Suggestions for future developments
1. Further rationalization of decision determinants with appropriate nesting of causal factors
of these determinants. Other participatory appraisal tools may be explored or developed
if required.
2. Explore ways to combine group and individual survey approaches to acquire necessary
information for modelling farmers’ decision making process.
3. Expand the decision options to include other land use forms, e.g. conversion to oil palm,
choice between clonal rubber plantation or seedling plantation.
4. Calibration of the networks in different village scenarios. Running these models in front
of the farmers will attract comments and suggestions that can improve these models
significantly.
5. Explore and incorporate following variables where appropriate:
ƒ alternative labour sources and sinks in the decision models (share tapping, hired labour,
gotong royong);
ƒ rubber price variability;
ƒ availability of external support for land conversion;
ƒ farmer categorization and its implications on their decision behaviour (e.g. the
transmigrant Javanese and the local population have different perceptions and attitudes).
6. Consultation with experts in behavioral modelling domain to explore more efficient ways
to gathering information and translating these into models.
