Evaluation
Matrix for ASB "Best
Bet" and Reference
Land Use Systems
A
matrix approach
was adopted to evaluate
these potential
best bet alternatives,
as shown in Table
1. The columns of
this matrix depict
the groups of indicators
selected to represent
the global environmental,
national policy,
and local farmer
economic and agronomic
concerns. Using
this matrix, tradeoffs
among the different
indicators can be
assessed and policy
makers can compare
and contrast the
potential outcomes
and impacts of policy
scenarios on land
use dynamics
