  1. PANEL A2TO OUR WORLD: ENVIRONMENT • WATER, ENERGY, WASTE MANAGEMENT • Name: Dr.Nandakumaran P • Designation: Regional Director • Organization: Central Ground Water Board • Email: pnkm62@gmail.com

  2. WATER

  3. WATER AVAILABILITY - INDIA

  4. WATER SCENARIO - INDIA

  5. WATER AVAILABILITY (PER CAPITA)

  6. WATER STRESS & SCARCITY

  7. FRESH WATER AVAILABILITY Total Precipitation : 4000 BCM Total Water Availability : 1869 BCM Total Utilizable Water : 1122 BCM • Surface Water - 690 • Ground Water - 432

  8. ANTICIPATED DEMAND (BCM) In 2010 : 813 710* In 2025 : 1093 843* In 2050 : 1447 1180 * Total Utilizable Water : 1122 (690+432) S.W G.W * With improved management

  9. WATER MANAGEMENT ISSUES • Non-availability of Resource • Sustainability Issues • Inefficient use • Contamination • Climate Change?

  10. WATER MANAGEMENT ISSUES – RURAL AREAS • Low penetration of protected water supply schemes • 30% rural Indian lack access to safe drinking water supplies • Only 7 States have rural areas with full drinking water supply. • Sustainability Issues (‘Slipped back’ habitations) • Neglect of traditional water management practices • O & M Issues ( Lack of technical expertise ??) • Contamination (natural/man-made, poor sanitation) • Inefficient use of available resources.

  11. SUSTAINABLE WATER MANAGEMENT- OPTIONS ??? • Supply Side • New Sources & Technologies • Recharge Augmentation (RWH, Water Conservation) • Better sanitation • Demand Side • Improved water use efficiency • Incentives / Regulation • IEC • Awareness creation • Capacity building of grass-root level stakeholders

  12. ENERGY

  13. Indian Energy Scenario • Over 40% households do not have electricity. • Nearly 1/3rd of our energy is still from non-commercial sources (biomass). • Per capita energy consumption is third and per capita electricity consumption is fifth of the world average. • India faces an enormous demand supply gap of about 11% energy shortage and 14% peak power shortage.

  14. Options ?? • Renewable energy sources • Solar (Photovoltaic /Thermal) • Wind • Tidal • Geothermal • Biomass • Small Hydroelectric schemes • Bio-fuels • Improvement in Energy Efficiency • Improved Storage Technologies • Awareness creation / Capacity building

  15. WASTE MANAGEMENT

  16. INDIAN SCENARIO • Over 50 Million Tonnes of Municipal Solid Waste (MSW) generated per annum. • Per-capita waste generation increasing @ 1.3% & total waste generation @ 5% per annum • Open Dumping is common – No scientific closure of Landfills - Health impact, GHG emissions etc. • Little work done on scientific waste management – waste minimization, reuse, recycling. • Suburban & rural areas worst affected!

  17. POSSIBLE APPROACHES • Waste Management • Minimization • Segregation • Recycling • Processing (Resource Recovery) • Transformation • Sanitary Land fills • Method to be • Technically sound & Financially viable • Environment-friendly • Easy to operate & maintain ( by local communities) • Decentralized ( Processing at source – to the extent feasible) • Sustainable & acceptable to the local community.
