Quantification and Evaluation of Water Requirements of Oil Palm Cultivation for Different Climate Change Scenarios in the Central Pacific of Costa Rica Using APSIM

Climate change is a variation in the normal behavior of climate. These variations and their effects will be seen coming years, most imminent being anomalous fluctuations atmospheric temperature precipitation. This scenario counterproductive for agricultural production. study evaluated effect climate on oil palm production conditions Central Pacific Costa Rica, three simulation scenarios: baseline between years 2000 2019, first from 2040 to 2059 (CCS1), second one 2080 2099 (CCS2), using modeling framework APSIM, necessary water requirements were established as an adaptive measure crop with irrigation module. A decrease annual precipitation 5.55% 7.86% increase average 1.73 °C 3.31 identified, generating yields 37.86%, concerning Baseline, CCS1 CCS2, respectively. Irrigation made it possible adapt available soil maintain proposed scenarios.
