Led by Department of Industrial Design visiting professor Bart van Bueren, a team of National Cheng Kung University (NCKU) students in October traveled to Mactan in the central Philippine province of Cebu to construct four floating gardens alongside students from other nations.
The participating universities included Rotterdam University of Applied Sciences (RUAS) and Hanze University of Applied Sciences (HUAS) in the Netherlands, and the University of San Carlos (USC) in the Philippines, NCKU said.

They provide all kinds of mangroves and other plants a space to grow, she said, adding that the students had constructed the gardens completely from organic or reusable materials.
The gardens could improve local water quality and even reduce wind-induced waves or modify lowland flooding, Wang added.
The floating gardens can assist in protecting the coastline, increase habitat diversity and beautify the landscape, Wang said, adding that the project has received great reviews from the local government.

The professors and students presented their results at this year’s City Climate Scan Challenge at Cebu City in October.
The four floating gardens built by the students are about 6m2, totaling 25m2, Wang said.
Van Bueren explained the method for creating a floating mangrove garden, and then RUAS’ Tijmen Oudendammer led the team in measuring the clogged plastic pollutants on the riverside, NCKU said.
Using a mobile app, Floris Boogaard measured the water quality and taught the students how to map the floating gardens, NCKU added.
Last year, Wang and Van Bueren led students in constructing floating gardens on Tainan’s Anping Canal (安平運河).
Considering that most countries issue more than five denominations of banknotes, the central bank has decided to redesign all five denominations, the bank said as it prepares for the first major overhaul of the banknotes in more than 24 years.

The Centers for Disease Control (CDC) yesterday reported the first case of a new COVID-19 subvariant — BA.3.2 — in a 10-year-old Singaporean girl who had a fever upon arrival in Taiwan and tested positive for the disease. The girl left Taiwan on March 20 and the case did not have a direct impact on the local community, it said. The WHO added the BA.3.2 strain to its list of Variants Under Monitoring in December last year, but this was the first imported case of the COVID-19 variant in Taiwan, CDC Deputy Director-General Lin Ming-cheng (林明誠) said. The girl arrived in Taiwan on
South Korea is planning to revise its controversial electronic arrival card, a step Taiwanese officials said prompted them to hold off on planned retaliatory measures, a South Korean media report said yesterday. A Yonhap News Agency report said that the South Korean Ministry of Foreign Affairs is planning to remove the “previous departure place” and “next destination” fields from its e-arrival card system. The plan, reached after interagency consultations, is under review and aims to simplify entry procedures and align the electronic form with the paper version, a South Korean ministry official said. The fields — which appeared only on the electronic form
The Ministry of Foreign Affairs (MOFA) is suspending retaliation measures against South Korea that were set to take effect tomorrow, after Seoul said it is updating its e-arrival system, MOFA said today. The measures were to be a new round of retaliation after Taiwan on March 1 changed South Korea's designation on government-issued alien resident certificates held by South Korean nationals to "South Korea” from the "Republic of Korea," the country’s official name. The move came after months of protests to Seoul over its listing of Taiwan as "China (Taiwan)" in dropdown menus on its new online immigration entry system. MOFA last week
