Collective Marketing Arrangements for Geographically Differentiated Agricultural Products: Welfare Impacts and Policy Implications, May 2006

This paper examines the incentive of atomistic agricultural producers within a specific geographical region to differentiate and collectively market products. We develop a model that allows us to analyze the market and welfare effects of the main types of real-world producer organizations, using it to derive economic insights regarding the circumstances under which these organizations will evolve, and describing implications of the results obtained in the context of an ongoing debate between the European Union and United States. As the anticipated fixed costs of development and marketing increase and the anticipated size of the market falls, it becomes essential to increase the ability of the producer organization to control supply in order to ensure the coverage of fixed costs. Whenever a collective organization allows a market (with a new product) to exist that otherwise would not have existed there is an increase in societal welfare. Counterintuitively, stronger property right protection for producer organizations may be welfare enhancing even after a differentiated product has been developed. The reason for this somewhat paradoxical result is that legislation aimed at curtailing the market power of producer organizations may induce large technological distortions.

The emergence of biofuels and the co-movement between crude oil and agricultural prices

Biofuels are becoming an alternative to non-renewable energy sources but we know little about the economic mechanisms influencing their prices. This paper studies the interrelationships between the spot prices of oil and those of agricultural commodities used as biofuel feedstocks. Using daily data since 1988, we identify a co-movement after 2005 that does not appear for other food-related commodities and is not due to general economic variables. We also find traces of the co-movement in the prices of a large biofuel stock. The results amount to the first systematic piece of empirical evidence linking spot oil and agricultural markets via the emergence of biofuels.

Geology and correlation of the Mersin mélanges, southern Turkey

Our paper aims to give a thorough description of the infra-ophiolitic melanges associated with the Mersin ophiolite. We propose new regional correlations of the Mersin melanges with other melange-like units or similar series, located both in southern Turkey and adjacent regions. The palaeotectonic implications of the correlations are also discussed. The main results may be summarized as follows: the infra-ophiolitic melange is subdivided into two units, the Upper Cretaceous Sorgun ophiolitic melange and the Ladinian-Carnian Hacialani melange. The Mersin melanges, together with the Antalya and Mamonia domains, are represented by a series of exotic units now found south of the main Taurus range, and are characteristic of the South-Taurides Exotic Units. These melanges clearly show the mixed origin of the different blocks and broken formations. Some components have a Palaeotethyan origin and are characterized by Pennsylvanian and Lower to Middle Permian pelagic and slope deposits. These Palaeotethyan remnants, found exclusively in the Hacialani melange, were reworked as major olistostromes in the Neotethys basin during the Eo-Cimmerian orogenic event. Neotethyan elements are represented by Middle Triassic seamounts and by broken formations containing typical Neotethyan conodont faunas such as Metapolygnathus mersinensis Kozur & Moix and M. primitius s. s., both present in the latest Carnian interval, as well as the occurrence of the middle Norian Epigondolella praeslovakensis Kozur, Masset & Moix. Other elements are clearly derived from the former north Anatolian passive margin and are represented by Huglu-type series including the Upper Triassic syn-rift volcanic event. These sequences attributed to the Huglu-Pindos back-arc ocean were displaced southward during the Late Cretaceous obduction event. The Tauric elements are represented by Eo-Cimmerian flysch-like and molasse sequences intercalated in Neotethyan series. Additionally, some shallow-water blocks might be derived from the Bolkardag para-autochthonous and the Taurus-Beydaglari marginal sequences.

Economic Aspects of Agricultural and Food Biosecurity in the United States, March 2007

Concerns about biosecurity in the food system raise a variety of issues about how the system is presently organized, why it might be vulnerable, what one could reasonably do to better secure it, and the costs of doing so. After presenting some facts about US agriculture and food, this paper considers three economic aspects of the general problem. One is the global problem, or the way biosecurity measures can affect how countries relate to each other and the global consequences that result. Another is how to best manage the immediate aftermath of a realized threat in order to minimize damage. The third is how to seek to prevent realization of the threat. Some policy alternatives are also presented.

Welfare Impacts of Cross-Country Spillovers in Agricultural Research, 2007

The welfare implications of intellectual property protection (IPP) for private sector agricultural research are analyzed, focusing on the realistic cases in which countries provide different IPP levels, technology spills over across countries, and the public sector is involved in research. A model is developed to determine who benefits from, and who should pay for, the associated research. The paper contains some interesting results on the implications of a harmonization of IPP policies through multilateral agreements or via technology that allows research firms to prevent the copying of plants and animals that express traits that have emerged from their research.

Statistical Brief on the Agricultural Research of Cape Verde

The primary purpose of this brief is to provide various statistical and institutional details on the development and current status of the public agricultural research system in Cape Verde. This information has been collected and presented in a systematic way in order to inform and thereby improve research policy formulation with regard to the Cape Verdean NARS. Most importantly, these data are assembled and reported in a way that makes them directly comparable with the data presented in the other country briefs in this series. And because institutions take time to develop and there are often considerable lags in the agricultural research process, it is necessary for many analytical and policy purposes to have access to longer-run series of data. NARSs vary markedly in their institutional structure and these institutional aspects can have a substantial and direct effect on their research performance. To provide a basis for analysis and cross-country, over-time comparisons, the various research agencies in a country have been grouped into five general categories; government, semi-public, private, academic, and supranational. A description of these categories is provided in table 1.

National Adaptation Programme of Action on Climate Change - 2008 - 2012

The archipelago of Cape Verde is made up of ten islands and nine islets and is located between latitudes 14º 28' N and 17º 12' N and longitudes 22º 40' W and 25º 22' W. It is located approximately 500 km from the Senegal coast in West Africa (Figure 1). The islands are divided into two groups: Windward and Leeward. The Windward group is composed of the islands of Santo Antão, São Vicente, Santa Luzia, São Nicolau, Sal and Boavista; and the Leeward group is composed of the islands Maio, Santiago, Fogo and Brava. The archipelago has a total land surface of 4,033 km2 and an Economic Exclusive Zone (ZEE) that extends for approximately 734,000 km2. In general, the relief is very steep, culminating with high elevations (e.g. 2,829 m on Fogo and 1,979 m on Santo Antão). The surface area, geophysical configuration and geology vary greatly from one island to the next. Cape Verde, due to its geomorphology, has a dense and complex hydrographical network. However, there are no permanent water courses and temporary water courses run only during the rainy season. These temporary water courses drain quickly towards the main watersheds, where, unless captured by artificial means, continue rapidly to lower areas and to the sea. This applies equally to the flatter islands. The largest watershed is Rabil with an area of 199.2 km2. The watershed areas on other islands extend over less than 70 km2. Cape Verde is both a least developed country (LDC) and a small island development state (SIDS). In 2002, the population of Cape Verde was estimated at approximately 451,000, of whom 52% were women and 48% men. The population was growing at an average 2.4% per year, and the urban population was estimated at 53.7 %. Over the past 15 years, the Government has implemented a successful development strategy, leading to a sustained economic growth anchored on development of the private sector and the integration of Cape Verde into the world economy. During this period, the tertiary sector has become increasingly important, with strong growth in the tourism, transport, banking and trade sectors. Overall, the quality of life indicators show substantial improvements in almost all areas: housing conditions, access to drinking water and sanitation, use of modern energy in both lighting and cooking, access to health services and education. Despite these overall socio-economic successes, the primary sector has witnessed limited progress. Weak performance in the primary sector has had a severe negative impact on the incomes and poverty risks faced by rural workers1. Moreover, relative poverty has increased significantly during the past decade. The poverty profile shows that: (i) extreme poverty is mostly found in rural areas, although it has also increased in urban areas; (ii) poverty is more likely to occur when the head of the household is a woman; (iii) poverty increases with family size; (iv) education significantly affects poverty; (v) the predominantly agricultural islands of Santo Antão and Fogo have the highest poverty rates; (vi) unemployment affects the poor more than the nonpoor; (vii) agriculture and fisheries workers are more likely to be poor than those in other sectors. Therefore, the fight against poverty and income inequalities remains one of the greatest challenges for Cape Verde authorities. The various governments of Cape Verde over the last decade have demonstrated a commitment to improving governance, notably by encouraging a democratic culture that guarantees stability and democratic changes without conflicts. This democratic governance offers a space for a wider participation of citizens in public management and consolidates social cohesion. However, there are some remaining challenges related to democratic governance and the gains must be systematically monitored. Finally, it is worth emphasizing that the country’s insularity has stimulated a movement to decentralized governance, although social inequalities and contrasts from one island to the next constitute, at the same time, challenges and opportunities.

Contribution to the geology of Southern Turkey: new insights from the Mersin mélanges and from the Lycian and Antalya nappes

Abstract The study of fossil Tethyan continental margins implies the consideration of the oceanic domains to which they were connected. The advent of plate tectonics confirmed the importance of the detection of accretion-related mélanges. Ophiolitic mélanges are derived from both an upper ophiolitic obducting plate and a lower oceanic plate. Besides ophiolitic elements, the mélanges may incorporate parts of a magmatic arc and dismembered fragments of a passive continental margin. As the lower plate usually totally disappears during the obduction process, it can only be reconstructed from its elements found in the mélanges. Because of their key location at active margin boundaries, preserved accretion-related mélanges provide strong constraints on the geological evolution of former oceanic domains and their adjacent margins. The identification of Palaeotethyan remnants as accretionary series or reworked during the Late Triassic Eo-Cimmerian event, as well as the recognition of HugluPindos marginal sequences in southern Turkey and in the external Hellenides represent the main achievements of this work, making possible to establish new palaeogeographical correlations. The Mersin mélanges (Turkey), together with the Antalya and Mamonia (Cyprus) domains, are characterized by a series of exotic units found now south of the main Taurus range and compose the South-Taurides Exotic Units. The Mersin mélanges are subdivided in a Triassic and a Late Cretaceous unit. These units consist of the remnants of three major Tethyan oceans, the Palaeotethys, the Neotethys and the Huglu-Pindos. The definition and inventory of the Upper Antalya Nappes (Turkey) are still a matter of controversies and often conflicting interpretations. The recognition of Campanian radiolarians on top of the Kerner Gorge unit directly overlain by the Ordovician Seydi§ehir Fm. of the Tahtah Dag Nappe outlines a tectonic contact and demonstrates that the Upper Antalya Nappes system is composed of three different nappes, the Kerner Gorge, Bakirli and the Tahtah Dag nappes. Additionally, a limestone block in a doubtful tectonic position at the base of the Upper Antalya Nappes yielded for the first time two middle Viséan associations of foraminifers and problematic algae. The Tavas Nappe in the Lycian Nappes (Turkey) is classically divided into the Karadag, Teke Dere, Köycegiz and Haticeana units. As for the Mersin mélanges, the Tavas Nappe is highly composite and includes dismembered units belonging to the Palaeotethyan, Neotethyan and HugluPindos realms. The Karadag unit consists of a Gondwana-type platform succession ranging from the Late Devonian to the Late Triassic. It belongs to the Cimmerian Taurus terrane and was part of the northern passive margin of the Neotethys. The Teke Dere unit is composed of different parts of the Palaeotethyan succession including Late Carboniferous OIB-type basalts, Carboniferous MORB-type basalts, an Early Carboniferous siliciclastic series and a Middle Permian arc sequence. The microfauna and microflora identified in different horizons within the Teke Dere unit share strong biogeographical affinities with the northern Palaeotethyan borders. Kubergandian limestones in primary contact above the Early Carboniferous siliciclastics yielded a rich and diverse microfauna and microflora also identified in reworked cobbles within the Late Triassic Gevne Fm. of the Aladag unit (Turkey). The sedimentological evolution of the Köycegiz and Haticeana series is in many points similar to classical Pindos sequences. These series originated in the Huglu-Pindos Ocean along the northern passive margin of the Anatolian (Turkish transect) and Sitia-Pindos (Greek transect) terranes. Conglomerates at the base of the Lentas Unit in southern Crete (Greece) yielded a microfauna and microflora presenting also strong affinities with the northern borders of the Palaeotethys. This type of reworked sediments at the base of Pindos-like series would suggest a derivation from the Palaeotethyan active margin. -Résumé (French abstract) L'étude des marges continentales fossiles de l'espace téthysien implique d'étudier les domaines océaniques qui y étaient rattachés. Les progrès de la tectonique des plaques ont confirmé l'importance de la reconnaissance des mélanges d'accrétion. Les mélanges ophiolitiques dérivent d'une plaque supérieure ophiolitique qui obducte, et d'une plaque inférieure océanique. En plus d'éléments ophiolitiques, les mélanges peuvent aussi incorporer des parties d'un arc magmatique, ou des fragments d'une marge continentale passive. Comme la plaque inférieure disparaît généralement complètement durant le processus d'obduction, elle ne peut être reconstruite qu'au travers de ses éléments trouvés dans les mélanges. A cause de leur situation aux limites de marges actives, les mélanges d'accrétion bien préservés permettent de contraindre l'évolution géologique d'anciens océans et de leurs marges. L'identification de vestiges de la Paléotéthys en série d'accrétion ou remaniés lors de l'orogenèse éo-cimmérienne au Trias supérieur, ainsi que l'observation de séquences marginales de Huglu-Pinde en Turquie du sud et dans les Hellénides externes représentent les principaux résultats de ce travail, permettant d'établir de nouvelles corrélations paléogéographiques. Les mélanges de Mersin (Turquie), avec les domaines d'Antalya et de Mamonia (Chypre), sont caractérisés par des unités exotiques se trouvant au sud de la chaîne taurique, et forment les Unités Exotiques Sud-Tauriques. Les mélanges de Mersin sont subdivisés en une unité triasique, et une autre du Crétacé supérieur. Ces unités comprennent les reliques de trois principaux océans téthysiens, la Paléotéthys, la Néotéthys et Huglu-Pinde. L'inventaire et la définition des nappes supérieures d'Antalya (Turquie) sont encore matière à controverse et donne lieu à des interprétations conflictuelles. La découverte de radiolaires campaniens au sommet de l'unité de la Gorge de Kemer, directement recouverts par la formation ordovicienne de Seydisehir de la nappe du Tahtali Dag met en évidence un contact tectonique et démontre que les nappes supérieures sont composées de trois différentes nappes, celle de la Gorge de Kemer, celle du Bakirli et celle Tahtali Dag. De plus, un bloc de calcaire dont la position tectonique demeure incertaine à la base des nappes supérieures a fourni pour la première fois deux associations viséennes de foraminifères et d'algues problématiques. La nappe de Tavas dans les nappes lyciennes (Turquie) est séparée en unités du Karadag, du Teke Dere, de Köycegiz et d'Haticeana. Comme pour les mélanges de Mersin, la nappe de Tavas est composite et inclut des unités appartenant à la Paléotéthys, à la Néotéthys et à Huglu-Pinde. L'unité du Karadag est une plateforme carbonatée de type Gondwana se développant du Dévonien supérieur au Trias supérieur. Elle appartient au domaine cimmérien du Taurus et formait la marge nord de la Néotéthys. L'unité du Teke Dere est composée de différentes écailles paléotéthysiennes et inclut des basaltes d'île océanique du Carbonifère supérieur, des basaltes de ride océanique du Carbonifère, une série siliciclastique du Carbonifère supérieur et un arc du Permien moyen. Les microfaunes et -flores trouvées à différents niveaux de la série du Teke Dere partagent de fortes affinités paléogéographiques avec les marges nord de la Paléotéthys. Des calcaires du Kubergandien en contact primaire au-dessus de la série siliciclastique a donné de riches microfaunes et -flores, également identifiées dans des galets remaniés dans la formation de Gevne du Trias supérieur de l'Aladag. L'évolution sédimentologique des séries de Köycegiz et d'Haticeana sont très similaires aux séries classiques du Pinde. Ces séquences prennent leur racine dans l'océan de Huglu-Pinde, le long de la marge passive nord anatolienne (profil turc) et de la marge de Sitia-Pinde (profil grec). Des conglomérats à la base de l'unité de Lentas au sud de la Crète (Grèce) ont donné des microfaunes et flores partageant également de fortes similitudes avec les bordures nord de la Paléotéthys. Le type de sédiments remaniés à la base d'unités de type Pinde suggère une dérivation depuis la marge active de la Paléotéthys. -Résumé grand public (non-specialized abstract) Au début du 20ème siècle, Alfred Wegener bouleverse les croyances géologiques de l'époque et publie plusieurs articles sur la dérive ou la translation des continents. En utilisant des arguments géographiques (similarités des lignes de côte), paléontologiques (faunes et flores similaires) et climatiques (dépôts tropicaux et glaciaires), Wegener explique qu'il y a plusieurs millions d'années, les terres émergées actuelles ne devaient former qu'un seul et grand continent. La fin du 20ème siècle verra l'avènement de la théorie de la tectonique des plaques suite à la reconnaissance du cycle de Wilson, des rides médio-océaniques, des anomalies magnétiques dans les océans et des sutures océaniques qui représentent les reliques d'océans disparus. Le Cycle de Wilson se caractérise par une suite d'évènements géologiques majeurs pouvant se résumer de la manière suivante : (1) séparation d'un craton continental en deux parties, créant une limite de plaque divergente. C'est ce que l'on appelle un rift; (2) développement et croissance d'un océan entre ces deux blocs. Des roches magmatiques remontent à la surface de la terre et forment une chaîne de montagne sous-marine que l'on appelle ride médio-océanique ou dorsale. L'océan continue de se développer, et des sédiments se déposent à sa surface formant la suite ophiolitique ou trinité de Steinmann; (3) après une phase d'expansion plus ou moins longue, les conditions imposées aux limites des plaques à la surface de la terre changent, et l'océan se met à se refermer par disparition progressive (subduction) de sa croûte océanique sous une croûte continentale par exemple. Ceci crée une nouvelle limite de plaque, convergente cette fois; (4) la subduction de la plaque océanique sous la plaque continentale provoque une remontée de magma formant des chaînes volcaniques à la surface de la Terre ; (5) une fois que la plaque océanique a complètement disparu, les deux blocs préalablement séparés par l'océan font collision, formant ainsi une chaîne de montagne. Les chaînes de montagnes sont de manière générale formées par un empilement plus ou moins complexe de nappes. C'est au coeur de certaines de ces nappes que se trouvent les vestiges de l'océan disparu. Un des objectifs de ce travail était la recherche de ces vestiges dans le domaine téthysien de la Méditerranée orientale. Pour ce faire, nous avons parcourus une grande partie du sud de la Turquie, nous sommes allés à Chypre, dans le Sultanat d'Oman, en Iran, en Crète, et nous avons visités quelques îles grecques du Dodécanèse. La région de la Méditerranée orientale est une zone qui a été tectoniquement très active, et qui continue de l'être de nos jours par des phénomènes de subduction (ex. les volcans de Santorin), et par des mouvements coulissants entre des plaques continentales (ex. la faille nord-anatolienne) qui donnent régulièrement lieu à des tremblements de terre. Pour le géologue, la complexité de ces zones d'étude réside dans le fait que les chaînes de montagne actuelles ne contiennent en général pas seulement les restes d'un océan, mais bien de plusieurs bassins océaniques qui se sont succédés dans l'espace et dans le temps. Les nappes qui se trouvent au sud de la Turquie et dans le Dodécanèse forment un important jalon dans la chaîne alpine qui s'étend depuis les Alpes jusque dans l'Himalaya. L'idée d'un continuum au coeur de ce système se basait principalement sur l'âge des océans et sur la reconnaissance de similarités dans l'évolution des séries sédimentaires. La localisation des vestiges de la Paléotéthys ainsi que l'identification des séries sédimentaires ayant appartenu à l'océan de HugluPinde repris sous forme de nappes en Turquie et en Grèce sont cruciales pour permettre de bonnes corrélations locales et régionales. La reconnaissance, la compréhension et l'interprétation de ces séries sédimentaires permettront d'élaborer un modèle d'évolution géodynamique régional, s'appuyant sur des faits de terrains indiscutables, et prenant en compte les contraintes globales que ce genre d'exercice implique.
