GANGA - EARLIER RESTORATION PROCESS Earlier efforts to restore the Ganga were largely limited to water quality maintenance without giving due importance to other ecological functions. Information on the outcome of the decades of studies on aquatic biodiversity are scattered and needs consolidation. Community participation was not encouraged and the perception and attitude of the local people were not built into the restoration process. Religious beliefs and the livelihood issues of the people were not tackled leading to decline in ecosystem service value of the Ganga. In spite of concerted efforts, desired success in restoring the Ganga River was not fully achieved
VISION & MISSIONS OF NAMAMI GANGE PROGRAMME I. “Aviral Dhara” (Uninterrupted Flow) The flow of water, sediments and other natural constituents of river Ganga are continuous and adequate over its entire length throughout the year. II. “Nirmal Dhara” (Unpolluted Flow) The flow in the Ganga river network is bereft of manmade pollution. III. Geologic Entity Ganga river system is the earth’s creations of ancient times, which may not be reparable if damaged. IV. Ecological Entity Ganga river system is a delicately structured balance between living species and the physical environment, achieved by nature over thousands of years, and vulnerable to irreversible changes.
ECOLOGICAL ENTITY BIODIVERSITY CONSERVATION Develop a science-based aquatic species restoration plan for Ganga River by involving multiple stakeholders 1. Biodiversity conservation and Ganga rejuvenation project with WII 2. Assessment of Fish & fisheries in Ganga river system for developing sustainable conservation & restoration plan with CIFRI 3. Educating Schools and Communities for sustainable actions for conserving habitat of Ganga River Dolphin along Ganga River Basin with CEE
BIODIVERSITY PROFILE OF GANGA RIVER § § § 5 species of Mammals 177 species of Aquatic Birds 27 species of Reptiles 11 species of Amphibians 378 species of Fishes
FACTORS AFFECTING GANGA’S BIODIVERSITY § § § § Reduced water availability Changes in river morphology Water pollution Habitat fragmentation and loss Excessive resource extraction Decline in Prey-base Poaching of wildlife Unsustainable development

P, U. P & Rajasthan Forest Department • Conservation of Aquatic Biodiversity through Community Participation by WII – Ganga Praharies
WHY SHOULD THE RIVER DOLPHIN IN INDIA BE CONSERVED • Baiji extinction in China • Precarious status in Nepal and Bangladesh • India is last stronghold with extant populations in Ganges – Brahmaputra and Re-discovery in Indus basin • An excellent indicator of riverine ecosystem health • Unique riverine species with echolocation abilities • Friend of fishermen • National Aquatic Animal
OPPORTUNITIES FOR RIVER DOLPHIN CONSERVATION IN INDIA • Namami Gange Programme • Mo. EF’s Programme for Wildlife Outside protected areas • Focus of International Conservation organizations • Increased Awareness of research institutions and academics on aquatic fauna • International Convention obligations • Iconic status
