Study "Estimation of land surface temperature and vegetation dryness index (TVDI) in Bac Binh - Binh Thuan using remote sensing images" aim to determine the progress of drought through the years in Bac Binh district - Binh Thuan province by using remote sensing images. In detail, we use images from Landsat 7 ETM+ (2002, 2005, 2010) and Landsat 8 OLI (2014 and 2017) to estimate dryness indices: temperature vegetation dryness index (TVDI) and improved temperature vegetation dryness index.

Ebook "Remote sensing of biosphere functioning (Ecological studies, Volume 79)" will rely heavily on the emerging technology of remote sensing from airborne vehicles, particularly satellites. Satellites offer the potential of continuously viewing large seg­ ments of the earth's surface, thus documenting the changes that are occur­ ring. The task, however, is not only to document global change, which will be an enormous job, but also to understand the significance of these changes to the biosphere. Effects on the biosphere may cover all spatial scales from global to local.

This article presents the results of applying geospatial technology to assess soil erosion for Yen Chau district. Geospatial Technology was applied to build maps of factors affecting soil erosion such as: rain erosion coefficient map (R), soil erosion resistance coefficient map (K), terrain erosion coefficient map (LS), cover erosion coefficient map (C) and farming practices (P). Improved universal soil loss equation (RUSLE) due to Wischmeier and Smith was used to create soil erosion maps.

Climate change and accelerating socioeconomic developments increasingly challenge environmental problems in the Vietnamese Mekong Delta (VMD) – a typical large, economically dynamic, and highly vulnerable delta. The amount of people exposed to climate changes in VMD is estimated to increase shortly. This paper collects information of the important discoveries about future climate changes from the global climate models (GCMs) indicating that VMD will likely be warmer in the future with an average temperature over 1.5o C and sea-level rise (SLR) will be 100cm in 2100s.

The normalized difference spectral index (NDSI) was used to determine significant wavebands that showed the best correlation with leaf ozone injury. The correlation coefficient (r) between NDSI and OIP were ranged from -0.79 to 1. Normalized difference spectral index, NDSI [R564,R568], and NDSI[R558,R573] were identified as the best Pearson’s correlation with leaf ozone injury percentage with correlation coefficient more than 0.96.
