To solve territorial arrangement and alternative land use allocation,
a heuristic alogorithm was used. The study area included 2216 hectares
located in the Andes range, Panguipulli, 10th Region, Chile. To
solve the problem, a links and nodes network was established. The
nodes represented multiple products from different productive units,
time periods and destinations. The links represented fixed and variable
transportation and operational cost and investments and unit revenues
from each alternative use. The analysis considered the following
alternative uses; wood products from native forest, non-use value
of native forest as carbon stock and conservation or existence value.
Cattle, crop farming and Pseudotzuga menziesii plantations are considered
for areas without vegetation or covered with bushes. The solution
chooses the most efficient use, the path and the destination for
multiple time periods maximizing the net present value. Native forest
areas allocate productive forest use when the wood net benefits
exceed the net present value as carbon stock. The current areas
without forest are recommended as cattle and Pseudotsuga menziesii
plantations over wheat cultures depending on terrain conditions.
This work proves that the methodological tool proposed, selects
uses to maximize the total net present profits, reaching an efficient
solution that could be extended to solve similar or more complex
problems which include different uses and wider territoral areas.
