The menu approach of the second pillar of the CAP allows regions/countries to select those rural development measures which suit their needs best. The selection from the second pillar menu, which consists of 22 rural development measures, has to be reported in the Rural Development Plan. In this article we test the hypothesis ‘Regions select a few measures from the menu which are according to their rural development needs.’ For this purpose, we analysed three main steps which have to be taken in the application of the menu approach: (1) the identification of rural development priorities; (2) the selection of rural development measures to relieve these rural development priorities; and (3) the allocation of financial means to these rural development measures. The analysis is restricted to eight regions in the EU: four intermediate rural regions (Northern Netherlands, Lower Saxony, Wales and Emilia Romagna) and four most urban regions (Southern Netherlands, North Rhine-Westphalia, Flanders and Lombardia). It appears that the case study regions selected quite a large number of rural development measures from the menu, varying from 12 to 18. The analysis reveals that doubts can be raised whether all selected measures are according to the rural development priorities of the case study regions. In addition, it seems that rural development measures are sometimes interpreted in different ways by regions and that the relationship between the rural development measures and the three objectives of the second pillar is not unambiguous. Therefore, some reformulation of rural development measures and objectives of the second pillar is suggested at the end of this article. The findings of our analysis may serve as input in the debate on the future orientation of EU rural development policy.

The level of support provided to Russian agriculture, as measured by the Producer Subsidy Equivalent (PSE), may be used as a criterion to divide the period from 1986 to 1997 into three distinct phases: a phase of very extensive support during the Soviet period, a phase of negative at the beginning of the transition period and increasing in more recent years, with the exception of 1997 when the level of support fell again. It is highly likely that Russia’s PSE will fall again in 1998 as a result of the strong devaluation of the ruble in August 1998, further cuts in budgetary support for agriculture and some reductions in charges on food imports.

Since participation in agri-environmental programmes is voluntary, associated with opportunity costs (most of these programmes aim at reducing output), and financial compensation for participation is typically a fixed amount per hectare, a tendency is likely to arise for some sort of self selection: farms in favourable regions which face high opportunity costs from foregone output are less likely to participate than other, more disadvantaged farms. When trying to estimate the effects of such programmes on agricultural output, this self-selection bias can pose severe problems, as a direct comparison of participants with non-participants is likely to lead to erroneous results. This paper tries to highlight the effects of this self-selection process in the context of the Austrian OEPUL programme and its effects on grain yields. After identifying various sources of this problem, some possible remedies are presented and discussed. The empirical analysis is based on farm-level accounting data linked with the official agricultural support data (INVEKOS) for a sample of 1327 Austrian grain farms. Two years of data before (1993 and 1994) and one year (1997) after EU accession are utilized to estimate programme effects on grain yields.

This paper applies a semi-parametric approach to estimating a generalised model of investments in energy installations. The model accounts for irreversibility and lumpiness of investments by linking a parametric specification of the unobservable dynamic shadow price to observed investment behaviour using a non-parametric specification of the adjustment cost function. The results suggest that marginal costs of investments in energy installations increase quickly at small investment levels, whereas the increase slows down at higher investment levels. Therefore, standard parametric adjustment cost models are likely biased such that they over-estimate small investments and under-estimate large investments.

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.

Rural development has not received the priority and attention warranted by the present and future concentration of poverty in rural areas. Is this perhaps because rural development agencies present conflicting narratives? A framework is presented within which to answer that question, and is then applied to the recent policy statements of the EU, FAO, IFAD and the World Bank. Each policy statement is compelling in its own way, but the strategies are not consistent. A narrative is needed which: recognises the rapid pace of change in rural areas; acknowledges the overriding need for diversification out of agriculture; builds market institutions for growth; and works effectively within the current international consensus on poverty reduction, emphasising opportunity, empowerment and security.

This study aims at assessing the costs and benefits of multifunctional agriculture, and it is one of the very first studies using a quantitative approach to this new subject. The starting point is that if current farm subsidies are regarded as means to maintain the multifunctional characteristics of agriculture, what happens if subsidies are reduced. The effects of the decline in agricultural support on multifunctional characteristics of agriculture in Finland are estimated using the cost-benefit analysis (CBA). Only a part of the consequences can be assessed by the CBA due to lack of data on the economic value of many elements of multifunctional agriculture. Hence, the results should not be generalised too strongly, but they still provide useful information for the political decisionmaking.

Concerning further research, we should study, inter alia, what the so-called correct level of compensation for the adequate supply of public goods would be, and what kind of means of agricultural policy are the most efficient to unambiguously enhance the multifunctional character of agriculture.

This article presents results from an experiment into attribute perception and relevant levels for management of woodland and mountain areas typical of the Iberian Peninsula's Atlantic region. The aim, which the authors argue has been robustly reached, was to identify those aspects of forestry policy clearly perceived by citizens. This is useful for defining enlargement of areas protected under Natura 2000 Network. Results show clear preference for an increase in woodland to over half the current surface area, with replanting of traditional trees, in woodlands of low density and trees of different age and, preferably in irregular shaped plots.

Community based health insurance schemes are becoming increasingly recognized as an instrument which help farmers in rural areas of low income countries to better manage health. Health risks present a permanent threat to the income earning capacity of poor people. Beside direct economic cost for treatment and lost working time, indirect cost such as a reduction in labor supply materialize which increases the vulnerability of the household. It is often hypothesized that community based health insurance improve social protection, but quantitative analysis is largely missing. Against this background, this paper analyzes if members in a mutual health insurance scheme have a better access to health care than non-members taking “les mutuelles de santés” (mutual health organization) in rural Senegal as an example. Limited dependent and log linear regressions are used to capture the impact of health insurance on the probability of visiting a health care provider and the out-of-pocket expenditure at the point of use . The results of the analysis show that while community based health insurance schemes reach otherwise excluded people, the poorest of the poor in the communities are not covered. Regarding the impact on the access to health care, members have a higher probability of using hospitalization services compared to non-members and pay substantially less when they need care. Given the results from this study, community financing schemes have the potential to improve the risk management capacity of rural households.

A non-linear optimization model which maximizes total Ecuadorian social welfare, defined as the sum of Consumers’ and producers’ surpluses for the four major crops (corn, bananas, rice and African palm) is developed to evaluate the tradeoff between welfare and environmental degradation in Ecuador. It was found that a total welfare loss of US$122 million (a 11 percent reduction - from US$ 1.112 billion to US$ 989.66 million) would be expected from a 30 percent reduction in the total pesticide load on the environment in the production of the four major crops. The distributional impacts of the welfare loss were found, however, to be significantly skewed toward the loss of consumers’ surplus. Specifically, a 30 percent reduction of total pesticide load on the environment would result in a reduction of 3.86 percent of producers’ total surplus while consumers would be expected to loose 19.46 percent of their total surplus.

In this paper we measure the impact of an individual’s socioeconomic conditions on the decision to consume wine in a traditionally wine-producing area. Based on the data obtained in an exhaustive survey on wine consumption and through discrete choice models, we assess the changes which come about in the decisions to consume the different types of wine under consideration, and we obtain the most relevant distinctive and differentiated characteristics for each one of them.

This article is based on a socio-economic impact study of the introduction and adoption of tissue-culture (tc) technology in banana production in Kenya. It attempts to demonstrate that a prudent introduction and promotion of a new biotechnological innovation in farming can make a positive contribution to the socio- economic status of resource poor farmers in a developing country, such as Kenya. Adoption of tc technology in banana production in Kenya is considered a good example of biotechnological applications in agriculture. Hence the article hopes to make a contribution to recent debates at international levels as to whether biotechnology can make a difference in uplifting the living standards of people in the third world (Qaim, 1999; Graff, et al 2002; Qaim, et al 2002) by showing that it actually does so, using experiences from Kenya. The study utilizes both primary and secondary data sources. The results show that tc-banana production is relatively more capital intensive than non-tc banana production (re: about 70% fixed costs for tc banana versus about 49% fixed costs for non-tc banana). However, tc-banana production is found to offer relatively much higher financial returns than non-tc banana production. The high profitability of tc-banana production relative to traditional (non-tc) banana production and other farm enterprises in the pilot tc-banana project area in Kenya demonstrates the importance of biotechnological applications in rural development and shows that biotechnology can make a difference in uplifting the living standards of people in the third world. Therefore, efforts to promote tc-banana production in Kenya are justifiable from both food security and economic criteria.

In this paper, the Spanish demand for food away from home is analysed. A panel data set is built and appropriate techniques for estimating limited dependent variable models have been applied. Results indicate that where there are zero expenditures, these are largely due to infrequency of purchase rather than to abstention or to economic reasons. Furthermore, important differences appear among households. On the one hand, those households whose head is a highly-educated person, male, young and living on a salary in a large town are more likely to purchase food away from home. On the other hand, increases in income only provokes more than proportional increases in expenditure for those households headed by an unschooled person, a female or a person older than 55 and also for those households with more than half of its members older than 60 years.

Although soil fertility is recognized as a primary constraint to agricultural production in developing countries, use of fertilizer in Sub-Saharan Africa is declining. Smallholder farmers still rely heavily on livestock manure for soil fertility management. To explore the determinants of soil fertility management practices, including both the use of cattle manure and inorganic fertilizer, data are used from a sample of 3,330 geo-referenced farm households across Central and Western Kenya. A bivariate probit model is applied to jointly examine the use of the two technologies. Particular attention is given to measures of location related to market access and agroclimate, which in the adoption literature have typically been addressed using crude proxies. To avoid such proxies, GIS-derived variables are integrated into the household decision model. Their use also allows the spatial prediction of uptake based on parameter estimates. The results show clearly the derived-demand nature of soil fertility services, based on markets for farm outputs. They also illustrate that supply of manure for soil fertility amendments is conditioned by demand for livestock products, especially milk. The integration of GIS-derived variables is shown to better estimate the effects of location than the usual measures employed, and offers scope to wider use in technology adoption research.

In this paper we develop a dynamic data-consistent way for estimating agricultural land use choices at a disaggregate level (district-level), using more aggregate data (regional-level). The disaggregation procedure requires two steps. The first step consists in specifying and estimating a dynamic model of land use at the regionallevel. In the second step, we disaggregate outcomes of the aggregate model using maximum entropy (ME). The ME disaggregation procedure is applied to a sample of California data. The sample includes 6 districts located in Central Valley and 8 possible crops, namely: Alfalfa, Cotton, Field, Grain, Melons, Tomatoes, Vegetables and Subtropical. The disaggregation procedure enables the recovery of land use at the district-level with an out-sample prediction error of 16%. This result shows that the micro behavior, inferred from aggregate data with our disaggregation approach, seems to be consistent with observed behavior.
