In Auseinandersetzung mit natürlichen, geographischen und klimatischen Bedingungen haben sich im Verlauf langer historischer Prozesse typische und arbeitsteilig aufeinander bezogene Funktionen von maritimen Wirtschaftsstrukturen, Küstenregionen und Hafenstädten herausgebildet. Ein zentrales...

Water pollution in the Venice Lagoon and its catchment is a main environmental issue. In Italy public funds are made available by specific national and regional regulations in order to support the realisation of initiatives for the abatement of pollutant loads that travel from the catchment into...

The need for management of the marine ecosystem using a broad perspective has been recommended under a variety of names. This paper uses the term Ecosystem Management, which is seen as a convergence between the ecological idea of an organisational hierarchy and the idea of strategic planning...

Ecosystem Management requires models that can link the ecosystem level to the operation level. This link can be created by an ecosystem production model. Because the function of the individual fish in the marine ecosystem, seen in trophic context, is closely related to its size, the model groups...

The term 'Fishing Down Marine FoodWebs' describes the gradual transition in landing from marine ecosystems towards organisms lower in the food web. To address this issue and the need to manage the marine ecosystem in a broader perspective, Ecosystem Management is recommended. Ecosystem...

Angesichts stark wachsender Nachfrage nach Rohstoffen, insbesondere vonseiten der aufstrebenden Schwellenländer und entsprechend steigender Rohstoffpreise, richtet sich der Blick zunehmend auf die Tiefsee als enorme noch weitgehend unerschlossene Quelle reichhaltiger Rohstoffvorkommen. Der...

We analyse internal migration triggered by natural disasters in Bangladesh. We conducted a survey in nine coastal districts and two major cities in Bangladesh to investigate whether floods and cyclones, which can be considered as transient shocks, affect interregional migration differently...

Coastal areas are commonly defined as the interface or transition areas between land and sea, including large inland lakes. Coastal areas are diverse in function and form, dynamic and do not lend themselves well to definition by strict spatial boundaries. Unlike watersheds, there are no exact...
