SS1-Rejuvenation of river Ganga- from Planning to action Ground- Surface Water Interface D.P. Mathuria Executive Director (Tech.) Ground and surface water linkages • Surface water and ground water are linked as component in hydrological-ecological system • Abstraction from and Surface Ground contamination of either one will flow water affect each other. • During lean season flow in streams is augmented by Ground water. River Ganga (Rejuvenation, Protection, Management) Authorities Order, 2016 Principles to be followed specifies: • The integral relationship between the surface flow and sub-surface water (ground water) shall be restored and maintained. • The bank of River Ganga and its flood plain shall be construction free Zone to reduce pollution sources, pressures and to maintain its natural ground water recharge functions Aquifer mapping in parts of Ganga-Yamuna Doab in Kaushambi-Kanpur stretch. Proposed area of extension for paleo channel Mapping • In collaboration with CGWB and CSIR-NGRI, Heli-borne study for A: CGWB approved block A+: CSIR-NGRI extended block of A aquifer mapping with focus on B: proposed area of Extension palaeo-channels B • Location: parts of Ganga Yamuna Doab in Kaushambi-Kanpur stretch. A+ A • Area: ~ 8500 sq.km Previous Study: CSIR-NGRI, under the aegis of DoWR-RD-GR, conducted helicopter borne geophysical survey covering Prayagraj and Kaushambi region led significant findings as: • 3D structural settings of aquifer system • Discovery of a buried paleo channel (ancient river, now underground) that joins Yamuna river at Durgapur village, roughly 26 km south of the current Ganga-Yamuna Sangam at Prayagraj. • Aquifer merging at places due to tectonic activities. • River Ganga has good hydrogeological connectivity with surrounding aquifers How its useful Strong need of Managed aquifer recharge (MAR) where? Groundwater over-exploitation Subsurface linkages for groundwater contaminant migration? declining of water level Knowledge on subsurface connectivity Reduction of between Ganga and Yamuna rivers will Baseflow play very crucial role in planning of Ganga cleaning as well as protecting Reduction in the safe groundwater resources. river water flow Deliverables: • 3D resistivity map with geometrical settings of principal aquifers • Paleo channel map and its 3D catchment of sediments • Linkages between aquifer system including paleo channel and river system Thank You LEARNING FROM BEST PRACTICES IN WATER MANAGEMENTWATER Dr K Yella Reddy, FIE Dean AE&T, ANGRAU and Vice President, ICID EFFICENT USE OF WATER Key for Sustainable Development The Right to Water, a Human Right Challenges and Opportunities ❑ India’s share of resources Water : 4% Land : 2.5 % Population : 17% YEAR POPULATION PER CAPITA AVAILABILITY IN MILLIONS Cu m/year Liter/day 2001 1027 1820 5000 2010 1210 1545 4230 2025 1394 1340 3670 2050 1640 1140 3120 ❑ With 2085 cubic kilometer India stands 7th ❑ Per capita availability wise it is 133rd position Evergreen Revolution Food Requirement by 2050 : 450 MT Improve Overall WUE by : 20% (National Water Mission, GOI) 3 Components of WUE as per CWC Efficiency Values (%) Reservoir Efficiency 95%-98% Conveyance Fully Lined system 70%-75% Efficiency Partially Lined system 65% Unlined system 60% On farm application Sprinkler/Drip 85% Efficiency Irrigation 60% Basin/Furrow Irrigation Drainage Efficiency 80% IPU/IPC 85% Overall WUE 60-65% How to reach Linkage between different water sources in an irrigation system 5 National Water Policy (2012) • Priority on use of water • NWP on impact of climate change • Enhancing water availability for different use • Demand management Project appraisal and environmental impact assessment for water uses to inter-alia include: i) analysis of water foot prints, ii) recycle and reuse including return flows to be a general norm, iii)incentivizing economic use of water to facilitate competition, iv)adaptation to water saving means v) performance monitoring and vi) reclamation of commands from water logging, salinity and alkalinity. • Regulation of water prices • Project planning & implementation • Data base and information needs • Capacity building, research and training needs 6 DUBLIN Principles more relevant now Valuing Water If water is priced at 1 paisa liter (15 cents per cu m), it costs Rs. 1,20,000 (US$2000) for growing paddy in one ha area Matching Irrigation Demand and Canal Supply The engineers of I&CAD Department, officials of Agriculture and Ground Water Department should be offered trainings on a regular basis on irrigation modernisation, crop irrigation requirements including effective rainfall contribution, water budgeting, latest aspects of water measurement and regulation, participatory approaches in water management and woe’s participation in AWM. Water Measurement The engineers of I&CAD Department should install special water measurement structures like RBC flumes as a standard procedure in all their new irrigation projects; the same applies for their modernization projects of existing schemes. 9 Water Saving Crop Production Technologies • Direct seeding / MSRI / AWD for rice in harmony with soil microbial technologies in maximizing the water use efficiency.

It is our moral responsibility to eradicate this hunger from the world and make the food available.

Day Zero refers to the day when a place is likely to have no drinking water of its own. ✓According to the Niti Aayog's Composite Water Management Index (CWMI), Bengaluru, Chennai, Delhi and Hyderabad are among the most susceptible.
