    Análise da inserção das plantas alimentícias não convencionais (PANC) na merenda escolar do município de Marechal Deodoro, Alagoas
    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-01-28) Amorim, Paloma Sena; Melo, Ingrid Sofia Vieira de; http://lattes.cnpq.br/4727408608738222; Calheiros, Altanys Silva; https://orcid.org/0000-0001-5985-6602; http://lattes.cnpq.br/9353777923030637; Melo, Joabe Gomes de; http://lattes.cnpq.br/5180399418500159; Silva, Jose Pedro da; http://lattes.cnpq.br/1491552623899332
    Non-Conventional Edible Plants (PANC) are edible plants that are not commonly part of the daily diet for most of the population but have high nutritional potential and are integral to the cultural traditions of various communities. This study analyzed the feasibility of incorporating PANC into the school meals of Marechal Deodoro (AL) and developed educational materials to disseminate the findings. The research adopted a descriptive approach, combining quantitative and qualitative methods, including bibliographic research, field research, and case studies. Data were analyzed using electronic spreadsheets and action research, allowing for the integration of analysis and practical application. The results showed that 65% of participants were unfamiliar with the term "PANC," yet 54% already consumed parts of these plants, demonstrating practical knowledge despite lacking familiarity with the terminology. All participants expressed interest in cultivating PANC, and 100% were willing to expand their production. Additionally, 83% reported learning about PANC through popular wisdom, highlighting the importance of traditional knowledge. Based on these findings, an educational material featuring recipes was developed to encourage the introduction of PANC into school meals, promoting nutritional awareness and strengthening local food practices.

    Levantamento, identificação e mapeamento de estudos sobre nascentes localizadas no bioma caatinga: uma revisão sistemática de literatura
    (2022) Failla, Sara Carvalho; Calheiros, Altanys Silva; Cunha, Ana Catarina Monteiro Carvalho Mori da; Silva, José Pedro da; Barbosa, Tiago Jorge de Araújo
    The water crisis has grown into a chronic global problem, and the majority of the world's water-related ecosystems are suffering from pollution and degradation. The Caatinga biome is located in the Brazilian semi-arid region, which among the existing semi-arid regions is the most biodiverse and populous in the world. However, it has been one of the most threatened biomes in that country due to the various unsustainable human practices in the region. Therefore, the need for actions and studies dedicated to this ecosystem, which presents little scientific research, is notorious, especially regarding water courses and their sources, which, in addition to being scarce, are vulnerable to human activities and climate change. Mapping studies in the region dedicated to water issues and their recovery, are of paramount importance to stimulate well-timed and targeted actions aimed at reducing, reversing and avoiding environmental degradation, increasing food and water security. Given the above, the present study aimed to carry out a systematic literature review to map the springs located in the Caatinga biome and identify the impacts caused by human actions on their degradation. A literature review was conducted with research carried out on springs in the Caatinga. Searches were carried out using the main available databases, and the data found were mapped in order to highlight regions of low knowledge production. Initially, 1830 scientific papers were found with the search strings utilized, however, not a single scientific paper met all the established inclusion criteria and only 10 papers have partially met the selection criteria. The period of selected researches was from 2006 to 2021 and only five of the nine states that make up this biome have researches on this subject. It should be noted that the very low production made it impossible to carry out a more cohesive and complete systematic literature mapping, evidencing the great scarcity of studies and the importance of new scientific productions on this biome that is so important for the country.

    Uso do índice de vegetação como ferramenta de monitoramento do estado de conservação da Caatinga Alagoana
    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2024-01-31) Nascimento, Marco Antonio Diniz do; Calheiros, Altanys Silva; http://lattes.cnpq.br/9353777923030637; Nascimento, Melchior Carlos do; http://lattes.cnpq.br/3304840348256677; Monteiro, Kleython de Araujo; http://lattes.cnpq.br/0601272599787430
    The Caatinga region undergoes significant modifications in its natural environment, primarily caused by the removal of native vegetation cover, often resulting from illegal deforestation for various purposes and soil exploitation. Therefore, our study presents results on the monitoring of areas covered by native Caatinga vegetation in the Immediate Microregion of Delmiro Gouveia, which includes the municipalities of Delmiro Gouveia, Água Branca, Mata Grande, Pariconha, Piranhas, Olho D’Água do Casado, and Inhapi, located in the hinterland of the Alagoas state. To do so, the research method employed to achieve the results of territorial distribution and quantification of Caatinga vegetation cover is divided into: (i) analysis of the Normalized Difference Vegetation Index - NDVI and Enhanced Vegetation Index - EVI; (ii) analysis of areas adjacent to the 'canal do sertão' (aqueduct project) within a radius of 5 km; (iii) cross-referencing areas embargoed by environmental agencies due to illegal vegetation suppression; and (iv) monitoring land use for the years 2002 and 2022. To obtain the results, images from the Landsat 7 satellite were used, with a spatial resolution of 15 meters (panchromatic) at a cartographic scale of 1:25,000. The analyses obtained through NDVI and EVI did not show significant differences in the distribution of Caatinga vegetation on the ground. The pixel values corresponding to the presence of Caatinga vegetation varied from 0.8 in the year 2002 to 0.6 in the year 2022 for NDVI results, and from 18.8 in the year 2002 to 16.5 in the year 2022 for EVI results. On the other hand, the land use monitoring reveals a 31% reduction in Caatinga vegetation between the years 2002 and 2022, along with anthropized areas, highlighting a 23% growth in agropastoral areas and 11% in exposed soil. In conclusion, the methodology applied on this study yielded satisfactory results for assessing vegetation cover, providing outcomes of environmental, social, and academic interest.
