Los grupos de interés y la presión medioambiental

[ES] Uno de los motivos de mayor peso que inducen a las organizaciones a la implantación de sistemas de gestión medioambiental es la presión ejercida por los grupos de interés. La investigación aporta resultados sobre cuál es la influencia de los grupos de interés sobre la gestión medioambiental. Con este fin hemos analizado 142 centros de negocio españoles, poseedores de los certificados ISO 14000 y/o EMAS, estableciendo la relación de los grupos de interés y su influencia con el modo en que se realiza en dichas organizaciones la gestión medioambiental.

Neues Institut für Fischereitechnik und Fischqualität. Zusammenlegung der Institute für Fischereitechnik und Biochemie und Technologie

Entsprechend dem Rahmenkonzept für die Bundesforschungsanstalten im Geschäftsbereich des damaligen Bundesministeriums für Ernährung, Landwirtschaft und Forsten vom 12. 6. 1996 ist an der Bundesforschungsanstalt für Fischerei in Hamburg die Anzahl der Institute von fünf auf vier zu reduzieren. Das ab 1. 1. 2001 neu gebildete Institut für Fischereitechnik und Fischqualität (IFF) nimmt die Forschungsaufgaben der beiden bisherigen Institute für Fischereitechnik (IFH) sowie Biochemie und Technologie (IBT) wahr. Damit bietet sich für das aus zweivergleichsweise kleinen Instituten hervorgegangene IFF die Möglichkeit, in einem integrierten Ansatz Fische, Krebse und Weichtiere auf verschiedenen Stufen der Produktions- und Verarbeitungskette zu untersuchen und zu bewerten. Fangprozess und Folgebehandlung der Fangobjekte werden dadurch ganzheitlich betrachtet, was sich nicht zuletzt in Maßnahmen zur Qualitätserhaltung und -verbesserung von Fischen und Fischereierzeugnissen niederschlagen soll.

Weitere Selektionsuntersuchungen an Schleppnetzsteerten für den Plattfischfang in der Ostsee

The presentation includes investigations and results regarding Baltic flatfish selectivity with different trawl codend constructions. These investigations were carried out 1999/ 2000 on board of FRV “Clupea” and a commercial 17 m cutter. As could be shown, both an enlarged mesh size and another mesh form than rhombic can improve the selectivity of these fish. As flatfish catches with trawls mostly also cover cod, this mixed fishery at the southern Baltic coast should in future be managed by differentiated technical regulations for an improved selectivity. The results, also based on UW observations, current measurements, and wind tunnel tests with models, demonstrate some possible technical solutions.

Gegenüberstellung von mathematisch-physikalischer Modellierung und Messungen an geschleppten fischereitechnischen Systemen

When drafting a new model of a towed technical system for fisheries (trawl, towed TV gear or similar), and also when measuring an existing and already tested system it is not easy to foresee of practical behaviour, which depends of various parameters. The measuring programme for recording all data needs a lot of time and money, and also has some limitations. Therefore we developed for such systems mathematical-physical models, which allow a complex calculation. Their real value, however, results only from practical verification. During the cruise no. 222 of “Walther Herwig III” in November 2000 comparative investigations for 2concrete systems were carried out. This was done in cooperation with the University in Rostock, where such models are being developed and computerized. One of the systems mesasured was a pelagic herring trawl and the other one the towed TV gear for underwater observations of the Institute for Fishery Technology and Fish Quality. The correspondence between model calculation and measurements was very high for both systems.

Ostseedorschselektion - bestehende und vorgesehene neue technische Maßnahmen

Since the beginning of the nineties the situation of the Baltic cod stock is deteriorating constantly. The fishery administration (International Baltic Sea Fisheries Commission) tries to counter this by issuing new technical measures. Existing measures (raise of mesh opening from 105 to 120 mm, “Danish” and “Swedish” escape windows) and newly introduced technical measures (BACOMA codend and raise of the mesh opening in conventional codends to 130 mm) show a number of deficiencies putting their efficiency in doubt. Available well tested alternatives to the newly introduced measures without their negative side effects (codends made of netting turned by 90°, and other designs) are presently left out of regard. Models of socioeconomic effects are likewise ignored.

Fischbestände der Ostsee, ihre Entwicklung seit 1970 und Schlussfolgerungen für ihre fischereiliche Nutzung - Teil 2: Hering

The herring of the Baltic Sea shows a complicated population structure. Comparable to herring in other areas it can also be discriminated as spring and autumn spawning herring. Autumn spawning herring has been nearly vanished since the late 1960’s. Baltic Sea spring spawning herring show a broad variety as far as morphometric and other biological characteristics are concerned. It seems not very likely that all those differences are genetically based. The spawning sites of populations are, however, often clearly separated and such groups of herring are in most cases characterized by distinct differences in individual growth. Therefore for assessment purposes it is necessary to distinguish between as small as possible units in order to not endanger smaller populations to become extinct by overexploitation. On the other hand migrations and mixing of herring of different origin especially during the summer feeding period result in extreme difficulties of the discrimination of small units. For this reason only three herring assess ment units have been identified for the central and the northern Baltic Sea: herring in Sub-divisions 25–32+32, herring in Sub-division 30 and herring in Sub-division31. The spring spawning herring of the western Baltic Sea has been combined with spring spawning herring in Division IIIa. Only the herring stock in Sub-division 30 shows a positive development in the past. The largest assessment unit in Sub-divisions 25–29+32 decreased continuously during the whole period 1974–1998. The western Baltic Spring spawning herring stock decreased from 1990 to 1996. There is an ongoing debate on scientific level whether the combination of small populations into large assessment units like the one in S-D’s 25–29&32 might include the danger of the extinction of small compartments of the unit. On the other hand the practice by the International Baltic Sea Fishery Commission of managing the Baltic Sea herring fisheries by dividing a yearly Total Allowable Catch for the whole area among fishery zones without taking care of any biological structure and any individual stock development is totally against the idea of sustainability of fisheries.

Why are we fat? Discussions on the socioeconomic dimensions and responses to obesity

This paper draws together contributions to a scientific table discussion on obesity at the European Science Open Forum 2008 which took place in Barcelona, Spain. Socioeconomic dimensions of global obesity, including those factors promoting it, those surrounding the social perceptions of obesity and those related to integral public health solutions, are discussed. It argues that although scientific accounts of obesity point to large-scale changes in dietary and physical environments, media representations of obesity, which context public policy, pre-eminently follow individualistic models of explanation. While the debate at the forum brought together a diversity of views, all the contributors agreed that this was a global issue requiring an equally global response. Furthermore, an integrated ecological model of obesity proposes that to be effective, policy will need to address not only human health but also planetary health, and that therefore, public health and environmental policies coincide.
