It was attended by 62 experts from 10 countries (China, Indonesia, Japan, Korea, Malaysia, Mongolia, Philippines, Russia, Thailand and Vietnam), five experts from five organizations (United Nations Environment Programme – International Environmental Technology Centre (UNEP/IETC), the World Bank, Commonwealth Scientific and Industrial Research Organization (CSIRO) of Australia, Norwegian Institute for Air Research (NILU), and United States National Oceanic and Atmospheric Administration (NOAA).
  2. The Meeting was chaired by Mr. Saburo Kato (Japan), with Dr. Quan Hao (China) and Dr. RTM Sutamihardja (Indonesia) as vice-chairmen, with the exception of agenda item 6 “Discussion on technical manuals and a guideline for monitoring acid deposition” which was chaired by Prof. Hajime Akimoto (Japan), and vice-chaired by Dr. Greg Ayers (CSIRO).
  3. The objectives of the meeting were to consider and discuss the design of the Acid Deposition Monitoring Network in East Asia and how the proposed Network should be established, as well as to finalize three technical manuals and one guideline for monitoring acid deposition.
  4. At the beginning of the meeting, a discussion of national efforts made and ongoing progress towards the improvement and the expansion of the acid deposition monitoring in each country were reported by experts from China, Indonesia, Japan, Korea, Mongolia, Russia, Thailand and Vietnam. All of the reports expressed support for the initiative on Acid Deposition Monitoring Network.
  5. During the discussion on the proposed Network, many participants expressed their support for its establishment. At the same time, it was emphasized that a step-by-step approach is necessary for the realization of the Network.
  6. As a result of positive discussion, the meeting concluded the “Design of the Acid Deposition Monitoring Network in East Asia” (hereinafter referred to as “The Design”) as attached.
  7. In The Design, the following timetable toward the establishment of the Network was proposed.
    sp sp
    1997 establish a Working Group to prepare for the preparatory phase activities and the first inter-governmental meeting
    1998 convene the first inter-governmental meeting to review and finalize the design of the Network system
    1998 – 1999 preparatory phase activities of the Network
    2000 convene the second inter-governmental meeting to review the preparatory phase activities and to review and approve the design of the Network system
    begin full operation of the Network

Hara, Dr. T. Fukuyama, Dr. T. Totsuka and Dr. N. Ogura. After vigorous discussion, revisions were made and the following manuals and guideline were adopted.
    (i) Technical Manual for Wet Deposition Monitoring
    (ii) Guideline for Dry Deposition Monitoring
    (iii) Technical Manual for Monitoring Soil and Vegetation
    (iv) Technical Manual for Monitoring Inland Aquatic Environments

    During the discussion, it was recognized that, considering the nature of East Asian region and the status quo of the scientific research on the acid deposition monitoring, these manuals and guideline should be improved in some points, and that continued efforts should be made to improve manuals and guideline through updating on a regular basis.

  9. All participants were informed that the Environment Agency of Japan decided to set up the Network Center in Niigata city, 300 km north of Tokyo, and will begin preparatory work for its establishment. The Environment Agency of Japan proposed to host the working group meeting mentioned above. The participants gratefully accepted such report and proposal.
