Sécurité alimentaire et libéralisation agricole / Food security and agricultural liberalization

Diagne, Rokhaya 22 November 2013 (has links)
La sécurité alimentaire définie comme l’accès à tous à une nourriture saine et suffisante, comporte quatre dimensions : les disponibilités, l’accessibilité, l’utilisation et la stabilité. Soumis à l’ajustement structurel depuis la fin des années 1980, les pays en développement (PED) ont procédé à une libéralisation agricole et à une ouverture commerciale, tandis que les pays développés maintiennent leur protectionnisme agricole. Le premier objectif de la thèse est d’analyser les méfaits d’une libéralisation agricole mal menée et inadaptée à travers les bilans des réformes agricoles au Sénégal et de la crise alimentaire de 2008. Les causes profondes de cette crise sont la financiarisation des marchés agricoles, leur dérégulation, et l’inefficacité des politiques agricoles et alimentaires dans les PED. La sécurité alimentaire est un but affiché par tous les pays mais faudrait-il être en mesure de la quantifier? Notre seconde ambition est de construire un indice synthétique de sécurité alimentaire grâce à une analyse en composante principale sur un échantillon de 125 pays en 2005 et 2009. Le résultat principal est que le score des pays développés s’est amélioré durant cette période, alors que celui des pays à faible revenu et à déficit vivrier s’est dégradé. Ainsi, les inégalités alimentaires entre les pays développés et ceux pauvres se sont accrues. Une classification hiérarchique ascendante par la méthode de Ward a permis de distinguer quatre situations alimentaires : la satiété, la sécurité, l’équilibre, et l’insécurité alimentaire. Elle a montré que la dépendance aux importations et les prix alimentaires avaient plus d’impact sur l’insécurité alimentaire que les revenus. / Defined as access to all a healthy and sufficient food, food security has four components: availability, access, utilization and stability. Subjected to structural adjustment since the late 1980s, developing countries (DCs) have conducted an agricultural liberalization and trade opening, while developed countries maintain their agricultural protectionism (domestic support and export subsidies). The first objective is to analyze the misdeeds of agricultural liberalization poorly conducted and inadequate through the agricultural reforms in Senegal and the 2008 food crisis. The root causes of this crisis reside more in the financialization of agricultural markets, the deregulation and inefficient agricultural and food policies in developing countries. Food security is a stated goal for all countries, but would it be able to quantify it? Indeed, it was conceptualized but its multidimensional nature made it difficult to quantify. Our second goal is to build a composite indicator of food security through a principal component analysis (PCA) on a sample of 125 countries in 2005 and 2009. The main result is that the score of the developed countries has improved during this period, while that of low-income food deficit deteriorated. We can deduce that due to food crisis, food inequalities between developed and poor countries have increased. In addition, a hierarchical cluster analysis (HCA) with Ward's method was also performed and showed four different food situations in our sample: food satiety, food security, food balance, food insecurity. It also highlighted the fact that the dependence on food imports and food prices had more impact on food insecurity as income.

ANALÝZA PŘÍČIN, DŮSLEDKŮ A ZPŮSOBŮ ŘEŠENÍ POTRAVINOVÉ KRIZE / Analysis of the Food Crisis: Causes, Consequences and Solutions

Ptáčník, Martin January 2011 (has links)
The thesis brings a comprehensive analysis of the food crisis of recent years. There was a dramatic increase in staple food prices in 2007-2008 and 2010-2011 which combined with persistent poverty is a serious problem for many millions of people. The objective of the thesis is to analyze the causes of this phenomenon. There are also examined socio-economic effects of rising global food prices on the quality of life in developing countries. In this sense, research is carried out whether the appropriate means helped to solve the food crisis and there are also suggested other options to address the current situation in order to reduce hunger and undernutrition in the world and avoid other people fall into poverty. Research is conducted using the method of observation, causal analysis and synthesis.

"They Come, but They Don't Spend as Much Money": Livelihoods, Dietary Diversity, Food Security, and Nutritional Status in Two Roatan Communities in the Wake of Global Crises in Food Prices and Finance

Brown, Racine Marcus 01 January 2013 (has links)
ABSTRACT This dissertation explores the associations between recent global crises in staple food prices and finance and the following aspects of life in two communities on the island of Roatàn, Islas de La Bahia (Bay Islands), Honduras: household livelihoods; food commoditization; dietary diversity; food security; and nutritional status. The aims of this study are: ) assess the geographic and economic source(s) of foods consumed by two different communities on Roatàn; b) discover how the most recent economic and food crises have affected foodways and nutrition on Roatàn; c) assess how these crises have affected economic growth of the tourism sector on Roatàn. The two study sites are the towns of West End and Punta Gorda, towns with different histories and different trajectories in the recent tourism boom on the island. West End is a small village located at the western edge of Roatàn and has experienced a steady growth in tourism since the 1980s. Tourism in Punta Gorda has grown noticeably since the cruise ships started making ports of call to the island in the early Twenty First Century. The theoretical perspective of this study is an amalgamation of bioculturalism and political ecology, as the strengths of these two approaches are complementary. In this case, the project is biocultural in that it investigates the linkages between global and local level political economic processes, cultural traits, and biological health indicators. The project is political ecological because it addresses the intersection of the political economic and the ecological by describing changing land use and subsistence patterns in the context of a shift in the local economy to tourism based wage labor. In terms of methodology, this project employs a mixed methods approach which triangulates qualitative and quantitative data collected through a variety of means. Participant observation, the detailed observation of and participation in social events, special occasions, work activities, and other events of daily life underpins the entire methodology. Other qualitative methods include informal interviews and semi-structured interviews. Quantitative methods include surveys to assess dietary diversity and food security and anthropometric measurements such as weight and height that serve as a baseline for calculating nutritional indices such as body mass index and body fat percentage. Overall, the sample is split about evenly in primary household livelihoods between formal tourism work, small scale enterprise, and the category of shipping, seafood, and office work. At the community level, West End is more heavily involved in tourism work and Punta Gorda is more heavily involved in shipping, seafood, and office work. Both communities have a strong component of small scale enterprise, including artisanal fishermen, water taxi operators, and vendors of food and souvenirs. Both communities are imbedded in a highly commoditized food system, with all households in the sample buying the majority of their food rather than growing or catching it. The two main effects of this circumstance are that dietary diversity and food security are associated with income level and that the current trend of rising food prices, which is associated with a trend of rising fuel prices, is making certain foods harder for some households to obtain. In general, the sample has a mode of medium dietary diversity and moderate food insecurity. Significant factors influencing dietary diversity are community, occupational group, income group, and how frequently a household does artisanal fishing. Significant factors in food security include occupational group and income group. For adult respondents, obesity is a pervasive problem and is evident in results for body mass index, body fat percentage, and waste to hip ratio, as well as in frequent discourse about diabetes and hypertension. Child measurement results show no problem with stunting or wasting and a lower prevalence of obesity than in adults. While the nutritional picture in these two communities is not as dire as it is in many Central American examples, there is room for improvement. Recommendations stemming from this project include: communities gardens to bolster access to a more diverse diet; a cooperative based on fishing of an invasive marine species in order to control its population an provide a sustainable livelihood for artisanal fishermen; and a tourism customer service course to make local people more competitive for a wider array of tourism jobs.

Důvody vzniku potravinové krize v letech 2007-2008 / Reasons why there was a food crisis in 2007 and 2008

Albertová, Jana January 2008 (has links)
This diploma thesis "Reasons why there was a food crisis in 2007 and 2008" summarizes and analyzes to what extent contributed particular factors to food crises all around the world in 2007 and 2008. Media and some well known international organizations believed that the main factors that caused last food crises were bio-fuels and significantly increased demand from China and India. This diploma thesis summarizes all main factors and comes to conclusion that the main factor that should be eliminated as soon as possoble is the problem with global climatic changes. Several international organizations have discussed this issue on international and global level for several years so let us hope we will not only discuss but we will do some active and concrete steps to solve this global problem. Of course the other factors need to be eliminated or at least moderated in the future as well. None of the crises occurs because of some concrete factor. It is always set of reasons that have caused some global problem.

Ecosystemic supply chain : a research and development centre for urban agriculture

Van Deventer, Thomas 30 November 2011 (has links)
With our ever increasing global population it will be necessary for dense urban environments to develop methods of farming locally. Not only will urban agriculture be beneficial in aiding in the solution of this growing populations need for food production, but it can help to reconnect us to our food and their processes. This dissertation explores the education and reconnection of the public with the food production cycle through the experience of building integrated agriculture, vermiculture and aquaponic systems (cultivating plants and fish symbiotically). Pretoria’s Apies River is an ideal location for the establishment of a research facility of urban ecosystemic food production. The proposed urban agriculture program will allow for hands on research and development of emerging methods and technologies related to farming in the city environment while providing a platform for public education through interaction&inspiration. / Dissertation (MArch(Prof))--University of Pretoria, 2011. / Architecture / unrestricted

Re-spatializing food security: Chinese agri-investments in Australia

Böhme, Michaela 31 January 2022 (has links)
Since the release of the report “Who will feed China?”, published in 1994 by the private environmental research organization World Watch Institute, there have been widespread concerns over China’s ability to feed its population in a sustainable and long-term manner. Against a backdrop of continued economic growth and changing consumption patterns, the World Watch Report predicted that China1 would need to rely on massive food imports, eventually leading to food scarcity on global food markets and a food crisis of global magnitude.

F. A. Hayek et Herbert A. Simon : la contribution de deux approches par la complexité à l'élaboration d'un corps de connaissances et d'outils utiles dans l'analyse et la prévention des "poly-crises" alimentaires. L'exemple de la crise alimentaire de 2007-2008 / F. A. Hayek and Herbert A. Simon : two approaches face to complexity. Lessons for analysis and prevention of poly-food crisis. The case of the 2007-2008 food crisis

Desbois, Jean-Marc 24 November 2016 (has links)
Entre avril et juin 2008, le prix des commodités (blé, maïs, riz) a atteint un niveau impressionnant, mais pas exceptionnel. Les populations de 48 pays ont été affectées par une sévère sous-alimentation. La plupart d’entre eux avait déjà été affaiblie par des conflits et des catastrophes naturelles inhabituelles et dramatiques. Ces facteurs ont souvent interagi pour aggraver la situation. Pourtant, si la crise de 2007-2008 a été un «problème extraordinaire», c’est aussi parce que la connaissance scientifique «normale» a échoué face à la complexité de la «poly-crises» alimentaire (Morin, 2011). En réponse, nous avons conçu un cadre épistémologique, méthodologique, et technique, à partir de deux approches face à la complexité, celles de Hayek (1899-1992) et de Simon (1916-2001), avec un objectif, satisfaire au critère de cumulativité, un reproche traditionnellement adressé à ce type d’approche. Ce travail a produit deux enseignements. Premièrement, les fondements épistémologiques de la production de la connaissance en économie doivent être révisés en environnement complexe et incertain: 1) du certain/de l’objectif vers l’incertain/le subjectif; 2) de la prédiction exacte vers la conception; 3) de la causalité linéaire inappropriée, ou pire, menaçant la liberté individuelle, vers une causalité complexe. Deuxièmement, dans le processus d’adaptation, le rôle de la production et du partage de la connaissance «tacite» est central. Pour cette raison, le problème économique n’est plus un problème d’allocation des ressources. Il est de savoir comment des êtres humains aux capacités cognitives «limitées» computent et socialisent (Nonaka et alii, 1994, 2001) la connaissance et l’information disponibles, mais dispersées, pour la convertir en heuristiques ou patterns favorisant l’adaptation. Deux autres hypothèses les renforcent : 1) les dynamiques du changement s’enracinent «dans la pensée et la créativité des gens impliqués dans des situations complexes et dans leur capacité à restructurer leurs propres modèles d’interactions», (Ostrom, 2011) ; 2) l’altruisme réciproque (Simon, 1992, 1993) est un comportement rationnel qui peut être plus efficient dans les interactions sociales en environnement complexe que le comportement maximisateur ou égoïste. Ces résultats ont été synthétisés dans une interface que nous avons créée et qui a pris la forme d’une boucle de la connaissance à deux allèles, une pour la connaissance générique, l’autre, pour la tacite, qui, par récursion, produisent une méta-connaissance. Cette interface est à la fois ouverte et fermée et reflète ainsi la position défendue par Hayek et Simon pour qui la science économique est une «science frontière». Une part de la recherche est consacrée à la création d’outils, par exemple à un indicateur de perception de la contribution des facteurs au déclenchement et/ou à l’aggravation de la crise, à partir : 1) des allocutions des 138 Chefs d’État et de Gouvernement présents à la Conférence de Haut Niveau sur la Sécurité alimentaire mondiale (3-5 juin 2008) ; 2) des analyses des économistes, 3) des témoignages des gens qui ont subi la sous-nutrition ou la hausse des prix des denrées alimentaires (database IRIN). Nous proposons également une typologie actualisée des policy-mix mis en œuvre par 18 pays divisés en 3 groupes : des pays en développement, pour la plupart importateurs nets, sévèrement touchés par la crise et qui ont connu des «émeutes de la faim» (Égypte, Tunisie, Cameroun, Côte d’Ivoire, Sénégal, Mauritanie, Haïti, Bangladesh) ; des pays Membres du groupe de Cairns ayant connu soit des «émeutes de la faim», soit des désordres sociaux (Indonésie, Philippines, Thaïlande, Afrique du Sud) ; enfin, des pays ayant adopté des restrictions et/ou prohibitions aux exportations (Chine, Inde, Indonésie, Égypte, Cambodge, Ukraine, Vietnam) [...]. / Over the April-June 2008 period, prices of the commodities such as wheat, maize, rice and vegetable oils, reached impressive yet not exceptional peaks. By contrast, the populations of 48 countries were stricken by severe under nutrition. Most of them had already been weakened not only by conflicts, social disorders, dramatic and unusual climatic and natural disasters, but also by outbreaks, epizooties, and population displacements. In some cases, all these factors together played a significant role in the worsening situation. However, another important reason could be advanced to explain why the 2008 food crisis was an “extraordinary problem”. This one is that “normal” scientific knowledge was defeated by the complexity of what it appears now as a food “poly-crises” (Morin, 2011). We answered by designing an epistemological, methodological, and technical knowledge base from two very different and alternative economics approaches of facing complexity. The first is the Hayekian approach (1899-1992), and the second, the Simonian approach (1916-2001). The research intends to fulfill cumulativity criteria, traditionally difficult to satisfy with the ones of complexity. From the following analysis we mostly learned two things. First, epistemological grounds of economics needed to be broken in complex environment(s): 1) from certainty/objectivity to uncertainty/subjectivity, 2) from accurate prediction to design, 3) from linear causality deemed inappropriate or, worse, threatening people freedoms, to complex causality. Second, in the adaptation process, the role of “tacit” knowledge production and sharing is central. For that reason, the core of economics problem is not allocation of resources anymore. Now, the main problem for humans whose cognitive capacity are “bounded” is to compute, to “socialize” (Nonaka et alii, 1994, 2001), available but dispersed information and knowledge and to converse them into heuristics or patterns allowing the adaptation to complex and uncertain environment(s). Two others auxiliary hypotheses –E. Ostrom (2011) will endorse them later- can be drawn from that preliminary work: 1) the dynamics of change rooted “in the thinking and in the creativity of people involved in complex situations and their capacity to restructure their own models for interactions”, 2) reciprocal altruism (Simon, 1992, 1993) is a rational behavior which can be more effective in/for the social interactions in complex environment(s) than maximizing or selfish behavior. To present preliminary results in an effective way, we created a very simple interface scheme. It takes the form of a three-dimensional knowledge loop with two strands, “generic” and “tacit” knowledge connected between themselves to produce by recursion a meta-knowledge. We made the choice of the interface because it reflects with the most accuracy the position defended by Hayek and Simon which is that economics is a frontier science. Moreover, the interface has the advantage of being both open and closed. A part of the research is more specifically dedicated to design tools increasing the understanding of the “polyfood” crises. We elaborated a three-level indicator with: 1) perceptions of the contribution of each factor to the outbreak and the worsening of the situation; 2) contributions of actors to the explanation of the food crisis proposed in 2008. It was developed from: 1) a case study comparing and contrasting explanations proposed a) in their statements by 138 Heads of State and Government attended the High Level Conference on World Food Security (3-5 June 2008), b) in their analyses by economists, c) in their testimonies by people hit by under nutrition/rising food prices (database IRIN); 2) a new and more updated typology focused on the responses addressed by 18 countries split into 3 groups [...].
