Para se chegar a uma proposta de ordenamento territorial no sentido de minimizar os problemas decorrentes dos processos erosivos intensos existentes no litoral paraibano, foi feito um estudo sobre a gênese de duas voçorocas, buscando-se propor uma hipótese baseada nas mudanças do uso do solo, uma vez que a área sob estudo é muito sensível a esse tipo de processo erosivo devido suas características geomorfológicas, climatológicas e de uso do solo. A partir do conhecimento da gênese desses processos erosivos e através de uma cartografia de riscos naturais associados a voçorocas, foi proposto o ordenamento territorial do litoral sul da Paraíba, levando em consideração a possibilidade de criação de corredores ecológicos entre manchas de Mata Atlântica e outros tipos de vegetação nativa em áreas susceptíveis a erosão linear.

Review of the Voçorocamento and Proposed Land Use on the South Coast of Paraiba (Brazil)
ABSTRACT
The main objective of this work is to make a proposal of natural resources management with the aim of generate cartography of natural hazards linked to gullies. The final aim of the research is to create cartography of natural hazards linked to gullies processes in order to create corridors between patches of Atlantic Forest. A description of two voçorocas was executed to formulate a hypotesis aiming to explain the genesis of the erosion based on land uses changes. Finally we explained the recover and stabilitation process on the erosion carried out by the LEPAN (Laboratory of Spacial Analisis - Federal Universtity of Paraiba). Our area is very susceptible to gully processes due his geomorphology, climatology and human occupation.
Keywords: Voçoroca, piping, laterite, erosion.
