The European Commission proposed the opportunity for individual EU Member States to restrict or prohibit the use of GMOs in food or feed on their territory (a national ‘opt-out’). The economic impact on individual sectors of the feed and food chain (the vegetable oil and meal industry, trade, animal feed industry, livestock sector) of a possible opt-out policy for soy by individual Member States has been assessed by LEI Wageningen UR.
A single scenario was defined in which the four countries France, Germany, Poland and Hungary choose an ‘opt-out’ policy for soy. Consequences of this switch to non-GM soy and substitutes were assessed both quantitatively and qualitatively for feed prices, for production costs for animal production, for crushing industry and for trade, with a focus on the medium term

The procedure for applying phosphorus (P) fertilizer to soil can be divided into three consecutive steps: (i) Measurement of soil-P availability, (ii) calibration of the soil-P fertility level and (iii) estimation of the recommended P dose. Information on each of these steps was obtained for 18 European countries and regions with the aim of comparing P fertilizer recommendation systems at the European scale. We collected information on P fertilizer recommendations through conventional or grey literature, and personal contacts with researchers, laboratories and advisory services. We found much variation between countries for each of the three steps: There are more than 10 soil-P tests currently in use, apparent contradictions in the interpretation of soil-P test values and more than 3-fold differences in the P fertilizer recommendations for similar soil-crop situations. This last result was confirmed by conducting a simple experimental inter-laboratory comparison. Moreover, soil properties (pH, clay content) and crop species characteristics (P responsiveness) are used in some countries in the calibration and recommendation steps, but in different ways. However, there are also common characteristics: soil-P availability is determined in all countries by extraction with chemical reagents and the calibration of the soil-P test values, and the fertilizer recommendations are based on the results from empirical field trials. Moreover, the fertilizer recommendations are nearly all based on the amount of P exported in the crops. As long as rational scientific and theoretical backgrounds are lacking, there is no point in trying to synchronize the different chemical methods used. We therefore call for a mechanistic approach in which the processes involved in plant P nutrition are truly reproduced by a single standard method or simulated by sorption-desorption models.

The skill of the land surface model HTESSEL is assessed to reproduce evaporation in response to land surface characteristics and atmospheric forcing, both being spatially variable. Evaporation estimates for the 2005 growing season are inferred from satellite observations of the Western part of Hungary and compared to model outcomes. Atmospheric forcings are obtained from a hindcast run with the Regional Climate Model RACMO2. Although HTESSEL slightly underpredicts the seasonal evaporative fraction as compared to satellite estimates, the mean, 10th and 90th percentile of this variable are of the same magnitude as the satellite observations. The initial water as stored in the soil and snow layer does not have a significant effect on the statistical properties of the evaporative fraction. However, the spatial distribution of the initial soil and snow water significantly affects the spatial distribution of the calculated evaporative fraction and the models ability to reproduce evaporation correctly in low precipitation areas in the considered region. HTESSEL performs weaker in dryer areas. In Western Hungary these areas are situated in the Danube valley, which is partly covered by irrigated cropland and which also may be affected by shallow groundwater. Incorporating (lateral) groundwater flow and irrigation, processes that are not included now, may improve HTESSELs ability to predict evaporation correctly. Evaluation of the model skills using other test areas and larger evaluation periods is needed to confirm the results.

The effects of multiple applications of hydrophobic kaolin particle film on apple orchard bug (Heteroptera), beetle (Coleoptera) and spider (Araneae) assemblages were studied in the Netherlands. Insecticide-free orchard plots served as a control. The kaolin applications significantly reduced the abundance and species richness of the communities and also altered their composition and diversity. The treatments disrupted many non-target groups notably mycophagous, predacious and tourist beetles, zoophagous bugs and spiders. Among spiders, wanderer spiders (Thomisidae, Philodromidae) were most affected, whereas web building spiders (Dictynidae) were least affected. After ceasing the applications in July, the between-treatment differences in composition of all communities and diversity of heteropterans and spiders diminished while the differences in abundance and species richness remained for a long time, until the end of September. Many predator species with good colonisation ability recovered slowly after the treatments, mainly due to the scarcity of prey.

Het centrale thema van mijn onderzoek is aanpassing aan klimaatverandering in rivierstroomgebieden. De wetenschappelijke literatuur over aanpassing aan klimaatverandering besteedt veel aandacht aan klimaateffecten, kwetsbaarheid en barrières voor aanpassing. Veel minder is bekend over de voorwaarden die het mensen mogelijk maakt zich in de praktijk aan te passen. Begrip van deze voorwaarden is echter van cruciaal belang voor het duurzaam realiseren van klimaataanpassing. Deze studie conceptualiseerde aanpassing aan klimaatverandering als het proces waarin actoren strategieën ontwikkelen en implementeren om een bepaalde doelstelling te halen. Wat betreft participatie, bevestigde de Hongaarse studie, dat samenwerking in de beleidsvoorbereiding ten goede kwam aan de eensgezindheid en het begrip tussen partijen.

This paper looks at the role of individuals and the strategies that they use to bring about or oppose major policy change. Current analysis of the role that individuals or small collectives play in periods of major policy change has focussed on strategies that reinforce change and on the supporters of change. This paper adds the perspective of opponents, and asks whether they use similar strategies as those identified for supporters. Five strategies are explored: developing new ideas, building coalitions to sell ideas, using windows of opportunity, playing multiple venues and orchestrating networks. Using empirical evidence from Dutch and Hungarian water policy change, we discuss whether individuals pursued these strategies to support or oppose major policy change. Our analysis showed the significance of recognition of a new policy concept at an abstract level by responsible government actors, as well as their engagement with a credible regional coalition that can contextualise and advocate the concept regionally. The strategies of supporters were also used by opponents of water policy change. Opposition was inherent to policy change, and whether or not government actors sought to engage with opponents influenced the realisation of water policy change.

This paper analyzes total factor productivity (TFP) growth in agriculture for the ten Central and East European countries (CEECs) that began formal negotiations for EU accession in September 1998. A panel data set is constructed consisting of pooled time series data for the ten CEECs from 1993 to 2002, and it is used to estimate a time-varying stochastic production frontier. A Malmquist index of TFP growth is estimated and decomposed into efficiency change and technical change. The results show that despite the fall in output, TFP growth rates were positive for all ten CEECs. This suggests that the collapse of agricultural output in the CEECs is not necessarily a good indicator of agricultural performance. An analysis that only focuses on output decline provides a partial and misleading interpretation of the success of agricultural reforms. Also, estimates of technical efficiency confirm the hypothesis that large-scale farming performs better than small-scale farming when markets are missing and economic conditions are uncertain.

Dit vergelijkend onderzoek behandelt de Natura 2000 gebiedsbescherming van de Vogel- en Habitatrichtlijn langs de kernthema¿s van imago, implementatie, interpretatie en integratie van Natura 2000 gebieden. Na een zoektocht naar relevante kwesties in 25 lidstaten werden vijf landen geselecteerd voor nader onderzoek, te weten: Verenigd Koninkrijk, Zweden, Spanje, Frankrijk en Hongarije. Na een zestal leerervaringen wordt onder meer geconcludeerd dat een casuïstische benadering de meeste kansen beidt en een omgevingswet niet noodzakelijkerwijs leidt tot één integrale omgevingsvergunning

This report describes the major result of a research project funded by the INCO-Copernicus programma of European Commission under Contract number ERB-IC15-CT98-0133. The study focused on the long-term environmental risk of soil acidification on: (i) mobilisation and leaching and (ii) plant uptake of potentially toxic heavy metals (i.e. lead, cadmium, zinc and copper) from well-drained agricultural soils in Slovakia and Hungary. The research was mainly carried out in the period 1998-2001, but there was a strong delay in the final reporting of the results as summarised in this report. This report includes the major papers resulting from this study. The major result obtained from the various studies is that transfer functions and soil-to-plant transfer relationships, allowing the calculation of dissolved metal concentrations and plant meta contents from soil metal contents accounting for differences in soil properties, such as pH and organic matter content, in the solid phase, are practical and reasonably reliable approaches for use in regional risk assessments, as carried out for Hungary and Slovakia.
