Livestock numbers and land-use demands were computed for each of these scenarios.
Each of the four scenarios above was also examined under two sets of conditions
concerning urban growth. One option, labelled ‘a’, preserves the ALR so that no urban
development can take place in the ALR. The other option, labelled ‘b’, considers effects of
not preserving the ALR and allowing urban development to take place within the ALR.
Thus, in all, eight scenarios were examined for their effects on environmental and
economic systems.
