Development of Spatial-System Dynamics Model for Food Security Policy in Indonesia: A Generic Sub-Model Simulation
Abstract: The Indonesia has
the immense geographic condition and heterogeneous condition, therefore food
security issues could not be aggregated nationally, instead, they have to be
described per region. In this paper, the region is defined as a province. Food
security issues in every region are dynamic, and generated with complex system
structure, will be described in the paper as follows. First, in order to have
the comprehensive description of food security, we develop a new spatial system
dynamics model that combines the concept of space and time. Previous spatial
system dynamics methods could only describe the dynamics of the
natural/physical system. The new spatial system dynamics proposed in this paper
is designed to accommodate human decision for policy intervention. Then, we
develop a decision support system, as follow. (1) After comparing
characteristics of each province, we can identify the similarity of all
province. We call the similarity as the generic model. (2). We propose a new
method of spatial system dynamics that can accommodate the immense geographic
condition and the heterogeneity. (3) By combining the generic model and the new
method we propose a comprehensive model for decision support system in food
security policy. Finally, from the experiments with a simulation of the
comprehensive model, we could understand that a policy intervention of food
security could give impact differently toward each region.
