PANORAMA DA DESERTIFICAÇÃO NO NORDESTE DO BRASIL: características e suscetibilidades

Francílio de Amorim dos Santos, Cláudia Maria Sabóia de Aquino

Resumo


O processo de desertificação é um fenômeno que atinge diversas áreas do planeta Terra, sendo ocasionada por variações climáticas aliadas ao uso inadequado dos solos em zonas áridas, semiáridas e subúmidas secas. A pesquisa apresenta natureza exploratória e base teórica alicerçada na abordagem sistêmica, com levantamento bibliográfico de artigos publicados em eventos científicos, periódicos, dissertações e teses, de várias áreas, mas principalmente ligadas à Geografia. Os resultados permitem afirmar o emprego de diferentes abordagens e, portanto, de distintos resultados obtidos nas pesquisas relacionadas à desertificação. Contudo, é notório que os aspectos relativos às particularidades físico-ambientais e socioeconômicas das Áreas Suscetíveis à Desertificação (ASD) de cada um dos nove estados do Nordeste brasileiro (NEB) são decorrentes desses fatores e objetiva apontar potencialidades e limitações, com o propósito de orientar ações governamentais para criação de políticas públicas e estratégias para mitigação dos impactos e/ou convivência socioambiental com o referido processo.

DESERTIFICATION PANORAMA IN THE NORTHEAST OF BRAZIL: Characteristics and susceptibilities

ABSTRACT
The desertification process is a phenomenon that affects several areas of the planet Earth, being caused by climatic variations associated to the inadequate use of the soils in arid, semi-arid and dry sub-humid zones. The research presents an exploratory nature and theoretical basis based on the systemic approach, with a bibliographical survey of articles published in scientific events, periodicals, dissertations and theses, in several areas, but mainly related to Geography. The results allow to affirm the use of different approaches and, therefore, of different results obtained in the research related to desertification. However, it is notorious that the aspects related to the physical-environmental and socio-economic particularities of the Areas Susceptible to Desertification (ASD) of each of the nine Brazilian Northeast (NEB) states are derived from these factors and aim to point out potentialities and limitations, with the
purpose of Guide government actions to create public policies and strategies to mitigate impacts and / or social and environmental coexistence with said process.

Keywords: Environmental Degradation; Indexes; Semiarid Region.


PANORAMA DE LA DESERTIFICACIÓN EN EL NORESTE DE BRASIL: Características y susceptibilidades

RESUMEN
El proceso de desertificación es un fenómeno que afecta a muchas áreas del planeta Tierra, siendo causado por los cambios climáticos combinados con el uso inadecuado de la tierra en el sub-áridas, semiáridas y secas. La investigación exploratoria y presenta a tierra base teórica del enfoque sistémico a los artículos publicados en la bibliografía en eventos científicos, publicaciones periódicas, disertaciones y tesis en varias áreas, pero en su mayoría relacionados con la geografía. Los resultados nos permiten afirmar el uso de diferentes enfoques y por tanto diferentes resultados obtenidos en la investigación relacionada con la desertificación. Sin embargo, es evidente que los aspectos de las características físicas y ambientales y socio-económico de las Áreas Susceptibles a la desertificación (ASD) de cada uno de los nueve estados del Noreste de Brasil (NEB) son el resultado de estos factores y el punto objetivo y limitaciones potenciales, con el fin de orientar las acciones del gobierno para crear políticas públicas y estrategias para mitigar los impactos y / o convivencia del medio ambiente con ese proceso

Palabras clave: La Degradación Del Medio Ambiente; Índices; Región Semiárida.
