Overall Objective

• To develop sustainable land and water management
  strategies using fallout radio-nuclides for
  reducing soil erosion and improving soil and
  water quality in the Asia and the Pacific region.
  

5
Specific Objectives

• Measure soil erosion and depositing by combined
  use of 137Cs, 210Pb and 7Be
• Establish soil redistribution-soil quality
  relationship under different land management
  practices
• Develop guidelines to assess soil quality based
  on radio-nuclides
• Apply management practices for effectively
  improving soil and water quality as well as
  increasing organic carbon storage in soil.

6
Expected Outcomes

• Standardized methodologies and guidelines on the
  use of fallout radionuclides for the assessment
  of the soil quality-soil erosion relationship
  under different land use and management systems
• Soil and water resource management practices
  developed and implemented through field
  demonstration activities and training of farmers.

7
Regional Group Events

• During 2005-2006, China successfully hosted
  the following RCA Meetings
• IAEA/RCA Regional Training Workshop on
  Sustainable Land Use and Management Strategies
  for Controlling Soil Erosion and Improving Soil
  and Water Quality, 9-20 May 2005, Beijing and
  Yanqing, China
• IAEA RCA Mid-term Project Review Meeting, 22-25
  January 2007, Beijing, China

IAEA RCA Mid-term Project Review Meeting

• Most countries are advancing with their research
  according to work plan.
• Built up the basic national capacities for
  implementation of FRN methods
• The research is carried at selected studied sites
• Most countries achieved good experience with the
  use of basic 137Cs-method.
• Several countries started to implement other
  radionuclides.
• China as coordinating country is contributing by
  methodological expertise to whole group.
• The FRN capacities built by CAAS is at very good
  technical level and the staff involved in FRN
  research is very experienced and it is able to
  provide expert services for other countries.

14
Major Achievements-I

• Most participating countries have established
  laboratory facilities to measure 137Cs
  activities land use and topography surveys
  field sampling and measurements of 137Cs soil
  quality parameters were conducted.
• The local and national governors and publics are
  realizing the role of information gained by using
  fallout radionuclide techniques in assessment of
  soil erosion through the lectures, national and
  local workshop and publications delivered by the
  counterparts from participating member state .

15
Major Achievements-II

• In 2006, CAAS participated in the
  "IAEA-CU-2006-02 Proficiency Test on the
  Determination of 137Cs and 210Pb in spiked soil"

• Organized and conducted by the IAEA's
  Laboratories.
• The analytical results from CAAS were completely
  satisfactory, as compared with the reference
  values from the IAEA.

16
Major Achievements-III

• Member states from China evidenced that
  137Cs, excess 210Pb and soil organic carbon (SOC)
  move on sloping land by the same physical
  mechanism during tillage operations.

17
Constraints for implementingRCA Project RAS 5043

• Technical problems from some countries are
  major constraints for successful implementation
  of the project. They are
• field sampling design, field sampling methods of
  210Pb and 7Be,
• precise analysis of 210Pbex at laboratory, and
• data interpretation of measured 210Pbex and 137Cs
  and their linkage with soil quality parameters.
  These constraints can be solved through the
  following actions (expert missions) during
  2007-2008.

18
Expert Missions requested for 2007-2008

• The following expert missions requested by
  the participating countries during Mid-Term
  Project Review Meeting
• Indonesia, Mongolia, Myanmar, and Thailand
  request the expert missions to help them to
  develop field sampling design and field sampling
  demonstrations of 137Cs, particularly 210Pb and
  7Be during March and May 2007, and data
  interpretation and assessment in 2008.
• Pakistan requests expert mission in sampling and
  measurements of excess Pb-210 through IAEA expert
  mission.
• Vietnam needs expert mission assistance in soil
  erosion mapping with GIS systems mission .
