SCUAF
A Model to Estimate Soil Changes Under Agriculture, Agroforestry and Forestry

ABOUT SCUAF (version 5.0)

Access Help

SCUAF is a computer model which predicts the effects on soils of specific land-use systems under given environmental conditions. It is designed to include the distinctive features of agroforestry (land-use systems which include both trees and crops). SCUAF can also be used to simulate land use under agriculture or forestry, treating these as limiting cases of agroforestry (with either 0 or 100 percent trees replacing crops). This version of SCUAF uses Excel® to manage input and output files, so this software package must be available on your computer in order to run the model.

Development of this version of SCUAF was funded by the Australian Centre for International Agricultural Research (ACIAR) within a project entitled:"Economic potential of land-use change and forestry for carbon sequestration and poverty reduction".

Version 4 of SCUAF was published as an ACIAR Report by Anthony Young, Kenneth Menz, Peter Muraya and Chrysogon Smith. These help pages contain excerpts taken directly from that publication.

Version 5 of SCUAF represents a complete rewrite of the programming code. All the equations used in the original model were retained. However, the model was re-designed using an object-oriented approach to represent the complex interactions between soils, trees and crops in a more efficient and less error-prone way. A few minor errors found in version 4 were corrected.
