Economic Value Of Water

Water resources is one of the important drivers of socio-economic development, but the value of water resources in society is not clear. In order to accurately describe the impact of water resources on socio-economic value, a socio-economic value evaluation index system for water resources is established. This paper is based on the theory of utility value of water resources. Discussed how to use fuzzy mathematics and benefit sharing coefficient method to calculate the socio-economic value of water resources in different industries. Take the Golog Zang A.P in the source region of the Yellow River as an example. Calculated the socio-economic value of water resources for residential life, irrigation planting, industry, construction and tertiary industry. Finally, analysis results show that the value of comprehensive water resources in the study area is between 9.4-40CNY, tertiary industry highest, lowest value for domestic water. The calculation results provide a reference for the rational and efficient use of regional water resources and the scientific formulation of water resources policies.

Economic Value Of Water

This study aims to knowthe public perception of water usage and to determine the economic value of water from any use of and willingness to pay for forest and land rehabilitation.This research is held on March-Mei 2012 at Pesawaran Indah village, Padang Cermin, Pesawaran.To predicted the total economic value of water resources were used WTP method.The results of this study showed the total economic value of water is as much as Rp 1.705.844.764,-/year.These show that the public has higher willingness to pay of the total value, so it can be concluded that assess a community resource, Pesawaran Indah village has a perception of the water use is still low. One of factor is the exceeding availability of water resources, the community habit as free rider. It needs a policy of water management to maintain and conserve the water resources. Key words : economic values of hydrologic, WTP (willingness to pay)

Economic Value Of Water

Way Betung watershed is a source of raw water supply utilized by the Talang Mulya community for various purposes, such as for household needs, irrigation of paddy farming and micro hydro power plant. Water availability is closely related to the existing forest presence in the area, the forest land management should be in balance on be half of maintaing water availability. This study aimed to determine the perception of the community and to analyze the economic value of water for household needs, irrigation of paddy farming and micro hydro power plant. This research also calculated the Willingness to Pay of forest and land rehabilitation costs by community. Primary data collection were conducted by interviewing 106 respondents. The results showed that the community appraisal of water resources in Way Betung watershed were good since 88% of respondents are willing to pay for forest rehabilitation. The total economic value of water utilization in Talang Mulya Village was Rp.2.963.540.390/year and the value of willingness to pay for forest rehabilitation costs was Rp.5.833.608/year with average willingness to pay was Rp.22.948/year. Keywords: watershed , total economic value, the economic value of water, willingness to pay.

Value Of Water

Taking the source region of the Yellow River as an example, this paper first introduces the theory of energy value and its basic steps. Then combined with the Yellow River source area, the variation characteristics of precipitation and surface water resources from 1961 to 2011 in the Yellow River source area were analyzed, and both of them showed a trend of decreasing year by year. On this basis, using the theory of energy value, combined with relevant parameters, taking 2011 year as an example, further analyses the chemical energy and solar energy of water resources in the Yellow River source area, and gives the value of surface water resources. The value of water resources per unit is 1.59 yuan/m3. For the Yellow River source area, the overall value of water resources for the whole basin in 2011 is 33.55 billion yuan. It can provide a reference for the analysis of the value of surface water resources in the Yellow River Basin.
