Design Strategy of Emergency Pools at Source Water Protection Areas

The pollution problem arising from the flushing of initial rainwater and wastewater from accidents while transporting dangerous goods to source water protection areas needs to be solved as soon as possible. Therefore, the design of corresponding environmental protection measures should be considered in the engineering design stage. It is necessary to analyze the specific work in combination with engineering examples. Under this background, this paper first briefly expounds the precautions in accident risk analysis and the design of tank capacity and tank body. Finally, by analyzing actual cases, this paper systematically studies the design strategy of emergency pool in source water protection area, hoping to provide new development ideas for the upgrading of relevant work.

Ecological Impacts of the African Catfish Clarias Gariepinus at Environmental Protection Area in Southeastern Brazil

The African catfish (Clarias gariepinus) is considered one of the most important species of catfish for aquaculture. It has a great capacity to withstand several stress factors, such as harsh abiotic conditions, in addition to wide feeding flexibility. However, the species was detected in the Guapimirim Environmental Protection Area in southeastern Brazil, threatening native fish diversity and ecosystem functioning of this ecosystem. In 2018, during the dry and wet seasons, samples of the fish community were collected at thirty-two sites of the Guapi-Macacu River, in addition to abiotic variables (salinity, pH, temperature, turbidity, dissolved oxygen, and transparency) to diagnose which factors influence the distribution of the alien species along the river. Multivariate analyses indicated that African catfish dominate the region in the buffer zone to the Environmental protection area, benefiting from higher levels of dissolved oxygen and temperature. However, C. gariepinus does not dominate yet the most protected area of Guapimirim, where the highest percentage of native fish species inhabit. Climate change associated with changes in abiotic factors might significantly contribute to the dominance of the invasive alien species in this protected area, which might colonize the entire river.

Levantamento Florístico da Área de Proteção Ambiental (APA) da Lagoa da Maraponga, Fortaleza, Ceará, Brasil

A Área de Proteção Ambiental (APA) da Lagoa da Maraponga é uma unidade de conservação municipal localizada no bairro Maraponga, município de Fortaleza, estado do Ceará. Composto predominantemente por um ecossistema lacustre, no qual se destaca a Lagoa da Maraponga, com área de 31 hectares, ameaçada pela ação antrópica, fazendo com que a conservação se torne uma prioridade. Objetivou-se fazer o levantamento florístico da APA da Lagoa da Maraponga e elaborar um guia de campo. Foram realizadas coletas botânicas, observações de campo, fotografias e identificações das espécies. Registraram-se 98 espécies pertencentes a 82 gêneros e 37 famílias botânicas. As famílias mais representativas foram Fabaceae (18 spp.), Malvaceae (13 spp.), Asteraceae (dez spp.), Rubiaceae (cinco spp.), Arecaceae, Convolvulaceae e Solanaceae (quatro spp., cada). Constatou-se que o hábito das espécies tem como predomínio o porte herbáceo (41 spp.), seguido de espécies subarbustivas (19 spp.), arbóreas (17 spp.), arbustivas (dez spp.), trepadeiras (sete spp.) e palmeiras (quatro spp.). Conclui-se que esta área tem demonstrado que mesmo com a interferência humana e o grande avanço da urbanização em seus arredores, a flora local apresenta elevada riqueza de espécies nativas que precisa ser conservada, mantida e reconhecida por políticas públicas e pela sociedade, as quais podem ser auxiliadas pelo guia de campo elaborado. Floristic Survey of the Environmental Protection Area (EPA) of Maraponga Lagoon, Fortaleza, Ceará, Brazil A B S T R A C TThe Maraponga Lagoon Environmental Protection Area (EPA) is a municipal conservation unit located in the Maraponga neighborhood, in the municipality of Fortaleza, state of Ceará. Composed predominantly of a lake ecosystem, in which the Maraponga Lagoon stands out, with an area of 31 hectares, threatened by anthropic action, prioritizing conservation. The objective was to carry out the floristic survey of the EPA of Maraponga Lagoon and to prepare a field guide. Botanical collections, field observations, photographs and species identification were carried out. A total of 98 species belonging to 82 genera and 37 botanical families were registered. The most representative families were Fabaceae (18 spp.), Malvaceae (13 spp.), Asteraceae (ten spp.), Rubiaceae (five spp.), Arecaceae, Convolvulaceae and Solanaceae (four spp., each). It was found that the habit of the species predominates the herbaceous size (41 spp.), followed by sub-shrubs (19 spp.), trees (17 spp.), shrubs (ten spp.), climbing plants (seven spp.) and palm trees (four spp.). It’s concluded that this area has shown that even with human interference and the great advance of urbanization in its surroundings, the local flora has a high number of native species that need to be conserved, maintained and recognized by public policies and society, which can be assisted by the field guide prepared.Keywords: Urban biodiversity, conservation, vegetable diversity, richness, conservation unit.

Para quem é a proteção ambiental? Disputas territoriais entre a Vale e comunidades camponesas: O caso da APA do Rio Gelado em Carajás (PA)

Desvendar a relação de poder assimétrica entre Neoextrativismo e o Campesinato na região mineradora de Carajás, é nesse viés em que consiste o esforço de pesquisa demonstrado, parcialmente, neste artigo. Destacamos para isso, ser necessário a relação entre a dimensão ambiental da Questão Agrária na Amazônia. No primeiro semestre de 2021 adentramos na Área de Proteção Ambiental do Igarapé Gelado, APA do Gelado, localizada na Floresta Nacional de Carajás – FLONACA, no Sudeste do Pará, l0cus do nosso estudo. Para a coleta de dados, utilizamos documentos institucionais (IBAMA, ICMBio e Vale/SA). Contudo, a etapa principal da nossa pesquisa foi o trabalho de campo. Utilizamos como técnica de pesquisa, gravações de áudio e entrevistas semiestruturadas, a qual busca dialogar entre o momento da conquista da terra e a relação estabelecida entre a Vale e as famílias camponesas. Além disso, utilizamos fotografias para aproximar o leitor da realidade imagética de nossa pesquisa. Em outros momentos, o uso do diário de campo foi imprescindível. Percorremos os lotes dos colonos que ainda resistem no território. Discorremos sobre isso porque muitas famílias sofreram impactos profundos em seu modo de vida e de produção e, logicamente, em sua reprodução social camponesa. Barragens, vigilância e uso restrito ao território na APA são alguns dos elementos constrangedores às territorialidades dessas unidades familiares. Os dados nos induzem a problematizar a ação da prática mineradora, promovida principalmente pela Vale, que reforça as contradições próprias da sua atividade, causando problemas ambientais ao converter os bens comuns em uma lógica de acumulação permanente. Como consequência, intensifica-se os conflitos territoriais e, contraditoriamente, se abrem possibilidades para a permanência das famílias camponesas que têm resistido no território e construindo sua liberdade tecidas no trabalho diário com a terra.

Abstract Our research efforts involve revealing the asymmetrical power relations between neo-extractivism and the peasantry in the mining region of Carajás, as demonstrated in part in this article. In the first semester of 2021, we entered the Carajás Environmental Protection Area FLONACA in the southeast of Pará, the main site of our study. We used institutional documents from IBAMA, ICMBio and Vale/SA to collect data. However, the principal phase of our research was fieldwork. Our research techniques included using audio recordings and semi-structured interviews about the moment of winning land and about the relation between Vale and the peasant families. In addition, we used photography to bring the reader closer to the visual reality of our research. In other moments, the use of field notes was essential. We say this because many families suffered profound impacts to their livelihoods and their production and, logically, in their social reproduction as peasantry. Dams, security, and restrictions to land use in the environmental protection area are some of the elements constraining the territoriality of these family units. The data leads us to problematize the mining activity promoted primarily by Vale, which reinforces the very contradictions of its own activity, causing environmental problems upon converting common goods into a permanent logic of accumulation. As a result, territorial conflicts intensify and, paradoxically, possibilities to remain emerge for families who have resisted within the territory and built their freedom through daily labor with the land.

Notes on the life history of Aguna megacles megacles (Mabille, 1888) (Lepidoptera: Hesperiidae: Eudaminae) feeding on Bauhinia species in the State of Alagoas, Brazil

Eudaminae Mabille, 1877 (Hesperiidae), recognized as subfamily recently, is rich in Brazil. It is along the Neotropical Region where a significant part of the diversity is found, however, information that involves the biology of species is poorly yet. This paper gathers new bioecological data of an Aguna species from the municipality of Maceió (Alagoas, Brazil), close to the Environmental Protection Area of “Catolé” and “Fernão Velho”, a remnant of Atlantic Forest. Leaves containing eggs were collected in a peri-urban area (9° 33’ 26” S, 35° 46’ 36” W) and taken to laboratory to observe post-embryonic development. Larvae were also collected from another host plant in an intra-urban area (9° 39’ 40” S, 35° 41’ 58” W). The specimens were identified as Aguna megacles megacles (Mabille, 1888) and the two Fabaceae as Bauhinia pentandra (Bong.) D. Dietr. and Bauhinia monandra Kurz. from exsiccates deposited at the Herbarium. Rearing from the eggs collected on B. pentandra exposes a post-embryonic development that lasted 53.4 days for six larval instars individuals, and 46 days for the five larval instars specimen. The larvae built a shelter since the first instar and in laboratory conditions they preferred pupate on the base of the cage. This is the first report of development features for A. m. megacles, including six and five larval instars, as well as a new locality for the State of Alagoas, and two more host plants of Bauhinia suggesting specialist behavior.

Creation of an environmental protection area in a public supply source: possibilities and challenges in Cianorte - Paraná

This work analyzed the contribution that the creation of Environmental Protection Areas (EPA) may bring to the conservation of hydrographic basins used as public water sources. The object of study of this work was the hydrographic basin of the Ligeiro River which, by 2022 onwards, will be the new source of public supply in the city of Cianorte-Paraná, replacing the hydrographic basin of the Bolívar stream. The latter has environmental impacts caused mainly by the expansion of urban areas and inadequate practice of land use, occupation, and management, which affects the population’s supply, particularly on days with high levels of rainfall. The study area involved the creation of two municipal EPAs in the hydrographic basin of the Ligeiro River, located in the municipalities of Araruna and Cianorte, with areas of 209.76 km² and 219.82 km², respectively. It is believed that the creation of Environmental Protection Areas in the Ligeiro River hydrographic basin will also present challenges, but it will enable the conservation of natural resources and, especially, of water resources, given the quality of the water. It is expected that these actions will help to minimize or even prevent, in the future, the Ligeiro river hydrographic basin from being as or more impacted as the Bolivar stream basin.

Landscape Works. Balancing Nature and Culture in the Pantelleria National Park

Traditional agricultural practice and peculiar geographical features in the Mediterranean basin have not only moulded cultural and heritage values, but also created the conditions for the development of habitats to be protected. Therefore, Landscape proves a suitable concept both for the enhancement of cultural features and for nature conservation. The aim of this work is to apply the landscape approach to the Pantelleria National Park, providing the opportunity to reflect upon and discuss whether and how to encompass rural landscape planning and management within the broader context of natural values, offering a frame of reference for the zoning of the future Park Plan. Specifically, the research aims to define zoning categories, typical to protected areas planning, using criteria related to landscape features and patterns, environmental quality, traditional agriculture, architectural heritage. Established in 2016, the Pantelleria National Park is the most recent Italian National Park and the first one in Sicily. The Park covers 79% of the island, encompassing two sites of Community Importance as well as one Special Protection Area belonging to the Natura 2000 network. Pantelleria is a microcosm gathering a great variety of natural and human-made landscapes characterized by high levels of complexity embodying the antagonism of two protected ‘noble interests’: Nature and the environment on the one hand, Culture framed as traditional rural practices on the other. The main challenge of the new-founded National Park is to combine quality and values relating to the domain of Nature, which is expanding, with those expressed by Culture, represented by a wide array of historical rural values at risk due to ongoing abandonment of most remote areas.

Comprehensive Evaluation Model of Environmental Quality in Ecological Reserve

The environmental quality of the ecological protection zone directly affects the water quality and air quality of the area, thereby affecting the quality of people’s life. This paper constructs the evaluation index system of the environmental quality of the ecological protection area and determines the classification standards of each index, proposes the extension evaluation method of the environmental quality of the ecological protection area, and uses the entropy weight method to determine the weight of each level of index. Its purpose is to understand the development trend of environmental quality in all aspects of the ecological reserve through the dynamic evaluation of the environmental quality of the ecological reserve, so as to take corresponding countermeasures to promote the healthy development of the area. The constructed model was used to dynamically evaluate the environmental quality of the ecological reserve in Zhangjiakou City from 2008 to 2019. The research results show that the environmental quality gaps in different aspects of the ecological reserve of Zhangjiakou City are relatively large, and the overall regional ecological environment characteristic value is decreasing year by year, reflecting that the environmental quality of the ecological reserve of the region is getting better year by year.
