Aquitania, nestled within the department of Boyacá, Colombia, occupies a geographically significant position in the Eastern Andean foothills. Located at approximately 5.58° N, 72.83° W and an elevation of roughly 2,150 meters (7,050 feet) above sea level, the city’s terrain is characterized by steep slopes and valleys typical of the Colombian Andes. The surrounding landscape is dominated by rolling hills covered in a mosaic of agricultural land – primarily coffee and potato cultivation – and patches of cloud forest. This agricultural activity, while vital to the regional economy, contributes to localized air quality concerns, particularly during harvesting and processing seasons. Aquitania sits within a transitional zone, exhibiting a gradual urban–rural gradient. While it maintains a distinctly rural character, with a relatively small population of 16,087, it serves as a local commercial hub for surrounding agricultural communities. The Chicamocha River, though not directly adjacent, flows nearby, influencing local microclimates and humidity levels. The city’s location within a valley can exacerbate air pollution episodes, as topographical features can trap pollutants and limit dispersion. There are no major industrial belts immediately surrounding Aquitania; however, transportation routes connecting Boyacá to other regions pass through the area, contributing to vehicular emissions. The prevailing winds, generally flowing from the east, play a crucial role in dispersing or concentrating pollutants, depending on atmospheric stability.

Aquitania’s tropical highland climate dictates a distinct wet and dry season pattern, significantly influencing air quality throughout the year. The dry season, typically spanning December to March, often sees a slight improvement in air quality due to increased sunshine and stronger winds that aid in pollutant dispersal. However, this period can also experience periods of stagnant air, particularly when high-pressure systems settle over the region, leading to temperature inversions that trap pollutants near the ground. Agricultural burning, a common practice for land clearing and crop residue disposal, is most prevalent during this time, contributing to particulate matter pollution. The wet season, from April to November, brings frequent rainfall, which naturally helps to cleanse the atmosphere by removing particulate matter. However, increased humidity can exacerbate respiratory issues for sensitive individuals. Fog, common during the cooler months (December-February), can trap pollutants, creating localized episodes of reduced visibility and poorer air quality. During the harvest season (typically June-August), increased agricultural activity, including processing and transportation of crops, leads to elevated levels of dust and emissions. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during periods of agricultural burning and fog, limiting outdoor exertion and wearing appropriate masks when necessary. The cooler temperatures during the dry season can also trigger asthma attacks in susceptible individuals, highlighting the importance of proactive respiratory management.
