“…People must be aware of the degree to which their activities affect air quality. According to the World Health Organisation, a substantial portion of global pollution is breathed, and one out of every eight deaths is caused by air pollution diseases with a projected 28,000 Ghanaians dying annually from air pollution-related diseases [6]. Ghana lost between $226 million and $300 million in 2015 due to air pollution diseases, according to a study by the Environmental Protection Agency (EPA).…”

Air pollution poses a challenge to human life, meanwhile, air quality in human inhabitancy is usually given less attention. Therefore, the study aims at assessing air pollution at Takoradi Technical University (TTU-Akatakyi campus) and its environs. The assessment was done to determine the particulate matter in the study area using a Haz-dust Monitor-5000. Before data collection, the sampler was calibrated and set to start for 24 hours. Data recorded were analysed using Microsoft Office Excel. The results were compared to EPA-Ghana and WHO Guidelines Values. TTU Akatakyi Campus, Bokro Township, and Diamond Cement Factory recorded mean PM1 values of 3.10, 3.19, and 3.56 mg/m3, respectively. The highest PM2.5 mean value (3.57 mg/m3) was recorded at Diamond Cement Factory whereas the least PM2.5 (3.11mg/m3) was at TTU-Akatakyi Campus. The highest PM10 mean value (3.80 mg/m3) was recorded at Diamond Cement Factory while the least (3.12 mg/m3) was at TTU Akatakyi Campus. The highest recorded Total Suspended Particulate (TSP) mean value (3.62 mg/m3) was at Diamond Cement Factory while the least (3.11 mg/m3) was at TTU Akatakyi Campus. The recorded values were above EPA-Ghana and WHO guidelines, which implies that the air quality in the study area at the time of the study was harmful to human health.

Climate change leading to Climate extremes in the twenty-first century is more evident in megacities across the world, especially in West Africa. The Greater Accra region is one of the most populated regions in West Africa. As a result, the region has become more susceptible to climate extremes such as floods, heatwaves, and droughts. The study employed the Coupled Model Intercomparison Project 6 models in simulating climate extreme indices under the Shared Socioeconomic Pathway scenarios (SSPs) over West Africa between 1979 and 2059 as exemplified by the Greater Accra region. The study observed a generally weak drought in the historical period and expected to intensify especially under SSP585 in Greater Accra. For instance, continuous dry days (CDD) reveal an increasing trend under the SSPs. Similarly, the overall projected trend of CDD over West Africa reveals an increase signifying a more frequent and longer drought in the future. The flood indices revealed a surge in the intensity and duration of extreme precipitation events under the SSPs in the region. For instance, R99pTOT and Rx5days are expected to significantly increase under the SSPs with intensification under the SSP245, SSP370, and SSP585. A similar trend has been projected across West Africa, especially along the Guinean coast. The study foresees a gradual and intensifying rise in heatwave indices over the Greater Accra region. The warming and cooling indices reveal an increasing and decreasing trend respectively in the historical period as well as under the SSPs particularly within urban centers like Accra and Tema. Most West African countries are projected to observe more frequent warm days and nights with cold nights and days becoming less frequent. Expected effects of future climate extreme indices pose potential threats to the water, food, and energy systems as well as trigger recurrent floods and droughts over Greater Accra. The findings of the study are expected to inform climate policies and the nationally determined contribution of the Paris Agreement as well as address the sustainable development goal 11 (Sustainable cities) and 13 (Climate action) in West Africa.
