Jalingo, the capital of Taraba State in northeastern Nigeria, occupies a strategic position at the geographic heart of the Middle Belt region, where the savanna grasslands of northern Nigeria transition toward the forested zones of the south. Situated at coordinates 8.9000°N, 11.3667°E with an elevation of approximately 350 meters above sea level, the city lies within the Benue River basin, though it is not directly adjacent to major water bodies, with the Benue River flowing about 50 kilometers to the south. This elevated plateau location, surrounded by the scenic Mambilla Plateau to the southeast and the Shebshi Mountains to the northeast, creates a natural amphitheater that can trap air pollutants under certain meteorological conditions. Jalingo's urban character blends administrative functions with growing commercial activity, set against a backdrop of agricultural hinterlands where subsistence farming dominates, particularly for crops like maize, yams, and sorghum. The city's expansion follows an urban–rural gradient with peri-urban areas merging into farmlands, contributing to seasonal biomass burning from agricultural residues. Its position along major transportation routes connecting northeastern Nigeria to the rest of the country exposes it to vehicular emissions, while the lack of heavy industry means pollution stems primarily from general urban sources like transportation, domestic fuel use, and dust from unpaved roads. The surrounding dry savanna landscape, with its sparse vegetation during the dry season, allows wind-blown dust to become a significant contributor to particulate matter, especially when Harmattan winds sweep south from the Sahara Desert.

Jalingo's air quality follows a distinct seasonal pattern shaped by the West African monsoon cycle, with pollution levels fluctuating between the dry and wet seasons. During the dry season from November to March, air quality deteriorates significantly due to the influx of Harmattan winds, which carry fine dust particles from the Sahara Desert, typically peaking in December and January. These months see reduced visibility and elevated particulate matter, exacerbated by temperature inversions that trap pollutants near the ground, especially during cool nights and early mornings. Sensitive groups like asthmatics, children, and the elderly should limit outdoor activities during this period and use protective masks. The transition to the wet season from April to October brings relief as rainfall scrubs the atmosphere, with the heaviest rains from June to September dramatically improving air quality by suppressing dust and washing away pollutants. However, occasional pre-monsoon haze in April and May can cause temporary spikes in pollution. The wet season offers the best conditions for outdoor exercise and activities, particularly from July to September when air is cleanest. Throughout the year, local sources like vehicular emissions and domestic burning of biomass for cooking contribute to baseline pollution, but the seasonal meteorological drivers—Harmattan dust in the dry season and cleansing rains in the wet—create the most pronounced variations in air quality, making timing crucial for health planning in this savanna city.
