A number of water development and conservation programmes are currently being undertaken in South Africa, one of the most notable being the Working for Water Programme. The economic rationale underlying the programme in selected mountain catchments in the Western Cape was presented by Van Wilgen et al. (South African Journal of Science, 93: 404–11, 1997) and Marais (Unpublished, PhD thesis, University of Stellenbosch, 1998). A cost–benefit analysis of the Working for Water Programme in the Mgeni catchment in KwaZulu‐Natal was conducted by Gillham & Haynes (Unpublished paper presented at Tenth South African National Hydrology Symposium, 2001). Cost–benefit analysis has also been conducted in the Eastern Cape by Hosking & Du Preez (South African Journal of Science, 95: 442–8, 1999). There are, however, aspects of these assessments which merit more attention than they have been given thus far. One of these aspects is the value of water benefits, and this article examines it from the perspectives of marginal cost and willingness to pay. It is shown that different approaches are appropriate for different project locations, and that significantly different results are being obtained using these approaches. It is concluded that great care is needed in relating the value of water benefits to the specifics of the various locations where the conservation project is being implemented. 相似文献

Eleven closely related experiments testing the free rider hypothesis under different conditions, and sampling various subpopulations, are reported. Results question the empirical validity and generality of a strong version of the hypothesis. Some reasons for its failure are discussed. 相似文献

Towards More Efficient Compensation Programmes for Tourists' Benefits From Agriculture in Europe 总被引:1,自引:0,他引:1
This paper covers nonmarket services provided by farmers for recreational purposes in several Central European regions. A regionally specified general equilibrium model is used to derive the efficiency conditions for a competitive equilibrium to guarantee a Pareto optimal outcome. Moreover, we present green agricultural compensation programmes in Europe and their assessment from an economic perspective. The empirical analysis focuses on tourists' willingness to pay (WTP) for the provision of agricultural landscape-enhancing services in Austria. A comparison of these measures with current voluntary compensation payments made to farmers for the preservation of an agricultural countryside in several Austrian tourism communities suggests that the hypothetical contingent valuation (CV) results represent a valid order of magnitude for the value of recreation-related agricultural services. As far as agricultural policy is concerned, environmental improvement, the stabilization of agricultural income levels, diminishing intrasectoral income differences, and the development of economically disadvantaged rural regions can be expected from directly subsidizing farmers for the provision of countryside amenities. 相似文献

German tourism research is an integral part of landuse and economic planning. This has led to the development and implementation of site attractivity and economic efficiency measures. Attractivity models incorporating a site's natural and artificial features are used to provide a comparative ranking of present and proposed tourist developments. Both cross-sectional and time studies indicate that the development of the tourist sector is not an efficient method whereby regional socio-economic disparties can be reduced. 相似文献
