A identificacao de Areas Susceptiveis a Desertificacao no Brasil (ASD) tem sido adotada por tomadores de decisao nas Politicas Publicas e nas pesquisas academicas na abordagem da Degradacao da Terra e Desertificacao no Semiarido Nordestino. Considerando que as ASD correspondem as areas semiaridas e subumidas secas, e areas de entorno, consideramos o Semiarido do Ceara para estudo. Este artigo realizou uma breve reconstituicao da analise espacial das ASD entre os anos de 1992 a 2015. Por meio de um comparativo de cinco bases cartograficas e estimativas de areas afetadas pela desertificacao, obteve-se uma representacao espacial das areas mais criticas e dos nucleos configurados no Ceara. A B S T R A C T The identification of of Susceptible to Desertification Areas (SDA) in Brazil has been adopted by decision-makers in Public Policies and in academic research in the approach to Land Degradation and Desertification in the Northeastern Semiarid Region. Considering that the SDA correspond to the semi-arid and subhumid areas, and the surrounding areas, we consider the semi-arid region of Ceara for study. This article made a brief reconstitution of the spatial analysis of the ASD between the years 1992 to 2015. A comparison of five cartographic bases and estimates of affected areas by desertification resulted in a spatial representation of the most critical areas and the configured nuclei in Ceara. Keywords: susceptible to desertification areas, mapping, semi-arid areas, Ceara.
