Abstract

Development has ended isolation in many parts of Kalimantan, Indonesia, and provides previously isolated communities with the opportunity for greater involvement in a market economy. This paper describes the use of a simulation model to study the possible impacts of greater involvement in cash cropping in swidden agricultural systems. The model uses both individual-based and rule-based modelling approaches. The model formulation is based on a previous report of the social structure, culture and agricultural production system of the Kantu' in West Kalimantan {[}Dove, MR., 1985. Swidden Agriculture in Indonesia: The Subsistence Strategies of the Kalimantan Kautu'. Mouton Publishers, Berlin]. The model simulates: (1) births, deaths, marriage, household formation and dissolution; (2) land use decisions on the type, number and location of swidden cultivation; and (3) tracks the consequences of those decisions at a landscape level as well as the economic welfare of the households. The model deals with swidden cultivation of rice and the planting and tapping of rubber. The paper presents a simulation `experiment' that compares different land use strategies under a scenario of fluctuating rubber price. An important finding is that maintainings widden cultivation as `an option' in the farming system, rather than permanently replacing swidden cultivation with cash cropping, appears to be a safer strategy to moderate the impact of commodity price fluctuations.
