Abstract. One of the critical aspects in modelling soil organic carbon (SOC) predictions is the lack of access to soil information which is usually concentrated in regions of high agricultural interest. In Chile, most soil and SOC data to date is highly concentrated in 25 % of the territory that has intensive agricultural or forestry use. Vast areas beyond those forms of land use have few or no soil data available. Here, we present a new database of SOC for the country, which is the result of an unprecedented national effort under the frame of the Global Soil Partnership that help to build the largest database on SOC to date in Chile named “CHLSOC" comprising 13,612 data points. This dataset is the product of the compilation from numerous sources including unpublished and difficult to access data, allowing to fill numerous spatial gaps where no SOC estimates were publicly available before. The values of SOC compiled in CHLSOC range from 6×10−5 to 83.3 percent, reflecting the variety of ecosystems that exists in Chile. Profiting from the richness of geochemical, topographic and climatic variability in Chile, the dataset has the potential to inform and test models trying to predict SOC stocks and dynamics at larger spatial scales.

Análisis espacio-temporal del incumplimiento de normas legales sobre el confinamiento en Colombia por COVID-19Spatial and temporal analysis of the breach of legal regulations regarding the Colombian COVID-19 lockdown Análise espaço-temporal da infringência de normas legais sobre o confinamento na Colômbia pelo COVID-19
El objetivo de este trabajo fue conocer las relaciones entre las cifras de incumplimiento de siete restricciones impuestas por el aislamiento social establecido por la Covid-19 (Comportamientos Contrarios a la Convivencia, CCC) entre el 16 de marzo y el 1 de mayo de 2020, con indicadores económicos de criminalidad, de tejido social entre 2015 y 2018, y con el número de contagios del 2020 a nivel nacional y en Bogotá (n = 33). Entre los resultados se encontró a) correlación directa entre las tasas totales de CCC y tasas regionales de delitos contra la propiedad; b) relaciones directas entre infracciones por aglomeraciones y tasa de contagios por Covid-19; c) el clima emocional negativo y la insatisfacción con la policía se asociaron con infracciones por aglomeraciones y por falta de uso del tapabocas; d) más eficacia colectiva y afrontamiento comunal se asociaron con menos infracciones por consumo no autorizado de alcohol Aunque el tamaño de las correlaciones fue moderado, la evidencia apoya las teorías de la “ventana rota” y de la desorganización social.
