Committee of Environmental Engineering

1. Outline of Committee of Environmental Engineering
The Committee of Environmental Engineering was established as the sanitary engineering committee in 1962, changed to its current name in 1994. Since its start, it has dealt with a wide range of regional and global environmental issues, mainly in water supply, sewerage and solid waste treatment. Through the annual environmental engineering research forum and other subcommittee activities, the committee takes a leadership in developing environmental engineering.

2. Environmental Engineering Research Forum
In the Environmental Engineering Research Forum, which is held in late November or in the beginning / middle of December every year, 100-120 latest research results are presented by civil-engineering related professionals from industry, government, and academia and discussed peer-reviewed papers, presentations on new technologies and projects, and papers under non-specified category. The peer-reviewed papers are published as Division G (environment) of JSCE Journal.

In addition to research presentations, the committee organize the sessions with timely topics, in which lectures and panel discussions are conducted by experts; those sessions take an important role as a forum for industry-government-academia exchange. Recent sessions organized have topics such as “Development of Cutting Edge Sewage Technology and Environmental Engineering Areas” (FY2018), “Development of Environmental Engineering in a Population Declining Society” (FY2017), “Current Status and Future Prospects of Industry-Government-Academia Collaboration in Environmental Engineering” / “Challenges and future prospects related to international development in the water and sewerage fields to achieve the SDGs” (FY2016).

3. Subcommittee Activities
Subcommittees have been established for the purpose of promoting deep discussions and researches on specific themes, and workshops, lectures, publication of reports, etc. are conducted at each subcommittee. Currently, the Research Subcommittee on Advanced Technology of Sewerage Promoting Collaboration in Other Fields, the Next Generation Sewerage Subcommittee, the Environmental Technology Philosophy Subcommittee, the Clinical Environmental Technology Subcommittee, and the Water Infrastructure Renewal Subcommittee are actively working.

4. Overseas Study Tour for Students to Consider Environmental Issues

The Environmental Engineering Committee organizes study tours for Japanese students to consider environmental issues abroad once a year, and reached its 20th milestone in FY2018.
In recent years, we have visited Uzbekistan, Thailand, China, Vietnam, etc. to observe the current state of local environmental problems and paid a visit to local universities and JICA offices for about a week. The tour’s aim is to promote international exchange and discussions on common and different environmental issues between the participants and their local counterparts. Furthermore, the language used in the tour is English: explanations at visiting places, lectures, group works, and discussions on research projects carried out in English. The tour in which many students and faculties from universities across the country participate is regarded as a good opportunity for them to make information exchange and to develop self-study in terms of education and research project. The committee has been able to organize the tour with great support from many stakeholders.

Activity Report of ACECC TC-16

The Asian Civil Engineering Coordinating Council (ACECC) TC-16 is a technical committee that focuses on the "Intelligent Transport System (ITS) Solutions for Urban Traffic Problems in the Asia-Pacific Region." The TC-16 organizes ITS solutions for common urban traffic problems among Asian countries, such as traffic congestion, accidents and environmental issues, which are a result of rapid urbanization associated with economic growth and increase in the number of vehicles. The TC-16 also has been discussing on the methods of ITS introduction which correspond well to the levels of economic development and land development of individual countries. In the fiscal year 2016, building on its achievements, the TC-16 published the “ITS Introduction Guide” (Photo1) on the websites of ACECC and the Japan Society of Civil Engineers (JSCE).
This publication is supported by International Scientific Exchange Fund(ISEF)of JSCE.

The ACECC TC-16 held a session inviting members of each country to CECAR8 (8th Civil Engineering Conference in the Asian Region) held in Tokyo on April 2019. In that session, some cases of ITS implementation in each country such as two MaaS (Mobility as a Service) projects launched in Taiwan, efforts to ITS technology in Japan, traffic information distribution to realize MaaS,  operation using probe data of ETC 2.0, and management and the examination situation regarding congestion control on expressways in Thailand, were reported.
In addition, for urban traffic problems, we organized solutions using cutting-edge ICT (Information and Communication Technology), and discussed how to introduce ITS according to the stages of economic development and land development in each country.

The ACECC TC-16 will continue the research on advanced efforts and use cases of the ITS, including MaaS, in various countries around the world, and update the “ITS Introduction Guide” in order to contribute to solving urban traffic problems in Asian countries.
