Cost-Benefit Analysis of Land Improvement Project

-A Case Study of Kakogawa Western Area-

Abstract

In recent years, many land improvement projects are implemented in many areas in Japan. The main purpose of these projects is the improvement of agricultural productivity. But some economic problems are arising. The problems are low benefits to the public economy, heavy charges to the farm households economy, and so on. For this reason, it is needed to evaluate the projects economically.
In this paper, we try to show a method of cost-benefit analysis of aland improvement project, based on the case of Kakogawa Western Area, and try to evaluate the project economically. This paper consists of the following four main chapters.
(1) Basic concepts and some problems of cost-benefit analysis
(2) Calculation of costs
(3) Calculation of benefits
(4) Comparison of costs and benefits
And we evaluate this project from three standpoints. They are:
(1) national economy
(2) private economy of farm households
(3) charges to farm households economy.
