Judicial Decision Could Transfer 20 Sq Km From Aracaju to São Cristóvão, Affecting Tourist Neighborhoods, 30 Thousand Residents and Investments Already Made by the Capital

Next year, around 30 thousand people currently living in Aracaju may become citizens of São Cristóvão. This is happening because a judicial decision requires the Sergipe capital to return an area of 20.78 sq km to the neighboring municipality.

The state government has already confirmed it will coordinate a technical study to update the cartographic boundaries. The measure was defined after a conciliation hearing between the Federal Court and the municipalities.

Technical Study and Forecasted Steps

The forecast is that the study will begin next month and end by April 2026. Cartographic analyses, public hearings, and area surveys are planned. At the end, a new boundary proposal will be delivered.

Determination of the Court

The court has determined that the state government and the IBGE act on territorial review. It was emphasized that the law used as a basis, from 1954, contains diffuse and imaginary landmarks, which makes it difficult to identify the boundaries.

“The entire procedure will strictly follow the final court decision,” said the government. “The process will be gradual, with phases of study and dialogue with the population. The final decision does not rest with the state executive, but with the Federal Court.”

Affected Neighborhoods

If the change is confirmed, neighborhoods in the Expansion Zone such as Santa Maria, Mosqueiro, Robalo, Areia Branca, and Matapuã will pass to São Cristóvão. Mosqueiro is known for its warm water beaches and luxury condominiums.

As a result, São Cristóvão’s population will increase from 95 thousand to 125 thousand residents. Aracaju, on the other hand, will drop from 603 thousand to 573 thousand inhabitants.

The transfer involves 6,700 properties, 14 schools, three health posts, and 31 km of paved streets. It also includes water and electricity networks, squares, and green areas. The property tax alone in the area represents R$ 5.2 million per year.

Action to Reverse Decision

The Prosecutor’s Office of Aracaju has filed a Rescission Action in TRF-5. The aim is to secure the Expansion Zone as part of the capital’s territory. The claim is that more than 70 years of municipal administration were disregarded.

According to the Attorney General Hunaldo Mota, the action relies on the Law of Introduction to the Brazilian Norms, which requires evaluating practical consequences. “We seek for the Court to consider the real situation of the region and the sense of belonging of the population,” he stated.

According to Mota, this is not just a constitutional matter. It is necessary to assess the social, economic, and structural impacts that were ignored in previous processes.

In education, 14 municipal schools serve 6,405 students, with a monthly cost of R$ 3.3 million. In health, three units assist 32,837 people, with a monthly investment of R$ 674 thousand.

Additionally, works from the Aracaju City of the Future program allocate R$ 165 million for macro-drainage and urbanization in Mosqueiro and Areia Branca. Part of the funding comes from an US$ 84 million loan from the New Development Bank.

São Cristóvão’s annual budget is R$ 352 million. For the PGM, this amount is insufficient to maintain services that currently cost R$ 10.7 million per month. “It is essential to assess whether the neighboring municipality would be able to take over schools, health posts, and ongoing works,” Mota emphasized.

Historical Recognition of the Territory

The PGM also emphasizes that previous decisions have already recognized Aracaju as responsible for managing the area.

The capital’s administration implemented urban infrastructure, regularized land plots, and monitored the environment.

Another point is the road access, provided solely by Aracaju. According to the Prosecutor’s Office, residents identify themselves as part of the capital, reinforcing the historical and cultural bond.

Position of São Cristóvão

Mayor Júlio Nascimento states that the city is prepared. “The dispute is not about narratives, it is about justice and historical truth. São Cristóvão has always owned this territory.”

He recalls that the municipality was the first capital of Sergipe. For him, it is “a fallacy” to say that there are no conditions to take over the region. “The truth is that these areas have always belonged to São Cristóvão, and this has been definitively recognized by the Court.”

Action of the Government and IBGE

The state government reaffirms that it operates in cooperation with the judiciary, ensuring technical and legal security in the process.

IBGE stated that it only follows divisions defined by the Public Authority. Any changes will only occur after officialization of the redefinitions.

Territorial Dispute: Historical Context

São Cristóvão is known for its historical heritage, such as Praça São Francisco, listed by Iphan and declared a World Heritage Site by UNESCO.

In 1820, with Sergipe’s emancipation from Bahia, São Cristóvão became the capital. In 1855, the seat was transferred to Aracaju to serve the sugar mills that needed a port for their production.

In 1954, in the face of an energy crisis, the city allegedly ceded coastal area for the installation of an electric generator in the capital.

Today, Jardim Rosa Elze concentrates the largest population in the municipality, with 55 thousand residents. Its proximity of 10 km to downtown Aracaju strengthens the links.

The neighborhood grew after the establishment of the Federal University of Sergipe, which boosted development.

Territorial Dispute: Historical Context

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.

Norway is drilling 27 kilometers of rock 392 meters below the bottom of a fjord to build the world’s largest and deepest underwater road tunnel — when completed, a 21-hour journey will be reduced to 10.
