Abstract. A number of campaigns have been carried out to establish the emission factors pollutants from fuel combustion in West Africa, as part work package 2 (“Air Pollution and Health”) DACCIWA (Dynamics-Aerosol-Chemistry-Cloud Interactions Africa) FP7 program. Emission sources considered here include wood (hevea iroko) charcoal burning, making, open trash vehicle emissions, including trucks, cars, buses two-wheeled vehicles. total particulate matter (TPM), elemental carbon (EC), primary...
ABSTRACT Dust generation and transportation from North Africa are thought to modulate the West African Monsoon ( WAM ) features. In this study, we investigated relationship between Saharan Air Layer located above Atlantic Ocean OSAL features, including flow, Easterly Jet AEJ Tropical TEJ over using RegCM4 regional model at 30 km grid resolution. Two sets of experiments with without dust load were performed 2007 2013 simulation domain, encompassing whole a large part adjacent Ocean. An...
Urban populations face increasing vulnerability to extreme heat events, particularly in rapidly urbanising Global South cities where environmental exposure intersects with socioeconomic inequality and limited healthcare access. This study quantifies across Johannesburg, Africa, by integrating high-resolution data socio-economic health metrics 135 urban wards. We examine how historical development patterns influence contemporary distributions using principal component analysis spatial...
Traffic source emission inventories for the rapidly growing West African urban cities are necessary better characterization of local vehicle emissions released into atmosphere these cities. This study is based on field measurements in Yopougon (Abidjan, Côte d’Ivoire) 2016; a site representative anthropogenic activities The provided data type and age, traveling time, fuel type, estimated amount consumption. revealed high traffic flow personal cars highways, boulevards, backstreets, whereas...
This modeling study is conducted to examine the potential impact of reforestation (greenbelt) location (either in Sahel or Guinean region) on West African summer climate system. To this end, three simulations using regional model RegCM4 driven by ERA-Interim reanalysis were performed at 50 km horizontal resolution over a domain for period 2000–2011. The first experiment, namely control (CTRL), uses standard vegetation cover, while two others incorporate throughout integration, zonal band...
Road traffic emission inventories based on bottom-up methodology, are calculated for each road segment from fuel consumption and volume data obtained during field measurements in Yopougon. High emissions of black carbon (BC) vehicles observed at major intersections, areas surrounding industrial zones highways. Highest values monoxide (CO) (14.8 t/d) nitrogen oxides (NOx) (7.9 t/d), usually considered as the pollution tracers. Furthermore, peak CO due to personal cars (PCs) mainly linked old...
Traffic source emissions inventories for the rapidly growing West African urban cities are necessary better local characterization of vehicle released into these atmosphere. This study based on field campaign in a representative site anthropogenic activities over such as Yopougon (Abidjan, Côte d'Ivoire) during 2016, provided useful information type and age, traveling time, fuel amount consumption estimation. Also, high traffic flow personal car were recorded highway, boulevard...
Malaria continues to be a major public health concern with substantial burden in Africa. Even though it has been widely demonstrated that malaria transmission is climate-driven, there have very few studies assessing the relationship between climate variables and Côte d’Ivoire. We used VECTRI model predict southern First, we tested suitability of modeling using ERA5 temperature data ARC2 rainfall data. then projected climatic pertaining 2030, 2050, 2080 from set 14 simulations CORDEX-Africa...
Black carbon is one of the primary aerosols directly emitted from biomass known to have strong absorbing properties. The INDAAF and PASMU observational field campaigns which took place (2018) in Abidjan (urban area) Lamto (rural allow analysis concentration at different time scales through real-time measurements using an analyzer named Aethalometer AE-33. Results presented here show Lamto: 1) for diurnal scale average 1.71 ± 0.3 μg⋅m-3 (0.34 0.09 μg⋅m-3) dry (wet) season; 2) monthly 1.14...
Climate variability impacts on cocoa production are evaluated for the first time using 31 years (1979-2010) of data from SODEXAM (climate ground- based observations) and ex-CAISTAB in three main regions (Goh, Marahoué, Haut-Sassandra) west-central part Cote d’Ivoire. The work is a contribution to improving quality climate services dedicated cultivation ensure producers’ income improve yield results show that affected by changes conditions (i.e. rainfall temperature). In Goh region, increase...
In this study, the long term trend of observed visibility data used directly (without conversion into dust concentrations) over Sahel was investigated between 1957 and 2013. Then, to review influence atmospheric factors land surface conditions on trend, coevolution mass concentration from MERRA-2 (Modern-Era Retrospective analysis for Research Applications) reanalysis, in-situ meteorological (rainfall, relative humidity, wind speed, air temperature), as well Normalized Difference Vegetation...

Emission sources considered here include wood charcoal burning, making, open waste vehicles including trucks, cars, buses two-wheeled vehicles. total particulate matter, black carbon, primary organic carbon non-methane volatile...
Air pollution can severely impact child lung health but is often not considered a public priority by policy-makers and population in low-and-middle income countries. We did an interdisciplinary mixed method study to assess exposure air respiratory children aged 5-10 living poorly condition Yopougon, district of Abidjan, Côte d’Ivoire, parent perceptions knowledge pollution. assessed with indoor outdoor PM10 PM2.5 concentrations questionnaires, children’s ISAAC questionnaire, clinical...
Malaria is the leading cause of morbidity among children under five years age and pregnant women in Côte d'Ivoire. We assessed geographical distribution its risk all climatic zones country based on Fifth Assessment Report (AR5) United Nations Intergovernmental Panel Climate Change (IPCC) approach to climate analysis. This methodology considers three main driving components affecting risk: Hazard, exposure vulnerability. Considering malaria impact chain, various variables were identified for...
