    Given the scarcity of water resources that has been worsening over time and the high consumption of these resources by agribusiness, there is a need for studies that can manage such action in a sustainable way, providing food security for the present and future world population. Background: with the topic: What is the systemic view of automated models and techniques for determining or estimating transpiration, evaporation or evapotranspiration for plantations? Objectives: to identify in recent literature what researchers and scientists have disclosed about automation methods for supervision, with a focus on estimating evapotranspiration. identify methods, models and techniques for inferring evapotranspiration. Methods: A methodology based on exploratory theoretical testing with qualitative and quantitative characteristics through Systematic Review and Meta-Analysis of data. Results: Using specific software and methods, simulation studies with experimental data make it possible to calibrate efficient models to estimate evapotranspiration, but low-cost methods still have little adherence.Dada la escasez de recursos hídricos que se ha ido agravando con el tiempo y el alto consumo de estos recursos por parte de la agroindustria, se necesitan estudios que puedan gestionar dicha acción de manera sostenible, brindando seguridad alimentaria a la población mundial presente y futura. Antecedentes: con el tema: ¿Cuál es la visión sistémica de los modelos y técnicas automatizadas para determinar o estimar la transpiración, evaporación o evapotranspiración para plantaciones? Objetivos: Identificar en la literatura reciente lo que investigadores y científicos han publicado sobre métodos de automatización para riego, con enfoque en la estimación de la evapotranspiración. Identificar métodos, modelos y técnicas para inferir la evapotranspiración. Métodos: La metodología se basó en un ensayo teórico exploratorio con características cualitativas y cuantitativas mediante Revisión Sistemática y Metaanálisis de datos. Resultados: Utilizando software y métodos específicos, los estudios de simulación con datos experimentales permiten calibrar modelos eficientes para estimar la evapotranspiración, pero los métodos de bajo costo aún tienen poca adherencia.Tendo em vista a escassez de recursos hídricos que vem se agravando ao longo do tempo e o alto consumo desses recursos pelo agronegócio, há a necessidade de estudos que possam gerir tal ação de forma sustentável, proporcionando segurança alimentar para a população mundial presente e futura. Background: com o tema: Qual a visão sistêmica dos modelos e técnicas automatizadas para determinação ou estimativa de transpiração, evaporação ou evapotranspiração para plantações? Objetivos: Identificar na literatura recente o que pesquisadores e cientistas têm divulgado sobre métodos de automação para irrigação, com foco na estimativa da evapotranspiração. Identificar métodos, modelos e técnicas de inferência da evapotranspiração. Métodos: A metodologia baseou-se no ensaio teórico exploratório com características qualitativas e quantitativas por meio de Revisão Sistemática e Metanálise dos dados. Resultados: Com o uso de softwares e métodos específicos, estudos de simulação com dados experimentais permitem calibrar modelos eficientes para estimar a evapotranspiração, mas métodos de baixo custo ainda têm pouca aderência

    The importance and economic representativeness of the peanut production chain has grown exponentially in recent years, tending to gain more market share. Background: The study had as its theme the question: What is the economic, technological, social and environmental relevance of the peanut production chain for Brazil? Objective: Conduct a survey of information and data that allow inferring the economic, social and environmental importance of the peanut production chain for Brazil in the global scenario. Methods: The methodology applied was exploratory research "ad hoc" in exploratory theoretical essay of qualitative approach, and analytical descriptive in the report of the findings. Results: Exports grow on a logarithmic scale, in 2020 it had revenues of US$ 427.8 million. The sector generates 42 thousand jobs, and the culture makes it possible to meet social and environmental demands. Conclusions: The adoption of technologies and the improvement of production methods are essential for the continuous progress of the sector with the creation of jobs and the adhesion of new producers, with an increasingly sustainable production, with less environmental impact and reduction of fertilizer waste, with expansion of the productive capacity per planted bushel

    NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

    No full text
    Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used.
