ONR-003 IGNOU Solved Assignment 2026-27

Course Scope and Syllabus Overview for ONR-003: Water Harvesting, Conservation and Utilisation

ONR-003: Water Harvesting, Conservation and Utilisation is a core component of IGNOU’s Certificate in Water Harvesting and Management (CWHM) under the School of Agriculture, designed to equip learners with practical and theoretical expertise in sustainable water management. This course bridges ecological principles and engineering applications, addressing critical challenges like drought resilience, soil moisture retention, and efficient irrigation systems. Through structured academic modules, students explore innovative techniques for rainwater harvesting, groundwater recharge, and watershed management, ensuring alignment with global and national water conservation policies. The syllabus emphasizes hands-on learning, enabling graduates to contribute meaningfully to rural and urban water security initiatives.

Key Syllabus Units and Topics

• Block-1: Water Harvesting Techniques: Covers traditional and modern methods such as rooftop harvesting, contour bunding, and percolation tanks, with a focus on their design, implementation, and environmental impact assessments.
• Block-2: Water Storage and Conservation: Examines structural solutions like check dams, earthen tanks, and lined reservoirs, alongside non-structural strategies like afforestation and soil conservation practices to maximize water retention.
• Block-3: Utilisation of Harvested Water: Analyzes agricultural, domestic, and industrial applications of conserved water, including drip irrigation systems, wastewater recycling, and sustainable livelihood integration.
• Block-4: Policy and Community Engagement: Discusses legal frameworks, government schemes (e.g., MGNREGA), and participatory approaches to water management, fostering community-led conservation efforts.
• Block-5: Case Studies and Field Applications: Evaluates real-world examples from India and globally, emphasizing scalable solutions for arid and semi-arid regions within the CBCS curriculum.
