The issue of the land degradation vulnerability index (LDVI) is multifaceted, encompassing climate, soil, vegetation, policy formulation, and human actions. In Vietnam, convergence climatic fluctuations impact results in phenomena, such as soil sealing, erosion, salinization, landscape fragmentation. These phenomena are recognized significant triggers degradation. This paper seeks to present a method for assessing land's susceptibility by utilizing ten ecological 10 criteria: NDVI; slope;...

The suitability of land for C. konishii was evaluated using the analytic hierarchy process (AHP) method, which included multiple criteria, such as elevation, soil, climate, and vegetation characteristics. 120 different sites were studied model approximations verified by a confusion matrix. subsistence mainly affected topographic features (elevation, slope) soil (soil texture) conditions. 15 variables selected ecological analysis construction map. They combined into four main groups weights...

The process of urbanization in Vietnam is developing rapidly, corresponding to the rapid changes land use. Forecasting use development assists policymakers making accurate decisions urban planning and development. objective this paper forecast analyze trends based on Landsat images 2006, 2010, 2016 with help remote sensing GIS, a case study at Gio Linh district, Quang Tri province. analysis results show that district has led decrease forest area from 28.14% compared total area, 13.5%, 2026...

Impervious surface is artificial surfaces that prevent water from entering the soil. The increase in impervious area has led to negative impacts on urban environment, including an risk of flooding, a decrease vegetation cover, and formation heat islands. This paper presents results building predictive model Hochiminh city remote sensing GIS data. Landsat Sentinel 2 satellite images for period 2002–2022 are used classify extract input layers about land temperature, combined with data...

The landscapes in the Hinh River Basin are crucial and highly sensitive to climate change for coastal province of Phu Yen entire south-central region Vietnam, offering vital environmental services its downstream areas. has a rich system rivers streams abundant surface water resources. However, it remains one region's top localities at risk very vulnerable region. This study aims evaluate changes landscape (LC) over 10 years (2010-2023) predict LC next six using machine-learning (ML)...

Vietnam is a country with rich mineral resources, of which coal reserves are about 8.6 billion tons, concentrated mainly in the basin Quang Ninh province. Besides economic and social benefits, mining has negative impacts on environment, such as air water pollution. Air pollution areas seriously affects human health environment. This study presents results mapping quarterly spatial distribution maps pollutants province, including CO, NO2, O3 SO2 from Sentinel 5P TROPOMI data. data four...

The topography of the earth's surface can be represented in GIS by DEM data. Surface modeling is process determining natural or artificial surfaces using one more mathematical equations. A general algorithm for all applications not available, each method creating a topographic has several advantages, disadvantages and depends on its processing direction. As such, experimenting, evaluating selecting algorithms that are appropriate to reality data research area necessary. Research paper,...

The research aimed to evaluate the land potential for annual and perennial agricultural crops in Song Hinh district - Phu Yen province of Vietnam using integration AHP -GIS technique based on maximum limitation method FAO (Food Agriculture Organization United Nations) ecological requirements planted rubber plant cassava ( Hevea brasiliensis Manihot esculenta ). Twenty social, economic environmental parameters selected analyze model. results evaluation showed that high is likely increase by...

The present study was aimed to determine the potential cultivated lands for rice crop production in Vietnam. Analytic Hierarchy Process (AHP) and Technique Order of Preference by Similarity Ideal Solution (TQPSIS) were employed order analyze structure an ideal solution agriculture that focuses mainly on environmental, economic, social sustainability. A final ranking alternative development solutions also accomplished. Three major factors taken into consideration during process, including...

Ta Dung Nature park is an important ecological region, its buffer zone currently has coffee as the main crop. However, declines in yields result a relative reduction spending power by households. This study aimed to assess land potential proposal for cultivation. Sustainable agriculture must nurture healthy ecosystems and support sustainable management of natural resources. An approach based on integrated use Analytical Hierarchy ProcessGeographic Information Systems Remote Sensing...

The objective of present study was to assess the physical land capacity for an annual cassava crop, aiming understanding spatial parameters and environment required locating potential areas cultivation. According FAO guidelines, a model built facilitating sustainable production through integration AHP-GIS-Remote Sensing method. showed that analysis indicated high 6101.1 ha (8% total area), concentrated in middle eastern part area. These face limitations cultivation due climatic conditions...

Illegal mining, including the violation of lease boundaries during extraction mineral deposits in Vietnam, has witnessed a significant surge recent years, leading to substantial environmental degradation. Due remote locations mining areas relation settlements, detection illegal activities using conventional methods poses considerable challenges. This study presents methodology for identifying boundary violations open-pit by utilizing high-resolution satellite images from Sentinel-2 MSI...

Rainfall is one of the crucial data types in meteorological research. In context increasingly complex climate change, forecast essential for modeling and predicting natural disasters, especially floods landslides. To ensure accuracy rainfall prediction cost building operating rain gauge stations, determining number stations crucial. Therefore, this study developed an optimization design station network Da Rang River focusing on quantity spatial distribution stations. The geostatistical...

Human resources is the decisive factor determining quality of training universities. Especially in context international integration and explosion fourth industrial revolution (revolution 4.0) today, order to survive, develop assert their brands, universities must pay more attention human meet increasing demands society. In recent years, Vietnam has been continuously improved. However, compared with developed countries region, Vietnamese still limited, a long distance, requiring longer-term...

The main aim of present study was to determine the most suitable land for paddy via AHP - GIS and Remote Sensing. Ba Thuoc district Thanh Hoa province selected as target area conduct experimental set-up. As per opinion scientists guidance World Food Organization (FAO) on agricultural crops, criteria estimate ecological adaptation crops include soil type, texture, depth, pH, N (%), elevation, slope, distance from rivers, yearly precipitation, low-average high temperature, average sunny hours,...
