Sustainability Issues & Water Management
Considerations
Integrated river basin
management
Environmental Flows
Water Quality in Rivers and
Lakes
Allow natural variability of the ecosystems and secure the
livability of local community
Ensure river diversity and allow natural fluctuations
Flow regime: 70% at min 3.5 m3/s 8-10 flood events/y
Allow droughts
Research the resilience of river and tributaries
Get acknowledgement for the biodiversity of the Sabie river
Presence in tourist guides, Research collaboration
Water securityList of measures for drinking
water supply and flood protection
Promote green growth (population growth & land
use)
Level and understanding of sustainability of new
businesses
Enable economic prosperityDecrease unemployment to 50% by 2030 and to 25% by
2040
General objectives
Live cycle of our management plan
Assessment and Stakeholder Involvement• User
association -> decision making body
• Sets goals and objectives
Active facilitation of the process, participatory planning• Sustain e-flow • Collaboration ->
knowledge transfer & capacity building
• Experienced partners around the world
Advisory phase • Implementation• Monitoring
Exit strategy • Elected local
management team takes over

Flood protection & Droughts
WUA: • Interconnectivity (information about
incidents)• Integrate needs of up- and
downstream users
Flood events• Construction zones• protection by floodplain management• Ensure drinking water
Droughts• Ensure water supply (Injaka dam)
Water supply & treatment and sanitation
Water supply• in towns: extend existing system to a
centralized distribution• rural: treatment on household level
Water treatment and sanitation• waterless toilet facilities (e.g.
composting chamber)
Sanitation
Composting chamber• Human excreta• Kitchen waste (organics)
compost can be used for agriculture
Agriculture & Forestry
Employment of peopleSupport local community• Self-supply• Supply of eco-hotels
raise awareness of people (workshops)Microcredits or co-subsidies for
fundingenhance awareness of conventional
tourism sector
Ecotourism
Increasing and promising tourist sectorEmployment of peopleDevelopment of new tourist sector• Include local work and products• Increase employment
invite people with experience and organize workshops
microcredits for funding
Research & Education
Education in school about importance of biodiversity and natural variability
Cooperation with University of Johannesburg (UJ)• Monitoring of flow and indicator
species• New research on ground water and
water quality
model catchment for sustainable development in South Africa
Research & Education
Historical research work and dataContinue research
unique example of long-term knowledge and systems understanding
Allow natural variability of the ecosystems and secure
the livability of local community
Ensure river diversity and allow natural fluctuations
Flow regime: 70% at min 3.5 m3/s 8-10 flood
events/y Allow droughts
Research the resilience of river and tributaries

General objectives& Conclusion
Conclusion• Feasible• Great potential• Holistic approach
with all stakeholders included
• Overcome transboundaryproblems and increases potential for national cooperation
• Serves as model catchment
• Increased health and security
• Increased employment and livability
