River Yamuna

River Yamuna is an important river in India that flows through the national capital—New Delhi. The river water offers a variety of functional uses in its basin area. A progressive deterioration of river water quality had rendered it to become almost a channel of wastewater. However, there is a willingness-to-pay (WTP) for the conservation of river water quality among the citizens of the basin. This paper reports on an application of Contingent Valuation Method (CVM) for estimating the economic value of river water conservation (both for current water quality maintenance and for the restoration of river water quality). The results show that there exists a WTP for the conservation of river water quality, which is about 14.93% higher for water quality restoration than that for maintenance of current water quality. Some of the issues in undertaking the CVM studies in developing countries are also discussed in the paper.

The purpose of this study is to estimate the economic value of Geomun Oreum (GO), a parasitic volcanic sieve, for sustainable management by using the dichotomous choice contingent valuation method. To address the exaggeration tendency of willingness to pay (WTP), the contingent valuation method’s (CVM’s) traditional threshold, respondents’ WTP answers were reconfirmed to screen only true responses for our analysis. In addition to estimating the economic value, the causal relationship between the tour guide’s quality of explanation and the respondents’ payment intention is examined in the study. The results reveal that the estimated preservation value of GO is 35,881 KRW (33.28 USD), and the quality of the tour guide’s narrative is statistically related to the respondents’ payment intention.

This paper applied Contingent Valuation Method (CVM) to estimate the recreational value of Urban Park— “219 park”. The economic value analysis of recreational activities will technically enrich the connotation of part management, which can benefit the transition of recreational activities and resource management from extensive to intensive; by compared the two results, it will also provide a important references on rules and measures for government and relevant authorities.

Aim of study: To estimate grazing fee and the economic value of the communal rangelands of two groups of ranchers. Area of study: Ejido Tanque de Arenas (ETA) and ejido Tanque de Dolores (ETD) in Catorce, San Luis Potosí, Mexico Material and methods: The contingent valuation method with referendum format was used to propose a grazing fee that would allow conservation and continuity in the use of the common resource. The field information was collected by interviews and was processed in the PASW Statistics 22 software NLOGIT Version 5.0. Main results: Perception of rangeland deterioration, age, size of the herd, and level of income are characteristics of ranchers that influence the willingness to pay. From the coefficient of rangeland of the region (24.2 ha/AU) a monthly grazing fee of USD 7.18 per animal was calculated. Research highlights: Estimation and payment of grazing fees are an alternative to avoid the deterioration of communal rangelands, without incurring land parcelization.

Background: Although the Kruger National Park (KNP) is a protected area, it is not exempted from anthropogenically induced impacts, which often compromise river water flow and quality. Measures of river water quality in South Africa have conventionally been based on water chemistry as well as different ecological indicator groups such as fish and macroinvertebrates. Diatoms have been shown to be useful indicators of changes in water quality resulting from pollution and land-use impacts.Objectives: To determine the applicability of diatoms for hind-casting water quality in the KNP and to compare recent diatom community composition with those from the 1980s.Methods: In this study, pH and electrical conductivity (EC) were used to evaluate temporal changes in water quality of three rivers within the KNP. Additionally, we made use of historic diatom samples from three of the five perennial rivers to evaluate if diatom communities reflected changes in water conditions between 1983 and 2015.Results: Diatom community structure was significantly different between 1983 and 2015. Diatom-based index scores (SPI) indicated an improvement in water quality for the Letaba and Olifants rivers.Conclusion: Diatoms were shown to be useful indicators of current water quality and are also useful for determining temporal changes.

Economic Value of Medicinal Plants in Danau Sentarum National Park, West KalimantanDanau Sentarum National Park (DSNP) is a conservation area which has an important role in people’s lives and society Kapuas Hulu in West Kalimantan. The objective of this study was to estimate the value of medicinal plants in the area TNDS. Contingent Valuation Method (CVM) with a single bounded was use to determine the willingness to pay for medicine plants. Data collected through direct interviews with 90 local households in DSNP using a questionnaire. Data analysis was done with MS. Excel® and SPSS® statistical software. The results show the variable value of the bid, income, age, education, and knowledge of medicinal plants significantly aect the value of WTP. The expected WTP is found between IDR50.354,22 to IDR72.312,44 per household per month.Keywords: Contingent Valuation Method; Single BoundWillingness to Pay; Danau Sentarum National Park (DSNP) AbstrakTaman Nasional Danau Sentarum (TNDS) adalah kawasan konservasi yang memiliki peran penting bagi kehidupan masyarakat di Kabupaten Kapuas Hulu dan masyarakat Provinsi Kalimantan Barat.
