Assessing the financial performance of water user associations: a case study at Great Menderes basin,Turkey

Management, operation and maintenance services of about 1.7 million ha irrigation areas, constructed the scheme by State Hydraulic Works (DSI) were turned over to Water User Association (WUA) in Turkey. The number of the WUAs is 330 in Turkey for 2005. There is therefore an urgent need to study methods of measurement and evaluation of financial performance of WUA in order to improve the financial performance and raise the management level of WUA. This paper proposes 12 financial indicators in order to measure and evaluate the financial performance of WUAs. Based on the results in four irrigation schemes and WUAs in Great Menderes basin, Turkey, the methods of measurement and calculation of financial performance indicators selected, and difference factor value related to each indicator are presented. Several financial performance indicators and difference factor values varied widely 1999 to 2004. Therefore, these financial performance indicators should be carefully evaluated and monitored for financial sustainability of WUAs.     

The impact of the New Rural Cooperative Medical Scheme on the “health poverty alleviation” of rural households in China

This study investigates the impact of the New Rural Cooperative Medical Scheme(NRCMS) on rural households to escape poverty. We employ the instrumental variable method, the IVProbit model, to analyze the national data from the rural-resident field survey by the China Family Panel Studies(CFPS) in 2016. Based on the large-scale data, we found that, first, the hospitalization of family members is the key factor in increasing the risk of the family falling into poverty. The NRCMS has significantly reduced the likely risk of falling into poverty. Second, the impact of the NRCMS on poverty alleviation varies among groups with different levels of income. There is no impact on the upper-middle and high-income groups; in contrast, the NRCMS has substantially improved the capacity of low-income rural families to prevent poverty due to illness, especially for the lower-middle-income group. Third, there exist significant regional differences in the impact of NRCMS on the health poverty alleviation of rural households in China. The NRCMS has successfully reduced the risk of rural households in the western region falling into poverty, simultaneously, no significant impact on those in the eastern and central regions. In order to diminish and eliminate poverty eventually and boost rural residents' capacity for income acquisition, we propose the following: raise the actual compensation ratio of the NRCMS, control the rising expense of NRCMS by promoting the payment method reform, construct the comprehensive healthcare system in the western region, strengthen the medical security for the poor in remote area, and enhance the living environment for rural residents.

日光温室节水灌溉模式评价研究

建立了温室灌溉模式的评价指标体系,提出了基于多目标决策灰色关联投影法的温室灌溉模式的综合评价方法,介绍了该方法的原理。以哈尔滨香坊农场为例进行了实证评价分析,并将投影寻踪法、模糊物元法的分析结果与灰色关联投影法的分析结果进行对比,发现这3种方法所得灌溉方案的优劣排序基本一致且与实际情况相符。     

基于AHP的水利水电工程项目设计方案优选应用

为了更好地评价水利水电工程设计过程中比选方案的优劣,采用层次分析法(AHP)建立水利水电工程项目设计方案比选指标体系及结构模型,从多因素综合定量评价各比选方案.结合工程实例,综合考虑地质地形,水文水能、枢纽布置、工程施工、运行条件、工程淹没、环境条件、经济指标等设计中的主要因素,并对设计方案的各项指标进行量化,最终确定最优设计方案.结果证明,AHP法能为水利水电工程项目设计者进行方案优选决策提供定量依据.
