The changes in climate behavior will probably bring changes to the hydrological cycle. As a result, these variations will probably affect crop development, crop production, and water consumption.
Therefore, the project’s proposal is to determine the water requirement for irrigation in the current weather and in different future climate scenarios for the cropping of pineapple and coconut in the North, and orange, in the Northwest of the state of Rio de Janeiro, Brazil, since those are the crops of greatest expression in these two regions.
