Several Marine Protected Areas have been created in
the world, in part to fulfill one of the United Nations
Convention on Biodiversity goals as to preserve at least
10% of each country’s coastal and marine areas. This
study aims at analyzing military presence in the Brazilian
oceanic islands of Fernando de Noronha, Trindade
& Martin Vaz and São Pedro & São Paulo and how it
interacts with the environmental approach, since the
three encompass Large Scale Marine Protected Areas.
A brief overview about the importance of the islands
to Brazilian geopolitical thinkers is shown, as well as
the theoretical issues regarding the military presence
in preserved environmental areas. Those results are
then applied to the three Large Scale Marine Protected
Areas’ present situation, with the conclusion pointing to
a positive feedback loop, with significant and favorable
results on environmental and military approaches, as
well as regarding geopolitical goals.
