1 Remote Sensing and GIS for Forestry Interventions for Ganga (ForGanga) Implementing Institute Forest Research Institute, Dehradun

2 Ganga: Glimpse of Few Issues

3 Ganga: Glimpse of Few Issues

4 Objectives of the ForGanga DPR Identify appropriate forestry interventions for Ganga rejuvenation that are consistent with stakeholders concerns Suggest implementation plan through a blend of riparian forestry interventions and catchment area treatment Anant Van: Manintaining vegetation cover across the stretch of river Ganga and its tributaries Aviral Dhara: Maintaining minimum ecological flow

5 IV tiers of Filters I. II. III. IV. Micro-organisams and water hyacinths

6 DPR Preparation Stages Concept note submitted to NMCG: 29 th Oct, 2014 Project approved by NMCG : 16 th Feb, 2015 Draft Report Submitted: Feb, 2016 Final Report Submission: March, 2016 (DPR for Phase I) States identified for the Phase I Uttarakhand Uttar Pradesh Bihar Jharkhand West Bengal

7 DPR Preparation Stage: Phase I

8 DPR Preparation Stage: Phase I Development of interactive dynamic webpage

9 DPR Preparation Stage: Phase I Development of interactive dynamic webpage

10 DPR Preparation Stage: Phase I State level Consultations for the States of Uttarakhand Uttar Pradesh Bihar Jharkhand West Bengal Followed By National Level Consultations

11 Forest Cover Status in the Project Area Forest Cover (ISFR, FSI)

12 Geographical Area For Prioritisation Geographical Area (Km 2 ) UK : UP : Bihar : Jharkhand : WB : 88752

13 Actions identified for ForGanga Treatment of Ganga catchment by forestry intervention Treatment of riparian area by different tiers of filters Development of artificial wetlands for treatment of wastewater Biodiversity conservation in Eco sensitive zones of river catchment Development of ecotourism and livelihood opportunities Monitoring plan to review progress of each of the above activities Required information: 1. Identification of critical areas for implementation of each of the above action plan. 2. Identification of local potential native species (by FRI and SFDs) 3. Identification of point and non point sources of water pollution (SPCBs)

14 Few Issues raised in State Consultation Meet Land availability : Agriculture and Encroachment in riverside Silt deposition which effects river flow and cause frequent flooding Fluctuating and meandering river course and thus leave vast areas inundated/water logged for longer periods of time Shifting of river course: The main river course has shifted towards North Brick Kilns results wastelands: A serious need of restoration through Forestry interventions Sand Mining: Need for evaluation of sand mining limits Pollution

15 Few Issues raised in State Consultation Meet Problems associated with adequate capacity and functioning of Sewage Treatment Plants (STPs) Loss of Biodiversity: Aquatic biodiversity needs systematic monitoring Zooplanktons found infested with cancerous growth (Herniation) due to deterioration of water quality Ground water depletion: Due to improvised irrigation/agriculture practices and lack of rain water harvesting systems Unplanned river embankments and flood management Human Interferences of Ganga : How to neutralise Natural Wetlands: are under conflict of protection and ecotourism Different Ghats along the Bank: Highly populated

16 Suggestions Received During Meet Formation of Forest Management Group (FMG) and Riparian Zone Management Group (RMG) FMG: Its role Identification of priority areas for forestry interventions Identification of Species to be planted How to associate community actively Dealing with critical issues of proposed forestry interventions RMG: Its role Identification of priority areas of riparian zone treatment Managing activities which are deteriorating riparian zones Intervention through applicable riparian zone treatment models Riparian zone treatment through biological filters, microbes, plants Construction of artificial wetlands

17 Feedback During National Meet Restoration of wasteland resulted from Brick Kilns along the dead river courses by plantation of grass and suitable plant species Soil quality testing for selecting desired plant species for identified areas The area exposed due to meandering of Ganga towards North should be declared as reserved and restricted area and it should be used only for afforestation Construction of artificial wetland for wastewater treatment and green scape. Development and management of natural wetlands since they are interconnected with Ganga Implementation of Horti- forestry, Agro forestry Models in identified areas Creation of Natural embankment by Bamboo and other suitable species which are good soil binder to check erosion. FRI will facilitate in suggesting species. Creation of check dams, contour bands to check erosion for enhancement of percolation rate Eco- sensitive Zone identification and its management Banning fishing in spawning season and capacity building of fishermen Establishment of riverside parkland, electric crematorium, incinerator for solid waste treatment, bambosetum, arboratum, woodland Plan for managing symbolic immersion of idols and Puja wastes and mass awareness for Ganga rejuvenation

18 Suggested Strategies Treatment of banks of the river by site specific models by delineating actual sites of treatment considering its size, drainage, soil type, public demand, etc. Deciding appropriate width of Aquatic Zone, Riparian Zone, Influence Zone Detail plan to deal with various legal and policy issues of: Encroachment of river beds/ banks Frequent fluctuation of river course Uncontrolled sand mining Presence of brick kilns along river banks and at times along waterlines Excessive fishing and unplanned fishing Steps for habitat improvement for biodiversity conservation with introduction of those mega species which have dwindled sharply like Turtles and Tortoises, Water lizards, Otters, Gharials, Muggars etc. Restoration and conservation of natural wetlands Decentralized artificial wetlands Monitoring plans to review progress of implementation works Developing essential GIS layers and integration of available layers developed by various agencies
