Abstract:
The purpose of this paper is to illustrate the use of Linear Programming (LP) and
other mathematical procedures to evaluate watershed and perpetuity constraints on forest
land use for a selected scenario in Terengganu, Peninsular Malaysia. The paper describes
the system of modelling and forecasting estimates of potential timber growth, forest
harvest and inventory for use in planning with environmental considerations. The LP
model provided a range of feasible solutions for decision making. Equations were
derived for the model to show interaction of sedimentation due to road construction,
timber harvesting, and other related forest management activities.
Sensitivity analysis was used to test model behavior. A literature review provided
information to supplement the findings gathered from simulation of the linear
programming problem. The model further evaluated using theoretical, mathematical and
observational procedures. Results indicate the constraining effects of sedimentation upon
forest revenues when sedimentation is allowed to vary within the feasible region of the
model (i.e., from 600,000 m3/decade up to 1,150,000 m3/decade.
