Irrigation schemes in southwest India are heterogeneous in crops, area of irrigation units, soils and climate. The areas planned for irrigation each year under different crops and the scheduled duration of irrigation to each farmer are estimated, however, based on assumed uniform characteristics (planned schedule). In practice the schedules are not followed and users mostly over-irrigate their fields (the actual schedule). In this paper a simulation–optimisation model is used to develop two alternative (proposed) schedules based on full irrigation and on optimised deficit irrigation within the framework of area-proportionate water distribution, taking heterogeneity into account. As a case study, the allocation and water delivery plans were obtained for one irrigation scheme for the actual, planned and proposed schedules and compared using the simulation–optimisation technique. This showed that the proposed schedule for deficit irrigation had the maximum monetary productivity (total net benefits) and area productivity (irrigated area) and that the equity of both proposed schedules was much higher than those for either the planned or actual schedules. The proposed schedules can be adopted within the framework of the existing system of water distribution, which shows that there is considerable scope for improvement in the performance of existing irrigation schemes without major capital investment.

“…However, the mismanagement of irrigation infrastructure development in India is a long‐standing issue with multiple factors contributing to it. The lack of proper planning has impeded the development and resulted in inefficient irrigation systems; this has led to a situation where a sizeable portion of the country's land suitable for cultivation remains underutilized due to a lack of access to irrigation (Pike, 1995). Overall, the mismanagement of irrigation infrastructure development in India is a complex problem that requires a multifaceted approach.…”

Improving irrigation infrastructure is important for sustaining food security in developing countries like India. The irrigation potential of a system is estimated at the planning phase using conventional approaches. A mismatch in the irrigation potential planned to be created and the land suitable for cultivation can lead to a gap in the irrigation potential created and utilized, making the scheme unrealistic and uneconomical. This study aims to use geospatial data and geographic information system (GIS) tools to identify land suitable for cultivation when planning an irrigation system. This study was conducted in Telangana State in India, where the projected irrigation potential creation was 5 million ha (Mha). It was observed that the total land suitable for cultivation in the state, considering the soil's topography, and physical and chemical characteristics, is about 6 Mha. Time series of average monthly Normalised Difference Vegetation Index (NDVI) over a 10‐year period was used to identify the critical blocks. The study illustrates how the geospatial data derived from remote sensing and recent GIS tools can aid managers in planning, implementing, and monitoring irrigation projects. The study also demonstrates how long‐term satellite information can be used for regional prioritizationprioritisation for constructing irrigation infrastructure and postconstruction impact assessment. This study was conducted as part of the Young Water Professions (YWP) Training program, which allowed the participants to develop professional competencies and implement their learning in real‐world situations.
