( Class -4 ) Answer of Soil erosion has increased in the last century? How does this affect
us?
Answers
Answer:
soil erosion has been considered as the primary cause of soil degradation because soil erosion leads to the loss of topsoil and soil organic matter, which are essential for the growing of plants. Quantification of soil loss is a significant issue for soil and water conservation practitioners and policy makers. This chapter presents a comprehensive methodology that integrates the Soil and Water Assessment Tool (SWAT) with a geographical information system (GIS) for simulating soil erosion risk within a small mountainous watershed that is an upstream area of the Bo River watershed in Central Vietnam. The spatial patterns of annual soil erosion rate from 2000 to 2010 were obtained. The results found that the largest amount of soil erosion was 92.33 ton ha− 1 in 2007, followed by 2010 (85.41 ton ha− 1) and 2005 (76.79 ton ha− 1). The average amount of soil erosion from 2000 to 2010 was 62.50 ton ha− 1, which causes high risk in threatening land resource of the whole watershed considerably. Additionally, the resultant maps of annual soil erosion show a maximum soil loss of 153.48 ton ha–1 year–1 with a close relation to dry agriculture land areas on the slopes higher than 25%. The spatial erosion maps generated with SWAT and GIS can serve as effective inputs in deriving strategies for land-use planning and management in the environmentally sensitive
