Water scarcity and inefficient irrigation practices are pressing challenges in the semi-arid region of Southern Haryana. The adoptionof modern irrigation technologies—such as drip, sprinkler, and subsurface irrigation—offers a strategic pathway to optimize water use, enhancecrop productivity, and promote sustainable agriculture. This paper explores the integration of these modern methods within the framework ofIntegrated Water Resource Management (IWRM), which aims to harmonize the management of surface and groundwater resources, policyimplementation, and stakeholder participation.Using district-level data from Rewari, Mahendragarh, Bhiwani, Charkhi Dadri, and Nuh, the study identifies current irrigation practices, evaluateswater resource potential, and assesses the socio-economic impacts of technology adoption. Field surveys, government reports, and policydocuments are examined to understand implementation bottlenecks, regional disparities, and institutional mechanisms.The findings suggest that when modern irrigation techniques are embedded within a broader IWRM framework—supported by governmentschemes, local participation, and capacity building—they yield measurable benefits such as reduced groundwater depletion, increased yield perdrop, and climate resilience. The study concludes with a set of region-specific recommendations to achieve sustainable water resource governanceand inclusive agricultural development in Southern Haryana.Keywords: Integrated Water Resource Management (IWRM), Modern Irrigation Techniques, Southern Haryana, Drip Irrigation, SprinklerIrrigation, Groundwater, Sustainable Agriculture, PMKSY, Climate Resilience, Regional Planning
