Resumo: | For many years, crop and livestock production were the main causes of deforestation in the Amazon Region, mainly after the developmentalist policies for the Amazon region in the 60s. In this context, the objective was to analyze, from 2002 to 2017, the spatiotemporal dynamics of land use and land cover in Maranhão municipalities located in the Legal Amazon. The study took place in 170 municipalities that are part of the territory of the Legal Amazon. For the application of the correlation coefficient, data referring to deforested areas, total area used in agriculture and number of cattle were used. The data of territorial area and population estimation of the municipalities of larger deforested area were also used. Deforestation in the Legal Amazon in Maranhão was significantly reduced by 131,428 hectares from 2002 to 2017. In contrast, the number of cattle and the area used for agriculture increased from 4.33 to 7.098. million and 1.052 to 1.573 million hectares, respectively. Deforestation of the Legal Amazon in Maranhão, in 16 years, was largely (70%) concentrated in 25 municipalities, mainly those located near important federal highways or with easy access to other states, such as Pará. Although, deforestation indicators in Legal Amazon located in Maranhão, indicate that there is a reduction in 16 years, it is necessary to pay attention to sustainable development in agriculture, that is, balance between the economic, ecological and social, because there is much that can still be preserved. Appropriate environmental oversight in state boundary areas, which show a strong tendency to environmental impacts associated with deforestation, is also important. |

Neste contexto, objetivou-se analisar no período de 2002 a 2017, a dinâmica espaço-temporal do uso e cobertura do solo nos municípios maranhenses situados na Amazônia Legal. O estudo aconteceu em 170 municípios que fazem parte do território da Amazônia Legal. Utilizou-se para aplicação do coeficiente de correlação, os dados referentes às áreas desmatadas, área total utilizada na agricultura e quantidade de bovinos. Empregou-se também os dados de área territorial e estimativa populacional dos municípios de maior área desmatada. Observou-se que o desmatamento na Amazônia Legal, no Maranhão, teve expressiva redução de 131.428 hectares, entre os anos de 2002 a 2017. Em contraste a isso, o número de bovinos e a área utilizada na agricultura aumentaram de 4,33 para 7,098 milhões e 1,052 para 1,573 milhões de hectares, respectivamente. O desmatamento da Amazônia Legal no Maranhão, em 16 anos, esteve amplamente (70%) concentrado em 25 municípios, principalmente os localizados próximos a importantes rodovias federais ou com fácil acesso a outros estados, como o Pará. Embora, os indicadores de desmatamento na Amazônia Legal situada no Maranhão, indiquem que há redução em 16 anos, é necessário atentar ao desenvolvimento sustentável na agropecuária, ou seja, equilíbrio entre o econômico, ecológico e social, pois há muito que pode ser preservado, ainda. Também é importante a adequada fiscalização ambiental em áreas de divisa do estado, que demonstram uma forte tendência a impactos ambientais, associados ao desmatamento.Editora Verde2019-11-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/655010.18378/rvads.v14i3.6550Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 14 No. 3 (2019); 443 - 452Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 14 Núm. 3 (2019); 443 - 452Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 14 n. 3 (2019); 443 - 4521981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/6550/6588https://www.gvaa.com.br/revista/index.php/RVADS/article/view/6550/6590Copyright (c) 2019 Carlos Augusto Alves Cardoso Silva et al.info:eu-repo/semantics/openAccessSilva, Carlos Augusto Alves CardosoOliveira, Kamilla Andrade deCastro, Maria Patrícia PereiraOliveira, Ana Karla da SilvaSousa, Washington da SilvaAlmeida, Edmilson Igor Bernardo2022-11-02T01:56:33Zoai:ojs.gvaa.com.br:article/6550Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:35.639402Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
