Selected AbstractsExploring the impact of R&D and climate change on agricultural productivity growth: the case of Western Australia,AUSTRALIAN JOURNAL OF AGRICULTURAL & RESOURCE ECONOMICS, Issue 4 2010Ruhul A. Salim This article empirically examines the impact of R&D and climate change on the Western Australian Agricultural sector using standard time series econometrics. Based on historical data for the period of 1977,2005, the empirical results show that both R&D and climate change matter for long-run productivity growth. The long-run elasticity of total factor productivity (TFP) with respect to R&D expenditure is 0.497, while that of climate change is 0.506. There is a unidirectional causality running from R&D expenditure to TFP growth in both the short run and long run. Further, the variance decomposition and impulse response function confirm that a significant portion of output and productivity growth beyond the sample period is explained by R&D expenditure. These results justify the increase in R&D investment in the deteriorating climatic condition in the agricultural sector to improve the long-run prospects of productivity growth. [source] The Distribution of Subsidized Agricultural Credit in Brazil: Do Interest Groups Matter?DEVELOPMENT AND CHANGE, Issue 3 2001Steven M. Helfand This article examines the unequal distribution of credit and credit subsidies in the Brazilian agricultural sector from 1969 to 1990. Total credit subsidies exceeded US$ 40 billion in this period. The distribution across crops is studied econometrically. After controlling for area, the crops that benefited most had superior access to credit institutions, were tradeable, had high prices, and were not perennials. Proxies for collective action by crop were an unimportant determinant of credit policy, while a bias in favour of large producers was evident. Alternative explanations for this bias are discussed, including collective action by farm size and transaction costs in lending. [source] Sector Programme Approaches: Will They Work in Agriculture?DEVELOPMENT POLICY REVIEW, Issue 3 2001Mick Foster This article explores why sector-wide approaches, in which donor funds support a single sector plan under government leadership, have performed less well in agriculture than in the social sectors. Many problems stem from the more limited, more contested and shrinking role of the state in the agricultural sector. It is also argued that sector programmes have worked best where the key constraints on sector development are the responsibility of a single ministry, whereas agricultural development requires co-ordinated interventions across sectors. The sector approach may have a limited role in delivering better focused agricultural services, but fundamental policy questions need to be resolved first. This is more likely if support for reforms is channelled through central economic ministries and other bodies outside the agriculture ministry. [source] Diversified Agriculture, Land Use, and Agrofood Networks in Hawaii,ECONOMIC GEOGRAPHY, Issue 1 2002Krisnawati Suryanata Abstract: Agriculture dominated the culture and economy of Hawaii until the mid-twentieth century, but has since been in a prolonged state of decline. This article examines strategies in Hawaii's diversified agriculture that seek to revitalize its agrarian sector and the difficult challenges these efforts face within the globalized agrofood systems. Drawing from the actor-network perspective, this article suggests an alternative approach to developing Hawaii's diversified agriculture. Networks of social actors that include growers, processors, gourmet chefs, retailers, and consumers have been able to create viable diversified agriculture in spite of the globalized agrofood systems. The article then discusses how the politics of land use and land development could condition Hawaii's ability to build networks that are critical to the maintenance of a diversified agricultural sector. [source] POPULATION AND EMPLOYMENT CHANGES IN REGIONAL AUSTRALIAECONOMIC PAPERS: A JOURNAL OF APPLIED ECONOMICS AND POLICY, Issue 1 2007ANNE M. GARNETT Regional Australia has experienced significant changes in population and employment since the early 1990s. Evidence regarding these changes has often been anecdotal, with references in political and media spheres to a ,Sea Change' or ,Tree Change'. There has also been considerable public discussion about the effect that the structural changes and misfortunes within the agricultural sector have had on localities in rural regions. The purpose of this paper is to provide and analyse data on regional population and employment changes since the early 1990s. It will also examine the role that the agricultural sector may have had in these changes. This will provide a basis for informed debate and analysis of population changes in regional Australia and the causes and implications of these changes. [source] Understanding the costs of an environmentally ,friendly' common agricultural policy for the European Union1,ENVIRONMENTAL POLICY AND GOVERNANCE, Issue 1 2001Pamela M. Barnes Part of the bedrock of the European Union's (EU's) Environmental Policy is the principle that those who pollute the environment should pay for the cost of remedying the damage they cause (the polluter pays principle) (Article 174 para. 2 TEC ex Article 130r TEC). In addition environmental objectives must be integrated into all the sectoral policies of the European Union (Article 6 TEC ex Article 3c TEC). The Common Agricultural Policy's (CAP's) role at the centre of the EU's sectoral policies would appear to make it an ideal focus for implementing Article 6 of the Treaty establishing the European Community (TEC). If integration of environmental protection can be achieved in this central area of the EU's activities then a major source of environmental degradation could be overcome. However, if these requirements are applied to European agriculture the sector will face a budgetary and financial crisis of even greater magnitude than at the present time. Recent reforms of the CAP have been designed with the objective of achieving an agricultural sector that is moving towards sustainability. As this article argues the political, social and economic significance of the agriculture sector is such that national governments of the EU have repeatedly shied away from adopting the measures, which could significantly reduce the pollution from the sector. The proposals for reform made by the Agricultural Commissioner, Franz Fischler, were amended by the meeting of the European Council that took place in Berlin on 24/25 March 1999. These amendments substantially weakened the ambitions of the strategy for development of the EU, the ,Agenda 2000' adopted in 1997, for a number of reasons (CEC, 1997). This article examines the reasons for the disappointments with the amended reforms and speculates on the possible future path that may be taken to improve matters.

A strong European agricultural policy remains necessary after 2013, at the service of Europe's citizens and agricultural sector. However, in order to realise the vision embedded in the European agricultural model, the CAP will have to evolve. Beyond dealing with the negative consequences of the economic crisis, more attention should go to competitiveness and entrepreneurship. The functioning of the supply chain should be improved leading to a fairer distribution of costs and benefits. Producer organisations should be expanded and strengthened. Work is needed to put into practice the concept of green growth and to explore the synergy between the demand for public goods and the need for higher farm income. An improved system of direct support remains justified, to compensate for extra costs and to stabilise income. The CAP post-2013 should offer a strong EU framework, able to meet shared challenges, with clear objectives and sufficient funding. Within that framework, diversity is a fact, and regions should be able to deploy CAP policies and funds in a more flexible way to accommodate local needs and problems and to be able to react to changing circumstances. De par l'apparition de nouveaux défis, il est clair que les réalisations antérieures de la PAC ne peuvent être considérées comme acquises.Une politique agricole européenne forte, au service des citoyens et du secteur agricole de l'Europe, reste indispensable après 2013. Cependant, pour concrétiser la vision comprise dans le modèle agricole européen, la PAC devra évoluer. Au-delà du traitement des conséquences négatives de la crise économique, l'attention doit se porter davantage sur la compétitivité et l'esprit d'entreprise. Il faudrait améliorer le fonctionnement de la filière de l'offre pour obtenir une répartition des coûts et des avantages plus équitable. Les organisations de producteurs devraient se développer et se renforcer. Des travaux sont nécessaires pour mettre en pratique le concept de croissance verte et pour étudier les synergies entre la demande de biens d'intérêt public et le renforcement nécessaire des revenus agricoles. Un système de soutien direct amélioré reste justifié, pour compenser les coûts supplémentaires et stabiliser les revenus. La PAC d'après 2013 devrait fournir un cadre européen solide, capable d'atteindre les défis partagés, avec des objectifs clairs et des financements suffisants. Au sein de ce cadre, la diversité est un fait et les régions devraient pouvoir déployer les politiques et les fonds de la PAC de manière plus flexible pour répondre aux besoins et problèmes locaux et pour permettre de réagir aux changements. Neue Herausforderungen lassen erkennen, dass die früheren Erfolge der GAP nicht als selbstverständlich angesehen werden können.Nach 2013 wird zum Wohle der Bürger und des Agrarsektors in Europa nach wie vor eine stabile europäische Agrarpolitik gebraucht. Die GAP wird sich jedoch weiterentwickeln müssen, um der Vision aus dem europäischen Agrarmodell entsprechen zu können. Das Augenmerk sollte hierbei nicht nur auf den Umgang mit den negativen Auswirkungen der Wirtschaftskrise, sondern ebenfalls auf Wettbewerbsfähigkeit und Unternehmertum gerichtet werden. Die Funktionsfähigkeit der Wertschöpfungskette sollte erhöht werden und zu einer gerechteren Verteilung von Kosten und Nutzen führen. Erzeugerorganisationen sollten ausgeweitet und gestärkt werden. Es muss viel getan werden, um das Konzept des Grünen Wachstums umzusetzen und die Synergien zwischen der Nachfrage nach öffentlichen Gütern und der Notwendigkeit für höhere Einkommen in der Landwirtschaft zu untersuchen. Ein verbessertes System für die Direktzahlungen ist nach wie vor gerechtfertigt, um zusätzliche Kosten auszugleichen und die Einkommen zu stabilisieren. Nach 2013 sollte die GAP einen stabilen EU-Rahmen bieten, um den gemeinsamen Herausforderungen mit klaren Zielen und ausreichender Finanzierung begegnen zu können. Innerhalb dieses Rahmens ist Platz für Diversität, und die Regionen sollten dazu in der Lage sein, die Politikmaßnahmen der GAP flexibler einzusetzen, um auf die Bedürfnisse vor Ort reagieren und sich den wechselnden Bedingungen anpassen zu können. [source] Agriculture Under the Public Eye: Who Cares for WhatEUROCHOICES, Issue 2 2004Cees Veerman Summary Agriculture Under the Public Eye: Who Cares for What? The new CAP is becoming geared towards a more sustainable agriculture that takes account of the needs of future generations. Achieving sustainability, however, means meeting three challenges-, (a) profit - strengthening the viability and competitiveness of the agricultural sector; (b) planet - the ecological challenge of promoting good environmental practices; and (c) people-the social challenge to improve the living conditions and economic opportunities in rural areas. In the food chain we see responses to consumer concerns about food safety, quality and welfare issues through the development and implementation of mandatory and voluntary quality control and assurance schemes. And the consolidation and internationalisation of the food retailing and the manufacturing industry is expected to continue. An important duality has emerged. On the one side, we find a state system of regulation, on the other a system of self-regulation, largely driven by the major forces in supply chain management, the food retailers in particular. A simple and effective regulatory environment for the agri-food complex is essential if we are to achieve our competitiveness goals. One of the priorities for discussion by politicians, therefore, should be whether current and expected policy and industry developments should lead to a review of the balance between markets and government, ,who cares for what?' l'agriculture aux yeux des politiques publiques qui doit faire quoi? La nouvelle PAC est maintenant bien orientée vers une agriculture plus durable, en mesure de tenir compte des besoins des générations futures. Une véritable durabilityé suppose cependant que soient relevés trois défis: a) le profit - renforcer la viabilityé et la compétitivité du secteur agricole; b) la planète - le défiécologique de promouvoir des pratiques favorables à l'environnement; c) les gens - le défi social d'améliorer les conditions de vie et les opportunités économiques dans les zones rurales. Du côté des filières alimentaires, la réponse à trouver aux inquiétudes des consommateurs vis à vis de la qualityé sanitaire et organoleptique des produits devrait pouvoir venir de l'élaboration de contrôles de qualityé et de systèmes d'assurances, à appliquer sur la base du volontariat ou à rendre obligatoires. En même temps, il faut s'attendre à la continuation du mouvement vers l'affermissement du rôle des industries alimentaires et du commerce de détail, ainsi qu'à leur internationalisation. Un système dual vient d'émerger: d'un côté, un système de réglementations étatiques, de l'autre, une autodiscipline, pilotée par les plus solides des maillons de la filière, en particulier les grandes surfaces. Un environnement réglementaire à la fois simple et efficace est essentiel pour atteindre l'objectif de compétitivité du complexe agroalimentaire, II en résulte que, pour les pouvoirs publics, une des grandes questions à discuter est de savoir dans quelle mesure l' évolution des conditions politiques et celle du développement industriel imposent une révision de l'équilibre actuel entre les marchés et les autorités gouvernementales; en d'autres termes, qui doit faire quoi ? Landwirtschaft in der öffentlichen Meinung; Wer ist wofür zuständig? Die neue GAP wird gerade auf eine nachhaltigere Landwirtschaft hin ausgerichtet, welche die Bedürfnisse der kommenden Generationen berücksichtigt. Nachhaltigkeit kann jedoch nur erzielt werden, wenn den folgenden drei Herausforderungen Rechnung getragen wird: (a) Ökonomie , Stärkung der Leistungs- und Wettbewerbsfähigkeit des Landwirtschaftssektors; (b) Ökologie , Förderung umweltgerechter Verfahrensweisen; und (c) Soziales - Verbesserung der Lebensbedingungen und der wirtschaftlichen Lage im ländlichen Raum. Im Bereich der Nahrungsmittelkette wird den Bedenken der Verbraucher hinsichtlich der Nahrun gsmittelsicherheit, der Qualität und der Wohlfahrt durch die Entwicklung und Implementierung von obligatorischen und freiwilligen Qualitätskontrollen und Sicherheitsprogrammen Rechnung getragen. Es ist davon auszugehen, dass sich die Konsolidierung und Lnternationalisierung im Bereich des Lebensmitteleinzel-handels und der weiterverarbeitenden Industrie fortsetzen wird. Es ist eine bedeutsame Dualität entstanden. Auf der einen Seite erfolgt eine Regulierung seitens des Staates, auf der anderen Seite erfolgt eine Selbstregulierung durch die Vermarktungskette, insbesondere durch den Lebensmitteleinzelhandel. Eine sowohl einfache als auch wirksame Regulierung der Agrar- und Ernährungswirtschaft ist von grundlegender Bedeutung für das Erreichen unserer Wettbewerbsziele. Daher sollte in der Politik mit Priorität diskutiert werden, ob die gegenwärtige und zukünftige Politik und auch die industrielle Entwicklung zu einem neuen Gleichgewicht zwischen Markt und Staatseingriffen führen sollte: Wer ist wofür zuständig? [source] Endemic species and ecosystem sensitivity to climate change in NamibiaGLOBAL CHANGE BIOLOGY, Issue 5 2006WILFRIED THUILLER Abstract We present a first assessment of the potential impacts of anthropogenic climate change on the endemic flora of Namibia, and on its vegetation structure and function, for a projected climate in ,2050 and ,2080. We used both niche-based models (NBM) to evaluate the sensitivity of 159 endemic species to climate change (of an original 1020 plant species modeled) and a dynamic global vegetation model (DGVM) to assess the impacts of climate change on vegetation structure and ecosystem functioning. Endemic species modeled by NBM are moderately sensitive to projected climate change. Fewer than 5% are predicted to experience complete range loss by 2080, although more than 47% of the species are expected to be vulnerable (range reduction >30%) by 2080 if they are assumed unable to migrate. Disaggregation of results by life-form showed distinct patterns. Endemic species of perennial herb, geophyte and tree life-formsare predicted to be negatively impacted in Namibia, whereas annual herb and succulent endemic species remain relatively stable by 2050 and 2080. Endemic annual herb species are even predicted to extend their range north-eastward into the tree and shrub savanna with migration, and tolerance of novel substrates. The current protected area network is predicted to meet its mandate by protecting most of the current endemicity in Namibia into the future. Vegetation simulated by DGVM is projected to experience a reduction in cover, net primary productivity and leaf area index throughout much of the country by 2050, with important implications for the faunal component of Namibia's ecosystems, and the agricultural sector. The plant functional type (PFT) composition of the major biomes may be substantially affected by climate change and rising atmospheric CO2, currently widespread deciduous broad leaved trees and C4 PFTs decline, with the C4 PFT particularly negatively affected by rising atmospheric CO2 impacts by ,2080 and deciduous broad leaved trees more likely directly impacted by drying and warming. The C3 PFT may increase in prominence in the northwestern quadrant of the country by ,2080 as CO2 concentrations increase. These results suggest that substantial changes in species diversity, vegetation structure and ecosystem functioning can be expected in Namibia with anticipated climate change, although endemic plant richness may persist in the topographically diverse central escarpment region. [source] Asymmetric Abstraction and Allocation: The Israeli-Palestinian Water Pumping RecordGROUND WATER, Issue 1 2009Mark Zeitoun The increased attention given to international transboundary aquifers may be nowhere more pressing than on the western bank of the Jordan River. Hydropolitical analysis of six decades of Israeli and Palestinian pumping records reveals how ground water abstraction rates are as asymmetrical as are water allocations. The particular hydrogeology of the region, notably the variability in depth to ground water, variations in ground water quality, and the vulnerability of the aquifer, also affect the outcome. The records confirm previously drawn conclusions of the influence of the agricultural lobby in maintaining a supply-side water management paradigm. Comparison of water consumption rates divulges that water consumed by all sectors of the farming-based Palestinian economy is less than half of Israeli domestic consumption. The overwhelming majority of "reserve" flows from wet years are sold at subsidized rates to the Israeli agricultural sector, while very minor amounts are sold at normal rates to the Palestinian side for drinking water. An apparent coevolution of water resource variability and politics serves to explain increased Israeli pumping prior to negotiations in the early 1990s. The abstraction record from the Western Aquifer Basin discloses that the effective limit set by the terms of the 1995 Oslo II Agreement is regularly violated by the Israeli side, thereby putting the aquifer at risk. The picture that emerges is one of a transboundary water regime that is much more exploitative than cooperative and that risks spoiling the resource as it poisons international relations. [source] An overview of the Turkish dairy sectorINTERNATIONAL JOURNAL OF DAIRY TECHNOLOGY, Issue 1 2008SERTAÇ GÖNENÇ The livestock sector and dairy subsector have great importance for Turkey, in terms of both nutrition and economy. The share of the livestock sector in the total agricultural production value has varied between 25% and 30% in the last three decades. Raw milk production is characterized by small-scale farms, with an average of three heads of dairy cattle per farm. Turkey's dairy industry was established and developed by the State with the opening of the Turkish Dairy Industry Institution (TSEK) in 1963 as a state-owned enterprise (SOE). TSEK facilitated modernization of the sector, created a dairy market and played a role in stabilizing the consumer and producer prices. In 1995, a liberalization movement in the agricultural sector started in Turkey and the TSEK enterprises were privatized. After privatization, producer prices decreased between 11.51% and 18.45% and consumer prices of dairy products increased in general. Today, the dairy processing sector has a dual structure that on one hand comprises many small- and medium-sized enterprises, while on the other features seven large holding companies that hold the largest market share (CR4 71). This study aims to show that the restructuring of the agricultural SOEs in the first place resulted in undesirable impacts, and thus that the planning and implementation of the privatization of the state enterprises in the dairy sector should be taken as a strategy in the medium term, using the experiences of other developing countries. [source] Assessment of the energy and exergy utilization efficiencies in the Turkish agricultural sectorINTERNATIONAL JOURNAL OF ENERGY RESEARCH, Issue 9 2006Zafer Utlu Abstract This study deals with evaluating the energy and exergy utilization efficiencies in the Turkish agricultural sector over a 12-year period from 1990 to 2001. In the energy and exergy analyses, two main energy sources, namely fuels and electricity, are taken into consideration, while the sectoral energy and exergy efficiencies are compared for this period. These main energy sources include diesel for tractors and other vehicles, and electricity for pumps. Overall energy utilization efficiencies are obtained to vary between 29.1 and 41.1%, while overall exergy utilization efficiencies are found to range from 27.9 to 37.4% in the analysed years, respectively. It may be concluded that the present technique proposed here may be used as a useful tool in analysing and evaluating the energy and exergy utilization efficiencies, identifying energy efficiency and/or energy conservation opportunities and dictating the energy strategies of countries.

[source] The suitability of computer-based training for workers with limited formal education: a case study from the US agricultural sectorINTERNATIONAL JOURNAL OF TRAINING AND DEVELOPMENT, Issue 4 2006W. Kent Anger The suitability of computer-based instruction (CBI) for workers with limited education was evaluated in an Hispanic orchard workforce that reported little computer experience and 5.6 mean years of formal education. Ladder safety training was completed by employees who rated the training highly (effect size [d_gain] = 5.68), and their knowledge of ladder safety improved (d_gain = 1.45). There was a significant increase (p < 0.01) in safe work practices immediately after training (d_gain = 0.70), at 40 days post training (d_gain = 0.87) and at 60 days (d_gain = 1.40), indicating durability. As in mainstream populations, reaction or affective ratings correlated well with utility ratings, but not with behavior change. This demonstrates that an agricultural workforce with limited formal education can learn job safety from CBI and translate the knowledge to work practice changes, and those changes are durable. [source] Irrigation and drainage systems research and development in the 21st century,IRRIGATION AND DRAINAGE, Issue 4 2002Bart Schultz irrigation; drainage; développement durable; système de réseau Abstract One critical problem confronting mankind today is how to manage the intensifying competition for water between expanding urban centres, traditional agricultural activities and in-stream water uses dictated by environmental concerns. In the agricultural sector, the dwindling number of economically attractive sites for large-scale irrigation and drainage projects limits the prospects of increasing the gross cultivated area. Therefore, the required increase in agricultural production will necessarily rely largely on a more accurate estimation of crop water requirements on the one hand, and on major improvements in the construction, operation, management and performance of existing irrigation and drainage systems, on the other. The failings of present systems and the inability to sustainably exploit surface and groundwater resources can be attributed essentially to poor planning, design, system management and development. This is partly due to the inability of engineers, planners and managers to adequately quantify the effects of irrigation and drainage projects on water resources and to use these effects as guidelines for improving technology, design and management. To take full advantage of investments in agriculture, a major effort is required to modernize irrigation and drainage systems and to further develop appropriate management strategies compatible with the financial and socio-economic trends, and the environment. This calls for a holistic approach to irrigation and drainage management and monitoring so as to increase food production, conserve water, prevent soil salinization and waterlogging, and to protect the environment. All this requires, among others, enhanced research and a variety of tools such as water control and regulation equipment, remote sensing, geographic information systems, decision support systems and models, as well as field survey and evaluation techniques. To tackle this challenge, we need to focus on the following issues: affordability with respect to the application of new technologies; procedures for integrated planning and management of irrigation and drainage systems; analysis to identify causes and effects constraining irrigation and drainage system performance; evapotranspiration and related calculation methods; estimation of crop water requirements; technologies for the design, construction and modernization of irrigation and drainage systems; strategies to improve irrigation and drainage system efficiency; environmental impacts of irrigation and drainage and measures for creating and maintaining sustainability; institutional strengthening, proper financial assessment, capacity building, training and education.

Résumé Aujourd'hui le problème critique pour l'humanité est comment manier la compétition intensifiante pour de l'eau entre les centres urbains en expansion, pour des activités traditionnellement agricoles et pour l'usage de l'eau fluviale prescrit par des conditions écologistes. Dans le secteur agricole les perspectives d'agrandir les champs cultivés bruts sont limitées par le nombre diminuant des terrains économiquement attractifs pour des projets d'irrigation et du drainage de grande envergure. Par conséquent l'augmentation nécessaire de la production agricole comptera surtout sur une évaluation plus précise du besoin des plantes d'un côté, et de l'autre sur de grandes améliorations dans la construction, dans l'opération, dans le management et dans la performance des systèmes d'irrigation et du drainage. On peut attribuer les défauts des systèmes actuels et l'incompétence d'exploiter durablement les ressources hydriques de surface et souterraines au planification, au système de la gestion de l'eau et au système du développement. Cela est partiellement dû à l'incapacité des ingénieurs, des planificateurs et des gérants, de quantifier adéquatement les effets des projets d'irrigation et de drainage sur les ressources hydriques et d'utiliser ces résultats pour améliorer la technologie, la planification et la gestion de l'eau. Pour profiter le mieux possible des investissements dans l'agriculture, on exige un effort considérable pour moderniser les systèmes d'irrigation et de drainage et pour développer des stratégies de gestion de l'eau qui doivent être appropriées et compatibles avec les tendances financières et socio-économiques et avec l'environnement. Ceci a besoin d'une procédure holistique pour la gestion et le monitorage de l'eau, pour augmenter la production d'aliments, pour conserver l'eau, pour prévenir la salination du sol et pour protéger l'environnement. Tout cela demande, entre autres choses, une recherche d'avant-garde et une variété d'instruments comme les contrôles du régime hydrique et les appareils de régulation, la télédétection, les systèmes de l'information géographique, les systèmes et les modèles de support de décision et de même les levés sur le terrain et les techniques d'évaluation. Pour entreprendre ce défi nous devons nous concentrer sur les questions suivantes: capacité de mettre enoeuvre des technologies nouvelles; le développement des procédures pour intégrer la planification et la gestion des systèmes d'irrigation et de drainage; l'analyse pour identifier les causes et les effets de forcer à la performance des systèmes d'irrigation et de drainage; l'évapotranspiration et les méthodes de calcul en question; l'évaluation des exigences hydriques des cultures; les technologies pour le dessein, la construction et la modernisation des projets d'irrigation et de drainage; les stratégies pour améliorer l'efficacité des systèmes d'irrigation et de drainage; les impacts des projets d'irrigation et de drainage et des mesures appropriées pour créer et entretenir la durabilité; l'amélioration du contexte institutionnel, l'évaluation financière, la formation et l'amélioration des compétences techniques.

[source] The Chilean Agrarian Transformation: Agrarian Reform and Capitalist ,Partial' Counter-Agrarian Reform, 1964,1980JOURNAL OF AGRARIAN CHANGE, Issue 1 2007Free-Market Neoliberalism, Part 1: Reformism, Socialism This article, which is published in two parts, is an empirical analysis of the Chilean agrarian reform (1964,1973) and ,partial' counter-agrarian reform (1974,1980). Its aim is to explain and interpret their logic and the changes they brought to Chile's agrarian property regime in particular and Chilean life in general. Chile's agrarian reform was successful in expropriating (under the Frei and Allende administrations, 1964,1973) the great estates of the hacienda landed property system. The capitalist ,partial' counter-reform then redistributed them (under the military, 1974,1980). CORA, the country's agency for agrarian reform, expropriated and subsequently redistributed 5809 estates of almost 10 million hectares, or 59 per cent of Chile's agricultural farmland. A large amount of the expropriated land (41 per cent) benefited 54,000 peasant households with small-sized family farms and house-sites. The rest of the farmland benefited efficient and competitive commercial farmers and agro-business and consolidated medium-sized farms. Of central concern is the role of the agrarian reform and subsequent ,partial' counter-reform processes in fostering the transformation of the erstwhile agrarian structure of the hacienda system toward agrarian capitalism. The redistribution of the agricultural land previously expropriated made possible the formation of an agro-industrial bourgeoisie, small commercial farmers, an open land market and a dynamic agricultural sector. While, however, under military rule, a selected few benefited with family farms and became independent agricultural producers, a large majority of reformed and non-reformed campesinos were torn from the land to become non-propertied proletarians in a rapidly modernizing but highly exclusionary agricultural sector. [source] Is Oligopoly a Condition of Successful Privatization?JOURNAL OF AGRARIAN CHANGE, Issue 2 2002The Case of Cotton in Zimbabwe Zimbabwe embarked on market liberalization in the early 1990s, leading towards increasing participation of private capital in the agricultural sector. This paper examines the emergent shape of the private marketing chain for cotton in Zimbabwe, based on fieldwork conducted in the 1999-2001 cotton marketing seasons. The privatization of the cotton marketing board replaced state monopoly with private oligopoly and competition is still seriously underdeveloped, especially on price. However, because of a concentrated market and collective private action, important aspects of earlier systems of coordination have been maintained, preventing downgrading of Zimbabwean cotton lint after liberalization. The paper concludes with a discussion about (absence of) competition and commodity system sustainability in liberalized markets. [source] Tariff Peaks for Agricultural and Food Products: their Incidence and Alternatives for their RemovalJOURNAL OF AGRICULTURAL ECONOMICS, Issue 1 2002Javier Fernández The aim of the paper is the analysis of the current market access situation in global agricultural markets for the post-Uruguay Round period. It identifies those commodity groups in the food and agricultural sector for which tariff peaks exist, and examines how various tariff-cutting formulae would affect their levels. The related issues of tariff complexity and of the administration of Tariff Rate Quotas are also reviewed here. Results show that the implementation of the Uruguay Round agreement has not significantly reduced agricultural protection, since high tariff peaks and nontransparent tariff structures still persist. A repetition of the Uruguay Round cuts would not solve the problem of high protection levels either, and only the introduction of more aggressive harmonising formulae could lead to a true liberalisation of world agricultural and food markets. [source] Structural change in the West German agricultural sectorAGRICULTURAL ECONOMICS, Issue 2009Silke Huettel Structural change; Strategic competition; Land market; Markov chain Abstract This article explains regionally differentiated patterns of structural change based on a theoretical framework dealing with strategic interaction of farms on the land market. The main research question focuses on the causes of regionally persistent structures. An empirical Markov chain model is defined for the West German agricultural sector. The model is used to explain the probabilities of farm growth, decline, or exit in terms of the current and former regional farm size structure. Further, the impact of variables describing the regional farm structure, thereby indicating market power of the large, the potential of high competition for land within a region, and possibly high rents of the status quo in combination with sunk costs, is quantified. The results confirm the relevance of strategic interaction as a crucial determinant of persistent regional differences in the farm size structure over time. [source] The impact of the 1999 CAP reforms on the efficiency of the COP sector in SpainAGRICULTURAL ECONOMICS, Issue 3 2009Fatima Lambarraa Agenda 2000; Distance function; Efficiency; Spanish COP sector Abstract The cereal, oilseeds, and protein crop sector (COP) occupies a prominent position within the European Union's agricultural sector. Within Spain, the COP sector accounts for almost a third of total Agricultural Guidance and Guarantee Fund expenses, and half of the utilized agricultural area (UAA). The COP sector is not only relevant because of its physical and economic magnitude, but also because of the political attention it receives. The Common Agricultural Policy (CAP) reforms that occurred during the 1990s paid special attention to this sector. This article aims to determine the impacts of Agenda 2000 on a sample of Spanish COP farmers' production decisions by using an output-oriented stochastic distance function. The distance function allows for an assessment of the reform-motivated changes on total output, input used, input composition, and crop mix. It also permits an assessment of the impacts of the reform on farms' technical efficiency. Results show that the reform has shifted the production frontier inward and changed output composition in favor of voluntary set-aside land. With respect to input composition, Agenda 2000 induced a decrease in land, fertilizers, pesticides, and other inputs in favor of labor. In addition, Agenda 2000 has had a negative impact on technical efficiency. [source] Poverty decline, agricultural wages, and nonfarm employment in rural India: 1983,2004AGRICULTURAL ECONOMICS, Issue 2 2009Peter Lanjouw Poverty; Agricultural labor; India; Nonfarm employment Abstract We analyze five rounds of National Sample Survey data covering 1983, 1987/1988, 1993/1994, 1999/2000, and 2004/2005 to explore the relationship between rural diversification and poverty. Poverty in rural India has declined at a modest rate during this time period. We provide region-level estimates that illustrate considerable geographic heterogeneity in this progress. Poverty estimates correlate well with region-level NSS data on changes in agricultural wage rates. Agricultural labor remains the preserve of the uneducated and also to a large extent of the scheduled castes and scheduled tribes. We show that while agricultural labor grew as a share of total economic activity over the first four rounds, it had fallen back to the levels observed at the beginning of our survey period by 2004. This all-India trajectory also masks widely varying trends across states. During this period, the rural nonfarm sector has grown modestly, mainly between the last two survey rounds. Regular nonfarm employment remains largely associated with education levels and social status that are rare among the poor. However, casual labor and self-employment in the nonfarm sector reveals greater involvement by disadvantaged groups in 2004 than in the preceding rounds. The implication of this for poverty is not immediately clear,the poor may be pushed into low-return casual nonfarm activities due to lack of opportunities in the agricultural sector rather than being pulled by high returns offered by the nonfarm sector. Econometric estimates reveal that expansion of the nonfarm sector is associated with falling poverty via two routes: a direct impact on poverty that is likely due to a pro-poor marginal incidence of nonfarm employment expansion; and an indirect impact attributable to the positive effect of nonfarm employment growth on agricultural wages. The analysis also confirms the important contribution to rural poverty reduction from agricultural productivity, availability of land, and consumption levels in proximate urban areas. [source] An analysis of industrial,agricultural interactions: a case study in PakistanAGRICULTURAL ECONOMICS, Issue 1 2000Shida Rastegari Henneberry Abstract This paper empirically analyzes the relationship between Pakistan's industrial and agricultural sectors. Pakistan was chosen because of its status of a semi-industrialized country with heavy dependence on the agricultural sector. The relationship between cotton production and industrial growth is also evaluated due to the prominence of this crop in Pakistani agriculture. The results indicate that these sectors are complementary, yet industry tends to benefit more from agricultural growth than vice versa. The timing of this information is critical, as Pakistan's policy makers now face major agricultural policy reforms in their quest for continued industrial development. [source] WATER SUPPLY EVALUATION OF TAIWAN'S SILICON VALLEY,JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 5 2001Wen-Cheng Huang ABSTRACT: The objective of this paper is to examine a deficit in water for the Hsinchu area, the location of Taiwan's "Silicon Valley." The methods suggested in this paper to diagnose water shortage problems are simple and practical. The results show that Hsinchu is in an area without sufficient water to meet demand for domestic and industrial uses. Until the completion of the Baoshan II Reservoir in 2006, the most feasible options for the Taiwan Water Supply Corporation to offset the water deficiency in Hsinchu City over the next five years are: (a) to obtain water gratuitously from the southern Yungheshan Reservoir; (b) to import additional water at an extra charge from other sources such as the northern Shihmen Reservoir and the agricultural sector; and (c) to conduct a comprehensive water conservation program at the Hsinchu Science-based Industrial Park. [source] Agricultural policies and the emergence of cotton as the dominant crop in northern Côte d'Ivoire: Historical overview and current outlookNATURAL RESOURCES FORUM, Issue 2 2009Oluyede Clifford Ajayi Abstract In most of sub-Saharan Africa, where the agricultural sector experiences dismal performance and is characterized by a gloomy picture, the cotton sub-sector in Côte d'Ivoire is often mentioned as a "success story" given the spectacular rise in the quantity of cotton production and the profile of the crop within the farming system. What are the historical and political antecedents of the development of cotton and the factors responsible for the feat accomplished in the midst of general failures in the same continent? To what extent can cotton be regarded as a "success story" and, what lessons can be drawn for agricultural development strategies based on the Ivorian case study? This paper traces the historical and socio-political background of cotton development in Côte d'Ivoire and identifies key policy and institutional interventions that have influenced the rise of cotton production and its emergence as the dominant crop in the farming systems of the country. Four stages in Ivorian cotton development are identified: planning, take off, crisis and the renaissance phases. The study demonstrates how a combination of good planning, technological advancement and appropriate policy and institutional conditions have contributed significantly to the rise of cotton production and its influence on the agricultural economy of northern Côte d'Ivoire. The study also highlights how the sustainability of agricultural development has been impacted by domestic and international policies and political events over which smallholder farm families have little control, and can at best only respond to. Important questions about cotton development in Côte d'Ivoire are raised that need to be answered before the program can be categorized conclusively as a success story. The study shows that there are no quick fixes to agricultural development in the sub-region. Rather, good planning and putting the necessary building blocks in place are important prerequisites. It is recommended that agricultural development efforts in the continent take cognizance of the complexity of the sector and address the inter-relationships that exist among the technical, policy, market and institutional factors that combine individually and collectively to influence African agriculture. [source] Understanding the ergonomic risk for musculoskeletal disorders in the United States agricultural sectorAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 7 2007Kermit G. Davis PhD Abstract Introduction Farming is a very large industry in the United States. Understanding the risks for injuries and more specifically musculoskeletal disorders in this industry poses a challenge for health officials. Methods A review was conducted of the existing peer-reviewed publications prior to December 2006 about injuries and musculoskeletal disorders for farmers and farm workers. The aim was to review existing knowledge concerning: (1) the prevalence, types, and causes of farm-related injuries, paying particular attention to musculoskeletal disorders and the special populations within the agricultural sector, and (2) interventions that have been developed to reduce risk factors associated with farm-related injuries. Results Farmers and farm workers experience high rates of low back, shoulder, and upper extremity disorders. Musculoskeletal disorders may disproportionately affect farm youth and migrant workers due to the types of farm tasks performed. There is an urgent need for improved and validated interventions to reduce exposures and to improve the health of farmers and farm workers. Discussion Future farm-related musculoskeletal disorder research should emphasize: (1) better identification of exposures for special populations, (2) development of interventions for diverse farm populations, and (3) identification of additional exposures for musculoskeletal disorders. Inadequate understanding of musculoskeletal disorders in farming impedes efforts to prevent this common and important type of occupational injuries on farms. Am. J. Ind.

[source] Survival and expansion: migrants in Greek rural regionsPOPULATION, SPACE AND PLACE (PREVIOUSLY:-INT JOURNAL OF POPULATION GEOGRAPHY), Issue 6 2008Charalambos Kasimis Abstract Migratory movements towards southern Europe have increased considerably in the past 20 years. An important aspect of this process is connected to the agricultural sector and rural regions , a development connected to agriculture's particular weight in the economies and societies of all southern European countries. However, their role is not restricted to agriculture. They are also related to non-agricultural economic activities and the overall support of aged populations, especially in marginal or mountainous rural areas. This paper draws on the qualitative and quantitative findings of two research projects carried out in three exemplar rural regions of Greece and over two different periods: 2000,2002 and 2004,2006. The aim of the research was the empirical investigation of the economic and social implications of the settlement and employment of migrant labour in rural Greece. The paper moves from the presentation of the theoretical and methodological framework to the presentation of the main findings for each period of the research. The socioeconomic implications of migrant employment and settlement in the regions studied are revealed in the light of the recent Common Agricultural Policy changes, and the changes following the implementation of ,regularisation programmes'. Additionally, the characteristics of migration trends in these regions are identified and the formation of new migrant social groups, with different prospects of social integration and mobility, is revealed.

[source] The sequencing of reform policies in China's agricultural transition,THE ECONOMICS OF TRANSITION, Issue 3 2004Alan De Brauw Abstract This paper provides evidence regarding gains due to agricultural market liberalization in China. We empirically identify the different effects that incentive and farm restructuring reforms and gradual market liberalization have on China's agricultural economy during its transition period. We find that average gains within the agricultural sector due to reforms that improved incentives and increased decision-making authority of producers exceed gains due to market liberalization by a large margin. Our method of analyzing the effects of transition policies on economic performance can be generalized to other reform paths in other transition economies. [source] COLONIALISM AND LONG-RUN GROWTH IN AUSTRALIA: AN EXAMINATION OF INSTITUTIONAL CHANGE IN VICTORIA'S WATER SECTOR DURING THE NINETEENTH CENTURYAUSTRALIAN ECONOMIC HISTORY REVIEW, Issue 3 2008Edwyna Harris colonialism; democracy; economic growth; institutional efficiency; water rights Institutional change in water rights in the nineteenth century Australian colony of Victoria raised institutional efficiency, which contributed to long-run economic growth. High-quality human capital and the extension of voting rights (franchise) were crucial for efficient institutional change in the water sector. Quality human capital (literacy) appeared to increase the rural population's awareness of the economic impact of the existing structure of water rights that may have constrained growth in the agricultural sector and reduced investment incentives. Extension of the franchise allowed the rural population to exert political pressure for enactment of change in water rights, which resulted in efficiency-enhancing policies and efficient institutions. The findings show these two factors were more important than Victoria's British colonial heritage in determining whether growth-enhancing institutional change took place. [source] Exploring the impact of R&D and climate change on agricultural productivity growth: the case of Western Australia,AUSTRALIAN JOURNAL OF AGRICULTURAL & RESOURCE ECONOMICS, Issue 4 2010Ruhul A. Salim This article empirically examines the impact of R&D and climate change on the Western Australian Agricultural sector using standard time series econometrics. Based on historical data for the period of 1977,2005, the empirical results show that both R&D and climate change matter for long-run productivity growth. The long-run elasticity of total factor productivity (TFP) with respect to R&D expenditure is 0.497, while that of climate change is 0.506. There is a unidirectional causality running from R&D expenditure to TFP growth in both the short run and long run. Further, the variance decomposition and impulse response function confirm that a significant portion of output and productivity growth beyond the sample period is explained by R&D expenditure. These results justify the increase in R&D investment in the deteriorating climatic condition in the agricultural sector to improve the long-run prospects of productivity growth. [source] Dynamic general equilibrium analysis of improved weed management in Australia's winter cropping systems,AUSTRALIAN JOURNAL OF AGRICULTURAL & RESOURCE ECONOMICS, Issue 4 2005Glyn Wittwer A recent analysis indicated that the direct financial cost of weeds to Australia's winter grain sector was approximately $A1.2bn in 1998,1999. Costs of this magnitude represent a large recurring productivity loss in an agricultural sector that is sufficient to impact significantly on regional economies. Using a multi-regional dynamic computable general equilibrium model, we simulate the general equilibrium effects of a hypothetical successful campaign to reduce the economic costs of weeds. We assume that an additional $50m of R&D spread over five years is targeted at reducing the additional costs and reduced yields arising from weeds in various broadacre crops. Following this R&D effort, one-tenth of the losses arising from weeds is temporarily eliminated, with a diminishing benefit in succeeding years. At the national level, there is a welfare increase of $700m in discounted net present value terms. The regions with relatively high concentrations of winter crops experience small temporary macroeconomic gains. [source] Potentiel de Productivité et Efficacité Technique du Secteur Agricole en AfriqueCANADIAN JOURNAL OF AGRICULTURAL ECONOMICS, Issue 3 2006Joachim Binam Nyemeck This study utilizes frontier metaproduction functions to analyze inter-region agricultural productivity differences. Technical efficiency scores are examined through estimation of stochastic frontiers for 16 African countries divided into three different regions (West Africa, East and Southern Africa, and North Africa) from 1970 to 2001. The idea is to explore the differences in efficiency and technological gaps of agricultural sector. Apart of common traits that characterize African agricultural sector, countries exhibit national and regional specificities. These diversities are such that it is difficult to make valuable generalizations. It appears from the results that: in West Africa, the level of technology is relatively good, meaning that there is no problem of input constraints. By contrast, the efficiency with which inputs are used is very low. The situation is very different in the East and Southern Africa, with the level of technology relatively low and appreciable technical level. At least, the North Africa countries make a performing mixture between technology and efficiency. Cette étude utilise les Meta frontières de production pour analyser les différences inter-régionales de la productivité agricole. Les niveaux d'efficacité technique sont examinées par l'estimation des frontières stochastiques de 16 pays africains regroupés en trois régions (l'Afrique de l'Ouest, l'Afrique de l'Est et Australe, et l'Afrique du Nord), sur une période allant de 1970 à 2001. L'idée étant d'explorer les différences d'efficacité et les écarts technologiques du secteur agricole. Au-delà des simples traits communs qui caractérisent le secteur agricole africain, on trouve des expériences nationales et régionales dont il est difficile, du fait de leur grande diversité, de tirer des généralisations valables. Des résultats de l'étude, il ressort que: en Afrique de l'Ouest, le niveau technologique est relativement satisfaisant, traduisant le fait que la présence des inputs ne représente pas une contrainte. Par contre le niveau d'efficacité avec lequel ces intrants sont utilisés est assez faible. La situation est tout autre en Afrique de l'Est et Australe avec un niveau technologique relativement faible et un niveau d'efficacité appréciable. L'Afrique du nord enfin fait un savant dosage entre efficacité et technologie. [source] | |||||||||||||||||||||||||||||||
