    Risco de extinção das abelhas no Brasil: causas, consequencias e soluções
    (2025) Azevedo, Leandro Melo de; Pinheiro, Pablo; Pinheiro, Pablo; Christiano, Daniel; Lenz, Tiago de Moraes
    Bees are essential to maintaining biodiversity and the harmonious functioning of the planet. It is based on this premise that concerns arise about potential threats that may affect them. This paper shows that habitat loss, use of pesticides, diseases, poor nutrition, commercial agriculture, illegal trade in beehives, and light pollution are the main contributors to the advancement of the problem in question. It also presents the possible consequences resulting from the absence of these pollinators, such as the impacts on pollination and agriculture, loss of biodiversity, imbalance in ecosystems, and food and nutritional crises. Finally, the creation and preservation of habitats, regulation and control of pesticide use, monitoring and research on bee health, encouragement of organic agriculture, agroecological practices, environmental education, and public awareness are highlighted as preventive strategies that can be applied in order to circumvent the risk of extinction faced by these insects.

    Utilização de imagens para identificação de alterações no uso e cobertura do solo do município de Murici - Al
    (2024-09-10) Silva, Edenilson Ferreira da; Santos, Erick Phelipe Ramos dos; Lima, André Suêldo Tavares de; Silva, Ivanildo Claudino da ; Santos, Patrícia da Silva
    The present study uses geoprocessing and remote sensing technologies to identify changes in land use and cover in the reference years (1992, 2002, 2012 and 2022) in Murici, Alagoas. The methodology used involves downloading images referring to land use and land cover maps in Google Earth Engine (GEE), through the MapBiomas tool, in its 8.0 collection, which uses annual mosaics of Landsat images based on predefined periods (collections) with spatial resolution of 30m x 30m for supervised classification of multispectral images. Using the Semi-Automatic Plugin (SCP) add-on to QGIS 3.26, each land use and land cover map was subjected to post-processing using the "Cross Classification" tool, allowing mapping and area calculation of use classes and soil cover, as well as transition data between classes, making it possible to ascertain the balance of gains and losses from one class to another between the decades analyzed. Between 1992 and 2022, a significant reduction in forest and savanna areas was identified, possibly driven by the expansion of agricultural activities. At the same time, urbanization has expressed progressive growth, which results in the reduction of other classes of use and coverage and can drive waterproofing, soil degradation and changes in water bodies. It is imperative, therefore, to adopt public policies that reconcile environmental conservation with local needs.
