Abstract

The need for irrigation water would be influenced by the fluctuating meteorological effects under the circumstances of climate change, and irrigation water will always represent the majority of water use in Gobu Seyo district. The purpose of the study was to look into how climate change would affect the amount of water needed to irrigate pepper and potatoes. The entire crop water consumption as well as the irrigation needs for the current and upcoming decades were modelled using the CROPWAT 8.0 software. In addition to the base period (1990-2019), forecasts for the future scenarios (2023-2052) and (2053-2082) were made using a MarkSim-GCM and the output ensemble of 17 GCMs for the medium (RCP4.5) and high (RCP8.5) emission scenarios. The analysis shows that in both scenarios (RCP8.5 and RCP4.5) and time periods (2023-2052 and 2053-2082), the agricultural water needs of both crops increased from 4.18% to 7.49%. The change in crop water requirements was highest for the mid-term period under the high emission scenario (RCP8.5), and the lowest for the near-term period under the medium emission scenario (RCP4.5). The range of the crops chosen for the research area's irrigation water requirements was 0.29% to 6.12%. While RCP4.5 with near-term time recorded the least change, RCP8.5 with mid-term period showed the most increasing change. The results strongly imply that the research area's chosen crops' water and irrigation needs will be significantly impacted by future climatic changes. In order to enhance the low level of water usage efficiency now in place, it is advised that farmers, water managers, water user associations, and decision-makers collaborate in the future to increase water storage, distribution, and crop output.
