Technological Advancement and the Economic Benefit of Indonesian Rain-Fed Farming Development

摘要

The contribution of rain-fed farming to national food production in Indonesia has yet to be optimal. The major constraint has been limited water supply, where it relies exclusively on the rainfall, and hence its planting index (PI) is still low, on average only 1.05. The establishment of water management system to support rain-fed fields with the introduction of suitable cultivation techniques (gogo rancah, walik jerami, super jarwo, and ratoon paddy) is known to be effective in rain-fed farming. Further, the use of drought-tolerant paddy variety and changing cropping pattern to focus on paddy, maize, and soybean would potentially improve the food production capacity in Indonesia. This study has shown these interventions, when applied to the existing 4 million ha rain-fed fields, are estimated to increase annual rice production by 16.7 million tons. The production of maize and soybean is also expected to increase by 3.7 million tons and 0.98 million tons per year, respectively. It is beyond the scope of this study, however, to consider the actual benefit felt by rain-fed smallholder farmers. Future research with farmers as its focus and the capacity of Indonesian institutions toward rain-fed farming thus will contribute further to the rain-fed farming development in Indonesia. This article shares a strategy in maximising the contribution of the currently available 4 million hectares of rain-fed land to the national food production, and hence sustainable food self-sufficiency in Indonesia.
