| Research Abstract |
Changes in circumstance surrounding irrigation projects requires a reconsideration of an evaluation method of projects. The changes attribute to not only a drastic change in agricultural production but also expansion of non-marketable and intangible effects stemmed from projects. This study was devoted to examine a current evaluation method and make a theoretical and practical proposal to improve it.
The conclusions are following.
1. The bigger irrigation projects, the greater deal of effects on industries and livelihoods. As a non-agricultural sector penetrates into a rural economy, irrigation projects inevitably cause external effects beyond an agricultural sector even if they are designed to construct agricultural facilities.
2. A tangible external economic effect of irrigation project stems from a water use for manufacturing and households. Although an evaluation of such an effect can be theoretically made without difficulty, we should take account of an institutional factor to practically accomplish a calculation of whole effects. A water transfer problem between an agricultural sector and an industrial sector is the most important issue to be considered.
3. Some non-marketable effects should be involved in benefit lists of irrigation projects. One of examples is a conservation of rural resources.
4. Some plans initially designed before starting projects are not necessarily appropriate to actual situations because of taking long time to complete projects. A revision of evaluation method is required in order to check feasibility of projects.
