The Permanent Okavango River
Basin Water Commission
(OKACOM)GEO- UNESCO Joint Workshop on Earth Observation
and Capacity Development for IWRM at River Basins in
Africa
Nairobi , Kenya, January 2012
Tracy S. Molefi
OKACOM –OBSC
Presentation Outline
•Basin Facts
•Institutional Framework
•Challenges and Issues
•Responses from OKACOM’s Strategic
Action Programme
Basin Facts• Transcends 3 countries – Angola
48%, Namibia 37% Botswana 15%
and of basin territory
• Angola 94.5% total run-off in
catchment, Namibia 2.9%,
Botswana 2.6%
• Hydrologically active area of
approximately 323 192 km
• 1,100 km length
• 10 cubic kilometers of surface
water flow to the delta per annum
• Catchment 413,550 km2
• Home to 1,113,000 people
Use of Water in the Basin
•Subsistence agriculture
•Tourism based activities
•Domestic water supply
•Fisheries
•Ecosystems services
•Limited irrigated agriculture
The Commission
• Established in 1994 by the Windhoek Agreement
• Three countries –Angola, Botswana and Namibia
•Acts as a technical advisor to the contracting Parties on
matters related to conservation , development and utilization of
the water resources of common interest in the Okavango
•Secretariat based in Maun, Botswana

EPSMO Project
Transboundary Diagnostic Analysis
•Objective understanding of status of basin resources
•Issues and trends
Strategic Action Programme (SAP)
• To assist framing of issue-responsive programmatic
interventions
• Basin Development Management Framework
National Action Plans NAPs)
The very first OKACOM commissioned project
•Multi-disciplinary and trans-country teams :
Angola, Botswana, Namibia
•Assisted by regional and international experts
•Consultation with local communities and
institutions
The Process : Transboundary
Diagnostic Analysis
The Process : Integrated Flow
Assessment
Understanding of impacts of flow modification on
•Ecological dynamics
•Socio-economic and livelihood conditions
•Overall macro-economics of the basin
Scenario planning : 1, 2 and 3
Concept of acceptable development space
•Negotiation tool for managing trade offs
Summary of expected changes in ecosystem health for the
Low, Medium and High Water-use Scenarios
TDA Areas of Concern and Drivers
driven by
•population dynamics
•land use change
•poverty
•climate change
•variation and reduction of hydrological flow
•changes in sediment dynamics
•changes in water quality
•changes in the abundance and distribution of biota
Issues (TDA Findings)•Placement of abstraction and impoundments will greatly influence flow
variability
•Certain HEP and land use developments will impact sediment transport, which
is unique and important especially for Delta
•Increased Irrigated agriculture poses the greatest challenge
•The planned run-of-river HEP (micro HEP) plans which have little impact on
flow but can affect sediment : no site for major dams
•The two main tributaries (Cuito & Cubango) serve complementary hydrological
functions (development on one can be mitigated by other)
Issues (TDA Findings)
•Water Supply &Sanitation is unlikely to have a significant impact, people will
Angola will rely on direct use for some years
•Distribution of current economic benefits of the river is skewed downstream
•Benefits of future water resources development will start to accrue upstream but
the indirect costs of development will be paid mostly downstream.
•OKACOM has the potential to arrange benefit sharing mechanisms exploiting
significant comparative advantages (i.e. tourism vs. irrigation) and is ideally
situated to drive reform and manage
Challenges
1. Integrated and Coordinated Water
Resources Development and Management
• Inadequate water infrastructure for achieving regional
economic development eg. energy and food security
• Inadequate financing of water resources development and
management.
• Low access to water supply and sanitation
Challenges
2. Environmental Management and Sustainable Development
• Inadequate integrated and coordinated protection and sustainable
development and use of wetlands ( e.g. no management plan for
the basin)
• Ecosystems and related ecological and economic functions in the
basin may be threatened by fragmented, uncoordinated and
unsustainable development.
• Deterioration of water quality due to localised pollution
• Proliferation of invasive aquatic species
Challenges
3. Basin wide Cooperation and Integration
• Limited capacity of national and regional water management institutions
to perform river basin management tasks
• Inadequate water resources knowledge base for basin wide planning,
development and management
• Inadequate effective stakeholder participation in basin resources
development and management.
Challenges
4. Adaptation to Climate Variability and
Change
• Insufficient data and information for adequate climate change
predictions
• Difficulties in managing uncertainties associated with climate
prediction models
• Extreme variability and uneven distribution of rainfall is likely to
be amplified by climate change
• Inadequate of integrated management of extreme events ( flood
and drought ) in development planning
• Inadequate coping mechanisms for climate variability and
change
Current Use of Data in Decision
Making in the Basin
Water-related decisions made on an
annual basis
•For OKACOM, efforts defining
acceptable development space first
steps
Data and models used in making
these decisions
•A variety of systems and models are
being tested, e.g. WEAP
Difficulties encountered in using
these data and models
•Data collection and reporting in the
remote areas of the Angolan portion
of the Basin
Coping with data needs and services
for special events such as floods and
droughts
•Hydrological Data Sharing Protocol
an effort to share and consolidate
data for planning
Basin Plans to Sustainable
Development and a Green Economy
Strategic Action Programme
basin-wide policy framework document for the Cubango-
Okavango river that lays down the principles for
development of the basin and improvements of livelihoods
of its people through cooperative management of the basin
and its shared natural resources

Management Framework (BDMF)
