This paper examines changes in agricultural productivity in 10 Sub-saharan countries. The relative performance of agricultural sector was gauged using data envelopment analysis. From a panel data set of the 10 countries which included the 28-year period 1972-1999, mathematical programming methods were used to measure Malmquist indexes of total factor productivity. It was found that, during that period, total factor productivity have experienced a negative evolution in sample countries. A decomposition of those measures suggest that, most of the weak performance of factors productivity is attributable more to technological change than technical efficiency change. French-speaking countries better succeeded to raise their productivity than English-speaking countries do. In addition, it have been found that Sahelian countries failed to rise their agricultural productivity compared to forest countries where a positive evolution have been detected.

This paper seeks to address the question: why does poverty persist in rural Ethiopia? We argue that it is largely a lack of entitlements to fundamental livelihood assets which urges poor rural farmers into livelihood diversification to make a living. We base our findings on empirical work, which is based on information gathered from a three-round survey of 149 rural households in Ethiopia during 1999/2000 cropping season. The FGT poverty index is employed to examine the extent and severity of rural poverty and reveals that nearly 40% of the sample households live below poverty line with average poverty gap of 0.047. The binary logit estimates shed light on factors behind the persistence of poverty and indicates that rural poverty is strongly linked to entitlement failures to crucial assets such as land, human capital and oxen. The study also reveals that poor households attempt to smooth their consumption and income through livelihood diversification, among which petty trading, charcoal making and fuelwood gathering for sale, brewing and

A new procedure is developed to estimate innovation possibility frontiers and test for biases in technological change. Using data on four inputs (land, machinery, chemicals and labour) from central Canada (Ontario and Quebec) over the period 1926-1985, we find that the innovations possibilities frontier shifts neutrally over time. This is consistent with Ahmad.s model of induced innovations, but is not consistent with de Janvry.s application of Ahmad.s model to the historical development of Argentine agriculture. Agricultural research in Canada has been conducted with the objective of developing cost minimizing technologies. Empirical support was found for this notion in the development of the innovation possibilities frontier.

This article considers the impacts of (de)coupled farm sector support on the locations of farming and agro-industrial activity. An economic geography model is developed which has two types of regions, one with extensive agricultural production (rural), the other with intensive farming that is more densely populated (urban). The farm and agro-industrial sectors are vertically linked. A service sector that is not directly linked to either basic industry is also explicit. We show that coupled and decoupled subsidies affect the spatial distribution of farming, industry, and service sector activity. Support that is provided to all farmers regardless of crop, thus semi-decoupled, increases spatial agglomeration. Support targeted to farmers of particular crops, especially rural comparative advantage crops, favors increased farming in rural areas but spatial agglomeration of non-farm activity still occurs. This latter targeting approach is used in the European Union.

This paper presents a comparative method (SICOM) to evaluate complex site conditions at the level of a Federal State (Brandenburg) and at different areal units. The methodology uses primary site conditions and provides the possibility to objectively compare and judge different ecological questions. Objects with heterogeneous content are pooled in comparison groups. Consideration of the main site characteristics allows a goal-oriented allocation of subsidies. The use of SICOM is demonstrated for the wind and water erosion risk assessment across different scales from Federal State down to a parcel of land. The “parcel” aggregation-level proves to be useful to assess the erosion risk. Larger scales are less useful in the assessment of subsidies policy with regard to erosion risk. SICOM is demonstrated to be suitable for comparing and assessing regional aspects more objectively.

Commercial producers, brokers, exporters and spinners dominate the wool supply chain in South Africa. Until recently smallholder farmers in the Transkei region had limited access to a profitable market outlet for their wool. In response, the South African wool industry has taken the initiative to help local farmers by building shearing sheds, under which the local association can bulk the wool and trade directly with the brokers. More direct access to the wool brokers is a prerequisite for the farmer to develop a viable business.

This article investigates on the effect of membership in the local shearing shed association on the farmers. revenue. A two-step regression model of the gross margin is used to analyse whether farmers selling through the local association have better financial records as compared to those who sell their wool to local traders. This article exemplifies how institutional innovation through local marketing associations can contribute to economic development in poor rural areas.

This paper's aim is an assessment of economic effects of Slovenia’s accession to the EU in the field of agriculture and a discussion about some key dilemmas about the introduction of CAP in the new member states. For the purpose of assessing economic effects, a new sectoral model of Slovenian agriculture APAS-PAM has been compiled which allows assessment of market and income effects for ten key agricultural products with regard to various accession scenarios. The accession under the scenario of equal treatment of new member states would bring significant improvements in the aggregate income levels. On the other hand, discrimination of the candidate countries in the field of direct payments (“phasing in” process) would result in a fall of aggregate income level by an eighth. Moreover, noncompetitive production structures in the food-processing sector would deteriorate the economic situation of agricultural production by up to further 40 %. The positive effects of different accession scenarios are expected in the sugar beet and - under assumption of eligibility for direct payments - also in coarse grains, beef and sheep meat production. The economic situation in milk production is not expected to change significantly. The negative accession effects can be expected in pigmeat, cereal, egg and, potentially, poultry production. The results reveal a great significance of the equal treatment and differentiation approach to negotiation process for the preservation of the economic situation of Slovenian agriculture after accession. This holds especially for cereal, beef and sheep meat production.

The new Rural Development Regulation of the EU reflects the shift of attention within rural areas from agricultural production towards rural development and embraces both, farmers and non-farm residents. While agricultural production is required to comply with environmental standards, rural areas also have to fulfil the growing demand for landscape, outdoor recreation and wildlife conservation. This paper develops a model of a rural area where farmers and non-farm residents live together. A central government uses a combination of two-policy instruments - direct compensation payments and public services - aimed at encouraging farmers to adopt environmentally beneficial practices and at the same time to increase the provision of country-side amenities and the sustained vitality of the rural area. The optimal mix of the policy instruments is evaluated under various governmental objectives. The analysis suggests that a combination of direct payments to farmers with the supply of local public services is a promising tool for rural policy development initiatives in the EU.

The present study attempts to offer more insights into the Greek wine market with emphasis on wines produced from organically grown grapes by relating wine choice to consumers’ personal value structure. With the use of a qualitative sample and applying the Means-end Chains methodology and the corresponding “laddering” interviewing technique, it attempts first to reveal the way basic motives are linked to wine shopping behaviour of consumers and the way wine purchase-relevant knowledge is stored and organised in their memory in relation to their personal values. Then, by discriminating between organic food buyers and non-buyers, the study identifies motivational and cognitive discriminating differences between the two consumer types, which can offer a solid explanation as to their distinctive purchasing behaviour in respect of the organic products.

The paper proposes the use of meta models to determine the optimal intertemporal management of soil and phosphorus losses from agricultural land. This approach allows finding a equilibrium of the economic and biophysical system simultaneously. In contrast to the existing literature the model takes account of nonlinear relationships and of a large number of agricultural activities. The mathematical problems arising from this complex setup are addressed and the model is solved numerically. The results show that the second best policy in form of soil protection scores is highly inefficient, while another second best policy in form of land-use taxes is nearly as efficient as the first best policy.

In this paper, we attempt to shed some light on the state of current thinking in Europe about rural development and policy. To do so, the priorities and preferences of European agricultural economists who work in the area of rural development policy were identified using a survey that asked the following questions: who do we believe needs help, what are the problems and objectives, which policies are likely to be effective, who is able to deliver, and where do we get these ideas? The paper documents the diversity in rural development problems and favored tactics across Europe.

This book offers a coherent perspective on the transition to a market-based agri-food system in the Central and Eastern European Countries and the New Independent States of the former Soviet Union. It provides a formal analysis of the entire food chain from farm inputs to final consumers, including imports and exports, and covers all major components of the system, from food security, multinationals, and commercial law, to theoretical approaches to prices, transaction costs, and bilateral monopolies.

В книге представлен анализ перехода к основанной на рыночных условиях хозяйствования агропродовольственной системе в странах центральной и восточной Европы, СНГ. Авторами рассматривается вся продовольственная цепочка от фермера до потребителя, структура, задействованные экономические агенты, импорт и экспорт, проблемы продовольственной безопасности, роль транснациональных корпораций, процессы ценообразования, трансакционные издержки, институты.

This paper assesses and quantifies the consequences of world trade liberalization in agriculture on trade and food security of Sudan. Sudan, with the agricultural sector as the main sector of economy, is characterized by its small open economy, and is classified as one of the least developed countries. Thus, Sudan becomes more vulnerable to any changes in international agricultural markets. The liberalization of international agricultural trade has a great influence on Sudan's food security and on the whole economy. An extended form of a multi-market model for Sudan is developed and used for the analysis. The model embodies important characteristics of agriculture in Sudan like substitution effects and stages of production.

As agriculture is the main sector of Sudan's economy, the model is extended to explicitly integrate some of the key important macroeconomic linkages, and to establish certain feedback effects between agriculture and the macro-economy. The model simulations reveal that a higher world market price would overall lead to measurable gains in food security and agricultural trade of the country. However, when the effect of a higher cost of production is considered, the positive results are reversed. Furthermore, the results of the model simulations show that the domestic policy environment matters very much with respect to the potential impact of world trade liberalization of agriculture. The paper concludes that Sudan should reorient its national policies towards export promotion in order to benefit from the new emerging trading opportunities in world markets. However, to capture a greater benefit from the new environment in the international markets, Sudan should consider and manage carefully all factors, domestically or internationally - e.g. quality standard, loss of preference, dumping effects - that hinder its economic and trade growth.

The paper reports on the experiences gained from conducting the mid-term evaluation of SAPARD Program in Slovenia. The methodological approach lies in comparative analysis of two approaches: empirical approach, based on the application of Input-Output model and conventional approach based on application of evaluation techniques as proposed by the Guidelines prescribed by the European Commission. Limited scale of implementation has raised problems in economy-wide assessment of the impact and success of the Program. In some cases, quantitative relationships were also hard to assess due to the impact of external influences. Important limitations were found also in the case of conventional evaluation approach. The analysed case encountered some data-related problems (deficient monitoring data, almost exclusive dependence on primary data). There is also a more systemic problem of a limited contextual scope of this evaluation approach, which fails to provide sufficient information in the policy formation phase. Apart from comparison of alternative evaluation approaches, the paper also attempts to provide some wider implications for adoption of 'evaluation paradigm' in rural development policy in countries without a previous experience in this field.

In comparison to large-scale natural landscapes separated from extensively used agricultural production landscapes in North America or Australia, German and Central Europe landscapes are all characterised by predominantly agricultural landscapes with few “rests of nature”. Due to the high population density, different types of land users demand different functions of the landscape. In addition to food production, there is a high demand for protection of cultural heritage by caring for e.g. hedgerows in the landscape. The aim of this study was to estimate the costs arising from the maintenance of landscape elements in landscapes situated on land with different site conditions. As an example, the distribution of hedgerows on sites of varying agricultural quality were considered. The calculations were undertaken on the entire area of Baden- Wuerttemberg in Southwest Germany, comprising various administrative districts. The association between ecological and economic information was analysed statistically and with the help of GIS. The results indicate that the costs for landscape element protection differ within the state of Baden-Wuerttemberg and that there is a lot of economic pressure against hedgerow biotopes existing in certain districts. Measures for protection such as agri-environmental programmes should consider the different landscape-dependent costs.
