We are pleased to announce the **GSAPP World Actioning Summits**. The **World Actioning Summits** are a planetary forum for collaboration among scholars, practitioners, and activists. At a moment when the world’s most urgent challenges are unmistakably transnational, this coalition mobilizes the School’s worldwide networks to collectively think, act, and intervene. This effort will launch with the **[Inaugural World Actioning Summit in Seoul] (https://www.arch.columbia.edu/events/4044-inaugural-gsapp-world-actioning-summit-in-seoul)** on **March 14, 2026**. **We invite you to attend the Inaugural Summit in person in Seoul.** *Capacity is limited. Please RSVP below.* The Summit will foreground an ecological paradigm for the built environment: one that understands architecture and urbanism not as bounded objects, but as active agents within complex climatic, territorial, societal, technological, and bodily systems. Across the day, speakers will engage this paradigm through research, practice, and activism, articulating new modes of action commensurate with the transscalarity and urgency of current challenges. Speakers include: **David Benjamin ’05 M.Arch** (GSAPP, the living), **Minsuk Cho ’92 M.Arch** (MASS Studies), **Rachaporn Choochuey ’98 MSAAD** ((all)zone), **Jong Ho Hong** (SNU), **Nahyun Hwang** (GSAPP, NHDM), **Dean Andrés Jaque** (GSAPP), **Lydia Kallipoliti** (GSAPP), **Mireia Luzzarága** (GSAPP, TAKK), **Bart-Jan Polman ’10 MSAAD** (GSAPP), **Philippe Rahm** (Philippe Rahm architectes), **Wang Shu** and **Lu Wenyu** (Amateur Architecture Studio), **Shirley Surya** (M+), **Marc Tsurumaki** (GSAPP, LTL Architects), **Mark Wasiuta** (GSAPP), **Weiping Wu** (GSAPP). **The Inaugural World Actioning Summit** Saturday, March 14th, 2026. 10:30 AM - 7:30 PM Location: Anderson C, 36 Seongsuil-ro 6-gil, Seongdong-gu, Seoul *In person* [RSVP](https://docs.google.com/forms/d/e/1FAIpQLSeOgbrteSxlFwrgL-tRCHiKEuTr6cs74WHPELVKRBzIVhdgWQ/viewform)
