Climate change affects irrigation water availability differently in various regions. In areas with increased precipitation, such as the northern latitudes, irrigation water availability may increase. However, in regions with decreased precipitation, such as the Mediterranean and parts of Africa, irrigation water scarcity will worsen. Additionally, changes in precipitation patterns, such as more frequent droughts and floods, can impact irrigation water availability in regions with variable climate conditions. Understanding regional climate projections is essential for developing effective adaptation strategies for irrigation water management.
