Abstract

Climate change is the most serious challenge facing the world nowadays. This scenario is caused by the rising of carbon dioxide (CO2) in the atmosphere. The agricultural sector is the most affected by climate change. In Malaysia, rice is main food consumed, thus paddy is considered as the most important crop in Malaysia. Therefore, it is important to plan irrigation in order to improve water use efficiency for rice production and therefore to sustain the productivity of rice. The Land and Water Division of the Food and Agriculture Organization of the United Nations (FAO) has established the AquaCrop model to solve this problem. This model can simulate the relation between soil, water and plant. The main purpose of this model was to predict or to simulate yield for the future in a particular area. Therefore, farmers can follow the recommendation from the AquaCrop model to maximize productivity while minimizing the risk of uncertainties. This study used two types of Representative Concentration Pathway (RCP) scenarios which are RCP4.5 and RCP8.5. Under these RCP scenarios, there are different levels of sink strength that have been applied (0%,10%,20%). The result showed that water productivity under RCP8.5 was higher when compared to RCP4.5. Similarly, the simulated yield showed the same result as water productivity.
