Among landscapes, rural landscapes are important because they simultaneously present functional and cultural aspects. Rural often created to modify the Earth’s surface according different human needs and, among these modifying activities, terracing has significant anthropogenic effect. A multitemporal approach that covers a time interval is crucial for monitoring integrity value of historical l...
Rapid, accurate extraction of terraces from high-resolution images is great significance for promoting the application remote-sensing information in soil and water conservation planning monitoring. To solve problem how deep learning requires a large number labeled samples to achieve good accuracy, this article proposes an automatic identification method that can obtain high precision through sm...

Most of the current studies on soil conservation measures mainly focus their control effect, neglecting impact water quantity. In present study, latest seven years (2014–2020) monitored data from 22 runoff plots in upstream catchment Miyun Reservoir, Beijing were used to evaluate effects slope, rainfall, and loss, some implications given this water-scarce region. Excluding measures, loss increa...
In Zing LGA of Taraba State, the study evaluated farmers’ perceptions soil erosion and their conservation practices. To gather information for from farmers farmland, field observation, informal interviews, use research instruments including questionnaires remotely sensed imageries were all used. These data analyzed in a Windows GIS context using SPSS 23. The results indicate that 68% respondent...
nowadays soil erosion is considered as a serious threat to human's life and his welfare. when soil erosion not properly controlled, the fertility would gradually decrease. adoption of appropriate soil conservation practices along with socio-economic factors' assessment can be used to increase farmers' awareness and acceptance of soil conservation, and to diminish soil erosion dam...
Soil erosion by water is commonly recognized as the one of main reasons of land degradation worldwide (e.g. Ananda & Herath, 2003; Beskow et al., 2009; Valentin et al., 2005). Most of the involved areas are occupied by various agricultural activities but pastures, forestry, unpaved roads as well as construction sites are also endangered by water erosion (Ananda & Herath, 2003; Arnanez et al., 2...
North Bandung area covering structural landforms and volcanoes has an active volcano fault, leading to potential of landslide. This study aims create a new scheme LULC zones based on landslide prone area. The zone is analyzed through Fuzzy the following variables: rainfall, drainage distance, density, slope angle, aspect, distance lineament, elevation, curvature, topographic wetness index (TWI)...
Electron transporting (n-channel) polymer semiconductors for field-effect transistors are rare. In this investigation, the synthesis and characterization of new electron-depleted N-alkyl-2,2'-bithiophene-3,3'-dicarboximide-based pi-conjugated homopolymers and copolymers containing the 2,2'-bithiophene unit are reported. A novel design approach is employed using computational modeling to identif...
