The potential loss of rice production due to wetland conversion in East Java

East Java is one of the biggest rice producers in Indonesia. This statement is supported by the availability of wetland resources which are relatively larger than the area of wetland in other provinces. However, over the past few years, East Java is experiencing a significant decline in the wetland area, which can lead to a potential loss of rice production. This research aim to know the aggregate amount of potential loss of rice production that occurred in East Java due to the conversion of wetland. The data used are secondary data from Indonesian Central Bureau of Statistics from 2006 to 2015, including the data of wetland area, rice production and productivity in East Java as well as paddy and rice conversion factors from Food Security and Extension Agency. The method used is descriptive method. The potential loss of rice production can be calculated by multiplying the area of wetlands that are converted with rice productivity, and then the data is adjusted to the available conversion factors. The analysis shows that during the last 10 years there has been a conversion of wetland area of 23.585 hectares in East Java. The loss of wetland area caused the potential loss of rice production is 81.025 tons. The potential for lost production is equivalent to rice consumption for 94.148 people per year in East Java with an average amount of rice consumption of 86 kg per capita per year.
