Stakeholder participation is becoming increasingly important in water resources management. In participatory processes, stakeholders contribute by putting forward their own perspective, and they benefit by enhancing their understanding of the factors involved in decision making. A diversity of modeling tools can be used to facilitate participatory processes. Bayesian networks are well suited to this task for a variety of reasons, including their ability to structure discussions and visual appeal. This research focuses on developing and testing a set of evaluation criteria for public participation. The advantages and limitations of these criteria are discussed in the light of a specific participatory modeling initiative. Modeling work was conducted in the...

Water Management in Spain: the Role of Policy Entrepreneurs in Shaping Change
Provedor de dados: 7
The role played by policy entrepreneurs in preparing, initiating, and implementing water policy change in Spain over the last two decades is examined in an effort to understand how transitions in water management occur. The main questions considered are whether policy entrepreneurs can influence water policy change, and which strategies they actually adopt to promote change. John Kingdon's multiple streams framework was used to assess the ways in which policy entrepreneurs succeed in challenging the dominant agenda, mobilizing alternative policy ideas, and making use of multiple venues for initiating policy change. The data set comprises secondary documentation and interviews with state and non-state actors involved in Spanish water management. The main...

The Systems Approach Framework as a Complementary Methodology of Adaptive Management: a Case Study in the Urban Beaches of Barcelona
Provedor de dados: 7
The Systems Approach Framework is a methodological framework designed to enhance the efficacy of human decision-making processes within social-ecological systems with regard to sustainability. The objective of resilience adaptive management is to either maintain the system within the current regime such that the desired ecosystem goods and services continue to be delivered, or to move the system phase to a preferred regime. Although the objectives of the two frameworks are not exactly the same, there are considerable complementarities between them. Through application of the Systems Approach Framework in a case study regarding the urban beaches of Barcelona, Spain, we present some of the main findings revealed during the model construction and stakeholder...

Influence de l'azote et du phosphore sur la croissance et la toxicité de Prorocentrum lima (Ehrenberg) Dodge
Provedor de dados: 5
Autores: Morlaix, Martine; Lassus, Patrick.
Very few attempts have been made in order to investigate the role of nutrients on cellular growth and toxin production in dinoflagellates associated with DSP (Diarrhetic Shellfish Poison). Some preliminary results are presented here, aiming at a better knowledge of inorganic nitrogen and organic phosphorus effects upon division rate and toxin content of Prorocentrum lima (PL2V spanish strain). Nitrogen have a positive effect on growth rate, up to a threshold value of 880muM.l-1. Above this threshold the rate decreases. There is no effect on toxin content since okadaic acid and DTX1 cell contents remain low (4.8 +/- 0.5 pg.cell.-1) and steady. Phosphorus effect upon division rate follows a non-linear relationship, whereas cellular toxic content is inversely...

La culture suspendue de Chlamys varia , de la nourricerie a la taille commerciale, en Galice (Espagne)
Provedor de dados: 5
Autores: Cancelo, M; Guerra, A; Fernandez, A; Gabin, C; Fernandez, J.
Chlamys varia has a great potential of culture in Galicia, and it is likely to be among the pectinids, both a complement and an alternative to raft mussel culture which is dominant in the region. The present work attempts to analyse the growth of nursery spat of 6.46 plus or minus 0.75 mm reared in a raft during fifteen months in different depth and densities. The final average height is between 36.49 plus or minus 0.56 mm in the group of high density in the bottom and 40.75 plus or minus 0.55 mm in those of low density at the surface. Different culture densities have shown significant differences in growth (p &lt; 0.001). However, different depths have not shown such differences. At the end of this period mortality is lower than 2% in all groups.

Speciation in Cyprinidae of the Iberic Peninsula.
Provedor de dados: 5
Autores: Almaca, Carlos.
Coming from Oriental Asia and Siberia, the Cyprinidae reached the Iberic Peninsula probably at the end of the Oligocene. Their populations bore speciation processes which led to the formation of a fauna rich in endemic species and subspecies. Populations of two of the genera Barbus and Pseudophoxinus reached Northwestern African forming there several endemic species. Concerning the speciation forms, it is probable that the allopatric form, whether by foundation effect or by subdivision, played an important part. Pyrenees and Mediterranean Sea settled probably efficient barriers for the Iberic Cyprinidae isolation. The present geographical repartition of Cyprinidae in Iberic Peninsula suggests that altitude lines and glaciations which reached the north of...

Brachiopods from the Valdeteja Formation (Pennsylvanian; Cantabrian Mountains, NW Spain)
Provedor de dados: 16
Autores: Martínez Chacón, M.L.; Winkler Prins, C.P.
After a short introduction on the lower Pennsylvanian (Bashkirian to lowermost Moscovian)Valdeteja Formation in its stratigraphical context, an overview of its brachiopod faunas is presented and their palaeoecological and palaeogeographic importance discussed. Two new genera of the Strophalosiidina, showing adaptations to a reef environment, are described. The genus Ovetina (type species O. truyolsi gen. et sp. nov.) is an aulostegid with a well developed ventral flange. Miroproductus (type species M. posadai gen. et sp. nov.) is an early richthofenioid, probably derived from an aulostegid such as Institina MUIR-WOOD &amp; COOPER, 1960.

Phylogeny and biogeography of midwife toads (Alytes, Discoglossidae): a rebuttal
Provedor de dados: 16
Autores: Arntzen, J.W.; García-París, M.
Three competing phylogenetic hypotheses for the genus Alytes (midwife toads) are evaluated. Based on quantitative coding of protein characters the most parsimonious solution shows a sister taxon relationship for Alytes dickhilleni and A. muletensis. The alternatives in which A. obstetricans has its sister group in either A. dickhilleni or A. muletensis lack support. Using calibrations derived from protein evolutionary rates, the vicariant events giving rise to A. obstetricans and the lineage leading to the A. muletensis and A. dickhilleni clade and the subsequent splitting between A. muletensis and A. dickhilleni cannot be placed much earlier than the Miocene-Pliocene boundary. Biogeographical scenarios invoking an earlier time of divergence should be...

Pseudocriboconcha prinsi gen. et sp. nov. (Ostracoda) from the late Mississippian (Carboniferous) of the Cantabrian Zone (northern Spain)
Provedor de dados: 16
Autores: Sánchez de Posada, L.C.; Sanz-López, J.
A new ostracod found in the Mississippian of the Cantabrian Mountains shows ornamental features similar to Criboconcha Cooper, hitherto known from Mississippian and Pennsylvanian strata of different parts of the world (especially from the U.S.A.). However, some features of this ostracod are very different from the typical characteristcs of the Healdiidae and support bairdiocyproidean affinities. The new genus Pseudocriboconcha (type species Pseudocriboconcha prinsi sp. nov.) is proposed. This species is distinguishedby distinct pits on the lateral surface; a posterior ridge ending in dorsal and ventral spines; a rounded rim parallel to the borders of each valve; and a spine on this rim, above the anterior end and directed dorsally or anterodorsally.

Considerations on most Rugosa and the Dividocorallia from de Groot’s (1963) collection
Provedor de dados: 16
Autores: Fedorowski, J.
Rugose corals reinvestigated herein constitute the main part of the collection described by de Groot (1963). The taxonomy proposed herein differs in several instances from that accepted originally by de Groot. Some changes, such as Petalaxis for Lithostrotionella and Calophyllum instead of Polycoelia, were already introduced in de Groot’s unpublished catalogue. Others were introduced in order to match the recent advances in rugose coral systematics. Most systematic changes were based on new microstructural, diagenetic and hystero-ontogenetic studies. These are described in detail for individual species and briefly discussed in the concluding considerations. Trabecular microstructure of septa and its diagenetic alteration was documented for most species....

Morphological and allozyme studies of midwife toads (genus Alytes), including the description of two new taxa from Spain
Provedor de dados: 16
Autores: Arntzen, J.W.; García-París, M.
Allozyme variation in 31 to 50 presumptive loci of 12 populations of European midwife toads of the genus Alytes show appreciable genetic divergences (DiNe from 0.29 to 0.72) among four groups. These groups correspond to A. cisternasii Boscá, 1879, A. obstetricans (Laurenti, 1768), A. muletensis (Sanchiz &amp; Adrover, 1979), and a new species from the Betic mountains described here as A. dickhilleni n. sp. Smaller divergences among geographic groups of populations of A. obstetricans (up to DNei = 0.17) support the existence of three geographic units in Europe corresponding to the previously recognized subspecies A. o. obstetricans and A. o. boscai Lataste, 1879, plus a third one described here under the designation of A. o. almogavarii n. ssp.

Provedor de dados: 16
Autores: Gittenberger, E.
To provide background information for a proposal to the International Commission on Zoological Nomenclature to suppress five subjective senior synonyms of Trochoidea geyeri, the synonymies of this and some other hygromiid species are given. The nominal taxa that are dealt with concern species that are conchologically more or less similar. These species were studied to minimize the risk that even more unused senior synonyms of T. geyeri would be discovered, which would require an additional ruling of the Commission. Distributional data and short conchological diagnoses are added to increase the usefulness of the present paper.

Isopodes Aselloïdes stygobies d’Espagne récoltés par J. Notenboom et I. Meijers, III — Le genre Proasellus: A — Espèces oculées ou microphtalmes
Provedor de dados: 16
Autores: Henry, Jean-Paul; Magniez, Guy.
Samples collected in underground waters of Spain by Ine Meijers and Jos Notenboom demonstrated the presence of some oculated asellids previously known: Proasellus coiffaiti, P. coxalis, and P. meridianus, and also four new stygophilous species, more or less depigmented, with different stages of regression of the ocular system: P. beticus n. sp., P. ortizi n. sp., P. aragonensis n. sp., and P. ebrensis n. sp. These forms represent relict populations of ancient epigean species. The anophthalmous species of the Aquitanian Basin, Pyrenees, and Iberian Peninsula are more closely related to P. beticus and P. ortizi than to the Recent epigean species P. coxalis and P. meridianus.

Microdyromys (Gliridae, Rodentia, Mammalia) from the Early Oligocene of Montalbán (Prov. Teruel, Spain)
Provedor de dados: 16
Autores: Freudenthal, M.; Martín-Suárez, E.
A new species of Microdyromys, M. puntarronensis, is described from the Early Oligocene locality Montalbán 8 (Teruel, Spain). It is compared with the other Early Oligocene species of the genus, M. misonnei. The latter is known from Hoogbutsel (Belgium) and Montalbán 1D. Montalbán 8 is intermediate in age between Hoogbutsel and Montalbán 1D, and the dental pattern of its Microdyromys is more advanced than it is in Montalbán 1D. This leads to the conclusion that two lineages of Microdyromys existed in the Early Oligocene. An attempt is made to follow these lineages throughout the Late Oligocene and the Miocene.

Correlates between morphology, diet and foraging mode in the Ladder Snake Rhinechis scalaris (Schinz, 1822)
Provedor de dados: 16
Autores: Pleguezuelos, J.M.; Fernández-Cardenete, J.R.; Honrubia, S.; Feriche, M.; Villafranca, C.
In many vertebrates, foraging mode (active versus sit-and-wait) is tied to some traits of their natural history such as morphology, type of prey, rate of food acquisition, and survival rate. We explore the correlates between some morphological traits of a Mediterranean colubrid and its feeding ecology and the predation risk, by comparing data on teeth number, tail damage, and diet. A large sample (n = 368) of the Ladder Snake, Rhinechis scalaris is used. The species feeds almost exclusively on endotherms, mainly mammals (nearly 95% of the diet in mass), which set R. scalaris among the most stenophagous snakes in the western Palaearctic. There is also a high percentage of motionless prey in the diet (up to 50% in prey mass), such as nestling birds, mammals...

Autores: Nayrolles, Pierre.
The following three species are redescribed: Sminthurus viridis (Linnaeus, 1758), Sminthurus nigromaculatus Tullberg, 1871, and Sminthurus multipunctatus Schäffer, 1896. Four new species are described from France and Spain: Sminthurus bourgeoisi n. sp., Sminthurus bozoulensis n. sp., Sminthurus leucomelanus n.sp.,and Sminthurus hispanicus n. sp. The importance of the ontogeny of chaetotaxy is stressed. Indeed, not all species acquire the secondary chaetotaxy in the same instar, and for these characters the most informative instar is not the adult but the third juvenile instar. The study of such characters involves the clustering of similar characters. A short discussion is given about this issue (selection of characters and clustering criteria).

Autores: Winkler Prins, C.P.
After a short introduction on the reef development during the Late Palaeozoic, the tectono-stratigraphic history of the Cantabrian Mountains (northern Spain) during the Carboniferous is discussed, with an emphasis on the tectonically active Pennsylvanian (i.e., Late Carboniferous). The reef-bearing Valdeteja, San Emiliano, and Cuera formations are briefly described, and their brachiopod faunas are discussed with special emphasis on adaptations to a reef environment. The brachiopod faunas are compared with similar faunas from carbonate-platform deposits with reef structures of Mississippian (i.e., Early Carboniferous) age from Northwest Europe (the British Isles in particular), with Pennsylvanian-Permian faunas from the Alps, Urals, Spitsbergen and Arctic...

Autores: Sanz, Sebastián; Platvoet, Dirk.
On several occasions, shrimps belonging to a new species of the genus Typhlatya were collected in a cave in the province of Castellón, Spain. This is the first record of the genus in the Iberian Peninsula. The species is described and the validity, distribution, and zoogeography of the genus, as well as the status of the genus Spelaeocaris, are discussed. Former models for the evolution of the genus Typhlatya and its genus group are reviewed, as well as the system of inner classification of the Atyidae and its biogeographical meaning. For the age and evolution of the genus we developed a new model based on vicariance principles that involves further evolution of each species after the disruption of the ancestral range. This allows new estimations for the...

Insectivore faunas from the Lower Miocene Anatolia. Part4: The genus Desmanodon (Talpidae) with the description of a new species from the Lower Miocene of Spain
Provedor de dados: 16
Autores: Hoek Ostende, L.W. van den.
A review is given of the literature on Desmanodon and Paratalpa. These two talpid genera can only be identified on the basis of the morphology of the humerus. Two species of Desmanodon, D. ziegleri n.sp. and D. burkarti n.sp., are described from the Lower Miocene of Anatolia. These species are considered ancestral to the Middle Miocene species of Anatolia. D. ziegleri is also a likely ancestor for the European species of Desmanodon. Desmanodon daamsi n. sp. is described from the Lower Miocene of Spain. The Desmanodon/Paratalpa finds from the Calatayud-Teruel basin (Spain) are discussed.  The tribal classification of Desmanodon is problematic, since some species resemble Urotrichini, whereas other are morphologically closer to Scalopini. This suggests that...

La evolución de la Agriculura ecológica (AE), ha sido distinta incluso dentro de los países industrializados, generándose desde motivaciones y fundamentos distintos en los movimientos que la forjaron. Esto ha ocasionado distintos énfasis en sus objetivos, principios y valores que, luego han marcado el desarrollo de la misma. Este es el caso de España, donde el movimiento social e ideológico que estimuló el nacimiento y práctica de la AE puso mayor énfasis en los aspectos sociopolíticos, en detrimento quizá de los aspectos relacionados con el desarrollo de los mercados, lo que más adelante ha repercutido en su desarrollo, junto a otros factores tales como el escaso interés y apoyo gubernamental al sector o el menor desarrollo del sector industrial, con el...

Autores: Chamorro, Lourdes; Armengot, Laura; José-María, Laura; Sans, F. Xavier.
The Area of Natural Interest of Gallecs (ANIG) is one of the largest areas of arable land managed organically in Catalonia. In 2005 a project was launched to convert fields to organic farming and recuperate traditional crop varieties. The aim of this work is to analyse the changes in diversity of the weed flora, including segetal and rare species, and of crops in 20 fields (ca. 50 ha) after the conversion to organic farming during 5 cropping periods (2005-2010). Number of cultivated crops has increased from 1 to 17 including ancient and local varieties of cereal and legumes. Weed biodiversity increased by a 50% in five years at field and regional scale. Crop rotations and sowing organic seeds from other farmers can contribute to the increase and the...

The turnover of the EU agri-food sector overtops 2,000 billion Euros a year and employs roughly 22 millions workers. The focus of this paper is on the sectors directly linked to agricultural production and the food industry. Having a comprehensive understanding of extended agri-food economic linkages is critical when designing pertinent policies to deliver the full potential of strong EU agri-food and other bio-based sectors. A more disaggregated view is required. This study stars from a Social Accounting Matrices (SAM) for Spain with a highly disaggregated agricultural sector (AgroSAMs) for the year 2000. This study uses the AgroSAMs in its entire disaggregation, in order to provide a descriptive analysis of the agri-food and bio-based sectors. The limits...

Prospective Trends in Wine Export Markets – Expert Views from Spain
Provedor de dados: 31
Autores: Bardaji,   Isabel; Mili,   Samir.
As in other European producing countries, the wine industry in Spain faces growing competition from New World producers. International competitiveness of Spanish and European wines has been affected by increasing supply, declining public support, saturated domestic demand and increasingly quality-driven markets. Resolving the derived wine competitiveness crisis would require production rationalisation and adaptation to changing commercial and demand requirements, through new productive processes and strategies for further opening of foreign markets. The purpose of this paper is to explore main current and future trends affecting the global wine market and their consequences from the Spanish perspective. After identifying the world wine market’s main...

Old World Wines Revisited: Consumers' Valuation of Spanish and German Wines in the UK Wine Market
Provedor de dados: 31
Autores: Steiner,   Bodo E.
The mid 1990s was a pivotal period for the UK retail wine market, as New World Wines started to expand significantly at the expense of Old World Wines. This paper reviews supply and demand-side characteristics of the UK wine market during this period, and the underlying wine labeling scheme, before assessing how wines from Old World wine producing countries were valued by consumers in the British wine market. Following a more detailed discussion of econometric estimation issues, hedonic price analysis is applied in order to analyze consumers’ valuation of wine label attributes of Spanish and German wines sold in Britain in 1994.

Agricultural trade liberalisation in the Doha Round: impacts on Spain
Provedor de dados: 31
Autores: Philippidis,   George.
Whilst there is a growing literature of computable general equilibrium (CGE) studies examining the impacts of the current Doha Proposals, estimates for the EU are highly aggregated (i.e., EU15). Employing a detailed baseline scenario and a plausible Doha outcome, we examine the long run costs for the European Union, in particular focusing on Spain. Moreover, we implement recent CAP reforms through explicitly modelling of CAP mechanisms to provide greater credibility in assessing the long run asymmetric budgetary and welfare impacts on EU member states. Our estimates forecast resource substitution effects between Spanish agro-food sectors and resource shifts from agro-food activities into manufacturing and services production. In Spain, the impacts of...

Spanish Consumers' Attitudes and Acceptability towards GM Food Products
Provedor de dados: 31
Autores: Angulo,   Ana Maria; Gil,   Jose Maria.
The objective of this paper is to analyse consumers’ attitudes and acceptability of GM food products in Spain. From the methodological point of view, a three-equation model of consumer behaviour is estimated assuming a kind of causal chain among the degree of knowledge, attitudes and buying intentions. Explanatory variables include socioeconomic characteristics of respondents as well as endogenous variables of the previous equations. The model provides a better knowledge of how attitudes and buying intentions towards GM food are formed. Higher educated consumers, more concerned about labelling information and less about price, and regular buyers of organic foods show a higher (not necessarily better) knowledge on GM technology and its consequences....

The analysis of asymmetries in the price transmission mechanism at different levels of the marketing chain provides some interesting information about the degree of competition in vertical related markets. The objective of this paper is to investigate the non-linear adjustments of prices along the lamb sector in Spain. The methodology used is based on the multivariate approach to specify and estimate a Threshold Autoregressive Model. Price relationships at farm, wholesale and retail levels are considered. Results indicate that in the long-run price transmission is perfect and any supply or demand shocks are fully transmitted to all prices in the system. In the shortrun, analyses suggest that the high degree of horizontal concentration among retailers allow...

Taste Changes and Demographic in Spanish Seafood Consumption
Provedor de dados: 31
Autores: Millan,   Joaquin A.; Aldaz,   Natalia.
This study analyses seafood consumption at home in Spain using three different cross-sectional survey data-sets for 1980, 1990 and 1998.  Households are analysed in eleven different types, according to size and composition.  Price indices for seafood and meats are calculated for each household type.  Discrete participation and continuous consumption decisions are studied.  Socio-economic variables sometimes play an important role but not with a regular pattern.  Economic fundamentals follow a common pattern for all household types.  Seafood demand is inelastic in 1980 and very elastic and meat complement in 1990 and 1998.  Expenditure elasticity does not decrease between 1980 and 1998.

Do defaults matter? Willingness to pay to avoid GM food vis-à-vis organic and conventional food in Denmark, Great Britain and Spain
Provedor de dados: 31
Autores: Costa-Font,   Montserrat; Tranter,   Richard B.; Gil,   Jose Maria; Jones,   Philip J.; Gylling,   Morten.
The introduction and communication of new technologies in the food industries has given rise in the past to some scientific uncertainty that hampers informed choice. Here we draw upon the case of Genetically Modified (GM) technology and, in particular, on different types of GM food, to investigate consumers’ behavioural reactions to GM food as well as their willingness to pay for avoiding GM food in three EU countries, Denmark, GB and Spain in 2007. Our unique contribution lies in that our empirical analysis concerns two food products containing different characteristics. In particular, we compare consumers’ reactions to cornflakes (to represent a processed food) and tomatoes (to represent a 'fresh' food) juxtaposed with GM and conventionally produced...

Spanish Wine Consumer Behaviour: A Stated and Revealed Preferences Analysis
Provedor de dados: 31
Autores: Nadhem,   Mtimet; Miguel,   Albisu Luis.
Overall wine consumption in Spain is decreasing while, at the same time, Designation of Origin (DO) wine consumption is increasing gradually. This study examines Spanish DO wine consumer behaviour through stated preferences (SP) and revealed preferences (RP) data. Part-worth utilities are calculated and results from both analyses are compared to look for similarities and differences between what respondents say on surveys and what they really do on real purchases. Consumer segmentation is undertaken based on purchase frequencies. In a second step, we try to pool the two data sources in order to get more meaningful and robust results. Results indicate similarities in the consumer choice process when comparing the two data sources, especially for the...

The Determinants of Survival of Spanish Consumers Fronting the BSE Crisis
Provedor de dados: 31
Autores: Radwan,   Amr; Gil,   Jose Maria; Serra,   Teresa.
The impact of food scares on meat consumption has been traditionally investigated by estimating food demand systems using aggregated time series. Only a few have considered micro data but none of them has tried to quantify consumers’ reaction to food scares and the speed of such reactions. In this study we apply duration analysis techniques with the aim of analysing the effect of different explanatory variables on both the risk of reducing beef consumption and the timing of this reduction. Our results suggest that the maximum hazard occurs during the few months after the occurrence of the food crisis and then the reducing consumption hazard tend to diminish. Moreover, economic factors such as prices and income could be considered as the most determinant...

The Impact of Price Intervention Policies to Improve Dietary Quality in Spain
Provedor de dados: 31
Autores: Gil,   Jose Maria; Angulo,   Ana Maria; Mtimet,   Nadhem.
Many commentators have claimed that farm subsidies have contributed significantly to the “obesity epidemic” by making fattening foods relatively cheap and abundant and, symmetrically, that taxing “unhealthy” commodities or subsidizing “healthy” commodities would contribute to reducing obesity rates. This paper makes three contributions. First, we review evidence from the literature on the impacts on food consumption and obesity resulting from subsidies applied in the past to production or consumption of farm commodities. Second, we develop and present new arguments and preliminary evidence on the impacts of past government investments in agricultural R&amp;D on food consumption and obesity—through research-induced increases in agricultural productivity and...

Co-operative Bank System: The Spanish Case
Provedor de dados: 31
Autores: Navarro,   Amparo Melian.
In practically all European countries, co-operative credit societies have evolved towards a system which is comparable to other financial groups. This paper explores the recent evolution of Spanish credit co-operatives and especially rural savings banks. The creation of "Group Caja Rural" in 1989, has meant the greatest commitment to the integration of Spanish credit co-operatives in the face of the challenges of economic globalisation and the great changes in the national and international financial system. The running of this Group is through a vertebrate structure, in co-ordination and representation aspects as well as in operative functions.

Environmental and socioeconomic impact of the new cotton reform
Provedor de dados: 31
Autores: Arriaza Balmón,   Manuel.
Following the decoupling of the cotton subsidies in 2006 the production system has become less intensive in input usage with an average yield reduction of 40 per cent. Albeit the farm income has not been reduced, the reform has had a negative effect on the economy of some rural areas of Southern Spain, where there are few productive alternatives to cotton, with a 39% reduction of direct farm labour. Besides, the reform has been borne by the ginning industry (60% reduction), the agrochemical suppliers and the auxiliary sector. On the other hand, the environment has benefits from the extensification of the cotton production since three quarter of the production is now carried out under integrated production that implies a reduction in the amount of...

Autores: Santos,   Maria del Valle; Garcia,   Maria Teresa; Ortega,   Ana Maria.
The present study is framed within recent works addressing the process of product portfolio renewal as a mechanism for organizational renewal, in that firms may use it to meet the challenge of a changing environment. Based on this theory, we build an analysis model linking product portfolio renewal to changes in external factors and apply it to D.O. wine companies in Castilla y León. We found that both the environment as well as firms themselves had been highly dynamic during the period analyzed vis-à-vis their product portfolios. The importance of issues related to organizational adaptation and adjustment, such as those tackled in our research, lies in their link to organizational survival, making them a focal point of managerial concern. The findings to...

Viability of the Raw Cotton Production in Spain After the Decoupling of the Subsidies
Provedor de dados: 31
Autores: Arriaza Balmón,   Manuel; Gomez-Limon,   Jose Antonio; Gonzalez,   Jose; Ruiz,   Pedro.
Considering the latest reform of the EU's Cotton Regulation of 29th April 2004, which will come into force in the 2006/07 season, we analyse its impact on the cotton production sector of Andalusia. The decoupling of subsidies implies that producers will be entitled to 65 percent of the amount received in the reference period (three years) irrespective of the crop chosen to grow. The remaining 35 percent (slightly higher) is paid as cotton are a payment. In this research, first from a survey carried out in 2004 we obtained six groups of producers using fact or analysis and cluster analysis. Then, based on this characterization, we assess the impact of two policy scenarios: (a) the implementation of the reform without any additional measures, and (b) the...

Revisiting the demand of agricultural insurance: The case of Spain
Provedor de dados: 31
Autores: Garrido,   Alberto; Zilberman,   David.
We use the actual insurance records of 52,300 farmers and 11 years to estimate two sets of insurance demands. We define measures of insurance's expected returns, variance and third moment, based on observed insurance data, and infer the expected returns for those farmers that have never had an indemnity. We estimate several probit models and count models for the insuring vs non-insuring strategies, in which the economic returns of insurance and its two measures of dispersion enter as explanatory variables. Results show that farmers' insurance strategies are largely explained by their actual insurance experience as captured by these three variables. Individuals with loss rations greater than 1 do not show more responsiveness that those facing more balanced...

Effects of the decoupling of the subsidies on agricultural water productivity
Provedor de dados: 31
Autores: Lorite,   I.J.; Arriaza Balmón,   Manuel.
In this work several performance indicators such as the Annual Relative Irrigation Supply (ARIS) and the Irrigation Water Productivity (IWP), have been considered to evaluate the changes in the cotton irrigation management due to the decoupling of the European Union Subsidies. For this purpose, a modern irrigation scheme, the Genil–Cabra Irrigation Scheme (GCIS) located in Southern Spain, has been selected. The total irrigated area is 6,900 ha with wheat, olive and cotton as the main crops. The irrigation season 2004/05 was the period when the crop pattern and water management trend changed dramatically. From this year to the present the area cultivated with crops with high water requirements like cotton, sugar beet and maize has been reduced almost by...

Farm Structure and the Effects of Agri-Environmental Programs: Results from a Matching Analysis for European Countries
Provedor de dados: 31
Autores: Pufahl,   Andrea; Weiss,   Christoph R.
This paper extends previous research (Pufahl and Weiss, 2009) and applies a semi-parametric propensity score matching approach to evaluate the effects of agrienvironment (AE) programs on input use and farm output of individual farms in eight Member States of the European Union. We find substantial differences in treatment effects between countries. The analysis reveals significant effects of AE participation on production (Germany, France) and farm profits (France, Ireland, United Kingdom). AE participation sporadically reduces the intensity of land use as measured by the purchase of farm chemicals (fertilizer, pesticide) and grazing livestock densities. We also find differences in the treatment effect among farms with different farm size (heterogeneous...

Asymetric Price Transmission in the Spanish Lamb Sector
Provedor de dados: 31
Autores: Ben Kaabia,   Monia; Gil,   Jose Maria.
This paper aims to investigate the non-linear adjustments of prices between farm and retail prices in the lamb sector in Spain. The methodology used is based on the multivariate approach to specify and estimate a three-regime Threshold Autoregressive Model. Results indicate that in the long-run price transmission is perfect and any supply or demand shocks are fully transmitted along the marketing chain. In the short-run, price adjustments between the farm and the retail levels are asymmetric and are representative of a demand-pull transmission mechanism. On the other hand, retailers benefit from any shock, whether positive or negative, that affects supply or demand conditions.

CAP Reform and the Mediterranean EU-Member States
Provedor de dados: 31
Autores: Borresch,   Rene; Kavallari,   Aikaterini; Schmitz,   P. Michael.
In the previous years the Mediterranean Member States of the EU came across the Reform of the CAP and especially last year faced the second wave of the Reform for three typical Mediterranean products, namely cotton, olive oil and tobacco. In this paper a partial equilibrium model is used to simulate the impacts of decoupling, as a key point of the decided CAP Reform. The second wave of the Reform appears to be of crucial importance for the southern EU countries and although the producer's income is reduced, there are positive welfare effects.

The objective of the paper is to investigate the impact of co-operation amongst stakeholders of the food chain on enterprise competitiveness. The analysis focuses on the Spanish wheat to bread chain. A theoretical model is developed which covers the main components that define competitiveness (profitability, turnover, market share, customer loyalty and product quality), quality supply chain relationship (trust, commitment and satisfaction) and the main factors explaining supply chain relationship (i.e. quality and frequency of the communication, personal bounds, etc.). The Spanish wheat to bread supply chain has been chosen to empirically test the model. This sector is very fragmented all along the chain, with a high number of wheat farmers, millers and...

Non-parametric and Parametric Modeling of Biodiesel - Sunflower Oil - Crude Oil Price Relationships
Provedor de dados: 31
Autores: Hassouneh,   Islam; Serra,   Teresa; Gil,   Jose Maria.
Multivariate local linear regression and parametric error correction models are applied to assess price linkages and price transmission patterns between food and energy prices in Spain. Weekly biodiesel, sunflower and crude oil prices observed from November 2006 to October 2010 are used in the empirical analysis. Results suggest the existence of a long-run equilibrium relationship between the three prices studied. Biodiesel is the only variable that adjusts to deviations from this long-run parity. Local linear regression techniques show that the speed of adjustment of biodiesel prices is higher when biodiesel is cheap than when it is expensive. Energy prices are also found to influence sunflower oil prices through the short-run price dynamics.

Understanding Market potential for biodiesel in Spain: A Pilot study based on consumer preferences
Provedor de dados: 31
Autores: Gracia,   Azucena; Barreiro-Hurlé,   Jesús; Perez y Perez,   Luis.
The production and use of biodiesel is an important alternative in Europe to diminish the emission of gases in order to fulfill the Kyoto protocol goals. Supported by the Common Agricultural Policy (CAP), the production of biodiesel has increased in Europe but the consumption is only of considerable importance in some countries. In Spain, the consumption of biodiesel is still low compared to other EU countries. The aim of the paper is to analyze consumers’ preferences for biodiesel in Spain. To do that a choice experimental approach has been used to assess consumers’ valuation of different diesel options and calculate the willingness to pay for biodiesel. The data come from a recent survey conducted in Spain (Region of Aragón). Results indicate that diesel...

DOES INTENSITY OF CHANGE MATTER? FACTORS AFFECTING ADOPTION IN TWO AGRI-ENVIRONMENTAL SCHEMES
Provedor de dados: 31
Autores: Barreiro-Hurlé,   Jesús; Espinosa-Goded,   Maria; Dupraz,   Pierre.
Agri-environmental schemes are the main policy instrument currently available in the EU to promote environmentally friendly farming practices. Nevertheless, the adoption rate of these measures is still limited. This paper develops a theoretical framework to explain farmer sign-up decision and tests whether factors affecting this decision differ depending on the level of requirement of each measure. The model is tested with two different AES in Spain implying a low and a high farm management change. Technical factors are found to be most relevant when significant farm practice changes are at stake while the role of farmer characteristics is significant when minor changes are required. In both cases, social capital and farmer attitudes still explain part of...

Liming increases crop production through improved soil conditions in acidic soils. Among the effects of liming, increased availabilities of alkaline and alkaline-earth cations are worth mention. These availabilities may be affected by the particle size of applied limestone, which influences lime reactivity. The effects of particle size and application schedule of magnesium limestone were investigated on extractable Ca, Mg and K in soil, their concentrations in sward plants and dry-matter yield. Magnesium limestone of various particle sizes was applied to experimental plots at a rate of 3 t ha-1, a grass-clover sward was sown, and the plots were monitored during three years. The finest limestone (&lt; 0.25 mm) in a single application yielded the highest...

This paper describes the occurrence of toxic cyanobacteria along the Guadiana River over its course between Mérida and Badajoz (Extremadura, Spain). Water sampling for phytoplankton quantification and toxin analysis was carried out regularly between 1999 and 2001 in six different locations, including two shallow, slow-flowing river sites, two streamed river sites and two drinking water reservoirs. The cyanobacterial community differed significantly between these locations, especially during the summer. The predominant genera were Microcystis, Oscillatoria, Aphanizomenon and Anabaena. Using an ELISA assay the total microcystin contents of natural water samples from the most eutrophic locations ranged from 0.10 _ 21.86 mg mcyst-LR equivalent·L-1 in...
