(UNIFAP - Universidade Federal do Amapá, 2024-02-08) NUNES, Juliana Chagas Gurjão; EULER, Ana Margarida Castro; SANTOS, Sávio Luís Carmona dos; http://lattes.cnpq.br/4120393378913333; http://lattes.cnpq.br/3693054739136900
The açaí (Euterpe o Mart.) is a forest product of great socioeconomic value, its production helps in the composition of the income of countless Amazonian families. The increase in demand for fruits has led to changes in the traditional systems of forest use, especially in floodplain areas, environments of natural occurrence of this species. In this aspect, studies that assess its spatial and socio-environmental dynamics become fundamental for monitoring this activity over time. However, the mapping of this palm tree is difficult due to its occurrence in the forest, traditional methods such as field inventories and interpretation of low-viable images. In these aspects, the study presents the mapping of native açaí groves, in an açaí producing community in the Bailique archipelago, Amapá, a visual interpretation of floodplain forests combined with data from participatory mapping and supervised classification using Artificial Neural Networks (ANN) based on the object-oriented classification technique (GEOBIA). The methodology adopted to invest in the security of an open site and code for classification in very high resolution images Approved for mapping the approved results, confirmed by the moderate Kapptoria index of 0.68, tested in different types of experimentation (stratified random and consistently simple). With the results of the visual interpretation, it was possible to detect the distribution pattern of native triggers in communities under different use regimes, with percentages of coverage ranging from 5% (areas of swiddens) to 10% (areas of management and SAFs). Once the paths to reach the fields of study, limits of a path to the goals will still be needed.
A agenda ambiental na administração pública e a responsabilidade socioambiental na gestão da Universidade Federal do Amapá
(UNIFAP - Universidade Federal do Amapá, 2024-10-16) LIMA, Jonielson Martins de; CHELALA, Cláudia Maria do Socôrro Cruz Fernandes; http://lattes.cnpq.br/2609614137392991; https://orcid.org/0000-0001-9111-9514
The present work addresses the theme of Environmental Public Management and aims to verify whether the Administration of the Federal University of Amapá (UNIFAP) in relation to the compliance with the principles of Environmental Management defined in the Environmental Agenda in Public Administration (A3P), which includes the environmental theme in management, with the purpose of adopting and implementing actions in the area of socio environmental responsibility in its internal and external activities. This is a case study, with a qualitative approach. Bibliographic and documentary research was carried out with the application of questionnaire and interviews with key actors of the University. To achieve the objective of the research, descriptive research was carried out through content analysis. The study presents information about the public environmental management process in force at UNIFAP and sought to analyze whether or not it was adequate to the principles and criteria of A3P. The results obtained reveal that UNIFAP positively meets the criteria and guidelines of the A3P in thematic axes I and II, with effective maintenance actions, acquisition of equipment and investments in sustainable sources. In addition to the implementation of practices such as donation and proper separation of the waste generated. However, the negative points identified were the lack of control of electricity and water consumption by IFES or an educational campaign to raise awareness about saving electricity and water and the lack of mapping of water and energy consumption in UNIFAP buildings, which makes it difficult to implement specific actions to effectively reduce water consumption in each location.
Estudos de alternativas locacionais para implantação de aterro sanitário no Município de Macapá

The generation of Urban Solid Waste (MSW) and its proper management is a challenge for any society. The negative influence of poor MSW management techniques at all stages creates the need to develop adequate environmental, social and economic management systems. The implementation of works for the final disposal of garbage required, as a previous step, the elaboration of sanitary norms to regulate public entities and the availability of spaces destined to the accumulation of garbage in Macapá, in the State of Amapá. Urban Solid Waste Management (MSW) in the city continues to be unfavorable in all stages included in management. Taking these shortcomings into account, we proposed as the general objective of this work to select a reduced number of areas suitable for a sanitary landfill, within municipal limits. Three approaches (environmental, social and economic) were applied to deal with locational alternatives for the sanitary landfill project in the city of Macapá, differentiated by the significance of the elements, which are considered essential to the studies. The results showed that for the correct decision-making in waste management, it is necessary to know the present and future impacts of waste generation, selective collection and final disposal. Estimates that do not take into account the characteristics of waste production can lead to the capacity of waste treatment plants being exceeded with the consequent economic increase. Solid waste buried in the landfill is subject to a series of simultaneous biological, physical and chemical changes. The biological degradation of the organic components starts under aerobic conditions, consuming the air trapped inside the filling; when oxygen is depleted, long-term decomposition remains under anaerobic conditions. Waste degradation is influenced by the degree of compaction, composition of Urban Solid Waste, humidity and temperature; The gas production rate is the main indicator of biological reactions in a landfill. The stabilization time of the residues depends on the intensity of the biological processes; to reach an "inert" state of waste deposited in a traditional landfill. In general, to assess the operation of the landfill, compliance with applicable emission and environmental quality standards and the study or declaration of environmental impact must be monitored. Monitoring of groundwater and biogas should include a period after the decommissioning phase, generally until concentrations are below those indicated by regulations. Taking into account all these long periods to achieve the stabilization of organic matter in landfills, it is necessary to influence and promote the acceleration of these anaerobic phenomena, studying the recirculation of leachate and operating landfills as biodigesters; taking advantage of the biogas generated in them.
Percepção de consumidoras de peixes da região de Macapá-AP sobre os riscos de contaminação por metilmercúrio
(UNIFAP - Universidade Federal do Amapá, 2026-02-20) REZENDE, Jennyffer Vale; SANTOS, Gessica Zila dos; http://lattes.cnpq.br/1894957802286041; https://orcid.org/0000-0003-4821-6567
Methylmercury contamination in aquatic ecosystems represents a serious environmental and public health problem, especially in the Amazon region, where fish is the basis of the local diet. Methylmercury has a high bioaccumulation capacity and can cause irreversible damage to the central nervous system, being even more dangerous for women of childbearing age due to the risks of fetal transfer through the umbilical cord. This study aimed to collect information regarding the perception of fish consumers in the Macapá-AP region about the probable risks of methylmercury contamination. The methodology consisted of a literature review and the application of a questionnaire to 50 participants, women between 18 and 45 years old. The results of the literature review indicated that carnivorous species appreciated in Amapá, such as the tucunaré, present mercury levels that exceed the safety limits of the World Health Organization (WHO). Field research revealed that, although 66% of those interviewed had heard about the contamination, most maintain a weekly fish consumption higher than recommended and are unaware of which species pose the greatest risk. Furthermore, there were reports of symptoms such as headache, mental confusion, and physical imbalance among the participants, but, given the subjectivity of a perception study, there is no evidence linking these symptoms to methylmercury contamination. It is concluded that methylmercury contamination is a topic little known by the target audience, which is concerning because the study region has rivers contaminated by activities related to illegal mining. Therefore, the need for continuous monitoring of the local fish fauna to assess the presence of methylmercury and environmental education actions to raise awareness and ensure the food security of the population was identified.
