We will delve into the delicate balance between conservation, regeneration, and human as well as economic development specific to each biome, featuring interdisciplinary discussions from diverse experts. **This is a two-day conference, for more information about Day 2,** [**click here**](https://www.drclas.harvard.edu/event/2026-lemann-dialogue-six-biomes-multiple-realities-day-2)**.** Panels will be held primarily in Portuguese with simultaneous interpretation to English. *This event is free and open to the public.* #### [**Register here to attend virtually.**](https://harvard.zoom.us/webinar/register/WN_5SMpFgmnSe6qRjBFjqSMXw) ##### **About the Lemann Dialogue** The Lemann Dialogue is an annual conference on Brazil collaboratively organized between Harvard, Columbia, Stanford, and the University of Illinois at Urbana-Champaign, each home to centers supported by Jorge Paulo Lemann and the Lemann Foundation. The specific conference themes vary each year, but generally focus on contemporary social, economic, and political challenges in Brazil. By centering our discussion on Brazil´s six biomes, we aim to expand awareness beyond the often-dominant focus on the Amazon, and encourage new, cross-disciplinary research collaborations and connections. ## 2026 Lemann Dialogue: Six Biomes, Multiple Realities, One Country | Day 1 Speakers ### Fabio Scarano Atlantic Forest Professor of Ecology, Federal University of Rio de Janeiro ![Fabio Scarano](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-01/Fabio%20Scarano.jpg?itok=8yrzR9e2) ### José Augusto Padua Atlantic Forest Professor of Brazilian Environmental History, Federal University of Rio de Janeiro ![Jose Augusto Padua](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-01/Jose%20Augusto%20Padua.jpg?h=0c85444a&itok=T-nlH9pN) ### Marcelo Medeiros Atlantic Forest Salata Climate Action Fellow, The Salata Institute for Climate Change and Sustainability ![Marcelo Medeiros](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-01/Marcelo%20Medeiros.jpg?h=a6eda5bf&itok=Sj4PMkqo) ### Renata Piazzon Atlantic Forest, Priorities for Brazil’s Biomes in the 2026 Elections CEO, Instituto Arapyaú ![Renata Piazzon ](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-01/Renata%20Piazzon%20foto.jpg?h=90b27d70&itok=qdPt-54k) ### Kenia Rios Caatinga History Professor, Federal University of Ceará ![Kenia Rios](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-01/Kenia%20Rios.jpg?h=1ec84a76&itok=mDo_X8Jb) ### Washington Franca-Rocha Caatinga Full Professor, State University of Feira de Santana (UEFS) ![Washington Franca Rocha](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-01/Washington%20Franca%20Rocha.jpg?h=317b5175&itok=LbZpMj0M) ### Marcelo Leite Caatinga Journalist, Folha de São Paulo, Nieman Fellow at Harvard University (1998) and Knight-Wallace Fellow at the University of Michigan (2012) ![Marcelo Leite](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-01/Marcelo%20Leite.jpeg?h=68b0e3d3&itok=zmoubFIn) ### Daniela Nogueira Caatinga, Priorities for Brazil’s Biomes in the 2026 Elections Full Researcher and Lecturer, Universidade de Brasília (UnB) ![Daniela Nogueira](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-02/Daniela%20Nogueira.jpeg?itok=4Ru1uqnM) ### Marcelo Spinelli Elvira Priorities for Brazil’s Biomes in the 2026 Elections Executive Secretary, Observatório do Código Florestal ![Marcelo Elvira](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-03/Marcelo%20Elvira.jpeg?itok=xNCKJFcT) ### Gilson Barros Priorities for Brazil’s Biomes in the 2026 Elections Agronomist ![Gilson Barros](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-01/Gilson%20Barros.jpeg?h=59b8b3c6&itok=rF-ulHec) ### Mercedes Bustamante Priorities for Brazil’s Biomes in the 2026 Elections Full Professor, University of Brasília ![Mercedes Bustamante](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-01/Mercedes%20Bustamante.jpeg?h=0d1a429e&itok=R8a82HYh) ### Vanda Witoto Priorities for Brazil’s Biomes in the 2026 Elections Executive Director, Instituto Witoto ![Vanda Witoto - Jardiel Carvalho _Folhapress](/sites/g/files/omnuum12451/files/styles/hwp_16_9__480x270/public/2026-01/Vanda%20Witoto%20-%20Jardiel%20Carvalho%20_Folhapress.jpg?h=92d04f45&itok=Py6vat_6) arrow\_back arrow\_forward ## Panel Series Day 1 Agenda [ Register Here arrow\_circle\_right ](https://harvard.az1.qualtrics.com/jfe/form/SV_3wNc9BpNqvTIuF0) [ See Day 2 Agenda arrow\_circle\_right ](https://www.drclas.harvard.edu/event/2026-lemann-dialogue-six-biomes-multiple-realities-day-2) Open all sections Close all sections ### 1:00 - 1:30 PM | Opening Remarks expand\_more **Marcia Castro**, Andelot Professor of Demography; Chair, Global Health and Population, Harvard T.H.

It is the third most deforested and degraded biome, after the Atlantic Forest and the Cerrado, and covers most of the Northeast region—the poorest in the country. In the past, the region suffered severe famine outbreaks as a result of droughts, which persist and tend to worsen under the effects of climate change, although with less severe impacts on vulnerable populations today. The dialogue will cover the physical, ecological, historical, and public health factors that led to this current state, with an emphasis on adaptation, resilience, and water and food security.

It reveals threats that suffocate the way of life for those who live and resist in this unique biome. This short documentary places the Native Vegetation Protection Law at the center of the debate, showing how pressure on natural resources and changes in the landscape leave scars on biodiversity and on people. It also highlights the strength of the pampiano and the biome’s potential to unite high-value-added rural production with conservation. This documentary is the result of the Pampa Expedition, carried out by the Forest Code Observatory in October 2025. ### 5:15 - 5:30 PM | Coffee Break expand\_more ### 5:30 - 6:45 PM | Priorities for Brazil’s Biomes in the 2026 Elections expand\_more As Brazil prepares for the 2026 elections, we have tasked experts from each of the event’s biome-specific sessions with a single challenge: propose three concrete priorities per biome for the next administration.
