About the publication - 2021

This Publication brings the limit of the border strip, municipal limits and the positions of the headquarters of the municipalities that make up the Border Strip.
This is an extremely relevant spatial arrangement as it enables the
dissemination of statistical and geoscientific information to support Municipalities within the Brazilian Borders. This product gives support to studies for the development of new specific public policies on economic development, security, defence, infrastructure and social issues, land use, the environment and regional and sustainable integration as a result of the
growth of urban and rural agglomerations in the Border Strip, mainly, by identifying the political-administrative units in Brazil that are under the rules of national security, in particular with regard to public civil engineering works, acquisition or lease of land by a foreign individual or legal entity in these
areas, special land and service grantings, economic exploitation and federal government funding, in addition to supporting bilateral and multilateral agreements, in order to
improve the relations with neighboring countries in the border area.
