West African Monsoon influence on the summer Euro-Atlantic circulation
2011
International audience; The West African Monsoon (WAM) influence on the interannual variability of the summer atmospheric circulation over North Atlantic and Europe is investigated over the period 1971-2000. A set of sensitivity experiments performed through the Arpege-Climat atmospheric general circulation model is analyzed, using the so-called "grid-point nudging" technique, where the simulated atmospheric fields in the WAM region are relaxed towards the ERA40 reanalysis. Observations confirm that a sizable part of the Euro-Atlantic circulation variability is related to the WAM, with anomalies of reinforced convection in the Sudan-Sahel region associated with positive North Atlantic Oscil…
COVID-19, an opportunity for developing countries?
2020
The COVID-19 outbreak was declared by the World Health Organization (WHO) as global pandemic in March 2020. Considering the necessity to implement rapid response to control the pandemic and the fragility and the state of need of low income countries, it will be mandatory to develop a global approach in order to reduce the spread of infection and the creation of community viral reservoirs. So far, we could hypothesize a worst case scenario in which when the COVID-19 outbreak hits a peak in Africa and in low-income countries, the majority of such countries will be unprepared, with low resources allocated for affording the viral emergency and the consequences will be catastrophic with no lesso…

Potential predictability of crop impacting climate variables for East Africa and application to sorghum in the Mt Kenya area
2013
In Southern countries with rural low income populations, the vulnerability of rainfed agriculture to rainfall variability requires effective solutions to mitigate the effects of climatic hazards on crops. Predicting the characteristics of rainy seasons some time before they start should help the establishment of agricultural adaptation strategies to rainfall hazards. This is the objective of the present study, focused on East Africa (Kenya and northern Tanzania), and divided in three parts:- Define and document intra-seasonal descriptors (ISD) that will be considered in the predictability study. A new methodological approach has been developed in order to define the onset date (ORS) and the…
Nuevos sujetos urbanos en el audiovisual africano: del modernismo a la industrialización cultural
2010
La espectacular transformación de las ciudades africanas en las últimas décadas ha cumplido un papel fundamental en el desarrollo de nuevas subjetividades y en el surgimiento de lenguajes artísticos y culturales nuevos. Ya en los años sesenta, en el alba de las independencias políticas, los primeros cines africanos tematizaron insistentemente esa relación entre las nuevas geografías urbanas y los nuevos sujetos africanos. El modernismo cinematográfi co africano, de Ousmane Sembène a Abderramahne Sissako, ha puesto siempre a la ciudad en el corazón de sus refl exiones. En los últimos tiempos, la creciente industrialización de la producción audiovisual africana de la que el fenómeno de Nollyw…
Brokers in the tea trade between China and West Africa
2021
Brokers have played important roles in the trade of green tea between China and Mali, from the 19th century when tea first came to Mali up to the present. They mediate between tea buyers and sellers, work on their own account, use soft skills, knowledge and networks and make a living from the commission they gain. This article examines the work of brokers in the tea trade, the social constellations in which they are active and the scope of their activity. Based on extensive field research in Mali and China, this article shows how brokers create their own jobs in a dynamic business landscape, which is often delimited by governmental policies, competing entrepreneurial activities and social …

Police violence in West Africa : Perpetrators' and ethnographers' dilemmas
2012
This article explores the use of violence by police officers and gendarmes in Ghana and Niger. We analyse how popular discourses, legal and organizational conditions frame the police use of violence. Acts of violence by police are situated in this inconsistent framework and can be seen as legal and appropriate, despicable and brutal, or as useful and morally legitimate. Thus, every time the police use violence, they face a major dilemma: legally and morally justified violence can be a source of long-term legitimacy; but because of multiple possible readings of a certain situation (according to different, conflicting moral and legal discourses), the very same action has potentially delegiti…
