Nivedita Haran, IAS (Retd) 2 Why Public Lands Need Protection
Public lands carry some of the worst-maintained records, tampered with and at times destroyed Public lands best source of buying favours and graft Seldom protests if parks, road shoulders, woods, wastelands, reclaimed lands are taken away; few even notice; after all everyone’s land is nobody’s land Same with water bodies: ponds, tanks, river banks, coast -line, especially in urban areas Unscientific use of such lands and filling up of water bodies cause of urban flood: e.g. Mumbai, Chennai, Kolkata; landslides, e.g. Haridwar Need to set up State Land Bank to: inventorise all public lands remove encroachments, generate public interest groups ; protect ‘public interest’ Use these lands for genuine public purpose

Set up in 2007-08 by a Govt. Order Revenue staff given training and authenticated details in prescribed proforma collected from each Village Officer, Tahsildar, District Collector The data entered centrally in the KSLB computer centre in the o/o the Land Revenue Commissioner Website launched www.kslb.kerala.gov.in Each parcel of land surveyed and geo-referenced spatial map generated Stones (jhendas) to demarcate placed around these lands A Special Land Protection Team created from retired Army jawans and trained who conduct beats to inspect each parcel at least once a fortnight Verification register maintained in neighbouring house, placing responsibility on the public
Nivedita Haran, IAS (Retd) 4 Protection of Rivers – Changing Scenario
Commodity vs ecosystem approach: rivers a source of anthropological, sociological and economic development Re-emphasis on ecological services of water in bio -geochemical and hydrological cycles Understanding the scope of possible trade off Watershed approach : sediment yield and water yield Anthropocentric approach- an organic entity recognising river as an interface between humans and nature Convergence of all stake holders is the primary necessity

Goal: Restore and maintain river health/ ecosystem services Steps Catchment mapping River bank mapping Sediment and drainage discharge Water quality Water and sediment assessment and balance Out put River management plan

Rivers play a very important role in promoting the Kerala model of development with emphasis on PRIs and decentralization; maintaining river ecosystem is of prime necessity Rivers are over-exploited Water demand increased manifold with economic growth River bed mining for granite and sand far in excess of sediment generation Flood plain materials have been removed Water quality of lower and middle lower courses of rivers have deteriorated significantly Human intervention in all segments of rivers have deteriorated river ecology Rivers a danger and source of accidents

Nivedita Haran, IAS (Retd) 9 What was New in This Initiative?
Task –I: Mapping river bank
Objectives: To prepare an inventory of the river bank falling in the midland & lowland segments Methodology : Field mapping using cadastral scale map and high resolution image Data source: Field mapping in cadastral scale & High Resolution Images Output: i) Large scale map showing status of river bank-land use feature, man- made feature and physical feature ii) Attribute Data and iii) Analysis & Report Task –II: Sand auditing Objective: Assessment of availability of sand, Assessment of minable quantity, Setting up an auditing mechanism at regular interval as required by Law
Nivedita Haran, IAS (Retd) Salient and Innovative Features of the Programme 10
A broad-based programme with involvement of Government Departments, S&T institutes, Engineering Colleges, University Departments and NGOs, the youth coordinated by Policy-makers Opens the scope of involving Panchayats and local self Government Institutions in river rejuvenation and management, hitherto not attempted Human scale mapping and gathering of largest possible data base of multiple usability
Blending of traditional mapping and latest mapping technology (RS, GIS, GPS) RIS for transparent and informed decision-making Low cost and easily replicable; can be dovetailed with existing govt programmes Benefits are visible in short time and long-term, covering individual and societal interest Contributes to broad-based sustainability (UNEP Charter )
