14. CARACTERÍSTICAS GEOAMBIENTAIS DO MUNICÍPIO DE JAGUARIBE CE E SUAS IMPLICAÇÕES NOS PROCESSOS DE DEGRADAÇÃO AMBIENTAL
The degradation of the natural resources worries studious of diverse areas of the knowledge and the population, in general. In semi-arid regions, as the north-eastern Brazilian, this problematic is aggravated due to the natural vulnerability ally to the process of use and occupation of the land. In the State of the Ceará, the areas more affected by the degr

18. Impactos climáticos regionais da mudança de vegetação no semi-árido do nordeste brasileiro / Impacts climatics regionals of the change vegetation in the simi-arid in the northeast Brazil
In the present study the regional climatic impacts due to the vegetation changes were evaluated, through long term numerical simulations with the regional Eta/SSiB model of the CPTEC/INPE, in which modifications were included to operate in climatic mode. The work was accomplished in two phases. In Phase I, it was evaluated the climatic change of the Northeas
