Evaluation of natural resources depletion in Indonesia: a natural resource accounting approach
1994
Warsito, S.P.
Applying the approach showed that net addition in terms of area and volume of the forest resource in islands outside Java was found negative during 1968-1990. The major causes of the depletion were more due to deforestation, rather than logging. For plantation forest in Java, no change in terms of forest area stock was found, but change was noted in forested area. However, the volume of the standing stocks shows positive net changes during 1976-1990, due to its depletion (harvest etc.) which was less than the forest stand growth. The forest timber stand of the plantation forest was dominated by the younger age classes (immature timber stand) which tends to provide higher growth than its depletion. The depletion of petroleum resource appeared relatively balanced with its discoveries during 1970-1990. However, without new discoveries henceforth, this resource may be completely exhausted by 2010. Negative changes in the total natural resource accounts were detected through economic accounts using price method (NPM) during 1983-1990. However, using asset value approach (AVA) the negative changes were accured only during 1983-1985 in the accounting period, due to the inclusion of the predicted future income gained from these two natural resources. Integrating such charges into the national accounts showed that using net price method, the net national income (NNI) and net domestic investment (NDI) were positive but lower than that calculated using the conventional method. Excluding petroleum discoveries from the accounts tends to emphasize that all incomes gained from natural resource extractions were used more to finance domestic investments rather than current consumption
