“…Despites its fragmentation, it is one of the most biodiverse biomes in the world (Mittermeier et al, 1998) that harbors biodiversity hotspots (Myers et al, 2000). It has a history of intense and damaging transformation since the 15th century due to different economic cycles (timber extraction, sugarcane and coffee plantations until the end of the 19th century), followed by urbanization and industrialization processes, and more recently, the expansion of extensive livestock (Dean, 1996;Young, 2006;Campos, 2011;Cabral, 2014;Maioli et al, 2020). Due to its environmental and socioeconomic importance and high degree of fragmentation, restoration is a priority for the Atlantic forest (Ribeiro et al, 2009;Scarano and Ceotto, 2015), especially in private lands, where land use decisions play a key role in achieving national (e.g., PLANAVEG, BRASIL, 2017) and international conservation and restoration goals (e.g., Crouzeilles et al, 2019;Strassburg et al, 2019;Bonn Challenge, 2020).…”

Local Perception in Forest Landscape Restoration Planning: A Case Study From the Brazilian Atlantic Forest

et al. 2021

Understanding local stakeholders' perception and their relation with the landscape and its natural resources is an important step for successfully implementing Forest Landscape Restoration (FLR). Here, we present a case study on FLR in the context of a global biodiversity hotspot—the Brazilian Atlantic Forest, using a participatory approach to include local stakeholders' knowledge and perception of the landscape into project planning. We analyzed the land use and cover, and organized a workshop with focus group methodology associated with maps and other visual representations to assess local perceptions of economic activities, production chains and their impacts on the landscape and ecosystem services. The study area encompasses seven municipalities mainly covered by native vegetation and pastures. Despite pastureland being the prominent land use in the region, they are not engaged in associations, most do not live in the region, and few participated in the workshop. Most participants were small and medium-scale landowners involved in agricultural activities who demonstrated a detailed knowledge of the territory, a disposition toward combining conservation with production practices, and a positive perception regarding ecotourism, agroecological approaches, water, and soil conservation. The participatory approach proved effective to complement the initial assessment while revealing novel aspects of the landscape and the landowners, helping test our hypotheses and adjust the engaging narratives for future FLR activities planning in the region, including environmental law compliance. More studies associating social and natural science, including participatory methods and local communities' perception, are needed to fully comprehend the drivers of stakeholders' engagement. This case study provides useful insights for other researchers and practitioners to design more effective plans for future land management.

“…It is a crop with a important value in the world economy, responsible for most of the oil seed production (Wilson, 2008). The large consumption and the new genetic materials developed, to justify the widespread cultivation of soybean and enable their's consumption worldwide, especially in the United States, Brazil, Argentina and China (Campos, 2011;Nishinari et al, 2014, Rocha et al, 2018.…”

Soybean (Glycine max (L.) Merrill) is an agricultural crop with a large increase in production in the last three decades and is an essential component in the manufacture of animal and human food. Understanding the interactions between crop and other plant species used as green manure that can improve yield and so reduce environmental damage. Forages can release secondary metabolites in the environment that influence in a beneficial or harmful way to other plants, characterizing the allelopathy process. The Níger (Guizotia abyssinica Cass.) is used in agricultural systems because it releases allelochemicals, especially flavonoids. Therefore, this study is aimed to evaluate the allelopathic effects of the Niger straw on the germination and initial growth of soybean seedlings. The treatments consisted of aqueous extracts of niger stems, leaves and roots in different concentrations (0; 25; 50; 75 and 100%). For each treatment, five replications were performed, each composed by a 25 seeds distributed in gearbox kept in incubator chamber for 7 days at 25ºC and 12 hours photo period. The experimental design was completely randomized and the data were evaluated by analysis of variance and the means of treatments compared by Tukey’s test at 5% significance. The results show a reduction in germination and initial growth of soybean seedlings submitted to aqueous extract of niger stem and roots. In contrast, the aqueous extract of the Niger leaves increased the length of soybean seedlings. The allelopathic effects of the Niger probably occur due to the presence of flavonoids in the tissues of this plant species.

“…O Estado de Mato Grosso no contexto nacional tem expressiva contribuição nos resultados obtidos pelas cadeias produtivas de grãos, como cita o Instituto Mato-grossense de Economia Agropecuária (IMEA, 2012). A agricultura mato-grossense ganhou espaço após os anos de 1980, pela expansão da fronteira agrícola com a vinda dos agricultores da região Sul do país que trouxeram técnicas de produção (CAMPOS, 2011). A colonização foi possível diante do baixo valor das terras, das linhas especiais de crédito criadas pelo governo e as condições climáticas de relevo, isso fez com que os produtores se deslocassem para o Estado de Mato Grosso (BERNARDES, 1997).…”

RESUMO: O processo de planejamento da estratégia de produção compreende certos níveis de planejamento. De ordem macro para micro tem-se em primeiro plano a estratégia corporativa; dela faz parte a estratégia competitiva que abrange as prioridades competitivas. A partir das prioridades competitivas, juntamente às decisões estruturais e infraestruturais, forma-se a estratégia de produção. Foi com foco nesse nível de decisão que o estudo se desenvolveu tendo como objeto produtores de soja do município de Campo Novo do Parecis-MT. Para isso foi realizada pesquisa de campo com aplicação de questionários aos produtores rurais acerca da relevância das decisões estruturais e infraestruturais para o planejamento de safra. No estudo buscou-se: a) identificar o perfil das propriedades rurais b) verificar quais são as decisões adotadas pelos produtores e c) elencar os tipos de decisões considerando as decisões estruturais e as decisões infraestruturais para os produtores de soja. Os resultados encontrados evidenciam que todos os agricultores, em seu processo decisório da função produção, levam em conta os fatores estruturais e infraestruturais, sendo possível verificar que as decisões quanto às tecnologias são as mais relevantes nos fatores estruturais e, gestão da qualidade, planejamento e controle da produção e organização se destacam nas decisões infraestruturais. PALAVRAS-CHAVE:Produção agrícola; Decisões estruturais e infraestruturais; Gestão de operações. PRODUCTION STRATEGY: AN APPROACH ON OPERATIONABILIT Y IN SOYBEAN PLANTATIONSABSTRACT: Production strategy process comprises several levels of planning. Corporative strategy comprises competition strategy with competitive priorities
