Policy-relevant findings of the DACCIWA project
The EU funded project Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA) produced the most comprehensive observational dataset of the atmosphere over southern West Africa to date.
Analysing this dataset in combination with results of numerical modelling has led to the conclusions described in this executive summary. In particular, the authors of the report highlight the high concentrations of particulate matter in the region, which have a significant impact on the health of populations. The greatest health risk identified is that of open fires used for domestic cooking. Finally, the authors point out a lack of inventory data for the region, leading to an underestimation of air pollutant emissions related to human activities.
