Ecosystems & the Ocean: Implementing Ocean Accounts for Sustainable Development

This overview discusses the importance of integrating ocean accounts into national planning and development processes to achieve sustainable development goals. It explores the unique characteristics of the ocean and how the System of Environmental-Economic Accounting (SEEA) can help in understanding and valuing ocean ecosystems. It also highlights country examples and challenges in implementing ocean accounts.

  3. From the video… Ecosystems & Oceans

  4. Knowns: The ocean is essential. Known unknowns: How essential? Unknown unknowns: What if? Ocean Science 101 Land & Freshwater Biophysical Ecosystems +Oxygen -CO2 Socio-economic Consumption Accumulation Atmosphere Climate Weather +Natural inputs +Services -Residuals -Modification +Water The ocean Biophysical Ecosystems -Heat -Acidification -CO2 +Oxygen Impacts: Climate change Sea-level rise Natural disasters Ecological collapse Ecosystems & the Ocean

  6. SNA + SEEA + ? = Ocean Accounts SNA = System of National Accounts SEEA = System of Environmental-Economic Accounting ESCAP Ocean Accounts Partnership

  7. System of environmental-economic accounting (SEEA) Environment Economy Production Consumption Accumulation Imports Exports P = Price (monetary value) Q = Quantity (physical) Ecosystems & the Ocean

  8. SEEA-Ecosystems (spatially detailed) Thematic:Land, Water, Carbon, Biodiversity Tools: Classifications, Spatial units, scaling & aggregation, Biophysical modelling Extent Condition Physical Services Supply Services Use Tools: Valuation techniques Services Supply Services Use Monetary Asset Augmented I-O Table Supporting:SNA, I-O tables, economic production functions Integrated Sector Accounts and Balance Sheets Ecosystems & the Ocean

  9. Many SEEA accounts  many related SDGs + poverty [1] + equality [5, 10] + economy [8] + disaster [11] + SCP [12] By 2020, integrate ecosystems and biodiversity values into national and local planning, development processes and poverty reduction strategies, and accounts… How are we doing so far? SEEA: Central Framework + Ecosystems Ecosystems & the Ocean

  10. Global Ocean Observation System (GOOS)What & how to measure  Sea surface temperature  Sea surface salinity http://www.goosocean.org/index.php?option=com_content&view=article&id=120&Itemid=277 Ecosystems & Oceans

  11. SDG 14 interactions with other Goals Progress on other Goals may have negative impacton SDG14 • SDG 1: + Poverty reduction;- conservation limits access • SDG 2: + Food security; - conservation limits access • SDG 7: + renewable energy– Energy for All  increase GHGs  acidification • SDG 8: + Growth of marine and maritime economy;- impacts on ocean ecosystems • SDG 11: + urban development;- impacts on ocean ecosystems • SDG 12: + efficient use of natural resources • SDG 13: + Blue carbon sink;- adaptation to climate change may conflict with conservation Source: Griggs et al. 2017 Ecosystems & Oceans

  12. SEEA Ecosystems: Early work Source: Remme et al., 2014 (Limburg, the Netherlands) Source: Statistics Canada, 2013 Ecosystems & the Ocean

  13. The Ocean A Different kind of “ecosystem” • It’s very large • Water & species keep moving • Multi-layer • All looks the same from a satellite • Trans-boundary / shared / most outside of national jurisdictions • Less studied / known / measured • Interacts with climate, disaster, food… • Not tested with SEEA • ESCAP YouTube Video; UN Environment: Ocean Pollution Ecosystems & the Ocean

  14. Ocean accounts – Map view National Spatial Data Infrastructure (NSDI) SEEA Ecosystem extent - Land Accounts: Terrestrial and Freshwater ecosystem types - Catchment areas - Coastal communities - Coastal infrastructure - Pollution sources Ocean spatial units - Ocean ecosystem types - Marine protected areas - Fishery, tourism, mining areas - Water quality / temperature National statistics - Emissions, effluents, wastes - Assets: fish stock - Supply/use: catch, beneficiaries Governance - Mandates Analyses - Main sources of land-based pollution (by whom) - Degraded and pristine “Hot spots” - Cost/benefit of rehabilitation and protection - Value of natural inputs (to whom) - Policy options  values at risk - Capture of “rent” (returns on investment) ESCAP Ocean Accounts Partnership

  15. Ocean accounts – Table view Ecosystems & the Ocean

  16. Regional expert workshop (Aug. 2018) Remaining research issues… • Spatial units & ecosystem classification: Delineate units • Ecosystem services: Expand existing classifications • Disaster risk & climate change: Establish shared standards • Social: Identify communities, artisanal fishers, target groups • Economic: Standard definitions & valuation of non-SNA • Global data: What is available and how to use it • Measuring SDG14: Metadata & new indicators • Ocean governance: International, regional and national • Modelling: Experience and opportunities • Priorities for pilot studies and research Ecosystems & the Ocean

  17. 1. Spatial units & ecosystem classification • Many global spatial frameworks (mostly partial) • EMU: Ecosystem Marine Units • LME: Large Marine Ecosystems • MEOW: Marine Ecoregions of the World (WWF) – coastal/shelf • Global data not coherent • New Global Shoreline (30m) • National data coherent? • National spatial data infrastructure (NSDI) includes marine? • CMECS (Coastal and Marine Ecological Classification Standard) from US • Not tested globally (Australia has adapted for benthic) • Conditions: Which measures? Ecosystems & the Ocean

  18. EMU: Ecosystem Marine Units (USGS/ESRI) Based on 27km, historical temperature, salinity, nutrients • From NOAA World Ocean Atlas • At many depths (three-dimensional complex shapes) • Map shows description of “column” • Not detailed for coastal • ESCAP testing correlations with • Aragonite • Coral 16,520 Polygons 1,749 Combinations Adapted from: Sayer et al. 2017. Ecosystems & the Ocean

  19. Global shoreline vector (GSV) at 30m Why important? • Standardized globally • All mainlands, large islands, small islands • Annual 2014 composite • Needed for Ecosystem Coastal Units • Corrects historical maps Red = GSV  Yellow = Global Selfconsistent, Hierarchical, High-resolution Shoreline (GSHHS) (1996)  Underlying = ESRI World Image Basemap (not vector) Sayer et al. 2018 Ecosystems & the Ocean

  20. Large Marine Ecosystems (LMEs) LMEs are vast regions of coastal ocean space of 200,000 km2 or more, extending from river basins and estuaries seaward to the continental shelf break or slope or to the outward margins of major current systems. Unique defining ecological criteria of LMEs include bottom depth contours, currents and water mass structure, marine productivity, and food webs. (http://onesharedocean.org) Ecosystems & Oceans
