RESUMO As atividades de recuperação insustentáveis (URAs) têm sido cada vez mais realizadas para responder à crescente procura global de alimentos, levando a graves repercussões nos ambientes terrestres. Um total de 120 amostras de solo representando 12 locais foram selecionadas aleatoriamente nos três tipos distintos de terra (PMFs, PALs e BHLs) a uma profundidade de 60 cm para avaliar os impactos das URAs na província de Nghe An Mountain, no Vietnã. A análise estatística dos parâmetros do solo foi realizada no software SPSS (versão 26.0) por meio de análise de variância unidirecional (ANOVA). As descobertas indicam diferenças distintas no tamanho das partículas do solo (SPS) entre os diferentes tipos de terreno (DLTs). Florestas virgens e mistas (PMFs) exibiram as menores proporções de areia, variando de 31,4 a 35,2%, enquanto colinas e terras nuas (BHLs) registraram as maiores proporções de areia, variando de 49,7 a 55,1%. Elevado densidade global (BD) foi observado em BHLs (1,36 ± 0,07 kg dm-3) e PMFs (0,89 ± 0,02 a 1,13 ± 0,03 kg dm-3) enquanto terras perenes e anuais (PALs) variaram de 1,17 ± 0,04 a 1,25 ± 0,08 kg dm-3. Os PMFs apresentaram baixos valores de porosidade total do solo (TSP) e teor de água do solo (SWC) com respectivas faixas de 32,97-36,18% e 4,72-6,15% enquanto PALs e BHLs exibiram valores elevados para TSP (39,25-43,19%; 43,97-49,62%). e SWC (7,39-10,07%; 9,98-12,74%). A capacidade de troca catiônica (CEC), Ca2+, K+ e Mg2+ registrou altos valores nos PALs em comparação aos PMFs e PALs, enquanto o conteúdo orgânico total (TOCs) detectou pouca variação entre os DLTs. No geral, as URAs aumentaram os efeitos adversos nas propriedades e funções do solo (SPFs) em toda a área de estudo.

ABSTRACT Unsustainable reclamation activities (URAs) have been increasingly conducted to respond to the rising global food demand, leading to severe repercussions on land environments. A total of 120 soil samples representing 12 sites were randomly selected in the three distinct land types (PMFs, PALs, and BHLs) to a depth of 60 cm. The impacts of URAs on soil properties and functions (SPFs) across the Nghe An mountainous province, Vietnam were assessed using the SPSS software (version 26.0) through a one-way analysis of variance (ANOVA). The findings indicated the distinct differences in soil particle size (SPS) among different land types (DLTs). Pristine and mixed forests (PMFs) exhibited the lowest sand ratios, ranging from 31.4 to 35.2%, while bare hills and lands (BHLs) recorded the highest sand ratios, ranging from 49.7 to 55.1%. High bulk density (BD) was observed in BHLs (1.36 ± 0.07 kg dm-3) and PMFs (0.89 ± 0.02 to 1.13 ± 0.03 kg dm-3) while perennial and annual lands (PALs) varied from 1.17 ± 0.04 to 1.25 ± 0.08 kg dm-3. PMFs showed low values for total soil porosity (TSP), and soil water content (SWC) with respective ranges of 32.97-36.18% and 4.72-6.15% while PALs and BHLs exhibited high values for TSP (39.25-43.19%; 43.97-49.62%), and SWC (7.39-10.07%; 9.98-12.74%). Cation exchange capacity (CEC), Ca2+, K+, and Mg2+ were recorded higher in PALs compared to PMFs and PALs while total organic contents (TOCs) detected little variation among DLTs. Overall, the URAs enhanced the adverse effects on the SPFs across the study area. (URAs demand environments 1 PMFs, (PMFs 6 cm (SPFs province version 26.0 260 26 0 oneway one way ANOVA. ANOVA .

RESUMO A ressonância magnética nuclear (RMN) é uma técnica de espectroscopia amplamente utilizada pelos químicos e físicos para determinar a estrutura química de moléculas que foi adaptada para gerar imagens, conhecidas como tomografia por imagem de ressonância magnética nuclear (IRM), amplamente utilizada em diagnóstico médico. A importância da RMN na química, física, medicina, materiais e agricultura tem sido reconhecida por vários Prémios Nobel de Física, 1952, Química, 1991 e 2002, e Medicina em 2003. Portanto, a RMN pode ser aplicada para obter: i) imagens do corpo humano, animais e materiais; ii) espectros de alta resolução para obtenção de informações estruturais e dinâmicas de produtos químicos, materiais etc.; e iii) obter informações quantitativas e qualitativas da composição química de alimentos, produtos agrícolas, utilizando relaxometria de baixa resolução. A IRM e a RMN de alta resolução tem sido aplicadas em produtos agroalimentares, principalmente na pesquisa, uma vez que normalmente dependem de instrumentos caros de grandes dimensões, o que restringe a sua utilização em aplicações rotineiras. Sensores de RMN que têm sido utilizados com mais frequência em produtos agroalimentares baseiam-se em instrumentos de baixa resolução ou de baixo campo ou domínio de tempo TD-NMR. Esses instrumentos de baixo custo tem sido utilizados para análises qualitativas e quantitativas de produtos agroalimentares, como sementes e grãos intactos, frutas intactas, carnes, óleos e alimentos processados. Neste artigo, é apresentada uma revisão das técnicas de RMN, seus principais aspectos da instrumentação, e discutidas algumas aplicações de TD-RMN e IRM na análise não invasiva de alimentos, sementes e outros produtos agrícolas.

ABSTRACT Nuclear magnetic resonance (NMR) is a spectroscopy technique widely used by chemists and physicists to determine the chemical structure of molecules that was adapted to generate imaging, known as nuclear magnetic resonance imaging (MRI), which is widely used in medical diagnosis. The importance of NMR in chemistry, physics, medicine, materials, and agriculture has been recognized with several Nobel Prizes in Physics, 1952, Chemistry, 1991 and 2002, and Medicine in 2003. Therefore, NMR can be applied to obtain: i) imaging of the human body, animal and materials; ii) high-resolution spectra to obtain structural and dynamical information of chemicals, materials etc.; and iii) quantitative and qualitative information of chemical composition of products such as food and agricultural products, using low-resolution relaxometry. High-resolution NMR and MRI have been applied in agri-food products, mostly as a research tool as they typically rely on expensive and bulk instruments, which restrict their uses in routine applications. The NMR sensors that have been more frequently used in agri-food products are based on low-resolution or low-field or time-domain NMR (TD-NMR) instruments. These low-cost instruments have been used for qualitative and quantitative analysis of agri-food products such as intact seeds and grains, intact fruits, meat, oils, and processed foods. In this paper, an overview of the NMR techniques and its main instrumentation aspects are presented, and some applications of TD-NMR and MRI in the non-invasive analysis of food, seeds, and others agricultural products are discussed.

RESUMO: O presente estudo avaliou a eficácia do uso de máscaras descartáveis na mitigação da propagação de Staphylococcus aureus durante o processo de corte de frango em um grande abatedouro de aves. Foi realizada a identificação de portadores de S. aureus e influência do tempo de uso de máscaras descartáveis. A contaminação em utensílios e equipamentos por S. aureus e produtos por aeróbios mesófilos foi determinada, com e sem uso de máscaras. A eficiência de diferentes máscaras comerciais foi avaliada contra S. aureus em condições simuladas. Os resultados revelaram que 36% dos trabalhadores das linhas de processamento no frigorífico eram portadores de S. aureus. Foi observado aumento na contagem de S. aureus em máscaras usadas pelos funcionários até 3 horas. A transferência de carga microbiana para utensílios foi potencializada na ausência da máscara e com o passar do tempo. Os filés de peito avaliados não apresentaram diferença na contagem de bactérias mesófilas com e sem o uso de máscaras pelos funcionários, por outro lado, os cortes de coxa e sobrecoxa, filé de coxa e sobrecoxa e asas apresentaram diferença significativa com contagens médias inferiores a 2,96 Log de UFC/g. Testes de condições simuladas demonstraram a eficácia das máscaras comerciais na retenção de microrganismos. A máscara teste utilizada pelo frigorífico mostrou-se ineficiente, permitindo a passagem de pulverizações contendo S. aureus, a 6, 15 e 25 cm, com 2,53, 1,74 e 0,66 Log UFC/placa, respectivamente. Essa máscara saturava, criando um efeito barreira que aumentava a contaminação na área de trabalho dos funcionários.

ABSTRACT: The present study evaluated the effectiveness of using disposable masks in mitigating the spread of Staphylococcus aureus during the chicken cutting process in a large poultry abattoir. The identification of carriers of S. aureus and the influence of the time of use of disposable masks was carried out. Contamination of utensils and equipment by S. aureus and products by mesophilic aerobes was determined, with and without the use of masks. The efficiency of different commercial masks was evaluated against S. aureus under simulated conditions. The results revealed that 36% of workers on processing lines at the abattoirs carried S. aureus. An increase in S. aureus counts was observed in masks worn by employees for up to 3 h. The transfer of microbial load to utensils was enhanced in the absence of the mask and over time. The breast fillets evaluated showed no difference in the count of mesophilic bacteria with and without the use of masks by employees, conversely, the cuts of thigh and drumstick, thigh fillet and drumstick and wings showed a significant difference with average counts lower than 2 .96 Log CFU/g. Tests under simulated conditions demonstrated the effectiveness of commercial masks in retaining microorganisms. The test mask used by the abattoirs proved to be inefficient, allowing the passage of sprays containing S. aureus, at 6, 15 and 25 cm, with 2.53, 1.74 and 0.66 Log CFU/plate, respectively. This mask saturated, creating a barrier effect that increased contamination in the employees’ work area.

ABSTRACT: This research aimed to understand the subject regarding the 2030 Agenda Sustainable Development Goals and food production through literature reviews covering the timespan from 2001 to 2021. Methodologically, this paper is framed as a literature review and uses the Scopus platform to get to the database, selecting 243 papers. The results pointed out that the United States presented the highest number of published documents (126). When it comes to the origin of affiliation, the universities located in the Netherlands (University of Wageningen) and Canada (University of Guelph) present together the highest number of published documents (24). Among the keywords, the most frequent are food safety, followed by the food supply, sustainability, and climate change. Finally, regarding the main subjects tackled during the analyzed time period, it was verified that the issues concerning public policies, land use, and food safety were discussed throughout the entire timespan. In turn, the most recent period, mainly covering the articles published from the year 2021 on, inserts into the discussion agenda the aspects of Covid-19, the pandemic, and its impacts, especially influenced by the setting experienced worldwide. At the same time, other subjects less discussed took the spotlight, also emerging from the Covid-19 pandemic, such as digital agriculture and digital technology, which began to have major relevance. At last, it is possible to infer that reaching sustainable development goals is even more challenging under a pandemic context experienced by all the countries from 2020 to the present day.

ABSTRACT The search for new technologies capable of providing benefits to healthy eating is a global goal. The consumption of foods rich in carotenoids can prevent serious health problems. Thus, the availability of foods high in carotenoids that are accessible to the majority of the population is essential. Lettuce (Lactuca sativa L.) is a suitable species for biofortification research based on genetic improvements. In this study, we aimed to select and obtain hybrid lettuce populations with high agronomic potential and biofortified carotenoid content. Ten lettuce lines registered in the “BG α Biofort” software were selected for hybridization. The crosses used to obtain the hybrids involved two strains rich in at least one of the pigments (chlorophyll and carotenoids), and 24 experimental hybrids were obtained. A total of 37 genotypes (strains, hybrids, and commercial cultivars) were evaluated using a randomized block design for agronomic variables and chlorophyll and carotenoid content. Hybrids 12 (UFU-189#3#4#1 × UFU MC BIOFORT 2) and 25 (UFU66#4#2 × UFU-189#3#4#1) had the potential to produce dual-purpose populations (yield and carotenoid biofortification). Hybrid 27 (UFU66#4#2 × UFU MC BIOFORT1) exhibited the best pigment balance. Thus, F2 hybrids 12, 25, and 27 should be obtained to produce new cultivars of biofortified red and green lettuce for curly, american, mini, and romaine lettuce segments. goal problems Thus essential Lactuca L.

Aliar alimentos com altos teores de carotenoides e acessíveis para a maior parte da população é fundamental. A alface (Lactuca sativa L.) se apresenta como uma espécie adequada para investir em pesquisas com biofortificação a partir de melhoramento genético. Assim, o objetivo com este estudo foi selecionar híbridos de alface visando à obtenção de populações com potencial agronômico e biofortificadas para carotenoides. Dez linhagens de alface cadastradas no Software “BG α Biofort” foram utilizadas nas hibridações. Os cruzamentos para obtenção dos híbridos foram planejados envolvendo duas linhagens ricas em pelo menos um dos pigmentos (clorofila e carotenoides) sendo obtidos 24 híbridos experimentais. Foram avaliados 37 genótipos (linhagens, híbridos e cultivares comercias) em delineamento em blocos casualizados quanto as variáveis agronômicas e teores de clorofila e carotenoides. Foi verificado que os híbridos 12 (UFU-189#3#4#1 × UFU MC BIOFORT 2) e 25 (UFU66#4#2 × UFU-189#3#4#1) possuem potencial para obtenção de populações de duplo propósito (produtividade e biofortificada para carotenoide). O híbrido 27 (UFU66#4#2 × UFU MC BIOFORT1) foi o que apresentou maior equilíbrio para pigmentos. Sugere-se a obtenção de populações F2 dos híbridos 12, 25 e 27 visando a obtenção de novas cultivares de alfaces biofortificadas vermelhas e verdes, para os segmentos de alface crespa, americana, mini e romana. mundial saúde Lactuca L.

Abstract Purpose: To identify the main links between the Localized Agri-Food Systems (SYAL = Systemes Agroalimentaires Localisés) approach and agroecology and determine the elements of agroecology that could strengthen SYAL to promote territorial patrimonialization. Methodological design: Through the qualitative approach and based on the systematic review of documentary and multimedia sources in the period 2010-2023, a content analysis was carried out to propose a critical path for territorial patrimonialization. Results: Both approaches seek the reconnection of food with the territory and recognize a quality that results from processes and products according to bioregions; distinguishing the territory as an element of identity; valuating traditional know-how and promoting local, collective action. Research limitations: There is a gap of studies from the SYAL approach that delves into the application of agroecological practices as a strategy to strengthen the quality linked to the territory, address the environmental dimension, and promote territorial patrimonialization. Findings: The agroecological principles emphasize the quality linked to the territory, and the SYAL approach the bioregional patrimonialization.

Resumen Objetivo: este estudio estima un sistema de demanda de bienes alimenticios en México, incorporando dimensiones territoriales y de ingreso. Se evalúa el impacto diferenciado de choques en los precios en el bienestar económico y la tasa de pobreza, considerando variaciones entre hogares y entre cinco grandes regiones. Metodología: utilizando el modelo de valores unitarios de Deaton (1988) y la Encuesta Nacional de Ingresos y Gastos de los Hogares (ENIGH) de 2018, calculamos elasticidades-precios y elasticidades-ingreso y el impacto de las variaciones de precios en el ingreso y la pobreza. Resultados: revelan importantes diferencias regionales y se subraya la necesidad de considerar diferencias socioeconómicas y regionales y de adoptar un enfoque territorial en este tipo de análisis y para formular políticas efectivas. Limitaciones: existen limitaciones a este estudio que pueden afectar la comprensión completa de la dinámica de la pobreza. Hemos enfocado nuestra atención únicamente en los bienes alimenticios, excluyendo un grupo específico de productos, en este caso, los productos pesqueros. También, se considera que los hogares son únicamente consumidores de bienes, omitiendo así la dimensión productiva de autoconsumo. Originalidad: radica en la vinculación directa entre las estimaciones de pobreza y la desagregación territorial, integra patrones de consumo y elasticidades específicas a cada región. Conclusiones: se resalta la importancia de considerar las diferencias socioeconómicas y regionales al analizar la demanda de bienes alimenticios y su impacto en la pobreza. A pesar de las limitaciones, nuestros hallazgos subrayan la necesidad de un enfoque territorial en este tipo de análisis para formular políticas adaptadas y efectivas de reducción de la pobreza en diferentes regiones del país.

Abstract Objective: this study estimates a system of demand for food products in Mexico, incorporating territorial and income dimensions. The differentiated impact of shocks on prices on economic well-being and the poverty rate is evaluated, considering variations among households and across five major regions. Methodology: using Deaton’s (1988) unit values model and the 2018 National Income and Expenditure Survey (ENIGH), we calculate price and income elasticities, examining the impact of price variations on income and poverty. Results: our results reveal significant regional differences, emphasizing the need to consider socioeconomic and regional variations and to adopt a territorial approach in such analyses for effective policy formulation. Limitations: there are limitations to this study that may affect a complete understanding of poverty dynamics. We have focused our attention solely on food products, excluding a specific group of products, in this case, fishery products. We also assume that households are only consumers of goods, thus omitting the productive and self-consumption dimension. Originality: lies in the direct link between poverty estimates and territorial disaggregation, integrating consumption patterns and specific elasticities for each region. Conclusions: our study highlights the importance of considering socioeconomic and regional differences when analyzing the demand for food products and its impact on poverty. Despite the limitations, our findings underscore the need for a territorial approach in this type of analysis to formulate tailored and effective poverty reduction policies in different regions of the country.

Abstract The payment of child support is one of the main challenges regarding gender equity and economic justice. Recent figures show that 84% of child support payments decreed by the family courts are not paid, and in nine out of ten cases the plaintiffs are women. This article explores the experiences of nonpayment of child support from a gender perspective. For this purpose, 18 semi-structured interviews were conducted with women in the cities of Antofagasta, Santiago de Chile, and Temuco, as part of a study on women’s economic autonomy in Chile. The findings show that non-payment of child support is closely linked to the persistence of the feminization of reproduction and the absence of co-responsibility in child-rearing and childcare. It is also related to a reluctance to request the payment of child support as a strategy to avoid economic dependence, vulnerability to violence, and institutional revictimization. This evidence suggests that nonpayment of child support constitutes a form of economic violence and that cultural norms and social dynamics with respect to gender are at the root of tensions over co-responsibility in the reproductive sphere.

Resumen El pago de las pensiones alimenticias es uno de los principales desafíos en torno a la equidad de género y a la justicia económica. Cifras recientes demuestran que el 84 % de las pensiones alimenticias decretadas por los tribunales de familia son incumplidas y en nueve de cada 10 casos las demandantes son mujeres. En el presente artículo se exploran las experiencias sobre el incumplimiento del pago de las pensiones alimenticias desde una perspectiva de género. Para ello, se realizaron 18 entrevistas semiestructuradas a mujeres de las ciudades Antofagasta, Santiago de Chile y Temuco en el marco de una investigación sobre autonomía económica de mujeres en Chile. Los hallazgos muestran que el incumplimiento del pago de las pensiones de alimentos está estrechamente vinculado a la persistencia de la feminización de la reproducción y a la ausencia de corresponsabilidad en la crianza y el cuidado de hijos e hijas. También se relaciona con la resistencia a solicitar el pago de pensiones de alimentos como estrategia para evitar la dependencia económica, la vulnerabilidad a la violencia y la revictimización institucional. Estas evidencias sugieren que el impago de las pensiones constituye una forma de violencia económica y que las normas culturales y dinámicas sociales con respecto al género están en la base de las tensiones sobre la corresponsabilidad en el ámbito reproductivo.

RESUMEN El comercio electrónico se ha convertido en una actividad global practicada por un número cada vez más creciente de personas que interactúan en el mercado de bienes y servicios. El objetivo de este estudio fue identificar y analizar las costumbres y hábitos de compras de los consumidores de Asunción y del Departamento Central de Paraguay en relación a las compras en línea. Se utilizó un enfoque cuali-cuantitativo y se aplicó una encuesta en formato electrónico a un total de 400 participantes residentes en las zonas de influencia del estudio. Se observo que gran parte de la población analizada utiliza este método de compras y qué lo hacen de manera frecuente, aunque con una clara preferencia por ciertos tipos de productos como es el caso de los alimentos, que mayormente son adquiridos vía servicios de delivery desde tiendas locales; y también los pedidos de ropas, que generalmente son adquiridos desde tiendas internacionales, aunque también provienen en un número importante de tiendas locales que ofrecen sus productos principalmente a través de redes sociales. Los resultados más relevantes señalan que la mayoría de los participantes ya realizan compras en línea y que estarían dispuestos a repetir las compras en esa modalidad, debido a que las experiencias en general han sido positivas. Como recomendación, se expresa que las empresas locales deberían invertir mayores recursos para dotar a sus negocios de un sistema de comercio electrónico que les permita concretar transacciones en línea incluyendo el proceso de cobros con distintos medios de pago.

ABSTRACT E-commerce has become a global activity practiced by an increasing number of people who interact in the market for goods and services. The objective of this study was to identify and analyze the customs and shopping habits of consumers in Asunción and the Central Department of Paraguay in relation to online shopping. A quantitative approach was used and a survey in electronic format was applied to a total of 400 participants residing in the areas of influence of the study. It was observed that a large part of the population analyzed uses this shopping method and that they do so frequently, although with a clear preference for certain types of products such as food, which are mostly purchased via delivery services from local stores; and also clothing orders, which are generally purchased from international stores, although they also come in a significant number from local stores that offer their products mainly through social networks. The most relevant results indicate that most of the participants already make purchases online and that they would be willing to repeat purchases in this modality, since the experiences have generally been positive. As a recommendation, it is expressed that local companies should invest more resources to provide their businesses with an e-commerce system that allows them to carry out online transactions, including the collection process with different means of payment.

Summary: The state of Chiapas presents degradation processes of dif ferent kinds, as a consequence of the current established agricultural model. It is estimated that, in the near future, the surface of the state of Chiapas will present more than 55% degradation, generating changes in the physical, chemical and biological properties of the soil, af fecting the quality of life of human beings, mainly due to scarcity of food. The objective of this research was to evaluate the quality of the soils in three municipalities of the central depression of Chiapas, Mexico. The analysis were interpreted taking NOM-021-SEMARNAT-2000 as a reference and were classified according to the world reference base (WRB), version 2014. For the evaluation of soil quality, the sustainable use of land subindex (SUSS). 144 soil samples corresponding to 21 profiles were analyzed. Of the 21 profiles studied, 17 present poor soil qualities, two a sensitive quality, one acceptable quality and one with good quality. Only two soil groups presented good fertility and are classified as Vertisols and Phaeozems, which present good quality and capacity to maintain sustainable agricultural production in this region.

Resumen: El estado de Chiapas presenta procesos de degradación de diferente índole, como consecuencia del actual modelo agrícola establecido. Se estima que, en el futuro cercano, la superficie del estado de Chiapas presente más de 55% de degradación, generando modificaciones en las propiedades físicas, químicas y biológicas del suelo; afectando la calidad de vida de los seres humanos, principalmente por escasez de alimentos. El objetivo de esta investigación fue evaluar la calidad de los suelos en tres municipios de la depresión central de Chiapas, México. Los análisis se interpretaron tomando como referencia la NOM-021-SEMARNAT-2000 y se clasificaron de acuerdo con la world reference base (WRB), versión 2014, para la evaluación de calidad del suelo se utilizó el subíndice de uso sustentable del suelo (SUSS). Se analizaron 144 muestras de suelo correspondientes a 21 perfiles. De los 21 perfiles estudiados, 17 presentan calidad de suelo pobre, dos calidades sensibles, uno calidad aceptable y uno con calidad buena. Solo dos Grupos de suelo presentaron buena fertilidad y son clasificados como Vertisols y Phaeozems, los cuales presentan buena calidad y capacidad para mantener producción agrícola sostenible en esta región.

Summary: Excessive use of chlorpyrifos affects the quality of agricultural soils causing negative effects on the safety of harvested food. The behavior of chlorpyrifos residues depends on soil properties, especially organic matter. Our aim in this research was to determine the effect of the application of vermicompost on the residual and dissipation of chlorpyrifos in an entisol soil of semi-arid climate with variations in its edaphic fertility. Four treatments were studied. T1: 7.5% vermicompost (V) and 92.5% soil (S); T2: 5% V and 95% S; T3: 2.5% V and 97.5% S; T4: 0% V and 100% S. The treatments were subjected to a seven-day incubation period. Subsequently, a dose of chlorpyrifos of 1.5 mg kg-1 as active ingredient was applied once for each treatment. A completely randomized design was used with three replicates for each treatment, forming 12 experimental units. The analytical determination of chlorpyrifos was carried out by high performance liquid chromatography (HPLC). The evaluations were carried out 1.7, 14, 28, 42, 70 and 98 days after the application of chlorpyrifos. The results showed that the incorporation of vermicompost to the soil at increasing levels promoted a decrease in the residual concentration of chlorpyrifos and facilitated its gradual dissipation. The chlorpyrifos dissipation curves correspond to a first order logarithmic equation where the effects of the treatments caused greater dissipation of chlorpyrifos as the evaluation period elapsed. At 98 days of evaluation, T1 registered lower residuality (0.786 m kg-1), higher daily dissipation rate (0.008) and lower half-life of chlorpyrifos (86.64 days). At the end of the research period, edaphic levels of P, K, EC and CEC increased while OM, N and pH decreased after vermicompost application.

Resumen: El uso excesivo de clorpirifos afecta la calidad de los suelos agrícolas provocando efectos negativos en la inocuidad de los alimentos cosechados. El comportamiento de los residuos de clorpirifos depende de las propiedades edáficas especialmente la materia orgánica. El objetivo de la investigación fue determinar el efecto de la aplicación de vermicompost en la residualidad y disipación de clorpirifos en un suelo entisol de clima semiárido con variaciones en su fertilidad edáfica. Se estudiaron cuatro tratamientos. T1: 7.5% vermicompost (V) y 92.5% suelo (S); T2: 5% V y 95% S; T3: 2.5% V y 97.5% S; T4: 0% V y 100% S. Los tratamientos fueron sometidos a un periodo de incubación de siete días. Posteriormente, se aplicó una dosis de clorpirifos de 1.5 mg kg-1 como ingrediente activo en una sola oportunidad por cada tratamiento. Se utilizó un diseño completamente al azar con tres repeticiones por cada tratamiento conformando 12 unidades experimentales. La determinación analítica de clorpirifos se efectuó por cromatografía líquida de alta resolución (HPLC). Las evaluaciones se realizaron a 1,7, 14, 28, 42, 70 y 98 días de la aplicación de clorpirifos. Los resultados demostraron que la incorporación de vermicompost al suelo en niveles crecientes promovió la disminución de la concentración residual de clorpirifos y facilitó su disipación de manera gradual. Las curvas de disipación de clorpirifos corresponden a una ecuación logarítmica de primer orden donde los efectos de los tratamientos ocasionaron mayor disipación de clorpirifos conforme transcurrió el periodo de evaluación. A 98 días de evaluación el T1 registró menor residualidad (0.786 m kg-1), mayor tasa de disipación diaria (0.008) y menor vida media de clorpirifos (86.64 días). Al final del periodo de investigación, los niveles edáficos de P, K, CE y CIC se incrementaron mientras que la MO, N y pH descendieron luego de la aplicación de vermicompost.

Abstract This study examines conversations with X user positions in Mexico about ultra-processed foods, which have recently been linked to obesity. Posts from 2019 and 2020 were identified through hashtags on the topics of "labeling," "ultra-processed," and "junk food." We used a mixed approach to identify word patterns and develop an analysis based on social network theory. We found 211,585 tweets and 904,484 retweets from 90,828 and 321,637 accounts, respectively. There was an emphasis on conversations during the legislative process, especially the hashtag #etiquetadoclaroya. The most intense interactions occurred in discussions about new front-of-package warnings. The most influential profiles belonged to the media, academia, and civil society. The food industry's involvement was limited, so its role in the debate is inconclusive. This method can be used in other countries to monitor discussions on regulations and other policies.

Resumen Este estudio examina conversaciones con posturas de usuarios de X en México acerca de los productos comestibles ultraprocesados, recientemente asociados con obesidad. Se identificaron publicaciones en 2019 y 2020 a través de hashtags en temáticas denominadas "etiquetado", "ultraprocesados" y "comida chatarra". Se utiliza un enfoque mixto para identificar patrones de palabras y desarrollar un análisis basado en la teoría de redes sociales. Se encontraron 211,585 tweets y 904,484 retweets de 90,828 y 321,637 cuentas, respectivamente. Hubo un énfasis en las conversaciones durante procesos legislativos, destacando el hashtag #etiquetadoclaroya. Las interacciones más intensas ocurrieron en las discusiones sobre un nuevo etiquetado de advertencia. Los perfiles más influyentes pertenecían a medios de comunicación, academia y sociedad civil. La participación de la industria alimentaria fue limitada, por lo que su papel en el debate no es concluyente. Este método puede usarse en otros países para monitorear la discusión de regulaciones o políticas.

Abstract The organic composition of 65 °% of urban solid waste of the Metropolitan District of Quito originates from food waste, which has negative environmental effects. The purpose of this study was to evaluate the factors related to food waste in homes in the capital and characterize urban solid waste management. The study is quantitative and exploratory. An association analysis was performed for the main categorical variables through calculation of statistical chi squared and an assessment of polychoric relation. A descriptive and multi-scale statistical analyses were performed for focus of the social metabolism to characterize waste management. A noteworthy element was the relation between expenses for purchase of food and non-alcoholic beverages in the last month-household income in the last month (p value < 5 %). Between 2012-2021, the most representative median for waste generation corresponded to the Eugenio Espejo administration, with 141470 t/ year, with a metabolic waste rate of 2.45E-05 (t/year). On the other hand, the Tumbaco administration obtained 30217 t/year and 1.22E-05 t/year, respectively.

ABSTRACT The recent global health crisis highlighted the fundamental role of family farming and public procurement policies in guaranteeing the human right to adequate food. This documentary analysis compares public procurement experiences (2019 to 2022) in a region of Brazil and another in Colombia, focusing on family farming from a gender perspective to identify challenges and best practices. Among the findings, it is noteworthy that although structured policies for public procurement already exist in Brazil, regional realities pointed to challenges during the period. Advances in Colombia were noted with the issuance of Law 2046 of 2020. In both countries, the low role of women in the ownership of rural properties and decision-making was evident, despite their participation in the rural family productive workforce.

RESUMEN La pasada crisis sanitaria mundial evidenció el papel fundamental de la agricultura familiar y las políticas de compras pública para garantizar el derecho humano a la alimentación adecuada. En este análisis documental, se compararon las experiencias de compras públicas (2019 a 2022), en una región de Brasil y otra de Colombia, de la agricultura familiar, desde una perspectiva de género, con el objetivo de identificar desafíos y buenas prácticas. Entre los hallazgos, se destaca que, aunque ya existen políticas estructuradas para las compras públicas en Brasil, la realidad regional señaló desafíos en el período. Se señalaron los avances en Colombia, con la expedición de la Ley 2046 de 2020. En ambos países se evidenció el bajo rol de la mujer en la titulación de las propiedades rurales y en la toma de decisiones, aunque se evidencia su participación en la fuerza productiva rural familiar.
