Acting Post-Disaster

Comunal, Ewésh Yawalapiti Waurá and Luis Octavio de Faria e Silva

The Envolvimentos (Involvements) fostered an open dialogue with social movements and diverse territories, converging on the exhibition of the 14th São Paulo International Architecture Biennial, which runs from September 18 to October 19 at OCA in Ibirapuera Park. Architects and leaders from villages, terreiros, riverside communities, and peripheral neighborhoods jointly explored architectures for inhabiting a heated world in debates that deepened the exhibition's central ideas.

Participants involved in projects across diverse territories and contexts addressing issues such as coexistence with water and floods, heritage preservation, forest protection and sustainable management, urban agriculture, mechanisms for enabling low-impact lifestyles, and the recognition of nature as a subject of rights were invited to participate in the dialogue. These are ways of inhabiting, building, perceiving, participating in, and transforming the territory.

4th Involvement – Acting post-disaster

The fourth gathering examines the preservation of memory and cultural heritage in post-disaster contexts, while honoring spiritual dimensions of recovery. It critically reflects on how human interventions both generate catastrophes and intensify systemic inequalities.

Guests:

Comunal
Cidade do México, Mexico

Founded by Mariana Ordóñez Grajales and Jesica Amescua Carrera, Comunal envisions architecture as a collaborative social process – living, open, and constantly evolving – with residents at the heart of decision-making. In communities affected by earthquakes, hurricanes, and floods, the studio has facilitated and guided social reconstruction processes, rebuilding not only homes but also local productive systems and community ties.

Ewesh Yawalapiti Waura
Associação Terra Indígena Xingu
Território Indígena do Xingu, MT, Brazil

Lawyer graduated from UFMT (Federal University of Mato Grosso) and Executive Director of the Associação Terra Indígena Xingu (ATIX). ATIX works to defend indigenous rights, protect territories, and promote the traditional cultures of the Xingu region. Ewésh, alongside the Waujá people, has been actively involved in protecting Kamukuwaká Cave—a sacred site for the Upper Xingu peoples and a heritage site recognized by Iphan (Institute of National Historical and Artistic Heritage). The cave suffered vandalism, and a replica was later installed within the Ulupuwene Village.

NOTE OF CONDOLENCE

With deep sorrow, the Brazilian Institute of Architects – São Paulo Department (IABsp) mourns the passing of architect and landscape architect Kongjian Yu, a global leader in ecological urbanism, and the members of his team who accompanied him, tragically killed during the filming of a documentary. The institute is honored to have had him as a participant in the 14th São Paulo International Architecture Biennial, where his transformative vision strengthened the dialogue between global challenges and local realities. IABsp emphasizes that Yu's contribution, which transcends borders, will remain an inspiration for generations and expresses its condolences to China, to the families of all the deceased, to his friends, and to all those impacted by his genius and dedication.
