N2 - Climate change significantly impacted climate conditions and crop water requirements in the Majalengka Regency, a super-priority location related to climate resilience in the agricultural sector. In dealing with the impacts of climate change, the relationship between crop water requirements to climate change could be projected using the General Circulations Model with scenarios of RCP 4.5 (medium-light change) combined with the CROPWAT 8.0 model. This study aimed to determine the effect of climate change and the crop water requirements for rice plants in the three districts with the broadest rice fields in the Majalengka Regency from 2021-2025. This research found that climatic conditions in Majalengka Regency between the year 2021-2025 experienced changes in the average temperature, where the average temperature decreased in 2022 but continued to increase in 2023-2025 with an increase of 0.1°C- 0.24°C. Then from 2023-2025, the average maximum temperature increases by 0.39°C-0.47°C. On the contrary, the total rainfall each year decreased compared to 2021. Based on the calculations, the crop water requirement was always higher than adequate rainfall, so irrigation water was needed. The highest irrigation water requirement had a discharge value of 10.45 l/sec/ha.
