The viewpoints of 30 Cape Verdean fishermen are used together with an analysis of the state of tuna stocks in the Atlantic Ocean to question the EU's claim that their fleet only targets surplus species. Additionally, local marine catches of the artisanal and semi-industrial fleet are evaluated...

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...

The purpose of this paper is to examine the stability of the cooperative management agreement of the North Atlantic Bluefin tuna fisheries over time,as the stock recovers, assuming that the players were engaged in previous cooperation for a certain period of time. This analysis is focused on the...

Метод динамического программирования (МДП) Беллмана исключительно эффективен для решения широкого класса задач экономико-математического моделирования. В...

Outcomes of the shallow lake interest conflict are presented in a number of different contexts: quasi-static and dynamic social planning, and quasi-static one-shot and repeated non-cooperative play. As the underlying dynamics are non-convex, the analysis uses geometrical-numerical methods: the...

We analyze how the threat of a potential future regime shift affects optimal management. We use a simple general growth model to analyze four cases that involve combinations of stock collapse versus changes in system dynamics, and exogenous versus endogenous probabilities of regime shift. Prior...

This paper presents an evolutionary based approach to achieve optimal management of a coastal aquifer to control saltwater intrusion. An improved Elitist Continuous Ant Colony Optimization (ECACO) algorithm is employed for optimal control variables setting of coastal aquifer management problem....

Method of dynamic programming (MDP) of Bellman is exceptionally efficient for solving a wide class of tasks of economic and mathematical modelling. In a number of cases MDP has no alternative. Meanwhile, statements of specialists with respect to correctness of justification of MDP and also with...

We study the economic impact of the viral disease AVG, its stochastic transmission across abalone reefs in southern Australia, and the optimal management response as AVG approaches an uninfected reef. Using conservative estimates of the virulence and mortality rates associated with the disease,...
