argument for new ways of managing mega irrigation systems

1. MULTIFUNCTIONAL GOVERNANCE
AND WATER RIGHTS IN IRRIGATION
SYSTEMS

2. 1. Utility providing water in timely and efficient
manner to farmers
2. The basis for the agricultural economy
3. Main part of the physical landscape
WHAT IS IRRIGATION?

3. SIZE OF THE SYSTEM MATTERS
OBJECTIVE MATTERS
IRRIGATION HYDROLOGY MATTERS
RELATION TO LARGER ENVIRONMENT MATTERS
POLITICAL CONTEXT MATTERS
WHAT IMPACTS GOVERNANCE

4. GOOD GOVERNANCE OR
EFFECTIVE GOVERNANCE
“the process by which water resources
are managed through the application of
responsibility, participation, information
availability, transparency, custom, and
rule of law. It is the art of coordinating
administrative actions and decision
making between and among different
jurisdictional levels
or
“ the process of achieiving fair
objectives for water resource use
and development – including the
positioning of different stakes and
interests’

5. PRINCIPLES
• Having a mechanism for prioritization
• Ability to deliver stated goals and be at least ‘problem
and action oriented’
• Cooperation and engagement of active and informed
water users and potential polluters
• Integration with other domains that effect water such
as land use management
• Based on effective mechanisms: finances, functioning
legal system, evidence based monitoring,
communication
EFFECTIVE WATER GOVERNANCE

6. •BALANCED AND PRIORITIZED NEEDS
•BALANCED FUNCTIONS
•SECURITY AND SUSTAINABILITY
•INTEGRATED DIFFERENT WATER SOURCES
EFFECTIVE GOVERNANCE OF
IRRIGATION SYSTEM

7. IWRM IN IRRIGATION

11. MULTIFUNCTIONALITY

12. • Direct use of the water
• Direct use of the infrastructure (dam, storage,
canal and embankments)
• Effect on the hydrological environment
– Moisture/ dryness of top soil
– Shallow groundwater
– Recapture of excess surface water
• Effect on public health
MULTIFUNCTIONALITY OF IRRIGATION
AND DRAINAGE SYSTEMS

13. MULTIFUNCTIONALITY OF IRRIGATION
AND DRAINAGE SYSTEMS
1. Water for crops
2. Controlling water table for agricultural production
3. Domestic water supply
4. Washing functions
5. Livestock water supply
6. Fisheries
7. Industrial water supply (including brick killns)
8. Energy generartion (hydel, water mills)
9. Firefighting resources
10. Water supply to other users
1. Increased property values of land near water fronts
2. Leisure opportunities – water based recreationl
3. Local navigation
4. Use of canal and drain bank for tree cultivation
5. Defense lines
6. Use of canal and drain banks for transportation (embankment roads)
7. Effluent disposal
Direct use of water
Direct use of
infrastructure

14. MULTIFUNCTIONALITY OF IRRIGATION
AND DRAINAGE SYSTEMS
18. Improving land accessibility
19. Reduced damage to built up property by controlling soil moisture
20. Improving soil chemistry
21. Buffering water stock for drought periods (groundwater)
22. Improved protection against floods
23. Generating water for reuse
24 Greenhouse gas emission
25 Miceo climate
26 Land comsidlation or reclamation
27 Aquatic diversity
28. Incidence of water borne vector diseases (human, liivestock)
29. Environmental sanitation and healthy/ clean environment
Hydrological
environment
Public
health

15. Canals and drains serve many
functions and their management is
essential for the livelihoods of all
stakeholders in the area

16. Drinking water
Fishery
Industry
Agriculture
Groundwater recharge
Etc
Many stakeholders

17. • FUNCTIONS
• VALUES
• STAKEHOLDERS

20. DO THE SAME FOR GROUNDWATER

21. • STAKEHOLDER ENGAGEMENT
• TECHNICAL MANAGEMENT
• FINANCES AND ADMINISTRATION
