Article Synopsis
- Mapping geographical accessibility to health services is crucial for improving public health in sub-Saharan Africa, but the effectiveness of different methods in reflecting actual accessibility experiences is not well established.
- The study compares four methods of estimating accessibility—Euclidean distance, cost-distance, and Kernel density—using open datasets across 12 sub-Saharan countries, correlating these with perceived accessibility from Demographic and Health Surveys.
- Results indicate that simpler methods like Euclidean distance often suffice, especially in rural areas without motorized transport, raising questions about the need for more complex approaches in certain contexts.
In recent years, as in other parts of the Sahel, the threat of terrorism has escalated in Burkina Faso. In 2019, this country hosted the fourth highest number of new conflict-related internal displaced persons (IDPs) in the world. These people have to cope simultaneously with the full spectrum of environmental, social and health-related stresses in the long, medium and short term, respectively.

Data on both health determinants and health outcomes are often lacking or are of poor quality. Proxies associated with socioeconomic differences are needed to compensate the lack of data.

Based on a systematic literature review, this paper aims to learn more about the relationship between desert dust and human health in the world and to analyse the place of West Africa as a study area of interest. Papers focussing on the potential relationship between dust and health and showing quantitative analyses, published between January 1999 and September 2011, were identified using the ISI Web of Knowledge database (N = 50).

Based on a systematic review of the literature using the ISI Web of Knowledge database, we found 231 articles published over the last decade on the desert dust impacts on air quality. Of these, 48% concerned Asian dust and 39% Saharan dust, with the remaining 13% divided between the other dust source areas.
