Brazilian Navy conquers the “Blue Amazon”.

The Brazilian Navy has expanded its presence in the so-called “Blue Amazon,” an enormous Economically Exclusive Maritime Zone in the Atlantic Ocean. Today it is found closer to the mainland as a result of advanced telecommunications technologies.
After two months of intense technical work, Comsat has completed the installation of a telecommunications system that will link the Navy’s base on Trindade Island in the Atlantic, located 1,200 kilometers off the coast of Espirito Santo, to its bases on the mainland.

Now scientists and military personnel working on the island will have broadband Internet access via satellite and will be connected to the public telephony network in the rest of the country. It will now allow them to keep in contact with other Navy bases, their families, other research centers in Brazil, and the world at large. This new system replaces former solutions that were expensive and unreliable; based on high frequency radio and narrow band satellite systems.

The scientists often away from their families and the rest of society for months on end will now be able to stay in touch, through videoconferences with webcams.

The project included the installation of a satellite dish 3.6 meters in diameter, which provided Comsat with valuable experience that can be used in similar endeavors in the future. The Brazilian Navy wants to set up a similar system for the Scientific Station in the São Pedro and São Paulo Archipelago. These ten rocky islands, located 700 kilometers from the Fernando de Noronha Archipelago, are of strategic importance in controlling the country’s territorial waters and guaranteeing sovereignty over its Exclusive Economic Zone.

For Brazilian Naval Commander Costa Braga, these new telecommunications resources are important for scientific development and for integrating the rest of the country with the “Blue Amazon,” a rich and strategic geographic area, hitherto unknown to the majority of Brazilians.

Brazilian Bleu Amazon

The armed forces sectors are showing some preoccupation with the country’s maritime vulnerability, as one report in the Globo newspaper said. One of the reasons for this worry is the fact that the subsalt oil reserves are found in what is called the Exclusive Economic Zone (EEZ). This is Brazilian sea territory where the country has full sovereignty, and it extends 12 miles from the coast. In addition to this, the United Nations Convention on the Law of the Sea, which establishes a country’s economic rights out to 200 nautical miles from the coast for maritime resources in the soil, subsoil, and water, was signed in 1982. It is an EEZ however, in which ships with other flags can freely navigate and other countries can lay underwater ducts and cables. The problem is that 40 countries, among them, the United States, did not sign the convention.

Further, a small part of the subsalt is on the Brazilian continental shelf but in international waters, beyond the EEZ, thus allowing any other country to explore it. To guarantee sovereignty for the purpose of managing natural resources in the area, in 2004, the Brazilian government submitted a proposal to the United Nations Organization asking for rights on 960,000 square meters of the continental shelf – which would be a natural continuation of Brazilian territory. It is the so-called Blue Amazon which would cover 1,500,000 square kilometers in addition to the 3,500,000 square kilometers established by the EEZ, totaling 5 million square kilometers of maritime area. It is an enormous area with immeasurable natural resources. The UNO has not given a final opinion.

While waiting for a definition, the Brazilian navy has started to move. Recently, it has submitted a monitoring project called the Blue Amazon Managing System, still in study phase. The military is worried that Brazil does not have the structure and conditions to resist if any large power decides to explore the subsalt on the continental shelf – or even in the EEZ.

The Concepts of Water Footprint and Virtual Water

A water footprint is quite simply the volume of water used. At the individual level, this is expressed in litres. But at the national level, this becomes complex - The water footprint of a nation is equal to the use of domestic water resources, minus the virtual water export flows, plus the virtual water import flows.
