“…The C factor represents the relationship between erosion on bare land and erosion on cultivated land [41] whereas the P factor represents the consequences of soil protection measures such as contouring and terracing [12]. The C and P values were assigned as per the land uses in the vector format [42][43][44][45] (Table 3) and converted to raster format to be used with other factor layers.…”

Soil erosion is a global environmental threat, and Land Use Land Cover Changes (LUCC) have significant impacts on it. Nepal, being a mountainous country, has significant soil erosion issues. To examine the effects of LUCC on water erosion, we studied the LUCC in Sarada, Rapti and Thuli Bheri river basins of Nepal during the 1995-2015 period using the Remote Sensing. We calculated the average annual soil loss using the Revised Universal Soil Loss Equation and Geographical Information System. Our results suggest that an increase in the agricultural lands at the expense of bare lands and forests escalated the soil erosion through the years; rates being 5.35, 5.47 and 6.03 t/ha/year in 1995, 2007 and 2015, respectively. Of the different land uses, agricultural land experienced the most erosion, whereas the forests experienced the least erosion. Agricultural lands, particularly those on the steeper slopes, were severely degraded and needed urgent soil and water conservation measures. Our study confirms that the long term LUCC has considerable impacts on soil loss, and these results can be implemented in similar river basins in other parts of the country.

“…The change in the land use will respond differently to the soil erosion due to monsoon rainfall (Santos et al, 2017;Zare et al, 2017). Radish, potato, and cabbage crop fields are more vulnerable to soil runoff during the heavy rainfall period than the rice paddy and gin- ) estimated for selected major crops with growing characteristics in the Haean basin.…”

This study examined the relationship between the land-use and land-cover changes in the mountainous Haean Basin of the Republic of Korea, a water source area, and the muddy water in the downgradient. The water flowing out from the basin is highly turbid having value of 650.1 Nephelometric Turbidity Unit (NTU), while that from the upper Inbuk Stream lacking major crop fields is very clean (less than 1 NTU), indicating agricultural activities as the origin of the turbid water. Among the six major crops in the cultivated area, rice prevails the maximum area (31.5-51.5%, mean = 38.7%), followed by radish (0.2-32.4%, mean = 20.1%) and potato (9.4-32.2%, mean = 19.4%). The mean annual soil erosion (t ha-1 yr-1) from major crops; radish (55.6), potato (53.0), cabbage (47.9), soybean (40.3), ginseng (23.6), orchard (18.7), and rice (1.3) contributed to water turbidity, differently. Avoiding the cultivation of radish crop can help to reduce overall rate of soil erosion from the basin. Proper maintenance of mitigation measures would result in minimal soil erosion and reduced water turbidity.

“…De modo más específico, en lo que atañe a la erosión del suelo, las imágenes Landsat han posibilitado el desarrollo de estudios de tipo cualitativo, cuantitativo, simuladores de riesgo de erosión y caracterizadores de la ocupación del suelo, como insumo a los modelos USLE o RUSLE (Buendía-Rodríguez et al, 2008;Drzewiecki et al, 2014;Bernabe et al, 2015;Oliveira et al, 2015;Zare et al, 2017). Otros productos de sensores remotos, como las imágenes SPOT, han sido también utilizadas para estudios de la erosión; un ejemplo es la determinación de la susceptibilidad a deslizamientos desarrollado por Pineda et al (2016).…”

Este documento presenta una perspectiva general del estado actual del conocimiento de la degradacion del suelo por la erosion hidrica, con enfasis en su evaluacion y representacion cartografica. Se incluyen fundamentos y aspectos historicos de mayor relevancia y se explican las diversas categorias metodologicas empleadas en su estudio y evaluacion, con algunas experiencias de aplicacion. Se destaca la importancia del uso de los sensores remotos y los Sistemas de Informacion Geografica (SIG). Sobre los primeros se discute el uso de las imagenes satelitales, de importante apoyo cualitativo y cuantitativo para investigaciones y evaluaciones de los procesos de erosion, modalidades que permiten visualizar y hacer un seguimiento de dichos procesos en tiempo y espacio. Respecto a los SIG, se evidencian sus limitaciones y potencialidades dada su gran capacidad de representacion cartografica, analisis y ahorro de tiempo. Los SIG han permitido facilitar procesos laboriosos vinculados a la representacion cartografica producto de los estudios comunmente relacionados al tipo, condicion, riesgos actuales y potenciales de la erosion hidrica, mapeados a diferentes escalas.
