Dette er en hovedfagsoppgave. ; In this thesis I have taken a broad view on international environmental co-operation; What are the incentives, obstacles and ways to enhance participation and compliance with international environmental agreements. I have also looked at a more specific issue; The implementation of the "flexible mechanisms" of the Kyoto Protocol, and particularly joint implementation projects between an investor in a developed country and a host in an economy in transition or developing country.

This is an Accepted Manuscript of an article published by Taylor & Francis in Aquaculture Economics & Management on 22 July 2019, available online: https://www.tandfonline.com/doi/full/10.1080/13657305.2019.1641570 . ; According to governmental plans, Norway faces huge expansions in the production of farmed Atlantic salmon. However, it is municipalities that designate coastal areas to aquaculture activities and their motivation depends on net benefits at municipal level from such use. Yet, there is little empirical evidence on costs and benefits of using coastal areas to aquaculture activities. We set up a cost-benefit analysis of salmon farming as seen from a municipal perspective. On the benefit side, we count consumer and producer surplus of increased aquaculture production in the region and the region's share of the national rent in aquaculture received as transfers from the national Aquaculture Fund. Costs are the opportunity cost of the land (sea) use, measured by households' willingness to pay to avoid aquaculture expansion, using data from a choice experiment. We find that parts of the producer surplus have to contribute to the regional economy for the NPV to be positive for a region.

Failure of the blue revolution is a global risk. The international problem is that there is a gap in knowledge exchange between the aquaculture industry, policymakers trying to support aquaculture development and people who depend on aquaculture for a job and/or food source. Thus, governments and international organizations promoting aquaculture as the solution to improving food security, nutrition and income are failing to optimise production of natural aquatic resources. We identify a "people–policy gap", and suggest that this is an understudied constraint, which needs to be overcome before worldwide food security can be achieved from aquatic environments. We argue that this gap leads to uneven distribution of benefits, a disconnection between benefits and local needs, and detrimental effects on human health and food security, all of which can have negative repercussions on human communities and ecosystems. In order to address this need, we present an analytical framework to guide context specific, policy-relevant assessments of the social, economic and ecological dimensions of aquaculture on a case-by-case basis. The framework is designed to make best use of existing data and scientific tools for decision-making. In conclusion, we argue for: equal consideration of ecological, social and economic issues in aquaculture policymaking; pre-emptive identification of likely social impacts; integration of people- and context-specific social framing conditions into planning and policy review; addressing the social disconnection between global consumption and production; and, encouragement of creative combinations of theories and methods to assess and interpret the social dimensions of aquaculture in multiple contexts.

This paper focuses on the availability of economic indicators and metrics to assess effects of marine aquaculture production in the North Atlantic area (the EU, Norway, Canada and USA), including also social and environmental effects. We consider how aquaculture planning and management is organised in the different countries and the usefulness of economic information to address different aquaculture‐related policies. We find that the most relevant economic data for aquaculture management should be at the local and regional levels rather than nationally. The availability of such economic data is mapped for national, regional and local level. The focus is on data that are publicly available from authorities or research institutions. The availability of data is generally fairly good for national and regional data on the direct economic effects of aquaculture. Data on how aquaculture‐related products or input markets are affected are however poorly available, as are economic data on external effects from aquaculture. Countries with a larger aquaculture sector tend to have better availability of aquaculture‐related economic data than those with a smaller sector. An index is developed and calculated to show more specifically where the countries have relatively good or poor data availability compared to their needs. While it will not always be cost‐effective or meaningful to collect economic data on the effects of aquaculture, our study indicates that several countries could benefit from expanding such data collection. It can make trade‐off decisions more consistent and easier to perform, and aquaculture policies and measures can be better tailored to specific contexts.
