     District Dewas, Madhya Pradesh
SAMAJ PRAGATI SAHAYOG: AN
              INTRODUCTION
Samaj Pragati Sahayog is a grass-roots voluntary
organisation founded by 8 professionals from
academic disciplines representing various Social
and Life Sciences
Its basic mandate is the empowerment of the
people.
SPS is committed to capacity building and
mobilisation of rural communities for
development.

                           One of the most backward,
Dewas
district
                           neglected and drought-prone
                           tribal pockets of India -- the
           Bagli           Bagli tehsil of the Dewas
                           district, Madhya Pradesh
HOW WE STARTED

• The Dewas Town Experience in 1990

• Severe, man-made crisis of groundwater on account of
  unplanned industrialisation of a small town

• Initial watershed work – Neemkheda ponds

• Lessons learnt on working in different geological settings –
  successes (percolation ponds in recharge areas) and failures
  (irrigation ponds in dolomites).

• Beginning of our collaboration with ACWADAM – which is
  now more than a decade old.
GROUNDWATER AND SURFACE WATER
             BASINS
• Watershed defined as a surface water basin is inadequate

• The notion of groundwater catchment has to be brought in

• The two catchments need not overlap always

• Hydrogeology & the correct location of watershed structures

• Aquifer properties (T & S) are highly variable

• This needs micro-level study and mapping

• The true watershed community is one which shares an
  aquifer
FROM MAPPING TO TYPOLOGIES
• Rock strata do not occur in isolation

• Composite rock strata with varying aquifer properties and
  physical layering gives rise to groundwater typologies

• Typologies are not just physical entities. They go with a
  historically   governed   pattern   of   groundwater     use   by
  communities

• Hence, groundwater typology is a socio-physical category

• The vexing issue of scale: determined by the degree of
  interconnections between aquifers (“zone of interference”)
FROM TYPOLOGIES TO STRATEGIES
• The emerging idea is that groundwater is a community resource

• From this perspective, watershed development involves strategies
  to ensure the protection and the sustainable and equitable use of
  groundwater by the community

• Two key ideas:

• a) separation of Right to Water from the Right to Land – the
  revolutionary idea of Pani Panchayats

• b) distinction between Basic and Economic Service – KR Datye -
  following the principle of “specific egalitarianism” (James Tobin)
FROM TYPOLOGIES TO STRATEGIES
• Using these ideas we work out a scale of priorities for each
  typology (drinking water, water for livestock, protective
  irrigation, irrigation for second crop, other uses)

• To match the priorities, also work out the range of strategies for
  community management of groundwater in each typology

• Not a technical exercise; an exercise in social decision making
  backed by a scientific understanding of water

• People’s Institutions (PRI, VWC, SHGs, FPC) play a crucial role

• Village agreements on the basis of such detailed work

Community Sharing of Wells
TYPOLOGY 1

CHARACTERISTICS
• Hilly, Forested Topography

• Underlain by Hard Rocks (Basalts of Deccan Trap)

• Seasonal Streams Carrying High Runoff

• Low and Uneven Availability of Groundwater

• Small Agricultural Component

• Acute Shortage of Drinking Water: Attempts by PHED, SPS

• Water Quality Issues
TYPOLOGY 1
Section – Typology 1
Protocols for Typology 1


• Top Priority: Drinking Water
• Protection of Recharge Areas
• Limited Water Harvesting in Discharge Areas (the stream)
• Community Use of Water in Groups
• Regulation of Deep Drilling
• No Irrigation Well within 50-75 m of Any Drinking Water
  Source
• Regulation of Cropping Pattern through Agricultural
  Programme
TYPOLOGY 5

• Flat Topography

• Underlain by Dolomitic Limestones (Vindhyans)

• Low Water Availability in the Shallow System

• Variable but High Availability of Groundwater at
  Deeper Levels

• Low Scope for Water Harvesting (High Permeability)

• Rapidly Growing Agricultural Component Fuelled by
  Competitive Drilling of Deep Bore Wells
Protocols for
       Typology 5


• Top Priority: Regulation of Groundwater Overuse
• Ban on Fresh Drilling of Bore Wells
• Regulation of Pump Capacity and Pumping Hours
• Protection of Drinking Water Sources
• Community Use of Water
• Regulation of Cropping Pattern through Agricultural
  Programme
WHAT DOES THIS MEAN FOR POLICY?
• A National Programme on Groundwater Management

• Mapping of Aquifers and Developing Location Specific Protocols

• Groundwater Pilots: Detailed Work in Specific Situations

• Focus on Demand Regulation

• Focus on Community Management and Equity

• Focus on Empowering People’s Institutions

• The Context of NREGA: Fund Availability vs Use

• Methodology of Estimation of Groundwater Potential Need to be
  Changed

Protocols for Typology 1 • Top Priority: Drinking Water • Protection of Recharge Areas • Limited Water Harvesting in Discharge Areas (the stream) • Community Use of Water in Groups • Regulation of Deep Drilling • No Irrigation Well within 50-75 m of Any Drinking Water Source • Regulation of Cropping Pattern through Agricultural Programme
  • 15. TYPOLOGY 5 • Flat Topography • Underlain by Dolomitic Limestones (Vindhyans) • Low Water Availability in the Shallow System • Variable but High Availability of Groundwater at Deeper Levels • Low Scope for Water Harvesting (High Permeability) • Rapidly Growing Agricultural Component Fuelled by Competitive Drilling of Deep Bore Wells
  • 16.
  • 17. Protocols for Typology 5 • Top Priority: Regulation of Groundwater Overuse • Ban on Fresh Drilling of Bore Wells • Regulation of Pump Capacity and Pumping Hours • Protection of Drinking Water Sources • Community Use of Water • Regulation of Cropping Pattern through Agricultural Programme
  • 18. WHAT DOES THIS MEAN FOR POLICY? • A National Programme on Groundwater Management • Mapping of Aquifers and Developing Location Specific Protocols • Groundwater Pilots: Detailed Work in Specific Situations • Focus on Demand Regulation • Focus on Community Management and Equity • Focus on Empowering People’s Institutions • The Context of NREGA: Fund Availability vs Use • Methodology of Estimation of Groundwater Potential Need to be Changed
