The EU Water Framework Directive (WFD) calls for cost-effective measures to achieve a good status in all European ground, surface and coastal waters. Besides eutrophication, the degradation of hydro-morphology is the main reason for failing the WFD's objectives in Germany. In this paper , we...

One of the major scientific challenges posed by the EU Water Framework Directive (WFD) is the de-sign of a decision support process that meets the directive's requirement to achieve good status using a cost-effective combination of measures. This paper presents BASINFORM, a new decision tool for...

Governance has definitely become a very iridescent concept in recent years. The term is widely used, meanwhile, in almost all social-science disciplines as well as in the political process. The intention of this paper is not so much to clarify these sometimes vague meanings but to highlight some...

We analyze a dynamic and stochastic ecological-economic model of grazing management in semi-arid rangelands. The non-equilibrium ecosystem is driven by stochastic precipitation. A risk averse farmer chooses a grazing management strategy under uncertainty such as to maximize expected utility from...

Im vorliegenden Aufsatz wird ein Begriffskonzept entwickelt, das zum besseren Verständnis des Zusammenspiels der Dynamiken von Ökosystemen und Wirtschaft dient: das Konzept des Bestandes. Der Bestandsbegriff wird allgemein mengentheoretisch formuliert. Die zentrale Eigenschaft eines Bestandes...

A region of ecological importance which generates uncompensated cross-territorial positive spillovers has a comparatively higher fiscal need due to the direct and indirect costs it incurs for nature conservation. In order adequately to acknowledge fiscal needs relating to nature conservation, we...

Biodiversity loss is a serious global environmental problem. Economic instruments in biodiversity policies can contribute towards reconciling the conservation costs encountered at local level with the benefits of biodiversity conservation at higher levels of governance, from regional and...

The fishpond landscapes in Central and Eastern Europe have immense historical and cultural value, and are highly significant as a habitat for numerous endangered species. Typical examples of cultural landscapes, their maintenance depends on (extensive) fishpond farming. However, although the...
