life without borders between Tabatinga, Leticia and Santa Rosa

In the Alto Solimões region, on the border between Brazil, Colombia and Peru, the urban landscape merges with the geography of the Amazon rivers. In this area, Tabatinga, in the Amazon, and Leticia, in Colombia, form a group known as twin cities, connected by streets, businesses and services that operate in an integrated manner. Nearby is the island of Santa Rosa, belonging to Peru, a strategic point on the river, although it is not permanently inhabited.

This meeting between three countries creates a scenario in which political borders and daily life go hand in hand. The movement of people, goods and ships is constant, favored by the proximity between the shores and the tradition of coexistence between Brazilian, Colombian and Peruvian communities. At the same time, the presence of different legislation and control systems makes the region an area of ​​attention for local and federal authorities.

Triple border Brazil, Colombia and Peru: what characterizes this region?

In Alto Solimões, this triple border is concretely expressed in the towns of Tabatinga, Leticia and the Santa Rosa area, connected by rivers and river routes. It is a territory where national sovereignty is well defined on maps, but where, on a daily basis, social interactions tend to be more fluid.

Tabatinga, on the Brazilian side, functions as a regional hub for commerce, public services and access to Brazilian health and education policies. Leticia, Colombia, is an important tourist center and gateway to the Colombian Amazon, with an airport and infrastructure designed to receive visitors. The Peruvian island of Santa Rosa, although not permanently inhabited, plays an important role as a crossing point for ships and a territorial reference for the Peruvian presence at this border post.

How do the twin towns of Tabatinga and Leticia work?

Calls twin cities Tabatinga and Leticia form a continuous urban core, in which the separation between Brazil and Colombia, in many sections, is by streets, discreet walls or border markers. This type of configuration promotes intense relationships between residents on both sides, whether shopping, working, studying or accessing services. Many families maintain ties in both countries, which creates a particular social dynamic.

In practice, daily life includes situations such as:

• Brazilians who live in Tabatinga and work in establishments in Leticia.
• Colombians who use health and commercial services on the Brazilian side.
• Daily circulation of small boats connecting the banks of the Amazon/Solimões river.

This coexistence requires local administrations to engage in frequent dialogue, particularly on topics such as transport, health surveillance, education and security. In periods of intensified flows, such as during regional festivals or commercial dates, cooperation tends to become even more visible.

What are the challenges and particularities of the triple border?

THE triple border Brazil, Colombia and Peru presents a combination of economic opportunities and logistical challenges. On the one hand, cross-border trade displaces popular markets, river transport companies and small businesses that meet the demands of residents of all three countries. On the other hand, the distance from major national centers makes access to specialized services difficult, particularly in the field of very complex health and land transport infrastructures.

Among the particularities often associated with the region are:

1. Cultural diversity: presence of indigenous communities, riverside communities and urban populations with varied languages ​​and customs.
2. A river economy: the movement of goods and people is mainly carried out by boats, speedboats and ferries.
3. Border inspection: joint or parallel action by the security forces of the three countries to control migration and fight against illicit activities.
4. International cooperation: projects in the fields of health, environment and education often rely on bilateral or trilateral agreements.

These elements reinforce the strategic character of Alto Solimões both for Brazil and for Colombia and Peru, particularly in themes related to the protection of the Amazon forest and the monitoring of river routes.

What is the role of Santa Rosa Island in this context?

The island of Santa Rosa, belonging to Peru, is located opposite Tabatinga and Leticia, on the river bed. Although it is not permanently inhabited, it functions as a territorial reference for the Peruvian presence on the borders. In certain periods, the island receives temporary structures to support navigation, inspection or specific commercial activities, always in accordance with Peruvian standards.

From a geographical point of view, the island helps to delimit the area in which the waters and shores form the Amazonian triple frontier. For those who observe the map, it reinforces the conception of a point where three national states touch, but share the same river environment, the same equatorial climate and many similar challenges to sustainable development.

Outlook for the Alto Solimões region

When considering the future of the region, the triple border Brazil, Colombia and Peru tends to remain an area of ​​interest for public policies and international cooperation. The strategic importance of the Amazon in global debates on climate, environmental conservation and traditional peoples places this part of Alto Solimões in the spotlight at national and multilateral forums.

Initiatives to improve river mobility, strengthen border health and support local communities tend to directly influence routine in Tabatinga, Leticia and the Santa Rosa region. In this scenario, interaction between the three countries remains a central element, with agreements and projects that seek to reconcile border security, regional development and preservation of natural resources.
