4. Use and maintenance of Ocean Accounts

Table of Contents



  • This section provides guidance relevant to the ongoing maintenance of Ocean Accounts (including the generation of time series), and the use of Ocean Accounts to inform ocean governance. Particular attention is devoted to producing indicators, data sources, policy and governance use cases, research use cases, and enabling factors such as institutional, regulatory, and legal frameworks.


4.1 Indicators for sustainable development

  • This section presents a general discussion of the importance of indicators for sustainable development policy, linking to the Summary Indicators table of Section 3.8.

4.1.1 SDG Indicators

  • To keep track of progress against the 17 Sustainable Development Goals and 169 associated targets, the Interagency and Expert Group on SDG Indicators (IAEG-SDGs) developed a framework of over 200 indicators, which was adopted by the UN General Assembly in July 2017. Countries are leading on the delivery of the SDGs, on a voluntary basis, and are encouraged to use the framework of globally agreed indicators to report on progress. This will require a significant level of capacity and resources from countries: many indicators do not currently have internationally established methodologies nor available data and/or associated monitoring schemes in place. Countries are encouraged to prioritise and develop their various monitoring schemes over time, in accordance with their national capacities.

  • To facilitate the implementation of the global indicator framework, the indicators have been classified into three tiers based on the global availability of methodologies and data (see Table 29 for tier classifications). Tier classifications are reviewed annually based on changes in methodologies and data availability and progress in the development of the indicators (as documented in associated work plans).


Table 29. Tier classification criteria and definitions for SDG indicators.

Tiers

Tier classification criteria / definitions

Tiers

Tier classification criteria / definitions

Tier 1

Indicator is conceptually clear, has an internationally established methodology and standards are available, and data are regularly produced by countries for at least 50 per cent of countries and of the population in every region where the indicator is relevant.

Tier 2

Indicator is conceptually clear, has an internationally established methodology and standards are available, but data are not regularly produced by countries.

Tier 3

No internationally established methodology or standards are yet available for the indicator, but methodology/standards are being (or will be) developed or tested. (As of the 51st session of the UN Statistical Commission, the global indicator framework does not contain any Tier III indicators)


  • Currently, there are few consistent approaches for data collection and reporting for global targets such as the SDGs, or the Aichi Targets of the UN Strategic Plan for Biodiversity (2010-2020). While social and economic data might be collected by National Statistics Offices in the countries, environmental and ecological data are often collected by Non-Governmental Organisations and research institutes at country, regional or even global levels. To support the global reporting process for SDGs, the Inter-Agency and Expert Group on SDG Indicators (IAEG-SDGs) is developing guidelines on data and information flows from national to global levels.

  • According to the IAEG-SDGs reporting guidelines, the monitoring data underlying the indicators will be collected and processed at the national level by relevant public and private-sector institutions, and brought together in reporting platforms by the National Statistics Office of the country. From here, the data and information will be transmitted to international agencies, either directly or through regional mechanisms such as the Regional Seas Programmes. The international agencies will then aggregate the country-level data at regional and global levels and submit these aggregates, along with the country data, into the Global SDG Indicators Database, which is maintained by the UN Statistics Division (UNSD). Appendix 6.5 provides an initial link between the SDG indicators and the Ocean Accounts Framework.

  • UNEP has developed a provisional Global Manual on Ocean Statistics which focuses on supporting countries in their efforts to track progress against the delivery of SDG14 and the specific indicators under UN Environment custodianship:

    • 14.1.1 Index of Coastal Eutrophication (ICEP) and floating plastic debris density.

    • 14.2.1 Proportion of national exclusive economic zones managed using ecosystem-based approaches.

    • 14.5.1 Coverage of protected areas in relation to marine areas.

4.1.2 Other indicator frameworks

  • The Framework for the Development of Environment Statistics (FDES) is a multi-purpose and statistical framework that conceptually defines the scope of environment statistics compatible with other frameworks such as the SEEA and the Driving force-Pressure-State-Impact-Response (DPSIR). It contains six components, 21 sub-components, 60 statistical topics and 458 basic statistics intended as a guide to the collection compilation of environment statistics particularly at the national level. The basic statistics also are organized into three tiers based on the level of relevance, availability and methodological development as follows:

    • Tier I or so-called core set of environment statistics (100 statistics) – high priority and relevance to most countries and have a sound methodological foundation.

    • Tier II (200 statistics) – relevance to most countries but require greater investment of time, resources or methodological development.

    • Tier III (158 statistics) – lower priority or require significant methodological development.

    • The FDES was endorsed by the 44th session of the Statistical Commission in 2013.

  • Ocean Health Index (OHI) measures the state of the world’s oceans in ten categories or “goals”, namely food provision, artisanal fishing opportunities, natural products, carbon storage, coastal protection, tourism and recreation, coastal livelihoods and economies, sense of place, clean waters, and biodiversity. In each goal, four dimensions of status, trend, pressures, and resilience are assessed using globally available, mutually non-exclusive sets of indicators. The OHI is presented in 236 regions including 221 coastal countries/territories and the Antarctic for which the assessment covers inland to one kilometre from the shore and seaward to either three or 200 nautical miles (Exclusive Economic Zone, EEZ), and 15 High Seas areas. The global score is an area-weighted average of the scores of all regions.

  • The Global Ocean Observing System (GOOS) is a coordination system of global ocean observations – situ networks, satellite systems, governments, UN agencies and individual scientists – on climate, operational services, and marine ecosystem health. It establishes “Essential Ocean Variables” (EOV’s) as a framework to coordinate efforts, avoid duplication, and set common standards for data collection and dissemination among different ocean observing networks and systems. There are 31 EOV’s and more than 100 sub-variables as of April 2020.

4.1.3 Disaster risk indicators

  • The Sendai Framework for Disaster Risk Reduction 2015-2030, the successor to the     Framework for Action (HFA) 2005-2015, was adopted at the World Conference on Disaster Risk Reduction held in Sendai, Japan and endorsed by the United Nations General Assembly in 2015. The framework sets out seven measurable targets to monitor progress towards its goal and expected outcome of reducing existing and preventing new disaster risks. The seven targets include:

    • Substantially reduce global disaster mortality by 2030, aiming to lower average per 100,000 global mortality between 2020-2030 compared to 2005-2015;

    • Substantially reduce the number of affected people globally by 2030, aiming to lower the average global figure per 100,000 between 2020-2030 compared to 2005-2015;

    • Reduce direct disaster economic loss in relation to global gross domestic product (GDP) by 2030

    • Substantially reduce disaster damage to critical infrastructure and disruption of basic services, among them health and educational facilities, including through developing their resilience by 2030;

    • Substantially increase the number of countries with national and local disaster risk reduction strategies by 2020;

    • Substantially enhance international cooperation to developing countries through adequate and sustainable support to complement their national actions for implementation of this framework by 2030; and,

    • Substantially increase the availability of and access to multi-hazard early warning systems and disaster risk information and assessments to people by 2030.

  • An internationally agreed set of 38 indicators were specifically developed to track progress of the seven global targets. The Sendai framework also contributes to measuring relevant targets and indicators of SDG 1, 11 and 13. The United Nations Office for Disaster Risk Reduction (UNDRR) is mandated to provide support to the implementation, follow-up, and review of the Sendai Framework. Disaster-related statistic framework (DRSF) complements the Sendai framework and SDG indicators by providing measurement and implementation guidance including definitions, classifications, concepts, and methodologies to integrate and harmonize statistics for disaster risk reduction. It proposes a basic range of disaster related statistics covering key statistics before, during and after an emergency event. ESCAP provides secretariat support to the development of the DRSF.

4.1.4 Climate change indicators

  • The UNECE CES Task Force on core climate change-related indicators and statistics has updated a set of related key climate change-related statistics using the SEEA and other statistical frameworks for implementation in the European region. The refined set of core climate change-related indicators contains 44 indicators – compared to an initial set of 39 core climate-change related indicators and statistics endorsed by the CES in 2017 – covering five climate change areas namely Drivers (9 indicators), Emissions (9 indicators), Impacts (13 indicators), Mitigation (8 indicators) and Adaptation (5 indicators). It also proposes the inclusion of operational indicators, contextual indicators, and the core climate change-related statistics.

  • Out of the 44 indicators, 8 are SDG indicators; 4 are conceptually identical to the Sendai framework; and 25 can be produced from the SEEA-CF and SEEA-EEA. At the global level, UNSD has initiated the development of a global set of climate change statistics and indicators since 2016. The global set will contain a list of climate change statistics/indicators consistent with exiting relevant indicator frameworks, including the UNECE CES set of core climate change-related indicators, and covering five IPCC areas: drivers, impacts, vulnerability, mitigation and adaptation. An initial set has been drafted and piloted by selected countries and international/regional organizations. The global consultation is being planned to be undertaken in mid-2020.

4.2 Data sources and platforms for Ocean Accounts

  • This section provides a more comprehensive treatment of data sources, building on the more specific guidance provided in Chapter 3. As advised in Chapter 3, there is a broad range of national data that can be exploited to compile ocean accounts, including:

    • existing statistical data such as the SNA, Census and social surveys, ongoing SEEA-CF and SEEA-EEA accounts such as solid waste, land, ecosystem condition, water, energy, environmental activities, ongoing compilations such as environmental compendia using FDES,

    • existing geospatial data, such as national land cover maps,

    • existing administrative data, such as fish catch or mine production statistics.

  • These existing data can be repurposed for use in ocean accounts. However, existing data may not be sufficient to compile the accounts that have been designated as priorities. In these cases, compilers may need to explore alternative sources, such as global geospatial and monitoring data. As well, they may need to apply estimation methods, including modelling, to fill gaps or build scenarios of future conditions.

  • This section provides insights into ongoing efforts to inventory, integrate and make available data on the ocean including:

4.2.1 The case for digital ecosystem for the environment

  • In the discussion paper “The Case for a Digital Ecosystem for the Environment” (Jensen & Campbell, 2019), UN Environment makes a compelling case on how data, technology and innovation can transform the way environmental data are collected and managed, and thus can critically enable conditions for better governance.

  • As reported by the UN Secretary General’s Independent Expert Advisory Group on a Data Revolution for Sustainable Development, without high quality geospatial data, the task of designing, monitoring, and evaluating effective policies to achieve the Sustainable Development Goals (SDGs) is almost impossible. The same concept can be applied to Ocean Accounting, whereby new data management technologies, artificial intelligence, cloud computing and cloud storage of information, together with increased volume of accessible geospatial data, are making it possible to manage, share, process and analyse large volumes of data in near real time as well democratizing access to the data itself.

  • The digital ecosystem proposed by UN Environment would comprise of the following four main components: (1) data; (2) infrastructure; (3) algorithms and analytics; and (4) insights and applications. Following this, an Ocean Accounting platform would transform data using an underlying infrastructure combined with algorithms and analytics (i.e. models) into insights and applications that are used by National Statistics Offices and other stakeholders.

  • Data: the volume of data currently being generated is so high that we are now accustomed to referring to it as “Big Data”. This term refers to large volumes of data that cannot be processed effectively with traditional applications. Big Data availability is however non-homogenous, as there are a wide variety of different sources (e.g. Earth observation remote sensing and in-situ platforms, citizen science, administrative and financial data, etc.) types (covering different spatial and temporal resolutions), quality, and formats.

  • Infrastructure: In order to manage this large volume of data a distributed infrastructure is needed which not only guarantees access (cataloguing, discovery, aggregation, navigation) and storage/archiving, but also maximises data sharing, integration and analysis. This can be achieved through cloud-based infrastructures which promote the principles of open accessibility and share standards for data sharing.

  • Algorithms and analytics: Data analytics can be defined as the processing of analysing data to provide meaningful insights and information. The process of extraction of relevant information can be automated into processes and algorithms that work over raw data for human consumption. The automated techniques for aggregating large volumes of data, detecting patterns, identifying trends and determining relationships include the adoption of Artificial Intelligence and Machine Learning algorithms.

  • Insights and applications: Data needs to be combined, processed and analysed to be transformed into information and ultimately actionable knowledge. End users and stakeholders must be able to understand and apply the information which is provided to them. This implies that information must be applicable, trustworthy, easy to access and simple to comprehend. In order to guarantee this, it is imperative that there is a common thread linking data producers, data managers, infrastructure experts, algorithm developers, application providers to end users and stakeholders.

  • In parallel to the concepts elicited by UN Environment for a digital ecosystem, a set of concise and measurable principles have been designed to guide and improve the Findability, Accessibility, Interoperability, and Reusability of digital assets. The FAIR guiding principles for scientific data management and stewardship (Wilkinson et al., 2016) can be considered as a conduit leading to knowledge discovery and innovation, and to subsequent data and knowledge integration and reuse by the community after the data publication process.

  • Building on these principles, the Secretariat on Group on Earth Observations (GEO) and the GEO Blue Planet initiative, are working on developing an ocean “Knowledge Hub”, an open platform aimed at empowering global experts where co-design, co-production & full reproducibility are key.

  • This is particularly relevant for countries and their National Statistics Offices engaged in Ocean Accounting (and monitoring of the Sustainable Development Goals indicators) as it will provide a platform where they can independently access data, algorithms, methodologies to produce the necessary information and actionable knowledge.

4.2.2 Earth observation data

  • Earth observations can be defined as the union of diverse data sources, including from satellite, airborne, in-situ platforms, and citizen observatories, which when integrated together, provide a robust basis for understanding the past and present conditions of Earth systems, as well as the interplay between them.[1] It is therefore the gathering of Earth’s physical, chemical, and biological information from a range of different sources required for improved monitoring and forecasting.

  • Earth Observation data can make a substantial contribution in supporting progress towards many of the Sustainable Development Goals (SDG), including those that are more socio‐economic in nature (Andries, et al., 2018). In addition, there is also potential to develop indicators outside the established set of SDG indicators that may be more amenable to the use of EO‐derived data, including Ocean Accounting.

  • The use of international (global) space-based earth observations, combined with in-situ and modelling datasets, is key for achieving a solid and reproducible Ocean Accounting framework. This is even more evident as we must consider the transboundary nature of ocean related targets and indicators, specifically for the monitoring and reporting of sea areas which are beyond national (agreed or not) national jurisdiction (i.e. EEZ waters). It is imperative to have a framework, combining space-based Earth Observations together with modelling and in-situ datasets, providing global, regional, and national geospatial ocean products.

  • The notion of national data is limited when applied to the ocean and there are a number of “global vs national” issues to be clarified, such as: (1) Who is responsible for the reporting and monitoring in areas beyond national jurisdiction (recognised EEZ's)?; (2) Who should contribute on providing an observational and measurement methodology for indicators which ensures the highest level of consistency and comparability, and; (3) What is the framework for developing transboundary ocean related SDG indicator products at global, regional, national and transboundary level?

  • In this context, ocean remote sensing data is invaluable as it provides a consistent, synoptic perspective that can be leveraged in a cost-effective manner by end-users in developing as well as developed nations. Satellite sensors provide insight on physical, biological, biogeochemical, geological, and social related ocean parameters at different spatial resolutions and temporal scales (hourly/daily to multi-annual). They provide rapid, repeated and long-term synoptic observations that inform and complement (in conjunction with in situ measures and modelling/data assimilation activities) a nested global to basin-scale to regional to local ocean observing framework. This represents the end-to-end value chain for ocean observations, going from observations → data → products → information → knowledge for users and the attendant socio-economic benefits.

  • Data collected at national level are of critical relevance for global and regional assessments. They feed analyses and modelling of regional seas while providing a validation instrument for regional and global datasets. It is important within this context to highlight that there is currently no clear framework defining: a) who should (can) contribute on providing an integrated observational and measurement methodology; b) how global and regional products can feed into national monitoring and reporting processes, and; c) who should routinely analyse, monitor and report on this indicator at global and regional level.

  • Cooperation, at global to local scales and across different sectors, is crucial to achieve long-term sustainable use of our ocean resources. Regional Seas Programmes, Agreements and Conventions can be key to the sustainability of regional coastal and marine ecosystems as they provide a governance and technical/ scientific mechanism for regional cooperation and coordination, aimed at advancing national and transboundary issues.

  • What is the relationship between global, regional and national products and how can we ensure that the data required for Ocean Accounting purposes is freely available, consistent, comparable and spatially comprehensive? At the regional level, we could envisage a set of "packages" of products that identify (or approximate) physical or ecological base values or critical thresholds (if known), with a well-defined pathway for their delivery. These regional “actors” can thereafter work with Member States to improve the uptake of Earth Observation data (and related derived products) to be used for monitoring and reporting at national level.

  • Ensuring the sustainable development and responsible conservation of our oceans requires working across national jurisdictions and open sea areas. Global Earth Observation data are fundamental resources that provide physical, biological, chemical, geological and social information on the ocean at different spatial resolutions and temporal scales.

  • All data collected, created and curated by Earth observation entities, organisations and programmes is of critical importance. The following three are particularly noteworthy as they cater for the majority of the ocean satellite remote sensing, in-situ and modelling observational datasets and resources:

  • Committee on Earth Observation Satellites (CEOS): made up of 55 space agencies from all around the world, exists to ensure the international coordination of satellite Earth observation programs and promotes data exchange to make satellite data available and beneficial to the world. These satellite observations are critical for ocean, coastal and land environmental monitoring, meteorology, disaster response, agriculture and other applications. CEOS organizations currently operate 112 satellites. These satellites and their related systems operate simultaneously and serve both interdisciplinary and international activities; therefore, international discussion and cooperation are critical to their success.

  • Global Ocean Observing System (GOOS): A sustained collaborative system of ocean observations, encompassing in situ networks, UN agencies and individual scientists organized around a series of components undertaking requirements assessment, observing implementation and innovation. 

  • OceanView: Fostering the development and improvement of operational ocean analysis and forecasting systems worldwide, OceanView defines, monitors and promotes actions aimed at coordinating and integrating research associated with multi-scale and multi-disciplinary ocean analysis and forecasting systems.

  • The close cooperation and collaboration with these entities and programmes is key when it comes to the definition of the Earth observation data requirements and needs for Ocean Accounting. Within this context, an initiative like GEO Blue Planet can provide the link between data producers, data managers, infrastructure experts, algorithm developers, application providers and ultimately end users/stakeholders.

4.2.3 “Essential” Ocean and Ecosystem Variables

  • One of the recommendations of the OceanObs’09 conference was for international integration and coordination of interdisciplinary ocean observations under a unique and common framework. The Framework on Ocean Observing (FOO, 2012) was implemented under the auspices of the Intergovernmental Oceanographic Commission (IOC) of UNESCO and is coordinated by the Global Ocean Observing System (GOOS). It seeks to meet the need of delivering ocean data to support governance, management, science and other ocean uses. It proposes the coordination and integration of routine and sustained observations of physical, biogeochemical, geological and biological essential ocean variables, or EOVs (Table 30). The EOVs are closely linked to the Essential Climate Variables (ECVs) (Bojinski et al., 2014) which define the observations needed to understand and track the status and trends in climate variability.

  • In parallel, the Group on Earth Observations Biodiversity Observation Network (GEO BON) has developed a framework for a set of Essential Biodiversity Variables (EBVs) (Table 31) for use in monitoring programs to understand patterns and changes in Earth's biodiversity (Pereira et al., 2013; Navarro et al., 2018). Within GEO BON, the Marine Biodiversity Observation Network (MBON) frames the EBVs concept for the marine realm (Muller-Karger et al., 2018).

  • The ecosystem Essential Ocean Variables (eEOVs) include a set of observable ecological quantities which contribute to the assessment of the ocean ecosystem (Miloslavich et al., 2018). When assessing the condition of the marine ecosystem for the Southern Ocean Observing System, A.J. Constable et al. (2016) identified nine general ecosystem properties to be monitored. These belong to three main areas as follows: (1) Spatial arrangements of taxa: habitat, diversity, spatial distribution of organisms; (2) Food-web structure and function: primary production, ecosystem structure, production, energy transfer, and; (3) Human pressures: regional and global.

  • Constable et al., (2016) used nine criteria for assessing the utility and feasibility of the candidate EOVs based on the following concepts: (1) Signal change in ecosystem properties; (2) Contribution to developing and/or applying models investigating change and attribution; (3) Understanding for policy-makers and the public; (4) Alignment with other eEOVs; (5) Ability to be connected to historical datasets ( time-series); (6) Potential to be adapted through time; (7) Can be sampled at space and time scales appropriate to the task; (8) Sufficiently high signal-to-noise ratio, and; (9) Potential for adaptive sampling.

  • These multidisciplinary and transdisciplinary efforts categorize specific ocean parameters to be monitored on a continuous basis for addressing the challenge of evaluating the status of our oceans, identify key processes and ultimately determine the sustainability of the ecosystem as a whole, in a synergistic way. Muller-Karger et al. (2018) analyses these efforts and provides a synoptic view for linking the GOOS led effort on EOV and eEOV to the GEO BON EBV proposal. These concepts and criteria are also relevant when evaluating the typology of data sources needed for ocean accounting and evaluating the availability of data at regional and global level. Below are two tables outlining the parameters currently included as EOVs and EBVs.
