| This paper introduces the field of mixture toxicity and the challenges in regulating pesticide mixtures. Even though pesticides are unique chemical stressors designed to have biological activity that can affect a number of nontarget species, they are intentionally placed into the environment in large quantities. Currently, methods and terminology for evaluating mixture toxicity are poorly established. The most common approach used is the assumption of additive concentration, with the concentrations adjusted for potency to a reference toxicant. Using this approach, the joint action of pesticides that have similar chemical structures and modes of toxic action can be predicted. However, this approach and other modeling techniques often provide little insight... |

| This paper explains the development and implementation of a methodology for assessing the economic impacts of large-scale environmental regulations. The development process began with a literature review surveying channels through which environmental regulations might influence economic performance. Avenues deemed suitable were incorporated into a computable general equilibrium (CGE) model of the California economy. This model is based on the California Department of Finance's Dynamic Revenue Analysis Model (DRAM). Modifications to DRAM for the current project include a revised sectoring scheme that features industries of particular regulatory interest, revamped data matrices that accommodate this new sectoring scheme, a new air pollution module,... |

| Port activities require continuous or occasional dredging of considerable quantities of sediments : approximately 50 million m3 along the French coastline. A large proportion of the dredgings is authorized for dumping at sea in geographically delimited areas and following an impact evaluation of their potential harmfulness to the marine environment. The environmental risks assessment linked to dredging operations relies on knowledge related to several scientific disciplines contributing to changes in the regulations. This work, intended both for managers and for environmental scientists and engineers, is designed to take stock of the current state-of-the-art in the field of sediment contamination and related ecotoxicological hazards, along with a review of... |

| The wine value chain is characterized by its traditional nature. The transformation of the raw material makes lasting products with a high added value, which entails large price differences between producers and consumers. Given the socioeconomic important of this sector, it has specially been taken into account by the administration, with a high level of intervention. There is an ample range of interventions, from a qualitative and from a quantitative point of view. The main objective of all these policies is the intention of controlling the supply and stimulating the demand. The impact of these measures is considered in the short term, to solve the surplus problems. However, at the long run, it has a negative impact. The new framework of the wine... |

| The Ifremer Repamo network (REseau de PAthologie des MOllusques) is the national surveillance network in charge of monitoring marine mollusc health on French coastlines. It is commissioned to enforce the official regulations and to provide a public service, under the supervision of the competent authority (DGAL Veterinary Directorate) in the Ministry.of Agriculture and Fisheries. Its goals are to prevent the introduction and the dissemination of infectious agents, in particular pathogens involved in reportable diseases, and to monitor the changes in the pathogens already present on the French coasts. |

| The Bolivia study is part of an ongoing multiple case study organized by the FAO's Regional Office for Latin America and the Caribbean as part of the activities of the Technical Cooperation Network on Agricultural Biotechnology (REDBIO/FAO). The basic information was obtained through a survey and/or direct interview to a significant number of experts from Bolivian institutions involving management, regulation, research, innovation, application and education of agricultural biotechnology. At national level, the most relevant applied agri-biotechnologies are presently in vitro plant culture, genomics, molecular genetics, assisted reproduction techniques in animals, and techniques supporting plant and animal disease diagnosis. They have been developed and... |

| Rent dissipation in open access fisheries is a well studied problem (Gordon 1954; Homans and Wilen 1997). Regulation is seen as a possibly remedy to the externality of entry, which eventually leads to zero profits and depressed stocks. Despite regulation, drastic declines have occurred in many regulated fisheries worldwide, prompting a discussion of economic, biological, and environmental phenomena that may lead to declines. We explore one case when a regulator permits overfishing in the context of a traditional fishery model. Influenced by industry to reduce effort restrictions, regulators often rely on gear, season length, and other efficiency restrictions to achieve management goals. Under standard assumptions we find that when the regulator is... |
