MUS Network Meeting 22-23 November 2010 The Hague MASSMUS Guidelines for Assessing MUS in Irrigation Systems Daniel Renault Senior Officer Land and Water Division FAO
The MASSCOTE Guidelines Family for Auditing Irrigation Management: • MASSCOTE Mapping System and Service for Canal Operation Technique.
MASSLIS for Lift Irrigation System MASSPRES for Pressurized systems (under development).
Major Advances for MUS (last 3 years) 1> MUS is not marginal this is the norm SUS are marginal !! [FAO survey of 30 systems only 2 are Single uses] 2> MUS is better understood within the IWRM framework principles and concepts. 3> MUS is better conceptualized !!

MASSMUS Guidelines The guidelines = RAPMUS-Sheet ; FAO IDP Report ; Set of lectures. Document completed. Available as pdf. to be published early 2011. Applications: Naryanpur India – Vietnam BHH – China Shanxi FID Next: Western Delta Krishna India - China South.

Conceptualization of MUS in large irrigation systems Irrigated agriculture supply water to the natural ecosystems: irrigation practice provides/supports ecosystems services Productive-plus = ecosystem services provider
Millenium Ecosystem Assessment (MEA) Grid to group ecosystem services
Service Providers Direct path Service Receivers Provisional services Direct Service Indirect path Service domain considered All types of services Service Providers ECO-SYSTEM Service Beneficiaries Service Ecosystem Services MUS ? in large irrigation systems
Command area considered from a bio-physical perspective as an agro-ecosystem providing critical ecosystem services to people • A dynamic organic relationship between provider and users of services. • In short a business service model intervening on a large ecosystem serving multiple uses
Defining services in practice ? Domestic from WHO and UNICEF (Howard and Bartram, 2003) assessment in which they estimated that “one-sixth of humanity (1.1 billion people) lacked access to any form of improved water supply within 1 kilometre of their home”. Type of improved and unimproved water supply according to the JMP.
STEP 1 RAPFirst question: Degree of MUS ?One answer is number of MUS reported • Irrigation • Flood control • Drainage • Domestic • Environment • Industry • Recreational • ....
India Karnataka: domestic uses India Karnataka: animals and laundry
Urban uses of irrigation water Urban wetlands in Taiyuan city Urban parks in Taiyuan city
Degree & Integration of MUS 20 systems studied
STEP 2 CAPACITY & SENSIVITY Problems for providing the SERVICES Service? Raw water ? physical Access? Distance to water?
100 % Share of benefits generated Share of water used Share of cost of MOM WBC shares per service: Water, Benefit & Cost
STEP 4 Sizing MUS: Water & benefit shares • WATER ACCOUNTING • VALUING WATER
Water shares • Quantum of use, especially consumptive use • Quality dimension • Energy dimension • Partitioning of non process–use: ex. evaporation from same water body vs tourism, environment, fisheries, flood protection. • Function/service with no consumption (e.g drainage, flood protection)
Ex. FENHE irrigation district Shanxi Province: water balance
Share of benefits • Definition of benefits of water service ? • Usually benefits = Monetary (gross production) for agriculture ! or any productive activity as electricity, fishery, etc... • Domestic ?? Households served for domestic, • Environment ??? • Jobs for small business,
Critical Issues ? • References: building up a database ! • Methodology: MASSMUS rapid appraisal for mapping benefits • Testing the Valuing methods for in depth MUS studies ?
REFERENCES ?VALUE ($) = 22.5 A^0.36 [A= size in m2] After Renwick et al , 2007
STEP 5 Share of COST of MOM • Specific cost to produce the service. • Deliveries, water level, access to water, ensuring a specific function, etc...
Share of COST of MOM Specific costs to produce each service. • Services: Water Deliveries - Support to raw water surface – Groundwater recharge – Control of water • Investment – Operation – Maintenance
Comparative advantage of MUS • Water multi-use: “More DGs per drop”. BUT re-use of water drops is no exclusivity of MUS therefore the specificity of MUS needs to be well documented. • Cost-efficiency:“MUS better than Σ SUS”numerous services to a greater number of users with the same infrastructure more cost-effective than achieving the same with single use systems. • Provision of extra services: ecosystems services provided by MUS systems for which little or no alternatives exist • Externalities: “MUS = positive externalities”YES BUT we should not forget the negative ones !!
What Services & what Operation • Supply water to a delivery point • Control water presence in water stream and bodies • Control water level in water bodies • Control water recharge in surface and groundwater systems • Maintain water quality in natural streams • Maintain the capacity for storing water and control floods
Service? Raw water ? physical Access? Distance to water?
DISTANCE Accessible canal/ drainage/river Groundwater access Permanent surface water body Access
Main Canal 3 km Secondary Canals Tertiary Canal Drainage Example of zoning around the canal infrastructure for Shahapur Canal – Right blue Main and secondary canals – Left red with tertiary canals considered – Drainage network.
STEP 7 MANAGEMENT • Institutional Organization • Spatial organisation
