    Patterns and determinants of urban chicken consumption in Haiti and Cameroon: similar contexts, differentiated prospects

    Since the beginning of 2000s, in order to let poor people accede to meat consumption, several African and Caribbean countries have opened their domestic chicken market to foreign imports, by reducing import tariffs. Thus imported frozen pieces of chicken from the European Union or America compete with local chicken meat, causing the collapse of many poultry husbandry and the loss of many jobs in the local chicken food chain. In order to highlight the determinants of urban consumer’s choice relative to chicken types, and assess the opportunity for local chicken to restore its market share, investigations have been done in 2005 in Yaoundé (Cameroon) and in 2006 in Port-au-Prince (Haiti) applied to 180 urban households in each country. While imported frozen pieces of chicken have almost entirely substituted for the local chicken which has already quite disappeared in Port-au-Prince, Yaoundé consumers still prefer the local flesh chicken to the imported ones, at least for particular uses.chicken, urban consumption, developing countries, globalization, Cameroon, Haiti

    Food sovereignty and agricultural trade policy commitments: How much leeway do West African nations have?

    Get PDF
    The 2008 food crisis has challenged the political legitimacy and economic efficiency of the liberalization of international agricultural trade. An alternative vision defended by the food sovereignty movement is that long-term food security cannot rely on dependency on food imports, but must be built on the development of domestic production with enough barrier protection to shelter it from world price fluctuations and unfair trading. The purpose of this paper is to look into whether the West African nations can achieve food sovereignty given their various trade commitments and other external constraints. The particularity of our approach is to combine a historical economic analysis with a political approach to food sovereignty and trade commitments. Our results suggest that external brakes on the development of food sovereignty policies are marginal, as the countries still have unused room for manoeuvre to protect their smallholder agriculture under the terms of draft World Trade Organization agreements and Economic Partnership Agreements and under the international financial institutions’ recommendations. Rather, the international environment seems to be instrumented by West African states that do not manage to secure a national political consensus to drive structural reforms deemed vital and further the food security of the urban populations over the marginalized rural populations. Recently, the regional integration process has made headway with a common agricultural support and protection policy project that could herald an internal political balance more conducive to food-producing agriculture.food sovereignty, West Africa, protection, agricultural policy, WTO negotiations

    Utilising agricultural tariff rate quotas as a development instrument

    Get PDF
    Tariff rate quotas (TRQs) were introduced as a new market access instrument in the Uruguay Round Agreement on Agriculture. The purpose of this paper is to examine the case for using this instrument to target improved market access for developing country agricultural exports, using the EU as a case study. The paper first identifies how TRQs relate to the EU's hierarchy of agricultural trade preferences under various preferential access arrangements. It then examines the extent to which developing countries have been able to make use of existing TRQ access to the EU market. Developing countries wanting improved market access for their agricultural exports have the choice of negotiating lower MFN tariffs, entering free trade agreements or regional integration schemes, seeking improved preferential access under Generalised System of Preferences schemes, or pressing for the introduction of preferential TRQs under the GATT's special and differential treatment provisions. The final section of the paper discusses the merits and drawbacks of each of these strategies.

    Evolution of urban chicken consumption in Southern countries: a comparison between Haiti and Cameroon

    Since the beginning of 2000s, in order to let poor people accede to meat consumption, several developing countries have opened their domestic chicken market to foreign imports, by reducing import tariffs. Thus local chicken meat competes with frozen pieces of chicken imported from the European Union or America, causing the loss of many jobs in the local chicken food chain. In order to highlight the determinants of urban consumer’s choice relative to chicken types, and assess the opportunity for local chicken to restore its market share, investigations have been done in 2005 and 2006, in Yaoundé (Cameroon) and at Port-au-Prince (Haiti) applied to 180 urban households in each country. While imported frozen pieces of chicken have almost entirely substituted for the local chicken which has already quite disappeared in Portau- Prince, Yaoundé consumers still prefer the local flesh chicken to the imported ones, at least for particular uses.Chicken, urban consumption, developing countries, globalisation, Cameroon, Haiti., Food Consumption/Nutrition/Food Safety,

    CO deficiency in galaxies of the Fornax cluster?

    Get PDF
    There is ample observational evidence that cluster galaxies are different from those in the field. Interaction with the hot intracluster medium affects the morphology of the galaxies, their gaseous content and possibly their star-formation activity. Tidal encounters between galaxies also play an important role. The atomic component has been investigated in detail for several clusters, among them our neighbor Virgo. With the Swedish-ESO 15 m telescope, we have observed in the 12CO(1-0) transition the 23 brightest spirals and lenticulars of the Formax cluster

    Analysis and Design of Finite Alphabet Iterative Decoders Robust to Faulty Hardware

    Full text link
    This paper addresses the problem of designing LDPC decoders robust to transient errors introduced by a faulty hardware. We assume that the faulty hardware introduces errors during the message passing updates and we propose a general framework for the definition of the message update faulty functions. Within this framework, we define symmetry conditions for the faulty functions, and derive two simple error models used in the analysis. With this analysis, we propose a new interpretation of the functional Density Evolution threshold previously introduced, and show its limitations in case of highly unreliable hardware. However, we show that under restricted decoder noise conditions, the functional threshold can be used to predict the convergence behavior of FAIDs under faulty hardware. In particular, we reveal the existence of robust and non-robust FAIDs and propose a framework for the design of robust decoders. We finally illustrate robust and non-robust decoders behaviors of finite length codes using Monte Carlo simulations.Comment: 30 pages, submitted to IEEE Transactions on Communication

    Trends in family labour, hired labour and contract work on French and Swiss crop farms: The role of agricultural policies

    Get PDF
    The objective of this article is to analyse the trends in on-farm labour use, including own family labour, hired labour and contract work, and to assess the factors driving their evolution in France and in Switzerland during 1990-2007. A particular attention is given to agricultural policies, namely the level and type of support. Results indicate that crop area payments discourage the different labour demands in both countries, while environment and investment payments favour contract and hired labour in France. Contract labour and family labour are substitute and hired labour and family labour are complement in France.farm labour, hired labour, contract work, policies, Agricultural and Food Policy, Farm Management, Land Economics/Use,
