We analyze the management of a coastal aquifer under seawater intrusion using distributed control methods. The aquifer's state is taken as the water head elevation, which varies with time and in space since extraction, natural recharge and lateral water flows vary with time and in space. The...

We develop a bioeconomic model of the northern Balticsalmon fishery that takes into account thesimultaneous harvest of wild and reared salmon. Weassess the optimal harvest allocation between thecommercial offshore, inshore, and estuary fisheries,and the recreational river fishery that...

The paper analyses the social optimal management of terrestrial animal species where land-use costs, non-consumptive benefits of the wild species and nuisance costs, in addition to harvesting profit, are taken into account. When there is harvesting, it is demonstrated that increased...
