Étude des conditions de préparation des médicaments issus de la pharmacopée traditionnelle au Bénin et au Burkina Faso

Introduction: Traditional medicine has become an important component in the care system of African populations. Many products derived from it are increasingly used in the therapeutic arsenal. This work is an inventory of the production of these drugs in two countries of West Africa, Burkina Faso and Benin. Methods: A cross-sectional descriptive study that listed the drug manufacturing units producing medicines derived from the traditional pharmacopoeia (MDTP) identified by the health ministries in the two countries was carried out. Results: Thirty-three production facilities, including 10 in Burkina Faso and 23 in Benin, were surveyed. Seven units surveyed in Burkina Faso and 16 in Benin were illegally installed. Only 16 of the 33 units obtain their raw materials from botanical gardens. The rest obtain theirs through picking which is not favorable to the perpetuation of the plant resource. In addition, among the 1041 MDTPs manufactured by the units surveyed, only 1.44% are registered. Finally, shortcomings in applying good practices for harvesting raw materials and manufacturing finished products were noticed. Conclusion: Management and capacity building efforts of MDTPs production facilities by political authorities are still needed to optimize the contribution of traditional medicine to the health care of African populations

Potential of video cameras in assessing event and seasonal coastline behaviour: Grand Popo, Benin (Gulf of Guinea)

n this study, we explore the potential of a nearshore video system to obtain a long-term estimation of coastal variables (shoreline, beach slope, sea level elevation and wave forcing) at Grand Popo beach, Benin, West Africa, from March 2013 to February 2015. We first present a validation of the video system with field data over a 10-day experiment conducted on Grand Popo beach in 2014. Secondly, 2-years daily and monthly timeseries are extracted and their variability is described as a function of regional forcing and climatic modes. All variables show large monthly variability. The longshore sediment transport estimated locally from video is in agreement with that derived from Era-Interim wave data re-analyses. Results show that the shoreline responds predominantly to tides at the event scale and to waves. Overall, this study suggests that video stations are efficient tools to monitor coastal processes over the long term, in complement with other conventional approaches. Although no clear conclusions can be drawn on inter-annual variability, the results show that it is important to build up extended coastal observation networks to address coastline changes over a wide range of scales
