This chapter explores how precision farming techniques and technologies are used to manage water resources and tackle the challenges brought by climate change in agriculture. Precision farming relies on automation, sensors, drones, and/or telemetry systems to monitor soil conditions, water availability, and weather patterns. By doing so, farmers can optimize productivity, use resources efficiently, and reduce greenhouse gas emissions. Precision water management helps farmers make learned decisions about irrigation, saving water, and making crops more resilient to extreme weather. Additionally, climate-resilient crops, sensing techniques, and agrivoltaics help manage water efficiently and reduce climate risks in farming. Technologies like remote sensing, wireless sensors, and agrivoltaics provide promising solutions for water resource management, ensuring sustainable farming practices despite water scarcity. These approaches improve water efficiency, boost crop yields, and enhance resilience to climate change, building a sustainable future for agriculture.
