Progress of river health and e flow in china

  1. 1. Progress of River HealthAssessment and Environmental Flows Allocation in China Dr . Yu Xingjun  Ministry of Water Resources of China  February 2011 
  2. 2. Background Many rivers and lakes suffer quality deterioration,changes in morphology and hydrology, as well ashabitat degradation. Since 1990s, water reallocations have been carriedout in the Yellow River, Hei River and Tarim River, whichreduced deterioration of river health in those basins.
  3. 3. Background  In 1990s, a number of projects have been implemented whichhave improved river health, including:  “Water Supply to Zhalong Wetland”  “Water Diversion from the Yangtze River to the Taihu Lake”   “Water Supply to the Nansihu Lakes”  “Water Diversion from the Yellow River to the Baiyangdian Lake”  “Reservoirs Dispatching for Pollution Dilution in the Huai River ”  “Water Regulation to Control Sea Water Intrusion in the Estuary of the Pearl River”  Starting in 2004, pilot projects have been undertaken in 12cities to carry out ecological protection and rehabilitation of therivers and lakes in these regions.
  4. 4. National River Health Assessment Programme (NRHAP) Purpose: To help MWR and seven major river basin commissions perform their role in water and ecological protection and contribute to the achievement of river health objectives by 2020. Outputs: (i) river health assessment system established at national and major river basin levels; (ii) river health assessment bulletin issued to the public every 2 to 3 years .
  5. 5. Schedule of NRHAP Phase I Phase II Main tasks: Main tasks: •  Develop river health •  Revision of relevant assessment indicators, technical documents/ standards and guidelines methodologies •  Study on key •  River health survey for technologies a complete year • Capacity building •  Preparation of River Health Assessment •  River health Report (Pilots) assessment of major rivers/lakes •  Capacity building2009 2010 2011 2012 2013 2014 2015 2016
  6. 6. Workplan of Phase I Study on specific National KeyTechnical Preparation topics; Rivers and Lakes Technical Health Assessment Guidance; Report (2011) Pilot assessment.2009 2010 2011 2012
  7. 7. Current Work (2010 to 2011) One river, lake and reservoir selected forPilot Assessment each of seven major basins to carry out health assessment !  Ecological survey of typical rivers/lakes and characterisation study  Study on river health assessment in China and abroad  Data base analysis and investigation on monitoring capacity Research  River health assessment indicators Studies  River health assessment standards  River health assessment methodologies
  8. 8. Challenges for River Health Assessment   Insufficient knowledge about:  ecological zoning for river health assessment   threat-impact relations  indicators, standards and methodologies   Data base: Inadequate data and capacity on biological and habitats monitoring   Interagency collaboration: pollution (environmental protection), wetland (forestry), fishery (agriculture)   Lack of empirical studies: limited cases available in terms of number and types
  9. 9. Environmental Flows The 2002 Water Law requires that ecological waterdemand to be taken into consideration while developing andallocating water resources  One of the key principles guiding the preparation of thenational Integrated Water Resources Plan (IWRP) 2009 is tobalance the water demands for domestic, productive andecological use, and meet the basic water needs of rivers andlakes. IWRP 2009 proposes an objectives of national e-flows by2030 in terms of total volume
  10. 10. Challenges  associated  with  E-­‐flows •  Although objectives are set in IWRP 2009, e-flows have generally not been allocated to individual rivers/lakes •  E-flows analysis is qualitative and only a total (average annual) volume is prescribed – e-flows are not defined with reference to the required timing of the flow. •  Great difficulties exist while taking e-flows requirements into water resources administration, especially due to over-allocation and high demands for water
  11. 11. ACEDP    River  Health  and  Environmental  Flow  in  China  Project   (RHEFC)  River health assessment and environmental flow methodologies developed under RHEFC is of great help to China’s practice  RHEFC is highly relevant to China in the identification of suitable river health indicators and preparation of river health report cards   Field works, training and workshops have improved the capacity building of Chinese organisations involved. Impacts have been observed beyond the scope of RHEFC.
  12. 12. Next Steps for Bilateral Cooperation Extension proposal of RHEFC was approved by ACEFP on Feb. 22, 2011.   Extension will reinforce the approached already promoted during the current project  Extension will help MWR test national river health guidelines, including identification of indicators and formulation of standards
  13. 13. Next Steps for Bilateral Cooperation   Extension will provide advice and policy recommendations on e-flows, water allocation and basin planning methods based on international reviews.   Extension will further strengthen capacity building of Chinese sides through training, workshops, publication and dissemination.
  14. 14. Next Steps for Bilateral Cooperation  MWR and Queensland Department of Environment and ResourceManagement are preparing a MOU. International Economic andTechnical Cooperation and Exchange Centre and International WaterCentre will be responsible for implementation. The purpose of this MOU is: (i)  to continue previous collaborations (ii)  to facilitate the long-term sharing of knowledge and expertise in relation to the sustainable management of water resources (iii)  to collaborate across areas of education and training, applied research, and targeted project design and implementation  River health and e-flows are identified as two of the priority topics.
