Highlighted projects include the Onnut Urban Forest project, which represents the transformation of a former waste-management site into a vital green space; the Big Trees Project, which advocates for the effective management of urban trees; and the Mahidol Flower Lab, which researches plant diversity that elevates conventional tree planting into comprehensive ecological studies aimed at identifying plant species best suited for urban ecosystems.
