Book excerpt: A agricultura irrigada constitui-se no Nordeste brasileiro uma questaode viabilidade economica para o desenvolvimento regional, principalmente na zona semi-arida. Assim, diante dos antecedentes historicos do desenvolvimento da irrigacao, percebe-se que a maior preocupacao sempre esteve voltada para a maximizacao da renda. No entanto, nunca fizeram parte das decisoes sobre o processo itens importantes como os impactosambientais e a sustentabilidade dessa atividade. Em que pese todas as vantagens e beneficios, a atividade agricola irrigada tem provocado muitos impactos ambientais com serias repercussoes na sustentacao da mesma. Dentre os problemas causados no meio ambiente, a salinizacao e a mais preocupante. No Submedio Sao Francisco, particularmente no Di-poloJuazeiro-Petrolina, localizam-se alguns dos grandes projetos de irrigacao publica, dentre eles o Manicoba, no qual sao observados serios problemas ambientais, que repercutem no desenvolvimento do perimetro. O objetivo central do trabalho foi o de analisar as repercussoes socio-economicas decorrentes da degradacao ambiental em perimetro irrigado.

H. C. Dolabella and published by . This book was released on 1996 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Com a intensificacao do uso dos recursos naturais na regiao dos Cerrados brasileiros particularmente dos solos e dos recursos hidricos, ampliaram-se os riscos de degradacao ambiental, principalmente onde a capacidade de uso destes recursos nao vem sendo respeitada. A bacia hidrografica do Rio Jardim, com areas de 540 km2, esta localizada na mais importante regiao de producao de graos do Distrito Federal e onde a irrigacao com sistemas tipo pivo-central teve grande incremento na ultima decada. Neste trabalho, utilizaram-se imagens de satelites e sistemas de informacoes geograficas (SIG's) para a manipulacao e integracao de dados geoambientais e de uso e ocupacao das terras da bacia. Foram identificadas situacoes onde a exploracao das terras estava em desacordo com a capacidade de uso dos solos. As areas da bacia foram delimitadas quanto ao potencial de geracao de escoamento superficial. Com o metodo do numero-curva do SCS e a tecnica da separacao no hidrograma, quantificaram-se os volumes do escoamento superficial produzidos na bacia no ano agricola 1995/96. As informacoes agronomicas e ambientais da agricultura irrigada por pivo-central, assim como a capacidade de extracao de agua dos vinte e nove equipamentos instalados na bacia foram registradas durante um levantamento de campo. A disponibilidade de agua superficial na bacia foi avaliada a partir das vazoes do Rio Jardim, obtidas de duas diferentes maneiras: (1) a partir de medicoes das vazoes durante dois anos, de 1994 a 1996; (2) atraves de um modelo ...

Download or read book Agricultura irrigada e o licenciamento ambiental written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A agricultura irrigada, como toda atividade antrópica, interfere no ambiente de diferentes modos: (i) a montante com as barragens, canais e linhas de transmissão; (ii) a jusante pela quantidade e qualidade da água liberada que afeta a todos os usuários, do ser humano à flora e fauna; e (iii) no perímetro irrigado com o uso intensivo de agroquímicos, e processos de escorrimento superficial e erosão. Por tudo isto o licenciamento ambiental da agricultura irrigada é obrigatória e definida por lei, e envolve o processo de outorga de uso de água e o licenciamento ambiental propriamente dito. O presente trabalho tem como objetivo avaliar os critérios adotados referentes aos processos de licenciamento ambiental dos projetos de irrigação, com ênfase nos processos de outorga segundo as normas estabelecidas pela ANA, e nos estados de São Paulo, Goiás, e Minas Gerais. A análise das informações mostra divergências entre os processos, com falta de parâmetros e critérios definidos em nível nacional e falta de informações básicas para muitas regiões. Conclui-se que a agricultura irrigada pelo seu caráter de atividade intensiva é impactante ao meio, não apenas pelo consumo de água e resíduos de agroquímicos, mas também pela geração de empregos, alimentos e como potencial filtro de água. Como atividade impactante é preciso ser licenciada para poder ser gerida e o recurso água poder estar disponível em quantidade e qualidade a todos os seus usuários. Para que o licenciamento seja justo, ele precisa ter critérios e parâmetros claros, definidos e uniformes para todo o território nacional. Para que estes parâmetros possam ser definidos, é fundamental que as informações necessárias à sua obtenção, existam e estejam gratuitamente disponíveis. Aos legisladores cabe fundamentar junto a comunidade científica os parâmetros a serem definidos no processo de licenciamento, de modo que possam apresentar equilíbrio entre os seus fundamentos, evitando distorções, mas preservando ao objetivo maior q.
