    RESUMO. O combate à má alimentação em todas as suas formas, que também se expressa na epidemia da obesidade, é uma das prioridades da Agenda 2030 e dos Objetivos de Desenvolvimento Sustentável. Este artigo traz elementos sobre insegurança alimentar no Brasil, a partir de temas relativos ao crescimento populacional, mudanças climáticas, biodiversidade e sistemas alimentares tradicionais e regenerativos; trata também do papel dos movimentos sociais para a garantia do Direito Humano à Alimentação Adequada. O Grupo de Pesquisa em Nutrição e Pobreza, o Saúde Planetária Brasil, e o Centro de Inteligência Artificial (C4AI) - Eixo AgriBio, entendem que a retomada organizada e sistêmica das frentes apontadas neste artigo de posicionamento, pode constituir um caminho para a articulação entre pesquisa, serviço e políticas públicas na direção do combate à fome e às demais manifestações da má alimentação, enquanto problema complexo prioritário para a garantia do bem-estar social

    ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

    Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

    Building a Community-Based FAIR Metadata Schema for Brazilian Agriculture and Livestock Trading Data

    In this paper, we discuss how we are using metadata schemas and controlled vocabularies to improve interoperability between Brazilian agriculture and livestock trading data providers. A new metadata schema is being created based on a community-based approach. This method relies on knowledge from specialists to define a list of relevant metadata properties for a given domain. In the first step of the research, we extracted metadata from three datasets maintained by three Brazilian public institutions: the Center for Advanced Studies in Applied Economics (Cepea), the Institute of Applied Economic Research (Ipea), and The National Supply Company (Conab). The extracted metadata were the input to the definition of a list of 15 potential metadata properties that specialists are validating

This article presents reflections on food insecurity in Brazil, based on topics such as population growth, climate change, biodiversity and traditional and regenerative food systems; it also addresses the role of social initiatives to guarantee the Human Right to Adequate Food. The Nutrition and Poverty Research Group, Planetary Health - Brazil Group, and the Center for Artificial Intelligence (C4AI) - AgriBio Axis, assume that the organized and systemic resumption of the initiatives mentioned out in this position paper can contribute to the articulation between research, public policies and services, to combat all forms of malnutrition, as a complex and priority problem to ensure social welfare

    Estudos agrários: a complexidade do rural contemporâneo

    No full text
    Esta obra reúne trabalhos de pesquisadores de três universidades públicas brasileiras apresentados durante o I Colóquio de Pesquisas do Núcleo de Estudos Agrários da Unesp de Rio Claro, realizado em outubro de 2010. Organizada por Darlene Aparecida de Oliveira Ferreira, Enéas Rente Ferreira e Adriano Corrêa Maia, pretende compreender a realidade agrária brasileira contemporânea a partir de suas principais características, considerando o passado e o presente. A obra mostra que a diversidade espacial é umas das marcas importantes do sistema, com o mundo rural organizado distintamente em contextos regionais e atrelando culturas a áreas específicas. Por isso, os trabalhos tratam também de contextos espaciais historicamente construídos, dos quais emergem novos atores sociais ou se consolidam os detentores de estruturas passadas. As pesquisas identificam principalmente as características e as tendências da geografia agrária no Brasil do início do século XXI, os processos, como produção e migração, os usos modernos do espaço agrícola (como o turismo rural) e o papel atual das pequenas propriedades na agricultura brasileira

    Neste artigo abordamos alguns aspectos da natureza da sociedade escravista - na África e no Brasil - especialmente os significados da liberdade, cor, protesto entre os séculos XVII a XIX. Partimos de um diálogo crítico sobre as perspectivas de miscigenação, políticas de domínio e dinâmicas sociais nas sociedades escravistas e os desdobramentos para o seu funcionamento e mudança.<br>This article aims to focus some aspects concerning slave societies in Brazil and in Africa. In special, those related to the meanings of freedom, color, and protest between the eighteenth and nineteenth centuries. These issues are discussed from a critical dialogue on the perspectives about miscegenation, domination politics, social dynamics, and change in the slave societies
