Sub-Saharan African nations are highly dependent on the agricultural sector for livelihoods. South Africa and Nigeria depend on agriculture due to the availability of abundant land, labour and natural resources. According to the theory of comparative advantage a state exports the products that it has a comparative advantage in and imports those where it does not have a comparative advantage. This is facilitated by international trade. International trade is defined as trade among nations that enables a nation to buy certain products that it cannot produce from other nations at a cheaper rate. Furthermore, it is expected that every sovereign state would be able to provide not only food and water but also good access to sufficient food and water to its people. Section 27.1b of Chapter 2 of the South African Constitution of 1996 and Article 16 of Nigeria’s Constitution of 1999 enshrine this provision. A number of factors impact food security. The first is international trade. This is spelt out in the World Trade Organization (WTO) Agreement on Agriculture (AoA). The agreement establishing the WTO is commonly known as the “Marrakesh Agreement.” It was signed in Marrakesh, Morocco on the 15th of April, 1994, at the end of the Uruguay Round of Multiple Trade Negotiations. The AoA consists of three pillars: market access, export subsidies and domestic support .Market access requires all parties to the AoA to remove non-tariff barriers which comprise of import quotas and restrictions and convert them to tariffs; a process known as ‘tariffication’. States are also obliged to reduce export subsidies at the same time as increasing their imports. Domestic support, states are to remove subsidy it gives to its people a process that increases the price of goods. Another factor is trade liberalization. This study examines the effects of WTO agricultural trade liberalization on food security and the mechanisms available to address this issue. It focuses on the food security implications of the WTO AoA and asserts that the AoA favours agricultural producers in developed countries. The study seeks to ascertain the extent to which the realization of the objectives of the agreement will promote food security by looking into the abovementioned three pillars and their relationship with food security. / Thesis (LL.M.)-University of KwaZulu-Natal, Durban, 2013.

This thesis deals with the integration of firms into export markets when trade barriers decrease. It consists in three chapters.The first chapter focuses on how cross-industry differences in factor intensities and within-industry differences in firm productivity shape the response of the extensive (the decision to export) and the intensive (the exported volumes) margin of export. The context of the analysis is the entry of Turkey into the European Customs Union in 1996. Results suggest that the extensive margin reacted more in labor-intensive sectors.In the second chapter we use a gravity approach to analyze how the decrease in tariffs promoted during the '90s by the Uruguay Round multilateral agreement affected trade margins for French firms. We find that the tariffs significantly affect trade only through the extensive margin. The third chapter describes the dynamic of firms' export to different countries and uncovers eleven new stylized facts on firm-level trade. / Esta tesis trata de la integración de las impresas en los mercados internacionales cuando las barreras al comercio bajan. El primer capitulo analiza como las diferencias de la intensidad de los factores entre las industrias y de la productividad de las impresas en cada industria determinan la respuesta del margen extenso (la decisión de exportar) y intensivo (los volúmenes exportados) de cada impresa. El contexto de este análisis es la entrada de la Turquía en la Unión Aduanera Europea en el 1996. Los resultados indican que el margen extenso reacciona más en los sectores más intensivos en mano de obra.En el segundo capitulo utilizamos una ecuación gravitacional para analizar como el decrecimiento de las tarifas obtenida en los '90s gracias al "Uruguay Round" ha afectado los márgenes del comercio de las impresas Francesas. Descubrimos que las tarifas afectan de una manera significativa solo el margen extenso.El tercero capitulo describe la dinámica del exporte de las impresas en distintos Piases y revela once nuevos hechos estilizados sobre el comercio de las empresas.

As discussões sobre as relações entre o Acordo TRIPS e a Convenção sobre a Diversidade Biológica (CDB) encontram-se na agenda internacional desde a realização da IV Conferência Ministerial da Organização Mundial do Comércio, ocorrida em novembro de 2001, em Doha no Catar. Apesar da considerável atenção que o tema tem recebido nos fóruns internacionais, o debate sobre o tratamento adequado da questão persiste sem solução. A presente tese apresenta uma abrangente análise das conexões que existem entre a proteção dos direitos de propriedade intelectual e a conservação da diversidade biológica. Além disso, a partir de uma análise de conceitos de propriedade intelectual como patentes, indicações geográficas, transferência de tecnologia e propriedade comunitária de conhecimentos tradicionais, destacam-se elementos necessários para o uso sustentável e conservação dos recursos biológicos. / The goal of establishing a positive relationship between the TRIPS Agreement and the Convention on Biological Diversity has been on the international agenda since the fourth Ministerial Conference of the World Trade Organization (WTO), in Doha, Qatar, in November 2001. Despite a considerable amount of attention in the international forums, the debate about the appropriate parameter of this relationship persists without resolution. This thesis provides a comprehensive analysis of the relationship between the protection of intellectual property rights and the conservation of biological diversity. Furthermore, that upon analysis of concepts of intellectual property such as patents, geographical indications, technology transfer and communal property over traditional knowledge, issues are identified to support the conservation and sustainable use of the biological resources.

Le but de la recherche est d'identifier la stratégie de l'Union européenne dans le cadre du règlement des différends à l'OMC et de déterminer le rôle que jouent les différends commerciaux internationaux au niveau interne communautaire. La spécificité de la participation de l'UE par rapport aux autres Etats membres de l'OMC et les raisons de sa participation sont étudiées plus particulièrement dans le cadre d'une réflexion sur la manière dont les litiges internationaux s'inscrivent dans sa politique externe. Nous analysons en outre l'apport des litiges de l'Union européenne dans le développement du droit international. Le travail est articulé autour de deux axes qui contribuent à l'étude de la cohérence de la stratégie de l'UE au sein de l'ORD.Les politiques de l'Union européenne sont fréquemment mises en cause devant l'Organe de règlement des différends de l'OMC. L'UE utilise les litiges commerciaux internationaux comme un instrument de sa politique commercial, notamment dans le but de promouvoir à l'international ses valeurs non-commerciales et les intérêts primordiaux, ainsi que pour défendre son acquis historique selon les lignes directrices de ses politiques. Ces ambitions de l'Union expliquent la particularité de ses litiges commerciaux internationaux. La première partie analyse la nature spécifique des litiges commerciaux internationaux de l'UE et vise à répondre à la question de savoir par quels moyens l'UE essaye d'imposer son expérience de libéralisation des échanges au niveau international (Partie I).Dans la seconde partie nous procédons à l'analyse du choix des modalités de règlement de différends par l'Union en fonction de différents critères. Ainsi, le mode de règlement d'un différend dépend des parties impliquées dans le conflit et des enjeux en cause. En outre, nous examinons si les conditions institutionnelles de sa participation au règlement des différends commerciaux et les mécanismes spéciaux de la PCC existant au sein de l'UE sont compatibles avec les exigences du droit de l'OMC, et s'ils sont par conséquent « rentables » pour la défense efficace des intérêts de l'UE tant commerciaux que non commerciaux (Partie II). / The main purpose of the research is to identify the European Union's strategy in the Dispute Settlement Body of the WTO and to determine the role that international trade disputes play on the European level. Particularly, the EU participation specificity, compared to other Members of the WTO and the reasons for its involvement, are examined in the frame of an analysis on the manner in which international disputes inscribe into its external policy. We also analyze the EU disputes contribution to the development of international law. The research articulates around two main parts which contribute to the study of coherence of the EU strategy in the DSB.EU policies are frequently attacked in front of the DSB. The EU uses recourse to international trade disputes as an instrument to promote to the international level its non trade values and essential interests and to defend its historical acquis according to main directions of its policies. These EU ambitions explain the specificity of its international trade disputes. The first part of the research analyses the particular nature of international trade disputes of the EU and intends to answer the question to know by what means the EU tries to impose its own experience of trade liberalization onto international level (Part I).In the second part we are analyzing the EU choice of modes of dispute settlement depending on different criteria. So, the dispute settlement means depends on the parties to the conflict and the stakes of the dispute. We also examine if institutional conditions for its participation to settlement of international trade disputes and special mechanisms of Common Commercial Policy existing in the EU are compliant with WTO law requirements, and if they are consequently profitable for efficient defense of the EU trade and non trade interests (Part II).

Le Système de préférences généralisées (SPG) correspond à des réductions de droits de douane offertes par des sujets de droit international pubic « développés » aux pays en développement (PED). De manière générale, la conditionnalité est, quant à elle, un mécanisme qui permet de lier l’établissement, l’approfondissement, ou le maintien d’une situation juridique à la réalisation de conditions par un ou des bénéficiaire(s). Lorsque ce mécanisme est qualifié de « politique », ses conditions ont trait à la manière de gouverner et/ou à l’orientation des affaires publiques d’un sujet de droit international public. Le SPG de l’Union européenne (UE) contient plusieurs formes de conditionnalités qui agissent dans différents domaines des politiques publiques des PED bénéficiant de cette réduction douanière. L’intérêt de cette étude est d’aborder le SPG conditionné de l’UE dans le cadre de la construction de cette organisation internationale sui generis et comme révélateur d’une conception qui lui est particulière des relations internationales pour le développement. Par un effet miroir propre à chaque acte juridique, dans quelle mesure cet acte autonome reflète-t-il certaines caractéristiques de l’Union, une certaine identité de l’Union ? Le SPG conditionné de l’UE est tout d’abord un vecteur certain d’une identité européenne du développement en raison du caractère unilatéral de sa définition et de la relative uniformité de sa mise en œuvre. Cependant, celui-ci constitue un vecteur limité et ambivalent. Limité, tout d’abord, car le SPG est un acte secondaire au sein de la politique commerciale et car sa conditionnalité politique n’est pas reproduite dans d’autres actes des relations extérieures de l’Union. Ambivalent, ensuite, car cet acte autonome peut paraître illicite dans les relations commerciales internationales, tout en renouvelant le concept de développement par le commerce au sein de l’Organisation mondiale du commerce (OMC). / A Generalized System of Preferences (GSP) is a reduction in custom fees on exports from « developing » subjects of public international law to « developed » countries. As a general rule, conditionality is a tool used to establish, deepen or maintain a legal situation conditioned by specific behavior from it’s beneficiary(ies). This tool is qualified as « political » when it conditions governing tools and/or the public policy of a subject of public international law. The European Union’s GSP has several forms of conditionality which deal with the public of policy of the developing countries benefiting from reduced custom fees. This work aims to study the EU’s conditioned GSP in the context of this sui generis international organization’s construction and as evidence of a EU-specific conception of international relations for development. As each legal tool reflects it’s creator, how does this act reveal certain characteristics of the EU or even aspects of the EU’s identity ? The EU’s conditioned GSP is an expression of European identity as it is defined unilaterally and applied with relative uniformity. However, this expression is limited and ambivalent. First of all, limited, because the GSP is a secondary act within EU commercial policy and it’s political conditionality is not found in other elements of the EU’s foreign relations. Secondly, ambivalent, because this GSP can seem illegal in the context of international commercial relations, all the while renewing the concept of development-through-trade within the World Trade Organization (WTO).

A Reasonable Doubt is the act by which the Customs communicates the importer that doubts that this has declared the customs value in compliance with the valuation rules properly, requiring information and documentation necessary to verify that they have properly followed the rules valuation. In this article as we explore the conceptual and procedural aspects of management prerogative, we will try to find the limits to their exercise from the time, space and material point of view consistently (in concordance) with the rights and obligations of taxpayers. / Una Duda Razonable es el acto a través del cual la Aduana comunica al importador que duda que éste haya declarado el valor en aduanas cumpliendo las reglas de valoración adecuadamente, requiriendo la información y documentación que sea necesaria para verificar que se han cumplido adecuadamente con las reglas de valoración. En este artículo mientras analizamos los aspectos conceptuales y procedimentales de esta prerrogativa de la administración, trataremos de encontrar los límites a su ejercicio desde el punto de vista temporal, espacial y material en concordancia con los derechos y obligaciones de los contribuyentes.

This study investigates the impact of trade liberalization on food security at both national and rural household levels in Mozambique. Three periods are covered at national level: before trade reforms (1975-1986), after reforms under IMF/WB’s (International Monetary Fund/World Bank’s) period (1987-1994), and after reforms under IMF/WB/WTO’s (World Trade Organization’s) period (1995-2014). The researcher adopted the conceptual framework developed by the FAO (2003:235) according to which a country’s food security status can be influenced by diverse factors, including trade liberalization, through changes in relative prices, in quantities produced and consumed, and in trade volumes. At national level, the evidence suggests that trade liberalization’s impact on food security is both positive and negative. At rural household level, the empirical findings suggest that trade liberalization has no significant impact, either positive or negative, on households’ food security due mainly to poor infrastructure, households’ high dependence on subsistence farming and their lack of purchasing power. / Development Studies / M.A. (Development Studies)
