Acrocomia spp., a genus of wild-growing palms in the neotropics, is rapidly gaining interest as a promising multipurpose crop. Diverse products can be derived from various components of the palm, the oils being of highest interest. Acrocomia shows similar oil yield and fatty acid composition to the African oil palm (Elaeis guineensis). It is, however, able to cope with a wider range of environmental conditions, including temporary water scarcity and lower temperatures, thus potentially a more sustainable alternative to its tropical counterpart. Acrocomia’s research history is recent compared to other traditional crops and thus knowledge gaps, uncertainty, and challenges need to be addressed. This review attempts to assess the acrocomia’s preparedness for cultivation by highlighting the state-of-the-art in research and identifying research gaps. Based on a systematic literature search following a value web approach, it (a) provides a comprehensive overview of research topics, (b) shows the development of publication activities over time and the drivers of this development, and (c) compiles main findings to assess the acrocomia’s preparedness for commercial cultivation. Our results confirm its multipurpose characteristic as a potential feedstock for manifold sectors. Research has continued to increase over the last decade, especially on A. aculeata and is driven by the interest in bioenergy. Increasing knowledge on botany has contributed to understanding the genetic diversity and genus-specific biology. This has enabled applied research on seed germination and propagation toward domestication and initial plantation activities, mostly in Brazil. Main research gaps are associated with genotype–environment interaction, planting material, crop management, and sustainable cropping systems. Overall, we conclude that acrocomia is at an early phase of development as an alternative and multipurpose crop and its up-scaling requires the integration of sustainability strategies tailored to location-based social-ecological conditions.
RESUMOO estado de Mato Grosso vem apresentando expressivas taxas de crescimento econômico nos últimos anos, de modo que a utilização da matriz insumo-produto, como estratégia de política econômica, representaria não somente a busca da manutenção desse crescimento econômico, mas a preocupação de que o mesmo se traduza em desenvolvimento sócio-econômico. Assim, o presente artigo tem como objetivo geral a apresentação das notas metodológicas de construção da matriz insumo-produto para o Mato Grosso, acompanhadas de uma análise geral da estrutura produtiva da economia do estado. Os principais métodos de análise utilizados no estudo foram os índices de ligações inter-setoriais, bem como os multiplicadores de emprego, renda e produção. Os resultados empíricos confirmaram a importância dos setores primários em termos de suas relações comerciais com as demais atividades, como forma de estimular o aquecimento da economia. Finalmente, através da análise dos multiplicadores, foi possível identificar a importância de diversos setores relacionados ao agronegócio, no que diz respeito às suas capacidades de geração direta e indireta de emprego e renda na economia. Palavras-chave: Matriz insumo-produto, indicadores econômicos, Mato Grosso. ABSTRACTThestate of Mato Grosso has been showing remarkable rates of economicgrowth in recent years. Hence, the use of input-output analysis as aeconomic policy strategy would represent not only the search formantaining such economic growth but also the concern that the thisprocess can be converted into socioeconomic development. Thus, thispaper aims to show the general methodological notes for theconstruction of input-output matrix for Matto Grosso followed by anoverview of the State's economy productive structure. The
Background: Brazil is the world's largest sugarcane producer, and its production is concentrated in south-central and northeast regions, particularly in the state of São Paulo. The land use change, principally from the increasing sugarcane production, may reflect in the farmland prices. The aim of this study is to evaluate the extent to which agricultural land prices in São Paulo are determined by variations in cultivation and prices of three products that represent a significant share of agriculture in the state: sugarcane, soy and corn, in a low-inflation environment. Methods:Analysis is based on data from the Rural Development Offices (EDR) from 1997 to 2013. A simple panel data model is constructed with land price as the dependent variable, subdivided, according to the definition of the São Paulo State Institute of Agricultural Economics, into first-and second-class croplands. Cultivation area, unit price of the products, and lease value are explanatory variables, according to each crop. Inflation and the overall production value of São Paulo's farming production, excluding the production values of corn, soy and sugarcane, also serve as explanatory variables. Results:The results show that in São Paulo, although part of the land price variation can be explained by the variables associated with their productive use, the impact of inflation indicates that land's function in storing value contributes significantly to land prices. Conclusions:The most prominent conclusion is that expansion in sugarcane cultivation has led to higher farmland prices in the state of São Paulo.
During the 2000s and 2010s, the growth in sugar and ethanol production stimulated the expansion of sugarcane in new regions of Brazil, reducing the concentration in the state of São Paulo. This paper aims to investigate whether the rise in sugarcane production in peripheral areas has led to the growth of knowledge capabilities. In order to consider regional asymmetries, the article uses the differentiated knowledge base (DKB) approach in association with regional innovation systems (RIS) and core-periphery relations. Data on formal employment and scientific research on the Central-South region are analyzed from 2003 to 2017. The results show that there are limits to the diffusion of sugarcane knowledge as an important part of knowledge production remains concentrated in the regions of early growth in São Paulo.
Introdução: O estudo examina o crescimento da produção científica brasileira no período 1990 – 2017, com base em amostra composta por aproximadamente 5,8 milhões de artigos científicos indexados à plataforma Lattes. Foram identificados pontos de mudança na taxa de crescimento exponencial da produção científica em oito grandes áreas do conhecimento. Tais pontos, estimados através de um modelo de crescimento exponencial, segmentam a produção científica em períodos marcados por taxas constantes de crescimento. A periodização dos resultados facilita a contextualização da produção científica frente às políticas científicas implementadas nas últimas décadas. Objetivo: produzir indicadores para insumos de discussões sobre o desempenho recente da ciência nacional e contribuir com análises que têm como base de dados informações disponibilizadas na Plataforma Lattes. Metodologia: destaca a Plataforma Lattes como banco de dados essencial ao entendimento da ciência brasileira e, a partir da coleta de dados, aplica modelos de regressão segmentada que compreendem as transformações quantitativas da atividade científica ao longo do período analisado. Resultados: Constataram que o total da produção científica brasileira cresceu a uma taxa exponencial anual de 6,61 % entre os anos de 1990 a 2017, porém observando uma desaceleração do crescimento da produção científica nas áreas avaliadas na primeira metade da década de 2000. As áreas de Ciências da Saúde e Biológicas registraram as menores taxas de crescimento. Conclusões: reforçam a relevância da Plataforma Lattes nas avaliações da produção científica nacional, e apontam novos caminhos e indagações para pesquisas futuras que poderão contribuir à compreensão do status quo do fazer científico brasileiro.
