According to international law, straddling fish stocks should preferably be managed cooperatively through regional fisheries management organizations (RFMOs). This paper analyzes the stability and success of these organizations through a game in partition function form based on the classical...

In this paper, a discrete time, multi-gear and age structured bio-economic model is developed for the Northern Atlantic Bluefin Tuna, which is a paradigmatic example of the difficulties faced in managing highly migratory fish stocks. The 1995 U.N. Fish Stocks Agreement provides guidance as to...

Large-scale use of nitrogen-based chemical fertilizers, specific to intensive agriculture, has undesirable effects consisting of soil degradation and atmospheric loading with carbon dioxide. Good practice illustrates, however, that sustainable agriculture can be achieved by substituting as much...

Many fish consumers reveal a preference for sustainably sourced seafood in their purchasing decisions. We propose a bioeconomic modeling approach and an empirical strategy, based on a discrete choice experiment, to quantify the resulting effects on fishery dynamics and to derive implications for...

Following the advice of the 2014 evaluation of the Thünen Institute by the German Science and Humanities Council, the Thünen Institute has started to encourage its working groups to be evaluated by external experts as part of its quality management. The Marine Recreational Fisheries Working...

The role of economic analysis in guiding the sustainable development of estuarine and coastal ecosystems is investigated based on a comprehensive review of the literature on the valuation of the recreation, cultural and aesthetic services. The implications of the findings for the sustainable...

Plattfische wie Scholle (Pleuronectes platessa), Flunder (Platichthys flesus) und Kliesche (Limanda limanda) zählen zu den wichtigsten Zielfischarten der Angelfischerei in der Nord- und Ostsee. In der Ostsee werden jährlich erhebliche Mengen Plattfische durch die Angelfischerei gefangen, wobei...

Community-based reverse osmosis (RO) water treatment plants provide an interim solution for producing safe drinking water for the endemic areas of chronic kidney disease of unknown etiology (CKDu) in the rural dry zone of Sri Lanka. RO-treated groundwater diminishes the progression of CKDu;...

An issue that affects the effectiveness of water pricing policies is consumers misperception, which implies that households decide their water consumption based on poor/inaccurate information about the marginal price. We use household survey data on bill and quality perception in Brazil to...
