Abstract

Economic valuation of rice irrigated area as the flood mitigation was carried out in Sidoarjo Regency, EastJava Province of Indonesia. Rice irrigated area which was still valuated as the food producer or plantation media during the time, in reality it could be functioned as small dams for storing rainfall for certain time. The function of irrigated rice area as the small dams was ad water support power which was able to hold, absorb, and store rainfall. Irrigated rice area as the flood mitigation was as non marketable goods. which was then in this study there would be carried out economic valuation. This study intended to investigate how much economic valuation of irrigated rice area as the flood mitigation that was as non marketable goods. The methodology consisted of Replacement Cost Method (RCM) for evaluating on environmental service of irrigated rice area. Results showed that there was very high function of rice irrigated area for storing rainfall while before flowing to downstream. Therefore, if there was happened the conversion of irrigated to non irrigated rice area would cause the lossing on flood mitigation of rice irrigated area that was proportional with 1,017 m3water per-hectar. The economic valuation of rice irrigated area on storing rainfall as the flood mitigation in location of studmillyards per-year was as Rp. 45,560,583.00 or Rp. 4,179,870.00 millions/ha. Based on the concersion of rice irrigated area in location of study during the last 10 years such as 300 hectars/year, the lossing valuation of rice irrigated area as the flood mitigation was Rp. 1.25 millyards/year. Extremely, if the whole irrigated rice area were functioned change into non irrigated one, the economical loss was as Rp. 92.87 millyardsKeywords: valuation, economy, irrigated rice area, floods
