“…Among the usable conservation practices, contour planting is one of the viable options to preserve soil erosion processes, according to Santos et al [3], Griebeler et al [4], Leite et al [5], and Xavier et al [6]. Contour planting contributes to sustainability by controlling the loss of soil particles so that the soil becomes more resistant to the erosive process [7].…”

Contour planting minimizes soil degradation, making agricultural production more sustainable. Currently, geotechnologies can provide more precise and fast data from relief than rudimentary data acquisition for agricultural management. Thus, the objective of this work was to analyze the similarities between contour lines from topography and Remotely Piloted Aircraft, using the Hausdorff distance algorithm. This study was carried out in the period between January 2020 and November 2021 in four localities in the State of Rio de Janeiro, Brazil: two areas located in the municipality of Bom Jardim and two areas in the municipality of Seropédica. Data were acquired through a conventional topographic survey and an aerial photogrammetric survey by Remotely Piloted Aircraft. From the acquired field data for the studied areas, the Digital Elevation Models were generated with a spatial resolution of 0.20 m and the contour lines with an equidistance of one meter. The contour lines obtained by both techniques were superimposed and their similarity was verified using the Hausdorff distance. The results show that there was a better similarity among the contour lines in areas with a very rugged relief than in a smooth relief. Also, the lowest altimetric differences observed in the Digital Elevation Models were associated with the smallest Hausdorff distance. These adjustments correspond, respectively, to the segments between the contour lines with the best and the worst individual similarity for each area. We observed that the similarity between the contour lines from topography and RPA yielded slope differences lower than 6.1% for at least 95% of all studied areas. The Hausdorff distance analysis allowed us to conclude that contour planting can be performed from data obtained via Remotely Piloted Aircraft, provided that vertical accuracy analysis controls the quality of the Digital Elevation Models.

Na tentativa de imprimir significado a aprendizagem no ensino de Ciências e torná-lo mais eficaz e atrativo, os professores devem continuamente repensar e aperfeiçoar suas práticas pedagógicas, adotando instrumentos didáticos que permitam a realização e facilitação da aprendizagem, com abordagens que conduzam à reflexão sobre as temáticas ambientais, de forma contextualizada. Assim, esta pesquisa objetivou utilizar plantas carnívoras como ferramentas didáticas em prol de despertar a sensibilidade ambiental dos alunos de duas escolas de Quirinópolis, Goiás. Para tanto foi realizada uma intervenção pedagógica envolvendo a exposição sobre alguns conceitos ambientais e uma atividade prática com plantas carnívoras. Antes e posterior à execução da intervenção pedagógica os alunos responderam questionários e fizeram desenhos, os quais auxiliaram na verificação da validade do método didático empregado. Verificamos que a atividade proposta possibilitou a eles conhecer mais sobre plantas carnívoras, observando a importância ecológica delas e a estreita relação da diversidade deste grupo com o estado de conservação do ambiente em que elas vivem, oportunizando reflexões sobre nossas atitudes que impactam diretamente o meio ambiente. Antes de conhecerem as plantas os desenhos dos alunos as representavam como seres “humanizados”, “comedores de gente”, de caráter perigoso, apresentando risco à humanidade. Após a aula prática, os desenhos já ilustravam as reais características morfológicas destes vegetais. Diante dos dados, podemos inferir que o uso de plantas carnívoras consiste em uma prática atrativa para o ensino de Ciências, em especial de botânica, abordando diversos temas de maneira contextualizada e interdisciplinar, favorecendo uma aprendizagem não fragmentada.
