The paper "A novel approach of neural networks and USLE in smart soil erosion modeling, case study in Southern coastal of Viet Nam" adopted one of the neural networks - the Long ShortTerm Memory (LSTM) to analyze temporal variations in erosion patterns over time, aiding in understanding erosion dynamics. Furthermore, another common soil erosion model - the Universal Soil Loss Equation (USLE) was investigated to predict annual soil loss. Our data were extracted from remotely sensed data (DEM - Digital Elevation Model and MODIS) and vector data of the study area.

Erosion is an environmental phenomenon, but due to human activities this phenomenon has led to many serious problems. With the aim of protecting soil resource, as well as circumscribe damages by erosion, so the study of applying USLE on assessing soil erosion at Lam Son headwater catchment was conducted. To reach the purposes, the content of the study focus on collecting data and using USLE, ArcGis software to form rainfall map, slope coefficient and slope length map, canopy cover coefficient map.

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.

Soil erosion is a naturally occurring process in mountainous areas that affects all landforms. Located in Central of Vietnam, in the tropical monsoon climate Da Nang City is characterized by more than 70 percentage of area with hilly and mountainous topography. This study is objective apply the Universal Soil Loss Equation (ULSE) model developed by Wischmeier and Smith (1978) integrating with remote sensing data and Geographical Information System (GIS) tool to evaluate soil erosion risk in Da Nang City, Vietnam.

This study investigates the spatial pattern of soil erosion risk and map the annual soil loss rate in the Upper Beles watershed of the Blue Nile Basin, Ethiopia. The Revised Universal Soil Loss Equation (RUSLE) model, coupled with geographical information system (GIS), has been adopted for soil loss estimation.

Soil erosion depletes the productive layer of soil which is an ultimate resource for all agricultural activities. Since erosion rate varies with watershed characteristics, a study of soil and water dynamics at a watershed level can facilitate a scientific approach toward their conservation and management. The study involves obtaining peak runoff and input parameters (K,LS,C & P) of Modified Universal Soil Loss Equation (MUSLE) integrating GIS platform to estimate soil loss...

Soil loss was estimated from agricultural lands of South Andaman district in tropical Bay Islands applying Universal Soil Loss Equation (USLE). Mean annual rate of soil loss to the tune of 184.1 X 103 tons was estimated from the crop fields of the district covering 1747.0 ha area at the rate of 105.38 t ha-1 yr-1 . In South Andaman district, kharif crops (rice, maize, arhar, ground nut, ginger, sweet potato, tapioca and turmeric) are grown in medium to low lands whereas rabi crops (pulses and vegetables) are grown in uplands. The cropping intensity is 104.0%. Maximum (136.

We conducted 20 plots & 80 random points to collect data. To assess soil erosion, the study was based on IDW interpolation in ArcGIS to conduct maps. The results show that (1) There are five main forest types (Pine, mixed Pine and Acacia, Acacia, Eucalypt, mixed Eucalypt & Acacia) in which Pine (Pinus merkusii) is a native species and dominant in protection plantations with 47.65% (665.96 ha).

Abiotic stresses are serious threats to agriculture and the environment which have been exa‐ cerbated in the current century by global warming and industrialization. According to FAO statistics, more than 800 million hectares of land throughout the world are currently salt-af‐ fected, including both saline and sodic soils equating to more than 6% of the world’s total land area. Continuing salinization of arable land is expected to have overwhelming global impact, resulting in a 30% loss of agricultural land over the next 25 years and up to 50% loss by 2050.
