Title A name given to the resource Actividad solar y su asociación con el régimen de lluvias en El Salvador Creator An entity primarily responsible for making the resource Angel Sol-Sanchez, Prof. Dr., Pablo Sierra-Figueredo, Ing., Edgar Antonio Marinero-Orantes, Prof. Dr. Description An account of the resource Numerosas publicaciones muestran evidencias sobre los posibles vínculos entre la variabilidad de la Actividad Solar y el clima terrestre, manifestado en acumulados de precipitación pluvial, presión atmosférica y temperatura, entre otros parámetros para diferentes latitudes geográficas y épocas. La variabilidad del clima, incluyendo la tendencia observada, es conocido que tiene una componente dependiente del calentamiento global de origen antropogénico en la era moderna, lo cual al parecer, está modulado por la acción externa del Clima Espacial, el que imprime fluctuaciones ―desde afuera‖, imponiendo ritmos que se superponen a los endógenos, lo que se evidencia en los registros multianuales de las variables climáticas. Se plantea la hipótesis de asociación entre los agentes cósmicos y el clima del planeta. Con este trabajo elaborado durante los años 2016 y 2017, resultado del análisis estadístico clásico de registros de acumulados pluviales de 8 estaciones brindados por la Dirección General del Observatorio Ambiental, Ministerio del Medio Ambiente y Recursos Naturales de El Salvador (DGOA-MARN), hemos querido, como objetivo, mostrar su comportamiento para un período de 45 años (1971-2015) y analizar su posible asociación con la variabilidad de la Actividad Solar y Geomagnética en la región de Centroamérica, para cuya región no hemos encontrado publicaciones originales anteriores donde se acometa dicho análisis. Se muestran los resultados estadísticos clásicos de las series de tiempo obtenidas, para cada una de las Estaciones y en su conjunto, ofreciendo las conclusiones positivas de los autores en cuanto a la validez de la hipótesis de asociación.

Title A name given to the resource Uma tipologia dos estabelecimentos agropecuários do Brasil a partir do censo de 2006 Creator An entity primarily responsible for making the resource Angela Antonia Kageyama, Sonia Maria Pessoa Pereia Bergamasco, Julieta Teresa Aier de Oliveira Description An account of the resource Baseando-se na composição da mão de obra utilizada, medida a partir do número de pessoas e do tempo de trabalho no ano, os estabelecimentos agropecuários foram agrupados em quatro categorias: assentado, exclusivamente familiar, familiar com contratado, não familiar. Os estabelecimentos de 'assentados' são em quase sua totalidade estabelecimentos familiares; os 'exclusivamente familiares' são estabelecimentos conduzidos pelo produtor exclusivamente com mão de obra familiar (pessoas com laço de parentesco com o produtor, sem pessoal contratado); os 'familiares com contratados' utilizam pessoas da família e pessoal contratado, porém a mão de obra familiar supera a dos contratados; os estabelecimentos 'não familiares' incluem os que operam somente com trabalho contratado e aqueles em que a força de trabalho contratada supera a dos membros da família do produtor. Foram analisadas as características de área, valor da produção, produtividade e fontes de receitas. Os estabelecimentos familiares são predominantes (90%) e abrigam 80% das pessoas ocupadas na agricultura, mas geram somente 50% do valor produzido. A concentração fundiária dentro das categorias familiares é tão elevada quanto nos estabelecimentos não familiares. No Brasil, apenas 16% da desigualdade da distribuição da terra se deve à desigualdade entre as categorias analisadas; os 84% restantes devem-se à desigualdade dentro dos grupos.A classification of farms in four types is proposed, according to the composition of the labour force employed: exclusively family farm; land reform settlement ('assentado'); family farm with hired labour; non-family farm. Exclusively family farms are run by the owner and employ exclusively family labour; land reform settlements are also mostly family-run units; mixed family farms are run by the owner and employ predominantly family labour, complemented by hired labour; non-family farms depend mostly on hired labour, with or without the help of the owner's family. Aspects such as area, gross production value, productivity and revenues are analysed. One of the main results is that the family units are largely predominant in number (90% of the total) and employ 80% of the labour force in the agricultural sector, although they contribute with only 50% of the gross production, in virtue of lower productivity. Inequality in land distribution within the groups is extremely high, even among family farms. In Brazil, only 16% of the total inequality of land distribution is due to the inequality between the four categories of farms, while 84% originate from the inequality within groups.

Title A name given to the resource TROPOMI NO2 Tropospheric Column Data: Regridding to 1 km Grid-Resolution and Assessment of their Consistency with in Situ Surface Observations Creator An entity primarily responsible for making the resource Angela Cersosimo, Carmine Serio, Guido Masiello Description An account of the resource This work presents a regridding procedure applied to the nitrogen dioxide (NO2) tropospheric column data, derived from the Copernicus Sentinel 5 Precursor Tropospheric Monitoring Instrument (S5P/TROPOMI). The regridding has been performed to provide a better comparison with punctual surface observations. It will be demonstrated that TROPOMI NO2 tropospheric column data show improved consistency with in situ surface measurements once the satellite retrievals are scaled to 1 km spatial sampling. A geostatistical technique, i.e., the ordinary kriging, has been applied to improve the spatial distribution of Level 2 TROPOMI NO2 data, which is originally sparse and uneven because of gaps introduced by clouds, to a final spatial, regular, sampling of 1 km ´ 1 km. The analysis has been performed for two study areas, one in the North and the other in the South of Italy, and for May 2018-April 2020, which also covers the period January 2020-April 2020 of COVID-19 diffusion over the Po Valley. The higher spatial sampling NO2 dataset indicated as Level 3 data, allowed us to explore spatial and seasonal data variability, obtaining better information on NO2 sources. In this respect, it will be shown that NO2 concentrations in March 2020 have likely decreased as a consequence of the lockdown because of COVID-19, although the far warmest winter season ever recorded over Europe in 2020 has favored a general NO2 decrease in comparison to the 2019 winter. Moreover, the comparison between NO2 concentrations related to weekdays and weekend days allowed us to show the strong correlation of NO2 emissions with traffic and industrial activities. To assess the quality and capability of TROPOMI NO2 observations, we have studied their relationship and correlation with in situ NO2 concentrations measured at air quality monitoring stations. We have found that the correlation increases when we pass from Level 2 to Level 3 data, showing the importance of regridding the satellite data. In particular, correlation coefficients of Level 3 data, which range between 0.50–0.90 have been found with higher correlation applying to urban, polluted locations and/or cities.

Tesche Description An account of the resource Este estudo se propôs a promover atitudes ambientais favoráveis em adolescentes através de debates de dilemas com conteúdo ecológico. Os dilemas foram elaborados com base na teoria de julgamento moral de Kohlberg e na técnica de discussão de dilemas morais em grupo, criada por Blatt e Kohlberg. Dezesseis estudantes do primeiro ano do segundo grau de uma escola pública de Porto Alegre participaram do estudo, tendo sido aplicado nesses estudantes, como pré-teste e pós-teste, um questionário de dez itens sobre atitudes em relação à ecologia. As respostas dos participantes foram avaliadas numa escala de zero a dois pontos, indicando o grau de maturidade de atitudes em relação ao ambiente. O grau de participação nas discussões de dilemas também foi analisado. A análise dos dados indica que a técnica foi eficaz somente para os alunos considerados participativos nas discussões.This research study had the purpose of promoting favorable attitudes toward the environment in adolescents through debates of dilemmas with ecological content. The dilemmas were elaborated with basis on Kohlberg's theory of moral judgment and on Blatt and Kohlberg's group discussion technique. Sixteen students from the first year of high-school from a public school in Porto Alegre (Brazil), participated in the research study. These students were administred a ten-item questionnaire about attitudes regarding ecology, as pre-test and post-test. The participants responses were rated in a zero to two points scale, indicating the degree of maturity of attitudes regarding the environment. The degree of participation in the discussions was also analyzed. The analysis of data reveals that the technique worked only for those students considered high in participation in the discussions.

Title A name given to the resource Energy, water vapor and carbon fluxes in Andean agroecosystems: conceptualization and methodological standardization Creator An entity primarily responsible for making the resource Angela María Castaño Marín, Nestor Miguel Riaño Herrera, Andrés Javier Peña Quiñones, Víctor Hugo Ramirez Builes, Arley Valencia Salazar, Apolinar Figueroa Casas, Gerardo Antonio Góez Vinasco Description An account of the resource This paper presents the conceptualization, methodological adjustment and experimental application of the micrometeorological technique eddy covariance - EC, to measure energy, water vapor and CO2 fluxes in two coffee agroecosystems: the first under full sunlight, and the second under shade, both with equatorial Andean hillslope conditions. With a footprint and fetch calculation, the required distance from the edge of the field in the prevailing wind direction to the EC tower is three times higher under shade than full sun. The shaded agroecosystem reached maximum average carbon fixation rates of 21.26 ± 2.469 μmolCO2.m-2s-1 ( = 0.05) (61% higher than under 100% sunlight) which gives a high carbon sink capacity to the association of coffee plants with shading Pigeon peas (Cajanus cajan L). The average evapotranspiration rate was 2.33 ± 0.0102 mm.d-1 ( = 0.05) and 2.08 ± 0.00732 mm.d-1 under shade and 100% sunlight, respectively. The proportion of net radiation that reached the soil was 2% under shade and 4% under 100% sunlight. Likewise, the soil energy loss during the night was lower under shade, indicating less day-night temperature range in the latter agroecosystem. The methodological adjustment and the results of this first work using EC in Colombian coffee plantations, contribute to the development of reliable research regarding gas and energy exchanges between the atmosphere and ecosystems in conditions of the equatorial Andean hillslope.

Por este prisma, a agricultura orgânica busca otimizar a utilização de recursos naturais na propriedade e evitar desperdícios pela adoção de práticas conservacionistas. Dessa forma, dois experimentos de consórcios de alface-cenoura, submetidos a 0 t ha-1, 12 t ha-1, 24 t ha-1 e 48 t ha-1 de composto orgânico, foram realizados em 2000, no município de Seropédica, RJ, com o objetivo de monitorar os teores de P, K, Ca, Mg e pH, em Argissolo Vermelho-Amarelo. O delineamento experimental foi em blocos ao acaso, com cinco repetições. Os tratamentos foram combinados em esquema de parcela subdividida no tempo, sendo as doses de composto orgânico as parcelas, e as coletas de solo as subparcelas. As coletas de solo foram realizadas na profundidade de 0-10 cm, 15 dias antes da instalação (DAI), 0, 6, 57 e 101 dias após plantio (DAP), no primeiro experimento, e 8 DAI, 1, 6, 60 e 116 DAP, para o segundo experimento. Quando submetido a doses crescentes de composto orgânico, independentemente do composto, P e K responderam às doses, enquanto Ca e Mg foram influenciados pela qualidade do composto. O período de máxima disponibilidade de P, K, Ca e Mg às plantas foi aos 6 DAP, em ambos os experimentos. As maiores correlações foram obtidas em P x Ca, P x Mg e K x Ca e apresentaram variação com a qualidade do composto orgânico. PALAVRAS-CHAVE: Dinâmica de nutrientes; fósforo; potássio; adubação orgânica. Indiscriminate use of fertilizers is responsible for problems as leaching and surface runoff, making more negative the energy balance in agroecosystems. The organic soil management using biological practices avoids waste and optimizes the exploration of natural resources. Two experiments, with intercropped lettuce and carrot and fertilized with organic compost (0 t ha-1, 12 t ha-1, 24 t ha-1, and 48 t ha-1), were conducted in Seropédica, Rio de Janeiro State, Brazil, during the year 2000, to observe P, K, Ca, and Mg levels, and pH in an Ultisol. Twenty treatments were evaluated using a complete randomized block design, with four replications. The treatments were combined as plots split in time, using doses of organic compost as main plots, and five collecting times as split plots. Soil was sampled at 0-10 cm, before and during the experimental period: 15 days before installation (DBI), 0, 6, 57, and 101 days after planting (DAP), in the first experiment, and 8 DBI, 1, 6, 60, and 116 DAP, in the second. P and K reflected the compost doses, independently of compost type, while Ca and Mg were dependent on compost quality. The period of maximum availability of P, K, Ca, and Mg occurred at 6 DAP, for both experiments. Highest correlations occurred between P and Ca, P and Mg, and K and Ca, which were associated with organic compost quality. KEY-WORDS: Nutrients dynamics; phosphorus; potassium; organic manure.
