| Research Abstract |
Project of land improvement usually produces not only the direct effects which are the increasing agricultural production and the decreasing input labour-force, etc, but also the indirect effects which are the stabilization of food supply, cost down, and further the development of regional economy,etc. It is the subject in this study that we explore a method to evaluate synthetically the direct effects and the indirect effects.
Those effects are produced under the interaction of various factors which are made up of the agricultural structure and the regional economy. Therefore I understand those multi-interasctions as an complex system, and according to the System Dynamics Modeling, I modeled the complex system on the real system by simulation.
Before this study, I had constructed the basic model for the Toyokawa irrigation project and the readjustment of farmland in the Tahara district. So I had new investigation for the readjustment of farmland in the Anjyo-chyubu district and Mikumo-Nanbu district,and the construction project farmland in Tsumagoi-Seibu district. Then I added to modify the basic model by these new investigation, and was able to construct the SD model with high application.
I measured the effects in the six sectors, that is,agricultural production, regional industry, population, working population, resource use, and local goverment finance.
according to the above effect analysis, if we will make use of the SD model which I had improved, we will be able to measure and evaluate the various effects on many kinds of project of land improvement.
