European Integration,Urban Economic Change,and Public Policy Responses

Most empirical work on changing disparities in income during recently increased European integration examines the European Union (EU)‐defined regions because of a dearth of readily available urban units of analysis and economic indicators. Moreover, a lack of systematic data on urban entrepreneurial efforts fuels debate over their effectiveness in enhancing urban prosperity. I combine a quantitative analysis of trends in income disparities for the Western European urban system for 1980‐1994, with comparative case studies using qualitative and quantitative information for three problem cities in Britain that were selected in order to investigate the types and effectiveness of their urban entrepreneurial efforts. On the one hand, the macro analysis provides no clear evidence of convergence in urban incomes. On the other hand, while the public‐private partnerships in the problem cities vary somewhat depending on local context, their entrepreneurial strategies are remarkably similar. Higher levels of economic development spending, however, do not translate necessarily into improved urban performance.     

Early Carboniferous blueschist facies metamorphism in metapelites of the West Sudetes (Northern Saxothuringian Domain,Bohemian Massif)

The metamorphic evolution of micaschists in the north‐eastern part of the Saxothuringian Domain in the Central European Variscides is characterized by the early high‐pressure M1 assemblage with chloritoid in cores of large garnet porphyroblasts and a Grt–Chl–Phe–Qtz ± Pg M2 assemblage in the matrix. Minerals of the M1–M2 stage were overprinted by the low‐pressure M3 assemblage Ab–Chl–Ms–Qtz ± Ep. Samples with the best‐preserved M1–M2 mineralogy mostly appear in domains dominated by the earlier D1 deformation phase and are only weakly affected by subsequent D2 overprint. Thermodynamic modelling suggests that mineral assemblages record peak‐pressure conditions of ≥18–19 kbar at 460–520 °C (M1) followed by isothermal decompression 10.5–13.5 kbar (M2) and final decompression to <8.5 kbar and <480 °C (M3). The calculated peak P–T conditions indicate a high‐pressure/low‐temperature apparent thermal gradient of ～7–7.5 °C km^?1. Laser ablation inductively coupled plasma mass spectrometry isotopic dating and electron microprobe chemical dating of monazite from the M1–M2 mineral assemblages give ages of 330 ± 10 and 328 ± 6 Ma, respectively, which are interpreted as the timing of a peak pressure to early decompression stage. The observed metamorphic record and timing of metamorphism in the studied metapelites show striking similarities with the evolution of the central and south‐western parts of the Saxothuringian Domain and suggest a common tectonic evolution along the entire eastern flank of the Saxothuringian Domain during the Devonian–Carboniferous periods.     

EU–Mauritania fisheries partnership in need of more transparency

The new protocol signed in July 2012 by the European Union and Mauritania under the existing Fisheries Partnership Agreement did not produce the expected results. The main component of this protocol consisted of the access rights for 300,000 t/yr of small pelagics. During the first five months after the signature of the protocol, no EU pelagic trawlers used the opportunities created by the protocol. Only after the formal approval of the protocol by the European Council in December 2013, some eastern EU member states started sending their pelagic trawlers back to Mauritania. This resulted in a utilisation of the protocol of 54% for the whole of 2013. Although the EU repeatedly stated that the €70 million/yr paid under the protocol provided good value for money, this assertion was hard to maintain considering the limited utilisation of the agreement. The paper analyses why the EU concluded an agreement with Mauritania that was not wanted by their industry and that was therefore only partially used in the end. It describes the decision making process inside the EU; the different parties involved and their different objectives. It is concluded that the EU decision making process suffers from a lack of transparency and that the combination of a business agreement with development aid resulted in an agreement which did not attain either of the stated objectives. It is proposed that in future the two aspects are clearly separated, and that the development component is extended to other countries in West Africa, including those that have no fish to sell to the EU.     

Yield estimation using SPOT-VEGETATION products: A case study of wheat in European countries

In the period 1999–2009 ten-day SPOT-VEGETATION products of the Normalized Difference Vegetation Index (NDVI) and Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) at 1 km spatial resolution were used in order to estimate and forecast the wheat yield over Europe. The products were used together with official wheat yield statistics to fine-tune a statistical model for each NUTS2 region, based on the Partial Least Squares Regression (PLSR) method. This method has been chosen to construct the model in the presence of many correlated predictor variables (10-day values of remote sensing indicators) and a limited number of wheat yield observations. The model was run in two different modalities: the “monitoring mode”, which allows for an overall yield assessment at the end of the growing season, and the “forecasting mode”, which provides early and timely yield estimates when the growing season is on-going. Performances of yield estimation at the regional and national level were evaluated using a cross-validation technique against yield statistics and the estimations were compared with those of a reference crop growth model. Models based on either NDVI or FAPAR normalized indicators achieved similar results with a minimal advantage of the model based on the FAPAR product. Best modelling results were obtained for the countries in Central Europe (Poland, North-Eastern Germany) and also Great Britain. By contrast, poor model performances characterize countries as follows: Sweden, Finland, Ireland, Portugal, Romania and Hungary. Country level yield estimates using the PLSR model in the monitoring mode, and those of a reference crop growth model that do not make use of remote sensing information showed comparable accuracies. The largest estimation errors were observed in Portugal, Spain and Finland for both approaches. This convergence may indicate poor reliability of the official yield statistics in these countries.     

Regime shifts in the marine environment: the scientific basis and political context

Regime shifts in the marine environment have recently received much attention. To date, however, few large-scale meta-analyses have been carried out due to insufficient data coverage and integration between sustained observational datasets because of diverse methodologies used in data collection, recording and archival. Here we review the available data on regime shifts globally, followed by a review of current and planned policies with relevance to regime shifts.We then focus on the North and Baltic Seas, providing examples of existing efforts for data integration in the MarBEF Network of Excellence. Existing gaps in data coverage are identified, and the added value from meta-analyses of multiple datasets demonstrated using examples from the MarBEF integrated data project LargeNet. We discuss whether these efforts are addressing current policy needs and close with recommendations for future integrated data networks to increase our ability to understand, identify and predict recent and future regime shifts.     

Trophic importance of diatoms in an intertidal Zostera noltii seagrass bed: Evidence from stable isotope and fatty acid analyses

A current predominant paradigm emphasizes the role of epiphytic algae for invertebrates in most seagrass food webs. However, in some intertidal Zostera noltii beds, epiphyte biomass is very low compared to microphytobenthos and seagrass biomasses. We assessed the role of microphytobenthos in a temperate intertidal Z. noltii bed by combining stable isotope and fatty acid (FA) analyses on primary producers, composite sources — suspended particulate organic matter (SPOM) and sediment surface organic matter (SSOM) — and the main macrofaunal consumers. Z. noltii showed high δ¹³C (−9.9‰) and high 18:2(n-6) and 18:3(n-3) contents. Microphytobenthos was slightly more ¹³C-depleted (−15.4‰) and had high levels of diatom markers: 14:0, 16:1(n-7)c, 20:5(n-3). Low mean δ¹³C (−22.0‰) and large amounts of diatom and bacteria (18:1(n-7)c) markers indicated that SPOM was mainly composed of a mixture of fresh and decayed pelagic diatoms. Higher mean δ¹³C (−17.9‰) and high amounts of diatom FAs were found in SSOM, showing that microphytobenthic diatoms dominate. Very low percentages of 18:2(n-6) and 18:3(n-3) in consumers indicated a low contribution of Z. noltii material to their diets. Grazers, deposit and suspension-deposit feeders had δ¹³C close to microphytobenthos and high levels of diatom FAs, confirming that microphytobenthos represented the main part of their diet. Lower δ¹³C and higher amounts of flagellate FAs – 22:6(n-3) and 16:4(n-3) – in suspension feeders indicated that their diet resulted from a mixture of SPOM and microphytobenthos. These results demonstrate that invertebrates do not consume high amounts of seagrass and highlight the main role of benthic diatoms in this intertidal seagrass bed.     

Solving complex fisheries management problems: What the EU can learn from the Nordic experiences of reduction of discards

A crucial issue for the new EU common fisheries policy is how to solve the discard problem. Through a study of the institutional set up and the arrangements for solving the discard problem in Denmark, the Faroe Islands, Iceland and Norway, the article identifies the discard problem as related to both natural, other material and to cultural conditions. Hence, solving the discard problem requires not only technical and regulatory instruments, but also arenas and structures that allow and facilitate processes of cultural change.     

Progress in Integrated Coastal Zone Management (ICZM) in Northern Ireland

The history of development of Integrated Coastal Zone Management (ICZM) in Northern Ireland is described here in the context of European and UK initiatives. The current structures for ICZM in Northern Ireland involve a formal strategy. This involves a number of specific actions in the environmental, social, and economic spheres with specific goals pertaining to integration. The strategy has been agreed by all responsible organisations (both governmental and NGOs), and each action is time-bound and has an identified responsible agency. The Northern Ireland Coastal and Marine Forum (NICMF) which consists of non-governmental members, has the task of monitoring the implementation of the strategy and acting as a catalyst for integration. The strengths of the current structure lie in the presence of an integrating ICZM strategy and the fact that the initiative is government-led in response to the EU Recommendation on ICZM. These provide better levels of sustainability and links to the statutory system of governance compared to the partnership model in Great Britain. Its main weaknesses are: (i) that the NICMF relies on voluntary participation; (ii) linkages between government departments have not been substantially improved; and (iii) weak mechanisms for ensuring goals are achieved.
