O objetivo deste memorial é relatar a minha trajetória acadêmica por meio de uma análise reflexiva e sistemática dos principais aprendizados, desafios, eixos e temas abordados ao longo dos semestres. A metodologia utilizada baseou-se nas memórias acadêmicas revisitadas a partir do processo vivido, dos materiais produzidos e textos indicados durante o curso, possibilitando a construção de uma narrativa que integrasse os aspectos mais marcantes da formação. Os principais instrumentos utilizados foram os relatórios produzidos, as viagens de imersão, os arquivos audiovisuais, as aulas remotas, os cadernos e os registros das culminâncias. Este memorial é composto por três partes: na primeira parte, apresento a minha identidade, na qual descrevo de forma sintetizada os momentos da minha vida pessoal, tanto no estado no Rio Grande do Norte, como em Pernambuco, e a trajetória educacional, onde relato o início da minha vida educativa, a realização dos cursos técnicos e a minha entrada na universidade. Na segunda parte, trago a linha do tempo, destacando os desafios, os principais aprendizados, eixos e temas mais relevantes do primeiro ao oitavo período; os estágios supervisionados obrigatórios, realizados no primeiro e oitavo período; e os dois temas de aprofundamento, em diálogo com as experiências vividas e com os diferentes pontos de vista acerca dos temas. Na terceira e última parte, apresento o fechamento da minha trajetória acadêmica, retomando os desafios e os aprendizados, concluindo essa trajetória afirmando que a minha caminhada como agroecóloga e educadora continua no aprendizado, na partilha e na contribuição para a construção de uma sociedade mais justa e sustentável.Item Uma análise histórica da mulher na agricultura familiar e sua relevância para preservação da biodiversidade genética e ecológica(2024-03-05) Silva, Jenifer Carla Borges da; Freitas, Nara Suzy Aguiar de; http://lattes.cnpq.br/6891650997818766; http://lattes.cnpq.br/0352343973672028Family farming, essential for food security and sustained by ancestral practices, is marked by the fundamental role of women in the conservation of genetic diversity and the cultivation of traditional varieties. These varieties are vital for the resilience of ecosystems against environmental challenges, but are threatened by modern agriculture and genetic erosion. Therefore, this research aims to analyze the female contribution to family farming and its impact on biodiversity conservation. Using a meta-analysis methodology, the research examines 60 scientific publications, including articles, dissertations, theses, and final papers, to identify trends and gaps in knowledge. Approximately 80% of the studies analyzed include specific information about gender, with 18% focusing specifically on women, reflecting the national reality of female participation in agriculture. Correlation analyses and chi-square tests were applied to investigate the relationship between gender and the use of agrochemicals and organic practices, finding no statistically significant associations. Multiple Correspondence Analysis (MCA) was employed to explore the relationships between seed varieties, methods of acquisition, and geographical locations of farming families in Brazil. The results reveal systemic barriers faced by female farmers, such as limited access to financial resources and agricultural credit. The study also highlights seed selection based on immediate characteristics, the cultural importance of seeds, and the need for supportive policies for family farming. A crucial aspect is the ongoing genetic segregation of Creole seeds, which allows them to adapt to environmental changes and resistance to pests and diseases, although it may result in inconsistencies in production. The artificial selection of Creole seeds by farmers can lead to the loss of valuable genes, underscoring the urgency of expanding the presence of specialized technicians. Family farming in Brazil is revealed in a complex manner, influenced by historical, cultural, and environmental factors.Item Diagnóstico de redes de sementes florestais no Brasil(2024-02-07) Silva, Ana Clara Santana; Santos, Marcone Moreira; http://lattes.cnpq.br/3284707164193715; http://lattes.cnpq.br/5674898094215400Forest seed networks play a fundamental role in the preservation and restoration of forest ecosystems, representing initiatives aimed at conserving native plant species in different biomes. These networks work collaboratively, with the active participation of various social actors, such as local communities, non-governmental organizations (NGOs), research institutions and government entities. The objective of this study was to carry out a comprehensive mapping of forest seed networks in Brazil, with the aim of understanding their distribution, structure and impact on the conservation and restoration of forest ecosystems. For this survey, four methods were adopted: research on the networks' web pages, analysis of Instagram profiles and application of questionnaires, consultation of RENASEM/MAPA with specific filters and analysis of academic articles on Scholar Google, using specific keywords. As a result, it was possible to map twelve forest seed networks in Brazil, identifying four main actors involved. A significant concentration of these networks was evident in the Center-West and Southeast regions of the country, with a significant diversity of native species from the Cerrado, Atlantic Forest and Amazon biomes. The main research institutions and non-governmental organizations were highlighted as the main actors involved in this context.Item Acompanhamento técnico das atividades da terra tecnologia agrícola Ltda – Jaboatão dos Guararapes/PE(2023-05-04) Amorim, Luiz Eduardo Santos de; Melo, Roberto de Albuquerque; http://lattes.cnpq.br/9419474898249921; http://lattes.cnpq.br/5032336323185051Item Relatório de Estágio Supervisionado Obrigatório. Práticas laboratoriais de análise de sementes - IPA(2022-05-27) Carvalho, Robson Oliveira de; Santos, Mércia Virginia Ferreira dos; http://lattes.cnpq.br/9565465836878202Item Seleção de progênies via germinação de sementes de Mimosa caesalpiniifolia B. sob estresse salino(2022-05-26) Ordonho, Larissa Santiago Ritt; Gallo, Ricardo; http://lattes.cnpq.br/5160912065817980; http://lattes.cnpq.br/4822409457783849Mimosa caesalpiniifolia Benth., known as sabiá, is a native forest specie of Caatinga belonging to the Fabaceae family. Species that develop in arid and semi-arid regions, such as sabiá, usually encounter adverse conditions for germination and emergence, such as high soil salinity and water deficit. Thus, the objective of this work was to verify whether it is possible to select progenies of M. caesalpiniifolia that are tolerant to the stress caused by doses of saline solutions in the early stages of development. Seeds were collected from 16 matrices located in different states (PE, PI, CE, RN), four per state. The experiment was carried out in the forest seed analysis laboratory at the Federal Rural University of Pernambuco (UFRPE). To simulate saline stress, NaCl solutions were used, with osmotic potentials of 0.0; -0.2; -0.4; -0.6; -0.8; -1 MPa. Percentage and germination speed index, length and dry mass of shoots and roots and percentage of abnormal seedlings were evaluated. The experimental design was completely randomized with four replications of 32 seeds for each potential. After carrying out the evaluations, the maximum dose of pre-established tolerance was reapplied in four replications of 25 seeds from each provenance to identify the genetic divergence in terms of tolerance to saline stress. For the germination percentage, the values were adjusted to the quadratic regression model and for the germination speed index, the data were adjusted to the decreasing linear regression model, reducing as the osmotic concentration increased. Salinity reduced the germination and vigor of M. caesalpiniifolia seeds, decreasing the characters evaluated at the lowest osmotic potentials. The germination test with sabiá seeds proved to be effective for determining tolerance to salt levels (NaCl), the species M. caesalpiniifolia tolerates low osmotic concentrations of sodium chloride and the critical level selected was -0.4 MPa. Through the Mulamba and Mock index, it was possible to select the P1-CE, P2-PI, P3-RN, P1-PE and P1-PI progenies in early stages of development that showed tolerance to salinity levels for the production of seedlings.Item Relatório de Estágio Supervisionado Obrigatório - ESO.
