DESCRIPTION:Erosion is a major environmental threat that has a negative imp
 act on agriculture and ecosystems. In the region of Dudh Koshi\, in Nepal\
 , soil erosion is taking place at a high rate\, causing a serious concern 
 for the fertility of agricultural lands. This region of Nepal relies on a 
 subsistence farming system\, therefore a reduction in the fertility of lan
 ds could cause a threat to the food security of the population inhabiting 
 this mountain area. Some study have been conducted in order to estimate th
 e rate of soil erosion\, for this area of the world\, in the present and r
 ecently passed decades\, but the study proposed in this works aims at esti
 mating the future trends of soil erosion rates\, until 2100\, in order to 
 detect the values of increment in soil loss and the areas that will face t
 he worst cases. To achieve this goal the two parameter of the D-RUSLE mode
 l\, that change with the time\, were considered: precipitation (R-Factor) 
 and land cover (C-Factor). As far as the R-factor is concerned\, different
  scenarios of climate change have been considered: eight combination of Gl
 obal Circulation Model (GCM) under Representative Concentration Pathway (R
 CP). To perform this analysis data from Himalayan Adaptation\, Water and R
 esilience (HI-AWARE) were used. To evaluate the future evolution of the C-
 Factor a neural network was trained using two different land cover maps\, 
 representing the situation in 1990 and 2010. The land cover maps were prov
 ided by International Center for Integrated Mountain Development (ICIMOD).
