Awareness of the environmental problems associated with conventional finfish aquaculture has stimulated interest in more sustainable production methods. For example, integrated multitrophic aquaculture (IMTA) combines the culturing of fish and extractive aquaculture species at one site to simulate a balanced natural system. In contrast, closed containment aquaculture (CCA) separates farming from the natural marine environment using closed water tanks on land or in water. We explore consumer preferences for salmon produced with IMTA or CCA rather than conventional technology and pose two questions: how aware of IMTA and CCA are salmon consumers on the U.S. West Coast and what are they willing to pay for salmon produced with these methods? Using a discrete choice experiment, we estimate marginal willingness-to-pay of 39.0% and 15.7% for IMTA and CCA, respectively, as a premium added to the price of conventionally farmed Atlantic salmon. Results using latent class analysis show that consumers with a strong preference for wild salmon have high marginal values for farmed salmon produced with IMTA or CCA, but the average consumer from this group would be unlikely to purchase it. Overall, 44.3% and 16.2% of the respondents preferred IMTA or CCA to conventional salmon farming, respectively, and IMTA was preferred to CCA when respondents were asked to choose one. La sensibilisation aux problèmes environnementaux liésà l'élevage de poissons classique suscite un intérêt pour des méthodes de production plus durables. Par exemple, l'aquaculture multitrophique intégrée (AMTI) combine l'élevage de poissons et d'espèces d'extraction sur un même site afin d'imiter unécosystème natureléquilibré. En revanche, l'aquaculture en parc clos (APC) consiste en unélevage hors du milieu marin naturelà l'aide de réservoirsétanches installés sur le sol ou dans l'eau. Dans la présenteétude, nous avons analysé les préférences des consommateurs pour le saumon issu de l'AMTI ou de l'APC et celui issu de l'élevage classique. Nous nous sommeségalement posé deux questions :A quel point les consommateurs de saumon de la côte Ouest desÉtats-Unis connaissent-ils l'AMTI et l'APC, et combien sont-ils prêtsà payer pour obtenir du saumon issu de ces méthodes de production? A l'aide de la méthode des choix discrets, nous avons obtenu un consentementà payer marginal de 39,0 % pour l'AMTI et de 15,7 % pour l'APC, de plus que le prix du saumon de l'Atlantique issu de 93 94 CANADIAN JOURNAL OF AGRICULTURAL ECONOMICS l'élevage classique.

Cultural landscapes in Austria are multifunctional through their simultaneous support of productive, habitat, regulatory, social, and economic functions. This study investigates, if changing climatic conditions in Austria will lead to landscape change. Based on the assumption that farmers are the crucial decision makers when it comes to the implementation of agricultural climate change policies, this study analyzes farmers’ decision-making under the consideration of potential future climate change scenarios and risk, varying economic conditions, and different policy regimes through a discrete choice experiment. Results show that if a warming climate will offer new opportunities to increase income, either through expansion of cash crop cultivation or new land use options such as short-term rotation forestry, these opportunities will almost always be seized. Even if high environmental premiums were offered to maintain current cultural landscapes, only 43 % of farmers would prefer the existing grassland cultivation. Therefore, the continuity of characteristic Austrian landscape patterns seems unlikely. In conclusion, despite governmental regulations of and incentives for agriculture, climate change will have significant effects on traditional landscapes. Any opportunities for crop intensification will be embraced, which will ultimately impact ecosystem services, tourism opportunities, and biodiversity.
Loss of natural heritage is a problem that is particularly prevalent in areas of high population density. We used a survey to understand the factors that drive environmental behavior of landowners in southwestern Ontario, Canada. The survey, which contained questions about environmental attitude, pro-environmental behavior and demographics, was mailed to 18,090 rural route addresses, and we received 3256 completed surveys (18% response rate). Two types of environmental behavior, namely voluntarily increasing the area of land set aside for conservation, and enrollment in a conservation stewardship program, were significantly correlated with a positive attitude towards conservation. Financial considerations also played a role. We showed that the biggest motivator to enroll in a wetland enhancement program was access to 'more information on how the decline in wetland area affects them personally', while 'public recognition' was the least motivating factor. We suggest that enrollment in voluntary land stewardship programs might be increased by providing information about the effects of ecosystem loss, and by providing financial incentives for participation. In a larger social context, outreach programs by government agencies could focus on improving pro-environmental attitudes, which in turn is likely to result in more pro-environmental behavior of landowners.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
