Abstract
Soils are non-renewable resources. World-wide in many regions a sustainable
use of soils is endangered through anthropogenic accelerated soil erosion. From
the economic point of view erosion protection is the transfer soil use potential
into the future. However, in developing countries such as Indonesia usually only
short term profit counts and consequently soil resources suffer from accelerated
exploitation. Advising farmers that soil erosion protection measures not only
ensure a prolonged agricultural potential for the future, but can also include
economic benefits is a promising attempt to promote the use of soil erosion
protection measures. The prerequisite for the decision process on a farm level is
the possibility to estimate the costs of soil erosion. In Indonesia mostly reliable
data are missing, and also no expensive surveys can be accomplished. Therefore,
less data intensive methods such as the \“replacement cost” or the \“productivity
change” method were used to estimate the \“on-farm-costs” of soil erosion in
Sleman on Java. The \“replacement cost” method resulted in clearly higher costs
compared to the \“productivity change” method. This is due to an over-estimation
of the costs by the \“replacement cost” method. The use of both methods
comparing costs and benefits of soil protection measures indicate similar
decision guidelines. However, more information is necessary on the additional
effects of soil conservation and political constraints to be a base for sound
decision-making on a farm level, but making information available on the
benefits of conservation measures helps farmers in their decision process to
invest in soil conservation. Beyond this, soil erosion is also a societal problem,
including external costs making up a large portion of the economic effects of soil
erosion.
Keywords: soil erosion, on-farm costs, replacement cost method, productivity
change.
