Economische gevolgtrekkingen, voortvloeiende uit een analyse van den djati-opstand en van het djati-boschbedrijf op Java

Beekman, H.A.J.M.
Beekman tried to define the financial rotation of teak high forest in a clearance felling system, allowing for modifying factors. For practical reasons only one site of quality (IV) in one forest district was considered. This district had been used for timber production for 20 years. Through its favourable situation and therefore favourable marketing and ease of transport, and smooth labour relations, the yield of timber had been increased more than anywhere else in Java. These conditions were taken as an ideal standard.He tried to assess the stand value, the value of the normal wood stock, the forest value and the internal rate of return. For this purpose first the contrasts between the 'soil rent theory' and the 'forest rent theory' were examined. The first theory was held preferable.The calculations demonstrated 50 years as best for the financial rotation with an interest rate of 3 %, after which also the influences of the fallow period, the cutting period, the ringing period and preceding culture on the financial calculations were studied. The income from teak forestry was compared with those of other tropical cultures. Through these and other considerations Beekman arrived at conclusions on the justification for teak forestry on certain soils.
