IWRM in practice on a basin level

Joakim Harlin, UNDP New York
Co-operative effort by the
Governments of Zimbabwe
and Mozambique.
Implementing agencies:
ZINWA-Save (Zimbabwe)
ARA-Centro (Mozambique)
Supported by a team of local
and international consultants
lead by SWECO International.
February 2002 – February 2006
Financed by the Swedish
International Development
Co-operation Agency
Development of the Pungwe River Basin Joint IWRM Strategy
Project Objectives
The project aims to create a framework for the sustainable and equitable management, development and conservation of the water resources of the Pungwe River Basin, with the objective of increasing the derived social and economic benefits for the people living in the basin.
In short: To develop a joint IWRM strategy and build capacity for its implementation and upgrading
31 151 km2 catchment area of which 95 % in Mozambique and 5% in Zimbabwe
Mean natural annual runoff of about 133 m3/s of which 25-30 % from Zimbabwe.
Minimum flow ~ 4 m3/s, maximum >3000 m3/s
Population: 2003 - 1,2 million 2023 – 2,0 million
Urban centres: Beira - 400’, Gondola – 190’, Nhamatanda –140’
Widespread poverty – 75% of rural households below income for basic needs
Diarrhoea and cholera common due to unsafe drinking water
About 20% of the population HIV positive
Agriculture: Tea, coffee, sugarcane, maize
Tourism: Nyanga and Gorongosa national parks
Rich biodiversity, wildlife, fish and shrimps
The Pungwe River … a few facts
Project phases
• Inception Phase• Monograph Phase• Development Scenario Phase• Joint IWRM Strategy Phase
The Monograph Phase
• Improving the knowledgebase for the development of the water resources through 13 sector studies
• Building of database, GIS and data exchange platform
• Field surveys and data collection
• Training and transfer of technology (hydrological models and GIS)
• Institutional support and capacity building
• Stakeholder communication and participation (basin committee)
SECTOR STUDIES
Surface water
Gauging networks
Groundwater
Dams and other
hydraulic works
Water quality and
sediment
Pollution
Water supply and
sanitation
Irrigation and forestry
Fisheries
Conservation areas,
wildlife and tourism

Infrastructure
Socio-economy
Development Scenarios … investment planning
2005, 2015, 2025: Constrained or un-constrained demand?
Demand or supply driven? Who's demand?
Dams - small, medium and large for hydropower, agriculture, flood and drought mitigation, control of saltwater intrusion, fishing, recreation & tourism.
WRYM modelling to asses effects - available yield from the various alternatives.
Development Scenarios … benefits?
Socio-economic and environmental screening. Technical, financial and economic analysis. Ranking.
Stakeholder consultations –client / basin committees
Joint development of supporting infrastructure e.g. transport, marketing and trading mechanisms
bb1. Benefits to the River
2. Benefits from the river
3. Reduced costs and tension
4. Benefits beyond the river

Economic Development
Social Equity
Environmental sustainability
IWRM strategy? The process of establishing:
• An improved knowledgebase
• An agreed set of sustainable investmentprojects – implementation plan for theprioritised investments
• Active stakeholder participation (basincommittees)
• Institutional capacity to manage, implementand upgrade
• Management instruments - gaugingnetworks, water allocation procedures,information systems, models, water demandmanagement and economic instruments
• An enabling environment for joint IWRM -national and international co-operation(cross-sectoral), information sharing, watersharing agreement
2) Typical issues, constraints and needs
Pungwe and others..
Water resources vary in time and space ...
B13 Eskdale, Matabeleland, Zimbabwe
Flow gauging stations ...
River flow data
Precipitation data
Environmental problems, pollution ... little data
Biodiversity … knowledge – even less data!
”Technical needs” to enable water management
Functioning gauging networks
Technology adapted to scarce data access and to the ability to use and develop this technology–technical, staffing and funding resources.
Lack of hydraulic infrastructure – dams, canals pumps etc.
- Inability to monitor and enforce (quantity and quality)
- Inability to forecast, warn and regulate flows
Institutional and Governance constraints, e.g…
Inadequate management and want of common goals
Unclear definition of functions and responsibilities
Lack of and/or change of qualified staff
Understanding of IWRM – capacity building
Insufficient and/or unclear funding
Revenue collection – willingness and ability to pay for raw water?
Hidden agendas, corruption
Political and macro-economic factors
Poor coordination on all levels!
Transparency with plans and information?
Water allocation and permit procedures?
Willingness and ability to share data?
Differences in legislation
Connection with decision makers?
Stakeholder participation, some reflections..
• What are the incentives for stakeholders to be involved in IWRM – local, basin, national and international?
• Legal rights – empowerment of weak stakeholder groups? Are the Authorities willing?
• How involve stakeholders in investment planning, collection of water tariffs and levies and monitoring and enforcement of water permits? Water a free commodity?
• Establishing stakeholder participation e.g. basin committee / water user associations - takes time and is very input demanding!
