Historical Decisions on the Expansion of the Scope of the EANET

Following the decision of the Twenty-second  Session of the Intergovernmental Meeting (IG22), held in November 2020, the EANET Participating Countries’ representatives have been working relentlessly on the process to expand the scope of the EANET, from acid deposition to also include a wider scope of atmospheric environment-related substances.

This historical progress required the EANET to develop a text supplementary document to the EANET Instrument, to define the scope of expansion and the target substances to be included in the EANET activities. In a landmark decision, 20 years after the creation of the Network, the IG23 has adopted the text of the Supplementary Document (Annex) to the Instrument for Strengthening the Acid Deposition Monitoring Network in East Asia.

The EANET Project Fund and Project Guideline, a new financial mechanism allowing EANET to build co-financed projects with partners in the region and beyond, has also been approved by the IG23.

.

Ways Forward

In addition to these major decisions, the IG23 has also approved several important documents, including the Work Program and Budget of the EANET in 2022, and the Summary of the Twentieth Anniversary of the EANET publication, a new outreach document detailing the EANET’s past achievements and future opportunities.

As an important way forward for 2022, the EANET Participating Countries and partner organizations will be invited to start preparing and submitting project proposals for the pilot implementation of new EANET projects, in line with the EANET Project Guideline.

Updated EANET Monitoring Site Information Accessible Online

29 July 2021 – Niigata, Japan

To provide useful inputs for decision-making at the local, national, and regional levels, the Acid Deposition Monitoring Network in East Asia (EANET) has been monitoring acid deposition in East Asia for over 20 years. Recently, an updated version of the Site Information page has been released, displaying detailed information on each monitoring site.

.

Monitoring Acid Deposition across East Asia

With a coverage expanded through Cambodia, China, Indonesia, Japan, Lao PDR, Malaysia, Mongolia, Myanmar, Republic of Korea, Russia, Thailand, Philippines, and Viet Nam, EANET has assisted over the years in the deployment of monitoring stations in very diverse urban, rural and remote locations.

These monitoring sites gather high-quality data related to the deposition of major acidifying species and related chemical substances such as SO42-, NO3, H+ in precipitation, SO2, NO2 ozone, and particulate matter (PM) in ambient air.

.

.

Dry and Wet Deposition Monitoring

Among the EANET’s major activities, acid deposition monitoring consists mainly in the review and revision or establishment of national monitoring plans, as well as the deployment of monitoring equipment, using common methodologies, to measure wet deposition, dry deposition, analyze the impacts of these depositions on soil and vegetation as well as on the inland aquatic environment.

.

Comprehensive Monitoring Site Information Available Online

Recently updated in June 2021, the Site Information webpage displays detailed information about the current 66 EANET monitoring sites, including, among others, each site’s address and location, characteristics, the monitoring period and items, and monitoring instrument name.

To find out more about the results and data on each site, visitors can also access the sites’ data reports on the Monitoring System Data Report page.

Screenshots from some participants and Network Center and Secretariat Team members, discussing the various Working Group Session 2 Meeting agenda items

In these Recommendations, it is suggested to adopt the final draft of Medium Term Plan (MTP) (2021-2025) as well as the final draft of Work Programme and Budget in 2021 (WP&B 2021) that will be prepared according to the discussion at the Working Group Meeting sessions and relevant follow-up discussions.

In addition, the Working Group recommended the IG22 to recognize that “some activities relating to air pollution are a major interest to Participating Countries but may be beyond the current scope of the EANET. This includes types of activities and/or substances or targets areas that are related to air pollution beyond acid deposition” and to “ Express support for the need to expand the scope of the Instrument.”

EANET National Focal Points will meet again at the IG22, from 25 to 26 November 2020 through an online platform and discuss the finalization of the MTP (2021-2025) and Work Programme and Budget for the EANET in 2021 by considering the Recommendations of the WG Meeting.
