Irrigation is essential for efficient and sustainable agricultural production, particularly in arid and semi-arid areas. According to the Food and Agriculture Organization (FAO), one of the major challenges for agriculture in the coming decades will be to ensure food security for the constantly growing world 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 improve agricultural productivity. Irrigation management is one of the biggest challenges for irrigation professionals and managers because it involves multiple activities, multiple stakeholders with different objectives. Efficient water management allows the optimization of available water, effective control over the quality of agricultural products further helps reduce the environmental impact of irrigation. Most irrigation management data 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; Kjelds and Storm, 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 for irrigation planning, management and research providing information more effectively and accurately. ArcGIS is the most commonly used GIS application in irrigation and water resources management projects. ArcGIS not only allows the user in a... middle of paper......irrigation management. Chapter 3 (Theoretical Framework) covers the theoretical background on the Geographic Information System, ArcGIS and its customization and Visual Basic for application development environment. This chapter also describes the water requirement for irrigation with reference evapotranspiration and crop evapotranspiration. Chapter 4 (Materials and methodology) describes the data with its source and the software used during the study. This chapter also provides description of the methodology used to develop the tool and its application for output maps. Chapter 5 (Software description and results) provides the general description and characteristics of the developed software. This chapter also provides the output maps produced by the developed tool. Chapter 6 (Conclusion) presents the conclusion of the study along with limitations and further development of the system.
