First steps towards a quota allocation system in the Indian Ocean

In response to recommendations made by a recent performance review, the Indian Ocean Tuna Commission (IOTC) is attempting to develop a quota allocation system (QAS) for management of the tuna and tuna-like species of the Indian Ocean. As “first-movers” in the process, Indonesia, the Seychelles, the European Union, Iran, and the Republic of Korea made contrasting proposals to the IOTC in March 2011 on possible QAS form and structure. Structure (the factors to be taken into account in determining allocation) is critical as it will determine on a long term basis the share accruing to each IOTC member state of the estimated USD 2-3 billion worth of tuna caught in the Indian Ocean each year. This article records and discusses the content of these first steps towards QAS formulation by placing them in the context of rights-based management as applied to the offshore areas falling under tuna RFMO management. The options proposed in March (which the IOTC is still considering) all have a similar architecture but result in sharply divergent allocation outcomes. Despite the sophistication of some of the proposals, the recent IOTC review suggests that the regulatory and management capacity of the IOTC does not match the science and enforcement requirements appropriate to these recent proposals. Perhaps efforts to improve IOTC performance need to be made in parallel with discussions on QAS definition and implementation. To further advance the debate and also concretely demonstrate likely economic outcomes, the article provides indicative monetary valuations of quota allocations proposed. It uses a range of potential historical reference periods (5, 10, 15, and 20 years).     

The targets of management rules for marine mammal populations require justification: A reply to

The management of anthropogenic impacts on marine mammal populations involves the setting of targets that are built on assumptions and choices. Scientific methods can be used to investigate the implications of management actions, but the choice of overall objectives and priorities lies outside science. A recent paper (Potential biological removal and other currently used management rules for marine mammal populations: A comparison in Marine Policy), summarised the characteristics of the main approaches currently used to set conservation management targets for marine mammal populations in order to provide a basis for discussion of the targets they contain. Cooke et al. (Management rules for marine mammal populations: A response to Lonergan in Marine Policy) responded, giving some important additional information about these management rules. However most of that paper's criticisms were incorrect or misplaced. Specifically, it erroneously treated an example of how PBR could be reworked, to make its abundance explicit, as a proposal to ignore uncertainty in managing populations. This paper addresses Cooke's main criticisms, and suggests that explicit justifications should be an important part of the process of setting targets for the management of marine mammal populations.     

Measuring the benefits and costs of community education and outreach in marine protected areas

Conservation organizations often invest considerable resources in education and outreach activities in and around marine protected areas (MPAs). The expectation is that such efforts will change local knowledge, attitudes and ultimately behavior. This is one of the first studies to assess the efficacy of using education and outreach activities to improve community knowledge and attitudes about an MPA. Random sample surveys in 2005 and 2010 (n=1213) before and after education and outreach activities are compared. Program budgets for the same period give the investment levels. With an investment level averaging US$24 per capita/year, the result was an average increase of 33% in “yes” responses across 15 indicators of knowledge and attitudes towards marine conservation. The increase in knowledge and positive attitudes was associated with a large decrease in “not sure” responses, suggesting that community members with fewer initial preconceptions are the most effective target for education and outreach activities. This study demonstrates that investments in MPA education and outreach can generate increases in local knowledge and positive attitudes, and changing knowledge and attitudes is expected to contribute to the long-term compliance with MPA regulations.     

Australia’s no-take marine protected areas: Appropriate conservation or inappropriate management of fishing?

The absence of properly identified mechanisms to adequately protect the marine environment remains a major shortcoming in Australia’s commitment to biodiversity conservation. The current commitment to a National Representative System of Marine Protected Areas (NRSMPA) falls far short of providing adequate protection against the suite of existing and potential threats even though areas are designated as being ‘protected’. In this paper it is argued that the actions taken under the NRSMPA are disproportionately concentrated on regulating fishing, including the closing of areas in so-called sanctuary zones to all types of fishing. In the absence of clearly identified threats from most forms of fishing and without assessment of how best to manage those few fishing threats that have been identified, such actions are inefficient and mostly inappropriate. Moreover, they do not provide adequate protection against the full suite of threats to marine environments. Adequate measures for the proper conservation of these areas and/or the protection of marine biodiversity more generally are not being provided and in most cases threats are not even adequately described and evaluated.     

The Common Fisheries Policy: An enforcement problem

Marine populations in Europe are in decline due to the unsuccessful results of the Common Fisheries Policy. By combining data of scientific recommendations from ICES, TACs approved and reported landings with an age-structured model, the objectives of this paper are to investigate the level of compliance of the TAC regulation, and the level of enforcement and its economic impact on fishery resources. The results presented here suggest that while there does not exist a regular pattern between TAC proposal and TAC approved, there is a clear pattern between TAC approved and reported landings. As a consequence, there is a regular lack of enforcement at national fisheries authority level. The paper also presents results of the recovery plans for the Southern hake and the Atlantic cod fisheries as case studies to illustrate the level of enforcement based on collusion between national fisheries advisers and industry. The results from both cases studies analyzed here indicate that drastic solutions could generate positive results for the recovery of the stocks, but perhaps they are not always the best measure in fisheries management due to the high economic losses for fishermen and social effects on coastal communities in the short and medium term. Finally, this work demonstrates that if the recovery plans had been implemented, the net present profits for both fisheries would have increased over time.     

Improving marine environmental health through marine citizenship: A call for debate

This paper presents an evaluation of the role of marine citizenship in improving marine environmental health and marine governance. Marine citizenship describes the rights and responsibilities of an individual towards the marine environment, which support the achievement of marine policy objectives at the national level. It is argued that marine citizenship requires an enhanced awareness of marine environmental issues, an understanding of the role of personal behaviour in creating and resolving marine environmental issues, and a shift in values to promote marine pro-environmental behavioural choices. It is concluded that the value shift is likely to be produced by the development of an altered relationship between the state and the individual, in which the expectations placed on citizens by the state are extended to include marine pro-environmental behaviour. The paper is intended to stimulate debate and the authors invite and encourage replies to the ideas contained within the paper.     

Shifting accountabilities? Understanding the connections between national and provincial fisheries in Papua New Guinea

This paper examines the effects of fisheries decentralization strategies in Papua New Guinea. The paper assess the financial, human resources, information, and institutional mechanisms that the National Fisheries Authority uses to connect with provincial fisheries offices to show the consequences of institutional reforms. The findings suggest both intended and unintended effects, particularly in terms of shifting accountabilities and loyalty. These findings are broadly applicable to decentralization and institutional change scholars and practitioners interested in understanding how governments implement institutional change reforms and the effects of this implementation.
