This paper describes the application of the participatory diagnosis and adaptive management (PDAM) framework to analyze the governance of small-scale fisheries and the potential for adopting the Ecosystem Approach to Fisheries (EAF) in Misamis Occidental, Philippines. Using the Rapid Appraisal...

The multispecies fisheries management looks at a bigger picture in addressing the long-term consequences of present decisions. This implies an ecosystem management that includes a number of species and their physical, biological and economic interactions. These interactions make the growth of...

The Laboratory of Forestry economics (LEF) was created in 2000 as a joint research unit of the French Institute of Forestry, Agricultural and Environmental Engineering (ENGREF) and the National Institute of Agronomic research (INRA). The mission of the LEF is to conceive, develop, and transfer...

Fisheries managers in the United States are required to identify and mitigate the adverse impacts of fishing activity on essential fish habitat (EFH). There are additional concerns that the viability of noncommercial species, animals that are habitat dependent and/or are themselves constituents...

This study examines the spatial nature of optimal bioinvasion control. We develop a spatially explicit two-dimensional model of species spread that allows for differential control across space and time, and we solve for optimal spatial-dynamic control strategies. We find that the optimal...

This paper models the use of community sanctions to restrict effort in a simple Gordon-Shaefer style model of the fishery with heterogeneous fishing costs.

Resumen El establecimiento de Áreas Marinas Protegidas se ha definido como la principal herramienta para la protección y conservación de los ecosistemas marinos y costeros. Dentro de los beneficios que ofrece el establecimiento de estas áreas se encuentran aumentos en la biodiversidad de...

Nutrient enrichment of marine ecosystems is regarded as a pressing global environmental problem. For certain marine species it may be a mixed blessing, resulting in damaging ecosystem events, but contributing to primary productivity. Consequently, the impact of enrichment on fishery profits may...

Catastrophic risk is currently a hotly debated topic. This paper contributes to this debate by showing two results. First it shown that the value function in dynamic optimization can have an infinite derivative at some point even if the model specification has functional forms that are finite...

This paper identifies the optimal options of Krabi's coastal land use to facilitate the final planning decision. Through compromise programming approach, the optimization models with respect to the weights assigned to two objectives of maximizing the net private and environmental benefits are...
