The EANET Emission Inventory Webinar Workshop on Open Biomass Burning – Join us on December 5th!

Posted on by Aurélia Lemoine

 
1. Background

One of the key sources of particulate matter (PM) pollution in the EANET Participating Countries especially in Southeast Asia, is the open burning of biomass such as agricultural wastes, forests, and municipal wastes.

Open burning of agricultural crop residues is one of the key sources causing severe air pollution. Reducing emissions from agricultural waste burning is among the 25 recommended clean air measures in Air Pollution in the Asia Pacific: Science-Based Solutions (UNEP and CCAC, 2018).

It is essential to understand the current status of emissions from open biomass burning sources to consider effective mitigation ways. The emission inventory is a powerful tool for this purpose. However, methodologies to estimate emissions from open biomass burning are much different from those for other anthropogenic sources.

.

2. Objectives and Participants

The objectives of the Emission Inventory Webinar Workshop are to learn basic methodologies to estimate emissions from open biomass burning sources including considerable uncertainties. In addition, application methodologies of the emission inventories to analyze influences of open biomass burning emissions will also be introduced. Furthermore, participants will share short presentations about issues related to open biomass burning in their country, and discussions with experts will be conducted.

Target workshop participants are technical officers, practitioners, and policymakers who are involved in air quality management issues, especially in charge of or interested in developing a national emission inventory.

The EANET/IIASA International Workshop on Strengthening the Science-Policy Interface for Clean Air and a Sustainable Future in Asia – Join us on 19 December!

Posted on by Aurélia Lemoine

Registration is now closed.

.

1. Background

In many parts of Asia, the single greatest threat to human health and to a sustainable future is air pollution. A growing body of modeling research has employed emissions inventories, scenario development, and benefit estimation techniques to identify technological and behavioral changes that can limit that threat. The multiple benefits resulting from these interventions offer cost-effective solutions to air quality, public health, and other sustainable development concerns. One would therefore anticipate that the results that would translate easily into policy. However, this is not always the case. Frequently, there can be a disconnect between scientifically based models and the policies they seek to influence. It is therefore critical to discuss not only the most recent scientifically-based models but how that work can effectively interface with decision makers. In short, if models are going to matter, they need to be supported by efforts to strengthen the science-policy interface for clean air.

The EANET/IIASA International Workshop on Strengthening the Science-Policy Interface for Clean Air and a Sustainable Future in Asia will take place on Monday 19 December 2022, from 13:30-17:00 (Tokyo Time: UTC +9).

.

2. Objectives and Participants

The primary objective of this half-day workshop is to provide learning opportunities on the state-of-the-art modeling analysis that can strengthen that interface in Asia.

This workshop consists of three sessions as follows:

  • Session 1 – Multiple development benefits of coordinated actions to tackle air pollution: This session is jointly organized by the Acid Deposition Monitoring Network in East Asia (EANET) and the International Institute for Applied Systems Analysis (IIASA). The modeling analysis employed by a project activity of EANET is presented along with modeling analysis results from ongoing collaborative research projects between IIASA and the Ministry of the Environment of Japan (MOEJ) on multiple development benefits of coordinated actions to tackle air pollution.
  • Session 2 – Exploit synergetic linkages among SDGs: This session presents modeling analysis results from ongoing collaborative research projects between IIASA and MOEJ on synergies of achieving several sustainable development goals.
  • Session 3 – How to implement and promote a science-policy dialogue: This panel discussion session will discuss how we can design science-policy dialogue to reflect implications from modeling analysis to policy development and to co-design models by incorporating social and institutional dimensions of feasibility.

Expected targeted participants are policymakers, scientists, researchers, practitioners, and technical officers of local/national governments working on air pollution-related problems in the EANET Participating Countries of EANET and beyond.

EANET Workshop on the Relationship between the Atmospheric Environment, Human Health and Ecosystems – Join us on October 31st!

Posted on by Aurélia Lemoine

 

The registration is now closed.

1. Background

As mentioned in the Medium Term Plan for the Acid Deposition Monitoring Network in East Asia (EANET) (2021-2025), the Participating Countries established the EANET in 2000 to recognize increasing concerns about acid deposition due to rapid economic development in East Asia that had jeopardized environmental sustainability. The establishment of EANET has benefited from the viewpoint of environmental sustainability and the experience of Europe and other regions that have earlier carried out relevant activities for monitoring acid deposition and related substances, including quality assurance and quality control (QA/QC), data accumulation, and evaluation. Over the span of 20 years, the accumulation of scientific knowledge and regional economic development, the environmental pollution situation worldwide, and the urgent and important fields of action have changed significantly, and, in November 2021, the Twenty-third Session of the Intergovernmental Meeting on the Acid Deposition Monitoring Network in East Asia (IG23) for the EANET made important decisions on the expansion of the scope of the EANET, from acid deposition, to also include a wider scope of atmospheric environment-related substances.

As the deterioration of the atmospheric environment by pollutants emitted from anthropogenic activities may cause adverse effects on humans and ecosystems, the Workshop on the Relationship between the Atmospheric Environment and Human Health and Ecosystems will allow discussions and experience-sharing with various stakeholders, such as policymakers, scientists, and the general public.

To further discuss and understand scientific knowledge and relevant policy measures, the Workshop on the Relationship between the Atmospheric Environment and Human Health and Ecosystems will gather renowned East Asian and European researchers and experts from academia (Hokkaido University, Japan, and Nanjing University of Information Science and Technology, China), international organizations (CLRTAP-UNECE, WHO, IIASA), and from the Network Center for the EANET, to share scientific findings on the effects of atmospheric deposition on human health and ecosystems, as well as best science-based practices for policy-makers to reduce the impacts of atmospheric pollutants.

.

2. Objectives and Participants

The Workshop on the Relationship between the Atmospheric Environment and Human Health and Ecosystems will aim at:

  • sharing scientific knowledge on the relationships between the atmospheric environment and human health and between the atmospheric environment and ecosystems
  • showcasing science-based policy experiences on the reduction of atmospheric pollutants in other regions, such as Europe
  • contributing to sharing a common understanding of future directions for environmental measures to be developed by policymakers and scientists at the national and international levels

Although this event is open to the public, the expected participants will be mainly government officials from the EANET Participating Countries, scientists, such as the Scientific Advisory Committee members, Task Force members, other relevant scientists from the EANET and beyond, etc.

Workshop on National Air Quality Monitoring Systems and Methodologies with Related Partners – Join us on July 6th!

Posted on by Aurélia Lemoine

.

The registration is now closed.

.

1. Background

The EANET as an intergovernmental network in East Asia has achieved excellent progress in monitoring cooperation and had great progress in dealing with common concerned problems in the region. The EANET has been monitoring more than 18 atmospheric substances including ions at 64 monitoring sites in the EANET Participating Countries. EANET implements five monitoring items – wet deposition, dry deposition (air concentration), soil and vegetation, inland aquatic environment, and catchment-scale monitoring.

Depending on differentiated economic stages, industrial structures and meteorological conditions, Participating Countries face diversified environmental challenges and priorities, and even in the same region, the challenges differ from time to time. Therefore, in dealing with acid deposition and air pollution issues, it becomes critical to understand the latest atmospheric environment status in the EANET region firstly, and constantly keep up with the latest trend of air pollution measurements and state-of-the-art research methodology/technology, and fully utilize all aspects of resources to seek the solutions in improving air quality in EANET.

Through more than 20 years of activities, the EANET has established a comprehensive and integrated monitoring network, and EANET monitoring data has been used to evaluate and analyze the atmospheric environment in East Asia. The EANET has focused on the national level to promote cooperation among thirteen Participating Countries to address air pollution, including acid deposition issues, and has achieved significant progress in improving air quality in the East Asia region. However, considering the lifetime of air pollution substances, city-level air quality management is also important besides the national level. Furthermore, in terms of implementing management regulations and standards, along with initiatives from central governments, the local/city governments are also crucial in steadily carrying out various measurements.

To accelerate its further development, the Twenty-third Intergovernmental Meeting of the EANET reached an agreement to expand its scope and enable the EANET to conduct monitoring of more atmospheric environment-related substances. In response to this historical decision of scope expansion and steadily undertaking the necessary actions to adopt the changes of EANET, sharing the latest monitoring system and methodologies, discussing the most pressing challenges, and thinking together about possible solutions among the EANET Participating Countries with related partners are critical.

This workshop will gather different stakeholders (scientists and researchers, government officers, technicians including QA/QC managers, the representative of an international organization) together and invite them to discuss from different perspectives on how to overcome the challenges so as to improve the monitoring system in EANET.

This workshop will be divided into two sessions. The first session will briefly introduce the EANET monitoring activities and its function, followed by the case studies of Japan, R. of Korea, and China. In addition, the specific monitoring methodologies including QA/QC activities will be also introduced. In the second session, the panel discussion will take place involving different stakeholders to seek solutions for improving the EANET monitoring system.

.

2. Objectives and Participants

This workshop aims to provide an opportunity of sharing a wide range of national and international experiences in the field of atmospheric monitoring, discussing the current development and future challenge of monitoring systems and related methodologies in EANET.

EANET Seminar on Expanding Monitoring Systems using Low-Cost Sensor (LCS) – Join us on July 21st!

Posted on by Aurélia Lemoine

.

The registration is now closed.

.

1. Background

Low-cost Sensor (LCS) technology to measure air quality has expanded remarkably in recent years, and it is now widely used by the private sector. It provides information on the atmospheric environment to citizens through data communication networks.

Noticing the cost-effectiveness of LCS, international organizations have started to promote the use of LCS in selected areas to strengthen the capacity of governments where official air monitoring networks are insufficient. However, various surveys conducted by US-EPA, the EU, and others, as well as some experiences in the Asian region reveal that some types of LCSs in the market have problems with accuracy and reliability, while some types are reliable. It is observed that some less reliable LCS and improper use of LCS, including wrong interpretation of measured data, sometimes cause problems including unnecessary social confusion.

Air quality monitoring authorities, such as US-EPA, recommend that LCS is to be used for providing supplementary information for non-regulatory purposes. They recently developed testing protocols to evaluate the accuracy and reliability of LCS.

In most areas in the Asian region, air quality monitoring capacities of the national and local governments are still limited and need to be developed to improve their air quality to achieve SDGs. Considering emerging sub-regional-scale and serious seasonal air pollution events, such as PM2.5, building a network of reliable and internationally comparable air quality data becomes more important.

Thus, it is necessary for practitioners to consider how they can wisely select and use reliable LCS with the network of reference-level sensors in an integrated manner for enhanced air quality monitoring.

The EANET has been developing an air quality monitoring network in the East Asia region with governments and scientists from its 13 Participating Countries and assisting them to develop domestic capacity. The EANET is expanding its scope and seeking collaboration with potential partners. The EANET is conducting this activity considering the best use of reliable LCS for capacity building among its Participating Countries.

.

2. Objectives and Participants

The EANET will proceed with technical studies and capacity building on methods for collecting reliable air quality data with a concept of Hybrid Air Quality Monitoring Network (HAQMN) where highly reliable LCS and existing reference-level monitoring equipment are used in an integrated manner.

This concept and relevant work provide opportunities for EANET: (1) to strengthen its monitoring network, especially in expanding spatial coverage of the motoring of PM2.5 and ozone with high time resolution; and (2) to assist the Participating Countries of the EANET in developing their air quality monitoring network.

With such overarching goals, the objectives of this Seminar are to provide venues for stakeholders in the EANET Participating Countries and other areas to learn the above-mentioned background, issues, and opportunities of LCS in detail from the experiences of the air pollution monitoring experts.

Although this event is open to the public, the expected participants will be mainly representatives, experts, and practitioners of air quality monitoring from the EANET Participating Countries, non-Participating Countries, academia, and monitoring related service providers.
