The biennial Cornelia Hahn Oberlander International Landscape Architecture Prize was established to increase the visibility, understanding, appreciation, and dialogue around landscape architecture. The creation of the Oberlander Prize began in 2014, and the most recent laureate was landscape architect Kongjian Yu, the pioneer of the "Sponge City" concept. This year, The Cultural Landscape Foundation (TCLF) announced that Mexico City-based landscape architect Mario Schjetnan and his firm Grupo de Diseño Urbano (GDU) are the recipients of the 2025 Oberlander Prize. According to TCLF, Schjetnan belongs to a generation of landscape architects, architects, and urbanists who became aware of the environmental impacts of urban development and their consequences for life, the planet, and its inhabitants. He and the GDU team are the first Latin Americans to be awarded the Oberlander Prize laureate.

Beijing-based landscape architect Kongjian Yu has been announced by the Cultural Landscape Foundation as the recipient of the 2023 Cornelia Hahn Oberlander International Landscape Architecture Prize (“Oberlander Prize”). Kongjian Yu has gained international recognition for his concept of “sponge cities,” a measure to address and prevent urban flooding in the context of accelerated climate change. The concept was adopted as a national policy in China in 2013, prioritizing large-scale nature-based infrastructures such as wetlands, greenways, parks, canopy tree and woodland protection, rain gardens, green roofs, permeable pavements, and bioswales. Yu has been selected by the international jury of the Oberlander Prize, recognizing him as “a force for progressive change in landscape architecture around the world.” Organized biannually, the prize aims to recognize and give visibility to landscape architecture and the ways in which it can address issues of climate change and sustainability.
