Background
Many rivers and lakes suffer quality deterioration, changes in morphology and hydrology, as well as habitat degradation.
Since 1990s, water reallocations have been carried out in the Yellow River, Hei River and Tarim River, which reduced deterioration of river health in those basins.
Background In 1990s, a number of projects have been implemented which have 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 12 cities to carry out ecological protection and rehabilitation of the rivers and lakes in these regions.
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 .
Schedule of NRHAP
2010 2011 2012 2013 2014 2015 2016 2009
Phase I Main tasks:
• Develop river health assessment indicators, standards and methodologies
• River health survey for a complete year
• Preparation of River Health Assessment Report (Pilots)
• Capacity building
Phase II Main tasks:
• Revision of relevant technical documents/guidelines
• Study on key technologies
• Capacity building
• River health assessment of major rivers/lakes
Workplan of Phase I
Study on specific topics;
Technical Guidance;
Pilot assessment.
Technical Preparation National Key
Rivers and Lakes Health Assessment
Report (2011)
2009 2010 2011 2012
Current Work (2010 to 2011)
Pilot Assessment One river, lake and reservoir selected for each of seven major basins to carry out health assessment !
Research Studies
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
River health assessment indicators
River health assessment standards
River health assessment methodologies
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
Environmental Flows The 2002 Water Law requires that ecological water demand to be taken into consideration while developing and allocating water resources
One of the key principles guiding the preparation of the national Integrated Water Resources Plan (IWRP) 2009 is to balance the water demands for domestic, productive and ecological use, and meet the basic water needs of rivers and lakes.
IWRP 2009 proposes an objectives of national e-flows by 2030 in terms of total volume
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
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.
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
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.
MWR and Queensland Department of Environment and Resource Management are preparing a MOU. International Economic and Technical Cooperation and Exchange Centre and International Water Centre 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.
Next Steps for Bilateral Cooperation
