La production essentiellement développée dans les zones sahéliennes s'est renforcée dans les zones sud pour profiter des complémentarités qu'offraient les activités cotonnières et céréalières. De plus, les camions utilisés pour transporter le coton sont venus renforcer un commerce transfrontalier de bétail déjà très ancien ayant aux productions des pays sahéliens de trouver des débouchés viables. En effet, pour ne pas retourner à vide, ces camions ont été utilisés pour transporter le bétail sans pour autant éliminer le convoyage à pied qui reste encore aujourd'hui très important. Traditionnellement confiné aux échanges de bovins sur-pieds et convoyés par camions selon un gradient intérieur littoral où le commerce de bétail satisfait une demande spécifique de viande et surtout d'abats telles que les peaux et les queues, le commerce transfrontalier de bétail est actuellement soumis à un questionnement important sur la compétitivité entre différentes options de commercialisation : exportation de bétail et/ou exportation de viandes/abats. En effet, dans la plupart des pays du CILSS, émerge une préférence pour la construction d'abattoirs aux fins d'exporter des carcasses de viandes. Les chantiers sont en cours, lorsqu'ils ne sont pas déjà achevés. C'est pour cette raison que le CILSS à travers le PRAPS a jugé nécessaire d'un côté, de regarder si les conditions sont réunies pour que ces investissements prospèrent, et de l'autre, d'analyser leurs répercussions sur le plan économique, social et même politique au niveau des pays visés par l'exportation de ces carcasses. C'est le travail qui a été confié à l'ILRI à qui le CILSS a demandé de se focaliser le long du corridor de commerce de bétail-viande Burkina Faso-Ghana

With this study, we try to understand the elements of the competitive matrix of cities based on the local development strategy, taking into account an analysis of São Paulo and Rio de Janeiro in 2014. Thus, it became a case study based on a qualitative research in order to find solutions on the raised problem situation. Competitiveness is a key factor in defining the strategies of companies and the way she wants to beat the competition. Widely competitive markets recorded strong economic, social, political and environmental development. However, the matrix is not a static tool, but dynamic depending on the actions of their agents.

S'appuyant sur l'observation d'un panel de marches de betail du Ferio, cette contribution montre qu'ils font preuve de discernement lors de la commercialisation de leur betail. Ils se fient davantage a leur environnement incertain et episodiquement aux opportunites de marches qu'ils n'exploitent pas efficacement du fait de l'existence de dysfonctionnements (type de rationalite, asymetrie d'information, contraintes sur l'entree - sortie dans l'activite). Dotes d'une rationalite contextuelle, ils usent de strategies adaptatives et interviennent sur les marches pour des motifs principalement de consommation, parfois d'investissement et de speculation.

Thus, this chapter seeks to cast the most appropriate interventions in the framework of the overall study, with the long-term goal of reducing livestock owners’ vulnerability and emergency aid dependency and enhancing their resilience. While not meant to provide an exhaustive and comprehensive description of all options available (which anyway is not possible given the large variation in conditions across study countries), this chapter covers the proven and more promising interventions and presents good practices for each.1 The vision for the future is that in pure grassland areas (Aridity Index, AI = 0.05–0.20), priority attention is on reducing vulnerability by rebalancing the ratio of land/livestock/people and maintaining productivity at levels that ...

This is not so simple for Sahelian pastoralists living in uncertainty and absence of contingent markets. Sahelian pastoralists use livestock markets but these markets don't systematically influence their production and marketing decisions. Based on the case of Senegalese Sahel, we use a spatial panel model to estimate the magnitude impacts of spatial and time factors on pastoral income generation. Then, we extent discussions to show that Sahelian livestock keepers alternate homo oeconomicus and bounded behaviours vis-à-vis the markets that they know well even if markets don't know much about them - and that is one reason it can be hard for a real structural transition. The problems of pastoral marketing systems are still examined from the perspectives of infrastructure buildings while it is also necessary to reduce transaction costs and ...

Yet these contexts exhibit unique challenges on both information supply and demand sides, which widen the gaps between research and policy-making. This paper reviews the constraints to evidence-based policy-making and identifies knowledge areas most suitable for building a persuasive narrative that capture the attention of busy decision-makers. These promising spaces for production of new data and methods focus on livestock contribution to the economy, trade, food security and resilience. The examples discussed show the potential of current and future research for leveraging synergistic interests from multiple actors and improving livestock policy interventions.
