Recent times have witnessed wildfires causing harm to both ecological communities and urban–rural regions, underscoring the necessity to comprehend wildfire triggers and assess measures for mitigation. This research hones in on Cartagena del Chairá, diving into the interplay between meteorological conditions and land cover/use that cultivates a conducive environment for wildfires. Meteorologically, the prevalence of wildfires is concentrated during boreal winter, characterized by warm and dry air, strong winds, and negligible precipitation. Additionally, wildfires gravitate toward river-adjacent locales housing agriculture-linked shrubs, notably in the northern part of the zone, where a confluence of land attributes and meteorological factors synergize to promote fire incidents. Employing climate scenarios, we deduced that elevated temperature and reduced humidity augment wildfire susceptibility, while wind speed and precipitation discourage their propagation across most scenarios. The trajectory toward a warmer climate could instigate fire-friendly conditions in boreal summer, indicating the potential for year-round fire susceptibility. Subsequently, via machine-learning-driven sensitivity analysis, we discerned that among the scrutinized socio-economic variables, GINI, low educational attainment, and displacement by armed groups wield the most substantial influence on wildfire occurrence. Ultimately, these findings converge to shape proposed wildfire mitigation strategies that amalgamate existing practices with enhancements or supplementary approaches.

The systematic review permitted the characterization of training programs in digital teaching competence using an analysis of their structure, implementation, and results. A comprehensive search was conducted across five databases, namely Scopus, Web of Science, Redalyc, Science Direct, and LENS, to retrieve scientific articles published between 2017 and 2023. The search was conducted using the inclusion-exclusion criteria, and the articles were selected to answer five guiding questions. The review addressed five aspects: initiatives and practices, configuration, implementation, concrete results, and dimensions according to recurrent frames of reference. It was observed that there has been an improvement in digital competence and teacher motivation, with elements such as information literacy, communication, digital content creation, and information security. However, there is a lack of alignment with current needs. It is important to articulate with reference frameworks such as DigCompEdu. To prepare future teachers and train active ones, it is suggested that conceptual, procedural, and attitudinal aspects be considered.

The risk imposed upon society by consumption of foods contaminated with metals and metalloids is an environmental problem attributed to the increasing number of mining extraction activities currently underway in Colombia. The aim of the current study was to determine concentrations of mercury (Hg), lead (Pb), cadmium (Cd), and a metalloid arsenic (As) found in the species of most consumed fish species by citizens of Bogota D.C. (Colombia), and the consequent potential risk to human health was also calculated. Muscle samples of 8 fish species were obtained from 203 individuals collected through 2014. The highest metal concentrations detected were as follows: Pb in Oncorhynchus sp. (0.0595 mg/kg), Cd and Hg in Pimelodus sp. (0.0072 and 0.0579 mg/kg, respectively), and As in Scomberomorus sp (0.0471 mg/kg). Further, the levels of metal accumulation from consumption of fish were calculated utilizing the metal pollution index (MPI), with elevated values noted in Pseudoplatystoma sp (0.06 mg/kg), followed by Scomberomorus sp. and Centropomus sp. (0.05 and 0.04 mg/kg, respectively). The multiple species exposure index (E_m.j) denotes the level of exposure associated with consumption of various contaminated fish species, and this level occurred in decreasing order as follows: As > Pb > Cd > Hg. The multiple chemical exposure index (E_j.m), which accounts for exposure to multiple metals, identified Prochilodus sp. as the species displaying the highest level of exposure per consumption (8 × 10⁻⁶ mg/kg-d). The target hazard quotient (THQ) for human health indicated high levels for Hg and Cd in Prochilodus sp. (0.026 and 0.005, respectively), Pb in Oncorhynchus sp (0.025), and As in Pseudoplatistoma sp. and Centropomus sp. (0.023). Data emphasize the need for adequate nationwide public policies that promote assessment of exposure levels and potential adverse health risks associated with dietary consumption of different fish species in Colombia.
