Abstract
Chronic water shortage is one of the most pressing problems in the arid areas of
China and as a compensation measure, the introduction of water-saving irrigation
facilities has been proposed for water use in agriculture. However, in the Ugen
River Basin, these water-saving irrigation facilities have produced varying
results ranging from success to failure. Therefore, this study examines such cases
and considers the factors responsible for the effective introduction of watersaving
irrigation facilities in these regions. In general, capitalist farmers are
individually responsible for the introduction, maintenance and management of
the water-saving facilities, whereas general farmers collectively manage and
maintain the facilities built with government subsidies. In addition, this study
reports two cases in which collective management either required initial
investments or covered all of the initial investment costs through government
subsidies. However, these facilities were not necessarily well managed because
of the differences in the management group, thus affecting their outcomes as an
effective water-saving irrigation facility. By using game theory to obtain an
optimal solution, the results of this paper indicate that the cost of work and
maintenance accrued by the introduction of the water-saving facilities was less
compared to both the incentives received in water-fee reductions as well as the
increased yield of water-saving irrigation. Finally, we suggest that either the
current yield needs to be increased twofold or the water fee needs to be increased
for effective management of water-saving irrigation facilities, particularly in
regard to collective management.
