Sometimes, he works to bring peace between groups. For example, he helped restore peace with the Korubo Indians. Before this, there had been conflict with FUNAI officials.
Sydney started his career many years ago. He helped the Villas Boas brothers with their work. He worked near the Xingu River area. In the late 1980s, he helped the Arara people. This happened after conflict near the Trans-Amazonian Highway. The Arara people suffered from new diseases. This sad event changed how Sydney thought about helping tribes.

Sydney Possuelo is a prominent Brazilian explorer, ethnographer, and social activist. An ethnographer is a person who studies the cultures of different human groups. Possuelo is considered the leading authority on Brazil's remaining isolated Indigenous Peoples. These are groups living in the Amazon who have had little to no contact with modern society. His life's work focuses on protecting these tribes from outside threats. He works to ensure their survival and their right to live undisturbed. 
Possuelo began his professional journey assisting the Villas Boas brothers. They were well-known for their work among Indigenous groups near the Xingu River. In the late 1980s, he worked with the Arara (Para) people. This happened after conflict broke out between the Arara and crews building the Trans-Amazonian Highway. The contact led to a major demographic upset for the Arara. They fell victim to Eurasian diseases that their bodies were not prepared to fight. Even though the agency FUNAI had prepared for such events, the epidemic was still devastating. The Arara also faced socioeconomic marginalization after they were assimilated. This difficult experience changed Possuelo's view on how to handle uncontacted tribes.
Possuelo realized that the old policy of assimilation and acculturation was flawed. Acculturation is the process where one group adopts the traits of another. He believed that forcing tribes to join modern society caused great harm. To fix this, he worked with other FUNAI officials like Gilberto Pinto Figueiredo. Together, they successfully advocated for a new specialized department. This was the Department of Indigenous in Isolation, or Departamento de Indios Isolados. Possuelo became its very first Director in 1987. This department focused on protecting tribes by keeping them separate from outside influence.
Under Possuelo's leadership, the department achieved massive results for land protection. In just two years, the department doubled the surface size of officially designated Indigenous land in Brazil. He led many expeditions into the most isolated parts of the Amazon region. His goal was to learn about these tribes while shielding them from outsiders. One notable success was restoring peaceful relations with the Korubo Indians. This group was considered "uncontacted" and had previously killed some FUNAI officials. Among those lost was Raimundo (Sobral) Batista Magalhães, a close friend of Possuelo.
Possuelo's career also involved navigating difficult political waters within the government. On January 24, 2006, he was dismissed as the director of the Department of Unknown Tribes. This happened shortly after he criticized the director of FUNAI, Mercio Pereira Gomes. Possuelo had compared Gomes to ranchers, loggers, and land-grabbers. He felt the leadership was not prioritizing Indigenous land rights correctly. Despite this setback, he did not stop his activism. He continued his work through a non-governmental organization called the Instituto Indigenista Interamericano. He remains a vocal defender of Indigenous rights in Brazil.
In recent years, Possuelo has continued to monitor the safety of Indigenous lands. In a 2022 interview, he criticized the administration of President Jair Bolsonaro. He blamed the administration for an increase in illegal invasions of Indigenous territories. Possuelo stated that Indigenous people were facing their worst moment in Brazilian history. He accused the government of giving cover to criminals and trespassers. Regarding the 2022 general election, he discussed candidate Luiz Inácio Lula da Silva. While he had issues with certain aspects of Lula's past, he hoped for improved conditions for Indigenous Brazilians.
His dedication has earned him significant international recognition and awards. In 1998, he received the Bartolomeu de las Casas honor. He was also awarded a gold medal from the Royal Geographical Society. In 2001, the United Nations named him "Hero of the year." Time Kids Magazine also gave him the title "Hero of the Planet." His life is even documented in literature. He is the main subject of the 2011 book, "The Unconquered." This book by Scott Wallace describes a 76-day expedition from 2002. During that trip, Possuelo searched for the "Arrow People" in the Vale do Javari Indigenous Land.
