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 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...

As four of every five European citizens live in urban areas, their quality of life and the quality of their environment depends upon how cities look and how they function. Cities are also places where business is done, investments are made and jobs are created....

The recent literature on unified growth theory has shed new light on the transition to sustained economic growth. Nevertheless, unified growth theory has not devoted a lot of attention to the nature of economic growth and its impact in the transition from Malthus to Solow. This research presents...
