Summary: This study analyzed the changes in land use and land cover in Guwahati city, northeast India from 1995 to 2020 and their impact on land surface temperature and the urban heat island phenomenon. The results showed a significant increase in built-up land and a decrease in vegetation and cropland. The future simulation predicted a continuous increase in built-up land. The seasonal land surface temperature predictions indicated that more areas would face higher temperatures in both summer and winter.

Summary: Building height serves as an important feature of urban morphology and can provide insights into human socio-cultural behaviors and their impact on the environment. However, there is a lack of openly accessible individual building height information. This study proposes a method for extracting urban building height using ICESat-2 ATL03 photons and high-resolution remote sensing images. The results show that the proposed method can accurately extract building heights with a Mean Absolute Error (MAE) of 4.7 m, outperforming traditional shadow-based and offset-based methods. The proposed method is considered a good candidate for accurately retrieving building heights on a city-wide scale.

Summary: Rill erosion on unpaved roads is a significant problem on the Loess Plateau in China, but there is limited research on its evolution mechanism. In this study, a runoff scour experiment was conducted on an abandoned field road using a terrestrial laser scanner to assess the dynamic evolution of rill erosion and fill. The results showed that soil erosion significantly decreased after the initial surge, and the downstream was characterized by fill rather than erosion. The relationship between slope, erosion, and fill varied for each scouring.

Summary: Recently, there has been a focus on environmental stewardship of mangroves due to their ability to protect coastal regions, sequester carbon dioxide, and provide various ecosystem services. A participatory stakeholder assessment was conducted to assess drivers of mangrove loss in Odisha, India, using a mixed-method approach. The study found that increased frequency of extreme climatic events, aquaculture, and land-use changes were potential drivers of mangrove loss. Developing future scenarios that incorporate the concerns of all stakeholders and implementing interactive governance and incentivization approaches were suggested as potential solutions for conservation and restoration in the region.

Summary: River bankline migration is a common occurrence in floodplain regions, and changes in land use and land cover associated with channel dynamics pose a risk to nearby residents. This study assesses the changes in the Brahmaputra River's planform and relates it to changing land use. The erosion-accretion rate was found to be higher in early times than in recent years, and the left bank had more erosion than the right. The results help inform hazard management strategies for the Brahmaputra River.

Summary: Ground shaking on steep slopes triggers landslides and affects vegetation dynamics. This study used pre-and post-earthquake DEMs and remote sensing images to analyze the topographic changes, post-seismic landslides, and vegetation recovery after the 2004 Chuetsu earthquake in Japan. The findings show that the earthquake steepens and roughens the terrain, alters slope aspects, and causes vegetation damage. However, the vegetation has shown a recovery rate, and the number of active landslides has decreased over time, indicating a stable hillslope in the future.

Summary: The alteration of land use and land cover caused by human activities has had a notable impact on ecosystem services at regional and global levels. In this study, we estimated and showed the spatio-temporal variation of ecosystem service values in a small freshwater wetland in India from 1990 to 2040. The results indicated an increase in built-up areas and agricultural land, as well as a decrease in open water and vegetation cover, leading to an ecological imbalance in the study site. Protecting the natural ecosystem should be prioritized in future land-use planning.

Summary: The 2004 Indian Ocean earthquake and tsunami had a significant impact on the coastal shoreline of the Andaman and Nicobar Islands, causing extensive destruction of infrastructure and ecological damage. This study analyzes the short- and long-term changes in the South Andaman shoreline, focusing on the pre- and post-tsunami period of 2004-2005 and the period of 1990-2023 to assess periodic changes. Remote sensing techniques and geospatial tools were used to calculate shoreline change rates in four zones, revealing the extent of the tsunami's impact. The results demonstrate the extensive impact of the tsunami on the coastal shoreline of South Andaman and the value of analyzing shoreline changes in understanding the consequences of such events on coastal ecosystems.

Summary: In this study, electrical resistivity tomography and photography techniques were proposed to monitor and verify water percolation in soil in real-time. The experimental results showed that the low-resistivity anomalies in the electrical resistivity profiles corresponded well with the wetting areas captured in the photographs. Therefore, ERT and photography techniques can be applied simultaneously for the monitoring and verification of water percolation.
