The Low-cost sensor (LCS) technology to measure air quality has remarkably advanced in recent years and is now widely used by many organizations and companies and provides information on the atmospheric environment to citizens through data communication networks. Noticing the cost-effectiveness of LCS, development 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.
The Asian Development Bank (ADB) and the Network Center for the EANET (Asia Center for Air Pollution Research, ACAP) are jointly implementing 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 low-cost sensors (LCS) and existing reference level monitoring equipment are used in an integrated manner in pilot monitoring on Viet Nam and Myanmar.
As the effective use of reliable LCS and HAQMN is one of the EANET’s interests in capacity development, this activity is implemented as an EANET project, funded by the Ministry of the Environment, Japan (MOEJ) through the EANET Project Fund and co-financed in collaboration with the technical assistance project from ADB.
In 2019, the United Nations General Assembly adopted the Resolution at its 74th session to hold an International Day of Clean Air for blue skies on 7 September to urge the need to raise public awareness and promote and facilitate actions to improve air quality. The Training will also highlight the commemoration of this important day.
The EANET Training on Air Quality Monitoring Systems Using Low-Cost Sensors will take place on Wednesday 6 and Thursday 7 September 2023, from 13:30 to 17:00 (UTC+7), in Hanoi, Viet Nam, and online. The event will be jointly organized by the ADB, ACAP, and the Vietnam Institute of Meteorology, Hydrology, and Climate Change (IMHEN).

Discussions highlighted the potential and limitations of Low-cost sensor (LCS) technology. LCS is a portable and relatively cheaper monitoring system used for air quality monitoring, but challenges remain regarding data accuracy, calibration, and maintenance. LCS data can be valuable for non-regulatory monitoring applications and are powerful awareness-raising tools for citizen science. Efforts are being made to integrate LCS with reference-level sensors through projects like the EANET’s Hybrid Air Quality Monitoring Network (HAQMN) in Asia, in Viet Nam specifically, and guidelines are being developed to replicate this integration in other countries. LCS deployments have been conducted in the Philippines to fill coverage gaps, requiring local calibration and integration with conventional sensors. LCS are seen as complementary to traditional sensors, providing better coverage and valuable data for policymakers. Standardization, calibration, and integration need further attention to ensure the reliability of LCS for various purposes.

Air Quality Management Collaborative Efforts and Awareness Initiatives in Lao PDR
The objective of the panel discussion on Strengthening Acid Deposition and Air Quality Management in Lao PDR was to offer a forum to share information on air quality management and haze pollution. Representatives from government agencies NGOs, and other development institutions participated actively in the panel discussion and shared their thoughts on the air pollution issues in the country.
The alarming increase in the heat index in Lao PDR and in the region in April 2023, combined with wildfires and high air pollution, has led to a collective agreement to raise awareness about the detrimental effects of air pollution. The government of Laos is taking various measures to address air pollution and raise public awareness about its impacts, including conducting public awareness activities led by the Ministry of Public Health and the Ministry of Natural Resource and Environment and collaborating with relevant sectors to prevent air pollution from the agricultural sector. The National University of Laos (NUOL) has also introduced a supplementary curriculum on air pollution and air quality control.
The collaboration between the government and local communities was emphasized, involving engagement with local authorities and residents in educational programs. In the agricultural sector, the cassava farming practice is becoming a significant concern, leading to nutrient degradation in the soil and farmers resorting to clearing more land. Facing this issue, support is being provided to community-managed areas for sustainable crop preparation, discouraging the shifting of cultivation sites and promoting the use of plant residues to reduce burning.
Local government entities are also encouraged to collaborate with research institutes and other sectors to manage and prevent air pollution. The World Bank, in partnership with the NRERI, is developing an environmental and waste management project, aiming to enhance communication and access to educational resources through the development of online platforms including a mobile application, for public air quality monitoring.
The National Awareness Workshop participants highlighted the status of air quality monitoring stations, identified major sources of air pollution, and emphasized the importance of capacity building and international cooperation in addressing the transboundary haze issue. While efforts are made to improve the air quality assessment, these need to be further strengthened. Collaboration among various local and international stakeholders is key to addressing the air quality issue in Lao PDR.
