Rainwater Management Model Development for Agriculture in the Savu Island Semi-Arid Region
Abstract: Savu Island is a
semiarid region with few rainfalls. The meager annual rainfall of about
1,000-1,500 mm that lasts for three to five months tends to cause draught. To
cope with this situation, the Author tries to develop a rainwater management
model located in Daieko village. This model constitutes an infrastructure that
consists of check dam series which are constructed by simulating a computerized
model of decision supporting system called “Rainwater Management for
Agriculture Decision Support System (RMA-DSS) model” in the research location
of Daieko village. Employing a simulated RMA-DSS model; the locations for
check-dam series, and dug-wells can be determined, the size of potential
irrigable lands can be determined based on water balance analysis of water
samples taken from simulated check dams and inundated lands. Through this model
the sufficiency of water supply for agricultural purposes and the land size for
cultivation area can be predicted with a high degree of certainty.
