Group Discussion on Conservation and Ecosystem Services

  1. 1. Trans-boundary Water Management Workshop Group Discussion on Conservation and Ecosystem Services Johannesburg 29-30 April 2014
  2. 2. Content Key challenges Common experiences and lessons Current research and development priorities Contributors for joint papers Partner institutions for future collaborations
  3. 3. Key challenges Balance of development and conservation Common challenges ◦ Secure development and growth Poverty alleviation ◦ Trans-boundary compensation mechanism ◦ Lack of common monitoring infrastructure (different systems in different sectors and countries) ◦ Ecological infrastructure (establishment and management) Paddy fields Artificial wetlands Riparian strips ◦ Uneven distribution of water and climate variability Seasonal (time), space and socially ◦ Water volume and quality management (surface and groundwater) ◦ Infrastructure implications to environmental conservation and ecosystems Environment flow Food security Soil denudation Biodiversity
  4. 4. Common experiences and lessons Africa: balance of development and conservation China: restoration need; West part balance of development and conservation How Chinese investment could help? Specific actions ◦ ZAMCOM ◦ ORASECOM ◦ SADC ◦ Platform between China and neighbouring countries ◦ Tarim River: Desertification of river system due to overuse (similar to Chad) Hydropower in Kirgistan Irrigation in China ◦ Sharing hydrological data between China and Kazakhstan
  5. 5. Research Disaster risk reduction (flood and drought) Navigation (Not this group) Environmental management Fisheries (Zambesi) Water supply (Not this group) Mining and environmental impacts Tourism and ecosystems Operationalization ZAMCOM (Not this group) Monitoring and planning Irrigation and food security
  6. 6. Research priorities Research or development? Research in view of development (longer term): impact research 1) Irrigation and food security ◦ NPS pollution (surface and groundwater) ◦ Salinity 2) Quantification of ecosystem services ◦ Flood control (disaster response) ◦ Water supply sustainability ◦ Water purification (wetlands and indigenous forests) ◦ Food provision (e.g. fisheries) ◦ Surface-groundwater interactions, environmental flow, baseflow
  7. 7. Research priorities 3) Conservation, restoration and management of ecological infrastructure ◦ Paddy fields ◦ Wetland and dumbos ◦ Riparian strips ◦ Biodiversity, including control of alien species 3) EIA of dams ◦ Water ◦ Erosion ◦ Biodiversity ◦ Catchment conservation (population, human impacts, siltation)
  8. 8. Contributors Potential for special issue of papers on SA-China experiences in trans-boundary water management All participants of workshop
  9. 9. Partners for collaborations Thsingua University IWMI Hohai University Yunnan University CSIR GRIWAC ORASECOM ZAMCOM SADC
