. This approach demonstrated the advantages of combining remote sensing platforms with complementary technologies to enhance land cover change detection.

   2. Machine Learning Applications in LULC Change Detection

      Machine learning, particularly the Random Forest (RF) algorithm, has been widely applied to LULC change detection. For instance, Bishaw et al. (2022) used RF for land cover classification in Ethiopia, incorporating time-series satellite imagery and socio-economic data to improve model predictions. Their results revealed that integrating socio- economic factors such as land tenure and agricultural policies could significantly enhance the predictive capability of LULCC models, especially in rural areas where land use is highly influenced by local policies and practices.

      Zhang et al. (2023) used RF to model land use transitions in urban areas of China. By combining high-resolution imagery from both the WorldView-2 satellite and socio-economic datasets, they achieved improved results in detecting complex urban land cover changes such as informal settlements and transportation networks. The study demonstrated the efficacy of RF in handling large-scale, multi-source datasets to model complex urban dynamics.

      Additionally, deep learning techniques such as convolutional neural networks (CNNs) have been explored to handle the high-dimensionality of hyperspectral imagery. Lee et al. (2021) applied CNNs to hyperspectral images for detecting forest cover changes in Southeast Asia, and their results showed that deep learning models outperformed traditional machine learning algorithms in capturing intricate spectral signatures, offering higher accuracy in detecting subtle changes like logging or vegetation health stress.

   3. Challenges in Modeling LULC Changes

      Despite the advancements in remote sensing and machine learning, several challenges persist in accurately modeling LULC change, especially in areas with rapid urbanization and deforestation. One of the key challenges is the lack of comprehensive and accurate training datasets, particularly in remote or under-sampled regions. For example, Yuan et al. (2020) highlighted the difficulty of obtaining high-quality training data in rural or inaccessible regions, which limits the effectiveness of machine learning models. The reliance on publicly available datasets often results in models that cannot capture the fine-scale variations in land cover types.

      Another significant challenge is the spatial-temporal resolution of satellite imagery. Kim et al. (2022) pointed out that the temporal gap between satellite observations can result in a failure to capture critical short-term land cover transitions, such as seasonal agricultural changes or sudden urban expansion. Improving the temporal resolution of remote

      sensing dta or developing advanced interpolation techniques is essential for overcoming this limitation.

   4. Integration of Socio-Economic and Environmental Data

      The integration of socio-economic data into LULCC models has been explored in several recent studies, reflecting the growing understanding that land use is driven by a complex mix of environmental, economic, and policy factors. For instance, Miller et al. (2023) incorporated data on population density, economic growth, and land tenure into their RF-based LULCC model for the African Savannah. The study concluded that socio-economic variables significantly enhanced the accuracy of predicting land use transitions, particularly in regions affected by political instability and rapid population growth.

      Similarly, Jiang et al. (2024) integrated hydrological models with remote sensing data to examine the impact of land cover changes on water resources in semi-arid regions. Their interdisciplinary approach demonstrated the importance of considering both ecological and socio-economic factors in LULCC models, providing a more comprehensive understanding of how land use changes impact broader environmental systems.

   5. Emerging Technologies in LULCC

   Recent research has also focused on integrating emerging technologies into LULCC detection. For example, Swenson et al. (2023) investigated the use of satellite-based synthetic aperture radar (SAR) to detect land cover changes related to deforestation and urban expansion in forested regions. SAR, with its ability to penetrate cloud cover and provide all-weather data, proved to be a promising tool for monitoring land cover changes in tropical regions, where cloud cover often limits optical remote sensing.

   Another area of innovation is the use of crowdsourced data and citizen science to complement remote sensing-based LULCC models. Johnson et al. (2024) used crowdsourced data from mobile applications to validate land use maps and help train machine learning models, particularly in urban areas where rapid changes occur. This citizen-driven approach provides an efficient and cost-effective way to collect ground truth data and enhance model performance.

   The period between 2020 and 2025 has seen significant advancements in remote sensing technologies, machine learning algorithms, and interdisciplinary approaches to LULC change detection. While challenges remain in obtaining high- quality training datasets and addressing issues of spatial- temporal resolution, the integration of novel data sources such as socio-economic datasets, LiDAR, and emerging technologies like SAR and crowdsourced data are paving the way for more accurate and contextually relevant models. These advancements are expected to further enhance decision-making processes in land management, environmental conservation, and sustainable development.
