This article examines how climate change affects the water needed for irrigation in urban areas. The researchers looked at various factors like temperature, humidity, and wind to understand how they impact the amount of water crops need. They also considered how changing agricultural land and irrigation efficiency affect water requirements. By analyzing climate trends and land use changes, the study found that as urban areas grow, there might be less land for agriculture, leading to reduced water needs for irrigation. This research aims to help develop ways to calculate the right amount of water for irrigation under changing conditions.
