Resumo: | In this paper, an analysis of expansion of central pivots irrigation in the estate of Goiás from 1984 to 2015 was performed, with the objective of identifying the conditioning factors of this occupation process and its relation with the water compromise in the study area. For this, images obtained by Landsat satellite sensors and Government data were used to map these facilities. In order to define the water compromise, we also mapped the existing equipment in the Distrito Federal. In addition, was used as reference the Medium Long Term Flow (QMLT), generating a scenario of maximum hydrological potential. As final phase, was performed the analysis of the commitment in catchment basins for public supply, having as a reference the max water right capacity. The state had 3,489 facilities covering an irrigated area of 242,128 hectares in 2015. There was a clear pattern of distribution of irrigation pivots within the state, 60% of existing equipment are located on flat relief terrain with latosols and as close as 10 kilometers of a paved highway. This technique is consolidated in Goiás and tends to expand in the coming years, being a gradual and continuous expansion that facilitates long-term water resource management action. The mapped equipment is located in mid-priced land areas, more distant from the major urban centers, however with the required infrastructure for the production distribution. The area of study (Goiás and Distrito Federal) presented an average water availability in the order of 17 l.s-1 (km²)-1 with a maximum around 32 l.s-1 (km²)-1 and a minimum around 9 l.s-1 (km²)-1 . This availability is distributed in a heterogeneous manner, with the largest flows being in the south of the state of Goiás. The annual surface hydrological potential in the study area is of the order of 178 km³.year-1 . For the state of Goiás, this potential is around 175 km³.year-1 and for the Distrito Federal is approximately 2.5 km³.year-1. The hydrographic region that presented the highest potential volume was the Corumbá, Verissimo and São Marcos rivers, with an offer of the order of 26 km³.-1, a volume that represents about 15% of the total. The average volume required for irrigation by central pivots was 4,800 m³.year-1 .ha-1 , ranging from about 3,800 m³.year-1 ha-1 in the south to around 8,000 m³.year-1.ha -1 in the northeast of Goiás; Resulting in a demand of 1.23 km³-year, with reference to the year 2015. About 68,857 (85%) of the segments analyzed do not present any interference generated by this irrigation sector. This technique also does not present itself as a factor of pressure on the pumping for human supply (using the methodology adopted for granting in Goiás) since only one hydrographic basin presented demand superior to QMLT. |

Para tal, foram utilizadas imagens obtidas pelos sensores do satélite Landsat e dados Governamentais para o mapeamento destes equipamentos. Para definição do comprometimento hídrico, foram mapeados também os equipamentos existentes no Distrito Federal, além disso utilizou-se como referência a Vazão Média de Longo Termo (QMLT), gerando um cenário de potencial hidrológico máximo. Como fase final, realizou-se a análise do comprometimento em bacias de captação para abastecimento público, tendo-se como referência a vazão outorgável. No ano de 2015, o estado apresentou um total de 3.489 equipamentos perfazendo uma área irrigada de 242.128 ha. Observou-se um claro padrão de distribuição da irrigação por pivôs no estado, sendo que 60% dos equipamentos existentes encontram-se em área de relevo plano, com Latossolos e até 10 quilômetros de uma rodovia pavimentada. Esta técnica está consolidada em Goiás e tende a se expandir nos próximos anos, sendo esta uma expansão gradual e continua, fatos que facilitam as ações de gestão dos recursos hídricos a longo prazo. Os equipamentos mapeados encontram-se em áreas de preço médio da terra, mais afastadas dos grandes centros, mas com a infraestrutura necessária para o escoamento da produção. A área de estudo (Goiás e Distrito Federal) apresentou uma disponibilidade hídrica média da ordem de 17 l.s-1 .(km²)-1 com máxima por volta de 32 l.s-1 .(km²)-1 e mínima em torno de 9 l.s-1 .(km²)-1 . Esta disponibilidade distribui-se de forma heterogênea, estando as maiores vazões situadas no sul do estado de Goiás. O potencial hidrológico anual superficial na área de estudo é da ordem de 178 km³.ano-1 . Para o estado de Goiás, esse potencial fica por volta de 175 km³.ano- 1 e para o Distrito Federal é de aproximadamente 2,5 km³.ano-1 . A região hidrográfica que apresentou maior volume potencial foi a dos Rios Corumbá, Veríssimo e São Marcos, contando com uma oferta da ordem de 26 km³.ano-1 , volume que representa cerca de 15% do total. O volume médio necessário para irrigação por pivôs centrais foi de 4.800 m³.ano-1 .ha-1 , variando de cerca de 3.800 m³.ano-1 .ha-1 no Sul até por volta de 8.000 m³.ano-1 .ha-1 no Nordeste de Goiás; resultando em uma demanda de 1,23 km³.ano- ¹, tendo-se como referência o ano de 2015. Cerca de 68.857 (85%) dos segmentos analisados não apresentam qualquer interferência gerada por esse setor de irrigação. Esta técnica também não se apresenta como um fator de grande pressão sobre as captações para abastecimento humano (utilizando-se a metodologia adotada para outorga em Goiás) uma vez que apenas uma bacia hidrográfica apresentou demanda superior à QMLT.Submitted by JÚLIO HEBER SILVA (julioheber@yahoo.com.br) on 2017-04-20T20:22:44Z No. of bitstreams: 2 Dissertação - Lindolfo Caetano Pereira Júnior - 2017.pdf: 6362752 bytes, checksum: 8f0db1d1acd68fca08312485241d33b3 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2017-04-24T13:06:50Z (GMT) No. of bitstreams: 2 Dissertação - Lindolfo Caetano Pereira Júnior - 2017.pdf: 6362752 bytes, checksum: 8f0db1d1acd68fca08312485241d33b3 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2017-04-24T13:06:50Z (GMT).

In this paper, an analysis of expansion of central pivots irrigation in the estate of Goiás from 1984 to 2015 was performed, with the objective of identifying the conditioning factors of this occupation process and its relation with the water compromise in the study area. For this, images obtained by Landsat satellite sensors and Government data were used to map these facilities. In order to define the water compromise, we also mapped the existing equipment in the Distrito Federal. In addition, was used as reference the Medium Long Term Flow (QMLT), generating a scenario of maximum hydrological potential. As final phase, was performed the analysis of the commitment in catchment basins for public supply, having as a reference the max water right capacity. The state had 3,489 facilities covering an irrigated area of 242,128 hectares in 2015. There was a clear pattern of distribution of irrigation pivots within the state, 60% of existing equipment are located on flat relief terrain with latosols and as close as 10 kilometers of a paved highway. This technique is consolidated in Goiás and tends to expand in the coming years, being a gradual and continuous expansion that facilitates long-term water resource management action. The mapped equipment is located in mid-priced land areas, more distant from the major urban centers, however with the required infrastructure for the production distribution. The area of study (Goiás and Distrito Federal) presented an average water availability in the order of 17 l.s-1 (km²)-1 with a maximum around 32 l.s-1 (km²)-1 and a minimum around 9 l.s-1 (km²)-1 . This availability is distributed in a heterogeneous manner, with the largest flows being in the south of the state of Goiás. The annual surface hydrological potential in the study area is of the order of 178 km³.year-1 . For the state of Goiás, this potential is around 175 km³.year-1 and for the Distrito Federal is approximately 2.5 km³.year-1. The hydrographic region that presented the highest potential volume was the Corumbá, Verissimo and São Marcos rivers, with an offer of the order of 26 km³.-1, a volume that represents about 15% of the total. The average volume required for irrigation by central pivots was 4,800 m³.year-1 .ha-1 , ranging from about 3,800 m³.year-1 ha-1 in the south to around 8,000 m³.year-1.ha -1 in the northeast of Goiás; Resulting in a demand of 1.23 km³-year, with reference to the year 2015. About 68,857 (85%) of the segments analyzed do not present any interference generated by this irrigation sector. This technique also does not present itself as a factor of pressure on the pumping for human supply (using the methodology adopted for granting in Goiás) since only one hydrographic basin presented demand superior to QMLT. |
