# Arniqueira

Arniqueira is an administrative region in the Federal District in Brazil. Arniqueira grew substantially between 2000 and 2010, in which the population went from 18,716 to 43,718. In 2015 it was projected that the administrative region would have 46,621 inhabitants in 2020, and in 2021 the region reached 47,045.

## History

The settlement of the Arniqueira Region began in 1990, through the disorderly growth of a sector of farms, which gradually became an urban area that is currently undergoing a process of regularization. Often, both in popular language and in the media, and in official documents, the sector is called "Arniqueiras" (in the plural), the name of the agricultural colony that gave rise to the place, which mentions a stream that bathes the region; nevertheless, the district legislator chose to name the region officially "Arniqueira" (in the singular). Areal, another urban center in the administrative region, originated from the regularization of the former Vila Areal invasion, which took place in 1989. Despite being regularized, this housing nucleus has a deficit of urban infrastructure, such as the absence of colleges and high schools, and the existence of a single Health Center that does not meet the needs of the population, which makes Areal dependent on services from other regions, such as Águas Claras, Taguatinga and Riacho Fundo.
Arniqueira was founded on September 30, 1999, receiving the status of administrative region, according to Law 6391, of September 30, 2019. Thus, it was separated from the Águas Claras region and became the Arniqueira region, the 33rd Administrative Region of the Federal District. Part of the assets, number of servers, operational support, and number of commissioned positions were transferred from the Regional Administration of Águas Claras. These transfers were intended to move the necessary staff for the satisfactory administration of the new Administrative Region created by law.

Despite the economic expansion, Arniqueira faces several problems until the present day, such as the irregularity of the land and the absence of services such as the police station and health unit, in addition to the insufficient number of school places in public education.

### Recent history

In 2020, a partnership was formed between the State Secretariat for Urban Development (Sedur) and the Federal District Development Agency (Terracap) which intended to regularize the Housing Sector of Arniqueira, through a notary registration of the lots and invest in infrastructure in the region. In 2020, in the Arniqueira Administrative Region, an Environmental Control Plan, a Plan for the Recovery of Degraded Areas and Studies of streams and tributaries, due to the formation of erosion and damage to the streams that surround the region, resulting from the irregular occupation of the area, were also prepared, as well as lack of urban planning and the incorrect subdivision of land in Arniqueira.
