Environmental Protection Areas: The Case of the Bebedouro Stream Watershed

Abstract

Environmental Protection Areas are legal provisions aiming at the preservation of natural resources through the maintenance of the ecosystem functions. This study aimed to characterize the changes on the land-use between 2002 and 2011, verify the implementation of these legal provisions on the Bebedouro Stream Watershed (Frutal, Minas Gerais), analyze the implications of changes in environmental laws and indicate management options for water resource conservation. For this work the following procedures were performed: land-use mapping of the watershed; investigation on the occupation of the Frutal region; survey of records about the rural properties and Environmental Protection Areas registered. The comparative study of the Bebedouro Stream watershed showed the replacement of large pasture areas by sugarcane plantation; insufficient area of legal provision for biodiversity conservation and increase in the riparian forest during the period studied. Concluding remarks suggest management options for the water uses of the analyzed watershed.

Geotechnologies as an environmental licensing support tool in the state of Piauí, Brazil

“…Through the images, it is seen to verify possible occupations in the legal reserve area of the eastern portion of the project, as well as to verify possible areas of PPA. LRs (Legal Reserves) have as the main function to ensure the differentiated ecological role in the distinct Brazilian biomes and also have an important role in the water infiltration into the soil, as this process favors the recharge of the aquifer (PEREIRA, et al, 2017). In figure 4, through the satellite images, it is verified possible occupations in the legal reserve and PPA area of the enterprise under study, which is not allowed according to the law.…”

“…PPA's are essential for the prevention of negative anthropic impacts on water resources and erosion dynamics. In this sense, it is essential to characterize the riverside forest structure in order to a better understanding of its functions, as suggested by Pereira et al (2017). Given all the mapping of the case under study, geotechnologies applied to environmental licensing help to reduce costs, considering that several analyzes of the property may be performed through satellite images and data integration, thus generating more accessibility information and data accuracy.…”

“…As Áreas de Preservação Permanente (APP) e Reserva Legal (RL) são áreas protegidas por dispositivos legais que visam a conservação dos recursos naturais pela manutenção das funções ecossistêmicas, sendo que a definição de APP está intimamente ligada às características geomorfológicas e/ou às áreas de transição entre os sistemas aquático e terrestre. As APPs ocupam territórios de elevada fragilidade e/ou importância ambiental, e têm forte restrição de uso, tanto em áreas urbanas quanto rurais (PEREIRA et al, 2017). Após habilitadas as camadas desejadas, a função para a impressão do mapa pode ser encontrada no mesmo menu lateral, selecionando o link "Opções".…”

Parlamento, cidadão e políticas ambientais: a percepção dos participantes das audiências públicas na Câmara dos Deputados sobre meio ambiente

“…As unidades de conservação foram concebidas a partir da década de 1930 no Brasil, como resposta ao avanço da industrialização e urbanização. São ancoradas em uma perspectiva biocêntrica, que representa a natureza como um bem comum a ser conservado na sua forma natural, a fim de manter as funções do ecossistema, além de assegurar a qualidade de vida humana (Pereira et al, 2017;Barros et al, 2018). O destaque a essa lei se deve certamente à percepção dos informantes quanto à importância das áreas protegidas, uma das bandeiras de grande parte das entidades e movimentos ambientalistas.…”
