Marogong, nestled in the province of Lanao del Sur, Philippines, occupies a geographically significant position within the expansive Lake Lanao basin. Located at approximately 7.67° N, 124.15° E, the municipality’s terrain is characterized by undulating hills and valleys, typical of the mountainous region of Mindanao. The elevation ranges from around 600 to 800 meters above sea level, influencing local climate patterns and air circulation. Lake Lanao, a massive tectonic lake, dominates the regional landscape and exerts a considerable moderating effect on temperature and humidity. The lake’s presence also contributes to localized fog formation, particularly during the cooler months. Surrounding Marogong, the landscape transitions from agricultural lands – primarily rice paddies and small-scale farms cultivating fruits and vegetables – to denser forested areas, part of the broader Mindanao biodiversity hotspot. The urban–rural gradient is relatively sharp, with Marogong representing a small, primarily agricultural town. While there isn't a major industrial belt directly adjacent to Marogong, the proximity to larger urban centers like Marawi City introduces potential for transboundary pollution. Agricultural practices, including burning of crop residues after harvest, can contribute to localized air pollution events. The topography, with its hills and valleys, can trap pollutants, especially during periods of low wind speed, impacting air quality within the municipality. The prevailing winds, influenced by the lake and surrounding mountains, play a crucial role in dispersing or concentrating airborne particles.

Marogong’s tropical climate dictates a wet and dry season pattern, significantly influencing air quality dynamics. The dry season, typically spanning from March to May, often sees a slight increase in particulate matter due to agricultural burning practices. Farmers clearing fields after harvests frequently resort to controlled burns, releasing smoke and ash into the atmosphere. While these burns are often localized, the topography can trap the smoke, leading to temporary reductions in visibility and potential respiratory irritation. The wet season, from June to November, brings frequent rainfall and higher humidity, generally leading to improved air quality as precipitation washes away pollutants. However, periods of prolonged rainfall can also lead to increased fungal spore counts, impacting air quality for individuals with allergies or respiratory sensitivities. During the transition months (February and December), fog formation, facilitated by the lake’s influence and cooler temperatures, can trap pollutants near the ground, creating localized pockets of poor air quality. Temperature inversions, where cooler air is trapped beneath warmer air, are less frequent but can occur, exacerbating pollution events. The monsoon season (July-September) brings strong winds that generally disperse pollutants, but heavy rainfall can also lead to flooding, which can stir up dust and sediment, temporarily degrading air quality. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should limit outdoor activity during periods of agricultural burning and fog, and monitor local conditions. Staying indoors with air purifiers can also provide relief.
