1 Sabie River Basin, South Africa Integrated River Basin Management by Gutewelt & Partner Katharina Schulthess & Lara Widmer June 2016

2 Where are we? Crocodile Sabie Komati Maputo Indian ocean Sabie river basin = tributary of Komati

3 Transboundary management issue

4 Catchment sections and water use South Africa Injaka Dam Krüger National Park Mozambique Sabie town Corumana Dam Household use drinking water Agroforestry extinguish fires Agriculture irrigation Tourism luxury, pools, golf courts Part of the natural environment Permits great biodiversity Dam supply Drinking water & Electricity for the region down to Maputo

5 Environmental situation with natural buffer zones South Africa Injaka Dam Krüger National Park Mozambique Sabie town A River type Biodiversity Water quality Regulatiorry system Socioeconomic system B Corumana Dam all year flow, big variability with 1/100 yearly floods and droughts, e-flow most biodiverse river in South Africa buffer zones (A,B) help natural self-purification Transboundary, different interest zones big inequalities and unemployment

6 Environmental situation with natural buffer zones South Africa Injaka Dam Krüger National Park Mozambique Sabie town A River type Biodiversity Water quality Regulatiorry system Socioeconomic system B Corumana Dam all year flow, big variability with 1/100 yearly floods and droughts, e-flow most biodiverse river in South Africa buffer zones (A,B) help natural self-purification Transboundary, different interest zones big inequalities and unemployment

7 Environmental Flows Water Quality in Rivers and Lakes Sustainability Issues & Water Management Considerations Integrated river basin management

8 General objectives Ensure river diversity and allow natural fluctuations Research the resilience of river and tributaries Flow regime: 70% at min 3.5 m3/s 8-10 flood events/y Allow droughts Allow natural variability of the ecosystems and secure the livability of local community Get acknowledgement for the biodiversity of the Sabie river Water security Presence in tourist guides, Research collaboration List 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 prosperity Decrease unemployment to 50% by 2030 and to 25% by 2040

9 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

10 Stakeholders User association SA chatchment inhabitants MB chatchment inhabitants SA chatchment foresters MB Corumana dam management SA chatchment farmers SA Injaka dam management Krüger National Park management Tourism association (outside KNP)

11 Management plan

12 Environmental flow

13 Flow dependent indicator species Invertebrates Fish Mammals Riparian plant species

14 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)

15 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)

16 Sanitation Composting chamber Human excreta Kitchen waste (organics) compost can be used for agriculture

17 Agriculture & Forestry Employment of people Support local community Self-supply Supply of eco-hotels raise awareness of people (workshops) Microcredits or co-subsidies for funding enhance awareness of conventional tourism sector

18 Ecotourism Increasing and promising tourist sector Employment of people Development of new tourist sector Include local work and products Increase employment invite people with experience and organize workshops microcredits for funding

19 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

20 Research & Education Historical research work and data Continue research unique example of long-term knowledge and systems understanding

21 General objectives & Conclusion Allow natural variability of the ecosystems and secure the livability of local community Ensure river diversity and allow natural fluctuations Research the resilience of river and tributaries Get acknowledgement for the biodiversity of the Sabie river Water security Promote green growth (population growth & land use) Enable economic prosperity Flow regime: 70% at min 3.5 m3/s 8-10 flood events/y Allow droughts Presence in tourist guides, Research collaboration List of measures for drinking water supply and flood protection Level and understanding of sustainability of new businesses Decrease unemployment to 50% by 2030 and to 25% by 2040 Conclusion Feasible Great potential Holistic approach with all stakeholders included Overcome transboundary problems and increases potential for national cooperation Serves as model catchment Increased health and security Increased employment and livability
