  1. Thursday, February 5, 2015 Le Meridien Hotel New Delhi Workshop on Environmental Flows for Strategic Planning for the Ganga Basin Session 3: Ganga River Basin – Values and Environmental Flows An Ecosystem Services Perspective

  2. Ganga River Basin Management Plan GRBMP

  3. Ecosystem Services • Provisioning Services or Productswhich are visible and tradable items such as food, freshwater, fiber and energy; • Regulating Servicese.g. flood attenuation, groundwater recharge, ingress of sea, prevention of salt water intrusion; • Supporting Servicese.g. nutrient recycling, soil formation, biodiversity maintenance; and • Cultural Services e.g. recreation, spiritual fulfillment

  4. Most Sensitive Sectors Agriculture & Food Security Diseases & Healthcare Water Supply, Sanitation & Industrial Pollution River Health Energy Health of Water Bodies Ecosystem Services

  5. River Health • Eco-Hydrology • Ecology - Biotic • Ecology – Abiotic • Hydrology • Water Quality and Pollution • Sediment • Socio-Cultural • Socio-Economic • Eco System Services – Use and Non Use or Tangible and In-Tangible

  6. Biodiversity of River Ganga Synthesizes three major eco-regions of India situated along different climatic gradients • the Himalayan mountainous region in the upper reach, • the Gangetic plains in the middle reach, and • the estuarine region (including the Hooghly-Matlah delta) in the lower reach

  7. Indicative Biological Profile of Different Stretches of River Ganga

  8. Indicative Biological Profile of Different Stretches of River Ganga

  9. Indicative Biological Profile of Different Stretches of River Ganga : A couple of brown trout Salmotruttafario were cited by Nautiyal (2007); D* G* BG*= Diatoms, Green algae, Blue green algae; RET= Rare, Endangered, Threatened; IMC= Indian major carps; CF= Cat fishes

  10. Threats to Biodiversity of River Ganga • Habitat Fragmentation • Habitat Shrinkage • Habitat Alterations • Habitat Pollution • Habitat Invasion by Alien Species • Habitat Encroachment • Habitat Disturbances • Habitat Malnutrition

  11. Ecosystem Services: LossesDecline of Fish Catch per km at Allahabad between 1950 to 2010

  12. Typical 10 Daily Hydrograph River Health Marginal to Poor or Dead Excellent to Very Good Very Good to Marginal

  13. E-Flows and River Health • Scientific and Social Aspect or Only Scientific • E-Flows Only for Hydropower and not for domestic, industrial and agriculture • Highly Modified and Near Pristine • Perennial and Seasonal Rivers • Perennial to Seasonal Rivers • Seasonal to Perennial Rivers
