Data about marine area-based management tools to assess their contribution to the UN sustainable development goals.

The dataset presented in this article contains information about marine Area-Based Management Tools (ABMTs) used to assess their contribution to the United Nations 2030 Sustainable Development Goals. Following the scope of the analysis, ABMTs were identified by scrutinizing international and regional legal sources related to ocean management in the fields of marine conservation, fisheries, deep sea bed mining, underwater natural and cultural heritage, environmental conservation, and marine spatial planning. Legal sources were screened to depict the following characteristics of individual ABMTs: i) management objectives; ii) authorities responsible for delivering such objectives; iii) the system of management and planning entailed in the ABMT including the zoning type; and iv) the specific spatial scope and domain each ABMT refer to in vertical depth and horizontal domain. Data were generated through an internal expert elicitation. Experts, initially trained in the data analysis and related protocol, contributed to the data production because of their specific knowledge and experience in ocean management. This dataset represents a unique source of information for advancing research about monitoring and assessment of the achievement of sustainable development goals that encompasses different types of ABMTs.

Mapping the future: Pressures and impacts in the Portuguese maritime spatial planning.

Maritime Spatial Planning (MSP) is bringing new challenges to planning and management in the marine realm, namely on the environmental assessment of the new plans and projects. Portugal is developing its first MSP instrument, PSOEM (Plano de Situação do Ordenamento do Espaço Marítimo), since 2015 and published it on December 2019. This paper focuses on a particular stage of the Strategic Environmental Assessment (SEA) of PSOEM regarding the assessment of the activities/uses that may significantly affect Natura 2000 marine network during the Plan's implementation in the Mainland subdivision. Over the years, progress has been made in researching and assessing the environmental impacts of maritime activities/uses. However, its application to practice raised several challenges and limitations. The methodological approach presented in this paper was developed to overcome knowledge, data and time constraints. Some of the limitations are a consequence of the MSP approach itself adopted in Portugal, namely the low technical detail on future uses and activities, which is required and desirable at this level of planning. Others relate with the lack of spatially explicit data on marine habitats and species distribution preserved under Natura 2000 network, which is not fully established in the marine environment. The adopted methodology started with the characterization and mapping of the conservation values and the pressures arising from the potential activities/uses. It followed with the assessment of their impacts and finally with the identification of mitigation measures, which were then adopted by the PSOEM as good practices. As new knowledge is generated and more information is collected, this tailor-made approach can be easily adapted and improved to keep supporting decision-making throughout PSOEM's implementation. The method can be easily adapted and transferred to other contexts, not only within the Portuguese maritime area, and could be made available to stakeholders that wish to invest in blue growth.

Identifying conservation priority areas to inform maritime spatial planning: A new approach.

Accommodating sea uses while protecting the ecosystems is a challenge of the marine planning and management process. The European Directive on Maritime Spatial Planning calls for Maritime Spatial Plans until 2021 developed within an Ecosystem Based Management approach. The main goal of this study is to support the Maritime Spatial Planning process with ecological meaningful information, namely identifying priority areas for conservation that are facing less anthropogenic impacts. We developed a new approach for selection of high priority areas for conservation using Marxan software and Cumulative Impacts decision support tools. We identified four main areas prone to conservation in Portuguese mainland subdivision, namely the areas of Figueira da Foz/Peniche, south Cabo Espichel/Sines, Cabo Sardão/Faro and Lagos/Faro. The outputs from this study show the valuable input when allocating space to activities and uses in the marine realm supporting the planning process in the development of management alternatives. This case study also illustrates how ecological goals can be better included to contribute to the Maritime Planning process in Portugal. Systematic planning can be applied to support the connection between Marine Strategy Framework and Maritime Spatial Planning European Directives. This is highly relevant in the time being for Portugal, as the 2nd cycles of both directives are ongoing.
