The movie was presented to support environmental education classes at the University of Brasilia. Over a period of five years, 210 Brazilian undergraduate and graduate students answered questionnaires after watching it. The results demonstrate that the movie helped to accomplish environmental education goals: the comprehension of the role of scientific knowledge in solving socio-environmental problems, the impact of human activities on biodiversity, the novelty of the integrative interplay of different disciplines, and the importance of values in awareness.

Here, we present a qualitative model to compare impacts of two managements, intensive farming and traditional management, on bird community inhabiting a mosaic of Cerrado-forest landscape. We built qualitative reasoning model using Garp3 simulation engine. Three groups of species were considered based on their differential use of the forest-savanna mosaic: forest specialist, forest generalists and non forest. Our results suggest the intensive agriculture leads to the decline non-forest and forest specialist, while forest generalist might either decline or be kept stable. On the other hand, traditional management may lead to either a decline or maintenance of Non forest and the maintenance of both forest groups. The substitution of traditional management for intensive agriculture may negatively affect birds. Qualitative reasoning can indeed be used to predict behaviors of biological under different scenarios offering a framework for decision making.

The confluence of factors related to scientific and technological evolution can explain it. Satellite technology has allowed a remarkable increase in data availability and accuracy. Besides, computer science has made possible the evolution of increasingly complex, consistent and capable of treating large databases models, both qualitatively and quantitatively. The results have been more reliable day after day, permitting scenarios’ reproduction and discovering trends for more informed decision making. Proof of this advance is a recent article written by Tellman et al., (2021). The manuscript presents available data from flooded areas between 2000-2018 (with a resolution of 250m), identifying an affected area of 2.23 million km2 and 255 to 290 million people directly impacted by these events worldwide. It represents an increase of 58 to 86 million people between 2000 and 2015, number ten times higher than est...

From the cooperatives’ activities, there is direct contribution to a cluster of SDGs, namely, SDG 5 (gender), SDG 6 (water and sanitation), SDG 7 (sustainable energy), SDG 11 (sustainable settlements), SDG 12 (ensuring sustainable consumption and production), SDG 13 (climate action), SDG 14 (life in oceans), SDG 15 (life on land), and SDG 17 (partnerships). The main methods of data generation were interviews and field observations. It emerged that the significant contributions of community-based waste recycling cooperatives to scaling up SDG 12 implementation resulted in many direct and strong linkages with other SDGs as highlighted herein. This further opens up opportunities for policy cohesion and integration that may optimize positive externalities. To this end, we recommend that more of such activities be initiated in Brazil and, where possible, in other areas of the world leading to 2030.

Tal fenomeno atinge as areas dos municipios com diferentes intensidades e desse fato depende a sensivel biodiversidade e a sociodiversidade pantaneira. Todavia, as politicas publicas regionalizam os municipios de forma homogenea. Diante dessa problematica, a pesquisa teve como objetivo analisar seis programas (1970-2018) e descrever cenarios por meio de duas legislacoes direcionadas ao Bioma Pantanal. Adotou-se como metodologia a analise do conteudo nas categorias: criterios de regionalizacao; grau de interferencia do pulso de inundacao no agrupamento dos municipios; acoes desenvolvidas pelas politicas e os impactos socioambientais; inclusao da sociodiversidade na elaboracao das acoes.

Forest fragmentation and deforestation are subjects of great concern in tropical regions, namely ... more Forest fragmentation and deforestation are subjects of great concern in tropical regions, namely in South America and Africa, contributing to a rapid loss of tropical forest area and with serious implications for ecosystem functioning and biodiversity conservation. Despite the decrease in deforestation rates in recent years, the Brazilian Amazon, with the largest continuous region of tropical forest in the world, has suffered the greatest recorded losses, which have been contributing to continuous habitat fragmentation and a reduction in the territory occupied by Amerindian populations. In an attempt to preserve the remaining habitats and forests, Brazil has been adopting land conservation policies, including the implementation of protected areas. Protected areas (PAs) possess the potential to significantly reduce habitat fragmentation by conserving large, contiguous areas of land. In order to examine how effective PAs are at conserving forest area in the Brazilian Legal Amazon, patterns of deforestation are analyzed and compared, inside and outside the PAs, through landscape metrics calculated using the Patch Analyst and V-LATE extensions of a Geographic Information System. Two different sources (the Hansen Global Forest Change Dataset and the Brazilian National Institute for Space Research's (INPE) PRODES project) of annual forest cover-loss data derived from satellite imagery at medium-to-high spatial and temporal resolutions are compared at two-yearly intervals across 2002-2016. Additionally, fragmentation levels associated with deforestation patterns are assessed through an index modeled using a set of uncorrelated landscape metrics, and the associated change factors and trend are discussed. Results show that there is greater fragmentation in some PAs located in Mato Grosso and Pará States, especially those near the "arc of deforestation", and that Yanomami Indigenous Lands (YIL) are tending towards more fragmentation. Although some PAs are in a critical condition, findings show they all actively contribute to improved conservation of the native ecosystem and, in conjunction with sustainable management policies, will continue to help reduce or avoid forest fragmentation and degradation processes.

É nesse contexto, reforçado por ameaça de redução nas verbas destinadas à pesquisa científica, que entra em cena um movimento voltado para a valorização da Ciência, defendendo-se o uso de evidências científicas no processo de tomada de decisão em todos os níveis de governo: a marcha pela ciência, convocada para o dia 22 de abril, quando o número anterior da revista Sustentabilidade em Debate já estava em fase de finalização.

These signatures were based on metrics that informed different patterns for each landscape type, which allowed the behavior of the landscape to be visually analyzed. The signature system was applied through a landscape classification developed through fieldwork to gather data on socioenvironmental categories combined with remote sensing data. The study site was the border region between Brazil and French Guiana. The results of this work showed that in situ landscape classification techniques can be supported by the analysis of quantitative metrics of landscape analysis, reinforcing the need for integrative and systemic studies in landscape geography.

Até que ponto o conhecimento tradicional de observação dos sinais da natureza favorece a organização das atividades agropecuárias e, em caso de condições adversas, torna-se um instrumento de adaptação? Resulta de pesquisa de campo realizada no Seridó Potiguar (RN) e toma como referência a revisão de literatura sobre percepção e etnoclimatologia, cotejando as atividades econômicas praticadas pelos agricultores familiares e a caracterização climática por meio de análise de agrupamentos homogêneos na região de estudo. Ao fim, apresenta recomendações para políticas públicas, diante do contexto analisado.

Historicamente, a ampliação da consciência do direito à escola nas últimas décadas está totalmente associada à luta pela melhoria das condições básicas de sobrevivência, ou seja, as condições sociais, econômicas e políticas. O que queremos ressaltar é que não se pode isolar a escola do contexto histórico e dos movimentos sociais, sob pena de proceder a uma análise parcial e fragmentada do processo educacional. O fortalecimento da escola enquanto um ente a serviço dos interesses populares passa justamente pela luta para abertura dos muros da escola à comunidade. Propomos pensar nos indivíduos na sua integralidade levando em consideração os processos de humanização. Para tanto, parcerias entre a educação formal e educação não-formal representam um caminho fértil para promover o desenvolvimento humano. Assim é necessário que se faça da escola um espaço de transformação e que as escolas funcionem como centros de referência nas suas regiões de influência.
