Valuation of landmass degradation using fuzzy hedonic method: A case studyof National Capital Region

A Hedonic model to determine the revealed willingness to pay for landmass o f different suitability classes, based on landmass functional characteristi cs obtained through subjective assessments, is developed for the National C apital Region in India. The inherent non-specificity involved in subjective evaluation is minimized using fuzzy logic based regression technique. The proposed fuzzy regression involves regression using central values of trian gular fuzzy number and minimization of non-specificity using linear program ming. The revealed willingness-to-pay for landmass of different suitability classes is used for valuation of disbenefits due to urban expansion on lan dmass of different agricultural suitability classes in National Capital Ter ritory of Delhi. Appropriate pricing policies to prevent the future inappro priate landuse practices are developed using the landmass valuation.
