The role of water in agriculture is essential and plays an important role in food security. We need to better understand how to optimise water use in agriculture to meet both global food security and water management efficiency goals. Earth observation with satellite offers the opportunity to map, monitor and better understand the dynamics of agricultural water. However, the applicability and accuracy of these observations need to be better understood. This dissertation aims to better understand the suitability of large remote sensing-based datasets for the monitoring of crop water productivity (CWP). CWP being an indicator of agricultural water efficiency.
