Resumo: | The present paper approaches desertification within the scope of environmental degradation, in its worldwide, regional and local scales. In this context, Brazilian Northeastern region, specially the Acarau River Basin (Ceara State), was conceived as a territorial unit of territorial management and planning, face natural resources degradation and desertification. The socio-environmental diagnosis which generated discussions here had as theoretical-methodological presuppositions the integrated geoenvironmental analysis, scaffolded by historical and conceptual issues on the desertification phenomenon. In this trajectory, Brazilian Northeast was considered in its environmental complexity, above all, in which refers to its semi-arid portion, being enhanced the National Program of Combat against Desertification and Mitigation of Droughts Effects (Programa Nacional de Combate à Desertificação e Mitigação aos Efeitos das Secas/PAN-BRASIL). The basin in study has the intermittent-seasonal feature and it is placed, specifically, in Center-North of Ceara, occupying a 14.560 Km2 area. About 71,7% of its territory belongs to a semi-arid domain, standing out, within geoenvironmental partitioning, the hinterlands as predominant landscapes. It presents unimportant economic development, with overlapping primary sector. In general, it presents rudimentary technology, which produces low incomes as well as drastic and alarming socio-environmental reflexes among the reigning poverty. This socioeconomic overview contributes to weaken environmental sustainability and it magnifies geoenvironmental vulnerability face the desertification. Desertification consists in an unfolding of environmental degradation, engaged to the historical process of basin`s occupation. It is a remarkable fact impressed on different landscapes under influences of space organizers, with reflexes on the conservation of renewable natural resources, specially, of soils and vegetations, in a conflicted relationship of society x nature. The study also stood out the engaged strategies of contest against desertification, by considering the capacity-support of environmental actives, where were considered, among other purposes, guidelines based on the purpose of geoenvironmental zoning. |

Nesse contexto, o Nordeste brasileiro e, especialmente, a bacia do rio Acaraú (Estado do Ceará), foi concebida como unidade da gestão e planejamento territorial, em face da degradação dos recursos naturais e da desertificação. O diagnóstico socioambiental que ensejou as discussões teve como pressupostos teórico-metodológicos a análise geoambiental integrada, balizada por questões históricas e conceituais sobre o fenômeno da desertificação. Nessa trajetória, o Nordeste brasileiro foi considerado em sua complexidade ambiental, sobretudo, no que se refere a sua porção semi-árida, sublinhando-se o Programa Nacional de Combate à Desertificação e Mitigação aos Efeitos das Secas (PAN-BRASIL). A bacia estudada tem caráter intermitente-sazonal e localiza-se, especificamente, no centro-norte cearense, ocupando 14.560 km². Cerca de 71,7% de seu território é de domínio semi-árido, sobressaindo-se na compartimentação geoambiental os sertões como paisagens predominantes. Mostra desenvolvimento econômico pífio, com primazia do setor primário. No geral apresenta tecnologia rudimentar, que produz baixos rendimentos e reflexos socioambientais drásticos e alarmantes em meio à pobreza reinante. Esse panorama socioeconômico contribui para debilitar a sustentabilidade ambiental e fazer crescer a vulnerabilidade geoambiental em face da desertificação. Esta apresenta-se como desdobramento da degradação ambiental, imbricada ao processo histórico de ocupação da bacia; fato notório impresso nas diferentes paisagens sob influências dos agentes organizadores do espaço, com reflexos na conservação dos recursos naturais renováveis, sobretudo, dos solos e das vegetações, em uma relação conflituosa entre sociedade e natureza. O estudo destacou, também, estratégias integradas de combate à desertificação, considerando a capacidade-suporte dos ativos ambientais, onde foram consideradas, dentre outras propostas, diretrizes pautadas na perspectiva de um zoneamento ecológicoeconômico.Programa de Pós-graduação em GeografiaOrdenamento territorial e ambientalCunha, Sandra Baptista daCPF:09392335768http://lattes.cnpq.br/9402896675191214Rosa, Morsyleide de FreitasCPF:82089205768Souza, Marcos José Nogueira deCPF:00175161372Rosas, Reiner OlíbanoCPF:31220479772http://lattes.cnpq.br/4484335621458630Binsztok, JacobCPF:02348578700http://lattes.cnpq.br/6783064368837751Nascimento, Flavio Rodrigues do2021-03-10T19:10:14Z2009-04-282021-03-10T19:10:14Z2006-04-19info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfapplication/pdfhttps://app.uff.br/riuff/handle/1/17217porCC-BY-SAinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da Universidade Federal Fluminense (RIUFF)instname:Universidade Federal Fluminense (UFF)instacron:UFF2021-03-10T19:10:14Zoai:app.uff.br:1/17217Repositório InstitucionalPUBhttps://app.uff.br/oai/requestriuff@id.uff.bropendoar:21202021-03-10T19:10:14Repositório Institucional da Universidade Federal Fluminense (RIUFF) - Universidade Federal Fluminense (UFF)false |
