摘要

This paper deals with heavy pressures to save water in natural resource management due to increased waternscarcity. We take the example of a Chinese watershed and investigate the water use efficiency in Chinese irrigatednagriculture through a field study as dependent on investments in on-farm water saving technologies and canalnwater conveyance. The economic and environmental impacts of farmers adopting modern irrigation technologiesnand public sectors improving water transit systems are studied in particular. A spatial mathematical programmingnmodel is employed for optimization. The emphasis is on private and public investments in water saving. Waternsaving in a canal system enables an extension of the system and provides food and income for more farmers. Thenmodel results are of great value for policy makers and project managers, who want to optimize irrigation projects,nbecause scenarios (for instance water and product pricing) are provided. We also provide references for farmers innapplying suitable irrigation technologies.
