Structural violence against children in Chihuahua

Hector Castro-Loera Gabriela Orozco Lopez (2022, [Artículo, Artículo])

Within the framework of philosophy and its social function, structural violence against children in Chihuahua is studied; To approach the phenomenon and propose alternatives, three theories will be related: i) feminist studies regarding violence, concepts such as intersectionality, pedagogies of cruelty and structural violence will be used, ii) the philosophy of children's rights, child´s play will be appreciated as a necessity and legal position of freedom, and iii) the event of the Aufklärung, that is, the assimilation of the present of humanity or the Enlightenment in Foucault's thought.

UN PASEO POR TIJUANA: UNA REFLEXIÓN ETNOGRÁFICA SOBRE LA COTIDIANIDAD Y EL IMPACTO DE LAS CARAVANAS DE MIGRANTES EN TIJUANA, BAJA CALIFORNIA, MÉXICO.

Victor Vazquez Mariana Gutierrez (2022, [Artículo, Artículo])

Resumen:

El siguiente articulo presenta una reflexión antropológica y urbana centrada en la vida diaria y los principales problemas incluyendo: el impacto de las caravanas de migrantes, y cuestiones urbanas en Tijuana durante los años 2018 – 2021. En adición, el articulo aborda otros temas importantes como: el impacto de la pandemia del COVID-19, y los patrones socioculturales históricos desarrollados para sobrevivir las condiciones de desigualdad económica en Tijuana. A nivel metodológico, el articulo utilizó un enfoque cualitativo basado en experiencias de trabajo de campo que incluyeron observación participante y múltiples entrevistas realizadas a residentes durante distintas visitas a Tijuana, Baja California, México entre los años 2018-2021. Las conclusiones de este articulo presentan una reflexión para entender y hacer visible las condiciones de vida de los migrantes, los esfuerzos brindados por una organización de migrantes y el estilo de vida único y problemas urbanos contemporáneos desarrollados en la ciudad fronteriza de Tijuana.

Farmers’ perspectives as determinants for adoption of conservation agriculture practices in Indo-Gangetic Plains of India

Ajay Kumar Mishra ML JAT (2022, [Artículo])

Understanding the farmer's perspective has traditionally been critical to influencing the adoption and out-scaling of CA-based climate-resilient practices. The objective of this study was to investigate the biophysical, socio-economic, and technical constraints in the adoption of CA by farmers in the Western- and Eastern-IGP, i.e., Karnal, Haryana, and Samastipur, Bihar, respectively. A pre-tested structured questionnaire was administered to 50 households practicing CA in Western- and Eastern-IGP. Smallholder farmers (<2 ha of landholding) in Karnal are 10% and Samastipur 66%. About 46% and 8% of households test soil periodically in Karnal and Samastipur, respectively. Results of PCA suggest economic profitability and soil health as core components from the farmer's motivational perspective in Karnal and Samastipur, respectively. Promotion and scaling up of CA technologies should be targeted per site-specific requirements, emphasizing biophysical resource availability, socio-economic constraints, and future impacts of such technology.

The potential of UAV and very high-resolution satellite imagery for yellow and stem rust detection and phenotyping in Ethiopia

Gerald Blasch David Hodson Francelino Rodrigues (2023, [Artículo])

Very high (spatial and temporal) resolution satellite (VHRS) and high-resolution unmanned aerial vehicle (UAV) imagery provides the opportunity to develop new crop disease detection methods at early growth stages with utility for early warning systems. The capability of multispectral UAV, SkySat and Pleiades imagery as a high throughput phenotyping (HTP) and rapid disease detection tool for wheat rusts is assessed. In a randomized trial with and without fungicide control, six bread wheat varieties with differing rust resistance were monitored using UAV and VHRS. In total, 18 spectral features served as predictors for stem and yellow rust disease progression and associated yield loss. Several spectral features demonstrated strong predictive power for the detection of combined wheat rust diseases and the estimation of varieties’ response to disease stress and grain yield. Visible spectral (VIS) bands (Green, Red) were more useful at booting, shifting to VIS–NIR (near-infrared) vegetation indices (e.g., NDVI, RVI) at heading. The top-performing spectral features for disease progression and grain yield were the Red band and UAV-derived RVI and NDVI. Our findings provide valuable insight into the upscaling capability of multispectral sensors for disease detection, demonstrating the possibility of upscaling disease detection from plot to regional scales at early growth stages.
