Preventive and curative measures to reduce land desertification were investigated in four communities in Osun State. Watershed management was adopted for four farms where such adopted processes like agri-silvipasture, agri-horti-silviculture and agroforestry were practiced. Each of the existing farms that were researched into where these practices were available was an hectare. Agri-silvipasture was adopted in two communities, each as agri-silviculture and silvi-pastoral system. Surface water from the lands were drained into a well-designed triangular waterway, each for a plot of an adopted practice. Cocoa trees, maize, palm trees and teak farm plots were used. Among the parameters measured/calculated were the velocities of flow, v; discharge, Q and maize yield. One-way analysis of variance was used for statistical analysis with means separation by Duncan multiple range tests. It was found out that scouring of the soil particles in the channel occurred from the upper course to the middle and then extended to the lower portion of the waterway with highest flow velocity of 0.945m/s and the lowest of 0.574m/s. The mean were 0.846±0.122 for the flow velocity and 7.428±0.588 for the discharge in the agric-silvipasture system (SPC) treatment. Watershed land had ability to support the use of various adopted development to reduce their erosivity indices, manage the environmental watershed to provide more water for agriculture.
