Title: AQUA : an integrated water model for tropical cropping : mechanics, validation, and applications to Costa Rica
Abstract: This paper reports the work carried out in Costa Rica between July 1985 and August 1986. The work's main objective was aimed at contributing to the increase in productivity and stability of tropical rainfed cropping systems, by designing cropping schemes that may prove to be more efficient in relation to water, which is by far the envionmental variable that regulates tropical agriculture. Increases in productivity were considered as increases in yield per crop, and in number of crops grown per year. The methodology devised to characterize and evaluate the effects of both water deficits and excesses on crop yields, was developed as the computerized model AQUA, which is based on daily water balance calculations and on rainfall expectancy and prediction considerations. AQUA was subsequently used to design more water efficient rainfed cropping schemes.
