Uso e Ocupação do Solo na Reserva Faunística Costeira de Tibau do Sul (REFAUTS), Rio Grande do Norte, Brasil (1984 – 2015) (Land use and occupation at Coastal Wildlife Reserve of Tibau do Sul (REFAUTS), Rio Grande do Norte, Brazil (1984 – 2015))

A Reserva Faunistica Costeira de Tibau do Sul (REFAUTS), praia de Pipa, RN, vem sofrendo transformacoes quanto ao uso e ocupacao do solo, como consequencia do crescimento turistico na regiao. Assim, o objetivo deste estudo foi avaliar o uso e ocupacao da REFAUTS ao longo de quatro decadas. Foram utilizadas quatro imagens de satelite dos anos 1984, 1994, 2004 e 2015. Estas foram classificadas tematicamente de acordo com categorias predeterminadas (agua, vegetacao arborea, vegetacao herbacea e edificacoes/solo exposto). Adicionalmente, foram registrados os empreendimentos turisticos na Zona de Uso Restrito e Controlado da Reserva. A partir da analise temporal, verificou-se que a REFAUTS, com apenas 555 km² de area total, sofreu impactos ambientais negativos. De 1984 a 2015, a porcentagem de area ocupada por vegetacao arborea foi reduzida em 0,57% e por vegetacao herbacea, 4,33%. Entretanto, a area ocupada por edificacoes/solo exposto aumentou em 4,49%. Foram registrados em 2015 cerca de 29 empreendimentos comerciais operando na Zona de Uso Restrito e Controlado da Reserva. Dessa forma, torna-se necessario o ordenamento do uso e ocupacao do solo na REFAUTS, que possui areas frageis como falesias, e ecologicamente relevantes, como remanescentes de restinga e Mata Atlântica.

Thus, the objective of this study was to evaluate the use and occupation of REFAUTS over four decades. We used four satellite images from the years 1984, 1994, 2004 and 2015. These images were thematically classified according to predetermined categories (water, tree vegetation, herbaceous vegetation and buildings/ exposed soil). Additionally, we recorded commercial enterprise in Restricted and Controlled Use Zone of the Reserve. From the temporal analysis, we recorded that REFAUTS, with only 555 km2 of total area, suffered negative environmental impacts. From 1984 to 2015, the percentage of area occupied by tree vegetation was reduced by 0.57% and by herbaceous vegetation, 4.33%. However, the area occupied by buildings/exposed soil increased by 4.49%. We registered in 2015 about 29 commercial enterprise operating in the Restricted and Controlled Use Zone of the Reserve. Thus, it is necessary to organize the use and occupation of the soil in the REFAUTS, which has fragile areas such as cliffs, and ecologically relevant, such as remnants of restinga and Mata Atlântica.
