Introduction

Natural Asset Register and Natural Capital Accounts research considers how we can systematically account for ecosystem services in Scotland.  We are developing a publicly accessible register of Scotland’s natural assets, to improve our knowledge of how much of what is where, and which assets are at risk in particular places. The web page for the current version of this register can be viewed by clicking here. Datasets will be added to the register as they become available during the five years of the research programme. Bundled ecosystem services within specific habitats in the register can then be valued and act as a foundation for natural capital accounting. These data will be used in the rest of Work Package 1.4 looking at sustainable management of natural assets.

Research will explore how the stocks and condition of natural capital assets can be better linked to ecosystem service flows through the use of remote sensing data and the development of modelling approaches. The research will also inform the refinement of SNH’s Natural Capital Asset Index and better targeting of agri-environment measures in Scotland.

Natural capital accounting research will focus on applying accounting approaches across a range of spatial scales to meet the needs of different end users. This will rely on existing data supplemented where necessary with new valuation studies. A case study approach is used, with initial accounts developed for agriculture and forestry sectors with urban greenspace currently in development. Approaches to measuring non-monetary values are also being explored with particular reference to cultural services.

Aim of Research

Natural Asset Inventory and Natural Capital Accounts: the aim is to develop a spatially-referenced register of Scotland’s natural assets and contribute to a set of natural capital accounts for Scotland that can over time track the progress of Scotland's green growth aspirations.

Progress

2018 / 2019
2018 / 2019

Progress has continued in developing the Natural Asset Register (NAR). This has included working with SEFARI colleagues and stakeholders in Scottish Government and agencies to develop the data portal. Expected outputs from Theme 1, the Natural Assets theme of the Strategic Research Programme, have been audited to identify future data for inclusion in the NAR.

There has been continued engagement with SNH to develop and improve the Natural Capital Asset Index (NCAI), including submission of a peer reviewed journal paper on the NCAI. Work has also continued to develop methods to assess ecosystem services flows from a range of data sources.

Work on agri-environment targeting demonstrated that results are sensitive to the analytic method used. One implication is that optimum method selection is dependent on whether the objective of schemes is to target a wide range of species or rare species. The results of this work have been published in Global Ecology and Conservation.

Natural capital accounts have been produced for the agriculture and forest sectors; these focused on the scaleability of available biophysical and valuation data across different spatial scales of interest to different users. Work to better account for the spatial aspects of natural capital valuation has also continued and will inform the next accounting case study which will focus on urban ecosystem services.

Highlights:

  • Natural Asset Register: the NAR data portal now has 29 datasets including outputs from the agri-environment and climate scheme targeting research. Further data have been added on water quality and quantity monitoring research undertaken in the Strategic Research Programme.
  • Natural Capital Asset Index: SNH has continued to develop the NCAI with inputs from the SRP. This is gaining traction as a key performance indicator for Scotland.
  •  Natural capital accounts: reports for the agriculture and forest sectors have demonstrated the variation in the ecosystem service benefits provided by these land used across Scotland. These variations reflect both the condition of the natural capital assets and the differences in benefiting populations.

The Natural Asset Register (NAR) is now publicly available as a Data Portal and its population with datasets is ongoing. Science to support the development and content of the NAR has progressed, including remote sensing and modelling of peat and the participatory mapping of cultural ecosystem services, and collaboration with SNH continues to improve the Natural Capital Asset Index and targeting of AECS payments. Analysis of the primary valuation data to inform farmland and forest natural capital accounts has continued and draft accounts for these sectors are planned to be available by Autumn 2018.

Highlights:

  • Targeting Agri-Environment Schemes for Biodiversity: Analysis of alternative methods of targeting agri-environment payments shows that the current method based on species richness of targeted species per 10 km square can be improved upon. However, different methods had different merits: when assessed using the co-occurrence of areas where species occur with areas targeted through the relevant agri-environment option, one performed well when coverage was assessed as the average coverage of target species in areas eligible for payment, whilst another performed better when allocating resources to areas where rare targeted species are found.
  • Ecosystem Service Maps for decision making: Mapped indicators of ecosystem services are now available to help support decision-making across land use policy priorities (such as a low carbon economy, sustainable food production and water management) by allowing spatially explicit visioning of the Ecosystem Services trade-offs. Some results, based on earlier versions of this work, have been published although most have subsequently been expanded or refined and these new data are available online.
  • Natural Asset Register:  The Natural Asset Register (NAR) has been made publicly available allowing access to datasets describing the distribution of various natural assets including those related to soil, water, and biodiversity. As further datasets become available, the register will provide an inventory of Scotland’s natural assets that will be used in Work Package 1.4 as the basis to explore their sustainable management. Publicising the value of the NAR to all those interested in understanding Scotland’s natural assets has begun, with involvement in several workshops.
  • Cultural Ecosystem Services indicators: Studies exploring new approaches to measuring and mapping cultural ecosystem services (CES) have been completed. One study found the use of touch table technology to be a valuable way of gathering map-based data on CES. A second study, conducted at the Royal Highland Show 2017 involving over 130 participants, used picture-word matching to explore cultural associations with historical landscape elements. These studies have identified approaches that offer promise for rolling out on the larger scale necessary for capturing CES data at the national level.

Progress has been made on all three objectives of this Research Deliverable. A prototype of the Natural Asset Register has been developed and is being adapted to keep pace with fast changing technologies. A review of existing natural capital accounting approaches has identified gaps, and the first set of case studies are being implemented around delivery of services and benefits from forestry and agriculture.  Supporting science to improve the quality of data and the resolution of ecosystem service modelling will enable the Natural asset registers (NAR) and Natural capital accounts (NCA) to be more comprehensive.

Highlights:

  • Review of existing natural asset registers completed, illustrating the need for a trusted knowledge base linking ecosystem function to service to benefit. Confirmed access (as one of only 100 invited users across the world) to GoogleEarth data which will significantly improve our understanding of natural asset trends and condition.
  • Presently developing a preliminary map of different ecosystem services clusters across Scotland, to identify hot-spots and cold-spots of ecosystem service delivery.
  • Organised an Ecosystem Services Community Scotland (ESCom) panel event on “What has the concept of Ecosystem Services done for us? Taking Stock and Looking Forward” involving international academics Robert Costanza and Ida Kubiskewski as well as Scottish Wildlife Trust, SEPA and Scotch Whisky Association (attended by +100 participants).
  • An invited presentation on understanding implementation of the Ecosystem Approach was given at the Science for Biodiversity Forum, which informed the deliberations of the 13th Conference of Parties on the Convention on Biological Diversity (CBD).
  • A review was completed of existing approaches to Natural Capital Accounting, which (along with the review of Natural Asset Registers), was requested by Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) global assessment, Natural England, and the Joint Nature Conservation Committee (JNCC) to inform their work.
  • Our research contributed to further development of SNH’s Natural Capital Asset Index and Framework for Cultural Ecosystem Services.

Future Activities

Development of the Natural Asset Register will continue, focussing on improving its accessibility for different users, including mobile devices, adding new datasets from the SRP and connectivity with other environmental and spatial data.

Modelling work will look at data on soil moisture to explore ecosystem productivity. Nutrient and sediment retention under different climate change and land use scenarios will be modelled to develop an understanding of the impacts on water body ecological status.

Research in support of SNH’s Natural Capital Asset Index will focus on identifying indicators to address gaps in coverage. These will reflect both developments within the SRP and be responsive to needs identified by SNH.

Work on targeting future AECS measures will focus on how biodiversity targeting can also contribute to wider ecosystem services. Output maps will be provided for inclusion in the NAR.

Research will continue to develop and validate indicators for cultural ecosystem services (CES). This will include revision of maps produced in earlier years and community-based exploration of CES in specific regions (e.g. Galloway and South Ayrshire Biosphere). Outputs will be developed for addition to the NAR.

Natural capital accounting work will include case studies on urban greenspace, marine and coastal and peatlands (in conjunction with RD1.1.4). We will also explore the issue of applying accounting approaches in remote areas where small population sizes suggest demand and values for ecosystem services may be low, but their importance may nevertheless be relatively high.
