GIS based graphical user interface for irrigation management Saroj Acharya, Ashish Pandey, S. K. Mishra and U. C. Chaube ABSTRACT A geographic information system (GIS) based graphical user interface for irrigation management within an ArcGIS customization has been developed using Visual Basic for Applications for estimation of spatially distributed irrigation water requirements. It is capable of providing an appropriate framework for manipulating, visualizing and analyzing spatial data to support decision making in irrigation management. Its application is demonstrated through a case study for use in the eld. Saroj Acharya Ashish Pandey (corresponding author) S. K. Mishra U. C.

According to the Food and Agricul- ture Organization (FAO), one of the biggest challenges for agriculture in the coming decades will be to ensure food security for the worlds steadily growing population (Bergez et al. ). Proper management of an irrigation system reduces water demand, which leads to water saving for other uses, improves agricultural productivity, and further helps in reduction of the environmental impact of irrigation (Hargreaves et al. ; Suryavanshi & Reddy ; Bastiaanssen et al. ). Irrigation management is therefore of paramount importance to irrigation professionals/planners/managers, for it involves multi- tasks and multi-stakeholders with varying goals. It is of common experience that spatial and temporal variabilities create problems for traditional irrigation management sup- port systems (Lin et al. ). Customization of geographic information systems (GIS) with Visual Basic for Applications (VBA) can be a solution for irrigation management. Most of the data related to irriga- tion management is complex as it is both temporally and spatially distributed in nature (Pervez & Hoque ; Naidu & Giridhar ). Its integration has led to the intro- duction of GIS and other technologies (Martin ; Bastiaanssen & Bos ; Bioggio & Ding ; Kjelds & Storm ; Nixon et al. ; Su & Wen ; Ray et al. ; Liang & Wu ) in irrigation management. GIS play an important role in transferring information in easily communicable form, such as maps, to farmers, planners and experts for irrigation planning and management (Maguire et al. ; Goodchild ; Ray et al. ; Muthanna & Amin ; Todorovic & Steduto ; Suresh Babu et al. ). GIS have been widely applied in all scientic elds and practical activities. With environmental management, their use covers a broad spectrum, including a simple formula, and visualization of natural data as maps, visualization of pollutant concentrations in the environment and their spatial distribution (Gajos & Sierka ). Sheate et al. () developed a methodology for mapping ecosystem ser- vices using GIS and readily available, existing land use/land cover datasets. Karteris et al. () used GIS extensively to extrapolate the results from the building to the city scale and 1536 © IWA Publishing 2016 Water Science & Technology: Water Supply | 16.6 | 2016 doi: 10.2166/ws.2016.081 Downloaded from https://iwaponline.com/ws/article-pdf/16/6/1536/411093/ws016061536.pdf by guest on 16 June 2020
