چکیده مقاله :

    تالاب­ها برای ارایه خدمات اکوسیستم با ارزش ضروری هستند. برنامه­های احیا و حفظ تالاب­ها، عرضه خدمات اکوسیستمی را افزایش خواهد داد. هدف از این مقاله، برآورد ارزش کل اقتصادی برنامه­های احیا و حفظ تالاب جازموریان در استان کرمان است. داده­های مورد نیاز برای تحلیل از راه مصاحبه از 312 خانوار مناطق اطراف تالاب جازموریان در سال 1396 گرفته شد. در ابتدا، روش کوپر بمنظور طراحی بهینه برای روش ارزش‌گذاری مشروط انتخاب دوگانه مورد استفاده قرار گرفته و مقادیر پیشنهادی و اندازه نمونه متناظر با هر پیشنهاد محاسبه شد. سپس، مدل­های لاجیت و کم‌ترین مربعات معمولی به منظور محاسبه کل ارزش اقتصادی برنامه­های احیا و حفظ تالاب تخمین زده شد. نتایج نشان دادند که بر مبنای جمعیت مناطق اطراف تالاب جازموریان، ارزش کل اقتصادی برنامه­های احیا و حفظ تالاب در محدوده­ی 412/34 تا 566/63 میلیارد ریال در سال است. این تخمین­ها می­تواند جهت توجیه سطح مخارج برنامه­های احیا و حفظ تالاب جازموریان استفاده شود.   طبقه­بندی JEL: Q₂، Q₅، Q₂₄، Q₅₁، Q₅₇، Q₂₅₀.

چکیده انگلیسی:

    Wetlands are vital to the supply of valued ecosystem services. The restoration and preservation programs of wetlands would increase the supply of ecosystem services. This paper aims to estimate the total economic value of the restoration and preservation programs of Jazmourian wetland in Kerman. Data required for the analysis was taken from 312 households interviews in the regions of Jazmourian wetland in 1917. In the first, this paper employs Cooper's method for optimal survey design for the dichotomous choice contingent valuation method. This method finds the bid amounts as well as the sample size corresponding to each bid. Then, Logit and ordinary least square models were estimated for the total economic value of the wetland restoration and preservation programs. The result shows that, based on the population of Jazmourian wetland around regions, the estimated total economic value of the wetland restoration and preservation programs ranges from 34.412 to 63.566 billion Rials per year. These estimates may be used to justify the level of expenditure on the restoration and preservation programs of Jazmourian wetland.                                  JELClassification: Q₂، Q₅
