Yellow River Basin, Water Resource Demand-Supply Balancing and Piecing Policy

Kameyama首先通过GTAP、CGE（可计算一般均衡）模型研究了“气候变化对农业部门的影响”。最近，随着中国经济的快速增长，食品进口量呈上升趋势，因此，中国的粮食进口量也呈上升趋势。投入资源已从农业部门转移到非农业部门。为了研究CO2对作物生产力的影响，以下问题变得越来越重要：（i）水资源潜在可利用性的变化，（ii）CO2对作物生长的直接影响。第二，龟山要求中国农业科学院农业政策研究所的胡教授进行实地调查，以检查 ...更多信息 水用户协会的成立，农业生产的Kameyama参与了调查问卷和分析的制定过程。过去由于灌溉制度的自上而下方案，种植模式的自由度较低，最近通过建立用水者协会，使用水者可以根据自己的管理需要向用水者协会申请灌溉要求。WATANABE首先通过翻译中国农业科学院水利部田间灌溉研究所最近发表的《灌溉与排水》系列论文中的两篇论文，总结了中国北方农业在节水技术和可持续用水方面的进展。其次，参观了该研究所后，渡边进行了生态农业研究，通过节水技术和水资源管理来减少土壤盐渍化的危害。

KAMEYAMA examined, firstly, "the impact of Climate Change for Agricultural Sector'' by, GTAP, CGE(computable general equilibrium) model Recently as China achieved rapid economic growth country the increasing trend of food import has been observed and accordingly several. inputs resources have been transferred from agricultural sector to non-agricultural sector. Tb investigate the impact for crop productivity, the following issues are increasingly important, i) the change of potential availability in water resource, ii) the direct effects of C02 to crop growth Although the conversion of the water sector model developed by World Bank by Positive Mathematical Programming procedure has attempted as in the proposal, still continuing efforts is needed in order to corporate the current land use change in agricultureSecondly, KAMEYAMA requested the field survey to Professor Hu in the Research Institute of Agricultural Policy in Chinese Academy of Agricultural Sciences, to examine the effect of … More establishment of Water Users Association to agricultural production KAMEYAMA was involved in the developing process of survey questionnaire and analysis. The degree of freedom of cropping pattern used to be low due to the top down scheme of the irrigation schedule, recently by establishing WUA made possible for the water users to apply to request of irrigation to WUA based on their own management need. The institutional framework has been somehow flexible and promoted the efficient water resource useWATANABE, firstly, summarized the augment regarding the water saving technology and the sustainable water use in north China agriculture, by translating two research papers in recent series of "Irrigation and Drainage" published by Research Institute of Field Irrigation in Ministry of Water Resources, Chinese Academy of Agricultural Sciences. Secondly, having visited this institute, WATANABE engaged in ecological agricultural research to reduce the soil salinity damage by water saving technology and water management Less
