Event Title
Concurrent Session 3 Modelling Soil Erosion Using the Revised Universal Soil Equation Model (RUSLE) in Anambra, Nigeria
Start Date
21-4-2022 4:20 PM
Description
Soil erosion is a major environmental problem ravaging Anambra, Nigeria. The soil loss was assessed via a RUSLE Model integrated into a GIS environment. The annual soil loss in the area ranges from 0 to over 5000 tha-1yr-1 with an annual mean of 18.9 tha-1yr-1. It shows that severe erosion occurs in the central, southern and eastern parts of the area. The areas within the tolerable erosion rates are about 65.64% (3179.6 km2) of the area while about 28.03% (1357.77 km2) is under extreme soil erosion. However, there are very wide variations in the soil erosion across the area with a standard deviation of 88.6 tha-1yr-1. Thus, the severe soil degradation going on in the area calls for immediate and sustainable intervention to conserve the soil.
