Agricultural water management_Dr Kamalam Joseph (The Kerala Environment Congress)_2012

  1. 1. Dr Kamalam Joseph CWRDM Calicut- 673 571
  2. 2. Water requirement 2025 2050Irrigation 557 611Domestic 43 62Industries 37 67Power 19 33Inland navigation 7 10Env./ Ecology 5 10Evaporation losses 42 50Total 710 843
  3. 3. Agriculture is both a victim and aculprit of water shortages anywherein the worldThe water footprint in agri. is large. Onecalorie - 1 litre of waterUpto 70% of water taken from rivers and gwis used to irrigate agricultural landWater use efficiency remains very low withmore than 50% water losses
  4. 4. The water crisis would spiral out of control if not handled in time.The challenges lie in the development of: technological measures managerial measures scientific strategies policy interventions good governance
  5. 5. Rain water managementIrrigation managementDrainage management
  6. 6. System management and water allocationIrrigation methods (surge, micro, cablegation,underground)Deficit irrigationZonationCrop production technologies (croppingsystems, bio-engineering technologies)
  7. 7. System level management strategy (Supplymanagement - Demand management -Demand management by allocated efficiency)Types of management (Participatory irrigationmanagement - Privatisation??? - Publicprivate partnership)Information management (MIS, flexible)
  8. 8. On technological aspects, action research,policy analysis and on HRDLegal & socio-economic aspects of irrigationNetworking and coordination of research ininstitutions
  9. 9. -to increase the econ, physical & mngmt efficiency- focusing on design & devt. of water resources infrastructure from multiple use system perspective- to increase WUE (crop selection, consumption form, food trading, water pricing, incentives )
  10. 10. far, So far, an effective agriculture water policy has not been successful in Kerala- small holding size, lack of measuring control structures, political opposition, lack of respect to equity, no incentive
  11. 11. To investigate how the current approaches towater allocation must evolve to address scarcity,complexity, uncertainty inherent in the systemTo achieve transparency, accountability &protection of broad public interestBring together those who manage and those whoare managedProvide the needed security and flexibility to thewater users - & mitigating any general adverseimpacts on water quality and environment.GG Should start where rain drops fall…….
  12. 12. 1%increase in water productivity in foodproduction makes available in theory- atleast an extra 24 lpcdContinued efforts for improving the waterproductivity and water use efficiency willtake agricultural water management sectorto measured heights without causing anyadverse effect on the other waterdemanding sectorsTherefore, investing in agriculture and inagriculture water management is analternative strategy for freeing water forother purposes and safeguarding theenvironment!!!!
