Variations in rainfall and temperature due to climate change, combined with unsustainable water consumption patterns, are affecting water availability. According to the Global Environmental Outlook 2000 of the United Nations Environment Programme (UNEP), water scarcity can be considered as one of the most critical environmental issues of the 21st century and will negatively impact all sectors. Water scarcity and increasing competition for water resources pose critical challenges to agriculture, particularly for water-intensive crops such as rice. In this context, assessing irrigation requirements is essential for the development of effective water-related policies and for optimizing irrigation management, ensuring sustainable water use and preserving agricultural productivity.
