Irrigation is essential for efficient and sustainable agricultural production, especially in arid and semi-arid areas. According to the Food and Agriculture Organization of the United Nations (FAO), one of the biggest challenges for agriculture in the coming decades will be ensuring food security for an ever-increasing global population. . Irrigation is one of the most important inputs for efficient and sustainable agricultural production (Gundogdu et al., 2002). Irrigation system management reduces water demand, saving water for other uses and further helps in improving agricultural productivity. Irrigation management is one of the major challenges for irrigation professionals and managers as it involves multiple tasks, multiple stakeholders with varied objectives. Efficient water management makes it possible to optimize available water, effective control of the quality of agricultural products also helps to reduce the environmental impact of irrigation. Most data related to irrigation management are complex, spatially distributed and temporal in nature. The integration of irrigation data and its use in irrigation planning and management has led to the introduction of geographic information systems (GIS) and other technologies (Su and Wen, 2001; Bioggio and Ding, 2001; GIS is a very effective tool for providing information to farmers and irrigation professionals in the form of maps using interpolation. These maps can be easily understood by farmers, planners and specialists in irrigation planning, management and research, providing information in the most efficient and accurate way. ArcGIS is the most commonly used GIS application in irrigation and water resource management projects. ArcGIS not only allows the user to...... middle of paper ...... irrigation management. Chapter 3 (Theoretical Framework) covers the theoretical background of Geographic Information System, ArcGIS and its customization, and Visual Basic for Application. development environment. This chapter also describes irrigation water requirements with reference evapotranspiration and crop evapotranspiration.
