ABSTRACT

Euterpe edulis is an endangered palm species that provides the most important non-timber forest product exploited in its natural habitat, the Brazilian Atlantic Forest hotspot1,4. From 1991 to 2017, pasturelands, agriculture, and monoculture of tree plantations were responsible for 97% of Atlantic Forest deforested areas in Brazil and Santa Catarina was one of the Brazilian states with the greatest loss of forest area14. In the last decade, E. edulis fruits reached their highest commercial value, producing the southeastern equivalent of Amazonian ''açai'' (Euterpe oleracea)5,7,8. As a shade-tolerant species, E. edulis adapts very well to agroforestry systems8,10. To evaluate potential areas for cultivation of E. edulis through agroforestry systems, we developed and applied a spatial model for mapping suitable areas. To accomplish this, we analyzed multisource biophysical data and E. edulis distribution data from the Forest Inventory of Santa Catarina. We identified two areas with potential occurrence of the species, one in the domains of coastal Dense Ombrophilous Forest where the species is more common and another in the domains of inland Deciduous Seasonal Forest where its occurrence was suspected, but not proven, until 2021. Today, Deciduous Seasonal Forest is the most fragmented and impacted by agriculture. Our model, together with confirmed areas of occurrence, indicates that deciduous seasonal forest region should be prioritized for production and recovery of E. edulis through agroforestry systems.

ABSTRACT

The Agricultural Research Company of Santa Catarina State (Epagri) is one of the main references in agricultural research. The objective of this paper was to make a bibliometric analysis of the scientific publications generated by Epagri, whose metadata are registered in the Epagri System of Technical and Scientific Production (Seprotec). The metadata year of publication, title, keywords, and publication type were considered in analysis. Metadata were analyzed in the statistical package R, using the UDPIPE library. From 1972 to October 2021, 15,841 publications were indexed in Seprotec, of which 67% as scientific publications. During the 70s and 80s, research focused on agronomic issues, seeking to increase crop productivity. From the 90s onwards, the environmental component gained relevance, addressing soil and water conservation aspects. Today, agricultural research in Santa Catarina is facing a new challenge, to make agricultural activity economically, socially and environmentally viable. Among the new research subjects, agroecology and regenerative agriculture stand out.


A Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri) é uma das principais referências em pesquisa agropecuária no estado. O objetivo desse trabalho foi fazer uma análise bibliométrica das publicações científicas geradas pela Epagri, cujos metadados estão cadastradas no Sistema Epagri de Produção Técnico-Científica (Seprotec). Foram utilizados os seguintes metadados: ano de publicação, título, palavras-chave e tipo de publicação. Os metadados foram analisados no pacote estatístico R, utilizando a biblioteca UDPIPE. De 1972 até outubro de 2021 havia 15.841 publicações no Seprotec, das quais 67% são publicações científicas. Durante as décadas de 1970 e 1980 a pesquisa focou nos aspectos agronômicos, buscando o aumento de produtividade das culturas. A partir da década de 1990 a componente ambiental ganhou relevância, abordando aspectos de conservação de solos e da água. Hoje a pesquisa agropecuária em Santa Catarina está diante de um novo desafio, que é tornar a atividade agropecuária do estado viável econômica, social e ambientalmente. Dentre as novas frentes de pesquisa destacam-se a agroecologia e a agricultura regenerativa.

ABSTRACT

This article describes a methodology for optimising predictive models for concentrations of faecal indicator organisms (FIOs) in coastal areas based on geographic and meteorological characteristics of upstream catchments. Concentrations of FIOs in mussels and water sampled from 50 sites in the south of Brazil from 2012 to 2013 were used to develop models to separately predict the spatial and temporal variations of FIOs. The geographical parameters used in predictive models for the spatial variation of FIOs were human population, urban area, percentage of impervious cover and total catchment area. The R2 of models representing catchments located within 3.1 km from the monitoring points was up to 150% higher than that for the nearest catchment. The temporal variation of FIOs was modelled considering the combined effect of meteorological parameters and different time windows. The explained variance in models based on rainfall and solar radiation increased up to 155% and 160%, respectively.

ABSTRACT

The objective of this research was to perform the agronomic and edaphoclimatic characterization of vineyards and to determine cultivation trends for the main varieties employed in the production of high altitude fine wines in Santa Catarina State, Brazil. High altitude vineyards were considered those vineyards located 900 m above sea level and vineyards belonging to members of the Santa Catarina Association of Altitude Fine Wines located below 900 m altitude. To assess cultivation trends, the vineyards were geo-referenced, following the Embrapa Uva e Vinho guidelines. To perform the edaphoclimatic characterization, the vineyard polygons were overlaid with physiographic, climatic and soil maps in a Geographic Information System. The characterization of the high altitude vineyards was based on planted area. The varieties with greatest areas were Cabernet Sauvignon (37.9%), Merlot (14.5%) Chardonnay (8.0%) and Sauvignon Blanc (7.5%). From 2009 to 2013 vineyards with C. Sauvignon were replaced for white varieties and for Pinot Noir, especially in altitudes over 1,100 m. A trend in the use of white varieties and Pinot Noir in new vineyards was identified, but the main trend was the increase of experimental areas, with additional 60 varieties of red and white grapes. In relation to physiography, the norm of the Acavitis requires that the vineyards of their associates be located above [...](AU)

Para avaliar as tendências de cultivo foi realizado um cadastro georreferenciado, seguindo as normas da Embrapa Uva e Vinho. Para realizar a caracterização edafoclimática, as áreas dos vinhedos foram cruzadas com mapas fisiográficos, climáticos e pedológicos em um Sistema de Informações Geográficas. A caracterização dos vinhedos de elevada altitude foi realizada com base na área plantada. As variedades com maior área foram Cabernet Sauvignon (37,9%), Merlot (14,5%), Chardonnay (8,0%) e Sauvignon Blanc (7,5%). De 2009 a 2013 houve substituição de C.

Houve uma tendência no uso de variedades brancas e Pinot Noir em vinhedos novos, mas a principal tendência observada foi no crescimento de áreas experimentais, com outras 60 variedades tintas e brancas. Em relação à fisiografia, a [...](AU)
