Protocols for estimating magnitudes and values of paddy rice multiple functions uri icon

abstract

  • This paper presents protocols for estimating the magnitudes and monetary values of two non-market outputs from paddy rice production. The protocols were developed during a workshop held in Taiwan in 2004 to set guidelines or protocols for measuring the multi-functional attributes of positive and negative externalities of paddy rice. The externalities attributed to paddy rice include groundwater recharge, subsidence reduction, flood damage amelioration, change in water quality, change in air quality, and preservation of scenic value. Methodologies were set forth for measuring and valuing each of these externalities. Two that reflect differences in complexity - groundwater recharge and change in air quality - are discussed here. The protocols consider regional variation, the need for evaluation of net effects, and the avoidance of double counting. The conclusions presented are those from the workshop as a whole.
