Artisanal fishery in the Venice lagoon is a multi-target activity with a long tradition. It was the main fishing activity till the late '80s when, after the introduction and spread of the Manila clam (Tapes philippinarum), the mechanical clam harvesting started. A mass-balance model of the...

This paper reviews a number of OECD data sources to examine their potential for establishing indicators which can contribute to monitoring progress towards two of the 2011-2020 Aichi Biodiversity Targets under the Convention on Biological Diversity (CBD), namely Target 3 on Incentives and Target...

Artisanal fishery in the Venice lagoon is a multi-target activity with a long tradition. It was the main fishing activity till the late '80s when, after the introduction and spread of the Manila clam (Tapes philippinarum), the mechanical clam harvesting started. A mass-balance model of the...

This paper analyzes the optimal management of a natural resource that can shift between different dynamics at random times. Using a classical linear control model I investigate how the switching behavior influences the optimal extraction of the resource. I use exogenous sea-surface temperature...

We combine and extend two existing lines of research in game theoretic studies of fisheries. The first line of research is the inclusion of the aspect of predation and the consideration of multi-species fisheries within classical game theoretic models of fisheries and goes back to Quirk and...

The conservation of biodiversity is a major environmental issue, one that promises to remain at or near the top of the environmental agenda for the foreseeable future. The loss of biodiversity affects human welfare as well as being lamentable for its own sake. Humans depend on natural systems to...

From ecosystems we derive food and fiber, fuel and pharmaceuticals. Ecosystems mediate local and regional climates, stabilize soils, purify water, and in general provide a nearly endless list of services essential to life as we know it. To understand how to manage these services it is essential...

Various complex dynamics in ecologic-economic systems are presented with an emphasis upon models of global warming dynamics and fishery dynamics. Chaotic and catastrophic dynamic patterns are shown to be possible, along with other complex dynamics arising from non-linearities in such combined...

Various complex dynamics in ecologic-economic systems are presented with an emphasis upon models of global warming and fishery dynamics. Chaotic and catastrophic dynamic patterns are shown to be possible, along with amplified oscillations due to these non-linear interactions in the combined...

The public trust doctrine is an ancient doctrine of public property law that governs sovereign stewardship of natural resources. The doctrine both promote public access to trust resources and requires sovereign protection of them for the benefit of the public, including future generations. The...
