TL;DR: This study presents the main outcomes of a broad project implemented by the General Fisheries Commission for the Mediterranean (GFCM) of the Food and Agriculture Organization of the United Nations (FAO) called “Indicators for the sustainable development of aquaculture and guidelines for their use in the Mediterranean” (2008-2015), with emphasis on the relevance of the process that led to the selection and identification of a pool of indicators.
Abstract: Aquaculture sustainability builds upon its environmental, economic, sociological and governance dimensions and although the recent global interest in aquaculture sustainability has arisen due to the rapid expansion of the sector, lack of consensus and diverging conflicts among stakeholders have often compromised and lessen the achievement of real actions to ensure the sustainable development of aquaculture. The use of indicators in aquaculture is considered one of the most appropriate tools to monitor and assess the growth of sustainable aquaculture activities. In this study, we present the main outcomes of a broad project implemented by the General Fisheries Commission for the Mediterranean (GFCM) of the Food and Agriculture Organization of the United Nations (FAO) called “Indicators for the sustainable development of aquaculture and guidelines for their use in the Mediterranean” (2008-2015), with emphasis on the relevance of the process that – in the areas of several Mediterranean riparian countries – has led to the selection and identification of a pool of indicators for monitoring the sustainable aquaculture development from an initial regional reference system of 156 indicators. The development of case studies at the local level based on PCI approach (Principles-Criteria- Indicators) has allowed among other things to identify the main steps that were necessary to build local consensus on the selection, implementation and performance assessment of aquaculture indicators, with the involvement of key stakeholders. In the case studies, the 156 selected indicators and related criteria were ranked by the local stakeholders based on their perception and understanding the local priorities at the time of the case studies to achieve the sustainable development of aquaculture in each area. Based on the importance of the criteria by the stakeholders, we studied the order of relevance assigned to the indicators for one of each of the four pillar of aquaculture sustainability (governance, social, economic and environmental). Several direct and indirect positive effects deriving from the implementation of aquaculture indicators are presented. Furthermore, the work carried out highlighted also that the identification and use of indicators and criteria applied is an evolving process reflecting the dynamic status of aquaculture development and the perception of its sustainability at the time in which the indicators are identified. The work was carried out consistently with the participatory approach principles and focusing on the criteria associated to the social acceptability of aquaculture considered an integral part of sustainability.

TL;DR: For effective governance to support processes that apply principles of sustainable development and an ecosystem approach to decide about economic activities at sea such as aquaculture, there is an urgent need to rethink how best to reconcile nature conservation and sustainable development.
Abstract: To meet the Convention on Biological Diversity's Aichi Target 11 on marine biodiversity protection and Aichi Target 6 on sustainable fisheries by 2020, as well as the Sustainable Development Goal (SDG) 2 on food security and SDG 14 on oceans by 2030, there is an urgent need to rethink how best to reconcile nature conservation and sustainable development. This paper argues for effective governance to support processes that apply principles of sustainable development and an ecosystem approach to decide about economic activities at sea such as aquaculture. It describes opportunities, benefits and synergies between aquaculture and MPAs as a basis for wider debate. The scope is not a comprehensive analysis of aquaculture and MPAs, but rather to present examples of positive interactions between aquaculture activities and MPAs. The unintended negative consequences are also discussed to present balanced arguments. This work draws from four workshops held in 2015 and 2016 and used to collect information from about 100 experts representing various sectors and perspectives. It is recognized that aquaculture is an important activity in terms of sustainable development. It can play a role in providing food security, poverty alleviation and economic resilience, in particular for MPA local communities, and contribute to wild stock enhancement, as an alternative to overfishing and for providing services to the ecosystem. This study showed that there is a need from both aquaculture and MPA sides for clarity of objectives and willingness for open and extensive dialogue. The paper concludes by describing a number of tools and methods for supporting greater synergies between aquaculture and MPAs. The results from this work have already helped to build a common understanding between conservation and aquaculture and initiate a rapprochement for increasing synergies.

Abstract: The search for healthier protein sources and the growing demand for food by an increasing world population require aquaculture systems to not only be economically and technologically viable, but also sustainable. Among other methods, emergy synthesis is a powerful tool to assess the sustainability of production systems in a biophysical perspective. However, applications of emergy synthesis on aquaculture systems are seldomly found in the scientific literature. This work provides a literature review on emergy synthesis applied to aquaculture systems and discusses its constraints and potentials. The sixteen papers published between 2000-2020 support the adoption of polycultures more than monocultures and highlight the importance of feed (4–70%) in the total emergy required by aquaculture systems, which require efforts for natural food. Methodological aspects of emergy synthesis applied in aquaculture systems that deserve attention by developers and analysts to avoid mistakes and erroneous conclusions were identified and discussed, and we propose some ways to solve them. These aspects are mainly related to inaccurate unit emergy values for water and feed, dubious procedures in quantifying and classifying water as renewable or non-renewable resources, and the need to recognize the importance in accounting for ecosystem services and disservices. After overcoming these methodological inconsistencies, we foresee that emergy synthesis has potential political implications in supporting most sustainable aquaculture systems through economic (tax reduction and loans with reduced interests) and political (green labels) incentives. All these policies are important to achieve the ultimate goals of the United Nations’ Agenda 2030.
