About the publication - 2022

This publication includes the borderland strip, municipal borders and positions of the capitals of the municipalities that comprise the Borderland Strip.

It is an extremely relevant spatial arrangement as it allows to release statistical and geoscientific information supporting the Municipalities within the Brazilian Borderland Strip. This product supports the studies for the development of new specific public policies about the axes of economic development, security, defense, infrastructure and social issues, land use, environment and regional integration, and sustainable as a consequence of the growth of urban and rural agglomerations in the Borderland Strip, mainly by pinpointing the Brazilian political-administrative units under the rules of national security, especially in terms of public works of civil engineering, acquisition or leasing of land by foreign physical or legal persons, special concessions of land and services, economic exploitation and financial aid from the federal administration, as well as subsidizing bilateral and multilateral agreements to improve relations with neighbor countries in the borderland strip.
