Some key questions and issues: • What is our understanding of integrated catchment
management? • Is it our business? • What are the success factors?

1. UNDERSTANDING INTEGRATED WATER MANAGEMENT (IWM)
• IWM versus ICM • Core IWM streams and dimensions:
• Outcome/developmental agenda • Extended water governance model and approach:
• Infrastructure plus operations and maintenance • Life cycle • Value chain • Governance, programmes, technology • Business principles
• International water management • Alignment of water management actions • Spatial: supply; catchment • Sector mobilization, partnerships and accountability
1.1 ULTIMATE WATER OBJECTIVE
‘The care of human life and happiness and not their destruction is the first and only legitimate
object of every good Government.’

MANAGING WATER WITHIN A DEVELOPMENTAL AGENDA
• Responding to and align with National Development Planning Process and Macro Strategies
• Post 2015 Water Agenda (SDGs) • Centralizing water as a strategic and critical
developmental resource • Establishing sector partnerships and sector
accountability • Introducing integrated planning and integrated
governance • Introducing sector water footprints (social,
economic and environmental)

1.4 INTERNATIONAL CONTEXT: WATER RESOURCE IMPLICATIONS
• Four of our main rivers are shared with 6 neighbouring countries.
• International basins cover 60 % of SA land area. • Contribute 45% of country's total river flow. • These areas support ± 70% of gross domestic
product and similar proportion of population. • Several international inter-catchment transfers and
inter-country systems have been introduced (including LHWP).
• International liaison: • Neighbouring States & SADC • AFRICA (AMCOW) • Global

2. WATER CHALLENGES
• Water availability • Water security • Water quality and pollution • Health • Ecosystems • Urban river utilization (green corridors and lakes) • Operations and maintenance/functionality • Social and equity issues • Cost and viability • Disaster management • Climate change

3. INTEGRATED CATCHMENT MANAGEMENT: WATER MANAGEMENT APPLICATION
• Hydrology and run-off • Resource development • Systems management and optimization • Water quality management (pollution management) • Ecosystems management • Recreation • Disaster management (floods) • Resource integration • Water quality and quantity integration • Land use and water management • Conflict management • Participatory management • International management (shared rivers)

INTEGRATED CATCHMENT MANAGEMENT: URBAN HYDROLOGY
• Increased run-off • NB: water balance • Storm water management • Disaster management (floods) • Water Quality management • Ecosystems • Recreation • Resource development and ownership (dams) • Systems management • Systems hydrology: Sabie Catchment – 80% of run-
off in upper 20%, all base flow in upper 85%

4. DWA ACTION
• Formal water management approach • Establishment of 9 Water management Areas • Establishment of 9 Catchment management
Authorities • Need for Catchment Forums acknowledged • Complex structure and levels

5. SECTOR INVOLVEMENT: IS IT MY BUSINESS?
• Sector includes users, impactors, public, Municipalities, civil societies, impactees, facilitators and sponsors
• Why is it my business? • User of water: need water efficiency • Impactor: run-off, water quality, volume, land-use
management • Impactee: volume, flow, pollution, floods, health, aesthetics,
economic • Manager: land-use, water quality, use efficiency and planning • Resource manager and developer: implications • Water accountability • Conflict management • Enabler • Participatory management • Water culture and ownership
