Throughout history, there have been periods of civil unrest. From religious wars to wars of conquest, historians believe that the causes of wars are closely related with religious, political or economic reasons. But when we discuss about civil unrest inside a country with the power of transforming it into a civil war and expanding at regional level, the triggering factors have yet to be discovered. From the period of the Qing Dinasty (1644-1911) in China to the Great Depression in the 1930s in the USA or the beginning of the second World War in France, these periods have two common points: civil unrest and food shortages.

The world agrifood system continues to be in a vulnerable state as we fast approach the 2015 deadline for the Millennium Development Goal of halving the proportion of people suffering from hunger. Although a number of countries have made important changes towards developing food related policies, at the level of the global community, the challenge of food (in)security has not been able push policy makers to develop a common solution to be applied, solution that could include the regional and national specificities registered around the world, while also integrating a global view of increasing agricultural productivity, higher farm competitiveness and without relinquishing the national or individual right for food governance.

The multicolored Asian ladybeetle, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), was introduced into Western Europe in the late 1990s. Since the late 2000s, this species has been commonly considered one of the most abundant aphid predators in most Western European coun- tries. In spite of the large amount of research on H. axyridis, information concerning its relative abundance in agroecosystems is lacking. This study aims to evaluate the abundance of H. axyridis within the aphidophage community in four crops situated in southern Belgium: wheat, Triticum aestivum L. (Poales: Poaceae), corn, Zea mays, potato, Solanum tuberosum (Solanales: Solanaceae), and broad bean Vicia faba (Fabales: Fabaceae). In order to assess the species diver- sity, the collected data were analyzed by considering (1) the species richness and (2) the evenness according to the Shannon diversity index. Eleven aphidophages were observed in every invento- ried agroecosystem, including five abundant species: three coccinellids, the seven-spotted ladybug, Coccinella septempunctata L. (Coleoptera: Coccinellidae), the 14-spotted Ladybird, Propylea quatuordecimpunctata, and H. axyridis; one hoverfly, the marmalade hoverfly, Episyr- phus balteatus De Geer (Diptera: Syrphidae); and one lacewing, the common green lacewing, Chrysoperla carnea Stephens sensu lato (= s.l.) (Neuroptera: Chrysopidae). Harmonia axyridis has been observed to thrive, breed, and reproduce on the four studied crops. Harmonia axyridis is the most abundant predator of aphids in corn followed by C. septempunctata, which is the main aphid predator observed in the three other inventoried crops. In wheat and potato fields, H. axyridis occurs in low numbers compared to other aphidophage. These observations suggest that H. axyridis could be considered an invasive species of agrosystems, and that potato and wheat may intermittently act as refuges for other aphidophages vulnerable to intraguild predation by this invader. Harmonia axyridis is not the most abundant aphid predator in the main Belgian crops. [less ▲]

Bacillus subtilis is a PGPR (Plant Growth Promoting Rhizobacterium) Gram positive bacterium and a model for studying the in vitro formation or disruption of biofilms. At the liquid/air interface of standing cultures, B. subtilis forms thick pellicles of limited lifetimes. Some D-amino acids have been reported among the factors playing a role in the disassembly of B. subtilis biofilms and ylmE or racX mutants (in which the racemases YlmE or RacX are absent) show a delay in pellicle disruption [I. Kolodkin et al. Science (2010) 328:627-629]. The racX encoding gene is part of a bicistronic operon in which the first gene (pbpE) codes for a Penicillin-Binding Protein, the PBP4* whose function is not characterized. Our studies aim to delete the complete pbpE-racX operon and compare the phenotypes of mutants and parental strains ATCC21332 or ATCC6051 in standing cultures. The substrate specificity of the purified RacX racemase is currently under investigation as well as the functional characterization of PBP4*, a protein possessing a lipocalin-like domain. [less ▲]

BACKGROUND: In 2001, the World Health Organization (WHO) has recommended the use of artemisinin-based combination therapy (ACT) as the first-line treatment of uncomplicated malaria cases, as monotherapies had become ineffective in many parts of the world. As a result, the Democratic Republic of Congo (DRC) withdrew chloroquine (CQ) from its malaria treatment policy in 2002 and an artesunate (AS)-amodiaquine (AQ) combination became the ACT of choice in DRC in 2005. AQ-resistance (AQR) has been reported in several parts of the world and mutations in codons 72-76 of the Plasmodium falciparum chloroquine-resistance transporter (pfcrt) gene have been strongly correlated with resistance, especially mutations encoding the SVMNT haplotype. This haplotype was first identified in Southeast Asia and South America but was recently reported in two African countries neighbouring DRC. These facts raised two questions: the first about the evolution of CQ resistance (CQR) in DRC and the second about the presence of the SVMNT haplotype, which would compromise the use of AQ as a partner drug for ACT. METHODS: A total of 213 thick blood films were randomly collected in 2010 from a paediatric clinic in Kinshasa, DRC. Microscopy controls and real-time polymerase chain reaction (RT-PCR) were performed for Plasmodium species identification. Haplotypes of the pfcrt gene were determined by sequencing. RESULTS: The K76T mutation was detected in 145 out of 198 P. falciparum-positive samples (73.2%).In these 145 resistant strains, only the CVIET haplotype was detected. CONCLUSIONS: This study is the first to assess the molecular markers of resistance to CQ and AQ after the introduction of ACT in DRC. The results suggest first that CQR is decreasing, as wild-type pfcrt haplotypes were found in only 26.8% of the samples and secondly that the SVMNT haplotype is not yet present in Kinshasa, suggesting that AQ remains valid as a partner drug for ACT in this region.

With the exception of the Johannesburg Stock Exchange, African stock markets are characterized, in their vast majority, by a marginal number of listed companies, low capitalization, low trading volume and low liquidity. These characteristics raise questions about the volatility, efficiency, optimal compensation risks to investors and, more generally, to the price adjustment speed to the information conveyed by the volume of transactions. The objective of this doctoral work is to study the behavior of African stock markets through volatility, price, return and volume of transactions in connection with the performance and volatility. Compared to the volatility modeling, the study shows that the EGARCH model is the most suitable process may be applied to the data of African stock markets for estimating and forecasting volatility. For efficiency, the study shows that only the market of South Africa seems to be informationally efficient in the weak form. The analysis of the risk-return relationship reveals that only less developed markets (except Botswana) show a positive and significant premium risk. Such a result means that the least developed African stock markets in the sample reach rewarded accordingly risks for investors. For asymmetry, the study shows that there is presence of leverage for all emerging markets, indicating that in these markets, the bad news has a greater impact on volatility than good news of the same magnitude. In contrast, for less developed markets, there is no leverage. With respect to the relationship between the volume of transactions, performance and volatility, the study shows that emerging African stock markets showed a more or less close to the behavior of other emerging and developed markets of the world in terms of leverage, contemporary positive relationship and causality between trading volume and performance on the one hand, and between trading volume and volatility, on the other hand. In contrast, for other less developed stock markets, the impact of volume on return and volatility is less noticeable. [less ▲]

Amongst other functions, cover crops are known to increase the stability of the soil structure. Commonly, their suppression is realized by using conventional tillage, but that it has been demonstrated to damage the soil structure, which directly impacts the soil water content. The proposed alternatives vary in terms of date, depth and type of tillage. As the soil water content is a major factor in agriculture, it is essential to better understand the influence of the cover crop management on its spatio-temporal distribution. Recent studies demonstrated the relevancy of the electrical resistivity tomography (ERT) to estimate the three-dimensional soil water content distribution. However, only a few of them were performed under field conditions. This study aims at (i) validating the use of the ERT method to estimate the soil water content distribution under field conditions (ii) quantifying the influence of cover crop management on the dynamic of soil water content along the growing season of a maize crop and on Belgian soil types. Three types of cover crop management content will be daily monitored: strip tillage, spring tillage and winter tillage. In order to assess the impact of plants on the soil water distribution, an additional plot will be burned after winter tillage. ERT will be used on a surface of 2 m² for each cover crop management. The validation of the average soil water content will be attended by using Time Domain Reflectrometers (TDR) and suction cups. The water stock obtained by ERT will be validated by using data from a weather station for the estimation of the evapotranspiration and rainfall and minirhizotrons for the assessment of the root water uptake.

Cette étude examine la perception des tradipraticiens par les populations, afin d’envisager leur intégration dans les politiques de développement de Kisenso par des focus groupes en juillet 2013. 100% de participants reconnaissent l’existence de tradipraticiens et les avoir déjà consultés, 80% déclarent avoir expérimenté la guérison totale. Le recours au tradipraticien est justifié par l’efficacité des soins, le type de maladie, la compétence, la proximité et la possibilité de paiement à crédit. Pour 70% des participants, le tradipraticien doit améliorer les conditions d’hygiène dans la manipulation des produits. La quasi-totalité des tradipraticiens ne sont pas autorisés à fonctionner, dû notamment au coût d’actes administratifs pour l’obtention de l’autorisation et la peur de s’ouvrir aux intellectuels. 20% d’entre eux disent collaborer avec la biomédecine pour les soins de "mbasu", 20% se déclarent spécialistes en ostéologie, 20% dans les soins de "mbasu" et 60% disent tout soigner. Si l’on veut intégrer les tradipraticiens dans les politiques de développement local, on devra supprimer le coût d’actes administratifs, leur accorder des formations, intégrer les soins traditionnels dans les paquets d’activités et leur accorder le statut d’agent de l’Etat.
